S94.3
Injury of cutaneous sensory nerve at ankle and foot level
Clinical Classification Guidelines
Medical Intelligence & Overview
Injuries to the cutaneous sensory nerves at the ankle and foot are relatively common and can result from various types of trauma. These nerves are responsible for transmitting sensory information—such as touch, pain, temperature, and vibration—from the skin to the brain. An injury to these nerves can lead to numbness, tingling, or increased sensitivity in the affected area. Proper understanding of this injury type, its causes, symptoms, and potential treatments can assist in managing recovery effectively.
Causes & Symptoms
Clinical Causes: Trauma or direct injury such as cuts, lacerations, or puncture wounds to the ankle or foot Falls or sprains that cause stretching or compressing of nerves Surgical procedures in the ankle or foot area that unintentionally damage sensory nerves Repeated or prolonged pressure on the nerve due to wear and tear or ill-fitting footwear Fractures or dislocations affecting the nerve pathways
Key Symptoms: Numbness or loss of sensation in specific areas of the ankle or foot Tingling or 'pins and needles' sensation Increased sensitivity or pain upon touch Weakness or difficulty in moving parts of the foot, depending on severity Strong or burning sensations in the affected area
Diagnostic & Treatment
Diagnosis Path: To diagnose an injury of the cutaneous sensory nerve, healthcare professionals typically perform a physical examination focusing on sensory function. Nerve conduction studies and electromyography (EMG) may be used to assess nerve activity and determine the extent of injury. Imaging studies such as ultrasound or MRI can help identify structural damage or other underlying issues. A detailed history of recent trauma or surgical procedures is also important in establishing the diagnosis.
Treatment Protocols: Treatment approaches for nerve injuries at the ankle and foot include several strategies, depending on the severity of the injury. They may encompass:
