Percutaneous Direct Repair of a Pars Defect Using Intraoperative Computed Tomography Scan: A Modification of the Buck Technique
To describe a young adult with a pars defect undergoing percutaneous direct fixation using intraoperative computed tomography (CT) scan.Summary of Background Data.
Direct pars repair has been utilized since the 1960s. There are no reports in the literature describing a percutaneous technique.Methods.
Using a percutaneous technique under the guide of intraoperative CT scan, a cannulated partially threaded screw was inserted across the pars defect.Results.
Surgery was completed without complication and the patient returned to preoperative activity level 3 months post-op. Postoperative CT scan showed a well-healed L4 pars defect.Conclusion.
Percutaneous direct pars repair using intraoperative CT scan offers the advantage of minimal soft tissue dissection, thereby reducing blood loss, infection risk, and recovery time.Conclusion.
