Extensor Digitorum Longus
Extensor Digitorum Longus Definition
Extensor digitorum longus is the long muscle responsible for straightening the toes.
It is referred to as Musculus extensor digitorum longus in Latin and as Muscle long extenseur des orteils in French.
Extensor Digitorum Longus Location
It arises from the Lateral condyle of the tibia, the surrounding interosseous membrane and proximal 3/4th section of the fibula's medial surface. The muscle attaches to the top part of the lower leg large bone as well as to most of the small bone length in the lower leg. It runs down the length of the leg in order to affix to bones located in the four small toes.
Extensor Digitorum Longus Innervation
The muscle is supplied by the Deep peroneal nerve (S1 and L5). The muscular branches arising from the anterior tibial artery supplies blood to this muscle. The extensor digitorum longus tendon, from the proximal to the distal, is supplied blood by:
Extensor Digitorum Longus Function
The extensor digitorum longus muscle controls various movements, such as:
Extensor Digitorum Longus Pain
The extensor digitorum muscle can contribute to painful sensations in the back of the hand and the middle finger, and the aches radiate to the elbow up the back section of the forearm. Patients can also feel pain immediately above the palm and in the front part of the wrist. Extensor digitorum longus hand pain is common in athletes.
Extensor Digitorum Longus Injury Symptoms
The extensor digitorum longus injury symptoms, caused due to strain, include:
The muscle can be strained due to frequent stubbing of the toes, climbing the stairs too often, hard pedaling of bicycle too frequently and kicking the football very often. Gout, Clawtoe deformity and Diabetic neuropathy are some medical conditions resulting in this type of muscle strain. The issues can be treated with cold therapy, warm therapy and calf muscle brace and support.
Extensor Digitorum Longus Tendonitis
Extensor digitorum longus tendonitis is an inflammatory condition of the extensor tendons that run along the top part of the foot and help in straightening the toes. Patients experience pain along the top section of the foot after an extensor digitorum longus tendon injury.
Treatment includes cold therapy application and rest during the acute stage, and a full rehabilitation program including soft strengthening and extensor digitorum longus stretch exercises can be useful.
