Functional outcome after V-Y musculofascial lengthening of the flexor-pronator musculotendinous origin was assessed in conjunction with submuscular transposition of the ulnar nerve for cubital tunnel syndrome. We retrospectively evaluated 38 submuscular transpositions with V-Y lengthening in 35 patients. A functional score was calculated on a 100-point scale both preoperatively and at latest follow-up, and pain and numbness scores were assessed using visual analog scales. Mean length of follow-up was 4.9 years (range, 2.5-7.9 years). Mean functional score improved from 33.5 preoperatively to 62.7 at latest follow-up (P<.001), pain improved from 7.4 to 3.5 (P<.001), and numbness improved from 7.0 to 4.1 (P<.001). V-Y lengthening of the flexor-pronator origin is an effective alternative to musculofascial lengthening in combination with submuscular transposition for treatment of cubital tunnel syndrome.
