The aim of the study was to evaluate clinical and radiographic outcome of patients treated with a modified Grob technique analysing the advantages related to increased mechanical stability.
30 patients that underwent "in situ" fusion for L5-S1 spondylolisthesis were evaluated. All patients presented a low-dysplastic developmental L5-S1 spondylolisthesis. Patients were divided into two groups: A, in which L5-S1 pedicle instrumentation associated with transsacral screw fixation was performed, and B, in which L5-S1 pedicle instrumentation associated with a posterolateral interbody fusion (PLIF) was performed.
Patients treated with transdiscal L5-S1 fixation observed a faster resolution of the symptoms and a more rapid return to daily activities, especially at 3-6 months' follow-up. The technique is reliable in giving an optimal mechanical stability to obtain a solid fusion.
The advantages of this technique are lower incidence of neurologic complications, speed of execution and faster return to normal life.
本研究旨在评估采用改良 Grob 技术治疗的患者的临床和影像学结果,分析增加机械稳定性带来的优势。
对 30 例接受 L5-S1 脊椎滑脱“原位”融合的患者进行评估。所有患者均存在低度发育不良性 L5-S1 脊椎滑脱。患者分为两组:A 组行 L5-S1 椎弓根器械固定联合经骶骨螺钉固定,B 组行 L5-S1 椎弓根器械固定联合后路椎间融合术(PLIF)。
行 L5-S1 经椎间盘固定的患者观察到症状更快缓解,且更快恢复日常活动,尤其是在 3-6 个月随访时。该技术在提供最佳机械稳定性以实现坚固融合方面是可靠的。
该技术的优点为神经并发症发生率较低、手术执行速度较快且更快恢复正常生活。
