BackgroundThe purpose of the study is to retrospectively review the clinical outcome of our study population of middle-aged RA patients who had suffered extensor-tendon rupture. We reported the outcome of autogenous palmaris tendon grafting of multiple extensor tendons at wrist level in 14 middle-aged rheumatoid patients.MethodsBetween Feb. 2000 to Feb. 2004, thirty-six ruptured wrist level extensor tendons were reconstructed in fourteen rheumatoid patients (11 women and three men) using autogenous palmaris longus tendon as a free interposition graft. In each case, the evaluation was based on both subjective and objective criteria, including the range of MCP joint flexion after surgery, the extension lag at the metacarpophalangeal joint before and after surgery, and the ability of the patient to work.Results and DiscussionThe average of follow-up was 54.1 months (range, 40 to 72 months). The average range of MCP joint flexion after reconstruction was 66°. The extension lag at the metacarpophalangeal joint significantly improved from a preoperative mean of 38° (range, 25°–60°) to a postoperative mean of 16° (range, 0°–30°). Subjectively all patients were satisfied with the clinical results, and achieved a return to their level of ability before tendon rupture. We found good functional results in our series of interposition grafting using palmaris longus to reconstruct extensor tendon defects in the rheumatoid patients.ConclusionReconstruction for multiple tendon ruptures is a salvage procedure that is often associated with extensor lag and impairment of overall function. Early aggressive treatment of extensor tendon reconstruction using autogenous palmaris longus tendon as a free interposition graft in the rheumatoid wrist is another viable option to achieve good clinical functional result.
Arthroscopy was used to help to reduce intra-articular fractures of the distal radius and treat soft tissue injuries in 33 acute cases. The fractures were treated by reduction under arthroscopic control and percutaneous fixation either with or without external fixation. The triangular fibrocartilage complex (TFCC) was torn in 18 of 33 patients (54%). All tears were peripheral and were repaired with arthroscopic procedures. Scapholunate (SL) ligament injuries prevailed in six (18%) patients; most of them exhibited instability in the SL joint. They received SL ligament debrided and transfixed with K-wires. Four (12%) of the patients suffered lunotriquetral (LT) ligament injuries; three of them also received transfixation with K-wires. Six (18%) of the patients exhibited chondral fractures. All fractures healed without measurable incongruity of joint surface and at follow-up (24 to 36 months), 11 patients displayed excellent results and 22 patients displayed good results according to the Mayo modified wrist score.
Volar plate arthroplasty using the Mitek Micro GII suture anchor is an effective treatment choice for acute or chronic PIP joint dorsal dislocation or subluxation.
Scapholunate (SL) instability is the most common cause of carpal instability. Pre-dynamic and dynamic type SL instability is difficult to diagnose and treat. This series reviews 17 soldiers with pre-dynamic or dynamic SL instability diagnosed by midcarpal arthroscopy and treated with dorsal capsulodesis and augmentation ligamentoplasty with partial dorsal radiocarpal (DRC) ligament procedure between 1997 and 2000. The sample included 14 males and three females. The dominant hand was involved in 15 patients. Moreover, the average patient age was 29.3 years (range 19-36 years). The diagnosis was based on clinical and arthroscopic criteria. Fifteen patients were followed up at our clinic regularly, with the follow-up period ranging from 12 to 39 months (mean 25.2 months). Fourteen patients had excellent or good results, and one patient had poor result based on Mayo Modified Wrist Score. Wrist motion in the flexion-extension plane loss averaged 18.4 degrees. Grip force increased significantly following treatment, with improvement totaling 15% of normal side. No complications were found in this series. Consequently, dorsal capsulodesis and ligamentoplasty with partial DRC ligament is considered a valuable therapeutic option for cases of pre-dynamic and dynamic SL instability.
