Common Compression Neuropathies.

Compression neuropathies, also known as entrapment neuropathies, are common neurologic conditions seen in medicine. These often are due to mechanical injury, either compression or stretch of the affected nerve, and initially result in focal demyelinating changes. If left untreated, secondary axonal injury and lasting disability can result. Patients typically present with pain, sensory changes, and potentially weakness in the distribution of the affected nerve; therefore, a basic knowledge of neuromuscular anatomy is necessary to identify these conditions. Initial treatment of mild to moderate cases often is conservative. In severe cases or those refractory to conservative therapy, surgery should be considered.
