The functional and clinical results of anterior interbody lumbar fusion were assessed in 134 patients. Functional tests included spinal mobility and isokinetic trunk muscle strength measurements. The score rating system of the Japanese Orthopaedic association (JOA) and the Oswestry disability index were used for clinical evaluation. Functional results revealed decreased spinal flexibility when compared with normal values. A reduction in physical ability was also seen in the isokinetic trunk muscle measurements. Non-union seemed to have only little effect on the functional results. Patients under 20 years at operation had the best results, but beyond this threshold results did not vary with age. The JOA rating score was 25 or more in 50% of patients. The mean Oswestry disability index was 47.8 (range 1-82) preoperatively and 20 (range 0-68) at follow-up (P < 0.001), indicating a clear decrease in subjective disability. Solid fusion was seen in 107 patients (80%) at follow-up.
对134例患者进行了腰椎前路椎间融合术的功能和临床效果评估。功能测试包括脊柱活动度和等速躯干肌力测量。采用日本矫形外科学会（JOA）评分系统和Oswestry功能障碍指数进行临床评估。功能结果显示，与正常值相比，脊柱灵活性降低。等速躯干肌力测量中也发现身体能力下降。不融合似乎对功能结果影响很小。手术时年龄在20岁以下的患者效果最佳，但超过这个界限，结果并不随年龄变化。50%的患者JOA评分为25分或更高。术前Oswestry功能障碍指数平均为47.8（范围1 - 82），随访时为20（范围0 - 68）（P < 0.001），表明主观功能障碍明显减轻。随访时107例患者（80%）实现了牢固融合。
