Pedicled pectoralis major transfer for irreparable dehiscence of the deltoid in reverse total shoulder arthroplasty: surgical technique and case report

Spontaneous avulsion of the deltoid muscle in cuff tear arthropathy is extremely rare and represents a challenge for reconstruction.13,24 In such cases, primary repair combination with reverse total shoulder arthroplasty (RTSA) may be at risk failure, as prosthesis’s success relying on functionally elongated deltoid.7,8 Owing to elongation during RTSA, reconstruction under high tension prone failure. Furthermore, deficiency after implantation an RTSA severely limiting complication only few surgical salvage options.
