A case of musculi peronaeus tertius anatomic variation

摘要

In the routine dissections study for medical postgraduates, a rare anatomical variation between the right leg and the ankle was observed on the Asian male cadaver. The peronaeus tertius muscle in this cadaver's right leg divided into two tendons: the first tendon was attached to the base of the fifth metatarsal bone, and the second tendon was inserted into the base of the fourth metatarsal bone. The purpose of this paper is to provide detailed anatomical case reports, and to discuss the possible causes and mechanisms of the variation by reviewing relevant literature, so as to provide some reference for future anatomical and clinical related disease research.
