Abstract:
Objective To discuss the effectiveness of the second surgical procedure of adjacent segment degeneration after the first spinal fusion.Method 35 patients who had been performed spinal fusion in our hospital or had symptoms recurred or aggravated after 12 ~ 114 (42 ±35) months of the prior surgery were enrolled in this study.A second surgery was performed and intraoperative the intradiscal pressure of adjacent segments of degeneration and normal segments was measured.The VAS score systems were compared among prior surgery,3 months later and 2 years after the second surgery.Result The intradiscal pressure of adjacent segments after the cervical vertebra and lumbar vertebra fusion were [ (15 ± 4.6)cmH2O,(23 ±5.2)cmH2O],much higher than normal segments [ (3 ±2.3)cmH2O,(8 ±4.1)cmH2O](P <0.01).The VAS score systems of 3 months later and 2 years after the second surgery were [ (2.9 ±0.7),(2.0 ± 0.6) ],which were dramatically lower than the prior (7.8 ± 1.2) (P < 0.01).In 12 ~ 46(31 ± 12) months of follow-up after the second procedure,X-ray and MRI showed that fusion segments reached nearly bone fusion,well decompressed and without nerve compression or other complications.Conclusion If recurrence of symptoms after spinal fusion were caused by adjacent segment degeneration,reoperation would guarantee good clinical outcome.
