Patient satisfaction and disability after brachial plexus surgery.

OBJECTIVE: Little is known about patient satisfaction and disability after brachial plexus surgery. Would patients undergo the procedure again, if they knew the current result beforehand? How do they rate their result and their disability? METHODS: Of 319 plexus patients who had undergone surgery between 1995 and 2005, 199 received a 65-item questionnaire. Measurement instruments included a new plexus-specific outcome questionnaire (Ulm Questionnaire) with categories of satisfaction, functionality, pain, comorbidities, and work; and the disability of the arm, shoulder, and hand questionnaire (DASH; scale, 0-100). RESULTS: Of 99 returned questionnaires, 70 were returned in a useful form for evaluation. The results of patients with C5-C6 lesions (21 of 70) are as follows: 90% (19 of 21) would undergo surgery again, 95% (20 of 21) were satisfied with the result, and 86% (18 of 21) subjectively improved. The mean DASH score was 41 (standard deviation [SD], 24). The results of patients with C5-C7 lesions (6 of 70) are as follows: 50% (3 of 6) were satisfied and would undergo surgery again, and 67% (4 of 6) improved. The mean DASH score was 46 (SD, 13). The results of patients with C5-T1 lesions (43 of 70) are as follows: 67% (29 of 43) would undergo surgery again, 81% (35 of 42) were satisfied, and 74% (32 of 43) reported improvement. The mean DASH score was 58 (SD, 26). The overall mean DASH score was 52 (SD, 26). Pain since the injury was prevalent in 86% of patients (60 of 70), back pain in 53%, and depression/anxiety in 21%. Fifty-two percent of those who worked before their injury (27 of 53 patients) remained unemployed or incapacitated for work. Forty-five percent of previous workers (24 of 53) returned to their former occupation. Occupational retraining was successful for 70% of patients (16 of 23). The mean duration until return to work was 9 months overall and 5 months for those who returned to their previous occupation. CONCLUSION: Eighty-seven percent of patients were satisfied with the results and 83% would undergo the procedure again. Despite a high satisfaction rate, patients remained considerably disabled, and half of the previous workers did not return to work. Occupational retraining is effective.

Surgical treatment of traumatic peroneal nerve lesions.

OBJECTIVE: In this study, we compare different surgical procedures regarding the functional outcome of traumatic peroneal nerve lesions. METHODS: In a retrospective study, 48 patients with traumatic lesions (17 iatrogenic) of the peroneal nerve were evaluated. Twenty-two patients presented with lesions in continuity displaying regenerative potential by nerve action potential recording. In these cases, surgery was restricted to either external (12/) or interfascicular neurolysis (10/). Twenty-two cases had no regenerative potential (10/) or showed discontinuity (12/) and thus were reconstructed with autologous sural nerve grafts. In four cases, a reconstructive procedure was intraoperatively abandoned as a result of the large extent of the lesion. RESULTS: Thirty-six patients with an adequate follow-up period of at least 18 months were included in this study. Among those with external neurolysis, 73% (eight out of 11) showed a good functional outcome, obviating the need for a kick-up foot brace (M >or= 4). In the interfascicular neurolysis group, 71% (five out of seven) exhibited a similar outcome. In the grafted group, however, only 28% (five out of 18) obtained a functionally useful result dependent on graft length. A graft length under 6 cm led to a functionally useful outcome in 44% of patients (four out of nine) compared with 11% (one out of nine) when the graft length was greater than or equal to 6 cm. In six patients, muscle-tendon transfers were performed, resulting in strong, useful foot lift. CONCLUSION: Peroneal nerve lesions lacking regenerative signs should be explored. A functionally useful result (M >or=4) was achieved in 72% of the patients with either external or internal neurolysis and in 28% of the patients after a nerve graft procedure. Patients in whom nerve surgery failed to reconstitute useful foot lift need to be evaluated for their suitability to undergo a tendon transfer procedure.
