Adjacent-segment degeneration is a known consequence of spinal fusion. Factors associated with this, and its effect on results, have not been well identified. This study sought to determine factors associated with adjacent-segment degeneration and the effect this degeneration has on results after lumbar fusion and instrumentation. Forty-nine patients were retrospectively reviewed after lumbar fusion with instrumentation and analyzed for adjacent-segment degeneration. Adjacent-segment degeneration occurred in 17 (35%) patients and was associated with increasing patient age, the use of interbody fusion, and a worsening of clinical results with time. In older patients with stenosis, it was associated with previous surgery. This should be considered when choosing operative techniques in treating lumbar pathologic conditions, especially in older patients.
相邻节段退变是脊柱融合术的一个已知后果。与之相关的因素及其对手术效果的影响尚未得到充分明确。本研究旨在确定与相邻节段退变相关的因素，以及这种退变对腰椎融合内固定术后效果的影响。对49例行腰椎融合内固定术的患者进行回顾性分析，以评估相邻节段退变情况。17例（35%）患者发生相邻节段退变，其与患者年龄增加、采用椎间融合以及临床效果随时间恶化有关。在老年狭窄患者中，相邻节段退变与既往手术有关。在选择治疗腰椎疾病的手术技术时，尤其是老年患者，应考虑到这一点。
