简要总结
Lumbar interbody fusion (LIF) is atreatment strategy for various spinal disorders, including unstabledegenerative conditions not limited to trauma, infection and neoplasia. An LIFcan be achieved via posterior approaches, transforaminal interbody Fusion[TLIF] and posterior lumbar interbody fusion [PLIF], and the anterolateralapproaches, anterior lumbar interbody Fusion [ALIF], transpsoas lateral lumbarinterbody Fusion [LLIF] and oblique lumbar interbody Fusion [OLIF]. Posteriorapproaches disrupt the posterior tension band, cause iatrogenic injury toparaspinal musculature, and have limited endplate exposure restricted by thecalsac and nerve roots, which may cause difficulty in correcting coronal imbalanceand lordosis restoration.
The indications of OLIF haveexpanded overtime to include a wide spectrum of degenerative disorders fromsingle level lumbar pathology to multilevel adult degenerative scoliosis (ADS).Large sized spacers are thought to be effective in restoring sagittal andcoronal balance of patients in ADS. For a spine surgeon, clear understanding ofthe local anatomical features and surgical corridors help in achieving a goodoutcome.
The Objectives of the study are :
To measure OLIF operative windows from L2–L3 to L4–L5level in normal patients and patients with ADS.
To assess various anatomical changes that determine thefeasibility of OLIF technique following MRI based morphometric evaluation inADS
