PURPOSE: To evaluate the clinical results of revision neurolysis and wrapping with porcine extracellular matrix (AxoGuard Nerve Protector, AxoGen Inc., Alachua, FL) for cubital tunnel syndrome after one previous surgical decompression.
METHODS: Twelve patients with recurrent cubital tunnel syndrome were treated with decompression, porcine extracellular matrix nerve wrap, and minimal medial epicondylectomy (if not previously performed). The average follow-up period was 41 months (range, 24-61 mo). All patients had recurrent symptoms after having previously undergone one surgical decompression. The mean patient age was 45 years (range, 30-58 y). All patients were evaluated subjectively and objectively (pain, satisfaction, static 2-point discrimination, grip strength, and pinch strength).
RESULTS: A significant improvement was demonstrated in postoperative pain levels (from 8.5 to 1.7), grip strength (from 41% to 86% of the unaffected side), and pinch strength (from 64% to 83% of the unaffected side). Static 2-point discrimination improved from an average 10.4 mm preoperatively to 7.6 mm postoperatively. Eleven of 12 patients demonstrated 2 mm or more improvement in 2-point discrimination postoperatively. There were no complications related to the use of the porcine extracellular matrix for nerve wrapping.
CONCLUSIONS: This study found that secondary decompression combined with porcine extracellular matrix nerve wrapping was an effective and safe treatment for patients with recurrent cubital tunnel syndrome.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
