OBJECTIVEThe purpose of this study was to compare shoulder abduction and external rotation (ER) after single-nerve repair of the upper trunk alone versus dual-nerve repair of both the upper trunk and the suprascapular nerve.METHODSA retrospective chart review of a single surgeon’s experience repairing obstetrical brachial plexus injuries between June 1995 and June 2015 was performed. Eight patients underwent repair of the upper trunk alone, and 10 patients underwent repair of the upper trunk and the suprascapular nerve. Shoulder abduction and ER ranges of motion (ROMs) (in degrees) were recorded preoperatively and postoperatively. Postoperative ROM and the difference in ROM gained after surgery were compared by independent t-test analysis.RESULTSThe mean follow-up time was 161.4 weeks (range 62–514 weeks, SD 124.0 weeks). The mean patient age at the time of surgery was 31.3 weeks (range 19.9–47.0 weeks, SD 6.9 weeks). The mean postoperative shoulder abduction ROMs were 145.0° (range 85°–180°, SD 39.4°) after single-nerve repair and 134.0° (range 90°–180°, SD 30.3°) after dual-nerve repair (p = 0.51). The mean postoperative shoulder ER ROMs were 67.5° (range 10°–95°, SD 28.8°) after single-nerve repair and 72.0° (range 10°–95°, SD 31.3°) after dual-nerve repair (p = 0.76).CONCLUSIONSThe authors found no difference in shoulder abduction and ER between patients who underwent single-nerve repair of the upper trunk alone and those who underwent dual-nerve repair of both the upper trunk and the suprascapular nerve.
