The authors review eight cases of lumbar intervertebral disk herniation in adolescents aged less than 16 years, with a minimum follow-up treatment of 2 years during an 18-year period. All patients presented lower back and sciatic pain, antalgic scoliosis, and a positive Lasègue sign. Nerve compression signs were present in 25+ of the cases. Seventy-five percent of the cases underwent myelography and 25% underwent computerized axial tomography. Results were good in all cases.
The authors report one case of spinal osteoid osteoma localized in the thoracic spine that was imaged through M. R. I. They report the M. R. I. aspects of the tumor. Precise localization is necessary for the correct surgical approach.
Forty six patients with idiopathic scoliosis were treated according the Harrington method. The surgical treatment was done with the Harrington distraction rod, and vertebral arthrodesis with autogenous iliac bone graft. The patients wore a Risser-Cotrel body-cast for nine months but started walking two days after casting. Good clinical results were obtained in all the patients. Final curve correction was 40%. In this series of patients no pseudoarthrosis occurred.
