title: Excision of femoral head and neck for treatment of coxofemoral degenerative joint disease in a rhesus macaque (Macaca mulatta).
abstract: Nonhuman primates are a valuable model for osteoarthritis. Osteoarthritis has been extensively studied in nonhuman primates in both naturally occurring and induced disease states. However, little published information describes naturally occurring osteoarthritis of the coxofemoral joints of nonhuman primates. We report a case of naturally occurring coxofemoral joint osteoarthritis in a rhesus macaque. This case radiographically resembled hip dysplasia reported in other species and demonstrated a rapid progression in severity of lameness, with accompanying loss of muscle mass in the affected limb. We excised the femoral head and neck to alleviate the pain that accompanied the osteoarthritis. Physical therapy was initiated, and dual-energy X-ray absorptiometry and video recordings were performed to evaluate the macaque's response to surgical intervention. By 3 mo postoperatively, the macaque had regained full use of the affected limb.
