Entrapment involves pressure on the nerve where it passes through a narrow structure. Damage to the axon slows or prevents conduction of impulses through the nerve. The tibial nerve is commonly injured by fractures or other injury to the back of the knee or the lower leg. It may be damaged by pressure from lesions such as tumor , abscess , or bleeding into the knee. In some cases, no detectable cause can be identified.
Prevention is variable depending on the cause of the nerve damage.
Severe cases may cause atrophy of the foot muscles and foot deformity. They may include various blood tests, X-rays, scans, or other tests and procedures. Treatment is aimed at maximizing mobility and independent self-care. The cause should be identified and treated as appropriate. In some cases, no treatment is required and recovery is spontaneous.
