Thumb arthritis is osteoarthritis at the base of the thumb, where the carpometacarpal (CMC) joint wears down until gripping, pinching, and turning a key become painful. Anti-inflammatory pills can quiet a flare but don’t rebuild cartilage, which is why Hand & Wrist of Louisville starts with splinting, topical treatments, hand therapy, and targeted cortisone injections before surgery enters the conversation. When those options stop helping, Michael C. Nicoson, M.D., offers total thumb arthroplasty, a joint replacement that swaps the worn surfaces for a small dual-mobility implant such as the TOUCH® system. Traditional trapeziectomy removes the trapezium bone and rebuilds the space with a tendon graft, while the implant preserves thumb length and alignment. Recovery begins with early hand therapy and continues across three to six months.

What Is Hand and Thumb Arthritis?
Thumb arthritis is a form of osteoarthritis that develops at the base of the thumb, in the joint hand surgeons call the carpometacarpal (CMC) or basal joint. Over time, the cartilage that cushions the joint wears down, and the bones begin to rub against each other.
The CMC joint is saddle-shaped, which is what lets the thumb pivot, swivel, and pinch. Cleveland Clinic reports that thumb arthritis is the second most common form of arthritis in the hand, after arthritis in the last joint of the fingers.
Opening a jar, turning a key, typing, or holding a coffee mug all put that one small joint under load. As the cartilage thins, ordinary tasks become the moments when the pain shows up.
Typical symptoms include:
- A dull, aching pain at the base of the thumb or near the wrist
- Sharp discomfort when pinching, twisting, or gripping
- Swelling, tenderness, or a bony bump at the base of the thumb
- Grinding or crunching sensations during movement
- Less thumb motion and weaker pinch strength
Risk rises with age 40 and older, and women develop thumb arthritis more often. It also shows up in younger adults with a past thumb injury or a history of repetitive manual work.
Why Do Painkillers Stop Working for Thumb Arthritis?
Painkillers stop working because they treat the pain signal, not the joint. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen calm inflammation during a flare, but no oral medication rebuilds worn cartilage or restores a stable joint surface.
Daily reliance on pain pills carries three specific limits:
- Temporary masking. Oral medication changes how the pain registers without addressing joint instability or bone-on-bone contact.
- Side effects with long-term use. Hospital for Special Surgery notes that NSAIDs carry gastrointestinal risks, including stomach irritation, ulcers, and bleeding; they can affect kidney function and can raise blood pressure.
- Continued joint wear. Masking pain makes it easier to keep overusing an unstable joint, which does nothing to slow the underlying wear.
None of this makes anti-inflammatory medication useless. It makes it a short-term tool, not a long-term plan.
What Nonsurgical Treatments Help Thumb Arthritis?
Nonsurgical care for thumb arthritis centers on resting the joint, calming inflammation, and changing how the hand loads the thumb. Hand & Wrist of Louisville works through these options before surgery becomes part of the discussion.
Custom splinting and bracing. A thumb spica splint holds the CMC joint still and blocks the twisting motions that aggravate it, while the fingers stay free. Wearing the splint during heavy tasks or overnight gives inflamed tissue a chance to settle.
Topical treatments. Anti-inflammatory gels applied over the joint deliver medication where the pain is, with less of it traveling through the rest of the body than an oral pill.
Certified hand therapy. A certified hand therapist teaches joint-protection habits: wider-handled tools, scooping with the palm instead of pinching, and other adjustments that reduce twisting force on the thumb.
Targeted cortisone injections. A steroid injection placed into the CMC joint can quiet a painful flare for several months, and it also helps confirm that the joint itself is the pain source. Cleveland Clinic notes that these injections tend to become less effective the more often they are repeated.
What Is Total Thumb Arthroplasty?
Total thumb arthroplasty is a joint replacement for the base of the thumb in which the damaged joint surfaces are removed and replaced with a small implant, rather than removing the bone entirely. At Hand & Wrist of Louisville, Michael C. Nicoson, M.D., a board-certified plastic and reconstructive surgeon with subspecialty certification in hand surgery, performs the procedure. The TOUCH® thumb implant is a dual-mobility design, meaning it has two moving surfaces rather than one. The design goals are straightforward:
- Preserved anatomy. Joint height and thumb length are maintained rather than shortened, which keeps the mechanics of pinch closer to normal.
- A stable fulcrum. The implant gives the thumb something firm to pinch against, instead of relying on soft tissue to hold the position.
- Stability during motion. The dual-mobility design is intended to allow fluid pivoting while decreasing the risk of implant dislocation.
- Early motion. Because surrounding bone structure is preserved, hand therapy can begin sooner than after procedures that depend on a tendon graft healing first.
Research supports the design rationale. A 2025 study of the TOUCH implant in 78 patients reported restored thumb length, less dislocation and loosening than with earlier single-mobility implants, and 96% of implants still in place at two years.
How Does Thumb Joint Replacement Compare to Trapeziectomy?
Trapeziectomy removes the trapezium, the small wrist bone that forms the socket side of the thumb joint, and fills the gap with a rolled tendon graft. Thumb joint replacement leaves the bone in place and resurfaces the joint instead. Both are established procedures, and the right one depends on bone quality, activity demands, and what matters most to the patient.
| Feature | Traditional trapeziectomy | Total thumb arthroplasty |
| Surgical approach | Removes the trapezium and reconstructs the space with a tendon graft | Resurfaces the joint with an engineered implant |
| Thumb structure | The thumb can shorten slightly as the space settles | Thumb length and alignment are preserved |
| Pinch mechanics | Pinch strength returns gradually as the reconstruction settles | The implant creates a stable fulcrum for pinch |
| Rehabilitation | Longer immobilization while the tendon graft heals | Earlier motion, guided by an in-house certified hand therapist |
| Track record | Decades of long-term follow-up data | Strong short- and mid-term data, with long-term data still accumulating |
The last row carries real weight. Trapeziectomy has the longer published history, while dual-mobility implants have shorter follow-up. Dr. Nicoson reviews both paths during a consultation rather than defaulting to one.
Where Can You Get Thumb Arthritis Treated in Louisville?
Hand & Wrist of Louisville evaluates and treats hand and thumb arthritis in Louisville, Kentucky, and you can request an appointment by calling (502) 409-6898. An evaluation identifies which joint is causing the pain and the stage of arthritis, which determines the options worth discussing.
Dr. Nicoson completed his medical degree at the University of Louisville, a Plastic and Reconstructive residency at Washington University in St. Louis and a hand and microsurgery fellowship at the Mayo Clinic. Whether the goal is gardening without a splint, playing an instrument again, or simply opening a jar without bracing for it, a consultation is the place to talk through nonsurgical care, joint replacement, and everything in between.
Frequently Asked Questions
Does Thumb Arthritis Go Away on Its Own?
No. Cartilage that has already worn away does not grow back, so thumb arthritis does not resolve on its own. Splinting, activity changes, hand therapy, and injections can quiet symptoms considerably, which is why many people manage the condition for years without surgery.
How Do I Know If My Thumb Arthritis Needs Surgery?
Surgery enters the conversation when splinting, injections, and hand therapy no longer control daily pain, or when weakness limits routine tasks such as opening jars, typing, or gripping a steering wheel. Imaging showing advanced joint damage is part of the picture, but symptoms and daily function usually drive the decision.
Is Total Thumb Arthroplasty an Outpatient Procedure?
Yes. Thumb joint replacement is typically performed on an outpatient basis through a small incision, so patients go home the same day.
How Long Does Recovery Take After Thumb Joint Replacement?
Guided hand therapy usually begins within the first couple of weeks after surgery, with light daily activities resuming early and strength building across three to six months. The exact pace depends on bone quality, the stage of arthritis at the time of surgery, and how the hand responds to therapy.
