Abstract:
Objectives:To investigate the clinical efficacy of bilateral mini-open Wiltse approach transforami-nal lumbar interbody fusion(MO-TLIF)in the treatment of degenerative lumbar diseases in the elderly.Meth-ods:A retrospective analysis was conducted on 62 elderly patients with single-segment degenerative lumbar diseases who underwent MO-TLIF or minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)inthe First Affiliated Hospital of Naval Medical University between September 2017 and August 2020.Among them,37 were male and 25 were female,aged 68.0±5.5 years.The patients were divided into the MO-TLIF group(32 cases)and the MIS-TLIF group(30 cases).There were no statistically significant differences between the two groups in terms of gender ratio,age,body mass index(BMI),surgical segment,disease duration,or follow-up time(P＞0.05).The differences between the two groups were compared in terms of operative time,in-traoperative blood loss,intraoperative fluoroscopy,postoperative wound drainage,time to ambulation,hospital stay,complications,and fusion rate.The visual analogue scale(VAS),lumbar Japanese Orthopedic Association(JOA)scores,and Oswestry disability index(ODI)before surgery,at 3 months postoperatively,and at the final follow-up were recorded and compared.Results:The two groups of patients all successfully completed the surgery without significant surgery-related complications.There were no statistically significant differences be-tween the MO-TLIF and MIS-TLIF groups in terms of intraoperative blood loss(80.3±25.1mL vs.72.3±21.8mL),postoperative wound drainage volume(30.7±10.2mL vs.29.3±9.0mL),or hospital stay(5.4±0.9d vs.5.4±0.8d)(P＞0.05).Compared with the MIS-TLIF group,the MO-TLIF group had shorter operative time(90.8±8.8min vs.98.3±8.0min,P=0.001)and fewer number of intraoperative fluoroscopy(4.7±0.7 times vs.7.2±1.4 times,P＜0.001).Both groups showed significant improvement in low back pain VAS score,lumbar JOA score,and ODI at postoperative 3 months and final follow-up compared with preoperative values(P＜0.001),but there were no statistically significant differences between the two groups at the same time points(P＞0.05).At the fi-nal follow-up,no internal fixation-related complications such as screw or rod breakage were observed in both groups,and all the cases achieved bone fusion.Conclusions:Bilateral MO-TLIF can achieve good therapeutic outcomes in treating single-segment degenerative lumbar diseases,which can reduce intraoperative fluoroscopy frequency and shorten operative time comparing with MIS-TLIF.
