The imaging anatomy study of Zhuang population using transpsoas extreme lateral interbody fusion
Objective To define the safe working zone using the extreme lateral interbody fusion(XLIF). Methods We retrospectively evaluated lumbar spine MRI. Relevant parameters were measured from axial magnetic resonance images and analyzed, including the vertebrae endplate and psoas muscle diameters, the overlap between the lumbar plexus, the endplate of the vertebral body, the psoas muscle, the retroperitoneal vessels, and the angle of the retroperitoneal vessels. Results The SWZ（safe working zone）of extreme lateral interbody fusion from L1~2 to L3~4 had no significant difference. The SWZ of L4~5 level was smaller than that at L3~4 level. The right SWZ was significant smaller than the left SWZ; the SWZ of female was smaller than that of male. Conclusions (1)The left side and right side are suitable for the Zhuang population using XLIF. (2)The puncture point of the Zhuang population using XLIF lies in zone Ⅱand zone Ⅲat L1~L2,L4~L5 level (zone Ⅲ at L2~L3,L3~L4 level).
