Surgery for horses encompasses a range of procedures performed to diagnose, treat, or manage various medical conditions. These procedures may involve soft tissue or orthopedic interventions and require specialized techniques to accommodate the unique anatomical and physiological characteristics of equines. Common surgical procedures in horses include colic surgery, fracture repair, and arthroscopy. The success of equine surgery depends on numerous factors, including the type of procedure, the horse's overall health, and post-operative care. This page compiles peer-reviewed research studies and scholarly articles that explore surgical techniques, outcomes, and advancements in equine surgical practices.
Smith BP, Reina-Guerra M, Hardy AJ.Feces from 1,451 horses entering a veterinary hospital over a 13-month period were cultured for salmonella. A total of 46 horses (3.2%) yielded 1 or more salmonella-positive fecal cultures. Twenty horses were found to be excreting salmonella in the feces on admission, and 5 of these later had severe diarrhea associated with enteric salmonellosis. Abdominal surgery and other severe stresses were associated with all cases of severe enteric salmonellosis. Serotypes of salmonella isolated included Salmonella agona (15), S anatum (14), S typhimurium (7), S typhimurium var copenhagen (4), S infantis...
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.
Smith DF.The pathophysiology, diagnostic evaluation and medical management of the horse with intestinal obstruction is outlined. Emphasis is on early and accurate determination of the need for surgery and on providing optimal preoperative medical support.
Firth EC.The findings in 6 experimental and 1 natural case of Horner's Syndrome (HS) are presented. The experimental cases were induced by unilateral surgical section of the cervical sympathetic trunk in the middle third of the neck. The naturally occurring case was seen in a 17 year old gelding with a mediastinal tumour. The signs of HS in these horses included ptosis, miosis, enophthalmos, hemilateral sweating and temperature increase of the face and cranial cervical region on the affected side. The intensity of these signs was variable between and within animals. Miosis, enophthalmos and temperature...
Strömberg B, Rejnö S.The clinical and radiologic features of osteochondritis dissecans in the knee and hock joint of horses are described. The material includes 91 horses, of which 43 had the lesion in one or both knee joints, and 48 in one or both hock joints. It was found that osteochondritis dissecans of the knee joint was more common than the one in the hock joint in thoroughbreds and halfbreds, while the lesion in the hock joint was most common in standardbred trotters. In the knee the lesion was most often located to the lateral trochlear ridge. In the hock joint the predilection site was the intermediate ri...
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...
Mills JH, Fretz PB, Clark EG, Ganjam VK.An ovarian neoplasm measuring 10 by 8 by 6 cm was surgically removed from a 14-year-old Appaloosa mare. For 2 years prior to surgery, the mare had manifested marked behavioral changes, becoming aggressive toward other broodmares. Histologically, the tumor was found to be an arrhenoblastoma. Preoperative endocrinologic findings (high serum testosterone and low serum estradiol concentrations) supported the diagnosis.
Bennett D, Campbell JR, Rawlinson JR.Two cases of coxofemoral luxation complicated by upward fixation of the patella are described in the pony. Clinical signs included outward rotation of the stifle and foot and inward rotation of the hock with the stifle and hock joints fixed in extension. One case was treated by performing a medial patellar desmotomy with a resultant significant improvement in locomotion. Other cases of hip luxation reported in the literature, some complicated by upward patellar fixation, are reviewed. Hip luxation is principally seen in ponies and it is suggested that upward fixation of the patella occurring i...
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.
Mason TA, Maclean AA.Two cases of osteochondrosis dissecans of the head of the humerus in foals are described. The lesions were gross compared with those seen in dogs. Arthrotomy and curettage of the affected area resulted in marked clinical improvement.
Strömberg B, Tufvesson G.Four autologous tendon grafting techniques, bipedicle, pedicle and free grafts of the deep digital flexor tendon and free grafts from the lateral digital extensor tendon were described. The vascularization and remodelling of the transplant and the reactions in the donor, as well as the recipient tendon, were studied by means of microangiographic and histochemical methods. The results indicated that regardless of the technique used the grafts were revascularized and replaced by a highly orientated and organized tendon. The use of free grafts may therefore be worthwhile in treatment of severe te...
Mason TA.Seven cases of chronic tenosynovitis affecting the extensor carpi radialis or lateral digital extensor tendon and their sheaths are described. All cases were chronic and in 4 of the cases previous treatment by drainage and local corticosteroid injection had been ineffective. Surgical exploration of 6 cases demonstrated a distinct lesion and specific surgical treatment was carried out.
Scott EA, Snoy P, Prasse KW, Hoffman PE, Thrall DE.A yearling Quarter Horse colt was examined because of intermittent esophageal obstruction. A soft tissue mass was palpated in the cervical portion of the esophagus. Plain and contrast radiography and esophagoscopy were utilized to confirm the location of the lesion in the esophageal wall. Surgical exploration and removal of the mass was performed through a ventral midline cervical incision. Histologically, the mass was a keratinizing squamous epithelial inclusion cyst.
Gay CC, Carter J, McCarthy M, Mason TA, Christie BA, Reynolds WT, Smyth B.Indirect arterial blood pressure was determined on 33 horses prior to surgical intervention for the diagnosis and/or correction of acute abdominal disorders and a relationship between low systolic blood pressure and non-survival was established. It is suggested that blood pressure determination should be used to augment other methods of clinical and laboratory examination in cases of equine colic.
Smith JS, Mayhew IG.The sympathetic nervous innervation of the head was surgically transected in the horse, cow, sheep and goat. The site of transection was preganglionic in all 4 species and ganglionic-postganglionic in 2 additional horses. The Horner's syndrome, manifested as a result of the iatrogenic lesion, varied with the species. Ptosis was the most constant sign in all species. Unilateral sweating over the face and proximal neck, particularly at the base of the ear, was the most prominent feature in the horse. The cow revealed distension of vasculature and cutaneous heat of the pinna, and a reduced produc...
Bras GE, Kersjes AW.Comparative studies were done on healing of the wound following laparotomy through the ventral wall of the abdomen (paramedian incision or in the linea alba) in seventy horses and following surgical treatment of umbilical hernia in eighty-five (young) horses, in which perlon, (chromic) catgut, stainless steel wire and polyglycollic acid were used as suture material. Though with some reserve, as the study was concerned with the comparison of findings in clinical cases in which a number of conditions may vary, it is concluded that steel wire and polyglycollic acid are preferable to perlon and (c...
Hoffer RE, Barber SM, Kallfelz FA, Petro SP.Esophageal patch grafting, using the sternocephalicus muscle, was used for treatment of cervical esophageal stricture in a mare. The mare was maintained during the initial healing phase by total parenteral nutrition.
Boles CL, Kohn CW.OF 207 horses with colic seen over a 36-month period, 10 were determined to have impaction colic caused by ingestion of synthetic fencing material. In 6 cases, there was history of exposure to rubberized fencing products. All horses affected were less than or equal to 3 years of age, had signs of mild to moderate abdominal pain, and were unresponsive to usual symptomatic therapy. At surgery, each horse was found to have an impaction involving the distal right dorsal colon, transverse colon, or small colon, and in some cases, all 3 bowel segments. In 9 cases, the involved segment of bowel could...
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.
O'Brien T, Hunt RJ.In all surgeries with the patient standing under chemical and physical restraint, patient compliance is of the utmost importance. All fractures of the third metacarpal or metatarsal condyles and sagittal fracture of the first phalanx are not amenable to internal fixation with the horse standing, and young unhandled horses may not have a suitable disposition for standing surgical treatment of septic pedal osteitis, or implantation and removal of transphyseal screws. Previous operator experience in performing the procedure or technique under general anesthesia is beneficial. Appreciation of appr...
Smanik LE, Stefanovski D, Reilly PT, Richardson DW.Type II distal phalanx (P3) fractures are a well-described cause of lameness in horses.

Cramp P, Derksen FJ, Stick JA, de Feijter-Rupp H, Elvin NG, Hauptman J, Robinson NE.The nerve-muscle pedicle graft technique is a treatment for recurrent laryngeal neuropathy (RLN), but the optimal placement of the pedicles within the cricoarytenoideus dorsalis (CAD) muscle is unknown. Objective: The magnitude and direction of force placed on the muscular process of the left arytenoid cartilage affects the magnitude of laryngeal abduction. Methods: Five larynges were harvested from cadavers. Using increments of 0.98 N, a dead-weight force generator applied a force of 0-14.7 N for 1 min each to the left muscular process at 0, 10, 20, 30, 40, 50, 60 and 70 degrees angles. The r...
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...
Trotter GW.Numerous conditions, including trauma, infection, neoplasia, and developmental problems, can affect the paranasal sinuses. Successful resolution of these problems is predicated upon a thorough diagnostic workup to ensure the most accurate presumptive diagnosis. Surgical intervention is enhanced by using approaches that allow wide access to sinus compartments. Rigorous postoperative management is also important to a successful outcome.

Hall NP, Heaton KT, Farnsworth KD, Ragle CA.This report evaluates the use of 4.5- and 5.5-mm cannulated drill bits for articular cartilage removal from the proximal interphalangeal joints of equine cadaver limbs. Limbs from 8 equine cadavers, all with normal proximal interphalangeal joints. Proximal interphalangeal joints of 32 limbs from 8 equine cadavers were drilled using either 4.5- or 5.5-mm cannulated drill bits. Pastern joints were then disarticulated, and intra-articular drilling was evaluated by visual inspection. Post-drilling evaluation revealed complete intra-articular drilling occurred in all 32 joints. Canulated 4.5- and 5...
Ross MW, Stephens PR, Reimer JM.A 9-year-old pregnant Standardbred broodmare was evaluated for signs of mild abdominal pain, failure to defecate, and mild abdominal distention. Rectal examination revealed the leading edge of a small colon intussusception, and peritoneal fluid analysis indicated suppurative peritonitis. Surgical management, including reduction of the intussusception and small colon resection with end-to-end anastomosis, resulted in successful outcome (1-year follow-up evaluation). Postoperative complications including dehiscence of the ventral midline surgical incision and simple obstruction at the anastomosi...
Grenager NS, Durham MG.This report describes the use of ultrasound to diagnose right dorsal displacement of the large colon (RDDLC) in 13 horses prior to surgery. Horses had ultrasonographic examinations performed of the right lateroventral aspect of the abdomen upon admission to the hospital with a 2-5 MHz broadband curvilinear sector scanning transducer after alcohol was used to wet the hair. First, the caecal vessels were identified in the right flank and followed medially and cranially. Next, each intercostal space, from caudal to cranial, was scanned from dorsal to ventral evaluating for abnormally-located mese...
Loinaz RJ, Boutros CP, Rakestraw PC, Taylor TS.To report a laryngotomy approach for the removal of the nasal septum in adult horses. Methods: Descriptive study. Methods: Horses (n = 10). Methods: Near-total resection of the nasal septum was made using a modification of a previously reported 3-wire technique using a trephination approach and a 2-wire technique using a laryngotomy approach. Surgical time, ease of technique, complications, and outcome were recorded. At 45 days, horses were euthanatized and septal measurements made. Results: Near-total resection of the nasal septum was accomplished with both techniques without complications. I...
Lumsden JM, Caron JP, Stickle RL.Bilateral radiographically persistent proximal third metatarsal physes and concurrent cuboidal bone immaturity were identified in a foal. Repair of a Salter type-II fracture of the left proximal third metatarsal physis was accomplished by use of lag screw fixation. A 6-day-old Arabian foal, intended for use as a show horse, was referred because of severe unilateral hind limb lameness and valgus deformity. A Salter type-II fracture of the proximal portion of the third metacarpal bone was identified radiographically and repaired by use of cancellous lag screws. The fractured limb was further sup...
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...
Freeman DE, Richardson DW, Tulleners EP, Orsini JA, Donawick WJ, Madison JB, Ross MW, Beroza GA.Loop colostomy was performed in 10 horses as treatment for grade-III rectal tears (n = 6 horses), small-colon infarction (n = 2 horses), perirectal abscess and stenosis (n = 1 horse), and small-colon stricture (n = 1 horse). In 7 horses, the colostomy was constructed through a single incision low in the left flank, with closure of the incision around the stoma (single-incision technique). In 3 horses, 2 of which had colostomy performed as a standing procedure, the selected segment of small colon was placed from a flank incision into a separate, small incision low in the left flank (double-inci...
Stick JA, Borg LA, Nickels FA, Peloso JG, Perau DL.An osteochondral fragment was removed from the caudal pouch of the lateral femorotibial joint in a 2-year-old Trakehner colt by use of arthroscopic surgery and a lateral approach. The approach to this aspect of the femorotibial joints was developed in another horse. The fragment was not attached and resembled an osteochondritis dissecans lesion. The intermittent lameness associated with the fragment resolved after surgical removal. A positive response to diagnostic anesthesia of the femorotibial joint in the absence of a confirmed diagnosis (following radiographic and arthroscopic evaluations ...
Schumacher J, Crossland LE.Primary paranasal sinusitis, complicated by inspissated purulent exudate in a ventral conchal sinus, was diagnosed in 3 horses. Partial nasal obstruction, caused by axial deviation of the ventral concha, was detected endoscopically in 2 of the horses. A mass, dorsal to the maxillary molars, was detected via a lateral radiographic view of the skull of 3 horses and on the dorsoventral view of 1 of the horses. Inspissated purulent exudate was removed from the ventral conchal sinus of the horses via trephination of the conchofrontal sinus and penetration of the caudal wall of the ventral conchal s...
Kraus BM, Richardson DW, Nunamaker DM, Ross MW.To report the outcome of surgical treatment of comminuted fractures of the proximal phalanx in horses. Methods: Retrospective study. Methods: 64 horses. Methods: Medical records and radiographs were reviewed to obtain information regarding signalment, fracture classification, and treatment.

Two horses were euthanatized immediately. Fractures of the proximal phalanx in 36 horses were repaired with open reducti...
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...

Gloria A, Carluccio A, Petrizzi L, Noto F, Contri A.Equine spermatozoa from the cauda epididymis were previously collected and frozen, and the fertility was assessed. Most studies were performed on healthy stallions that had undergone routine castration or on the epididymis collected at the abattoir, but there are no studies on the quality of epididymal semen in subjects which have died from colic or which underwent intensive care. The present study was designed to verify whether a severe illness could affect epididymal semen quality and freezability in the stallion. Therefore, epididymal semen characteristics during the freezing process in sta...

Objective: To evaluate subject details, history, clinical findings and outcome of type 1b olecranon fractures in a large group of horses treated by tension band plate fixation. Methods: Medical records of 77 horses diagnosed with an olecranon fracture were reviewed. Twenty-four horses (31%) were classified as having type 1b olecranon fractures. Clinical details and follow-up results (4-128 months post operatively) were recorded. Results: Treatment includ...
Van Hoogmoed L, Snyder JR.Four horses were evaluated for clinical signs consistent with small intestinal disease. During exploratory surgery, primary hematomas in the mesentery were found in 2 horses. The third horse developed a hematoma secondary to a mesenteric rent, whereas in the fourth horse, a hematoma developed secondary to strangulation of the bowel by a mesenteric lipoma. Two horses were euthanatized at surgery, because the extensive nature of the hematoma precluded ligation and there was substantial risk of continued hemorrhage postoperatively. The remaining horses recovered from surgery but developed complic...
Williams TL, Mochal-King C, Rude BJ, Weed BC, Nicodemus MC.Cecal and ileal cannulations have previously been used to determine equine digestibility and define gastrointestinal physiology. However, research has been limited to specific portions of the equine digestive tract lacking utilization of dual cannulations. The purpose of this study was to develop and implement surgical and preoperative and postoperative procedures for cannulation of dual sections, ileum and cecum, of the equine digestive tract including development of recommendations for addressing postsurgery complications. A total of 8 ponies went through surgical procedures for the placemen...
