compartment leg muscle that inserts onto the lateral side of the foot. This muscle has been named fibulocalcaneus anterior. Routine dissection of the leg and foot revealed a fourth example. The muscle originated within the anterior crural compartment and inserted onto the lateral calcaneus and talus. An attachment to the talus is not included in the previous descriptions. A consideration of cruro-pedal muscle function suggests that this muscle may be an example of an evolutionary experimentation with foot evertor capabilities. Enhanced knowledge of these types of variants may increase clinical and biomechanical appreciation of the leg to foot functional relationships.
