“…In another study, the tendon of fibularis longus muscle was dividing into two, where first inserted into the lateral side of base of first metatarsal & medial cuneiform and other into tuberosity of the fifth metatarsal bone [15]. Also, slip from the tendon of fibularis longus joining the first dorsal interosseous muscle has also been reported in the previous studies [15,13].…”

“…The insertion of the tendon designated as peroneo -peroneus longus has been mentioned, with its insertion to the fibularis longus muscle in sole [12]. Accessory tendon arising from fibularis longus muscle and joining back with its main tendon just proximal to lateral malleolus is described [13]. The insertion of fibularis longus muscle as three tendinous slips to fifth, third and first metatarsal bones with an occasional slip to intermediate cuneiform bone [11], an additional slip to the medial cuneiform in 86.6% and an additional band close to the metatarsocuneiform joint in 30% of specimens, has been described [14].…”

To observe the occurrence of any anomalous muscle known as peroneus quartus in the lateral compartment of the leg. Materials and Methods: Forty seven (47) formalin fixed cadavers used for the routine dissection for the first year medical undergraduate students in Anatomy Dissection Laboratory at Srinivas Institute of Medical Sciences & Research Centre (SIMS& RC) and KMC, were chosen. Lateral compartment of the leg of these cadavers were chosen and neatly dissected. Results: Out of these cadavers studied, we incidentally noted the Peroneus quartus muscle in the lateral compartment of the leg in two cadavers. In first case, it originated from the Peroneus longus and attached to the eminence on the lateral aspect of the calcaneum just behind the peroneal trochlea and in the second case from that of the Peroneus brevis tendon and inserted into the fifth metatarsal bone antero-medial to the main tendon and muscles in all other cadavers followed normal pattern of origin and insertions. Conclusion: Incidence of this variant called the peroneus quartus is rare and the knowledge of such rare anatomical variations is important to Surgeons and Orthopedicians performing various procedures around the ankle joint.

“…While the usual attachment is by a strong band to the base of the first metatarsal, there is usually an additional slip to the medial cuneiform. In a case report (Jayakumari et al 2006), the muscle was shown to have an accessory tendon and tripartite insertion. The accessory tendon attached to the base of the first metatarsal, and a tendinous slip inserted into the neighboring dorsal interosseous muscle.…”

Bilateral Tripartite Insertion of the Fibularis (Peroneus) Brevis Muscle: a Case Report

et al. 2019

tripartite insertion of the fibularis (peroneus) brevis muscle: A case report. Int. J. Morphol., 37(2):481-485, 2019. SUMMARY:The fibularis brevis muscle typically inserts by a single long, robust, flat tendon upon the base of the fifth metatarsal. In this case report, we demonstrate two comparatively small accessory tendons of insertion in both the right and left limbs of an elderly cadaver. In each limb, the superior and inferior accessory tendons arose from the distal end of the main tendon of insertion to attach to, respectively, the shaft and neck of the fifth metatarsal. The bilateral presence of this comparatively rare condition is a new finding. Review of the literature reveals that these accessory tendons are most probably remnants of the inserting tendons of the atavistic muscle peroneus digiti minimi. The presence of this anomaly could affect reconstruction surgeries that utilize the inserting tendon of fibularis brevis, and treatment of avulsion fractures of the base of the fifth metatarsal.

“…Currently published literature encloses vivid data about variations in fibular group of muscles [6,[13][14][15]. Sobel et al conducted foetal study and classified AFM into two types -Type A (Fibularis quartus) and Type B (Fibulocalcaneus externus) [13].…”
