Abstract
Objective To investigate the differences of erector spinae injury between the minimally invasive and conventional open approach for posterior lumbar surgery.Methods Twenty four rabbits were randomly divided into control group,conventional group,minimally invasive group,8 for each group.Morphological change of the erector spinae was observed by light microscope(Hematoxylin & Fosin Staining, Masson trichrism staining,myosin ATPase staining and tetrazolium staining)and transmission electron microscope at various times : three days , one week , two weeks,one month, two months, three months , six months after surgery.Results The pathological change of conventional group showed obvious muscle fiber atrophy, necrosis and the change of microstructure in early stage;the recovery of muscle fiber atrophy was poor even in later stage; for minimally invasive group,the erector spinae presented gently inflammatory cell infiltration, fiber necrosis and adipose infiltration in whole time, showed better recovery.Conclusion The morphological change of erector spinae has close relationship with the degree of surgical trauma,the minimallv invasive surgery can reduce the injury of erector spinae.关键词
