腰部椎間板ヘルニアの一手術術式について

抄録

We introduce the new operation technic, “osteoplastic median iaminectomy and wire fixation (Takeda)”.
Indications:
1) Median and bilateral herniation
2) Suspicion of cauda tumor
3) Intradural operation
Technics:
1) without resection of the intervertebral joint including total spinous process, triangular osteotomy is performed on the both sides of the lamina which are removed temporarily.
2) Ligamentum flavum is dissected for the widening of the operation field. After the nucleotomy, the lamina is brought in the same region.
3) The apex of the spinous process and the basis of the superior and inferior spinous process are sutured by the wire for the fixation.
We consider this opetarion technic would be very beneficial for several points, which are widening of the operation field, accurate osteoplastic and good course after the operation.
