ABSTRACT Objective: Brachial plexus injury can lead to significant functional deficit for the patient. Elbow flexion restoration is a priority in surgical treatment. Free functional muscle transfer is an option for early or late treatment failure. This study evaluated patient characteristics and elbow flexion muscle strength after gracilis functioning muscle transfer. Methods: Medical records of 95 patients operated from 2003 to 2019 were analyzed and the following variables recorded: age, gender, nerve transfer used to motorize the gracilis muscle, time between trauma and surgery, age at surgery and elbow flexion strength after a minimum of 12 months following functioning muscle transfer. Results: 87 patients were included, averaging 30 years of age (17 to 57 years). Fifty-five achieved elbow flexion muscle strength ≥ M3 (55/87, 65%), with a mean follow-up of 37 months. The nerves used for activation of the transferred gracilis were: 45 spinal accessory, 10 intercostal, 8 median n. fascicles, 22 ulnar n. fascicles and 2 phrenic nerves. Conclusion: Functional muscle transfer is a viable surgical procedure for elbow flexion in chronic traumatic brachial plexus injuries in adults. Level of Evidence II, Retrospective study.

AbstractFree functional muscle transfer (FFMT) is a salvage procedure recommended in cases of brachial plexus injury with late presentations or failures of primary nerve reconstruction. The workhorse for most authors is the gracilis, and the most common indication is the restoration of elbow flexion. For successful revascularization of the muscle, donor vessels must be in proximity of the site of the muscle fixation and allow direct coaptation to a donor nerve, ideally without the use of nerve grafts. A major problem occurs when patients have sustained concomitant vascular injuries to the subclavian and/or axillary arteries and had previous surgical dissections in the area where the most common vascular pedicles are located. The authors report the use of the rerouted facial vessels as donors in these complex cases. The surgical technique is presented, along with three cases where the procedure was used. The flaps survived in all the patients and grade > 3/5 muscle contraction was observed in the two patients who had adequate follow-up. Conclusion: the use of the facial vessels as donor vessels is an option to revascularize a FFMT in the setting of severe vascular injury to the subclavian and axillary arteries.

The purpose of this report was to evaluate the outcome of biofeedback muscle re-education after brachial plexus reconstruction. A case series was conducted based on registry data of Rehabilitation Outpatient Clinic. A total of 20 subjects underwent surgical reconstruction to restore elbow flexion in the period of 2012-2014 were included in the study. All 20 subjects received biofeedback muscle re-education until end June 2015 (data extraction). Oucome measures were time to recovery (months) after surgical reconstruction and patients’ compliance. Recovery is considered when muscle contraction of biceps (nerve transfer) and gracilis (free functional muscle transfer/ FFMT) are ≥ 100μV, recorded using EMG-surface electrode. Of 4 subjects underwent nerve transfer, all showed recovery with median time of 9 months. Of 16 subjects underwent FFMT, 5 showed recovery with median time of 9 months. The majority of subjects in both groups could comply with once in 2 weeks rehabilitation program.

Free functional muscle transfer for brachial plexus injury is one of the alternatives to repair the upper extremity function, where usually one type of muscle is used, the gracillis. The method of using two donor muscles to restore the motor function is worth considering for a better improvement of the quality. A 36 years old man with a complete left brachial plexus injury from C5-T1 due to motorcycle accident. A double free functional muscle transfer was performed using the gracillis muscle and the adductor longus muscle with the arterial source from the thoraco-acromial artery with the phrenic and accessory nerves. The gracillis muscle is used to flex the fingers while the adductor is used for flexing the elbow. A one year post-operative evaluation showed the patient was already capable of flexing his elbow with the muscle score of 3 and also the fingers with the muscle score of 1. The double free functional muscle transfer procedure is effective in achieving the moving function of both the elbow and the hand.
