The post-operative period in horses refers to the timeframe following surgical procedures during which the animal undergoes recovery and rehabilitation. This period involves careful monitoring and management to ensure proper healing and to minimize complications. Key aspects of the post-operative period include pain management, wound care, and the prevention of infections. Horses may require restricted movement, dietary adjustments, and regular veterinary evaluations to assess recovery progress. This page compiles peer-reviewed research studies and scholarly articles that explore the management strategies, physiological responses, and outcomes associated with the post-operative period in equine patients.
Valdez H, McMullan WC, Hobson HP, Hanselka DV.A 6-month-old Appaloosa colt had a deviation of the premaxilla and nasal septum as well as a dorsal hump of the nasal bone and maxillomandibular malocclusion. Two surgical procedures were performed 12 weeks apart to correct these anomalies. An intraoral approach and autogenous rib graft were used to correct the malocclusion and deviation of the premaxilla. Osteotomy of the nasal bone and removal of the nasal septum were performed to help correct the deviation and to facilitate free air passage through the nares.
Valdez H, Adams OR.After preliminary studies on cadavers, a surgical approach was developed for removal of the medial meniscus, offering maximal exposure and minimal trauma to the articular surfaces of the medial tibial plateau and femoral condyle. Medial meniscectomy was then performed on 10 clinically normal horses that had been given general anesthesia. Nine horses were euthanatized at intervals of 1 to 6 months, and the joints were evaluated grossly and histologically. (One horse will be examined 1 year after surgery). Medial meniscus tears were diagnosed in 5 horses; medial meniscectomy was done on 4 horses...
Rose RJ.The case histories of four horses with osteomyelitis involving the metacarpal and metatarsal bones are reviewed and the surgical treatments discussed. The horses recovered after curettage of all infected tissue and post operative drainage. The role of antibiotics in treatment is considered and reference is made to the acute treatment of deep wounds to avoid osteomyelitis.
Roberts MC, Groenendyk S.Splenectomy was successfully performed on 2 aged horses to facilitate experimental studies of Babesia equi infection. Resection of part of the 17th rib provided the most acceptable approach and avoided many complications encountered on removing part of the 16th rib.
McIlwraith CW, Fessler JF.The usefulness of inferior check ligament desmotomy as a treatment for acquired tendon contracture in horses was evaluated in 13 cases of deep digital flexor (DDF) contracture and in 3 cases of combined superficial digital flexor (SDF) and DDF contracture. In 8 of 9 cases of DDF contracture in which the dorsal surface of the hoof had not passed beyond being vertical to the ground, the surgical procedure was successful in returning the limb to a normal position and function. Compared with DDF tenotomy, inferior check ligament desmotomy was a superior treatment technique because of decreased pos...
Monin T.Physeal fractures of the tuber olecranon of 4 horses were treated, using the tension band method of compression fracture repair. A cortical bone screw and Steinmann pin were placed through the proximal fragment into the distal parent bone parallel to the palmar border of the olecranon. The tension band was placed dorsal to the Steinmann pin and anchored in a hole through the shaft of the ulna 10 cm distal to the tuber olecranon. Of the 4 foals, 2 became pasture sound, 1 is now being worked under saddle, and the 4th showed no signs of lameness 5 months after surgery.
Short CE, Brunson DB.Anesthetic management of the pleasure horse consists of the appropriate selection and administration of pre-anesthetic medications including anticholinergics, tranquilizers and narcotics followed by appropriate techniques of anesthetic induction. The anesthetic induction must vary somewhat for the pleasure horse practice since many of the procedures are completed on farms and ranches. As a result the inducing of anesthesia will frequently be with the same agent which will be used to maintain anesthesia. Noticeably will be the reduction and duration of anesthesia and surgical time. The inductio...
Böhm D, Waibl H.Of 28 fractures of the first phalanx 21 were treated with osteosynthesis; one was treated conservatively. 2 to 4 compression screws have been applied, while the distal part of the limb was immobilized by a light cast bandage for 8 days. The implants were removed 2 to 3 months post operationem. All patients are again used in sports.
Henry RW, Diesem CD, Hunter MA, Rankin JS.Eleven ponies were used to perfect a surgical approach to the brachial plexus that would offer maximal exposure to the plexus, with minimal trauma. One pony was euthanatized to determine whether surgical exposure to the plexus was feasible. By approaching the plexus from the prescapular region, the only muscle that was found necessary to incise was the cutaneus omobrachialis. The rest of the procedure required only blunt dissection. In the other 10 ponies, the wounds healed by first intention, and the gait was not affected by the surgery.
Huskamp B.The paper considers the general principles of intestinal surgery in the horse and illustrates a theatre layout suitable for this purpose. The problems of locating and reducing obstructions of the small and large intestine are discussed, with particular emphasis on incarcerations of the small bowel and the techniques of jejunal and ileal re-implantation after bowel resection.
Meek DG, Dickinson EO.An illustrated approach to the medial aspect of the equine fetlock joint is described, whereby the collateral ligaments are transected. This approach is suggested as a possible technique for metatarsal or metacarpal bone fracture repair by retrograde pinning, arthrodesis of the fetlock joint and other joint and sesamoid bone surgery. The histological evidence of satisfactory healing is presented and the advantages and disadvantages are discussed.
Cannon JH, Grant BD, Sande RD.Development of cysts in the equine paranasal sinuses is probably a congenital disease; however, signs may not appear for several years. In 4 cases, clinical signs were observed when fluid accumulation within the cysts resulted in nasal discharge or facial swelling, or when secondary infection occurred. Treatment required surgical removal of the lining membrane and other involved tissues. Postoperative care included lavage of the sinuses and systemic antibiotic therapy.
Hekmati P, Schels H.Surgical correction of corneal opacities in horses has rarely been documented in detail and is still reported to be in the experimental stage. For this reason, studies of lamellar keratoplasty were conducted on the equine eye using a modified trephine with an adjustable inside quard for grafting of identical discs from the donor and the recipient cornea. Fourteen transplantations, seven with homografts and seven with heterografts, 15 and 9 mm in diameter, were performed. Sharp-edged, vertical, and regular outlined wound margins of the graft and host are essential for good adaptation and healin...
Reinertson EL.Thirteen horses and ponies were used to evaluate an anastomotic technique utilizing a modified Gambee suture pattern. The modified Gambee technique was compared with a single-row everting technique and a double-row inverting technique. The double-row inverting technique predisposed to intestinal obstruction and resulted in minimal adhesions. The everting technique predisposed to leakage of intestinal contents and subsequent peritonitis. Adhesions were formed at the site of the anastomosis to such an extent as to jeopardize the proper position of the bowel. The technique did not cause any lumin...
Knudsen O.The paper briefly describes the percutaneous tendon splitting operation as performed in general practice and evaluates its effectiveness on the basis of races run during a 2 year follow-up period. The results are compared with similar figures for normal Standardbred trotters. A higher percentage of horses subjected to splitting of the suspensory ligament failed to remain sound long enough to run more than 10 races during the follow-up period. The percentage of horses returning to racing whose superficial flexor was operated upon was somewhat lower than the control group.
Nelson AM.Of 275 mares receiving prostaglandin F2alpha-Tham salt for its luteolytic effect upon the corpus luteum, 231 (84 per cent) exhibited signs of oestrus (range 73-95 per cent). Some mares not exhibiting overt oestrus may, nevertheless, ovulate and post-treatment rectal palpation of mares apparently failing to respond is suggested in these cases. Of 210 mares for which subsequent history was available. 104 (49.5 per cent) became pregnant from breeding at the post-treatment oestrus that immediately followed the induced regression of the corpus luteum (range 42.2-55.5 per cent). Fertility is compara...
Frankland AL, Morris PG, Spreull JS.Seven pieces of autologous skin were transplanted onto freshly created, full thickness skin defects on the limbs and back of a one-year-old, male, piebald, Shetland pony. The transplantations were completed in two operative sessions, the transplants on the left side were done in the first session and the right side in the second. The sizes of the transplants varied from 20 sq cm to 2 sq cm and their thicknesses from whole skin to very thin, split skin. Donor sites were both rumps and the right side of the neck. Six of the seven grafts and two thirds of the remaining graft, were accepted. Both ...
Hilmas DE, Gillette EL.The clinical records and follow-up data obtained over 13 years on the results of radiotherapy of spontaneous fibrous connective-tissue sarcomas in dogs, cats, and horses were reviewed. The results obtained from the treatment of fibrosarcomas and sarcoids of horses indicated that radiation administered with 60Co is important in the medical and surgical management of these tumors. Fibrous connective-tissue sarcomas in horses were radioresponsive. When radiotherapy was applied postoperatively, the probability of a 2-year cure approached 50% for all prescribed radiation doses of less than 2,000 to...
Milne DW, Turner AS, Gabel AA.In the horse, surgical approaches for plating fractures of the ulna, radius, metacarpus, tibia, and metatarsus involved a single curvilinear skin incision and incision of the superficial fascia in a manner to prevent postoperative dehiscence. The tension side of the bones, as well as location of nerves, arteries, veins, and muscles, were the major determinants in developing these approaches for atraumatic surgery and short operative time.
Denny HR.Methods of treating fractures of the olecranon in the horse are reviewed. A further 4 cases are recorded in which the fracture was treated by open reduction and fixation with a heavy duty Venable's plate placed on the caudal aspect of the ulna. Three cases had an oblique fracture through the semilunar notch; this was complicated in one by a fracture of the lateral half of the radial head which resulted in subluxation of the radio-humeral joint. The fracture of the radial head was treated by open reduction and fixation with a lag screw. The fourth case had an oblique fracture of the olecranon j...
Stashak TS, Adams OR.Autogenous bone grafts were obtained from the tuber coxae of 9 horses. The method used involved an oblique incision to expose the lateral aspect of the tuber coxae. The periosteum was incised and reflected in order to make a 5- by 2.5-cm opening in the lateral cortex for graft retrieval. The method provided good visualization, ample grafting material, and freedom from postsurgical complications.
Qin SH, Sun L, Zheng XJ.To explore the Ilizarov mini-invasive distraction technique for the treatment of severer ankle and foot deformities secondary to ischemic contracture of the leg. Methods: Based on the tension-stress low of Ilizarov, a serial of adjustable three dimensions external distractive instrument was developed in our department. From April 2002 to March 2004, 8 patients with ankle and foot deformities secondary to ischemic contracture of the leg induced by trauma and fracture were treated with the distractive instrument. Of them, 4 patient were male and 4 female, aged from 13 to 31 years with an average...
Tate LP, Newman HC, Cullen JM, Sweeney C.Laryngeal surgery in the equine is customarily and routinely performed by means of a ventral laryngotomy incision. Such procedures are usually performed under deep general anesthesia with the horse in dorsal recumbency. The objective of this work was to determine the efficacy of an endoscopic approach coupled to a Nd:YAG laser fiber in performing arytenoidectomy. Arytenoidectomy is commonly indicated in the treatment of arytenoid chondritis and in the failure of prosthetic implantation for left laryngeal hemiplegia. This preliminary study was undertaken to determine the feasibility of the endo...
Todhunter RJ, Stick JA, Slocombe RF.The effects of 3 feeding techniques on healing of a cervical esophageal mucosal resection and anastomosis were investigated in 16 horses. Horses were fed a moistened pelleted diet 1 of 3 ways: 1) per os (n = 5), 2) by nasogastric (n = 5) or 3) by esophagostomy tube (n = 6) until the 14th postoperative day. The pelleted diet was then fed orally in all horses until euthanasia on the 60th postoperative day. Immediate postoperative feeding per os was unsatisfactory, as only 2 of 5 horses survived in this group. Endoscopic evaluation revealed that mucosal dehiscence of varying degrees occurred, wit...
Martinez-Lopez J, Brown JA, Werre SR.To compare the prevalence of incisional complications after skin closure with n-butyl cyanoacrylate (NBC) or stainless-steel skin staples (SS) after ventral midline celiotomy for colic surgery in the horse. Methods: Retrospective study (2014-2018). Methods: Two hundred eighteen horses. Methods: Medical records of horses that underwent exploratory celiotomy for colic were included when the skin was closed with NBC or SS and the horse survived ≥15 days after surgery. Records and a follow-up questionnaire were used to determine in-hospital and posthospital discharge incisional complications. ...
Rose RJ, Taylor BJ, Bellenger CR.The technique of internal fixation of intra-articular fractures of the third phalanx using lag screw interfragmentary compression is described. Three cases are discussed and the successful treatment of infection and osteomyelitis described in one of them. Despite this potential complication internal fixation offers a better prognosis and also a more rapid return to work than non-operative treatments.
Monin T.Physeal fractures of the tuber olecranon of 4 horses were treated, using the tension band method of compression fracture repair. A cortical bone screw and Steinmann pin were placed through the proximal fragment into the distal parent bone parallel to the palmar border of the olecranon. The tension band was placed dorsal to the Steinmann pin and anchored in a hole through the shaft of the ulna 10 cm distal to the tuber olecranon. Of the 4 foals, 2 became pasture sound, 1 is now being worked under saddle, and the 4th showed no signs of lameness 5 months after surgery.
Charman RE, Vasey JR.Carpal flexural deformities (CFD) are frequently encountered in the horse, with both congenital and acquired forms described. The success of surgical correction of CFD, both in terms of the ability to achieve a straight palmar carpal angle and the impact on future athletic performance, requires further investigation. Objective: To report the surgical management and outcome of treatment of flexural deformity of the carpus in 72 horses up to 12 months of age. Methods: Information was obtained from the medical records of horses surgically treated for CFD and through follow-up contact with owners....
Moll HD, Schumacher J, Dabareiner RM, Slone DE.Three horses underwent exploratory celiotomy because of signs of acute abdominal pain. At surgery, all horses were diagnosed as having left dorsal displacement of the large colon. Each surgery was complicated by fibrous adhesions of the spleen to the body wall. All horses had previously undergone abdominal surgery for colic. In these cases, it appeared that the left large colon displaced cranially and then entered the renosplenic space from a cranial to caudal direction. Adhesions of the spleen to the body wall would prevent correction of left dorsal displacement of the large colon by the roll...
Hofmeister S, Becker M, Böckenhoff G.Objective to this field study was to find an alternative to rolling a colic patient with left dorsal displacement under general anesthesia. For that purpose a total of 49 horses with a complete nephrosplenic entrapment out of 542 colic patients presented at the Tierklinik Kerken in 1996 were retrospectively evaluated. Having performed a preliminary colic examination and initial treatment if needed, horses which did not undergo surgery immediately where left loose in a small sized arena to move and roll themselves under observation. According to the results of further exams, horses were left in...
Haralambus RM, Werren C, Brehm W, Tessier C.To report use of a pinless external fixator (PEF) for unilateral mandibular fractures in 9 equids. Methods: Case series. Methods: Equids (n=9) with unilateral mandibular fractures. Methods: All fractures were stabilized with the AO/ASIF PEF using a minimum of 4 clamps, under general anesthesia. Fracture configuration, complications, outcome, and owner satisfaction were evaluated. Results: All fractures were stabilized; 2 equids were euthanatized; 1 because of an inability to stand after surgery and 1 because of owner decision after PEF dislodgement. Seven repairs healed with good outcome and o...
Boles C.Emergency equine abdominal surgery is easiest and most efficiently carried out with a team of surgeons. The surgical site should be as protected as possible by the use of sterile drapes and wound protectors. A ventral midline laparotomy incision has been found to be the most convenient approach to most equine intestinal obstructions. A standing laparotomy through the left paralumbar fossa gives adequate exposure for exploration of the abdomen and is, therefore, useful as a diagnostic tool. Horses tolerate having both ventral midline and left paralumbar laparotomy incisions well. If the cause o...
Hurcombe SD, Roessner HA, Klein CE, Engiles JB, Hopster K.Jejunal vascular ligation is an essential step in performing jejunojejunostomy. Hand sewn ligation is typically used and can increase operative time with long sections of bowel to be removed. Nylon cable ties (NCT) have been used for vascular ligation in horses but are yet to be investigated for application on the mesenteric vasculature of the gastrointestinal tract. Our objective was to evaluate the efficacy and short-term safety of NCT jejunal mesenteric vessel ligation in healthy horses. Eight healthy adult horses underwent midline celiotomy. A segment of jejunal mesentery was identified (â...
Dubois BB, Rodgerson DH.To describe a drilling technique for hemiepiphysiodesis of the distal lateral metacarpal physis and report the outcome of treated foals. Methods: Retrospective case series. Methods: Eleven thoroughbred foals. Methods: While horses were under general anesthesia, the lateral aspect of the distal metacarpal physis was approached through a single small incision by using a power drill. The drill bit was placed at the level of the physis under radiographic guidance. A 4.5-mm drill bit was passed several times through the lateral growth plate to remove the cartilage in a fan-like pattern. Postoperati...
Hunt RJ, Allen D, Baxter GM, Jackman BR, Parks AH.Deep digital flexor tendon transection at the mid-metacarpus was performed in 20 horses with severe acute or chronic laminitis that was not responsive to conventional treatment. Sixteen horses improved within 72 hours, one horse worsened, and two horses were unaffected by the surgery. Eleven horses survived less than 1 month after surgery and six horses survived longer than 6 months. Three horses surviving longer than 6 months have remained lame and no horse has returned to athletic performance. Transection of the deep digital flexor tendon at the mid-metacarpus may decrease the pain associate...
McCoy AM, Goodrich LR.Annular ligament desmotomy is commonly performed in horses with chronic tenosynovitis. Previously reported tenoscopic techniques have limitations related to haemorrhage and awkward instrumentation. Radiofrequency (RF) energy affords precision and excellent haemostasis and may be a good alternative to sharp transection of the annular ligament in horses. Objective: To describe a technique for using a RF probe for tenoscopic-guided annular ligament desmotomy and to report the clinical outcome of horses in which it was performed. Methods: Cadaver specimens (n = 14) and live horses undergoing unrel...
Easter JL, Hague BA, Brumbaugh GW, Nguyen J, Chaffin MK, Honnas CM, Kemper DL.To evaluate the effect of peritoneal lavage on pharmacokinetics of gentamicin sulfate in healthy horses after experimental celiotomy. Methods: 13 clinically normal horses. Methods: Horses were randomly assigned to control or experimental groups. All horses received gentamicin (6.6 mg/kg of body weight, IV, q 24 h) before surgery, underwent experimental abdominal surgery, and had abdominal drains placed percutaneously. Horses of the experimental group received postoperative peritoneal lavage; horses of the control group did not receive peritoneal lavage. The day after surgery, 24 hours after th...
Bristol DG, Cullen J.Six animals were used to compare simple interrupted, simple continuous, and stapled techniques for end-to-end rotated small colon anastomoses. Three ponies were evaluated three days after surgery for adhesion formation and luminal diameter at each anastomosis site. Two ponies and one horse were evaluated 14 days after surgery for adhesion formation. All anastomosis sites were examined histologically for alignment of tissue planes, and evidence of inflammation. No single technique was superior in all areas examined. While only three of the nine anastomoses had mild fibrinous adhesions at three ...
Fessler JF.Major surgery for wounds of the foot, compared with other parts of the body, requires a more detailed preparation and a more persistent aftercare. To approach severe hoof wounds with a routine applicable to drainage of a subsolar abscess is doomed to failure! Yet, in dealing with referral cases of hoof wounds, particularly those that have become chronic, the author has observed that the principles have been ignored and/or the routines inadequate. The hoof has a suitable capacity to heal, with complete reformation of hoof structures, if a healing environment is maintained for a long enough peri...
Ravanetti P, Hamon M, Lechartier A, Zucca E.Surgical repair of unicortical fractures of the distal condyles of the third metacarpal/metatarsal bones (MCIII/MTIII) has been described. In the present case, a bioabsorbable screw was used to stabilize a unicortical fracture in the palmar aspect of the medial condyle of MCIII in a National Hunt Thoroughbred racehorse. The clinical, radiographic, and magnetic resonance imaging findings before and after surgery were recorded. Eighteen weeks after surgery, the lameness had resolved and the bone surrounding the fracture had recovered its normal architecture. One year after surgery, the horse was...
Rigert S, Geyer H, Kummer M.The following case report describes the treatment of canker in a 14 years old warmblood gelding. The horse showed the typical appearance with caseous surface and early detachment of the superficial horn layers. The histological results show a severe degradation in the germinal layer of the epidermis of the frog. Surgical therapy under general anaesthesia was performed. On all limbs a tourniquet was applied and all abnormal tissue in the region of the frog and also the subdermal tissue underneath were removed. Postoperatively the horse was treated with hoof bandages for 2 weeks. Treatment plate...
Changoor A, Hurtig MB, John Runciman R.Multiple osteochondral grafts can be used to resurface large joint defects in both humans and horses. In humans, immediate postoperative weight bearing can be prevented, however in the equine, it is unavoidable. Early weight bearing can create detrimental graft micromotion. The aim of this study was to investigate the role of a bioresorbable cement in improving the initial stability of multiple osteochondral graft repairs of large subchondral cystic lesions in the horse. Configurations employed for filling a 20mm diameter cylindrical defect included: (A) twelve 4.5mm diameter grafts with cemen...
Vidović A, Jansen D.The first part of this case report describes the surgical treatment of a unilateral mandibular fracture in the standing horse by using a fixateur type I. By the time of implant removal, the fracture had completely healed. However, during implant removal, an implant failure of 2 of the 4 implants occurred with fragments remaining in the bone. The second part of the report focuses on the development of a special surgical instrument that was designed for removal of the implant fragments. Furthermore, the surgical method allowing the entire extirpation of the fragments within a second surgery is d...
Winberg FG, Pettersson H.Twenty horses with central and third tarsal bone slab fractures, were treated internal fixation. Eighteen of the 20 cases were Standardbred trotters, one was a Thoroughbred racehorse and one a Swedish Warmblood. The central tarsal bone (CT) was involved in 12 cases and the third tarsal bone (T3) in 8 cases. The fractures were treated by lag screw fixation with one (18 cases) or two (2 cases) 3.5 or 4.5 mm cortical screws. Horses were confined to stall rest for one month and then put on a gradually increasing exercise programme. Convalescence time was 3-8 months until the fracture had healed an...
Boone LH, Epstein K, Cremer J, Rogers A, Foutz T, Quandt J, Howerth E, Mueller PO.To compare tensile strength, failure location, and histologic features after acute repeat celiotomy through a ventral median (RVM) or a right ventral paramedian (RVP) celiotomy in horses. Methods: Ex vivo experimental study. Methods: Adult horses (N = 18). Methods: Twelve adult horses had original ventral median (OVM) celiotomy. Repeat celiotomy was performed 72 hours postoperatively through the original ventral median (RVM, N = 6) or a RVP (N = 6) celiotomy. Celiotomies were scored daily for edema, drainage, and dehiscence. Fourteen days after repeat celiotomy, horses were eutha...
Maekawa Y, Sakamoto T, Umezu K, Ohashi N, Harada Y, Yasukochi S, Takigiku K, Takei K, Nakano Y, Inoue N, Otagiri T, Hashida Y.We report a female infant with acute coronary syndrome after Aubert-Imai modification for transposition of the great arteries. Two months postoperatively, she visited the emergency room because of perspiration and tachypnea. She was diagnosed with acute coronary syndrome by blood chemistry examination. Cardiac catheterization revealed Aubert route stenosis, and emergency operation was performed. The lumen around the aortopulmonary window was almost totally occluded by fibrous tissue extending from the equine pericardial patch. This fibrous tissue was completely resected and the aortopulmonary ...
