Rate of infection after carpal tunnel release surgery and effect of antibiotic prophylaxis.

Brachial plexus birth palsy, although rare, may result in substantial and chronic impairment. Physiotherapy, microsurgical nerve reconstruction, secondary joint corrections, and muscle transpositions are employed to help the child maximize function in the affected upper extremity. ⋯ Recent literature has enhanced our understanding of the pathoanatomy and natural history of the injury as well as the surgical indications, expected outcomes, and complications; this literature has led to improved care of these patients. Based on the present evidence, recommendations for both microsurgery and shoulder reconstruction with tendon transfer and arthroscopic and open reductions are presented.

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.

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.

Wrist distraction is a common treatment maneuver used clinically for the reduction of distal radial fractures and midcarpal dislocations. Wrist distraction is also required during wrist arthroscopy to access the radiocarpal joint and has been used as a test for scapholunate ligament injury. However, the effect of a distraction load on the normal wrist has not been well studied. The purpose of this study was to measure the three-dimensional conformational changes of the carpal bones in the normal wrist as a result of a static distractive load. ⋯ Carpal distraction has a significant (p < .01) effect on the conformation of the carpus, especially at the radiocarpal and midcarpal joints. In the normal wrist, external traction causes twice as much distraction at the lunocapitate joint than at the radiolunate joint.
