Arthroscopic Pectoralis Minor Release After Reverse Shoulder Arthroplasty

Case: A 74-year-old male patient presenting with chronic radiating shoulder pain, paresthesias, and weakness had previously undergone reverse shoulder arthroplasty and anterior cervical discectomy and fusion for an irreparable cuff tear and cervical radiculopathy, respectively. After being diagnosed with neurogenic thoracic outlet syndrome and undergoing physiotherapy, the patient's recalcitrant condition was surgically managed with arthroscopic pectoralis minor tenotomy, suprascapular nerve release, and brachial plexus neurolysis. Conclusion: This ultimately led to complete pain relief and improved function. By sharing this case, we aim to shed light on this overlooked pathology and help prevent unnecessary procedures for others suffering from similar conditions.
