A Morphometric Analysis of Fibularis Tertius Muscle in Eastern Indian Population
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2017, Vol 6, Issue 4
Abstract
Introduction: Fibularis tertius is a unipennate muscle of extensor compartment of leg exclusively found in humans. Fibularis tertius muscle flap is used for transposition and correcting any laxity in the ankle joint by foot surgeons. Variable insertion of the muscle may play a role in causation of torsional stress as observed in certain fractures of foot. Aim: To study the incidence of fibularis tertius muscle with its dimensions and note the variations in origin and insertion of the muscle in cadaveric limbs. Materials and Methods: Hundred cadaveric lower limbs (50 right and 50 left) were dissected and analysed macroscopically to find out the incidence, dimensions and variations in origin and insertion of the fibularis tertius muscle. Results: Fibularis tertius was present in all the limbs. It was inserted to fourth or fifth metatarsals. The length and width of the muscle and its tendon were also noted. Conclusion: Distal attachment of fibularis tertius is variable making a precise knowledge of the muscle necessary for foot surgeons in performing tendoplasty or tendon transfer surgeries.
