OBJECT: The authors evaluated an alternative method to avoid postoperative posterior tethering of the spinal cord following resection of @entity424 . METHODS: Twenty-five @entity1 with @entity424 underwent surgery between 1978 and 2002. There were 16 male and nine female @entity1 whose ages at the time of surgery ranged from 14 to 64 years (mean 41.8 years). The follow-up period ranged from 6 to 279 months (mean 112.4 months). In the initial 17 @entity1 (Group A), the procedure to prevent @entity2443 consisted of the layer-to-layer closure of three meninges and laminoplasty. In the subsequently treated eight @entity1 (Group B), the authors performed an alternative technique that included pial suturing, dural closure with Gore-Tex membrane-assisted patch grafting, and expansive laminoplasty. In Group A, @entity86 was radiologically detected in eight cases (47%), and delayed @entity16 secondary to posterior tethering of the cord was found in five cases. In Group B, there was no evidence of adhesive posterior tethering or delayed @entity16 . A significant intergroup statistical difference was demonstrated for radiologically documented posterior tethering (p < 0.05, Fisher exact test). Moreover, @entity1 with radiologically demonstrated posterior tethering suffered a significant delayed neurological functional deterioration (p < 0.01, Fisher exact test). CONCLUSIONS: This new technique for closure of the surgical wound is effective in preventing of postoperative posterior spinal cord tethering after excision of @entity424 .
