Abstract
Objectives: We discuss the incidence of postoperative kyphosis following laminoplasty and its impact on outcomes, as well as critical radiographic parameters, intraoperative technical factors, and postoperative protocols that can be used to improve results.
Summary of background data: When appropriately selected, cervical laminoplasty is a motion-sparing treatment option for cervical myelopathy and is a valid alternative to laminectomy and fusion procedures. However, like other posterior-based cervical decompression techniques, laminoplasty can cause postoperative kyphosis.
Methods: A PubMed search was performed to gather articles that focus on cervical deformity in the context of cervical laminoplasty.
Results: The reported conversion rates of lordotic to kyphotic cervical alignment after laminoplasty range from 5.2% to 11.3%. Kyphosis likely reduces the benefit from the operation as measured by postoperative mJOA scores. A surgeon can minimize the risk of causing a clinically significant reduction in lordosis by screening out patients with certain radiographic characteristics. Intraoperative decisions such as dissection techniques, levels chosen, and hybrid constructs can preserve the cervical tension band. Certain postoperative protocols can improve cervical posture.
Conclusions: Cervical laminoplasty is an effective tool for treating degenerative cervical myelopathy. Careful radiographic screening, intraoperative decision-making, and postoperative protocols can minimize the development of postoperative cervical deformity and improve outcomes.
期刊介绍：
Clinical Spine Surgery is the ideal journal for the busy practicing spine surgeon or trainee, as it is the only journal necessary to keep up to date with new clinical research and surgical techniques. Readers get to watch leaders in the field debate controversial topics in a new controversies section, and gain access to evidence-based reviews of important pathologies in the systematic reviews section. The journal features a surgical technique complete with a video, and a tips and tricks section that allows surgeons to review the important steps prior to a complex procedure.
Clinical Spine Surgery provides readers with primary research studies, specifically level 1, 2 and 3 studies, ensuring that articles that may actually change a surgeon’s practice will be read and published. Each issue includes a brief article that will help a surgeon better understand the business of healthcare, as well as an article that will help a surgeon understand how to interpret increasingly complex research methodology. Clinical Spine Surgery is your single source for up-to-date, evidence-based recommendations for spine care.
