S94.2
Injury of deep peroneal nerve at ankle and foot level
Clinical Classification Guidelines
Inclusion Terms
- Injury of terminal, lateral branch of deep peroneal nerve
Medical Intelligence & Overview
An injury to the deep peroneal nerve at the ankle and foot level involves damage to a crucial nerve that supplies sensation and motor function to parts of the lower leg, foot, and toes. Specifically, this injury affects the terminal, lateral branch of the deep peroneal nerve, which plays a vital role in foot movement and sensation. Such injuries may result from trauma, such as cuts, fractures, or compressive forces, leading to various sensory and motor problems in the affected area.
Causes & Symptoms
Clinical Causes: Trauma or injury from accidents, falls, or sports activities Fractures affecting the ankle or foot bones that impinge or damage the nerve Repetitive stress or overuse leading to nerve compression Surgical procedures around the ankle or foot area that inadvertently harm the nerve Swelling, hematoma, or other soft tissue injuries compressing the nerve
Key Symptoms: Numbness or decreased sensation on the top of the foot and between the first and second toes Unexplained weakness or difficulty lifting the toes or foot (foot drop) Pain or tingling sensations along the nerve distribution Loss of motor function affecting toe movements, especially dorsiflexion Altered sensation that may interfere with foot coordination and balance
Diagnostic & Treatment
Diagnosis Path: Healthcare providers typically perform a physical examination to assess motor strength and sensory response. Diagnostic tests like nerve conduction studies and electromyography (EMG) can evaluate nerve function and locate the site of injury. Imaging techniques such as MRI or ultrasound may help identify structural causes like swelling or fractures impinging on the nerve.
Treatment Protocols: Management primarily focuses on relieving nerve compression or addressing the injury. Treatment options may include:
