Prices vary by hospital, by the surgeon and by implant choice. Hand therapy is a genuine part of the outcome and worth budgeting for.

The problem

The right operation, the right hand, and a proper therapist.

Thumb-base surgery is where implant marketing quietly overreaches - trapeziectomy skipped, therapy underdone, revision risk minimised. We fix all three before you consent.

  • Could an injection buy you another year?

    For milder disease and lower-demand hands, an ultrasound-guided steroid injection often earns more time. We say so before recommending surgery.

  • Trapeziectomy is still excellent

    Decades of durable outcomes, low complications, cheap. We only recommend an implant when the case genuinely benefits.

  • The therapist matters as much as the surgeon

    A CHT-accredited hand therapist from week two is not optional. The best implant will underperform without proper rehab.

When it helps

When thumb base surgery is the right step.

The situations we see most, plus the one red flag that means a same-day A&E visit rather than a routine hand clinic.

  • Painful thumb base arthritis

    Ache at the base of the thumb, worse with pinching, opening jars or turning keys. The classic first symptom.

  • Failed conservative treatment

    You have tried splints, hand therapy and one or two steroid injections - and are still limited.

  • Stage III–IV CMC osteoarthritis

    Eaton–Littler stage III or IV on X-ray, with joint-space loss, osteophytes and often subluxation.

  • Grip and pinch weakness

    Difficulty holding a mug, buttoning a shirt, using scissors - objective weakness on pinch testing.

  • Deformity of the thumb column

    A collapsed thumb column (adduction contracture with MCP hyperextension) can still be corrected with implant or trapeziectomy.

  • Dominant-hand impact

    A working right hand in a right-handed writer, sewer or surgeon - where the functional loss is disproportionate to X-ray grade.

  • Post-traumatic arthritis

    Old fracture or dislocation at the CMC joint that has progressed to symptomatic arthritis.

  • Red flag: hot swollen joint with fever

    A hot, swollen, red thumb base with fever is septic arthritis, not osteoarthritis - same-day A&E, not a clinic booking.

Procedure options

Implant, trapeziectomy or something in between.

Every option, honestly compared - including the non-surgical treatments that might buy you time.

  • Dual-mobility total CMC replacement

    Modern total-joint prostheses (Touch, Ivory, Maia, Isis) mimic the natural saddle joint. Fast recovery, strong pinch - but longer-term data is still maturing.

  • Pyrocarbon interposition implant

    A pyrocarbon spacer sits between the trapezium and metacarpal. Good pain relief; occasional subluxation.

  • Resurfacing arthroplasty

    Only the joint surfaces are replaced. Preserves bone stock; suited to earlier-stage disease.

  • Trapeziectomy alone

    Simply removing the trapezium. Excellent pain relief, cheap and durable - the UK NHS default. Longer rehab and slightly weaker pinch.

  • Trapeziectomy with ligament reconstruction and tendon interposition (LRTI)

    Adds a tendon graft to keep the thumb column stable. The most studied comparator for implants.

  • Suture-button suspensionplasty

    A newer alternative to LRTI using a mini-tightrope button. Faster return to activity; still gaining evidence.

  • Fusion (CMC arthrodesis)

    For heavy-manual workers who need a strong, painless thumb and can accept losing rotational movement.

  • Non-surgical alternatives

    Splints, hand therapy, oral anti-inflammatories and steroid or hyaluronic acid injections - often buys years for milder disease.

Safety and recovery

What to expect afterwards - honestly.

Thumb-base surgery is well established. The variables are implant choice, therapy quality, and how patient you are during rehab.

  • Regional block or general anaesthetic

    Most cases are done under a brachial plexus block with sedation. GA is offered when preferred. Discussed with the anaesthetist at pre-assessment.

  • Bleeding, infection, wound healing

    Superficial infection under 2 percent; deep infection under 1 percent. Wound review at two weeks with the hand therapist.

  • Nerve irritation (superficial radial branch)

    A branch of the radial nerve crosses the surgical field. Numbness or tingling on the back of the thumb can settle over months.

  • Implant dislocation or loosening

    The biggest implant-specific risk. Rates vary by prosthesis and surgeon. Modern dual-mobility designs report 90–95 percent survivorship at 5 years.

  • Stiffness and pillar pain

    Some scar tenderness and stiffness is normal for 3–6 months and responds to hand therapy.

  • Grip and pinch outcomes

    Pain relief is reliable in over 90 percent. Pinch strength typically peaks around 6 months and can exceed pre-op levels.

  • Return to work and activity

    Desk work: 2–3 weeks. Manual work: 8–12 weeks. Full unrestricted activity by 3–4 months.

  • When trapeziectomy still wins

    For lower-demand hands, previous failed implant, small trapezium or specific anatomy - the classic operation is durable, cheap and low-risk.

  • Red flags after surgery

    Fever, spreading redness, sudden loss of movement or worsening pain need the same-day team or A&E.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever technique was used - implant, trapeziectomy or suspensionplasty - the note keeps to the same shape.

Frequently asked

Everything we get asked about thumb base surgery.

Quick answers on implants, trapeziectomy, therapy, cost and recovery.

  • Is thumb base joint replacement better than trapeziectomy?

    Modern dual-mobility implants offer faster pain relief and stronger pinch than trapeziectomy in the first year, but trapeziectomy has 40 years of durable, cheap, low-risk outcomes behind it. The right choice depends on hand demand, anatomy, age and how much you value early return over long-term evidence.

  • What is thumb base joint replacement?

    It replaces the arthritic joint at the base of the thumb (the trapeziometacarpal or CMC joint) with a small artificial implant - usually a cup in the trapezium and a stem in the metacarpal. It is a keyhole-sized open procedure, done as a day-case in under 90 minutes.

  • How long do modern implants last?

    Dual-mobility total CMC prostheses report 90–95 percent survivorship at 5 years and around 85 percent at 10 years in specialist series. Ten- and fifteen-year data are still maturing. Trapeziectomy has no implant to fail.

  • When can I use my thumb again?

    Splint on for 4–6 weeks, hand therapy from week 2. Light desk work in 2–3 weeks, driving around week 4, manual work by 8–12 weeks. Peak grip and pinch strength by 6 months.

  • How much does thumb base joint replacement cost in the UK privately?

    Roughly £9,500–£14,000 for a standard implant, £11,000–£16,500 for a dual-mobility total replacement, and £6,500–£10,000 for trapeziectomy with LRTI. Hand therapy usually adds £450–£850.

  • Can I have both thumbs done at once?

    We do not recommend it. You will need one working thumb to feed yourself, wash and dress. We stage surgery about 3–6 months apart, once the first side has settled.
