Lumbosacral fracture-subluxation associated with bilateral fractures of the first sacral pedicles: a case report and review of the literature.

A case of an unusual lumbosacral fracture-subluxation associated with bilateral fractures of the first sacral pedicles is described. The authors are aware of only one reported case in the literature. A 58-year-old man was involved in an accident during which his trunk was severely twisted toward the left and flexed. He also demonstrated L5 and S1 radiculopathies. He was successfully treated with surgical decompression of the L5 and S1 nerve roots with bilateral foraminotomies, followed by posterolateral arthrodesis at the lumbosacral junction using a transpedicular screw system that extended fixation into the ilia.
