BACKGROUND CONTEXT: Although @entity21392 is found in 6% of @entity2112 @entity1 , very little was reported on management of pars defects in this group. These @entity1 with @entity158 are most eligible for direct repair of the defect rather than lumbosacral fusion in an attempt to save motion segments. PURPOSE: The aim of this work was to analyze the clinical and radiologic outcome of pars repair in a group of adolescents who presented after surgical correction of their @entity2112 . STUDY DESIGN: A prospective nonrandomized study. @entity1 SAMPLE: Ten consecutive @entity1 with @entity21392 presenting after an average of 3 months (range, 2-7 months) from correction of their @entity2112 with @entity1643 not responding to conservative therapy and interfering with everyday activities. The mean age at operation was 16 years (range, 14-19 years). OUTCOME MEASURES: Total @entity190 , operative time, and hospital stay were recorded. Clinical outcome was assessed by the @entity717 Index (ODI), visual analog scale (VAS), and @entity1635 ( @entity1635 )-22 questionnaire. Fusion of the pars interarticularis was assessed using plain, lateral, and oblique radiographs and a computed tomography (CT) scan. METHODS: The surgical technique consisted of thorough debridement of the defect, impacting the gap created with a tricortical iliac crest graft, and rigid fixation by either pedicle screws and a V-shaped rod (five @entity1 ) or a cable-screw construct (five @entity1 ). RESULTS: @entity1 were followed up for an average of 4.5 years (range, 2-7 years). Nine @entity1 had a good-to-excellent result, returned to normal everyday life, and participated in sports when desired. The mean ODI, VAS, and @entity1635 total scores were 11 (range, 0-34), 1.1 (range, 0-2), and 92 (range, 61-108), respectively. Follow-up radiographs and CT scans revealed healing of all defects in nine cases, no signs of @entity1797 in any, and no implant-related complications. CONCLUSIONS: The results of direct repair of @entity21392 in @entity2112 @entity1 were very satisfactory both clinically and radiologically. Direct repair appears to be a logical alternative to spinal fusion; lumbar spine mobility was preserved, and precocious motion segments were saved with a relatively simple operation.
