Comparative Study
Comparison of intramedullary nailing versus plate-screw fixation of extra-articular metacarpal fractures.
To compare the clinical and radiographic outcomes of intramedullary nail (IMN) fixation of metacarpal fractures with those of plate-screw (PS) fixation. ⋯ Therapeutic III.

The objective of this study was to measure the size and shape of Lister's tubercle and the depth of the extensor pollicis longus (EPL) groove to assess the risk of injury to the EPL tendon when performing volar plating of distal radius fractures. ⋯ The individual and combined height of Lister's tubercle and the depth of the EPL groove are considerable. This fact needs to be considered when performing volar plating of distal radius fractures because of the possibility that it might be difficult to determine precisely the presence and amount of past-pointing of the distal screws.

We tested the hypothesis that preoperative expectations affect postoperative satisfaction and arm-specific, self-reported health status after elective carpal tunnel release. ⋯ Prognostic III.

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.
