Assessment of distal radioulnar joint instability after distal radius fracture: comparison of computed tomography and clinical examination results.
To compare computed tomography (CT) and clinical stress test findings in terms of the assessment of distal radioulnar joint (DRUJ) instability after distal radius fracture. ⋯ After distal radius fracture, CT assessments of DRUJ instability were found to be influenced by residual deformities, such as dorsal tilt, but not well correlated with stress test findings. Although CT assessments are objective, CT scans primarily show alterations of DRUJ alignment and have several risks of bias in patients with a prior distal radius fracture.

We report an unusual variant of a palmar trapezoid dislocation with a shearing fracture of the dorsal cortex treated with mini-fragment screw fixation. This patient's treatment is compared to the few previously published reports of palmarly dislocated trapezoids to assist hand surgeons facing this uncommon injury.

In most complete brachial plexus injuries, at least 1 root still is available for grafting. We report on the results obtained with reconstruction of the brachial plexus using short sural nerve grafts that connect nonavulsed roots to the anterior, posterior, or both divisions of the upper trunk. ⋯ Prognostic II.

To evaluate the subjective and objective results of surface replacement arthroplasty (SRA) for arthritis of the proximal interphalangeal (PIP) joint using the PIP-SRA implant. Emphasis is placed on causes of complications, failures, and techniques used for revision. ⋯ Therapeutic IV.

The purpose of this study was to obtain 3-dimensional and quantitative information regarding the pathological kinematics of the wrist with scaphoid nonunion using an in vivo and 3-dimensional motion analysis. We specifically tested the hypothesis that the fracture location is related to the kinematic pattern. ⋯ Carpal instability following scaphoid nonunion appears to be related to whether the fracture line passes distal or proximal to the scaphoid apex, where the dorsal scapholunate interosseous ligament and the dorsal intercarpal ligament attach. Three-dimensional imaging should be considered when assessing scaphoid nonunions to identify the exact location of the fracture. This may allow the clinician to choose the best treatment option.
