ABSTRACT

Background: Flexor digitorum brevis is an intrinsic muscle of the sole of foot that lies immediately deep to central part of plantar aponeurosis. The flexor digitorum brevis divided into four tendons for lateral four toes. Each tendon is divided into two slips at base of proximal phalanx, to allow the flexor digitorum longus tendons and get inserted on both sides of the shaft of middle phalanx. It helps to reinforce arch of foot by flexing the proximal interphalangeal and metatarsophalangeal joints of the lateral four toes. Flexor digitorum brevis muscular flap is used in the reconstruction of the heel pad and it is frequently used to correct crossover toe deformity so architecture of the foot is important because it may help in the surgical procedures during correction of above deformities.

Materials and Methods: This study was conducted on 50 feet in 25 healthy cadavers to see the variation of flexor digitorum brevis tendon.

Result: We observed that fourth tendon of flexor digitorum brevis for the fifth toe was absent in 37 cadaver feet. Out of these 14 cadavers (28 feet) showed bilateral absence of the 4th tendon while unilateral tendon absence was seen in 9 feet.

Conclusion: we concluded that such variation may occur as phylogenetic change due to minimal use of 5th toe in evolved bipedal posture. The action of flexor digitorum brevis being flexion of toes can be compensated by another long flexor of the foot.

Key words: 4thTendon, 5th toe, Flexor digitorum brevis, Metatarsophalangeal joints.
