Technical considerations in pectoralis major transfer for treatment of the paralytic elbow.
Modification of pectoralis major transfer as originally described by Clark in 1946 have not addressed concerns such as diminished strength and excursion of the transfer, along with obligatory supination of the forearm. Postoperative scarring from the long oblique chest incision further compounds the psychological impairment that accompanies brachial plexopathy. One hundred forty-three brachial plexopathies were seen over a five-year period. Seven pectoralis major transfers were done to restore elbow flexion in patients with C5-6 and C5-6-7 cord injuries. Mean age and follow-up were 26 years and 25 months respectively. The modifications of this transfer we use improve strength and range of motion by preserving dual innervation of the muscle, by tubularization of the transfer, and by restoration of the transverse aponeurosis as a fascial pulley. By transfer of the pectoralis insertion to the acromion, further anterior shoulder stability may be obtained. Aesthetics can also be improved by use of selected midline and deltopectoral incisions, along with preservation of the remaining pectoralis major and minor.
