Thumb Arthritis Treatment in Raleigh, NC
Pain at the base of your thumb when gripping, pinching, opening jars, or turning keys? Thumb basal joint arthritis is one of the most common causes of hand pain — and very treatable, often without surgery.
What Is Thumb Arthritis?
Thumb carpometacarpal (CMC) arthritis — also called basal joint arthritis or thumb saddle joint arthritis — occurs when the cartilage in the joint at the base of the thumb wears away. This joint handles enormous stress during everyday pinch and grip activities. As cartilage deteriorates, bones rub together causing pain, swelling, and weakness.
It is significantly more common in women, and hormone-related ligament laxity is thought to contribute. The condition typically develops after age 40–50 and progresses gradually over years. Most patients find that symptoms come and go early on, before becoming more constant.
ⓘ Thumb CMC arthritis affects the joint where the thumb meets the wrist — not the knuckle. It is different from trigger thumb or finger arthritis.
Risk Factors
Several factors are associated with a higher likelihood of developing this condition.
Female Sex
3× more common; hormone-related ligament laxity
Age 40+
Prevalence increases sharply after 50
Family History
Strong genetic component to joint laxity
Pinch-Heavy Work
Seamstresses, musicians, dentists, painters
Prior Injury
Old thumb fracture or ligament tear
Obesity
Increases joint loading forces
Stages of Thumb Arthritis
Joint space preserved. Ligament laxity present. Pain with specific activities only.
Joint space narrows. Osteophytes form. Bony prominence visible at thumb base.
Severe joint destruction. Adjacent joints involved. Constant aching at rest.
Diagnosis
Thumb arthritis is diagnosed with a physical examination and X-rays. Dr. Chambers performs the grind test — axial pressure combined with rotation of the thumb — which reproduces the characteristic pain of CMC arthritis. X-rays confirm the degree of joint space loss and the presence of osteophytes (bone spurs).
- ✓Grind test (axial load and rotation of thumb)
- ✓Assessment of pinch and grip strength
- ✓X-rays of the thumb in AP, lateral, and stress views
- ✓Staging (Eaton Classification I–IV)
- ✓Evaluation of adjacent joints (scaphotrapezial)

Treatment Options
Dr. Chambers will recommend the best approach based on your severity, goals, and lifestyle. Most conditions are first treated non-surgically.
Thumb Spica Splint
A custom or prefabricated splint immobilizes the CMC joint, reducing stress and inflammation. Worn during painful activities or at night. Very effective for early to moderate arthritis and during acute flares.
Corticosteroid Injection
A cortisone injection directly into the CMC joint provides significant short-term pain relief — often lasting 3–6 months. Very helpful for acute flares, before events, and as a diagnostic test. PRP injection is an emerging alternative.
LRTI (Ligament Reconstruction & Tendon Interposition)
The arthritic trapezium bone is removed and a portion of the FCR tendon reconstructs the joint. The gold standard for thumb CMC arthritis — excellent, lasting pain relief with preserved thumb length and strength.
What to Expect During Recovery
Thumb Spica Cast
Thumb immobilized in a cast. Keep elevated to reduce swelling. Mild pain managed with medication.
Removable Splint
Cast replaced with removable splint. Gentle range-of-motion exercises begin under therapist guidance.
Hand Therapy
Active rehabilitation begins. Grip and pinch strengthening. Most daily activities resumable.
Full Recovery
Full grip and pinch strength typically restored. Final function often better than pre-surgery because pain no longer limits use.
Frequently Asked Questions
Thumb CMC arthritis affects the joint at the base of the thumb where it meets the wrist — causing pain with pinch and grip. Trigger thumb involves the flexor tendon locking or catching as you bend the thumb — a completely different condition treated differently. Dr. Chambers often sees both in the same patient.
Most patients actually gain strength after recovering from LRTI surgery, because pain no longer limits their ability to grip and pinch. Studies show grip and pinch strength return to near-normal by 6 months and patients describe the thumb as feeling "like new."
Relief typically lasts 3–6 months, though this varies. Injections can be repeated (limit 3 per year) but when they stop providing adequate or lasting relief, LRTI surgery is a very well-proven option with 95%+ patient satisfaction.
For patients with advanced CMC arthritis failing non-surgical treatment, LRTI surgery has one of the highest satisfaction rates of any orthopedic procedure — over 95% in long-term studies. Pain relief is typically dramatic and permanent. Most patients wonder why they waited so long.
Many patients manage very well for years with splints and periodic injections. Surgery is not required until symptoms significantly affect quality of life despite conservative measures. Dr. Chambers will never push surgery — the decision is always yours.
