Examination of the traction effect in an artificial muscle-type dynamic traction orthosis using computed tomography.

Background: Dart-throwing motion from radial dorsiflexion to palmar flexion has recently attracted attention as a functional movement direction of the wrist joint. We developed a novel artificial muscle-type dynamic traction orthosis (DTSaM) that includes these movements. This prospective crossover controlled study aimed to compare the traction effects in the presence and absence of DTSaM using computed tomography.

Clinical outcome of the chronic flexor tenosynovitis in the hand caused by non-tuberculous mycobacterium treated by extensive tenosynovectomy and drugs.

Chronic flexor tenosynovitis in the hand caused by non-tuberculous mycobacterial (NTM) infection is uncommon. Although some authors have recommended combining surgical and drug therapy, there are few reports about the timing of drug administration after operation. The purpose of this retrospective study was to analyse the clinical outcome of the protocol, which consisted of extensive tenosynovectomy and drug therapy administered after culture results had been obtained.

Intra-articular fractures of the distal radius evaluated by computed tomography.

Purpose: To describe the fracture lines of intra-articular distal radius fractures as evaluated by computed tomography scans.

Methods: With computed tomography, we examined 95 intra-articular fractures of the distal radius from 91 patients. Multiplanar computed tomography images or 3-dimensional images, or both, were assessed.
