In a sample of 124 legs from 65 cadavers, Sobel et al. (1990) found fibularis quartus in 27 legs (21.8%). In 17 out of the 27 legs (63%), it originated from the belly of fibularis brevis and inserted into the peroneal trochlea. In 1 out of the 27 legs (3.7%), the muscle originated from fibularis brevis and inserted onto the fibularis longus tendon (fibularis accessorius). In another leg (3.7%), the muscle originated from the fibularis brevis muscle and inserted onto its tendon. In one leg (3.7%), the muscle originated from fibularis longus and inserted into the fibularis longus tendon. In one leg (3.7%), the muscle originated from fibularis longus and inserted into fibularis brevis. In two legs (7.4%), the muscle presented as fibularis digiti minimi (see the entry for this muscle). In two legs (7.4%), fibularis quartus originated from fibularis longus and inserted onto the peroneal trochlea. In three legs (11.1%), the muscle originated from fibularis brevis and inserted onto the lateral retinaculum.

Two fibular muscles make up the lateral compartment of the leg: the fibularis longus more laterally and fibularis brevis more medially (Plate 5.12). As these muscles pass lateral to the ankle joint, they logically evert the foot, and although they derive evolutionarily and developmentally from an ancestral/common extensor group, as noted above, they actually flex (plan-tarflex) the foot. As its name indicates, the fibularis longus is longer than the fibularis brevis. It originates more proximally from the fibula than the fibularis brevis—and distally—it passes with the brevis deep to the superior and inferior lateral retinacula and then continues all the way through the plantar surface of the foot to insert onto metatarsal 1 and the medial cuneiform (the fibularis brevis inserts onto metatarsal 5). Therefore, apart from everting and flexing (plantarflexing) the foot, the fibularis longus also supports the plantar arches of the foot.

The addition of DN to the fibularis longus muscle within a traditional rehabilitation plan demonstrated superior self-reported outcomes in individuals with CAI (Salom-Moreno et al., 2015). In this study, subjects who received DN treatment in addition to traditional balance exercises reported significantly greater improvements 8 weeks after their last DN treatment and four weeks after their last exercise treatment over traditional exercise alone. Furthermore, DN MTrPs of the fibularis longus muscle in individuals with CAI improved ankle strength, balance, and hop testing outcomes (Rossi et al., 2017). These subjects demonstrated immediate improvement following a single treatment without additional rehabilitative care. These studies together demonstrate that DN treatment has already demonstrated the ability to have enhanced or stand-alone improvements in both clinician- and patient-oriented outcomes in individuals with CAI.

Raw surface electromyography (EMG) data synchronized to the motion data were collected using a 16-channel system and dual active surface electrodes (Motion Lab Systems, Inc., Baton Rouge, LA). Electrodes were placed on the affected side for knee OA patients and the matched side for controls. The gluteus medius, biceps femoris, vastus lateralis, fibularis longus, medial gastrocnemius, and tibialis anterior muscles were assessed. Raw data were full wave rectified and low pass filtered prior to normalization relative to maximal voluntary activation. Maximal voluntary activation was determined prior to treadmill walking using the peak EMG amplitude achieved during manual muscle testing.

Doppler ultrasonography did not reveal any thrombosis, and standard ultrasonography revealed a 14 × 4 mm mass in the muscular fascia, which was confirmed by computed tomography scan with contrast enhancement. MRI revealed a low T1 and high fat saturated T1 and T2 lesion after gadolinium enhancement that was well delimited in the fascia of the fibularis longus muscle, without invasion of the soft tissues (Figure 1).
