Long Term Clinical Outcome of Single Open Door Laminoplasty With Preservation of Unilateral Muscular Ligament Complex

To collect and measure the preoperative and postoperative clinical data of the patients undergoing single open-door expansive laminoplasty with preservation of musclar ligament complex through posterior cervical approach in our hospital and summarize the long-term clinical effect and postoperative imaging changes and analyze the long-term clinical effect of this operation

Objective: To collect and measure the preoperative and postoperative clinical data of the patients undergoing single open-door expansive laminoplasty with preservation of musclar ligament complex through posterior cervical approach in our hospital. To summarize the long-term clinical effect and postoperative imaging changes and to analyze the long-term clinical effect of this operation on cervical spondylosis. To provide scientific basis for clinical work and theoretical research in the future.

This study was a retrospective study, and the medical records of posterior cervical open-door expansive laminoplasty with musclar ligament complex preservation in the orthopedics department of our hospital from 2006 to 2017 were collected, and the patients with complete diagnosis and treatment data were selected for analysis and research.The preoperative and postoperative changes of the patients were studied by combining the patient's case and imaging examination (MR, CT, X plain film) and other diagnosis and treatment data.
