Abstract:
Objective To observe the clinic efficacy of open transforaminal lumbar interbody fusion (TLIF) compared with minimally invasive operation in treating lumbar spinal stenosis and instability among obese and non‐obese patients .Methods A ret‐rospective analysis was performed in these cases of mono‐segmental lumbar spinal stenosis and instability between January 2011 and January 2013 .Perioperative index ,clinical efficacy ,and imaging results were observed and compared between different groups .Re‐sults Thirty‐four obese cases and 105 non‐obese cases were divided into two groups ,including conventional posterior open TLIF and minimally invasive TLIF operation ,to compare the results .Perioperative indexes of obese patients were more than non‐obese patients undergone open TLIF operation way and there was significant difference(P<0 .01);while by minimally invasiveTLIF oper‐ation way ,comparing the results of the surgical blood loss and incision size between obese and non‐obese group ,there was signifi‐cant difference(P<0 .05) .However ,there was not significant difference in the operative time between two groups(P>0 .05) .No cases of slippage or breakage of implants were found among all these patients after 6 months of follow up .Postoperative VAS and ODI among these four groups were better than before(P<0 .01) .Undergoing open postoperative VAS in obese group and in non‐obese group ,there was significant difference(P< 0 .05);undergoing minimally invasive postoperative ODI in obese group and in non‐obese group ,there was significant difference(P< 0 .05) .But ,undergoing open postoperative ODI in obese group and in non‐obese group ,there was not significant difference(P>0 .05);undergoing minimally invasive postoperative VAS in obese group and in non‐obese group ,there was not significant difference(P>0 .05) .Conclusion Therefore ,obese may be risk factor in treating lumbar spinal stenosis and instability .
