$fracture fibula$

The deep peroneal nerve innervates the musculature of the anterior compartment and is responsible for the dorsiflexion of the foot and toes. The superficial peroneal nerve also gives sensation to the dorsum of the foot. Damage to this nerve may result in deficits in those movements.

The superficial peroneal nerve innervates the musculature of the lateral compartment and is responsible for eversion and, to a much milder degree, plantarflexion of the foot. The triangular shape of the fibula is dictated by the insertion points of the muscles on the shaft. The fibular shaft is an origin for multiple muscles of the leg, including muscles of the anterior compartment (extensor digitorum longus, extensor hallucis longus, peroneus tertius), the lateral compartment (peroneus longus, peroneus brevis), the superficial posterior compartment (soleus), and the deep posterior compartment (tibialis posterior and flexor hallucis longus). Both the posterior and medial malleolus are part of the distal end of the tibia. This article focuses on the shaft of the fibula, which can be located between the neck of the fibula, the narrowed portion just distal to the fibular head, and the lateral malleolus, which in concert with the posterior and medial malleoli, form the ankle joint. There are several distinct portions of the fibula in terms of structure, including the head, neck, shaft, and the distal end termed the lateral malleolus. There is very limited mobility between this syndesmosis.

The fibula and tibia connect via an interosseous membrane, which attaches to a ridge on the medial surface of the fibula. At its most proximal part, it is at the knee just posterior to the proximal tibia, running distally on the lateral side of the leg where it becomes the lateral malleolus at the level of the ankle. Located posterolaterally to the tibia, it is much smaller and thinner. The fibula is one of the two long bones in the leg, and, in contrast to the tibia, is a non-weight bearing bone in terms of the shaft. The following article will focus on fractures of the fibula that are proximal to the ankle joint and the treatment of such fractures. One reason for this may be the treatment for the vast majority of isolated fibula shaft fractures is non-operative - this contrasts with the treatment of lateral malleolus fractures, which, although it is part of the fibula, technically, are categorized as ankle fractures and, therefore, have different treatment principles.

Explain the importance of collaboration and communication among the interprofessional team to ensure appropriate treatment of patients who present with an isolated fracture of the fibula shaft.Īlthough tibia and fibula shaft fractures are amongst the most common long bone fractures, there is little literature citing the incidence of isolated fibula shaft fractures.

Review the treatment options for an isolated fibula shaft fracture.

Outline the proper evaluation of a patient who has a fibula shaft fracture.

Describe the typical mechanism of isolated fibula fractures.

This activity reviews the evaluation and treatment of isolated fibula shaft fractures by an interprofessional team. Fortunately, the vast majority of isolated fibula fractures are treated nonoperatively. This type of test is also better able to distinguish between stress fractures and soft tissue injuries.Isolated fibula fractures are quite rare, much less common than fibula fractures with associated ligamentous involvement and/or tibia fractures. It can visualize lower grade stress injuries (stress reactions) before an X-ray shows changes. An MRI is considered the best way to diagnose stress fractures. An MRI uses radio waves and a strong magnetic field to create detailed images of your bones and soft tissues. However, many types of bone problems look alike on bone scans, so the test isn't specific for stress fractures. The radioactive substance is heavily absorbed by areas where bones are being repaired - showing up on the scan image as a bright white spot. A few hours before a bone scan, you'll receive a small dose of radioactive material through an intravenous line. It can take several weeks - and sometimes longer than a month - for evidence of stress fractures to show on X-rays. Stress fractures often can't be seen on regular X-rays taken shortly after your pain begins. Doctors can sometimes diagnose a stress fracture from a medical history and a physical exam, but imaging tests are often needed.
