Pediatric lumbar disc surgery: 20 patients under 15 years of age

Patients in their first or second decades of life who present with back pain without sciatica or painless scoliosis have been found to have a central lumbar disc protrusion. This study was elected to determine the difference between pediatric and adult disc symptomatology, surgical findings, and the results of surgery. Review of office and Children's Hospital records from 1958 through 1995 yielded a total of 60 patients under the age of 20 years who had lumbar discectomy by the author. Twenty were under the age of 15. This group is reported herein. All but 3 have been followed for up to 20 years. RESULTS The youngest was a boy 10 years and 8 months at operation. Only 20% complained initially of sciatic pain; 60% had it by the time of surgery; 20% never had it. The offending disc was at L5-S1 in 75%. The disc protrusion was central in 75%; no disc had ruptured. The posterior spinal ligament had ossified in the protruded position in 40%. Computed tomography (CT) scans were particularly useful. Significant antecedent trauma was present in 45%. Sixty percent were males. There was a family history of disc disease in 60%. The whereabouts of 3 of the 20 patients is unknown; their operations were 20-36 years ago. Lumbar disc disease in the first 2 decades may be missed because of the absence of sciatica. Once diagnosed, conservative therapy for as long as 2 years has failed. Lumbar discectomy in children under 15 years was safe in all cases and known to be successful in 88%.
