Study Design. Retrospective study to investigate the benefits of ACR for lumbar degenerative diseases (LDD).
Objective. Investigate the outcomes of anterior column realignment(ACR) combined with percutaneous pedicle screw fixation(PPS) and differ for transforaminal lumbar interbody fusion (TLIF) for LDD.
Methods.
From June 2018 to December 2021, 22 consecutive patients with LDD underwent ACR. At the same time while 22 patients underwent TLIF. Preoperative and intraoperative parameters of all the patients are collected. The influences of ACR on mechanical factors and indirect decompression were evaluated by radiological parameters. Function improvements are assessed by Oswestry Disability Index (ODI), Visual Analogue Score (VAS) and Japanese Orthopaedic Association (JOA) Scores during one year of follow-up.
Results.
Preoperatively, there was no significant difference of age, sex, body mass index (BMI), ODI, VAS and JOA scores in both groups . Compared with ACR group, TLIF group had increased hospital stay (6.77±3.25 days vs. 5.0±1.11 days, P<0.05), blood loss (645.45±571.95ml vs. 235.45±78.30ml, P<0.05) and postoperative drainage (391.82±364.84 ml vs. 0 ml, P<0.001). ACR could significantly improve the radiological parameters. The short-term scores of function and pain of ACR group were higher than TLIF group.
Conclusion.
Both of ACR and TLIF could effectively resolve the symptoms of LDD. Compared with TLIF, ACR had a better improvement of short-term outcomes. ACR could be performed and improved as optional treatment strategy for LDD.
