Fibular nerve entrapment is also medically referred to as peroneal nerve entrapment or peroneal neuropathy. This is a nerve problem caused by the compression or compression of the fibular nerve. The fibular or peroneal nerve travels to the outside of the knee just under the head of the fibula (wrist bone) and reaches the muscles in the front of the ankle (anterior tibial muscle) and back of the foot (dorsal flexion muscles). This works the muscles and gives sensation from the knee down to the outer side and back of the foot. It is the nerve that allows walking by pressing on the heel. The head of the fibula is a palpable round protrusion on the outside of the knee, and fibular nerve compression usually occurs under this bony prominence on the outside of the knee. The most common reason is tight clothing and especially tight socks. Situations such as prolonged cross-legged sitting, the application of a tight cast or bandage can compress the fibular nerve by applying pressure. Fibular nerve compression caused by such pressures usually resolves spontaneously when the cause is removed.
Trauma: A trauma to the knee or leg may cause compression or damage to the nerve. Improper union and narrow plaster cast applications after fractures of the tibia and wrist often cause fibular nerve compression.
Diabetes: Diabetes can cause fibular nerve compression by increasing the risk of nerve damage. Tumors or cysts: Tumors or cysts in the leg or knee area can cause compression and compression of the nerve. Symptoms of fibular nerve entrapment may include: Numbness, tingling, or burning sensation on the outside of the ankle and the back of the foot from the knee down. Weakness or weakness in the leg and foot muscles. Difficulty walking or lifting feet with a limp (drop foot disease). Muscle wasting at the ankle and below the knee in advanced cases (atrophy in advanced cases).
Diagnosis of fibular nerve entrapment is usually made by the following methods: evaluation of symptoms and taking a history.
Physical examination: The doctor checks the leg and foot muscles, reflexes and mobility. Electromyography (EMG) and nerve conduction velocity (NCS) tests: These are tests to evaluate nerve function.
Imaging tests: X-ray, magnetic resonance imaging (MRI) or computed tomography (CT) scans may be ordered if necessary . Treatment Treatment of fibular nerve entrapment depends on determining the underlying cause and severity of symptoms.
Treatment options may include:
Conservative treatment: Medications, physical therapy and rehabilitation exercises, leg and foot relieving symptoms and promoting nerve healing with methods such as ankle splints or splints that provide support. Surgery: In advanced cases or when there is no response to conservative treatment, surgical intervention may be required to relieve compression of the nerve. During the surgery, the area where the nerve is compressed is opened and arrangements are made to reduce the pressure. Since the most common compression point is on the outside of the knee, the surgical incision is made here. Fibular nerve entrapment can lead to permanent nerve damage and muscle weakness if left untreated. Therefore, it is important to consult a healthcare professional when symptoms are felt. Your doctor will determine the most appropriate diagnosis and treatment options.
