Abstract
Purpose
The purpose of this paper is to evaluate the clinical and radiographic outcomes of oblique lumbar interbody fusion to perform in L4/5 degenerative lumbar spondylolisthesis (DLS) patients who diagnosed with osteopenia.
Methods
From December 2018 to 2021 March, 90 patients were diagnosed with degenerative spondylolisthesis underwent OLIF and divided into two groups with different bone mineral density. Anterolateral screw and rod instrumentation was applied in two groups. The primary outcomes were VAS, JOA and ODI. The secondary outcomes included disc height (DH), cross-sectional height of the intervertebral foramina (CSH), cross-sectional area of the dural sac (CSA), lumbar lordorsis (LL), pelvic titlt (PT), pelvic incidence (PI) and sacrum slop (SS).
Results
All patients finished at least 1 years follow-up with 20.43 ± 4.80 months in the group A and 21.19 ± 4.68 months in the group B. The clinical symptoms were evaluated by VAS, JOA and ODI and 90 patients showed good outcomes at final follow-up (P < 0.05), with significant increases in DH, CSH and CSA. In group A, DH increased from 8.45 ± 2.28 to 10.50 ± 2.48 mm, while increased from 8.63 ± 2.15 to 10.97 ± 1.63 were recorded in group B. No statistical difference was found in DH between the two groups (P > 0.05). The cage subsidence was 1.28 ± 0.92mm in group A and 1.15 ± 0.86mm in group B (P > 0.05). There was no significant difference in the adjusted parameters of spino-pelvic between two groups (P > 0.05).
Conclusion
Oblique lumbar interbody fusion with anterolateral screw and rod instrumentation is feasible to be performed in osteopenia patients who diagnosed with degenerative spondylolisthesis.
