Restoration of elbow function in severe brachial plexus paralysis via muscle transfers.
Reconstruction of elbow function in severe or late brachial plexus injuries represents a challenge to the reconstructive microsurgeons. The current sophisticated techniques of nerve reconstruction in combination with secondary local or free functional muscle transfers, may offer satisfactory outcome. Latissimus dorsi can be transferred as a pedicled or free muscle to restore elbow function. We present our experience with elbow reanimation in late cases of brachial plexus paralysis utilising latissimus dorsi muscle transfer. From 1998 to 2006 we operated 103 patients with brachial plexus paralysis. Amongst these patients, 21 were late cases and underwent latissimus dorsi muscle transfer for elbow reanimation. Ten patients had free latissimus dorsi transfer for elbow flexion. Free latissimus dorsi muscle was neurotised either directly via three intercostals in three patients or with a nerve transfer procedure using the contralateral seventh cervical nerve root in seven patients. Care was taken to maintain the proper tension to the muscle, which must hold the elbow in static flexion of about 120 degrees at the end of the procedure. Powerful elbow flexion (M4-M4+) or extension (M4) was obtained after the first 3 months in all patients who had an ipsilateral pedicled latissimus dorsi transfer. In the group of free muscle transfers, elbow flexion was seen after 6-8 months. After the initiation of muscle contraction, eight of the patients regained elbow flexion of M3-M4+. Latissimus dorsi muscle transfer is a reliable method for elbow reanimation. Appropriate postoperative management is also an important factor to obtain better outcome.
