This surgical approach fulfills the requirements of other [[laminotomy]] techniques and helps prevent damage to the crucial posterior stabilizers of the spine. In contrast to conventional spinal canal approaches, preservation of the majority of posterior structures leaves muscle attachments on the spinous processes and laminae completely intact. Furthermore, the technique for exposure and decompression of the spinal canal is a suitable method for all spinal segments, the cervical, thoracic, and the lumbar spine in all age groups ((Banczerowski P, Vajda J, Veres R.

canal using split laminotomy and its modification, the "archbone" technique.

A modification of the split laminotomy and heterologous grafting method fulfills the requirements of other laminotomy techniques. The split laminotomy is suitable for removing intramedullary tumors, and the posterior stabilizing structures of the spine, as the vertebral laminae and the longitudinal musculature are completely prevented. Due to use of allograft the complications of the classic hip bone grafting procedures are avoided. The spacers, inserted between the osteotomized faces, provided permanent decompression of the spinal canal, and bony healing--throughout the spacer--of the splitted vertebral laminae, without iliac graft complications
