The purpose of this study was to assess subjective and objective outcomes in treating recurrent cubital tunnel at secondary neurolysis by nerve wrapping with a tissue engineered three-dimensional biomatrix. Five patients with a mean age of 44.1 years and an average follow-up of 13.3 months were included in the study. All patients had improvement in visual analogue scales. Four patients that had preoperative intrinsic atrophy with clawing had no clawing or intrinsic atrophy at final follow-up. Postoperatively, four of the five patients had two-point discrimination of 5 mm. Grip strength on average increased 90%. Three patients had an excellent outcome, one patient had a good outcome, and one patient had a fair outcome. All five patients said they would have surgery again.

ABSTRACT: The treatment of ulnar nerve compression at the elbow remains controversial. No single technique has yet proven its superiority. We describe a technique combining the advantages of the mini-invasive approach with those of transposition. We present the results of 30 patients, of mean age 52 years, who underwent anterior subcutaneous transposition of the ulnar nerve using a mini-invasive approach with a follow-up of more than six months. The incision measures 3 cm. The results were evaluated by measuring pain intensity, quick disabilities of the arm shoulder and hand (DASH), grip strength and pinch, and McGowan score, pre- and post-operatively. All parameters were improved post-operative. The mean pain score went from 5.5 to 4, the quick DASH from 48 to 38, mean grip strength from 28 to 31 kg, and mean pinch strength from 4.7 to 6.4 kg. The McGowan score was also improved; pre-operatively, there were 16 patients at stage III, seven patients stage II, seven patients stage I, and post-operatively there was one patient stage III, three patients stage II, 16 patients stage I, and 10 patients stage 0. Analysis of our series shows that a 3 cm incision without endoscopy allows subcutanous transposition, with results at least as good as those with other techniques. The advantages of our technique are that it is easy, has a limited approach, preserves blood supply, allows placement of the nerve in a favourable environment, and decreases nerve stretching during elbow flexion.08/2012; 38(5).

ABSTRACT: Recurrent or persistent compression neuropathies of the upper extremity, including carpal and cubital tunnel syndrome, present a difficult treatment challenge to the hand or peripheral nerve surgeon. Collagen conduits have been used successfully for decades in nerve injury repair, but have not been studied in the treatment of compression neuropathy. Patients with recurrent or persistent compression neuropathies treated with a repeat decompression and collagen wrap from a 5-year period were retrieved from the Computerized Patient Record System database and 15 patient records were identified. A systematic review was performed for all articles from 1946 to 2012 on secondary carpal and cubital tunnel syndrome. The mean age of the 15 patients treated was 63.3 years and ranged from 35 to 86 years. The patients with revision carpal tunnel decompression had an 89% subjective response rate, whereas those with revision cubital tunnel decompression had an 83% resolution or improvement of symptoms. Visual analog scale decreased from a preoperative mean 2.47 to 0.47 postoperatively and the mean number of opiate medications decreased from 0.67 to 0.40. We identified 32 papers using various treatment strategies for recurrent carpal tunnel syndrome with success rates ranging from 53% to 100%. We identified 18 papers on recurrent cubital tunnel syndrome, with success rates ranging from 33% to 100%, with a weighted success of 78.1% overall but 71.7% in the submuscular transposition group. Here we report on the novel technique of using a collagen matrix wrap in recurrent compression neuropathies with good success. The collagen wrap allows nerve gliding, protection from perineural scar formation, and a favorable microenvironment. Submuscular transposition seems to be no better than other methods of decompression for recurrent cubital tunnel syndrome in contrary to traditional teaching.Annals of plastic surgery 07/2013; 72(5).
