Minimally Invasive In Situ Cubital Tunnel Decompression.

The purpose of this study is to describe a modified technique for a minimally invasive approach to in situ ulnar nerve decompression and to provide long-term follow-up. Thirty-one patients were included. DASH and MHQ scores were measured. Mean postoperative DASH score was 10. Eighty percent of patients achieved a postoperative DASH score under 10. Average postoperative MHQ scores were as follows: overall hand function 89, activities of daily living 93, work 92, pain 7, esthetics 95, and satisfaction 84. There were no postoperative neurological complications. No patient required open decompression or transposition. There were no wound complications. This technique addresses all points of possible compression, results in outcomes similar to those reported in the literature, and results in excellent cosmesis. It is a simple and safe technique that avoids the complexities of endoscopy and transposition and has proven to be successful.
