Peripheral Nerve Entrapment
Peripheral nerve root entrapment is due to the impingement of a nerve somewhere outside of the spinal cord (Dutton). Entrapment can be from mechanical or dynamic causes (Donovan). Nerve compression can result from mass-occupying lesions (Donovan). Saphenous nerve compression may have an unknown cause or be secondary to trauma or surgery of the knee (Dutton). The superficial fibular nerve becomes entrapped after trauma or surgery (Dutton).
