83STUDY OF EXTENSORS ON DORSUM OF FOOT AT K. J. SOMAIYA MEDICAL COLLEGE, MUMBAIAim to study the variant extensors on the dorsum of foot. 100 lower limbs of 50 donated embalmed cadavers (45 males & 5 females) of age group ranging from 70 to 80 years were dissected in the department of Anatomy at K. J. Somaiya Medical College, Sion, Mumbai, India. The variant extensors on the dorsum of foot were observed in 2 specimens. The neurovascular pattern in the leg and foot was also observed. The photographs of the extensors on the dorsum of foot were taken for proper documentation. In 2 specimens we observed that Peroneus tertius was absent. The existence of Peroneus tertius may help in the swing phase of bipedal walking. The Peroneus tertius may be used for tendon graft surgeries. The pull of the Peroneus tertius may be responsible for causing stress on the fifth metacarpal and account for all stress fractures in any individual. The absence of the Peroneus tertius may confuse any transplant and foot surgeons performing graft operationsdrspsawant@gmail.comResearch512015Absence of Peroneus tertius,Asymptomatic,Tendon graft surgeriesSharadkumar Pralhad SawantProfessor and Head, Department of Anatomy, K.J.Somaiya Medical College, Somaiya Ayurvihar, Eastern Express Highway, Sion, Mumbai-400 022.
