Abstract:
ObjectiveTo explore puncture point and angle of skin for unipedicular vertebroplasty by imaging measurement and combining clinical practice in order to pr vide reference for clinical work.MethodsCT images of thoracic and lumbar vertebrae of imaged with multislice helical CT were random chosen.From high to low position vertebrae of easy fracture T6 to -L5,its angle between vertebraI pedfcle stalk line and 1/3 of vertebraI body stalk line fore and median of point of intersection was measured.The angle of sternocostal joints route was also measured.At the same time the distance between site of skin puncture and spinous process was measured.ResultsThe angle between the thoracic vertebraI pedicle and sagittal section was (28.2 ± 3.8) °,the lateral distance of the spinous process was ( 31.6 ± 5.4) mm.The angle of thoracic vertebraI pedicle lateral route was (35 ± 3.4) °,the distance was ( 55.2 ± 5.3 ) mm.In the lumbar vertebrae pedicle route,the angle of L1 -L4 was (29.3 ± 5.6 ) °,the distance was (38.4 ± 4.5 )mm.Ls was (39.2 ± 3.3) °,the distance was ( 71.6 ± 6.2) mm.Combining clinical practice,the lateral distance of the spinous process in thoracic vertebraIpedicle route,the best puncture point was 30 mm,in thoracic vertebraI pedicle lateral route it was 40 mm,in L1-L4 it was 45 mm,in L5 it was 60 mm.ConclusionsThe unipedicular vertebroplasty can be performed rapidly,accurately and safely,and it reduces complications,cost and time.
