Hypothesis
To investigate the clinical effects and operational points of Bryan cervical disc prosthesis in Chinese patients with cervical spondylotic myelopathy.
Conclusion
Bryan cervical disc prosthesis restored motion and achieved good stability and treatment effects in patients with cervical spondylotic myelopathy.
Supporting Evidence
- All patients showed improvement according to Odom's scale.
- JOA score increased from an average of 8.7 to 15.5.
- No prosthesis subsidence was observed.
- The replaced segment achieved stability and restored partial normal range of motion.
Takeaway
Doctors replaced discs in people's necks to help them move better and feel less pain, and it worked well for most of them.
Methodology
A prospective non-random clinical and radiographic study involving 83 patients who underwent Bryan disc prosthesis replacement.
Potential Biases

Limitations
The study was not randomized and had a limited follow-up period for some patients.
Participant Demographics
43 males and 40 females, average age 48.9 years.
