Results of fusion and instrumentation of thoracic and lumbar vertebral fractures in children: a prospective ten-year study.
BACKGROUND
Researches on the results of surgical treatment of thoracolumbar spine fractures are infrequent. The aim of this study was to determine midterm outcomes of surgical treatment of these fractures in a prospective survey.


METHODS
A case series study on pediatric patients with the diagnosis of thoracic and/or lumbar vertebral fractures was conducted over a ten-year period. Surgically treated patients were evaluated in the follow-up period, based on back pain, independent function, neurological status, and radiographic indices.


RESULTS
There were 102 pediatric individuals, 61 boys and 41 girls, aged 3-17 years (mean 12 years of age) with thoracic and/or lumbar spinal fractures. Motor vehicle accident was the most common mechanism of injury (45.0 %). L1 was the most frequent level of fractured vertebra (24.4 %), and pelvic fracture was the most common associated orthopedic injury (21.5 %). Totally, 20 patients underwent surgery, but only fifteen (14 boys and one girl) participated in follow-up (mean 49 months; range 12-81 months). Posterior spinal fusion and instrumentation was accomplished in 12 cases. Three patients were operated by anterior approach and fusion followed by posterior fusion and instrumentation because of delay in diagnosis. There were no major perioperative complications. Two cauda equina syndromes and two incomplete spinal cord injuries improved back to normal. Five cases (33.3 %) reported occasional back pain, and all patients were functionally independent. Radiographic indices improved significantly.


CONCLUSIONS
Spinal fusion and instrumentation in pediatric patients with unstable thoracolumbar vertebral fractures with or without spinal cord injuries have favorable radiographic and functional outcomes.
