Evaluation of Carpal Arch Widening and Outcomes After Carpal Tunnel Release.

Purpose: The purpose of this study was to compare the carpal arch widths between baseline and 6 months after open carpal tunnel release, and to determine whether any increase in the carpal arch width was associated with clinical outcomes of surgery.

Methods: We measured carpal arch widths in standardized carpal tunnel radiographs before, and 6 months after, open carpal tunnel release in 76 patients with carpal tunnel syndrome. Clinical outcomes were assessed for grip strength change and perceived disability using the Disabilities of the Arm, Shoulder, and Hand questionnaire at 6-month follow-up.

Is Botulinum Toxin Type A a Valuable Adjunct During Femoral Lengthening? A Randomized Trial.

Background: Reduced joint ROM and distraction-induced pain are common complaints of patients who have undergone gradual femoral lengthening. Attempts to reduce the effects of lengthening on joint motion have included the use of botulinum toxin to reduce the muscle forces that restrict motion. The benefits of this approach during femoral lengthening, however, have not been conclusively established.

Biomechanical comparison of rotational activities between anterior cruciate ligament- and posterior cruciate ligament-reconstructed patients.

Purpose: The purpose of this study was to compare the early functional recovery using biomechanical properties between anterior cruciate ligament (ACL)- and posterior cruciate ligament (PCL)-reconstructed patients and to determine the biomechanical deficit of PCL-reconstructed patients compared to ACL-reconstructed patients.

Methods: A motion analysis system was used to measure and calculate kinematic and kinetic data for 10 patients who underwent PCL-reconstructed patients [experimental group (group 1)], 10 ACL-reconstructed patients (group 2), and 10 healthy subjects (group 3) during 45°, 90°, 135°, and 180° cutting and turn running tasks. Groups 1 and 2 were assessed at 3 (return to daily activity) and 6 months (return to light sports) postoperatively.

Displaced fracture of the coracoid process associated with acromioclavicular dislocation: a two-bird-one-stone solution.

We describe a surgical treatment for a displaced fracture of the coracoid process associated with acromioclavicular dislocation. This treatment involves fixing the coracoid process using a cannulated screw without acromioclavicular fixation under fluoroscopic guidance. The benefits of this treatment are that fixation with a cannulated screw simultaneously reduces both the displaced fracture of the coracoid process and the acromioclavicular joint via the intact coracoclavicular ligament, thus reducing the complications associated with transacromial pin fixation.
