Abstract:
[Objective]To compare the treatment effects between posterior single segment fusion or non-fusion in lumbar spinal disease,and to evaluate their influence on adjacent segments.[Method]Thirty-two cases of degenerative lumbar spinal disorders were treated with Coflex(group non-fusion) and PLIF(group fusion),and followed up for over 2 years.The clinical effect was evaluated by visual analogue scale(VAS) and Oswestry disability index(ODI).Range of motion(ROM) of lumbar segments was measured by X-ray film.[Result]In group non-fusion,VAS decreased from 7.8?1.2 pre-operatively to 2.1?0.6 at final follow-up,ODI from 30.8?3.2 to 4.6?1.2,ROM improved significantly.In group fusion,VAS decreased from 7.2?1.1 to 2.0?0.6,ODI from 29.9?3.0 to 4.5?0.9,and ROM of L3、4 improved significantly.No significant difference of clinical effect was found between 2 groups.[Conclusion]Both fusion and non-fusion fixation have satisfying effects in treatment of degenerative lumbar spinal disorder.Non-fusion fixation has less influence on ROM of lumbar segments and could reduce adjacent segment degeneration.
