BACKGROUND: Conservative methods are the traditional options in the management of lumber spondylolysis whereas surgery is indicated for symptomatic patients not responding to medical treatment and cases with a multilevel pars defect. The aim of this prospective study was to evaluate the clinical, functional, and radiologic results of using bone graft and fixation with pedicular screw-rod-laminar hook construct in treatment of lumber spondylolysis. PATIENTS AND METHODS: Between October 2017 and January 2020, 20 patients with symptomatic lumbar spondylolysis not responding to conservative treatment for more than 6 months were treated by defect reconstruction fixation using bone block autografting and pedicular screw laminar hook construct. The mean follow-up time was 12.5 ± 03.5 months. All patients were examined pre- and postoperatively and followed up clinically (pain [visual analog scale]), functionally (Oswestry Disability Index, Modified Prolo Functional Economic Scales, and Macnab criteria), and radiologically (pars defect healing). Perioperative outcomes and complications were documented. RESULTS: Clinical, radiologic, and functional outcomes were significantly improved. Bony union was evident in all patients (100%). Blood loss, operative time, and hospital stay increased in cases with a multilevel pars defect and cases with associated injuries. Two cases reported complications in this study as misplaced pedicular screw and superficial wound infection. CONCLUSIONS: Reconstruction fixation of pars defect using this construct is an effective, feasible procedure in the treatment of Lumbar spondylolysis regarding the preservation of lumbar motion and avoidance of adjacent-segment problems after fusion.
