Anterior compartment of leg nerve10/3/2023 Additionally, stress fractures often feel better in the morning because the bone has rested all night shin splints often feel worse in the morning because the soft tissue tightens overnight. Press your fingertips along your shin, and if you can find a definite spot of sharp pain, that's more commonly a sign of a stress fracture. The pain of shin splints is usually more generalized than that of a stress fracture. However, there are clues you can look for that will signal whether or not you should get a bone scan. A bone scan is the definitive method for diagnosing a stress fracture. Pain in the lower leg could also be a stress fracture (an incomplete crack in the bone), which is a far more serious injury than shin splints. Do Running Shoes Cause or Prevent Injury?.Superficial fibular nerve: Innervates the skin of the anterolateral leg, and dorsum of the foot (except the skin between the first and second toes).ĭeep fibular nerve: Innervates the skin between the first and second toes. In addition to these nerves, the terminal branches of the common fibular nerve also have a cutaneous function: Lateral sural cutaneous nerve - innervates the skin over the upper lateral leg.Sural communicating nerve - combines with a branch of the tibial nerve to form the sural nerve, which innervates the skin over the lower posterolateral leg.There are two cutaneous branches that arise directly from the common fibular nerve as it moves over the lateral head of the gastrocnemius: If the common fibular nerve is damaged, the patient may lose the ability to dorsiflex and evert the foot and extend the digits. It also innervates some intrinsic muscles of the foot. These muscles act to dorsiflex the foot and extend the digits. Deep fibular nerve: Innervates the muscles of the anterior compartment of the leg tibialis anterior, extensor digitorum longus and extensor hallucis longus.Superficial fibular nerve: Innervates the muscles of the lateral compartment of the leg fibularis longus and brevis.In addition, its terminal branches also provide innervation to muscles: The common fibular nerve innervates the short head of the biceps femoris muscle (part of the hamstring muscles, which flex at the knee) Common fibular nerve and its terminal branches Motor Functions Here, the common fibular nerve terminates by dividing into the superficial fibular and deep fibular nerves. To enter the lateral compartment of the leg, the nerve wraps around the neck of the fibula, passing between the attachments of the fibularis longus muscle. At this point, the nerve gives rise to two cutaneous branches, which contribute to the innervation of the skin of the leg. The common fibular nerve follows the medial border of the biceps femoris, running in a lateral and inferior direction, over the lateral head of the gastrocnemius. The nerve begins at the apex of the popliteal fossa, where the sciatic nerve bifurcates into the tibial and common fibular nerves. Sensory: Innervates the skin of the lateral leg and the dorsum of the foot.Also supplies (via branches) the muscles in the lateral and anterior compartments of the leg. Motor: Innervates the short head of the biceps femoris directly.In this article, we shall look at the anatomy of the common fibular nerve - its anatomical course, functions and clinical correlations. The common fibular nerve is a peripheral nerve of the lower limb.
