Abstract

Avulsion of cervical nerve roots by traction injury to the shoulder girdle is well known, but, on the other hand, traumatic avulsion of lumbosacral nerve roots is exceedingly rare. The rarity of avulsion of lumbosacral nerve roots reflects the natural laxity of the roots and the strength and stability of the bony pelvis which offers support and protection to the nerve roots against stretching and rupture during trauma. We experienced a case of avulsion injury of L-S nerve roots associated with femoral shaft fracture. The myelography and C-T findings demonstrated multiple pseudomenigocele of dural sac at the level of the right L2, 3, 4, 5 and Sl S2 nerve roots.
