ABSTRACT
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.

Supraspinatus and infraspinatus muscle paralysis with atrophy was treated by partial osteotomy of the scapula, deep to the suprascapular nerve. The horses had various gait abnormalities, which were corrected by the surgery, but regeneration of the muscles varied from partial to complete, depending on the duration of the condition and the degree of atrophy before surgery.

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 and 1 horse was rested. Removal of the medial meniscus was considered feasible in the horse, but the resulting degree of locomotor impairment varies. Prognosis for surgical removal of the medial meniscus was considered to be guarded to good.

Of 124 horses determined to have navicular disease during a 5-year period, 6 had clinical and radiographic signs of the disease in both hindlimbs. These 6 were all castrated males, ranging in age from 3 to 12 years, and were used for work of similar nature: roping, cutting, and pleasure. Treatment consisted of posterior digital neurectomy and corrective shoeing in 2 cases, posterior digital neurectomy alone in 2 cases, and corrective shoeing alone in 2 cases. Following treatment, lameness subsided, and all 6 horses were returned to full use.

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.
