Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior decompression and instrumentation without interbody fusion. The connecting rods broke at 3 years and the patient had a residual neurological deficit. We recommend early decompression with posterior instrumentation and interbody fusion for maximum recovery of neurological function and stability of the spine.
