Nerve injuries are not uncommon after shoulder joint replacement.

 Neurologic complications in primary anatomic and reverse total shoulder arthroplasty: A review

This article presents a comprehensive review of nerve injuries after shoulder arthroplasty. Published rates of nerve injuries range as high as 47% for reverse total shoulders in contrast to 4% with anatomic arthroplasty.

The causes of neurologic injury in shoulder arthroplasty include transection during surgical dissection, compression secondary to retractors, traction, excessive lengthening of the arm, thermal injury from cement, cervical radiculopathy aggravated by positioning at surgery or damage due to interscalene nerve blocks.

The authors review the anatomy of each nerve in relation to its risk for injury at arthroplasty.
