To assess the radiographic results in patients who underwent transforaminal lumbar interbody fusion (TLIF), particularly the changes in segmental lordosis in the fusion segment, whole lumbar lordosis and disc height.
Twenty six cases of single-level TLIF in degenerative lumbar diseases were analyzed. The changes in segmental lordosis, whole lumbar lordosis, and disc height were evaluated before surgery, after surgery and at the final follow-up.
The segmental lordosis increased significantly after surgery but decreased at the final follow-up. Compared to the preoperative values, the segmental lordosis did not change significantly at the final follow-up. Whole lumbar lordosis at the final follow-up was significantly higher than the preoperative values. The disc height was significantly higher in after surgery than before surgery (p = 0.000) and the disc height alter surgery and at the final follow-up was similar.
When performing TLIF, careful surgical techniques and attention are needed to restore and maintain the segmental lordosis at the fusion level.
评估经椎间孔腰椎体间融合术（TLIF）患者的影像学结果，特别是融合节段的节段性前凸、整个腰椎前凸和椎间盘高度的变化。
分析了 26 例退变性腰椎疾病的单节段 TLIF。在术前、术后和末次随访时评估节段性前凸、整个腰椎前凸和椎间盘高度的变化。
术后节段性前凸明显增加，但在末次随访时下降。与术前相比，末次随访时节段性前凸无明显变化。末次随访时整个腰椎前凸明显高于术前。术后椎间盘高度明显高于术前（p = 0.000），且术后和末次随访时的椎间盘高度相似。
行 TLIF 时，需要仔细的手术技术和注意，以恢复和维持融合水平的节段性前凸。
