Abstract:
ObjectiveTo observe the morphological features of the basivertebral foramen (BF) in thoracolumbar (T12,L1,L2 and L3).MethodsA total of 36 health adults were underwent multi-slice CT thin slice scans and three-dimensional reconstruction.In the horizontal and sagittal CT reconstruction images,BF weight (BFW),BF depth (BFD),BF high (BFH),BF relative to the body weight (BFWr),BF relative to the body depth (BFDr),and BF relative to the body high (BFHr),were measured.The distance between the BF and each side in the horizontal and sagittal CT images were also measured.The correlation between the measured parameters of BF and the gender,age,body mass index(BMI) were analyzed statistically.Results 81％ BF was triangular or trapezoid.There was a bone interval within 6％ BF.In the same level in 36 cases,the maximum of BFW,BFD and BFH were approximately 1/3 vertebral body in the same plane.The average BFW,BFD and BFH were approximately 25％ vertebral body in the same plane.In all four levels,the distance from the BF to the cranial endplate was shorter than to the caudal endplate (P＜O.05).The mean BFW,BFH,BFWr,BFHr in different levels were no significant difference(P＞0.05).The mean BFD and BFDr in L3,however,were greater than other levels.There were no significant correlations among gender and BFW,BFWr,BFD,BFDr,BFH,BFHr.There was a correlation between the age and L1BFHr and L2BFHr,and a correlation between BMI and L1BFH,L2BFW,L3BFH and L3BFHr.ConclusionThere was a BF in all specimens.The most common appearance of BF was triangular or trapezoid.BF was closer to the cranial endplate in all four levels in the sagittal CT images.Variations of BF were significantly different in individuals.
