Injury in horses encompasses a range of physical traumas that can affect various tissues and structures, including bones, muscles, tendons, and ligaments. These injuries can arise from numerous causes, such as accidents, overexertion, or improper handling. Common types of equine injuries include fractures, sprains, strains, and lacerations. The management and treatment of these injuries require an understanding of equine anatomy and biomechanics, as well as appropriate veterinary care. This page collects peer-reviewed research studies and scholarly articles that explore the causes, diagnosis, treatment, and prevention of injuries in horses, providing insights into their impact on equine health and performance.
Köhler H, Oberlojer HG.In the ampulla roof of the wave-like extending horse rectum the muscular coat is only weakly developed as a deltoid-shaped tunica muscularis area, thus forming a place of minor resistance. With regard to the degree of development of the muscular coat a rectal ampulla with a stable form and strong muscles can be distinguished from an ampulla with a labile form and weak muscles. The rupture of the intestinal wall in this region in the case of rupture-experiments as well as the frequent occurrence of diverticula reveals this area as being a place of minor resistance which requires extreme caution...
Adams OR, Schneider RK, Bramlage LR, Easley KJ, Schneider JE.Suprascapular nerve decompression has proven to be a useful treatment for refractory neuropraxia in horses. The surgical procedure used to effect that decompression is described. The surgery can be undertaken when conservative treatment has failed, but the sooner the surgery is done, the more likely the muscle mass is to be cosmetically satisfactory.
McKibbin LS, Paraschak DM.Bone spavin, splint, and fractured splint bone injuries have been treated with varying methodologies at Wheatley Hall Farm Equine Clinic. Cryosurgery is the most successful. With cryosurgery the small, pain-producing afferent C fibers are destroyed, and painful neuromas do not return. Injured sites were cryosurgically treated with liquid nitrogen for a double freeze-thaw period of 45 sec. 5 sec, 45 sec. Before and after treatment comparisons were conducted on study standardbreds. In all three injury groups, results showed that the standardbreds tended to race as well or with improved times and...
Bixby-Hammett DM.In brief: In a two-year study of the estimated 13,428,000 hours of horse activities by 18,408 US Pony Clubs (USPC) members aged 6 to 21 in scheduled supervised programs, there were 64 accidents resulting in 88 injuries in 16 areas of the body. The head/face was the area most often injured (27.27%), and bruise/abrasion was the most common type of injury (28.26%). Cross-country riding was the most dangerous event (42.31%). Unexpected actions of the horse caused many accidents-25% occurred when the horse bucked and threw the rider, 23.08% when the horse refused a jump, and 17.31% when the horse f...
Blue MG.Minor accidents during natural mating are common occurrences during the breeding of horses. Mares may suffer from a variety of genital injuries including vulval separations, vaginal lacerations and, less commonly, vaginal rupture. Possible sequelae to, and management of, these injuries are described, with additional mention of false entry by the stallion and persistent hymen in maiden mares. Vaginal rupture during natural mating can lead to death of the mare. The implications for litigation involving veterinary surgeons and horse breeders are discussed.
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.
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...
Muwanga LC, Dove AF.We report the frequency with which horse riders with a significant head injury present to a large accident and emergency department. We have also recorded details about the use of headwear and conclude that horse-riding is associated with a serious risk of head injury and 'protective' headwear may not always protect.
Lunn DP, Peel JE.A five-year-old standardbred mare suffered a cervical oesophageal rupture subsequent to a kick. Marked cellulitis and extensive soft tissue damage resulted. Treatment consisted of creating an oesophageal fistula, local debridement and systemic antibiotics. The mare made a long but successful recovery. Treatment of oesophageal rupture in the horse is discussed.
Markel MD, Richardson DW.In a retrospective study, we examined the case records for 69 horses with noncomminuted fractures of the proximal phalanx, excluding proximal chip fractures. Forty-nine of the horses sustained the fracture while racing or training for racing. Radiographic examination of all affected limbs was performed, and fractures were classified into 6 noncomminuted types: midsagittal fractures, including short incomplete midsagittal fractures, long incomplete midsagittal (LIMS) fractures, and complete midsagittal (CMS) fractures; dorsal frontal fractures; distal joint fractures; plantar process fractures;...
Collier MA, Kallfelz FA, Rendano VT, Krook LP, Schryver HF.The use of capacitively coupled low-voltage signals for stimulation of osteogenesis has been reported in a variety of animal models. Electrically induced osteogenesis was investigated with a capacitively coupled electric field on a radius (distal-lateral orientation) osteotomy model, in conjunction with internal fixation and postoperative loading. Twelve adult horses of either sex were allotted to 2 groups of 6; 1 group was given electrical stimulation and the other served as controls. A low-voltage high-frequency capacitively coupled electrical signal was locally and continuously applied to t...
Tulleners EP, Richardson DW, Reid BV.Three mares were treated for vaginal evisceration of a portion of the small intestine. Evisceration occurred in 2 mares shortly after breeding accidents in which the stallion's penis penetrated the vaginal fornix dorsal to the cervix. The affected bowel was replaced through the laceration, and the vaginal defects were sutured with the mares standing, utilizing epidural anesthesia. One mare recovered without complications, was subsequently bred, and delivered a foal with no difficulty. The other mare developed signs of a strangulating small intestinal obstruction 24 hours after the injury, nece...
Barclay WP, Foerner JJ, Phillips TN.Axial sesamoid injuries were found in 4 of 18 horses with lateral condylar fractures of the metacarpus or metatarsus. The injuries appeared as axial sesamoid fractures or progressive demineralization of the axial border of one of the sesamoids. None of the horses with axial sesamoid injuries returned to performance soundness. Axial sesamoid injury appeared to be an indication of severe fetlock trauma due to condylar fracture. Such injuries appeared to indicate a poor prognosis for return to performance soundness.
Rossdale PD, Hopes R, Digby NJ, offord K.An epidemiological study of wastage among racehorses was conducted in 1982 and 1983 among six stables, five of which were in Newmarket. The basis of the survey was the inability of horses to take part in cantering exercise as a result of injury or disease. The greatest number of days lost to training was caused by lameness (67.6 per cent) and respiratory problems (20.5 per cent). Conditions of the foot (19 pe cent), muscle (18 per cent), carpus (14 per cent), fetlock joints (14 per cent), tendons (10 per cent) and sore shins (9 per cent) were the major reasons for training days being lost in 1...
Pounder DJ.The fatalities associated with the riding and handling of horses in South Australia over the 11-year period 1973-1983 are reviewed. There were 18 deaths, including two sudden natural deaths in the saddle and one drowning. The 15 cases of horse-related trauma represent a death rate of approximately one per million population per annum. Thirteen of the deaths were the result of a head injury after a fall. Nine persons were not wearing protective headgear. The two principal groups at risk were male professional riders with a mean age of 32 years and female amateurs with a mean age of 19 years.
Verschooten F, Gasthuys F, De Moor A.An experimental and clinical study to investigate the aetiology of distal splint bone fractures is described. In vitro, extension of the fetlock did not appear to alter the position of the distal ends of the splint bones, although tension in the interosseous tendons increased. Flexion of the fetlock resulted in slight outward displacement of the distal ends of the splint bones. It is suggested that concurrent desmitis of the suspensory ligament can cause movement of the ends of the splint bones thus predisposing to a fatigue fracture. In a clinical study of 87 horses, 114 splint bone fractures...
Bailey JV, Barber SM, Fretz PB, Jacobs KA.The records of 13 horses of various breeds with subluxation of the radiocarpal, intercarpal or carpometacarpal joint, or combinations of these were reviewed. Subluxation was most common at the carpometacarpal joint (n = 10) and concomitant fractures of individual carpal bones or metacarpus II and IV were seen (n = 12).Treatment comprised of immobilization in a full leg plaster cast for from four to 18 weeks. Three animals were euthanized, two because of cast complications and one because of a request by the owner. The remaining ten were saved to function as breeding animals.
Donecker JM, Bramlage LR, Gabel AA.Twenty-nine fractures of the olecranon process of the ulna in horses treated at The Ohio State University College of Veterinary Medicine from 1973 through 1983 were evaluated. The objectives of the study were to determine the prognosis for various configurations of fractures of the olecranon process of the ulna, to determine what preoperative factors influenced the prognosis, and to evaluate the efficacy of the treatment methods used. The fractures were placed in one of 4 categories on the basis of severity of the injury: type-1 fractures involved the physeal plate; type-2 fractures involved t...
Lavach JD, Severin GA, Roberts SM.Perforating corneal wounds in horses have a better prognosis than wounds that involve both cornea and sclera. Sharp objects tend to produce more isolated corneal wounds and have a better prognosis than do wounds produced by blunt objects. The records of 43 horses that sustained penetrating wounds of the cornea were reviewed. In addition, the surgical approach and postoperative wound management is described. The report attempts to provide more information regarding the management of ocular trauma in horses.
Williams IF, McCullagh KG, Goodship AE, Silver IA.The histological and morphological characteristics of the scar tissue formed during healing after traumatic equine tendon injury have been compared with those of scar tissue produced in response to an enzyme-induced pony tendon injury. Several techniques are currently in use in the treatment of equine tendon sprain and this work formed part of a study of their respective efficacy. It was concluded that the enzyme-induced lesion is resolved by a reparative process very similar in its prognosis and extent to that following a naturally occurring tendon sprain. It may therefore justifiably be used...
Morgan RF, Nichter LS, Friedman HI, McCue FC.Three men with thumb injuries sustained during rodeo roping competition have been treated recently. Two of the thumbs were amputated, and the third was partially avulsed. The mechanism of injury was identical in all three cases. The thumbs were entwined between the rope and saddle horn while reducing the slack in the rope and then subjected to shearing and crushing forces as tension was placed on the rope. These injuries emphasize the importance of keeping the thumb upward and clear of the rope to avoid entrapment between the rope and saddle horn.
McKibbin LS, Paraschak D.The final and last-quarter race times and racing classes for a group of Standardbreds were analyzed before and after infrared laser light treatment. These horses had either check ligament injuries, plantar desmitis or pharyngeal lymphoid hyperplasia. A 904-nm infrared laser was used to treat check ligaments at 146 Hz for 26 sec/cm2 of affected area, acute plantar desmitis at 73 Hz and chronic plantar desmitis at 292 Hz for 26 sec/cm2 of affected area, and pharyngeal lymphoid hyperplasia at 146 Hz for 5 minutes. Of 35 horses treated for check ligament injuries, 80% had similar or faster final r...
Geiser DR, Walker RD.The pathophysiology and histopathology of thermal burns in large animals is very similar to that in humans. Burns are classified as first degree, superficial and deep second degree, third degree, and fourth degree, depending upon the depth of thermal injury. Most severe burns will produce a local and a systemic response--both of which must be properly treated to increase the patient's chances for survival. The systemic response is mainly characterized by hypovolemia, fluid and electrolyte loss, protein loss, pulmonary edema, increased caloric requirements, and depressed immune responses. The l...
Dik KJ.Common soft tissue disorders of the equine carpus are fluctuating or firm soft tissue swellings, wounds and draining tracts. Survey radiography may show the size, position and origin of the swellings and reveals soft tissue calcification, accumulation of air and radiopaque foreign material. Contrast radiography enables accurate visualization of the size, shape, position and origin of fluctuating soft tissue swellings, demonstrates abnormal intersynovial communication and allows precise demonstration of the extent of puncture wounds and draining tracts. Ultrasonography allows differentiation be...
Melly V, Ortved KF, Manzi TJ, Richardson DW, Stefanovski D, Wulster KB.Increasing accessibility and advancements in computed tomographic (CT) imaging improve understanding of the contributors to poor performance in the Thoroughbred racehorse. Objective: To characterise an unreported site of tarsal subchondral bone injury (SBI) in Thoroughbred racehorses. Methods: Retrospective, cross-sectional analytical study. Methods: Tarsal CT scans of 108 horses were reviewed for evidence of SBI in the dorsodistolateral calcaneus (DDLC). Signalment, including age, breed, sex, and discipline of horses, was recorded. The association of DDLC SBI with Thoroughbred racehorse compa...
Costa F, Brunsting J, Corrêa F.This case report describes a 16-year-old jumping stallion that had a marked swelling over the left antebrachial area along with substantial lameness after a fall. The horse was weight bearing but lame (4/5; AAEP scale) at the walk with marked enlargement in the caudal aspect of the antebrachial region. After a static musculoskeletal examination, radiography and ultrasonography the horse was diagnosed with flexor muscle myopathy and presumptive extremity compartment syndrome. Following medical treatment, the horse improved clinically over several days. Six-months post injury the horse showed fl...
Warnock WR, Marsh CA, Hand DR.The purpose of this study was to report long-term outcome following arthroscopic debridement of articular cartilage lesions of the distal interphalangeal joint, diagnosed with high-field magnetic resonance imaging. Diagnosis was based on the results of diagnostic anesthesia, magnetic resonance imaging (MRI), and arthroscopy. Ten horses underwent arthroscopic evaluation for cartilage injury and received various intra-articular therapies after surgery. Three of ten horses had lesions that were surgically inaccessible. Four horses became sound and returned to their preoperative level of athletici...
Reeves MJ, Trotter GW.A 14-year-old Quarter Horse x Thoroughbred gelding was admitted to the teaching hospital because of inability to bear weight on its right hind limb, associated with a severe deviation of the tarsus. The provisional diagnosis was tarsal joint luxation or fracture. Radiography revealed complete luxation of the tarsocrural joint. The luxation was reduced, using minimal force. The horse was confined to a box stall and was maintained in a full-length hind-limb cast for 33 days. Box stall confinement was continued for 3 months after removal of the cast. On reexamination 18 months after the injury, t...
Clark JM, Connor TA, Post A, Hoshizaki TB, Gilchrist MD.Current equestrian standards employ a drop test to a rigid steel anvil. However, falls in equestrian sports often result in impacts with soft ground. The purpose of this study was to compare head kinematics and brain tissue response associated with surfaces impacted during equestrian accidents and corresponding helmet certification tests. A helmeted Hybrid III headform was dropped freely onto three different anvils (steel, turf and sand) at three impact locations. Peak linear acceleration, rotational acceleration and impact duration of the headform were measured. Resulting accelerations served...
Phillips TJ, Wright IM.Ten carpi from juvenile Thoroughbred horses were dissected in detail to record the anatomy of the palmar intercarpal ligaments (PICLs). These were found not to be substantially attached to the palmar carpal ligament. The lateral PICL was sited at the convergence of the palmar aspects of the third, fourth, intermediate and ulnar carpal bones and aligned predominantly in a proximodistal direction. The medial PICL had a large origin distally on the lateral aspect of the radial carpal bone (Cr) and attached to third (C3) and second (C2) carpal bones with apparently separate fibre orientations. Fib...
Becker CK, Savelberg HH, Buchner HH, Barneveld A.To evaluate clinical and biomechanical consequences of desmotomy of the accessory ligament (AL) of the deep digital flexor tendon (DDFT) of equine forelimbs and determine whether this procedure is a viable treatment for chronic desmitis of the AL-DDFT. Methods: 6 adult Standardbred trotters. Methods: Biomechanical recordings obtained before and 6 months after desmotomy were compared. Walk and trot joint angles, ground reaction forces, peak joint moments, and tendon forces were assessed. Results: Within 10 days after surgery, all horses were sound at a trot. Swelling, increased carpal flexion i...
Young N, Corletto F, Wright I.To identify prognostic factors for return to racing after lag screw repair of condylar fractures and develop a predictive model for return to racing. Methods: Retrospective cohort study. Methods: A total of 356 horses referred to a single referral hospital in the UK with a third metacarpal/metatarsal condylar fracture between January 1999 and December 2018. Methods: Age, sex, fracture site, fracture characteristics, surgery related variables and complications were retrieved from case records. Data were divided into two sets for model training and model validation. Univariable analyses were per...
Muñiz Fontán M, Moure González JD, Mirás Veiga A, Rodríguez Núñez A.Children's equestrian activities in the domestic, play activities, sports and educational areas are relatively frequent, and are not exempt from risks. Nevertheless, there is a lack of data on horse-related injuries, their circumstances and the key points for their prevention. Methods: Retrospective and descriptive study of pediatric equestrian injuries admitted to Hospital between July 1997 and September 2008. Results: A total of 17 patients with ages between 4 and 17 years were analyzed. There were 14 accidental falls, 2 kicks and 1 bite, and 8 patients had lost consciousness after the accid...
Buzzetti AP, Nothaft IT, Paganela JC, Franzan BC, Braga GI, Barreira APB, de Lima LR, de Almeida FQ.This study aimed to perform ultrasonographic evaluation of the digital flexor tendons of jumping horses undergoing complementary training on a treadmill. Fifteen Brazilian Sport horses were divided into two groups: Group I with 7 animals in physical training complementary to the standard training at the Brazilian Army's Riding School; and Group II with 8 animals in standard training used in the Brazilian Army's Riding School. Complementary training was performed on a treadmill on an inclined plane. Ultrasonographic images were taken at the beginning and at the end of training. The left thoraci...
Zetterström SM, Boone LH, Weatherall KM, Caldwell FJ.To describe a minimally invasive technique for semitendinosus tenotomy with ultrasonographic guidance and to evaluate procedural complications. Methods: Experimental study. Methods: Cadaveric equine hind limbs (n = 16). Methods: A stab incision was performed distocaudal to the tibial insertion of the semitendinosus muscle with ultrasonographic assistance. After transection of the tendon with an arthroscopic retrograde knife, the tendon edges palpably retracted, and complete transection was confirmed by ultrasound. Limbs were dissected to confirm the degree of tendon transection and to identify...
McCarthy PH.A description is given of 75 features present in the normal tarsus of the standing horse which are apparent due to visible skin contours overlying them. Depending on whether or not the pelvic limb is supporting full weight or resting, some contours alter their configuration. Therefore the contour of each underlying feature is described separately for each stance of the limb. It is considered that visual inspection and identification of the apparent superficial features of the normal equine tarsus form the basis of orientation and clinical inspection. Furthermore, these features provide referen...
Hall S, McElligott S, Sadek AR, Griffith C, Waters R, Nader-Sepahi A. Accidents during sporting activities are a common cause of head injury, particularly in children and young adults. Whilst most sporting head injuries are minor, there remains a proportion which is associated with high morbidity and mortality. The epidemiology of sports associated head injuries is variable based on geographical region so the aim of this study was to review the management and outcomes of sporting head injuries managed by a single neurosurgical unit in the South of England. A retrospective review of the Trauma Audit and Research Network database was conducted for all patients ad...
van den Belt AJ, Becker CK, Dik KJ.The clinical and ultrasonographic features of desmitis of the accessory ligament of the deep digital flexor tendon (carpal check ligament) are reported in a series of 24 horses. Lameness associated with the carpal check ligament especially was found in Warmblood riding horses ranging in age from 6 to 18 years with a mean age of 11.3 years. The most striking clinical feature was a firm, painful swelling medially and laterally in the proximal and/or mid metacarpal region, corresponding with the dorsoproximal-palmarodistal oblique direction of the carpal check ligament. Sonographically swelling o...
Gaughan EM.Skeletal origins of exercise intolerance and performance failure can reside in multiple tissues. Diagnosis of injury that results in an ability to continue to exercise, yet inefficiently do so, requires familiarity with evaluation of subtle lameness and often with the specific demands of the different equine sports. Imaging is usually vital to diagnosis development and understanding of lesion influences on locomotion. Therapy is lesion dependent. Return to competitive exercise and performance is dictated by an understanding of skeletal tissue response to injury, rational progressive treatment,...
Dabareiner RM, White NA, Sullins KE.Medical records, radiographs, and sonograms of 63 horses with metacarpophalangeal joint synovial pad proliferation were examined retrospectively. All horses had lameness, joint effusion, or both signs associated with one or both metacarpophalangeal joints. Bony remodeling and concavity of the distodorsal aspect of the third metacarpal bone (Mc3) just proximal to the metacarpal condyles was identified by radiography in 71 joints (93%); 24 joints (32%) had radiographic evidence of a chip fracture located at the proximal dorsal aspect of the proximal phalanx. Fifty-four joints (71%) were examined...
Lutter JD, Cary JA, Stephens RR, Potts LB.Determine the relative stiffness of 3 bandage/splint constructs intended for emergency fracture stabilization. Methods: Experimental model. A single plane free end deflection model was developed to simulate the forces placed on a bandage/splint construct during stabilization of a complete mid-metacarpal bone fracture. The total deflection of the model in one plane was measured following application of 3 different bandage/splint combinations including a classic, 3 layered Robert Jones Bandage (RJB) with a splint placed on the outside of the bandage (RJB-3), an RJB with splint placed after the f...
Raschka C, Feuerbach L.Using an online questionnaire, the injuries of 649 acrobats on horseback were recorded (636 female, 13 male, average age 20.8 years, average sports time 12.1 years). 64% of the athletes practised their sport in the upper and 34% in the lower performance classes. 62.7% of the athletes hurt themselves on vaulting at least once during their sports time. Most injuries occured at the lower limbs (57.5%), particularly on foot (31.2%) and knee (22.2%). At the upper limbs (26.1%), injuries were most often registered at hands (8.4%) and shoulders (6.0%). 16.4% of the athletes hurt themselves on trunk, ...
Evans PM, Armour MD, Dubielzig RR. To describe the gross and histopathological ocular findings in a horse following suspected lightning injury. Methods: The eyes of a 2-year-old thoroughbred gelding were clinically and histopathologically evaluated following a severe lightning storm following euthanasia because of visual impairment. Results: Severe corneal edema and hydrops were noted clinically oculus dexter. Indirect ophthalmoscopy revealed bilateral symmetrical raised hyporeflective peripapillary geographic lesions. Histopathologic evaluation revealed corneal edema in the right eye with normal corneal endothelium...
Braun S, Lafrenz R.In recent years extracorporeal shock wave therapy (ESWT) is used in veterinary medicine especially in equine orthopedics. Different ESWT generators are commonly used in equine medicine with varying energy density and depth of penetration. The presented case report described the treatment of a ligamentum nuchae calcification with focused extracorporeal shock wave therapy with SONOCUR Plus generator combined with SONOLINE Prima ultrasound. Negligible adverse effects, the non-invasive character of the treatment, the time-saving therapy, and the positive results make the focused extracorporeal sho...
Mizobe F, Takahashi Y, Kusano K.Jockey safety is an important subject from a welfare perspective and public perception. This is the first retrospective case-control study that aims to identify risk factors associated with jockey falls (JF) in Thoroughbred jump races held by the Japan Racing Association (JRA). JF in 17,459 maiden-class race starts at eight racecourses from 2003 to 2017 were retrospectively reviewed. Data were extracted from a database and official accident reports maintained by the JRA. Thirteen possible risk factors were evaluated using multivariable logistic regression to identify those that were significan...
Wulster KB.This article discusses the basis of image formation of radiography, scintigraphy, PET, computed tomography (fan beam and cone beam), and magnetic resonance as it relates to imaging of musculoskeletal injury in the sport horse. The benefits and drawbacks of each modality are discussed with particular emphasis on sensitivity, specificity, and accuracy of identification of subchondral bone injury. Examples of straightforward as well as confounding lesions are provided, emphasizing the need for appropriate clinical workup and diagnostic analgesia, where appropriate.
Riddell LP, Yoshimura S, MacKay AV, Wilson DG.A 17-year-old Quarter horse mare was presented because of traumatic luxation of the fifth sacral and first coccygeal vertebrae resulting in loss of sensation, motor function, and perfusion of the tail. The case was complicated by an associated tail head hematoma. Due to the severity of the injury, tail amputation was performed at the level of the luxation. Tail amputations in horses at the sacrococcygeal junction following a suspected tail pull injury are infrequently reported in the literature. . Une jument Quarter horse âgée de 17 ans fut présentée pour cause de luxation traumatique de l...
Riley CB, Padalino B, Rogers CW, Thompson KR.There is an increased understanding of shared human-animal risk in terms of "one welfare", whereby when animals are at risk, so are people, so preventing injury to one species may also prevent injury to the other. Because transport-related injuries to horses are common, the authors considered this paradigm to study road equine transport-related injuries to humans in New Zealand. The aim was to determine their frequency and associated factors by distributing a survey to horse industry participants through industry organisations asking about their horse activities, road transport experiences, an...
Lamb CR.Arthrography, tenography, and fistulography (or sinography) can provide additional information about the soft-tissue components of joints, tendon sheaths, and draining tracts, respectively. Arthrography is a valuable aid in the diagnosis of synovial masses, such as villonodular synovitis, and osteochondrosis. Tenography is particularly useful in evaluating chronic tendon sheath distention. Fistulography is an effective means of identifying acute traumatic damage to synovial structures and determining the cause and extent of draining tracts.
Meghoufel A, Cloutier G, Crevier-Denoix N, de Guise JA.The fiber bundle density (FBD) calculated from ultrasound B-scan images of the equine superficial digital flexor tendon (SDFT) can serve as an objective measurement to characterize the three metacarpal sites of normal SDFTs, and also to discriminate a healthy SDFT from an injured one. In this paper, we propose a shock filter algorithm for the thinning of hyper-echoic structures observed in B-scan images of the SDFT. This algorithm is further enhanced by applying closing morphological operations on filtered images to facilitate extraction and quantification of fiber bundle fascicles. The mean F...
Baccarin RY, Martins EA, Hagen SC, Silva LC.A controlled study was designed in order to evaluate the effects of medial patellar desmotomy (MPD), combined with exercise restriction, on clinically and radiographically normal femoropatellar joints, and to identify the patellar instability by radiographic examination. MPD was performed on the right hind limb and the horses were rested for 120 days. Both hind limbs were radiographed before surgery and at 15, 30, 60, 90, and 120 days after MPD, obtaining lateromedial, flexed lateromedial, caudocranial and cranioproximal-craniodistal (skyline) views. The femorotibial and femoropatellar angles ...
Bennet ED, Parkin TDH.Racehorse training and racing schedules in many parts of the United States and Canada were interrupted or otherwise reduced during the first three to six months of 2020. This was an indirect consequence of mitigations to prevent the spread of the pandemic virus COVID-19. Data from the Equine Injury Database, a census-level survey of all race starts made in the USA and Canada, were used to analyse the incidence of fatalities in 2009-2022 among three age cohorts of racehorses within each year. There was a statistically significant increase in the incidence of musculoskeletal fatalities among 2-y...
Elghoul N, Jalal Y, Bouya A, Zine A, Jaafar A.Almost 2% of all emergency admissions involve an animal bite. While horses bite humans very rarely, their bites are mostly associated with fatalities. Herein, we report the case of a 23-year old bitten by a domestic horse causing a crush injury to his fourth finger with fracture dislocation of the proximal interphalangeal joint. The patient benefited upon arrival at the emergency department from copious irrigation with saline serum, tetanus toxoid, postexposure rabies vaccination, and prophylactic antibiotic therapy. In the operating room, surgical exploration found the ulnar digital pedicle s...
