Objective:

To review the effect of obesity on the effectiveness of posterior lumbar fusion in patients with lumbar degenerative diseases (LDD).

Methods:

The related literature at home and abroad was extensively reviewed. And the difficulty of operation, risk of complications, and long-term effectiveness of posterior lumbar fusion for obese patients with LDD were summarized.

Results:

Although some relevant literature suggest that the posterior lumbar fusion for obese patients is difficult and the risk of postoperative complications is high, the overall research results do not suggest that obesity is a risk factor for the implementation of posterior lumbar fusion. By assessing the physical condition of patients and strictly grasping the surgical indications, obese patients can obtain good surgical efficacy.

Conclusion:

Posterior lumbar fusion is an effective method for the treatment of LDD in obese patients. However, relevant studies need to be completed to further evaluate the safety and efficacy of posterior lumbar fusion for obese patients.

目的:

综述肥胖对腰椎退变性疾病（lumbar degenerative diseases，LDD）患者后路腰椎融合术疗效的影响。.

方法:

广泛查阅近年国内外相关文献，总结肥胖 LDD 患者行后路腰椎融合术治疗的操作难度、并发症发生风险及远期临床疗效。.

结果:

虽然有相关文献提示肥胖患者后路腰椎融合术操作难度大，术后并发症发生风险高，但总的研究结果并未提示肥胖是施行后路腰椎融合术式的危险因素。通过评估患者身体状况，严格把握手术指征，肥胖患者能够获得良好手术疗效。.

结论:

后路腰椎融合术是治疗肥胖 LDD 的有效手段，但相关研究仍需完善，以进一步评估肥胖患者后路腰椎融合术的安全性和有效性。.
