ABSTRACT
Introduction and objectives: Muscular variations in the lower limb are very common. They have been described by many authors when performing cadaveric dissections and when using the different imaging techniques.
Materials and Methods: Twenty lower limbs of adult cadavers, were dissected. Lower limbs deformed by trauma, malformations and scars were excluded. The compartment was examined for the presence of an accessory muscle. If this is present, the dissection was extended and the site of its origin and insertion and passage in the retromalleolar groove was noted.
Result: A peroneus quartus was present in 4(20%) of the 20 legs. Two different area of origins and insertions. Two of them arose from the peroneus brevis muscle,and the other two from the distal fibula .three of the muscles were inserted into the retrotrochlear eminence of the calcaneum, the remaining one was inserted into the base of the first metatarsal bone.
Conclusions: This study will supplement our knowledge on the possible variations of the muscles in this region, which would be useful for lower limbs surgeons.
