Traumatic Sciatic Nerve Lesions

Traumatic sciatic nerve mononeuropathy is a rare but severe condition sustained after acute (most frequent), chronic, or complex injuries. Trauma can be closed or open, accidental or iatrogenic. Due to its significant length, the sciatic nerve can be injured in different anatomical regions, from the sciatic notch to the knee. In addition, injuries in its peripheral divisions should be considered. Etiologies are varied and can lead to compression, stretching, or cutting of the sciatic nerve in the early period or late by scar or heterotopic ossification (mainly near the hip) enclosing the nerve.
