A spine surgeon can determine whether someone is a good candidate for two-level cervical disc replacement by reviewing imaging and testing reflexes to identify which discs are symptomatic.
For example, degeneration in the C5-6 disc may present with issues controlling the thumb and biceps, while degeneration in the C6-7 disc can lead to symptoms when controlling the triceps or when affecting sensation in the index and middle fingers.
This neurologic approach is a helpful way to determine the severity of degeneration. In most cases, if a patient shows degeneration in two (even if one disc is more symptomatic than the other), it makes sense to replace both.
Dr. Lanman is highly experienced in performing two-level cervical disc replacement. If you've been told you need a fusion at multiple levels, a consultation can help you understand whether motion preservation is an option for you.
