Injury of the lateral plantar nerve can be caused by direct trauma, such as a sharp blow to the foot or ankle, or indirect trauma, such as a ligament or tendon strain. It can also be caused by a herniated disc in the back, diabetes, or a tumor.
Diagnosis
Diagnosis of lateral plantar nerve injury can be made through physical examination and imaging tests such as X-rays, MRI, or CT scan. The doctor may also order a nerve conduction study to confirm the diagnosis.
Differential diagnosis
Differential diagnosis for lateral plantar nerve injury includes peroneal nerve injury, tibial nerve injury, Morton’s neuroma, and plantar fasciitis.
Treatment
Treatment of lateral plantar nerve injury may include rest, ice, compression, and elevation of the affected area, as well as non-steroidal anti-inflammatory drugs. Physical therapy may also be prescribed to help strengthen the muscles in the affected area. Surgery may be necessary in severe cases.
Prognosis
The prognosis for lateral plantar nerve injury is generally good with proper treatment. Recovery time can vary depending on the severity of the injury and the type of treatment prescribed. With prompt diagnosis and treatment, most people can expect a full recovery.
