A Guide After Thumb CMC Arthroplasty Surgery

Recovery after a Carpometacarpal (CMC) arthroplasty, just like any surgery, can be quite the experience…and it is always better to go in prepared! Whether you're in the initial stages of post-operative care or well into the recovery process, understanding the challenges and adopting adaptive tools can significantly improve your journey toward increased functionality. Let’s chat about the phases of recovery after CMC arthroplasty, the role of splints, and various adaptive tools that can aid in regaining hand function.

Understanding CMC Arthroplasty Recovery:

CMC arthroplasty is a surgical procedure designed to address arthritis in the base of the thumb. There are several surgical techniques that can be used based on your specific situation. Each surgery has its own restrictions and considerations, but generally follow a similar path.


The recovery process is typically divided into phases, with the initial focus on pain management, wound healing, and gentle mobilization exercises. You may be placed in a custom splint or cast at this time to allow your surgical site to properly heal. As the weeks progress, you will start to be weaned out of the splint and rehabilitation shifts toward movement, strengthening exercises, functional tasks, and adapting to the use of adaptive tools.


The Role of Splints:

A crucial component of early post-operative care is the use of a splint. This serves to provide stability, protect the surgical site, and prevent unwanted movement during the initial healing period. While the duration of splint use varies among individuals, it's essential to follow the recommendations of your surgeon and physical or occupational therapist.


During the splint phase, gentle range-of-motion exercises may be introduced to prevent stiffness, especially at surrounding joints. You want to keep your other fingers and elbow moving to prevent stiffness. This will also help to pump swelling out of your arm. Try to move your other fingers and elbow for 15 repetitions, once and hour. Additionally, maintaining a proper hand position within the splint is crucial for optimal healing and long-term function. As you progress in your recovery, your healthcare team will guide you through the gradual reduction of splint use.


Gaining Strength and Motion:

After you have been given the all clear to start to wean out of your splint, your therapist or doctor will recommend range of motion exercises and stretches to help improve your movement patterns. You will start to tolerate gentle movement and light function but should avoid heavy lifting as you won’t have the strength yet. It is important to remember - you have been locked down in a splint for several weeks, these muscles have not worked in a long time! They are going to get really tired and sore with what seems like very little exercise or activity. That’s OK! They will get stronger every single week. Think about after you have been sick in bed for 3 days. It takes you a week to be able to go up the stairs without being winded. It is the same concept for these small muscles in your hand, they need time to build their endurance up again. Using tools and adaptive equipment can help make you successful during this time while you get stronger!
