Oberlin's Transfer: Long Term Outcomes.

BACKGROUND

Brachial plexus injury is very commonly associated with road traffic accidents, and frequently affects young adults, causing significant disability and impact on quality of life. The successful treatment of upper plexus injury with the Oberlin technique to restore elbow flexion with good functional results.

METHODS

We retrieved the records of all patients with upper plexus injury who underwent Oberlin transfer operation between March 2007 and July 2012. Outcomes were assessed using the Medical Research Council (MRC) power grading system for biceps muscle, Disabilities of the Arm, Shoulder and Hand score (DASH) for patient functional outcomes and the Visual Analogue Scale for daily disability (VAS where 0- no restrictions; 10- significant limitations) for overall patient satisfaction. Follow-up was performed for at least 12 months post-operatively.

RESULTS

The average follow up period was 43.6 months. Six cases gained effective elbow flexion, improving to MRC grade 5/5 and four cases improved to MRC grade 4/5 for biceps function. The average DASH score was 27.25. One patient had serious disability with no changes after Oberlin's transfer operation. No permanent impairment of ulnar nerve function was observed. Seven out of 10 patients had begun daily work, with no discomfort and no functional impact on activities of daily living.

CONCLUSIONS

We found The Oberlin transfer is a useful salvage procedure and most effective results are for young patients with short interval between injury and operation.
