[The relation between cord compression rate and the outcome of surgical treatment]
1Department of Orthopaedics, Frist Hospital of Beijing Medical University, Beijing 100034.
Objective:
To study the relation of compressive spinal cord changes in morphology with postoperative results.
Methods:
114 cases of operative patients were divided in to three groups: ossification of posterior longitudinal ligament (OPLL), cervical spondylotic myelopathy (CSM), and cervical intervertebral disc herination. The spinal cord plane and to the compressive ratio in the most heavily pressed position were measured according to the JOA record.
Results:
The compressive ratio and the plane were not corelated with clinical history. The spinal cord plane was positively corelated with the recovery rate.
Conclusions:
The preoperative spinal cord plane in OPLL and CSM is mostly corelated with the recovery rate.
