What is Thumb CMC Joint Denervation?
Thumb carpometacarpal (CMC) arthritis can cause pain at the base of the thumb, making everyday activities such as gripping, pinching, and opening jars difficult.
Thumb CMC joint denervation is a surgical procedure that removes the nerves responsible for carrying pain signals from the thumb CMC joint to the brain. Unlike thumb CMC arthroplasty, this procedure does not remove the arthritic joint itself. Instead, it is designed to reduce pain while preserving the existing joint.
For selected patients, CMC joint denervation may provide pain relief with a shorter recovery than thumb CMC arthroplasty.
Thumb CMC Joint Denervation Procedure
During CMC joint denervation, the surgeon identifies and removes the nerves that transmit pain signals from the thumb CMC joint. Recovery from this procedure is typically shorter than recovery after thumb CMC arthroplasty. Most patients recover in approximately three to four weeks.
Before surgery, your surgeon will explain the procedure, answer your questions, and discuss whether this treatment is appropriate for your condition.
Frequently Asked Questions
When is thumb CMC joint denervation recommended?
CMC joint denervation may be considered for selected patients with thumb CMC arthritis who are interested in a shorter recovery than thumb CMC arthroplasty.
What happens during thumb CMC joint denervation?
During the procedure, the surgeon identifies and removes the nerves that carry pain signals from the thumb CMC joint.
How is CMC joint denervation different from thumb CMC arthroplasty?
CMC joint denervation removes the nerves that transmit pain from the joint, while thumb CMC arthroplasty removes the arthritic trapezium bone and reconstructs the joint. Your surgeon will discuss which procedure is most appropriate for your condition.
How long does recovery take?
Recovery following CMC joint denervation is typically shorter than recovery after thumb CMC arthroplasty. Most patients recover in approximately three to four weeks.
What results can I expect from CMC joint denervation?
CMC joint denervation may reduce pain caused by thumb CMC arthritis. However, long-term outcomes are not yet known, and results are considered less predictable than those of thumb CMC arthroplasty.
Can I have another procedure if my symptoms return?
Yes. Some patients may undergo a repeat denervation procedure or later choose to proceed with thumb CMC arthroplasty if symptoms persist or return.
Is Joint Denervation Right for You?
CMC joint denervation may be appropriate for selected patients with thumb CMC arthritis who are interested in a shorter recovery period than thumb CMC arthroplasty. When recommending treatment, your provider will consider:
- Your symptoms
- Your activity level
- Your treatment goals
- Your expectations for recovery
It is important to understand that the long-term outcomes of CMC joint denervation are less predictable than those of thumb CMC arthroplasty.
