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。
