Brief Summary

In recent years, hand-held retractors have been applied to assist in Wiltse approach to perform canal decompression, causing less paraspinal muscle injury and yielding better postoperative clinical outcomes than P-TLIF. However, few prospective studies have been conducted comparing the clinical and radiological outcomes between Wiltse TLIF and P-TLIF, both assisted by hand-held retractors. Therefore, further research is warranted to assess whether hand-held retractor-assisted Wiltse TLIF can yield less paraspinal muscle injury and better postoperative clinical outcomes.

Model Details: This one-year prospective controlled study compared two approaches (Wiltse TLIF vs P-TLIF) for hand-held retractors-assisted TLIF was approved by the Institutional Review Board (IRB) of our hospital. Written informed consent was obtained from all study participants. 60 eligible patients were included in this study and were divided into two groups.30patientswere included in the study group and underwent Wiltse TLIF, and 30 were included in the control group and underwent P-TLIF.
