There may be biomechanical changes in the adjacent hip joint after lumbosacral fusion. The literature has limited information on how these biomechanical changes may result in hip joint space.
METHOD: Our retrospective study examined hip joint space narrowing in patients who underwent lumbosacral fusion between 2020 and 2022. In addition, spinopelvic parameters such as sacral slope, the sagittal vertical axis, pelvic incidence, lumbar lordosis, and pelvic tilt were compared in patients who underwent short-segment (up to three levels, S group) and long-segment (4 and higher levels, L group) fusions.
Our study found no significant relationship between spinopelvic parameters and joint space narrowing in the S and L groups. In addition, it was determined that there was more narrowing in the hip joint space in the long-segment group, and there was a positive correlation between the segment length and the narrowing in the hip joint space.
After lumbosacral fusion, narrowing of the hip joint space was observed. Particularly patients with long-segment lumbosacral fusion should be followed closely regarding hip osteoarthritis risk.
腰骶融合后，相邻髋关节可能会发生生物力学变化。文献中关于这些生物力学变化如何导致髋关节间隙变窄的信息有限。
我们的回顾性研究检查了 2020 年至 2022 年间接受腰骶融合的患者的髋关节间隙变窄情况。此外，比较了接受短节段（最多三个节段，S 组）和长节段（4 个及以上节段，L 组）融合的患者的脊柱骨盆参数，如骶骨倾斜度、矢状垂直轴、骨盆入射角、腰椎前凸和骨盆倾斜度。
我们的研究发现 S 组和 L 组的脊柱骨盆参数与关节间隙狭窄之间没有显著关系。此外，长节段组髋关节间隙变窄更明显，并且髋关节间隙狭窄与节段长度之间存在正相关关系。
腰骶融合后观察到髋关节间隙变窄。特别是对于接受长节段腰骶融合的患者，应密切关注髋关节骨关节炎的风险。
