Lameness attributable to osteochondral fragmentation of the plantar aspect of the proximal phalanx in horses: 19 cases (1981-1985).

Osteochondral fragmentation of the plantar aspect of the proximal phalanx was diagnosed as a cause of hind limb lameness in 19 horses. The lameness was evident at the upper levels of the horses' performance capabilities, and was isolated to the metatarsophalangeal joints by use of intra-articular or regional anesthesia. Fragments were surgically removed from 10 horses that later returned to full use. Seven horses were treated intra-articularly with polysulfated glycosaminoglycans or corticosteroids; only one horse was able to return to full use. One horse was retired from work at the time of diagnosis. Surgery appeared to be the most effective treatment for osteochondral fragmentation of the plantar aspect of the proximal phalanx, although medical treatment combined with a decrease in the horses' expected performance also was believed to be useful.

Chronic nongranulomatous enteritis in seven horses.

Chronic nongranulomatous intestinal inflammation was found during laparotomy in 7 horses. The clinical signs consisted of recurrent abdominal pain in all horses. Anti-inflammatory agents (corticosteroidal and nonsteroidal agents) appeared to be effective for controlling the signs. Surgical removal of the involved intestine also was effective. Nonocclusive or temporary mesenteric ischemia was proposed as a cause of the intestinal lesions.

Axial sesamoid injuries associated with lateral condylar fractures in horses.

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.

Intussusception associated with Anoplocephala perfoliata infection in five horses.

Intussusception associated with Anoplocephala perfoliata infection was found in 5 horses. The unusual types of intussusception and the presence of tapeworms at the leading edge of the intussuscipiens suggested tapeworms as the cause of the problem. Lesions attributable to tapeworm attachment on the mucosa were found to fit a mechanical model of intussusception. Treatment of two of the horses and some of their pasturemates with pyrantel pamoate caused elimination of intact tapeworms.

Volvulus of the large colon in the horse.

Volvulus of the large colon was diagnosed at surgery in 25 horses during a 4-year period. Two horses had a recurrence of the condition after successful correction. Mucosal necrosis was found to be a grave prognostic sign, as it was a consistent finding in horses that died at the time of surgery. Long-term colon dysfunction was not clinically evident in surviving horses.

Equine villonodularsynovitis: a case survey.

Nineteen cases of villonodular synovitis as identified in 14 horses are presented. Physical and radiographic findings are discussed and the surgical correction described. Case histories indicate that surgical extirpation of the lesion is corrective and that rest without surgical intervention is ineffective. Radiation therapy following surgery does not appear to be necessary.

Bypass surgery for the treatment of small intestinal ileus in the horse. A report of three cases.

The medical management of three horses with simple and strangulating small intestinal obstructions was unsuccessful and was therefore supported by surgical bypasses. Jejunocecostomies were used to treat horses with postoperative paralytic ileus that was unresponsive to medical management. These horses had abdominal pain, gastric distention, heart rate elevations greater than 60/minute, and small intestinal distention on rectal palpation. Two horses experienced weight loss which responded to bypass removal. The bypass effectively decreased the need for intravenous fluid administration and repeated nasogastric intubation.
