Abstract:
[Objective] To observe the clinical effect of Bryan cervical prosthetic disc in treating ossification of posterior longitudinal ligament(OPLL)of cervical spine.[Method]From October 2005 to June 2007,15 localized OPLL patients were treated surgically by cervical arthroplasty using Bryan disc prosthesis.JOA score and radiological study were performed before and after operation.The range of movement(ROM)of replaced level were investigated postoperatively.[Result]Neurological deficit was alleviated in all patients.All patients were followed up at least 6 months,JOA score increased from an average of 8.5 to 15.8.Replaced segment restored the normal ROM in flexion and extension.[Conclusion]Cervical arthroplasty using Bryan disc prosthesis can achieve good clinical outcome in treating localized OPLL of cervical spine;and the normal ROM can be retained in the replaced level.
