At last, ILIF in segment L3-4 and L4-5 is feasible. 2. There are enough operation space for ILIF in L3-4 and L4-5 with the root being retracted gently. And it is feasible to insert a couple transpedicle screws homolaterally. The intertransverse area was too narrow to perform ILIF on L5-S1.3. ILIF provide greater biomechanical stability than TLIF. while there was no significantly different stability between ILIF with homolateral or bilateral pedicle screw fixation. Adequate postoperative stability can be achieved by intertransverse lumbar interbody fusion with homolateral pedicle screw fixation.4. ILIF with transpedicle screws fixation homolaterally was a safe, convenient and effective operation, and less intraspinal complications were occurred of ILIF than TLIF.5. The fusion condition was satisfaction in ILIF group, which was better than TLIF group.

横突间入路腰椎椎体间融合术在L3-4、L4-5节段具有可行性。2、在L3-4、L4-5节段可提供足够的空间行ILIF手术，并可通过同一切口附加椎弓根钉固定，操作安全、简便。L5-S1节段横突间区域较小，操作困难，不适合行ILIF手术。3、ILIF手术术后生物力学稳定性有所下降但优于TLIF手术；ILIF附加同侧椎弓根钉固定与附加双侧椎弓根钉固定生物力学稳定性相当，使用ILIF术式附加侧同椎弓根螺钉固定，可提供较好的即刻稳定性。4、ILIF手术及附加同侧椎弓根钉固定是一种安全、简便、有效的手术方式，在减少椎管内并发症方面具有优势。5、ILIF手术可获得较好的融合率，其融合情况从组织学观察稍好于TLIF手术。

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。
