Force on the sacrococcygeal and ischial areas during posterior pelvic tilt in seated posture.

Background: Most posture problems encountered in persons who use wheelchairs in a seated posture for extended periods are related to sacral sitting due to posterior pelvic tilt. Posterior pelvic tilt places pressure and shearing force on the sacrococcygeal area that can lead to pressure ulcers, but the relationship between pelvic tilt and force applied to the sacrococcygeal and ischial tuberosity areas has not yet been investigated.

Objective: To investigate the relationships of posterior pelvic tilt in a seated posture with vertical force and horizontal force on the sacrococcygeal and ischial tuberosity areas.

Comparison of the volar locking plate and the bridging external fixator in the treatment of distal radius fracture based on range of wrist motion assessed by functional radiography.

Background: The authors hypothesized that an external fixator (EF) could compromise ROM compared with a volar locking plate (VP) because of the longer duration of immobilization using a VP. Postoperative ROM were therefore compared between the EF and the VP, focusing on the movement of the radiocarpal (RC) and midcarpal (MC) joints evident on radiology. The clinical outcomes of the two methods were also evaluated.

Tuberculous bicipitoradial bursitis: a case report.

An 76-year-old man with an indolent soft tissue mass on the volar aspect of the left elbow was referred to our institution with a diagnosis of a soft tissue tumor. He had a history of lung tuberculosis since the age of 30. The mass was adjacent to the biceps brachi tendon.
