What Is the Proximal Fibula?
Most fractures are often associated with fractures of the upper end of the tibia or the tibial shaft. But direct external force can fracture the fibula head or neck. The fracture line may be oblique or horizontal. Broken end shifts are rare. Local pain, swelling and tenderness, restricted movement.

Basic Information
Causes of proximal fibula fractures
- The disease is mainly caused by traumatic factors, mostly fractures caused by direct external force acting on the outside of the calf. Trauma violence includes impact and crush injuries caused by car accidents, heavy object injuries, and blow injuries.
Clinical manifestations of proximal fibula fractures
- There is a history of injury caused by direct external force on the lateral side of the calf, pain, swelling and tenderness. Although the patient can walk without crutches, it is painful under load. Tenderness contused the fracture site at the soft tissue. However, if the tibia and fibula are squeezed in the middle of the calf, or the wound is painful when the knee is flexed and fixed, the proximal fibula may be fractured. In addition, when the affected limb flexed its knees with resistance, it caused pain due to the attachment of the biceps femoris to the fibula head.
Examination of proximal fibula fracture
- X-ray examination: X-ray can show the specific location of the fracture and the extent of the injury, which is helpful for diagnosis. For some special cases, when X-ray examination is not enough to clearly determine the condition, CT examination can be used.
Diagnosis of proximal fibula fracture
- The disease has a clear history of trauma, and can usually be diagnosed based on its history and physical examination.
Treatment of proximal fibula fractures
- Because it is rarely shifted, it does not need to be restored. Some patients do not have special treatment, and they do not cause pain when walking the affected limb without weight. For patients with severe pain, long leg tubular casts can be used to fix the full knee extension for 4 weeks. The cast extends from the middle of the thighs to the toes and is well shaped on the knees. The cast was removed after 4 weeks and the patient was allowed to walk after 6 weeks.
- Fracture of the upper fibula should pay attention to the injury of the common peroneal nerve. In some patients, the common peroneal nerve is contused or crushed, while others are trapped in the epiphysis, and the latter gradually becomes paralyzed a few weeks after the injury. The affected foot should be placed in the dorsiflexion position to relax the peroneus, anterior tibialis and extensor muscles. After 2 months without recovery, the nerve should be explored and sutured or decompressed if necessary. Very few fibula head fractures The proximal segment of the biceps femoris attached is displaced upwards and backwards. The knee joint should be flexed to fix the fracture in the normal position. Those who have not been reset by X-ray examination should be sutured. Back to normal position. Postoperatively, it was fixed in the knee flexion mode with plaster.
