“…The fibular muscles are characterized by morphological variations including the presence of accessory tendons or muscles such as the fibularis digiti quinti (FDQ) and fibularis quartus (Sookur et al, ; Prakash et al, ; Demir et al, ; Yammine, ; Chaney et al, ; Olewnik et al, ). The fibularis longus and brevis tendons are also very morphologically variable (Olewnik, ; Olewnik et al, ).…”

Although there is much morphological variation in the anterior compartment of the leg, there is little information about the morphological variability of the fibularis tertius muscle (FTM). The main aim of the present study was to characterize the morphology (origin and insertion) and frequency of occurrence of the FTM and to use these findings as the basis for a new classification of the fibularis tertius tendon. Classical anatomical dissection was performed on 106 lower limbs fixed in 10% formalin. The presence of the FTM and the morphology of both its origin and its insertion were described. The FTM was present in 91 limbs (85.8%). Three types of origin were observed: Type 1, the most common type, with its origin on the distal half fibula (67%); Type 2, with the origin on the distal third fibula (22%); and Type 3, with an origin from the tendon of the extensor digitorum longus (11%). In addition, six types of insertion were distinguished. The most common was Type I (45%), a single distal attachment where the tendon inserts into the shaft of the fifth metatarsal bone. The rarest was Type VI, characterized by fusion with an additional band of the fibularis brevis tendon, which gives rise to the fourth interosseus dorsalis muscle. Two morphological variants of insertion could be distinguished, fan-shaped and band-shaped. Both the origin and insertion of the FTM are very morphologically variable, with three types of origin (Types 1-3) and six types of insertion point (Types I-VI) observed. Knowledge of such variations is essential for both clinicians and anatomists.

“…However, the additional contents reported here was PDQ, PQ in the upper tunnel and unusual accessory peroneal muscle in the lower tunnel. The PDQ origin was reported to be from PB tendon after it exited out of the upper tunnel of IPR [4,6,12] or in the upper tunnel [2]. In this study, both PDQ arose from the PB tendon in the upper tunnel.…”

“…An FDQ fused with in the fibularis tertius muscle could affect posture and the function of the lateral foot. Such a connection is antagonistic to the flexor digitorum brevis muscle as an additional tendon can also lead to clinical symptoms related to compression of adjacent vessels, nerves and tendons [ 4 ].…”

“…The fibularis muscles are highly morphologically variable, with additional bands (fibularis brevis muscle and FLM), additional tendons, and additional muscles such as the fibularis digiti quinti (FDQ), fibularis tertius and fibularis quartus [ 4 , 15 , 16 ]. The present case report describes a very rare FBM inserting as three distinct bands and reveals a new variant of the course of the FBM tendon coexisting with the fibularis digiti quinti.…”

Case report of unusual insertion of the fibularis brevis muscle

et al. 2022

The fibularis brevis and fibularis longus muscles belong to the lateral compartment of the leg. The fibularis brevis is morphologically variable, especially in the number of tendons and place of insertion. Its type of insertion is correlated with the presence of a fibularis digiti quinti, which is also anatomically variable. We present a case study based on dissection of a seventy-three-year-old female cadaver with an unusual insertion of the fibularis brevis muscle. The tendon had three bands inserting into the fifth metatarsal bone. There was a coexisting fibularis digiti quinti, which was fused with the fibularis tertius muscle. Awareness of such anatomical variation could be useful during reconstructive surgery and planning rehabilitation protocols.
