Abstract:

BACKGROUND: Morbid obesity can result in lumbar and spinal degeneration, especially the lumbar spine degeneration. Related studies have shown that morbid obesity may increase complications of the lumbar fusion, especially wound infection.
OBJECTIVE: To analyze whether morbid obesity can alter the rates of complications in patients undergoing lumbar fusion.
METHODS: 268 patients (including normal weight patients and morbid obese patients) undergoing lumbar single segment fusion were selected as samples. The lumbar and spinal fusion was divided into two types: anterior lumbar fusion and posterior lumbar fusion. The cancellous bone with autologous anterior superior iliac spine was treated with intervertebral bone grafting, and fixed with Medtronic Sofamor titanium rod. The detection found that there was no bone fragments crumbs backward in the anterior dura mater, then the drainage was placed in the incision and closed layer by layer. Symptomatic treatment was performed to prevent infection after lumbar fusion, and the data of the different complications were statistically analyzed.
RESULTS AND CONCLUSION: Among total 268 patients, 104 patients were morbidly obese. The complications of morbidly obese patients included cardiac, renal, pulmonary and wound complications, among them, wound and pulmonary complications were the main complications. There were significant differences in the complications between normal weight patients and morbidly obese patients (P < 0.05). There were no significant differences in the rates of complications between anterior lumbar fusion and posterior lumbar fusion (P > 0.05). Morbid obesity increases the risk of complications in lumbar and spinal fusion surgery, but has no different effects between the patients with anterior lumbar fusion and posterior lumbar fusion.
