“…An additional muscle and a tendon for the 2 nd toe has been reported by Tezer and Cicekcibasi [9]. Absence of the of the extensor digitorum longus muscle tendon to the fourth toe in the right leg has been reported in a Japanese cadaver [10]. However, a case of absence of EDL tendon slip to the fifth toe and PT sending tendinous slip to the fifth toe is being reported for the first time.…”

The peroneus tertius (PT) is a small muscle with a small single tendon which gets inserted to the dorsal surface of the 5 th metatarsal base. Normally, the tendon of extensor digitorum longus (EDL) muscle divides into 4 slips on the dorsum of the foot which go to the lateral 4 toes. Variations in the tendons of these muscles are very rare. We observed a case where the tendon of EDL divided into only 3 slips which were inserted into the 2 nd , 3 rd and 4 th toes through dorsal digital expansion. The PT tendon was quite thick and it divided into 2 slips. The lateral slip was getting inserted to the dorsal surface of the 5 th metatarsal base and medial slip was continuing on to the little toe to form the dorsal digital expansion. This variation was observed during routine dissection on the left lower limb of about 55 year old female cadaver. Such anomalies are important clinically to the treating surgeon, being a tendon of importance in normal function and surgeries of the foot. Functional significance and the clinical relevance of the variations are discussed.

“…Typically, the EDL reaches the phalanges from the second to the fifth toe. However, it is possible that one of the tendons may be absent (Sakuma et al 2004), in which case, the role of the toe extensor can be performed singularly by the extensor digitorum brevis. If the absence refers only to the fifth digit, the missing tendon can be replaced by the accessory muscle, the peroneus quinti digiti, which arises with the fibularis tertius from the common muscle belly (Tubbs et al 2016).…”

“…Tendinous anomalies of the anterior crural compartment muscles are becoming increasingly well known through studies of anatomical variation (Lundeen et al ., 1983; Sakuma et al ., 2004; Ikiz & Üçerler, 2005). Specifically, supernumerary tendinous slips inserting onto the hallucal proximal phalanx or metatarsophalangeal (MP) joint capsule have been demonstrated to occur in the majority (approx.…”

During routine dissection of an adult human cadaver, a suite of tendinous anomalies was discovered in the left hallucal region. Whereas the main tendon of the extensor hallucis longus muscle inserted normally, two accessory tendons were found coursing medial and lateral to the main tendon. The most lateral tendon originated from a supernumerary muscle belly and merged with the tendon of extensor hallucis brevis to form a composite tendon. The most medial tendon crossed the metatarsophalangeal joint and joined the composite tendon deep to the tendon of extensor hallucis longus. A terminal tendon, consisting of these three contributions, inserted upon the proximal hallucal phalanx. This variant likely arose due to atypical differentiation of the common extensor muscle mass during development, and is of particular significance to clinicians performing arthroscopy, tendon transfers, and other surgical procedures.
