Arthroscopic reduction versus fluoroscopic reduction in the management of intra-articular distal radius fractures.

Purpose: Although arthroscopy offers an unparalleled view of intra-articular pathology, its use in the treatment of intra-articular distal radius fractures remains controversial. This study was designed to compare functional and radiologic outcomes of arthroscopically assisted (AA) versus fluoroscopically assisted (FA) reduction and external fixation of distal radius fractures.

Type Of Study: Retrospective, case-matched comparison of 2 different procedures.

The acute effect of peripheral nerve transection on digital thermoregulatory function.

Purpose: This study tests the hypothesis that major peripheral nerves serve as important routes for adrenergic neural fibers and therefore peripheral nerve injury affects cutaneous perfusion within the nerve's sensory innervation territory. The specific aim of the study was to determine whether an acute isolated peripheral nerve injury would result in alteration of blood flow to a specific digit, digital pain, and/or cold sensitivity.

Methods: The influence of peripheral nerves on their dominant area of autonomic vasomotor function was evaluated in 9 patients who had primary neurorrhaphy after a single complete median or ulnar nerve transection.
