To evaluate specific fluoroscopic views for assessment of intra-articular screw placement during locked volar plating of the distal radius. ⋯ Multiple oblique views are required for evaluation of intra-articular screw placement during locked volar plating of the distal radius. Lower angle tilt lateral views are more specific for the ulnar screws, and higher angle views are more specific for the radial screws. We suggest first placing the ulnar screws whenever possible, using lower angle tilt lateral views (15 degrees to 23 degrees ) to evaluate for intra-articular placement. The styloid screw may be placed last and can then be evaluated on the PA and tilt PA views.

The function of the brachioradialis muscle is controversial. The objective of this study was to determine primary and secondary functions of the brachioradialis under various loading tasks as measured by EMG. ⋯ The greatest EMG activity recorded from the brachioradialis occurs during elbow flexion tasks regardless of forearm position indicating that the primary function of the brachioradialis is as a consistent elbow stabilizer during flexion tasks. During rotational tasks, more EMG activity was recorded during pronation compared with that during supination tasks indicating a secondary function of the brachioradialis as a pronator.

This study presents the preliminary experience of using an intramedullary nail for fixation of primarily extra-articular fractures and "simple" intra-articular fractures of the distal radius in 10 patients. This article will review the surgical technique, indications, and complications. ⋯ Therapeutic IV.

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.
