Wide excision of the distal ulna: A multicenter case study

Excision of the distal ulna to treat degenerative disease or instability has fallen into disfavor following reports of radioulnar impingement, carpal instability, and distal ulnar instability. Alternative procedures for reconstruction of the painful distal ulna have been developed to address these problems; the results have been generally favorable. When faced with distal ulnar reconstruction that has failed after multiple surgical procedures, or a distal ulnar neoplasm, the surgeon is left with few treatment options. Creation of a one-bone forearm, free fibular transfer, and allograft replacement have been attempted, with mixed outcomes. We report the results of 5 men and 7 women who underwent wide excision of the distal ulna, defined as surgical excision of 25% to 50% of the ulnar length. The diagnosis was failed distal radioulnar reconstruction or excision in 8 patients, osteomyelitis in 1, congenital pseudoarthrosis of the radius in 1, and neoplasm in 2. No soft tissue reconstruction was performed. Patients were examined at an average of 22 months after surgery for radiocarpal and radioulnar instability, functional outcome, pain relief, grip strength, and range of motion. Nine of the 12 procedures resulted in good or excellent results; 1 patient had a fair result after resection for osteosarcoma, and the procedure in 2 patients failed, requiring conversion to a one-bone forearm. Grip strength was restored to 75% of the normal side and range of motion was restored to 86% of the normal side. Wide excision of the distal ulna without soft tissue reconstruction is a simple and durable treatment of neoplasms of the distal ulna or salvage of the failed reconstruction of the distal radioulnar joint. We do not recommend its use in patients with incompetency or disruption of the interosseous membrane.

A multicenter prospective review of 640 endoscopic carpal tunnel releases using the transbursal and extrabursal chow techniques

A prospective study involving eight institutions was performed, incorporating 640 cases of carpal tunnel release using a dual portal endoscopic technique. The original transbursal technique described by Chow was used in 110 cases (17%), and the modified extrabursal technique was used in 530 cases (83%). An overall complication rate of 11% was found in the patients in whom the transbursal technique was used, compared with 2.2% in the patients in whom the extrabursal technique was used. The return-to-work status was followed in 291 cases (199 non-workers compensation cases and 92 workers compensation cases). The workers compensation patients returned to work in an average of 57 days, compared with 22 days for non-workers compensation patients. This study suggests the extrabursal dual portal endoscopic technique is associated with fewer complications than the transbursal approach, and patients covered by workers compensation return to work later than non-workers compensation patients.

Prospective review of 278 endoscopic carpal tunnel releases using the modified chow technique

The results of 278 endoscopic carpal tunnel releases using the extrabursal dual portal Chow technique were analyzed prospectively. The majority of patients were pain free by the 57th postoperative day. The perioperative complication rate was 1.7%. The late complication rate was 2.8%. Two cases were converted to open carpal tunnel release. The average time to return to full-duty work was 65 days in those patients covered by workers compensation, whereas it was 21 days in the privately insured (non-workers compensation) patients. The endoscopic release of the transverse carpal ligament is an effective technique for the treatment of carpal tunnel syndrome with a low complications rate. Return to full employment requires more time in those patients covered by workers compensation.

WRIST ARTHRODESIS WITH EXCISION OF THE PROXIMAL CARPAL BONES USING THE AO/ASIF WRIST FUSION PLATE AND LOCAL BONE GRAFT

We present our series of 17 patients who underwent wrist arthrodesis with excision of the proximal row carpal bones using the AO wrist fusion plate and local bone graft obtained from the excised proximal carpal row. All patients were evaluated using a questionnaire to assess pain, function, ability to perform an occupation and satisfaction with the procedure. The mean follow-up was 17 months, at which time all the fusions had united. Clinical outcome scores showed that 14 and 15 of the 17 patients achieved good or excellent results with regard to their current condition and clinical improvement, respectively. Four patients required secondary surgery, two for fractures and two for instability of the distal radio-ulnar joint unrelated to the wrist fusion.

Wrist Arthroscopy: Current Concepts

Wrist arthroscopy has steadily grown from a mostly diagnostic tool to a valuable adjunctive procedure in the treatment of myriad wrist disorders. The number of conditions that are amenable to arthroscopic treatment continues to grow. A detailed knowledge of the topographical and intracarpal anatomy, however, is essential to minimize complications and maximize the benefits. Although wrist arthroscopy can identify an anatomic abnormality, it cannot be used to differentiate between an asymptomatic degenerative condition versus a pathologic lesion that is the cause of wrist pain. A thorough wrist examination is still integral to any arthroscopic assessment. This article focuses on the methodology behind a normal arthroscopic wrist examination and discusses some of the more standard arthroscopic procedures along with the expected outcomes.

A BIOMECHANICAL ANALYSIS OF THE MODIFIED TSUGE SUTURE TECHNIQUE FOR REPAIR OF FLEXOR TENDON LACERATIONS

Thirty-six flexor tendons from fresh frozen cadavers were randomized to three types of repairs: a Kessler-Tajima, a 4-strand modified Tsuge, and a 6-strand modified Tsuge. All repairs were accompanied by a standard epitendinous suture. The repaired tendons were then tested to initial gap and ultimate failure in an Instron machine. The average forces to ultimate failure were 31.8 N (SD, 8.8), 48.4 N (SD, 10.7), and 64.2 N (SD, 11.0) respectively. The 6-strand modified Tsuge suture was significantly stronger than the other repairs and the 4-strand modified Tsuge was significantly stronger than the 2-strand Kessler-Tajima. The 6-strand and 4-strand modified Tsuge repairs appear strong enough to withstand the forces generated during early active range of motion flexor tendon rehabilitation protocols. Clinical trials are required to evaluate the usefulness of these repairs.

Endoscopic carpal tunnel release

Endoscopic carpal tunnel release is not a procedure to be taken lightly. Like many surgical procedures, it is a demanding exercise that requires exacting knowledge of the anatomy of the hand, attention to detail, and the ability to manipulate three-dimensional objects while observing them in two dimensions on a video screen. In the hands of well trained surgeons, ECTR provides patients with a safe, predictable solution to their carpal tunnel sydrome that will allow them a rapid return to normal activities with minimal postoperative discomfort.

Nonoperative Management of Scleroderma of the Hand With Tadalafil and Subatmospheric Pressure Wound Therapy: Case Report

Scleroderma, or systemic sclerosis (SS), is an autoimmune disease leading to ischemic fibrosis and widespread collagen deposition, invariably affecting the hands. Optimized medical management remains the mainstay of therapy for SS. Surgery can be considered in refractory or severely disabling cases. However, microvascular insufficiency and fibrosis can lead to wound complications and, ultimately, amputation. We present the case of a 61-year-old man with a known history of scleroderma who presented with pain, chronic infection, and ulcerations in the left hand. Initially, amputation seemed a reasonable intervention. After medical optimization with tadalafil, his ulcerations persisted. Instead of amputation, we applied a subatmospheric pressure wound therapy device to his hand. In 4 months, his wounds had healed, there was no evidence of infection, and no digits were amputated.

Accelerating recovery after trauma with free flaps

Free flap versatility and dependability make the final result of microvascular reconstruction highly predictable. Free tissue transplantation should be considered as a primary treatment after trauma. The early use of free tissue transfer will result in fewer operations and a shortened duration of hospitalization in the initial post-trauma period.

Anomalous Palmar Cutaneous Branch of the Median Nerve in the Distal Forearm : Case Report

Variations exist in the anatomy of the palmar cutaneous branch of the median nerve about the wrist. We report an anatomic variation in the course of the palmar cutaneous branch of the median nerve identified in a 17-year-old girl undergoing surgery for a scaphoid nonunion. Instead of coursing ulnar to the flexor carpi radialis tendon, deep to the antebrachial fascia between the tendons of the flexor carpi radialis and palmaris longus, the palmar cutaneous branch of the median nerve was noted to cross volar to the distal aspect of the flexor carpi radialis to lie on its radial aspect. Knowledge of the anatomic variant described in this report should encourage surgeons to dissect carefully as they expose the flexor carpi radialis during the exposure of the distal radius or scaphoid.
