OBJECTIVES Although, in most cases, the symptoms of hemifacial spasm (HFS) disappear immediately after microvascular decompression (MVD), in some cases, they disappear more gradually. The objectives of this study were to observe the time course and the rate of the delayed resolution and to attempt to explain the phenomenon through long-term follow-up of HFS(More)
The significance of intraoperative electrophysiologic monitoring during microvascular decompression was evaluated prospectively in 261 patients with the hemifacial spasm from 1985 to 1995. The patients were divided into a monitored group and a non-monitored group. Identification of the offending vessels was facilitated by the monitoring during the surgical(More)
We report a case of chronic exertional compartment syndrome in the adductor pollicis that was confirmed by measuring elevated compartment pressure. Specific finding of magnetic resonance imaging, increased T2 signal intensity in the involved compartment, was also useful for the diagnosis. Pain was relieved by fasciotomy through a volar approach.
The placement of a headless screw within the scaphoid is important for successful fixation of fractured scaphoids. We ascertained the safe position of a screw using virtual collision experiments on a three-dimensionally reconstructed scaphoid bone and screw model, and applied measured angles to simple radiographs. We used images from computed tomograms of(More)
