What Is Fibular Nerve Damage?
Common peroneal nerve injury is often caused by trauma, mainly manifested as sagging feet and walking with a gait; ankle joints cannot be dorsal and valgus, and toes cannot be dorsal; skin sensation on the outside of the calf and the back of the foot is reduced or missing; Atrophy of the lateral calf muscles.
Basic Information
- English name
- injury of common peroneal nerve
- Visiting department
- orthopedics
- Common locations
- Anterolateral calf, instep
- Common causes
- trauma
- Common symptoms
- Calf muscle palsy, foot dorsiflexion, eversion dysfunction, and foot drop deformity. Loss of thumb and toe function, flexion, and sensory disturbance.
Causes of common peroneal nerve injury
- Trauma causes the disease.
Clinical manifestations of common peroneal nerve injury
- The anterolateral extensor muscles of the lower leg are paralyzed, and dorsiflexion and valgus dysfunction appear. And the loss of thumb and toe function, showing a flexed state, and anterior and medial sensorial disturbances of the calf and dorsal foot.
Common peroneal nerve injury examination
- Electrophysiological examination
- The velocity of the common peroneal nerve on the affected side is slowed down, and the amplitude is reduced, and the F wave or H reflex latency is prolonged. The SEP latency is extended, the amplitude is decreased, and the wave interval is prolonged. The EMG examination of the common peroneal innervated muscle is mostly denervated potential.
- 2. Ultrasound
- It can accurately display the peripheral nerves, especially the common peroneal nerve. It can provide imaging data for clinical diagnosis and treatment and can provide a reference for surgical treatment.
Diagnosis of common peroneal nerve injury
- Diagnosis is mainly based on trauma history and clinical manifestations.
Treatment of common peroneal nerve injury
- The location of the injury is superficial and the nerves can be touched. Surgical exploration should be performed as soon as possible. If the function is not restored, tendon displacement or ankle fusion is performed at the later stage to correct the foot drop deformity. You can use a foot lifting orthosis to avoid abnormal gait caused by tiptoe sagging during walking.
