Trapezius Transfer to Restore Shoulder Function in Traumatic Brachial Plexus Injury: Revisited and Modified

Abstract

Background: Trapezius transfer has shown promise to restore shoulder movements and has stood through the passage of time. We here in describe a modification of trapezius transfer technique and review the current literature available. Methods: The modified trapezius transfer in which the trapezius muscle is extended with folded tensor fascia lata graft and attached as distally possible to the deltoid insertion was done in twelve patients at tertiary health care centre in India. Post-operative splinting and staged physiotherapy were given. Results: Results were described in the form of improvement in degree of shoulder abduction and Disabilities of the Arm, Shoulder and Hand (DASH) score. Six months post-surgery there were improvement in shoulder abduction and DASH score with mean 116 degrees (10–180 degree) and 38 (23–58) respectively. One patient showed poor results due to poor compliance in post-operative period. There were no major complications observed. Conclusions: The modified technique of trapezius transfer described here is a feasible option with good biomechanical outcomes. The technique is simple and can be adopted easily by emerging brachial plexus surgeon as a technique for secondary reconstruction of shoulder joint.
