Abstract

Introduction: In human beings, peroneus longus (PL) adopts a great implication as it has the function of maintenance of the plantigrade position of the foot and also conserves the arches of the human foot. The distal attachment of PL has shifted from the lateral margin of the foot to its inner margin as a result of evolution; however, its insertion encroaches on the adjacent areas of the medial most cuneiform and proximal part of the first metatarsal. Therefore, some anomalous insertions in PL are commonly expected. Methods and results: While doing dissection of cadavers for first-year MBBS students, we spotted a variation at the distal attachment of PL unilaterally in the right foot of a male cadaver. In addition to its normal insertion at the first metatarsal and medial cuneiform, an additional slip was found inserted on the base of the fifth metatarsal. Clinical relevance: Numerous pathologies are linked with the PL tendon consisting of injuries, inflammation of the tendon, fractures, tenosynovitis, rupture due to accident, tear, and dislocation.
