Subcutaneous anterior transposition of the ulnar nerve for failed decompression of cubital tunnel syndrome.

The current literature universally suggests that submuscular anterior transposition is the standard operative treatment for recurrent cubital tunnel syndrome. Regardless of the type of initial failed procedure, including submuscular transposition, 20 patients underwent anterior subcutaneous transposition of the ulnar nerve. All patients were monitored for a minimum of 2 years after surgery. The most common sites of compression were the medial intermuscular septum and the flexor-pronator aponeurosis. Fifteen patients had a good or excellent outcome; 5 patients had a fair or poor outcome. Relief of pain and paresthesias were the most consistent favorable results. Fair and poor outcomes were significantly associated with increasing age and the number of previous surgeries. Subcutaneous anterior transposition of the ulnar nerve proved to be an effective treatment for recurrent cubital tunnel syndrome.

Persistent or recurrent carpal tunnel syndrome following prior endoscopic carpal tunnel release.

A retrospective review of patients with carpal tunnel syndrome (CTS) identified 20 patients (26 wrists) who had persistent or recurrent CTS after having undergone endoscopic carpal tunnel release (ECTR). Seven wrists never had relief of the original CTS symptoms; for the remaining 19 wrists, the average time to recurrence of CTS following ECTR was 4.8 months. All cases recurred within 12 months from the ECTR. All but 1 patient reported nocturnal pain. All patients experienced morning numbness and stiffness. All wrists had positive Phalen's test results. Once diagnosed with persistent or recurrent CTS, each of the wrists underwent open carpal tunnel release (OCTR). Twenty-two wrists were available for follow-up, with all patients reporting greater satisfaction and relief after the OCTR compared with the ECTR. It is important to recognize that CTS may persist or recur after ECTR. These patients should be treated with OCTR to provide symptomatic relief and prevent the sequelae of ongoing CTS.

The nonarticulating portion of the radial head: anatomic and clinical correlations for internal fixation.

The proximal radioulnar joint was dissected in 24 cadaveric elbows to localize the area of the radial head that did not articulate with the lesser sigmoid notch of the ulna. The nonarticulating portion of the radial head was posterolateral in the anatomic position of full supination. Gross observations of the nonarticulating portion of the radial head revealed a thinner band of yellowish cartilage relative to a wider, white, glistening cartilage of the articular portion of the radial head. The nonarticular portion of the radial head did not contain the angled peak, which is most prominent in the middle of the articular portion. The average arc of the nonarticulating radial head was 113 degrees (range, 106 degrees to 120 degrees; standard deviation, 4 degrees). This nonarticulating portion of the radial head (or safe zone for prominent fixation) consistently encompassed a 90 degrees angle localized by palpation of the radial styloid and Lister's tubercle. Using these palpable distal landmarks to localize the safe zone of the radial head, 24 different cadaveric elbows were internally fixed with a plate and screws through 3 different approaches (anterior, lateral, and posterolateral). Regardless of approach, the internal fixation allowed full forearm rotation in all the specimens. Utilization of this method and anatomic landmarks to localize the nonarticular portion of the radial head may assist the surgeon in open reduction and internal fixation of fractures of the radial head and neck.

Hepatic artery aneurysm in corticosteroid-treated, adult Kawasaki's disease.

We describe a single case of Kawasaki's disease (mucocutaneous lymph node syndrome) with the rare complication of a hepatic artery aneurysm which was surgically repaired. Unusual features include arterial aneurysmal formation in the hepatic arteries rather than in coronary arteries, the unusual morphology of the hepatic artery aneurysm, and the expansion of the aneurysm after corticosteroid therapy.

Stiffness of simulated radial neck fractures fixed with 4 different devices.

We performed a structural investigation of several fixation devices for radial head and neck fixation. Fourteen pairs of fresh-frozen human elbows were used to simulate unstable radial neck fractures fixed with each of the following plates: 2.0-mm T-plate, 2.0-mm blade plate, 2.7-mm T-plate, and 2.7-mm T-plate modified with a fixed-angle blade. The plate constructs were axially loaded in compression with a materials testing machine, and stiffness was calculated from a load-deformation curve. Through use of paired comparisons, the average stiffness of the modified 2.7-mm plate was found to be significantly greater than that of either 2.0-mm plate, whereas a trend was observed for increased stiffness of the modified 2.7-mm T-plate in comparison with the standard 2.7-mm T-plate. The results indicate that two important variables affecting construct stiffness are plate thickness and incorporation of a fixed-angle blade. Given these findings, the addition of a fixed blade to the 2.7-mm plate may improve the stability of fixation of comminuted radial neck fractures.
