Randomized Controlled Trial
Five- to 18-year follow-up for treatment of trapeziometacarpal osteoarthritis: a prospective comparison of excision, tendon interposition, and ligament reconstruction and tendon interposition.
To investigate whether palmaris longus interposition or flexor carpi radialis ligament reconstruction and tendon interposition improve the outcome of trapezial excision for the treatment of basal joint arthritis after a minimum follow-up of 5 years. ⋯ The outcomes of these 3 variations of trapeziectomy were similar after a minimum follow-up of 5 years. There appears to be no benefit to tendon interposition or ligament reconstruction in the longer term.

To evaluate the functional and radiographic results of a scaphoid excision and four-corner arthrodesis technique using percutaneous headless compression screws. ⋯ These results were comparable to or better than the results of previously published techniques in terms of fusion rates, alleviation of pain, grip strength, range of motion; Mayo wrist score; and Disabilities of the Arm, Shoulder, and Hand questionnaire score. The technique exploits the theoretical advantages of strong compression between carpals while avoiding a screw-head sized hole in the lunate articular cartilage and preserving the dorsal capsular ligament attachments to the triquetrum.

We present the case of a young patient with a severely comminuted, malunited, intra-articular distal radius fracture and complete disruption of the sigmoid notch. We reconstructed the malunited distal radioulnar joint by osteotomy and repositioning the displaced sigmoid notch fragments through a combined dorsal and volar approach. At the same time, we carried out a radioscapholunate arthrodesis with distal scaphoid excision. ⋯ At the 2.5-year follow-up, the patient had essentially normal function of the distal radioulnar joint (painless, with 85° of active pronation and 75° of supination). He resumed work as a bricklayer without limitations. We conclude that sigmoid notch reconstruction by osteotomy is worthwhile in the setting of malunited distal radius whether or not the radiocarpal joint is reconstructable.

The teardrop angle (TDA) is a newly characterized radiographic parameter that some authors propose as an indicator of articular incongruity of the lunate facet. The purposes of this study were to investigate intra-observer and interobserver reliability of the measurements of the TDA and to determine whether the TDA is a reliable indicator of articular step and gap formation after distal radius fracture. ⋯ The TDA, measured on the lateral radiograph of the wrist, exhibits higher intra-observer and interobserver reliability in fractured wrists compared with uninjured wrists. On the 10° tilt views, the reliability increased in the uninjured wrists. Measurement of the TDA in plain radiographs may allow direct estimation of articular incongruity as seen on sagittal computed tomography reconstruction images.

We describe a variant of triangular fibrocartilage complex (TFCC) tears in which the superficial fibers attaching to the ulnar capsule are torn, with preservation of deep fibers inserting on the fovea. We present the clinical and magnetic resonance imaging findings and the results of arthroscopic repair in patients with this injury. ⋯ Tears of the TFCC superficial fibers with the deep fibers intact present with ulnar-sided wrist pain but without distal radioulnar joint instability. The results of outside-in repair of the articular disk back to the ulnar capsule demonstrated improvement in pain and function with no measurable objective losses. Return to sport was variable and appeared worse for those who bear weight through the hands.
