ICD-10 code S84.0 refers to an injury of the tibial nerve at the lower leg level. This classification is part of the broader category of injuries to the nerves and spinal cord, specifically focusing on the tibial nerve, which is crucial for motor and sensory functions in the lower leg and foot.

Clinical Description

Anatomy and Function of the Tibial Nerve

The tibial nerve is a major peripheral nerve that branches from the sciatic nerve. It travels down the back of the leg and innervates muscles responsible for plantar flexion (pointing the toes) and toe flexion. It also provides sensory innervation to the sole of the foot. Damage to this nerve can lead to significant functional impairments.

Mechanism of Injury

Injuries to the tibial nerve can occur due to various mechanisms, including:
- Trauma: Direct trauma from fractures, dislocations, or penetrating injuries.
- Compression: Prolonged pressure from casts, tight bandages, or swelling.
- Surgical complications: Nerve damage during orthopedic procedures in the lower leg.

Symptoms

Patients with tibial nerve injuries may present with a range of symptoms, including:
- Motor deficits: Weakness in plantar flexion and toe flexion, leading to difficulty walking or standing on tiptoes.
