Direct repair of multiple levels lumbar spondylolysis by pedicle screw laminar hook and bone grafting: clinical, CT, and MRI-assessed study.

Introduction: A prospective analysis of 6 cases with multiple-level spondylolysis treated by direct repair with pedicle screw laminar hook is presented. The objective of the study was to evaluate the clinical outcome, plain radiographs, computed tomography (CT) scan, and magnetic resonance imaging to demonstrate the result of direct repair in the treatment of multiple-level spondylolysis.

Materials And Methods: Ten patients with multiple-level spondylolysis of lumbar spine were treated with segmental pedicle screw hook fixation and autogenous bone graft.
