[Functional evaluation of the cervical spine after Bryan artificial disc replacement]

Area of Science:

• Spine surgery
• Biomechanical engineering
• Orthopedics

Context:

• Cervical disc replacement is a surgical procedure to treat degenerative disc disease.
• The Bryan cervical artificial disc is designed to preserve motion in the cervical spine.
• Assessing the long-term functional outcomes of cervical disc replacement is crucial for patient management.

Purpose:

• To evaluate the functional outcomes of Bryan cervical disc replacement.
• To assess the range of motion in the sagittal plane of the operated disc and adjacent levels.
• To determine patient satisfaction and complication rates following the procedure.

Summary:

• Bryan cervical artificial disc replacement was performed in 164 patients.
• Postoperative range of motion in the operated segment was maintained, while adjacent segment motion was reduced but stable.
• High patient satisfaction (94%) and a 56% improvement in JOA score were reported, with low complication rates.

Impact:

• Bryan artificial disc replacement demonstrates good clinical outcomes and maintains cervical spine function.
• The procedure offers a viable option for treating cervical degenerative disc disease.
• Findings support the use of Bryan artificial disc replacement for preserving sagittal motion.
