Abstract

The author main objective was to improve the previously developed technique of split laminotomy and moderate enlargement of the spinal canal with preservation of the majority of posterior structures, and to avoid the complications of the classic autologous bone grafting procedure. A multilevel spinous process splitting and distracting laminotomy technique with complementary spacer insertion between the laminar parts was developed. We used Poly-Ether-Ether-Ketone (PEEK) cages. This improved method was used in five patients to remove malignant intramedullary tumors at the thoracic level. Adequate surgery of the tumors located intramedullary, and permanent decompression of the spinal canal was achieved in all patients using our new modified procedure. The results have been postoperatively confirmed with MRI and CT. The affected spine was the thoracic in all cases. The numbers of split laminae were three to five. Histological results were as follows: four intramedullary astrocytomas, one ependymoma. The ependymoma was completely, while the astrocytomas were only subtotally removed. In all cases heterologous grafts were inserted between the sides of the distracted laminas, to achieve the enlargement of the spinal canal. The mean dur...Continue Reading
