The fibularis longus muscle, a key player in the lateral compartment of the leg, plays a crucial role in ankle stability and locomotion. It is the chief evertor of the foot. It maintains the lateral longitudinal arch and it also maintains the transverse arches of the foot. Anatomical variations of the fibularis longus muscle can manifest in diverse ways, including variations in muscle belly size, tendon number and course, and the presence of accessory muscle slips. The present study aims to contribute to the existing body of knowledge by investigating the anatomical variations of the peroneus longus muscle in a sample of Indian cadavers. A descriptive cross-sectional study was conducted in 28 specimens obtained from Anatomy lab, Government medical college, Nagapattinam specimens were dissected, well examined, photographed and relevant anatomical features were recorded.
We have observed variation in 1 specimen of fibularis longus tendon out of 28 specimens studied. So, the prevalence of specimens with variation in peroneus longus was observed to be 3.5%. Morphological features regarding origin, course and insertion were studied and the variations observed were documented. Origin and insertion were in normal pattern in all 28 specimens. The current study is a modest effort to emphasize the morphological features of an unusual arrangement of fibular tendons with clinical relevance. Understanding such anatomical variations is crucial for surgeons performing reconstructive procedures.
