Abstract:
[Objective]To observe and analyze the clinical results of ossification of posterior longitudinal ligament(OPLL) combined with high-signal intensity zone(HIZ) change. [Methods]Forty patients with OPLL combined with HIZ were treated from March 2004 to March 2008.Anterior approach surgery was given to 19 cases as group A and posterior approach surgery was given to 21 cases as group P.All cases were followed up.The pre-and post-operative JOA17 scores and improvement ratio were evaluated.[Results]The mean follow-up time were(19.5?3.4) months in group A and(20.3?4.5) months in group P.The mean improvement ratio were(56.2?8.4)% in group A and(52.2?12.2)% in group P.There were no statistical differences between those of groups A and P.Mean JOA scores at last follow-up were(12.8?0.9) in group A and(11.5?1.6) in group P,with significantly difference.[Conclusion]Treatment of OPLL combined with HIZ is a high risk procedure with limited recovery in neoro-function.Good surgical result could be got with correct judgement of type and location of OPLL,occupation ratio of spinal canal and selection of approach.
