From this literature, we have made the following conclusions: (1) Complete cord lesions do not recover cord functional motor control. (2) Complete lesions recover one nerve root level of function at the fracture site. (3) Partial lesions recover partially. (4) The less the injury, the greater the recovery. (5) Brown-Sequard lesions recover more than central cord syndromes, which recover more than anterior cord syndromes. (6) Reduction of dislocated facets facilitates nerve root recovery. (7) Better documentation of specific pathology and recovery rates are necessary to determine the surgical benefits in complete lesions, incomplete lesions, and nerve root recovery.

The relationship between herniated lumbar disc and abnormalities of the transverse process of the lumbosacral junction was investigated. Two hundred consecutive patients with positive myelographic findings of herniated lumbar disc were reviewed. Sixty patients presented abnormalities of the transverse process to satisfy the criteria for lumbosacral transitional vertebra. ⋯ In types III and IV, there are no herniations at the level of the lumbosacral transitional vertebra and no increase in the incidence of herniations just proximal to the lumbosacral transitional vertebra. The Type II lumbosacral transitional vertebra presents herniated lumbar disc at the level of transition. It also presents a greater than normal incidence of herniations at the level just above the lumbosacral transitional vertebra.
