Abstract: Systematic review and case report. Our study aims to present a new technique using three components to repair the pars defect: pedicle screws, rod and polyester band. Furthermore, we perform a systematic literature review of the previously described techniques. Spondylolysis is a common condition in children and adolescents. Depending on the severity it may be treated either nonoperatively or surgically. Surgery is required if nonoperative treatment failed to give sustained pain relief. Several surgical techniques have been described. The literature review investigates the database (MEDLINE-EMBASE-Cochrane-ScienceDirect) up to May 2019 for studies presenting a surgical technique for spondylolysis.The Screw-Rod-Band (SRB) technique combines the use of pedicle screws, a rod and a polyester band to repair the spondylolysis. The horizontal rod connects the pedicle screws. The polyester band linked to the rod passes below the spinous process to apply compressive forces on the pars. Twenty-one out of 982 studies described a surgical procedure. Eight main different techniques were identified: Isthmic Screw, Wiring, Butterfly-Plate, Hook-Screw Construct, Shaped-Rod, Laminar-Screw, and two combination technique (Lag Screw and Tension Band Fixation and Cortical Screws and Spinous-Process ModularLink). Our technique showed immediate postoperative clinical improvement. No surgical or perisurgical complication occurred. The systematic literature review revealed a great number of surgical techniques for the spondylolysis, demonstrating the lack of consensus.SRB technique is an effective and simple treatment for pars fixation. The surgical procedure puts the pars under strong compression. The results are comparable with procedures present in the literature and seems capable to reduce the invasiveness and the risk of neurological injury. 2.
