Comparative Study
Clinical impact of United versus nonunited fractures of the proximal half of the ulnar styloid following volar plate fixation of the distal radius.
Distal radius fractures are often associated with a fracture of the ulnar styloid at its base. This study tested the null hypothesis that there is no difference in outcome between patients with union and nonunion of a fracture of the proximal half of the ulnar styloid 6 months after volar plate fixation of a fracture of the distal radius. ⋯ Therapeutic III.

To measure pressure within the carpal tunnel (intracarpal tunnel pressures) in patients with carpal tunnel syndrome and determine the effect of quantified active hand use on both the magnitude and location of peak pressures, before and after division of the transverse carpal ligament. ⋯ Therapeutic IV.

In 2005, a prospective clinical trial with a 6-month follow-up demonstrated the efficacy of carpal tunnel release in patients 65 years and older and showed that age is not a contraindication to surgery. The purpose of this study was to determine whether there was any further improvement, maintenance of results, or recurrence of carpal tunnel symptoms 5 years after surgery. ⋯ Therapeutic IV.

Nerve growth factor (NGF), via the high-affinity receptor, tyrosine kinase A, has been widely reported as a mediator of pain caused by inflammation. A clinical trial has suggested that anti-NGF antibody is effective for pain caused by osteoarthritis of the knee. However, adverse events such as headache (8.9%), upper respiratory tract infection (7.3%), and paresthesia (6.8%) were reported. We hypothesized that inhibition of the low-affinity NGF receptor, p75 neurotrophin receptor (p75NTR), is also effective for joint pain and may reduce side effects. This study examined suppression of pain behavior and expression of pain-inducing neuropeptides such as calcitonin gene-related peptide (CGRP) and p75NTR in dorsal root ganglia neurons by a p75NTR inhibitory antibody in a rat model of wrist joint inflammatory pain. ⋯ p75NTR inhibition may be a therapeutic target for inflamed joint pain treatment with reduced adverse events.

Multicenter Study Comparative Study
Rate of infection after carpal tunnel release surgery and effect of antibiotic prophylaxis.
To determine the rate of postoperative wound infection and the association with prophylactic antibiotic use in uncomplicated carpal tunnel release surgery. ⋯ Therapeutic III.
