Thumb Base Arthritis Treatment in Manchester
Pain at the base of the thumb can make opening jars, turning keys, gripping a phone and pinching difficult. A focused hand assessment can confirm whether the carpometacarpal joint is the source and build a plan around pain relief, strength and daily function.

Specialist hand & wrist assessment
What is affected?
The carpometacarpal joint where the thumb metacarpal meets the trapezium.
Common clue
Pain with pinching, twisting a key, opening a lid or prolonged thumb use.
First treatments
Activity changes, hand therapy, a supportive splint, pain relief and selected injection.
When surgery?
When pain and loss of function remain significant despite suitable nonsurgical care.
Understanding the condition
What is thumb base arthritis?
Thumb base arthritis is wear of the cartilage in the thumb carpometacarpal joint. This joint allows the thumb to swivel, oppose and generate pinch, so even modest arthritis can affect everyday tasks.
Symptoms and X-ray changes do not always match perfectly. Treatment should be guided by pain, strength, stability and the activities the patient needs to perform.
Clear diagnosis before treatmentSimilar symptoms can arise from the neck, elbow, wrist, tendons or joints. The examination is designed to locate the true source.
What patients may notice
Symptoms worth checking early.
Symptoms vary with the condition, joint and duration. Persistent pain, stiffness, deformity, a growing lump or loss of function deserves specialist assessment.
Difficulty opening jars
Twisting and forceful pinch often reproduce symptoms.
Weak pinch or grip
Keys, buttons, clips and containers become harder to manage.
Swelling or a bony prominence
The joint may feel tender, enlarged or unstable.
Grinding sensation
Movement can cause crepitus or a gritty feeling.
Night or post-activity pain
Symptoms may continue after prolonged use or wake some patients.
Why it happens
Why thumb base arthritis develops
A useful consultation connects the symptom pattern to the joint or tissue involved and the underlying cause—not just the label.
Cartilage wear
The smooth joint surface gradually thins and becomes irregular.
Joint laxity
A naturally loose or unstable joint may experience higher stresses.
Previous injury
Fracture or ligament injury can accelerate joint wear.
Age and loading
Risk rises with age and repeated high-force pinch or grip.
Focused diagnosis
Find the tissue, the joint and the severity.
Assessment checks whether pain truly comes from the CMC joint or from nearby tendons, the wrist, carpal tunnel or another thumb joint.
Bring to your appointmentPrevious X-rays, scans, reports, medication details and information about work or activities that trigger symptoms.
Symptom and activity review
Tasks that reproduce pain and the impact on work or daily life are documented.
Thumb examination
Tenderness, motion, stability, pinch and grind are assessed.
X-rays
Joint-space narrowing, bone spurs, alignment and nearby arthritis are reviewed.
Selective injection
In some cases an injection can provide treatment and help confirm the pain source.
Treatment choices
Start with the option that fits the diagnosis.
Surgery is not automatic. Treatment is matched to pain, joint or tissue damage, function, medical health and the patient’s goals.
Non-surgical care
Reduce irritation, protect function and review progress.
- Joint-protection changesAdapt pinch, jar opening, phone use and heavy gripping.
- Thumb supportA soft or rigid thumb CMC splint can reduce painful motion.
- Hand therapyExercises, pacing and equipment advice help preserve function.
- Medication or topical treatmentAppropriate pain relief may be used after medical review.
- Selected corticosteroid injectionInjection can reduce inflammation for a period in suitable patients.
Surgical pathway
Reduce arthritic contact while preserving a stable, useful thumb.
- Trapeziectomy-based surgeryThe arthritic trapezium is removed with a chosen stabilisation technique.
- Suspension or ligament reconstructionA tendon or suture construct may support the thumb metacarpal.
- Joint fusion in selected casesFusion may suit particular patients requiring stability and power.
- Address neighbouring jointsAssociated STT or thumb MCP problems may need treatment at the same time.
Surgery when appropriate
Thumb CMC arthritis surgery
Surgery is considered when pain and disability remain limiting after a suitable trial of nonsurgical care. The exact technique depends on joint stage, neighbouring joints, work demands and surgeon preference.
- Confirm the thumb CMC joint is the main pain source
- Review nonsurgical treatment and functional goals
- Choose the procedure that matches the joint and patient
- Protect the thumb in a cast or splint while tissues heal
- Progress hand therapy, pinch and grip gradually
Realistic expectationsPain relief is usually gradual rather than immediate. Strength, swelling and confidence can continue improving for several months, and no operation can make an arthritic thumb identical to a normal joint.
Specialist pathwayDiagnosis → Procedure → Therapy → Recovery
Recovery pathway
Healing is staged—not rushed.
Timelines are guides only. The diagnosis, procedure, joint or tissue condition, job and medical health all influence recovery.
First 2 weeks
Elevation, wound care and finger movement while the thumb is protected.
2–6 weeks
A cast or splint is used according to the procedure.
6–12 weeks
Thumb motion and light function progress with hand therapy.
3–6 months
Pinch strength and heavier use return gradually; improvement may continue longer.

Thumb Base Arthritis FAQs.
General information only. Your diagnosis and treatment plan should be based on an individual medical assessment.
Is thumb arthritis the same as De Quervain’s?+
No. Thumb CMC arthritis affects a joint at the base of the thumb; De Quervain’s affects tendons on the thumb side of the wrist.
Does a bad X-ray mean I need surgery?+
Not by itself. Symptoms, function and response to nonsurgical care are more important than the X-ray alone.
Can a splint help?+
A well-fitted thumb support can reduce painful motion and make tasks easier, although it does not restore worn cartilage.
How long does surgery take to recover from?+
Light activities may return in weeks, but strength and comfort commonly improve over several months depending on the procedure.
Can I arrange thumb arthritis assessment in Manchester?+
Yes. Dr. Arshad offers specialist hand assessment in Manchester, UK and during UK clinical availability.
