An analysis of lumbar intervertebral disc prolapse.
Clinical findings and operative results of 212 operated cases of disc protrusion are analyzed in this paper. The maximum age incidence is between 21 and 40 years. In our series disc prolapse was most common between the L4-L5 disc space, mostly on the left side, whereas the L5-S1 is more common in white people. Anthropologic differences may account for the discrepancy. A careful search should be made for disc protrusion by flexing the spine and also exploring the intervertebral foramen during surgery.
