The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement.

New Zealand white rabbits (3-4 months old, 3-4 kg weight) were the test animals, and they were divided into three groups proceeding in this study. In group A:One PLLA screw and one commercial screw were implanted in the right tibia. Two PLLA screws were implanted in the left. Furthermore, one PLLA bar was implanted in both right and left tibia respectively with onlay model in group B. Also,one PLLA plate was implanted in the left tibia and one commercial plate in the right respectively with onlay model in group C . Many tests were done on each sample in 1, 4, 8 and 12 weeks which included the observation of tissue response in group A, and the change of three-points bending, weight loss, molecular weight, crystallinity and morphology of fracture surface by scanning electronic microscopyin group B, and the change of three-points bending, weight loss and molecular weight in group C.

所使用实验动物为24只3-4个月大，体重3-4公斤的纽西兰兔，并将所使用材料及动物分为A、B、C三组进行。A组中於实验兔之右胫骨植入两支骨钉，一支为自制骨钉，一支为MacroPore市售骨钉，并钻一孔但不植入骨钉做为控制组；另於实验兔之左胫骨植入两支自制骨钉，另标示一区不钻孔不植入骨钉做为控制组。B组采用onlay1 模式於实验兔之左右胫骨各植入一自制长型片。C组也采用onlay模式於实验兔之左胫骨植入一自制骨板，於右胫骨植入一市售骨板，各於不同时间点( 1， 4及12周)将A及C组，而於( 1，4，8及12周)将B组内的植入物取出进行各种测试，包括A组的组织切片观察及B组的三点弯曲变化、质量损失、分子量变化、结晶度变化及扫描式电子显微镜观察断面型态改变及C组的三点弯曲变化、质量损失、分子量变化。

The optimal entrance point mostly locate at the root of accessoryprocess which adjacent to the mamillary process from L1 to L4, Theadjustable range of entrance points of the 4 segments almost cover theaccessory process, But at L5, The optimal entrance point is much moreoutside away from the accessory process, just at the middle of thetransverse process and the adjustable range of entrance points islimited.

这与钉尾间距的明显变化相一致，手术时应注意调整螺钉钉尖内偏角度观察椎弓根螺钉进钉点发现内外侧螺钉进钉点与内上、外上螺钉进钉点构成接近矩形的梯形区域，最佳进钉点居于内外进钉点中部。L1到L4最佳进钉点位于副突根部靠近乳突处，随着椎体节段下降，进钉点逐渐移向外侧，L1最佳进钉点基本在副突根部骨嵴内侧缘，L2、L3最佳进钉点基本在副突根部骨嵴上，L4最佳进钉点基本在副突根部骨嵴外侧缘。L1到L4可选进钉点范围几乎均包含副突骨嵴。L5最佳进钉点则明显偏外，多数位于副突根部与横突外端连线的中内1／3。
