The incidence of isthmic spondylolysis is approximately 3% to 6% in the general population. Spondylolytic defects involving multiple vertebral levels, on the other hand, are extremely rare. Only a handful of reports have examined the outcomes of surgical treatment of multi-level spondylolysis. Here, we present one case of bilateral pars defects at L3, L4, and L5. The patient, a 46-year-old female, presented with lower back pain radiating into the left lower extremity. Radiographs and CT scans of the lumbar spine revealed bilateral pars defects at L3-L5. The patient underwent lumbar discectomy and interbody fusion of L4-S1 as well as direct repair of the pars defect at L3. There were no postoperative complications, and by seven months the patient had improved clinically. While previous reports describe the use of either direct repair or fusion in the treatment of spondylolysis, we are unaware of reports describing the use of both techniques at adjacent levels.
峡部裂在普通人群中的发病率约为3%至6%。另一方面，涉及多个椎体节段的峡部裂性缺损极为罕见。仅有少数报告研究了多节段峡部裂的手术治疗结果。在此，我们报告一例L3、L4和L5双侧椎弓根峡部裂的病例。患者为一名46岁女性，表现为下背部疼痛并向左下肢放射。腰椎X线片和CT扫描显示L3-L5双侧椎弓根峡部裂。患者接受了L4-S1腰椎间盘切除术和椎间融合术以及L3椎弓根峡部裂的直接修复。术后无并发症，至七个月时患者临床症状改善。虽然先前的报告描述了在峡部裂治疗中使用直接修复或融合技术，但我们未发现有报告描述在相邻节段同时使用这两种技术的情况。
