LUQUE, R et al. Results and complications of adjacent segment disease treated by minimally invasive lateral intersomatic arthrodesis. Acta ortop. mex [online]. 2020, vol.34, n.6, pp.388-398. Epub 13-Jun-2022. ISSN 2306-4102. https://doi.org/10.35366/99137.
Introduction:
A comparative clinical study has been conducted on patients involved using lateral intersomatic arthrodesis for the treatment of adjacent segment disease using titanium and PEEK intersomatic devices.
Material and methods:
Clinical (EVA and oswestry disability index ODI) and radiological (alignment and fusion), complications (major and minor) and quality of life (EQ5D) of 32 patients intervened from September 2015 to September 2018 have been analyzed and compared, with an average follow-up of 25 months (46-18). The average age in surgery was 66 years (39-89) and 68% of patients were women.
Results:
The most common segment involved was L3-L4 (62%) right retroperitoneal approach 86%. Lumbar EVA improved from 6.2 ± 2.12 to 4.1 ± 1.71 (p = 0.028). The LEG EVA descended from 5.3 ± 2.26 to 1.9 ± 1.58 (p = 0.02). The ODI scales improved from 50.2 ± 18.9 to 33.3 ± 10.2 (p = 0.025) and the EQ5D went from 0.52 to 0.73 (p = 0.039) with no statistically significant differences between the groups (ODI p = 0.18, EQ5D p = 0.293). Radiologically increased intervertebral height, lumbar and segmental lordosis, decreased Cobb’s angle and the overall melting rate was 84.3% (88% Ti/82% PEEK), with no differences between the groups.
Conclusion:
Lateral lumbar interbody fusion is an effective method for treating adjacent segment disease with clinical-radiological results and literature-like complications. No differences have been found between Ti and PEEK implants.
