Bitendinous palmaris longus muscle.

Abstract

The palmaris longus is one of the most variable muscles and this should be considered in surgery of the wrist where good orientation is essential. This short note describes an unusual variant which was discovered by Hacettepe University medical students, during routine dissection of the upper limb. Since the palmaris longus provides a very useful graft in tendon surgery, the surgeon should be fully aware of its anatomical variation.
