OBJECT: In this article the authors present a retrospective analysis of 654 surgical outcomes in @entity1 with @entity3165 entrapments, @entity130 , and @entity5 during a 30-year period. METHODS: Data were gathered between 1968 and 1998 at Louisiana State University Health Sciences Center. Mechanisms of @entity130 or lesions included 460 entrapments at the elbow level (70%), 76 lacerations (12%), 52 stretches/contusions (8%), 34 @entity174 / @entity3029 (5%), 12 gunshot wounds (2%), two injection-induced @entity130 (0.3%), and 13 nerve @entity5 (2%). In cases of entrapment, direct operative recordings uniformly demonstrated a slowing of conduction at the elbow, even in cases in which preoperative noninvasive studies had been nondiagnostic. Intraoperative electrical "inching" studies also demonstrated significant conduction abnormalities that lie just proximal to and through the olecranon notch rather than distal, beneath the flexor carpi ulnaris muscle. There were only eight exceptions to this. Lesions not in continuity due to the injury required primary or secondary end-to-end sutures or graft repair. Aided by intraoperative nerve action potential recording, lesions in continuity received either external or internal neurolysis and split repair or resection followed by end-to-end suture or graft repair. Functional recoveries of Grade 3 or better were seen in 81 (92%) of 88 @entity1 who underwent neurolysis, 42 (72%) of 58 @entity1 who received suture repair, and 24 (67%) of 36 @entity1 who received graft repair. Nevertheless, fewer Grade 4 or 5 recoveries were reached than those seen in @entity1 with radial or median nerve @entity130 . @entity4847 were resected with preservation of preoperative function in five of seven @entity1 . CONCLUSIONS: Although difficult to obtain, useful functional recovery can be achieved with proper surgical management of @entity3165 entrapments and @entity130 .
