The Extensor hallucis longus (EHL) muscle is a key muscle located in the anterior compartment of the lower leg. It is responsible for extending the big toe at both the metatarsophalangeal and interphalangeal joints. [1] [2] From the middle two quarters of the anterior surface of fibula and the adjacent interosseous membrane. [3]

The extensor hallucis longus muscle is a thin skeletal muscle, situated between the tibialis anterior and the extensor digitorum longus. It extends the big toe and dorsiflects the foot. It also assists with foot eversion and inversion. The muscle ends as a tendon of insertion.

2024年8月25日 · EHL (DPN), EDL (DPN) Hamstrings (tibial nerve), gluteus maximus (inferior gluteal nerve) Gluteus medius (superior gluteal nerve) ... Motor Exam. Muscle Grading System (ASIA) 0. Total paralysis. 1. Palpable or visible contraction. 2. Active movement, full range of motion, gravity eliminated. 3.

2023年10月30日 · Extensor hallucis longus is situated between tibialis anterior and extensor digitorum longus muscles. The muscle acts in three foot joints; talocrural, metatarsophalangeal and interphalangeal joints. The main action of extensor hallucis longus is to extend the big toe, but it has accessory actions in other joints as well.

2024年1月30日 · Physical examination of the anterior leg compartment should assess the range of motion and motor strength of the ankle and big toe. Motor weakness may indicate damage to the nerve or muscles of the anterior leg compartment. Waak ankle dorsiflexion and big toe extension are consistent with EHL neuromuscular pathology. EHL Tendon Injuries

The distance from bimalleolar line to proximal (BML_PO) and distal origin (BML_DO) of extensor hallucis longus (EHL) was calculated. Musculotendinous junction (MT) and midpoint (MD) of EHL was also marked.

2025年1月21日 · The Extensor hallucis longus (EHL) muscle is a thin skeletal muscle located in the lower leg, part of the anterior compartment of leg muscles. It plays a significant role in foot and toe movement. Its primary function is to extend the …

2024年12月30日 · As the name implies, the extensor hallucis longus muscle aids in the extension of the hallux at the 1 st metatarsophalangeal and interphalangeal joints in addition to supporting foot inversion and dorsiflexion.

2023年12月29日 · The extensor hallucis longus (EHL) is a thin muscle that lies deeply between the tibialis anterior and extensor digitorium longus at its superior attachment to the middle half of the fibula and interosseous membrane. It’s one of the …
