Transhamate periscaphoid axial radial fracture dislocation of the carpus.

We report a compression injury of the wrist with a unique pattern of axial radial dislocation of the carpus. Reposition was through a dorsal and palmar approach; all disrupted ligaments were sutured, and fixation of the carpal bones was performed with K-wires. The functional result was 70% of range of motion and 75% of strength with minimal symptoms.

Injury to the upper extremity caused by extravasation of contrast medium: a true emergency.

This retrospective clinical study, over a period of four years, includes 16 patients who had extravasation of iopromidum 623 mg (Ultravist 300) in the upper extremity during computed tomography (CT). Although conservative management is sufficient in most cases, seven patients were operated on. The mean time between extravasation and operation was 155 minutes.

Long-term follow-up evaluation of denervation of the wrist.

Purpose: To evaluate the indications and results of complete wrist denervation and to focus on the correlation between results and length of follow-up evaluation.

Methods: A retrospective review was performed of 71 complete denervations of the wrist joint in 70 patients with an average follow-up period of 9.6 years (range, 1-23 y) using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.

Smoke in the operating theater: an unregarded source of danger.

Monopolar electrocautery devices are being used in operating theaters worldwide and have become a "sine qua non" in modern surgery. Despite being widespread, the use of electrocautery is not harmless, because by burning the tissue with rather low temperatures as compared with usual combustion, toxic gases evolve and particles are dispersed and are inhaled by the staff in the operating theater. Samples of this smoke, which evolves particularly densely during reduction mammaplasty, were analyzed using a carbon dioxide laser photoacoustic spectrometer.
