Background: The authors describe their experience with a modified version of the standard technique of open-door laminoplasty for the surgical treatment of spondylotic myelopathy in elderly patients with temporary removal of the laminae, extensive decompression, and pre-plating of the laminae beyond the surgical field.
Methods: Description of surgical anatomy, surgical technique, indications, limitations, complications, and specific perioperative considerations, as well as specific information to give to the patient about surgery and potential risks. A summary of ten key points is given.
Conclusions: Transection of the laminae on both sides (temporary laminectomy) and pre-plating of the laminae outside of the surgical field has several advantages: better decompression of the spinal canal and the neuroforamina on both sides, easier undercutting of adjacent vertebral arches for cranio-caudal decompression, and no risk of spinal cord injury by the screwdriver when attaching plates to the laminae.
