Abstract

Aim:  To observe the occurrence of any anomalous muscle known as peroneus quartus in the lateral compartment of the leg.
Materials and Methods:  Forty seven (47) formalin fixed cadavers used for the routine dissection for the first year medical undergraduate students in Anatomy Dissection Laboratory at Srinivas Institute of Medical Sciences & Research Centre (SIMS& RC) and KMC, were chosen. Lateral compartment of the leg of these cadavers were chosen and neatly dissected.
Results: Out of these cadavers studied, we incidentally noted the Peroneus quartus muscle in the lateral compartment of the leg in two cadavers. In first case, it originated from the Peroneus longus and attached to the eminence on the lateral aspect of the calcaneum just behind the peroneal trochlea and in the second case from that of the Peroneus brevis tendon and inserted into the fifth metatarsal bone antero-medial to the main tendon and muscles in all other cadavers followed normal pattern of origin and insertions.
Conclusion:   Incidence of this variant called the peroneus quartus is rare and the knowledge of such rare anatomical variations is important to Surgeons and Orthopedicians performing various procedures around the ankle joint.
Key words: Peroneus Quartus, Peroneus compartment, Leg, Ankle joint.
