RESUMO
We investigated three sheathing materials (autogenous vein, silastic, and polyglycolic acid fine mesh) using the rat model. Forty rats were divided into five groups of eight animals each. Group A animals underwent transection of the sciatic nerve but had no repair. In Group B, a standard epineural repair was performed. In Groups C, D, and E, the nerve was repaired as in Group B with the addition of autogenous vein, Silastic, and polyglycolic acid fine mesh sheaths, respectively. Nerve regeneration and function were assessed using sciatic functional index, nerve conduction studies, and light microscopy. Sheathing methods showed no statistically significant advantage to standard epineural repair without a sheath.

A case of median nerve compression at the wrist caused by a reversed palmaris longus muscle is described. Symptoms included paresthesias in the median nerve distribution and swelling on the flexor aspect of the wrist resembling tenosynovitis. The patient was a 13-year old girl, which we believe is the youngest recorded case in the literature.
