Objective To observe the morphological characteristics of basivertebral foramen (BVF) in patients with osteoporotic vertebral compression fracture (OVCF). Methods One hundred and seven cases of lumbar OVCF patients were studied. The number and morphology of BVF were observed on CT images. The basivertebral foramen width (BFW), basivertebral foramen depth (BFD), basivertebral foramen height (BFH), BFW relative value (BFWr), BFD relative value (BFDr), BFH relative value (BFHr), left vertebral body width (VWL), right vertebral body width (VWR), vertebral body up (VHU) and vertebral body below (VHB) were measured. All the data were analyzed by SPSS25.0 software. Results Most BVF were single-hole type, rectangular on coronal images and triangular or trapezoidal on horizontal images. The average width of BVF was (7.8±1.6) mm, average depth was (12.4±2.1) mm and average height was (5.4±1.1) mm. The average width, depth and height of BVF respectively accounted for 1/5, 2/5 and 1/4 of the vertebral body width, depth and height. There was no statistical difference between VWL and VWR in L1 and L3 (P>0.05), but there were statistical differences between VWL and VWR in L2, L4 and L5 (P<0.05). There were statistical differences between VHU and VHB (P<0.05), and BVF was closer to the upper endplate. Conclusions The puncture target position and amount of bone cement are determined in surgery according to the morphological characteristics and anatomical data of BVF, which is beneficial for preventing bone cement leakage.
