Study Design : Retrospective study.
Objectives : To determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical myelopathy.
Summary of Literature Review : The postsurgical outcomes were worse from trauma in patients who had a cervical ossification of the posterior longitudinal ligament (OPLL) or cervical canal stenosis, in comparison with patients who did not.
Materials and Methods : The study was conducted on 70 patients who had undergone surgery due to cervical myelopathy from January 2004 to December 2013 and had at least 1 year of follow-up. Depending on trauma history, the patients were divided into two groups, and their radiological (simple radiographic, computed tomographic, and magnetic resonance imaging) and clinical (Japanese Orthopaedic Association [JOA] score, motor power of upper extremities) results were compared retrospectively.
Results : Among 70 patients in total, 18 patients were in the trauma group and 52 were in the non-trauma group, and all cases in the trauma group had a history of minor trauma (11 cases of drivers traffic accidents, 4 cases of slipping and falling, 2 cases of minor pedestrian accidents, and 1 case of falling). Radiologically narrower diameter of the spinal canal showed statistically significant difference between two groups (p=0.042). The JOA scores before and after surgery and the recovery rate did not have a clinically meaningful difference with trauma. However, the degree of motor improvement was significantly higher for the trauma group within 1 week after surgery (p=0.040).
Conclusions : Minor trauma itself may adversely affect the patients' clinical courses.
