Comparative Study
The overutilization of resources in patients with acute upper extremity trauma and infection.
To compare patients with acute upper extremity injuries and infections presenting initially to the emergency department with patients transferred from outside institutions, and to evaluate triage guidelines for the appropriate transfer of these patients. ⋯ Prognostic III.

Comparative Study
Radioscapholunate arthrodesis with excision of the distal scaphoid: comparison of contact characteristics to the intact wrist.
To evaluate the midcarpal contact characteristics at the lunocapitate (LC) and scaphotrapezio-trapezoidal (STT) joints in 3 wrist conditions: intact, after simulating a radioscapholunate (RSL) arthrodesis, and after an RSL arthrodesis with distal scaphoid excision (DSE). ⋯ Radioscapholunate arthrodesis results in increased midcarpal contact pressures that may explain the clinical incidence of midcarpal arthritis. Excision of the distal scaphoid further increases contact pressures in the remaining midcarpal joint and may further increase the incidence of midcarpal arthritis. These alterations in contact characteristics of the midcarpal joint should be considered when excising the distal scaphoid for improved range of motion.

Comparative Study
Effect of partial, distal epicondylectomy on reduction of ulnar nerve strain: a cadaver study.
To compare the decrease in ulnar nerve strains using a modification of medial epicondylectomy by removing the distal half of the medial epicondyle with in situ decompression and partial medial epicondylectomy. ⋯ The results of the present cadaveric study suggest that excision of the distal half of the medial epicondyle in cubital tunnel syndrome may decrease ulnar nerve strain effectively. The clinical effect of decrease in nerve strain and the indications for the procedure need to be investigated.
