Free Functional Muscle Transfer Tendon Insertion Secondary Advancement Procedure to Improve Elbow Flexion

One method of restoring elbow flexion in patients with brachial plexus injuries is through the use of free functional muscle transfer. Most of our patients achieve good outcome, resulting in improved usefulness of the affected limb. However, a minority of our patients have successful reinnervation of the transferred muscle but with a suboptimal strength and range of motion (ROM) of elbow flexion. In this subset of patients, we perform a secondary procedure to improve the moment arm of the muscle on the elbow joint. This involves advancing the transferred muscle distally along the radius. The technique of the advancement procedure is described. We also report on our initial series of 5 patients who underwent this advancement procedure. In one patient, there was improvement in strength alone. In another, there was improvement of the ROM alone. The remaining 3 patients had improvement of both strength and ROM.
