| Objective To study curative effect of mini open transforaminal lumbar interbody fusion (MA-OTIF) and minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) on elderly degenerative lumbar spine lesions and influences on spine morphology. Methods A total of 90 patients with elderly degenerative lumbar spine lesions who were admitted to our hospital from March 2016 to January 2018 were enrolled. They were divided into MA-OTIF group and MIS-TLIF group according to different treatment methods, 45 cases in each group. The operation time, intraoperative blood loss, postoperative drainage volume, hospitalization time, postoperative bed rest time, scores of visual analogue scale (VAS) before surgery, at 7 d, 1 month and 12 months after surgery, score of Oswestry disability index (ODI), and incidence of complications were compared between the two groups. The follow-up lasted for 12 months. The interbody fusion rate and scoliosis in the two groups were observed. Results Compared with MIS-TLIF group, operation time was shorter in MA-OTIF group, and number of X-ray exposure was less (P<0.05). There was no significant difference in intraoperative blood loss, postoperative drainage volume, hospitalization time, postoperative bed rest time, or incidence of complications between the two groups (P>0.05). At 7 d, 1 month and 12 months after surgery, VAS and ODI scores of the two groups were lower than those before surgery (P<0.05). However, there was no significant difference between the two groups (P>0.05). After follow-up for 12 months, there was no significant difference in rate of interbody fusion or incidence of scoliosis between the two groups (P>0.05). Conclusion The curative effect of MA-OTIF and MIS-TLIF is comparable on elderly degenerative lumbar spine lesions. However, operation time of MA-OTIF is shorter, and number of X-ray exposure is less. |
