A study of serum sodium level among Hong Kong runners.

Objective: Hyponatremia and the associated life-threatening complications have emerged as an important issue among marathon runners. This study was conducted to estimate the serum sodium level among local marathon runners and to identify the associated risk factors of dysnatremia.

Design: Prospective observational cohort study.

F-18 FDG PET/CT in an adult case of group B streptococcal sacroiliitis.

An adult patient presented with acute severe pelvic and low-back pain. Evaluations with CT and MRI were negative/inconclusive. F-18 FDG PET/CT localized the site of pathology in right sacroiliac-joint by demonstrating hypermetabolic activities conformal with the joint's outline, signifying infectious/inflammatory sacroiliitis.

Bone-periosteum-bone graft reconstruction for chronic ulnar instability of the metacarpophalangeal joint of the thumb--minimum 5-year follow-up evaluation.

Purpose: The present study evaluated prospectively the functional and radiological results of a consecutive series of 7 patients who had bone-periosteum-bone (BPB) grafts harvested from the iliac crest for treatment of chronic ulnar instability of the metacarpophalangeal (MCP) joint of the thumb after a minimum of 60 months.

Methods: Seven thumbs from 7 patients were entered into a prospective study for surgical treatment of chronic finger joint instability. Treatment consisted of reconstruction of the ulnar collateral ligament of the MCP joint of the thumb by a BPB graft harvested from the iliac crest.

Endoscope damaged during endoscopic carpal tunnel release--the solution method.

An unusual problem occurred during the endoscopic carpal tunnel release procedure of a patient with carpal tunnel syndrome. The endoscope was damaged because of inadequate knowledge in handling the instruments. The procedure was completed smoothly with a knee arthroscope.

Comparison of methods of skeletal fixation for severely injured digits.

Our objective is to compare the results of three different methods of osteosynthesis used in severely injured digits, namely the K-wire group, the K-wire & Wire-loop group and the Plate & Screws group. The results of 38 patients with 50 severely injured fingers managed between 1994 and 2000 were reviewed. Majority of them had serious injury caused by electric-saw and Zone III was the most common level of injury using Biemer's classification.

Distal radioulnar joint dorsal instability treated with dorsal capsular reconstruction.

Six patients with post-traumatic distal radioulnar joint dorsal instability were treated with dorsal capsular reconstruction. This new technique of reconstruction requires less extensive dissection than the previously described methods in the literature and requires no tendon graft. A total of six patients treated from 1999 to 2001 were included in this study.
