Morphometric analysis of peroneus brevis muscle in adult human cadavers

Abstract

Introduction: Keeping in view the frequency of variations in morphometry of musculature of the lower limb, Peroneus Brevis, the present work has been taken up. Under the research study of Peroneus brevis muscle in adult human cadavers of Punjab, the dissection of sixty limbs was done. This muscle takes origin from distal 2/3 of the lateral surface of fibula anterior to the Peroneus Longus and anterior and posterior crural intermuscular septa and its insertion on the lateral aspect of base of fifth metatarsal. Aim: To converse surgical relevance of dissimilarities in the morphometry of this muscle. The present paper is for the curiosity for the disciples of orthopedics, radiology and sports medicine. Materials and Methods: Material consists of 60 lower limbs related to 30 embalmed adult human cadavers (20-70 years) of known sex got from Government Medical College, Amritsar. The muscle was exposed by dissection steps provided by Cunningham’s manual of practical anatomy from origin to insertion and length and width was taken. Results: Peroneus brevis muscle was detected in all the cases (60 limbs).  Mean value of muscle belly length was 18 cm and width was 1.9 cm. While the mean length of the tendon with no muscle fibers up to insertion was 11 cm, and the mean width was found to be 0.5 cm. Conclusion: The clinical significance of this muscle is that the rebuilding of superior peroneal retinaculum can be done by using a portion of Peroneus brevis. The understanding of these variations will also help the surgeons to avoid post- operative problems such as persistence of pain and improper foot movements.
