S94.10

Clinical Causes: Direct trauma to the foot or ankle from accidents or falls Repeated pressure or compression, such as from tight footwear or prolonged walking Surgical procedures involving the foot or ankle that accidentally damage the nerve Entrapment or compression due to swelling, tumors, or cysts Fractures, dislocations, or other injuries that impact the nerve pathway Diabetic neuropathy leading to nerve damage over time Inflammatory conditions or infections involving the foot or ankle

Key Symptoms: Numbness or reduced sensation on the sole of the foot, especially on the inner side Pain, burning, or tingling sensations in the affected area Weakness in muscles responsible for toe movement and foot stability Difficulty walking or standing due to altered sensation or muscle weakness Loss of reflexes related to the plantar nerve distribution Possible swelling or tenderness along the pathway of the nerve

Diagnosis Path: To confirm an injury of the medial plantar nerve, healthcare providers typically perform a comprehensive clinical examination, including assessment of sensation, muscle strength, and reflex testing. Diagnostic tests may include imaging studies such as MRI or ultrasound to visualize any structural damage or compression. Nerve conduction studies and electromyography (EMG) can help evaluate nerve function and pinpoint the extent of nerve injury.

Treatment Protocols: Rest and activity modification to reduce pressure on the affected nerve Pain management with medications such as NSAIDs or other prescribed agents Physical therapy to improve foot strength, flexibility, and function Use of orthotic devices or shoe modifications to relieve pressure and support the foot In cases of compression, surgical intervention may be necessary to decompress or repair the nerve Addressing underlying conditions such as diabetes or inflammatory disorders to prevent progression
