Risk Factors, Management, and Prognosis of Brachial Plexopathy Following Reverse Total Shoulder Arthroplasty.

ABSTRACT

Brachial plexus injuries can have a significant impact on patient outcomes following RTSA by slowing the overall recovery and return of function. Risk factors for brachial plexopathy include traction injury related to arm positioning and exposure during the procedure, direct nerve injury from surgical dissection, and compression injury from retractor placement. Risk of nerve injury can be minimized by limiting the time spent with the arm extended and externally rotated and avoiding excessive traction on the arm during humeral preparation and implant insertion. Prompt identification of postoperative brachial plexopathy is important to optimize the recovery of function.
