BACKGROUND<\/strong><\/p>

To compare the clinical and radiographic outcomes of static versus expandable interbody spacers following minimally invasive Lateral Lumbar Interbody Fusion (LLIF).<\/p>

METHODS<\/strong><\/p>

Sixty-four patients were included in this study: 32 who underwent LLIF with a static spacer, and 32 with an expandable spacer. Supplemental transpedicular posterior fixation was used in all cases. These patients were followed for 12 months post-operative. Clinical and radiographic outcomes were assessed using patients\u2019 self-reported forms and radiographs.<\/p>

RESULTS<\/strong><\/p>

Patient age, sex, operative time, blood loss, and length of hospital stay were similar between the static and expandable spacer groups (p>0.05). Mean visual analog scale, Oswestry Disability Index, and RAND-36 Item Health Survey scores improved significantly from preoperative to 12-month follow-up in both groups (p<0.05). Intervertebral disc and neuroforaminal heights increased significantly within each group from preoperative to 12-month follow-up (p<0.01), but were not different between groups (p>0.05). Segmental lordosis increased significantly in the expandable group (14.0\u00b0 \u00b1 7.9\u00b0 preoperatively to 16.4\u00b0 \u00b1 8.8\u00b0 at 12months) (p=0.01) but did not increase significantly in the static group (p=0.40). Spacer subsidence was reported in 32.4% of static and 9.8% of expandable interbody spacer levels (p<0.01).<\/p>

CONCLUSIONS<\/strong><\/p>

LLIF using expandable interbody spacers resulted in clinical outcomes similar to those of static spacers; however, the expandable group experienced a significantly greater increase in segmental lordosis and a significantly lower subsidence rate than the static group.<\/p><\/div>\r\n\t<\/div>\r\n\r\n\r\n\t\t\r\n\r\n<\/div>\r\n<\/div>\n\n\t<\/div>\r\n<\/section>\r\n\n","protected":false},"excerpt":{"rendered":"
