Injury of an unspecified nerve at the lower leg level is most commonly caused by direct trauma, such as blunt or penetrating force to the area, a fracture, or a crush injury. Other potential causes include entrapment due to a bandage, splint, or cast, as well as pressure from prolonged sitting or lying in an awkward position.
Injury of an unspecified nerve at the lower leg level can be diagnosed through a physical examination, which may involve testing muscle strength and sensation in the area. Imaging tests such as MRI or CT scans may also be used to identify the exact location and extent of the injury.
Differential diagnoses for injury of an unspecified nerve at the lower leg level include nerve entrapment, neuropathy, muscle strain, and neurogenic claudication.
Treatment of injury of an unspecified nerve at the lower leg level depends on the severity of the injury. In mild cases, the affected area may be immobilized with a splint or brace and non-steroidal anti-inflammatory drugs (NSAIDs) may be used for pain relief. In more severe cases, surgery may be required to repair the nerve or to remove any damaged tissue.
The prognosis for injury of an unspecified nerve at the lower leg level is generally good if the injury is treated promptly and appropriately. In most cases, the affected area will recover completely or near-completely with appropriate treatment.
