Daily Life Impact of Brachial Plexus Reconstruction in Adults: 10 Years Follow-Up

Reconstructive surgery of brachial plexus injury in adults remains a challenge. Short- and midterm follow-up results have been described in terms of impairments, such as muscle strength grading. However, psychologic management has been shown to be a major contributor in long-term results. A new, specific brachial plexus injury scale, including functional and psychologic components, was described. Objectives of this study were: (1) to assess functional long-term brachial plexus reconstruction outcomes; and (2) to validate the Mancuso scale at 10 years of follow-up.

Twenty patients with at least 10 years of follow-up were included in the study. Four patients had C5-C6 palsy and 16 had a C5-T1 injury. Shoulder abduction and elbow flexion were assessed with Medical Research Council grades. Shoulder function was evaluated with a Constant score. The 36-item short-form survey (SF36) was used to assess quality of life, and the quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) was used for patient reports of disability. The Mancuso scale was assessed and correlated to the different scores used.

At the last follow-up, the Medical Research Council grade was at least grade 3 in 10 cases (50%) of shoulder abduction and in 12 cases (60%) of elbow flexion. The Constant score was 31.4 (SD, 15.1). The SF36 score was 67.5 (SD, 4.25) and the QuickDASH was 50 (SD, 15.9). We found a correlation between the symptom score (Mancuso score) and the different quality-of-life scores (QuickDASH: coefficient, 0.491; SF36: coefficient, -0.565; limitations score: coefficient, 0.445).

This study reported results from the Mancuso scale at a minimum of 10 years of follow-up of reconstructive surgery for brachial plexus injury in adults. Correlations between this composite scale and the SF36 and QuickDASH scores suggest construct validity.
