Histopathological, clinical, and electrophysiological features influencing postoperative outcomes in carpal tunnel syndrome.

Data on the outcome predictors of surgical result of carpal tunnel syndrome (CTS) is sparse and often conflicting. The purpose of this prospective comparative study was to evaluate the neurophysiologic findings and histological characteristics of the flexor tenosynovium in patients with CTS, assessing possible associations between these findings and preoperative patient status or surgical outcome. We evaluated 30 consecutive patients with a diagnosis of idiopathic CTS who were referred for surgery.

Disassembly of a distal femur modular prosthesis after tumor resection.

We report and analyze the causes of a disassembly of a newly marketed distal femur modular prosthesis in a 20-year-old man with stage IIB osteosarcoma. The disassembly occurred after discharge from the hospital, after a minor trauma. Because of the unique displacement of the femoral component, sudden operative management was performed.
