Scapulothoracic tenodesis using hamstring tendon graft for treatment of problematic scapula winging: A new surgical technique.

ABSTRACT

Introduction: Winging of the scapula occurs due to dysfunction of its stabilising muscles, most commonly serratus anterior and/or trapezius, for example in facioscapulohumeral muscular dystrophy. Resultant loss of scapular control and abnormal kinematics can decrease shoulder function due to glenohumeral joint instability, loss of range of motion and pain. Previously described treatment for cases resistant to physiotherapy includes scapulothoracic arthrodesis which involves risk of non-union and metalwork failure, as well as reduced respiratory function due to immobilisation of a segment of the adjacent chest wall. Technique We present a novel surgical approach to the management of problematic scapular winging by using hamstring graft to achieve a scapulothoracic tenodesis. Discussion: We believe this technique provides an adequately stable scapula for improved shoulder movement and function, a sufficiently mobile chest wall for improved lung function and avoidance of complications specifically associated with arthrodesis.
