Reverse total shoulder - 19% neurological deficits

Neurologic deficit after reverse total shoulder arthroplasty: correlation with distalization

These authors assessed the prevalence and outcomes of neurologic deficit after reverse total shoulder ( RTSA) and evaluated the correlation between nonanatomic rearrangement of the shoulder joint and neurologic complications after RTSA.

Patients were evaluated clinically for neurologic deficits after the surgery. Electromyography (EMG) and nerve conduction velocity (NCV) were performed 4 weeks postoperatively.

Neurologic deficit after RTSA was found in 34 shoulders (19%). 

The mean postoperative acromiohumeral distance was 34 mm patients with nerves deficits  and 29 mm patients without nerve deficits. 

Significant differences in terms of postoperative distalization of the humerus were seen between those shoulders with neuro deficits  (24.5  mm) and those without (20.5).

 The most common forms of neurologic deficit after RTSA were axillary nerve (41.2%) and radial nerve (15%) injuries. 

Thirty shoulders (88%) had neuropraxia, and 4 shoulders (12%) had axonotmesis. 

By conservative treatment, all patients with neurologic complications achieved complete recovery without any additional surgery; the mean recovery period was 7.4 months (range: 2-38 months).
