Lumbar laminoplasty
Despite the fact that microsurgical lumbar laminoplasty is an effective and less-invasive method for decompressing spinal nerves compared to traditional laminectomy, few surgeons have adopted it because the technique is more time-consuming and requires specialized training and equipment (operating microscope).
In 1981, Getty et al. 1) performed a prototype of partial undercutting facetectomy for LSS to provide stability during nerve root decompression. A long-term, retrospective study of 57 patients who underwent the facet-sparing surgery was performed 2)
