Background:

A major factor limiting the use of elbow arthroscopy for contracture release is concern regarding nerve injury. The purpose of this report is to document the risk of nerve injury in a large series of arthroscopic contracture releases utilizing a safety-driven strategy.

Methods:

A series of 502 arthroscopic elbow contracture releases (including 388 osteocapsular arthroplasties) performed in 464 patients by one surgeon was reviewed retrospectively. The safety-driven step-wise strategy had been carried out in a standardized sequence: (1) Get In and Establish a View, (2) Create a Space in Which to Work, (3) Bone Removal, and (4) Capsulectomy. Neurologic complications were assessed and were followed until resolution.

Results:

No patient had a permanent nerve injury. Twenty-four patients (5%) had a transient nerve injury, associated with prolonged tourniquet time, cutaneous dysesthesia attributed to open incisions, simultaneous ulnar nerve transposition, or retractor use. All nerve deficits resolved after one day to twenty-four months, with one patient lost to follow-up.

Conclusions:

Utilizing the technique described, arthroscopic contracture release and debridement of the elbow was performed with a low risk of nerve injury.
