Fractures in horses refer to the disruption in the continuity of a bone, often resulting from trauma, excessive stress, or pathological conditions. These injuries can vary in severity, from simple, non-displaced fractures to complex, comminuted fractures involving multiple bone fragments. Fractures can affect any bone in a horse's body, but they are most commonly observed in the limbs due to the high mechanical loads these structures endure. Diagnosis typically involves clinical examination and imaging techniques such as radiography or ultrasound to assess the extent and nature of the fracture. Treatment strategies depend on the type and location of the fracture and may include rest, immobilization, surgical intervention, or a combination of these approaches. This page aggregates peer-reviewed research and scholarly articles focusing on the etiology, diagnosis, management, and outcomes of fractures in horses, providing insights into current veterinary practices and advancements in equine orthopedic care.
Martin BB, Reef VB.The successful conservative treatment of an open, displaced fracture of the radius of a horse suggests that conservative treatment should not be ignored when surgery is not an option. The importance of proper soft-tissue management and the use of broad-spectrum antimicrobial treatment in the management of orthopedic injuries is emphasized.
Doran RE, White NA, Allen D.Four adult horses and 3 foals with middle phalangeal fractures were treated by arthrodesis of the proximal interphalangeal joint, using a bone plate. Six of the 7 horses survived greater than 2 years; 2 of the 6 horses had intermittent lameness after hard work, and 4 horses didn't have evidence of lameness. The use of a bone plate for arthrodesis of the proximal interphalangeal joint was a successful treatment alternative for middle phalangeal fractures in horses.
Peterson PR, Pascoe JR, Wheat JD.Fractures of Metacarpal and Metatarsal II and IV (the splint bones) were treated in 283 horses over an 11 year period. In 21 cases the proximal portion of the fractured bone was stabilized with metallic implants. One or more cortical bone screws were used in 11 horses, and bone plates were applied in 11 horses. One horse received both treatments. Complications of screw fixation included bone failure, implant failure, radiographic lucency around the screws, and proliferative new bone at the ostectomy site. Only two of the horses treated with screw fixation returned to their intended use. Compli...
McIlwraith CW, Yovich JV, Martin GS.The technique and results of arthroscopic surgery for the removal of osteochondral fragments from 1,000 carpal joints in 591 horses are reported. Of the 591 horses, 580 were racehorses (including 349 Quarter Horses and 220 Thoroughbreds). The distal aspect of the radial carpal bone was the most commonly affected site, followed by the proximal aspect of the intermediate carpal bone and distolateral aspect of the radius. More than one carpal joint was simultaneously operated on in 58.9% of the Quarter Horses and in 37.4% of the Thoroughbreds. Marked differences in the amount of damage were noted...
Adams SB.A fractured right supraglenoid tubercle in a 15-month-old Thoroughbred gelding was repaired by partial biceps brachii tenotomy, interfragmentary compression, and tension band wiring. The horse is currently being ridden daily and has remained sound for 4 years.
Denny HR, Barr AR, Waterman A.A series of 25 horses with olecranon fractures are reviewed. Twenty-one cases were treated surgically by the application of a tension band plate to the caudal aspect of the ulna. Seventy six per cent of these regained full limb function. The results of treatment are compared with two other series of conservatively and surgically treated cases.
Markel MD, Snyder JR, Hornof WJ, Meagher DM.Nuclear scintigraphy was used to evaluate healing of third metacarpal bone (MC III) fractures in 2 horses (horses 1 and 2) and a third metatarsal bone fracture in 1 horse (horse 3) after stabilization of each fracture with 2 broad dynamic compression plates. In horse 1, the fracture had uniform uptake of 99mTc methylene diphosphonate on days 1, 15, and 30 after surgery. The fracture healed, and the horse was discharged from the clinic on day 52. In horse 2, a 6-cm photopenic region (ie, area of low radioactivity) was seen over the diaphysis of MC III on day 3. The region persisted and became m...
Sullins KE, McIlwraith CW.Transverse or oblique midshaft tibial osteotomies were created in 11 foals. The osteotomies were repaired during the same procedure using external skeletal fixation in either full splint or 3-dimensional (3-D) tent configurations. Four of the six foals receiving the full splint fixator recovered to full soundness; two were euthanized because of complications. The foals receiving the 3-D tent configuration would not bear weight on the limbs and consequently suffered significant secondary fracture disease. These foals were euthanized for humane reasons before the scheduled termination of the pro...
Fischer AT, Stover SM.Third carpal sagittal fractures were found to be related to racing injuries in 10 of 12 horses. These fractures occurred most commonly on the medial aspect of the bone. A dorsoproximal-dorsodistal view of the carpus was required to visualize the fracture in all cases. Healing of the fracture required periods of rest of up to one year. Conservative management of these fractures resulted in return to function in 7 of 12 horses.
Allen D, White NA.Twenty-five cases of fractures of the second and fourth metacarpal and metatarsal (splint) bones were reviewed. Fourteen fractures involved a thoracic limb and 11 involved a pelvic limb. Fractures of the proximal one-third of splint bones are reported in one of two forms: fractures that are closed, or fractures with a permanent or intermittent draining sinus. Thirteen of the fractures presented were closed fractures and the remaining 12 were open. All of the closed fractures were managed by surgical excision of the distal fragment and the exostosis at the fracture site, followed by primary sur...
Snyder JR, Pascoe JR, Hirsh DC.Positive cultures were obtained from 60 equine orthopedic cases during a 12 year period (1974-1985). These cases consisted of 34 long or cuboidal bone fractures, 13 arthrotomy/arthroscopy procedures for removal or internal fixation of a fracture, 7 proximal splint bone fractures, and 6 facial or mandibular fractures. Excluding the 13 arthrotomies, only 10 (21%) of the 47 were open fractures. Multiple organisms were isolated from 36 cases (20 long or cuboidal bone fractures, 7 splint bone fractures, 5 mandibular fractures, and 4 intra-articular fractures). Of the 142 isolates, 35 (24%) were mem...
Little C, Hilbert B.The clinical features of 19 horses with pelvic fractures were reviewed. The most common problem was a grade III or IV unilateral hind limb lameness. The prevalence of fractures was greater in females and horses less than 4 years old. All horses were treated with a combination of analgesic administration and stall rest for 2 to 6 months. Seven of 11 horses (64%) available for long-term follow-up evaluation recovered and 4 of 11 (36%) had no lameness when being ridden. Five of seven (71%) horses with fractures that involved the acetabulum recovered, and 4 (57%) had complete resolution of lamenes...
Greet TR.The case histories of three young thoroughbred racehorses with displaced lateral condylar fractures combined with an axial fracture of the lateral sesamoid bone are described. In two cases the condylar fracture was repaired surgically but both horses developed severe degenerative joint disease and remained lame. The third horse was destroyed humanely. It is important that axial fractures of the sesamoid bone are recognised so that a poorer prognosis can be given for treatment of condylar fractures in racing thoroughbreds.
Bukowiecki CF, Bramlage LR, Gabel AA.Forty-eight limbs of 12 freshly euthanized horses were used to generate data on the strength of the equine suspensory apparatus. The point of failure of the suspensory apparatus of each limb was determined. Immediately before euthanasia, 6 of the 12 horses (thoroughbreds and standardbreds) had been engaged in active training or racing, and six horses in stall and/or pasture activity. In the actively training or racing horses, the point of acute failure of the suspensory apparatus was within the proximal sesamoid bones in 20 (83%) limbs (resulting in 17 apical fractures, 2 basilar fractures, an...
Auer JA, Watkins JP.Fifteen cases of radial fractures in adult horses weighing more than 300 kg are discussed. Four of the horses were destroyed on humane grounds immediately because of a poor prognosis and expense of internal fixation; and two horses at five days and five weeks, respectively after treatment by cast application was initiated. Internal fixation was used in nine horses but of these only two horses recovered completely and resumed their former activities. In eight cases, two plates were applied, one lateral or medial and the other cranial. The internal fixation techniques of all nine horses were scr...
Whitlock MR, Whitlock J, Johnston B.A retrospective study of horse riding injuries in Berkshire was undertaken over a one year period from November 1983. The information was obtained from the Ambulance Service, the Jockey Club and the St. John Ambulance Brigade. There was a total of 103 injured persons with no deaths. Information from the Jockey Club was compared with the other two groups, the former sustaining more limb injuries and the latter more head injuries. A questionnaire was sent to all 42 ambulance patients. Thirty-eight had radiographs taken, 16 of which showed a fracture. Forty-one were wearing some form of hard hat,...
Bowman KF, Sweeney CL, Tate LP.A medial condylar fracture of the third metatarsal bone in a 2-year-old Thoroughbred filly was repaired successfully by use of compression bone plating. At discharge from the hospital, thickening of the metatarsus was evident, and proliferative changes were associated with the site of bone plate application. It was expected that these changes would limit the filly's use as a racehorse, and a return to training was not recommended. Especially in horses that may return to racing, use of compression bone plating initially should not replace stall rest or lag screw fixation treatment of this type ...
Moll HD, Slone DE, Humburg JM, Jagar JE.Three horses and three ponies were treated for traumatic luxation of the proximal intertarsal or tarsometatarsal joint. In each case, there were fractures of one or more tarsal bones. Three of the animals had disruption of one of the collateral ligaments. Five animals were treated by closed reduction and external coaptation. One pony was treated by open curettage, a cancellous bone graft, and cast immobilization. No internal fixation was used in any of these animals. From this series of cases, it would appear that closed reduction and external coaption alone is adequate treatment for most case...
Ellis DR, Simpson DJ, Greenwood RE, Crowhurst JS.A retrospective study of 119 cases of fracture of the proximal phalanx is described. The short incomplete sagittal fracture (split pastern) was most common and carried a good prognosis for a return to racing following conservative treatment. Longer incomplete fractures also had a good prognosis but complete fractures, either through the lateral cortex of the proximal phalanx or through the bone into the proximal interphalangeal joint, required internal fixation. Careful assessment of these and comminuted fractures was essential before surgery was undertaken. Most comminuted fractures were trea...
Voorhout G, Klein WR, Meutstege FJ.An avulsion fracture of the tendon of origin of the extensor digitorum longus muscle is reported in a horse and a cat. This avulsion fracture was due to injury in both animals. There was a striking similarity of radiographic findings in these animals, with involvement of the lateral trochlear ridge and lateral condyle of the femur. The horse was slaughtered because of a poor prognosis as a riding-horse. Fixation of the avulsed fragment with two Kirschner wires resulted in complete recovery in the cat.
Sanders-Shamis M, Bramlage LR, Gable AA.The case records, radiographs and treatment results of 47 consecutive equine radius fractures presented to The Ohio State University Veterinary Hospital from 1975 to 1985 were examined retrospectively. Chip fractures and incomplete fractures were not considered. Both diaphyseal fractures and fractures involving the physes were included. Diaphyseal fractures were placed into three major categories: comminuted, oblique and transverse; and subclassified as proximal, mid-diaphyseal, or distal. Fractures involving a physis were classified using the Salter-Harris classification system. The horses ra...
Hill T, Carmichael D, Maylin G, Krook L.The incidences of fractures and soft tissue injuries during 68397 starts of thoroughbred horses at New York Racing Association tracks were analyzed concerning track condition, dirt and turf tracks, environmental conditions, length of races, location of fractures on the track, and age of horses. It was concluded that the conditions evaluated are of no importance in the occurrence of racing injuries to thoroughbred horses.
Bertram JE, Gosline JM.An engineering fracture mechanics approach was applied to the analysis of the fracture resistance of equine hoof-wall. The relationship between fracture toughness and the morphological organization of the keratin hoof tissue was investigated. Fracture toughness was evaluated using the J-integral analysis method which employs the compact tension test geometry. Tensile tests were also conducted to evaluate the effect of the morphological organization on the stress-strain behaviour. Hoof-wall has greatest fracture resistance for cracks running proximally, parallel to the tubular component of the ...
Yovich JV, Stashak TS, DeBowes RM, Ducharme NG.Fractures of the distal phalanx of the forelimb were diagnosed in 5 colts and 3 fillies ranging in age from 2 weeks to 5 1/2 months at the time of fracture. Three fractures entered the distal interphalangeal joint and 6 fractures (one foal had bilateral fractures) were nonarticular. All foals with articular fractures became sound with conservative treatment. Four of 5 foals with nonarticular fractures became sound with conservative treatment and 1 foal developed separation of the hoof at the coronary band after application of acrylic around the hoof. On the basis of our observations in these f...
Palmer SE.The prevalence of carpal fractures was determined for 211 thoroughbred and 75 standardbred racehorses. Statistically significant differences were found in the location of fractures between the 2 breeds. In the thoroughbred and standardbred groups, total fractures (460) were distributed nearly equally between the left (224) and right (236) carpi. The most common site of fracture in the thoroughbred group was the distal aspect of the radiocarpal bone (112), whereas the most common site of fracture in standardbred horses was the proximal surface of the third carpal bone (61). Slab fractures were ...
Dyson SJ, Greet TR.ALTHOUGH diaphyseal and distal metaphyseal fractures of
the equine humerus have been discussed in the literature
(Johnson, Lowe, Fessler and Amstutz 1974; Vaughan and
Mason 1975; Turner 1984), reports of humeral fractures of
other configurations are rare. Allen and White (1984) described
the successful surgical treatment of a chip fracture of the greater
tubercle of the humerus. This report describes the clinical
features and treatment of a fracture of the deltoid tuberosity.
Speirs VC, Anderson GA, Bourke JM.The efficacy of treating carpal lesions by arthrotomy was evaluated in 210 Thoroughbred racehorses, using survival analysis to compare their racing performances and earnings with those of 840 control horses. The treated horses were significantly inferior with respect to races contested, and wins plus places (P less than 0.001) and races won (P less than 0.01). There was no difference with respect to earnings (P less than 0.1); after adjusting for other factors, arthritis, site of fracture and presence of a displaced chip had no effect on racing performance in horses with a single-site lesion i...
Auer JA, Watkins JP, White NA, Taylor TS, Rooney JR.Fractures of the fourth carpal bone were diagnosed in 5 horses; 3 fractures were associated with fracture of the intermediate carpal bone. The diagnosis was delayed in all 5 horses, apparently because of the moderate nature of the clinical signs. Open surgical reduction with lag screw type fixation was used in all horses. Because of delayed treatment, transfixation of carpal bones (necessary for stability), and surgical trauma, degenerative joint disease with osteophyte formation occurred in all 5 horses. None of the 5 horses was able to begin or return successfully to work, although 4 of the ...
Caron JP, Barber SM, Bailey JV, Fretz PB, Pharr JW.Periorbital skull fractures were diagnosed in 5 horses, and were associated with ophthalmic complications including corneal ulceration, uveitis, and entrapment of the eye by retrobulbar bone fragments. Physical examination was of greater diagnostic use than radiography. Surgical repair was performed on all horses and was associated with a more favorable postoperative appearance in horses treated acutely; however, the cosmetic results were considered acceptable in all horses. Major postoperative complications were not observed.
Auer JA, Watkins JP.In recent years fracture fixation in the horse has changed significantly. New devices, mainly adapted from the human field, have been successfully introduced into large animal surgery. Examples of such implants include the DCS/DHS implant system, the self-tapping screw, the cannulated screw, and the pinless external fixator. However, new devices have also been developed exclusively for equine fracture management, including the interlocking intramedullary nail and the external skeletal fixation device. With these devices the surgeon has more options for repairing fractures in horses. Neverthele...
Greet TR.The case histories of three young thoroughbred racehorses with displaced lateral condylar fractures combined with an axial fracture of the lateral sesamoid bone are described. In two cases the condylar fracture was repaired surgically but both horses developed severe degenerative joint disease and remained lame. The third horse was destroyed humanely. It is important that axial fractures of the sesamoid bone are recognised so that a poorer prognosis can be given for treatment of condylar fractures in racing thoroughbreds.
Pilsworth RC, Shepherd MC, Herinckx BM, Holmes MA.During a two year period, sagittal fractures of the wing of the ilium were diagnosed in 10 Thoroughbred horses. All were spontaneous fractures sustained during normal exercise in training and racing, with no history of inciting trauma. When ultrasound scans of the surface of the pelvis were performed, the fracture was clearly visible as a discontinuity of the sacral wing of the ilium. In 3 horses, an irregular contour suggestive of periosteal callus was seen in the vicinity of the acute fracture. All horses examined by gamma scintigraphy had a focal increase in uptake of isotope just lateral t...
Miyakoshi D, Higuchi T, Ikeda H, Sato M, Yoshimura S.To report a surgical technique and an outcome for the repair of a displaced, transverse scapular body fracture with locking compression plates (LCPs) in a colt. Methods: One 5 month old Thoroughbred colt. Methods: Case report. Methods: A colt sustained an unstable, comminuted, transverse fracture of the scapular body. Three 4.5/5.0 mm LCPs were used with 6.5 mm cancellous screws, 4.5 mm cortex screws, and 5.0 mm locking head screws. Implants were removed 2 months after surgery. Results: Surgical site infection was identified by purulent discharge at the distal aspect of the suture li...
Martin BB, Nunamaker DM, Evans LH, Orsini JA, Palmer SE.Circumferential wiring was used to repair 12 mid-body fractures and four large basilar fractures of proximal sesamoid bones in 15 horses. Eighteen-gauge stainless steel wire was placed around both fragments in five horses, and through the proximal fragment and around the distal fragment in 10 horses. The horses were returned to work when they were clinically sound and fracture healing was evident radiographically. Eleven horses resumed athletic performance, three horses were used as breeding animals, and one horse was retired. Five horses performed at an athletic level equal to or better than ...
Janicek JC, Rodgerson DH, Hunt RJ, Spirito MA, Thorpe PE, Tessman RK.Olecranon fracture is a common orthopedic problem in juvenile horses. Prognosis for complete fracture healing when various methods of internal fixation are used is good; however, the impact of olecranon fracture stabilization on the likelihood that foals will start on a racecourse is unknown. Medical records of foals undergoing internal fixation for an olecranon fracture were reviewed. The dam's foaling records were obtained and lifetime racing records were then retrieved for both the affected foals and 1 of their siblings. Twenty-two of 24 repaired fractures healed completely, subsequently, 1...
Nelson BB, Lawless SP, McIlwraith CW.Characteristics and outcomes after surgical repair of third carpal bone (C3) slab fractures involving both radial and intermediate facets in racing Quarter Horses are unknown. Objective: To describe the pre- and intraoperative characteristics of C3 slab fractures of both radial and intermediate facets in Quarter Horses and to report on the long-term outcomes after internal fixation. Methods: Retrospective case series. Methods: Case records were collected from racehorses with C3 slab fractures between 2008 and 2020. Inclusion criteria required arthroscopic-guided repair of C3 slab fractures inv...
Yovich JV, Aanes WA.A fracture of the caudal portion of the greater tubercle of the humerus was diagnosed in a 16-month-old Thoroughbred filly. Initially the fracture caused severe lameness. Radiography of the affected shoulder revealed the fracture fragment to be extra-articular, with a surrounding bony callus and no evidence of joint disease. After 5 weeks rest in a stall and 11 months at pasture, the filly was trained and raced without lameness.
Spurlock GH.Seemingly, propagation of a dorsal cortical fracture in the third metacarpal bone developed after continued race performance in 2 horses. Historically, both horses had intermittent lameness that had responded to nonsteroidal anti-inflammatory drugs and brief rest periods. However, lameness in both horses had increased in severity. Radiography revealed a dorsal cortical fracture of the third metacarpal bone, with propagation of the fracture plane proximally. Fractures were incomplete and healed with stall rest in both horses.
Bukowiecki CF, van Ee RT, Schneiter HL.A comminuted scapular fracture in a foal was treated surgically by use of 2 dynamic compression plates. The plates were applied upside down, so that the convex surface of the plate faced the bone. At 5 months after surgery, the plates were removed, and the foal recovered without complications.
Cervantes C, Madison JB, Ackerman N, Reed WO.Between January 1985 and May 1989, 53 Thoroughbred horses (mean age 3.2 years) were surgically treated for dorsal cortical fractures of the third metacarpal bone (MC III). All horses were treated with cortical drilling through the fracture line (osteostixis). Diagnosis of the fractures was confirmed by xeroradiography. Lifetime racing records were obtained for all horses. Forty-seven horses returned to racing after surgery (89%). The mean time between surgery and the first race was 6.8 months. Horses had a mean of 10.9 starts before surgery and 16.1 starts after surgery. The mean earnings per ...
Kirker-Head CA, Fackelman GE.Four long bone fractures with a short distal fragment were repaired with a cobra head bone plate alone (2 cattle) or in combination with a straight, broad dynamic compression plate (2 horses). Three fractures were of the distal femur (1 horse, 2 cattle) and one was of the distal radius (1 horse). The long-term outcome of the three femoral fractures was soundness in one case and mild lameness in two. Although satisfactory bone healing progressed in the horse with the radial fracture, laminitis in the contralateral forelimb necessitated euthanasia at week 6.
Malek G, Richard H, Beauchamp G, Laverty S.Focal bone microcracks with osteoclast recruitment and bone lysis, may reduce fracture resistance in racehorses. As current imaging does not detect all horses at risk for fracture, the discovery of novel serum biomarkers of bone resorption or osteoclast activity could potentially address this unmet clinical need. The biology of equine osteoclasts on their natural substrate, equine bone, has never been studied in vitro and may permit identification of specific biomarkers of their activity. Objective: (1) Establish osteoclast cultures on equine bone, (2) Measure biomarkers (tartrate resistant ac...
Little CB, Hilbert BJ, McGill CA.The clinical features of 21 horses which sustained head fractures are reviewed. There was a higher incidence of fractures in males and Standardbred horses. Surgical treatment was practical and successful in most cases when the fractures involved the bones of the jaws and the face. Fractures which involved the cranial cavity or the cranial nerves were difficult to treat and usually held a poor prognosis.
Turner AS, Milne DW, Hohn RB, Rouse GP.Fracture of the capital femoral epiphysis occurred in three foals. One fracture was repaired by means of pinning under radiographic control and the two other fractures were repaired by means of trochanteric osteotomy.
Honnas CM, Snyder JR, Meagher DM, Ragle CA.Traumatic disruption of the suspensory apparatus is a catastrophic injury in the horse. Although this injury has been described in the adult, little information is available in the foal. This paper describes 3 foals with metacarpophalangeal joint instability caused by traumatic disruption of the suspensory apparatus. Two foals had biaxial proximal sesamoid fractures in a single forelimb, and 1 foal had avulsion of the distal sesamoidean ligaments in 1 forelimb plus biaxial proximal sesamoid fractures in the other forelimb. The foals with single forelimb involvement were managed with splints, a...
Molnar R, Barber SM, Pharr JW, Panizzi L, Plaxton A.A Quarter horse gelding sustained fracture and displacement of spinous processes T2-T10. Radiographic evidence of healing was seen 3 mo following injury, and at 2 years post-injury all spinous processes had healed and undergone partial re-alignment. This re-alignment has not been reported before. Un hongre Quarter horse a subi une fracture et un déplacement des apophyses épineuses T2–T10. Les preuves radiographiques de la guérison ont été observées 3 mois après la blessure et 2 ans après la blessure toutes les apophyses épineuses avaient guéri et subi un réalignement partiel. Ce ...
Lindsay WA, Horney FD.During a 6-year period, carpal arthrotomies were performed on 89 horses with carpal fractures. Fifty-two percent of the fractures involved the left forelimb; the 3rd carpal bone was most often involved (42%), followed by the radial carpal bone (30%). The effect of surgery on the performance of a subgroup of 48 thoroughbreds was evaluated by comparing the number of starts, level of racing (claiming value), and earnings for the 12 months of racing preceding and following arthrotomy. The data indicated that carpal arthrotomy in the Thoroughbred carries with it a favorable prognosis inasmuch as 80...
MacKay AV, Panizzi L, Sparks HD, Barber SM.To report complications of arthrodesis of the carpometacarpal (CMC) joint using a drilling technique in an adult horse. Methods: Case report. Methods: Horse (n = 1). Methods: A 12-year-old Quarter Horse mare with CMC osteoarthritis (CMC-OA) had arthrodesis under general anesthesia in right lateral recumbency. Under fluoroscopic guidance, a 4.5 mm drill bit was inserted at 3 drilling sites 5-6 cm into the CMC joint and was fanned 30-45° in the plane of the joint and 5-10° in the long axis of the limb to destroy articular cartilage and expose the subchondral bone. Results: The horse pr...
Orsini JA, Buonanno AM, Richardson DW, Nunamaker DN.A Salter-Harris type-II fracture of the distal portion of the femur in a 1-year-old Pony of America was repaired by use of lateral plating combined with interfragmentary compression. The configuration of the fracture and the method of internal fixation with a condylar buttress plate were unique and resulted in primary bone healing, seen at the 5-month follow-up examination.
Johnson PJ, Allhands RV, Baker GJ, Boero MJ, Foreman JH, Hyyppa T, Huhn JC.Incomplete linear tibial fractures were identified in two horses with the aid of scintigraphy. Both horses were treated successfully by strict stall confinement, and both returned to normal athletic activity. Scintigraphy can be used to facilitate the generally difficult diagnosis of incomplete tibial fractures.
van Veen L, de Greef RJ.A non-displaced radialfracture of a horse was,diagnosed. The horse had an open fracture resulting from external trauma. A diagnosis was made on radiographs taken 48h after trauma. The horse was treated conservatively by box rest and Robert-Jones bandages. After 7 days the wound was opened to let the wound drainage necrotic material and small sequesters and was washed every other day. After 7 weeks, radiographs showed complete consolidation. Four months after the injury the horse was back to work at his former level and is still working two years after the incident.
Mageed M, Steinberg T, Drumm N, Stubbs N, Wegert J, Koene M.Fractures involving the proximal one-third of the splint bone are relatively rare and are challenging to treat. A variety of management techniques have been reported in the literature. The aim of this retrospective case series was to describe the clinical presentation and evaluate the efficacy of bioabsorbable polylactic acid screws in internal fixation of proximal fractures of the 2nd and 4th metacarpal and metatarsal bones in horses. Methods: The medical records, diagnostic images and outcome of all horses diagnosed with a proximal fracture of the splint bones and treated with partial resect...
Lection J, Delvescovo B, Percival A, Wu T, Southard T, Diel de Amorim M, Cheong SH.In utero fracture and malunion of long bones is a rare condition in horses. Most foals with in utero fractures are aborted, and the identification of a fetal in utero fracture in a mare with dystocia has not been reported. A 7-year-old multiparous Standardbred mare presented to a referral center for correction of dystocia. Assisted vaginal delivery and controlled vaginal delivery attempts were unsuccessful mainly because of contracted tendons impeding mutation. As the foal was alive, a cesarean section was elected. The foal was delivered but ultimately euthanized because of the congenital abno...
Lucas JM, Ross MW, Richardson DW.A retrospective study of 176 Standardbred horses that had arthroscopic surgery for carpal chip fractures over a 7 year period was done in order to determine fracture location and post operative performance. Chip fractures of the proximal third carpal bone and the distal radiocarpal bone occurred with equal frequency (49.2 and 49.6% respectively), and chip fractures involving the antebrachiocarpal joint were rare. Trotters had significantly more third carpal bone lesions than radiocarpal bone lesions when compared to pacers (P = 0.0304). Seventy-four per cent of horses made at least one start f...
Shamis LD, Sanders-Shamis M, Bramlage LR.A 3-week-old Standardbred filly had a non-weightbearing forelimb lameness caused by scapular neck fracture. The fracture was repaired with 2 dynamic compression plates placed 90 degrees to each other. A 10-hole 4.5-mm narrow dynamic compression plate was placed on the cranial aspect of the scapular spine, and a 10-hole 3.5-mm dynamic compression plate was placed caudal to the scapular spine. One year after surgery, the filly was not lame when exercising in the pasture, and muscle atrophy was not evident on the affected limb. Eighteen months after surgery, the filly was in race training with no...
Jones SA, Whitcomb MB, Vaughan B, Goorchenko G, Busch R, Kilcoyne I, Spriet M.Femoral fractures are often catastrophic in large animals. Radiographic diagnosis is limited by patient size and feasibility, especially in ambulatory settings. Ultrasonography is widely available and may provide an alternative to radiography for definitive diagnosis. 12 large animals (6 horses, 5 cattle, and 1 elephant). Retrospective analysis of large animal patients diagnosed with femoral fracture by use of femoropelvic ultrasonography (2000 to 2019). 5 of 12 cases were ≤ 1 year of age. The remaining 7 cases were 2 to 33 years of age (median, 13 years). All patients developed severe acute...
Beroza GA, Gentile DG, Goodness P, Charles R.A Robert Jones bandage modified to include a steel walking bar frame and, in one case, side-supporting bars, was applied as a splinting device in 4 horses with hindlimb fractures (3 tarsal and 1 middle phalangeal). The modification was used as an adjunct to previous casting therapies or as a means for handling casting failures or soft tissue problems encountered during the casting period. This means of stabilization is easily adapted to replace a problematic cast in various clinical settings, is easily applied in the standing patient, is easily changed and adjusted on a regular basis, has mini...
Morgan JM, Galuppo LD.Management of fractures in the field starts with successful assessment and stabilization of the patient by the practitioner on the front lines. A careful examination is vital to succesful patient management. This includes identifying the fracture location and severity, evaluating skin integrity and potential contamination of the fracture, and treating any ongoing hemorrhage, hypovolemia or stress. Appropriate application of splints in the field will minimize ongoing tissue damage and improve patient comfort. This ultimately aids further assessment, facilitates referral, and improves opportunit...
Vail TB, McIlwraith CW.An intraarticular osteochondral chip fracture of the distal dorsolateral aspect of the right hind middle phalanx in a 4-year-old Dutch Warmblood gelding was removed arthroscopically. Accessibility and visibility of the fragment were excellent, and there was minimal soft tissue trauma.
