Abstract:
[Objective]To evaluate the clinical result after treatment of disc herniation with the Bryan cervical disc prosthesis.[Method]There were 14 cases with cervical disc herniation.There were 4 females and 10 males with ages ranging 31~52 years(mean age 43 years).The herniated disc located at C_(3、4) in 2 cases,C_(4、5) in 2 cases,C_(5、6) in 8 cases,C_(4~6) in 1 case and C_(3~6) in 1 case.A total of 16 Bryan cervical disc prosthesis were implanted.Single level disc was replaced in 12 cases while hi-level in 2 cases.The Bryan Cervical Disc prosthesis contains a proprietary,low-friction,wear-resistant,unmique polyurethane nucleus.The nucleus was articulated with shaped titanium plates(shells)that include convex porous ingrowth surfaces,to allow bony fixation to the adjacent vertebral endplates.The stabilization and range of motion at the implanted level were observe red on dynamic radiograph postoperatively.[Result]The average follow up was 10 months and the longest follow up was 28 months.Neurological symptoms in all cases had significant improvement.The average improvement was 8.5 point according CSM criteria.Effective rate was 100%.There was no prosthesis displacement and loosening in all cases.The ROM at implant level was 6.4 degrees on the flexion-extension radiographs.[Conclusion]There is a definite stabilization and motion after implant of cervical dics prosthesis.A functional discs prosthesis is an effective treatment of cervical disc herniation.There is a good early clinical result.The result of long follow up should be observed further
