Thumb-base osteoarthritis — its cause, symptoms and diagnosis — is described in a dedicated page. This page deals with the point at which surgery becomes an option, and the question that arises then: remove the worn bone, or replace the joint? It sets out the techniques, their strengths, their limits, and the logic behind the choice — without taking sides, because there is no single answer.
What surgery aims to correct
At the base of the thumb, a small square bone, the trapezium, forms a saddle-shaped joint with the first metacarpal, giving the thumb its remarkable mobility. With osteoarthritis, the cartilage of this joint wears away: the bones rub against each other, causing pain, a loss of pinch strength and, eventually, deformity. Surgery is considered only after non-surgical treatments have failed (splint, activity changes, injections), and its goal is always the same: to eliminate the painful rubbing while preserving as much thumb function as possible.
Two opposing approaches: remove, or replace
Faced with this worn joint, the two main techniques respond with opposite philosophies — and understanding this contrast is the key to everything else.
Remove the bone
Trapeziectomy removes the worn trapezium. By removing the bone, the rubbing is eliminated at its source. The space left behind fills in naturally, and the thumb is often stabilized by an additional procedure (a strip of tendon, known as ligament reconstruction, sometimes with an interposition).
Replace it
The implant replaces the worn joint — a small artificial joint, often with a cup and stem, that restores the thumb's range of motion.
One takes away, the other substitutes: from this difference flow their respective advantages and limits.
The third option
However, a 3rd technique is particularly interesting: performing the trapeziectomy and restoring the thumb's range of motion with an artificial intermetacarpal ligament reconstruction, without interposition.

Trapeziectomy: the proven reference technique
It is the long-established technique, the one against which all others are measured. Its strengths are firmly established:
Reliable, lasting pain relief, demonstrated over many years — this is its great strength.
High reliability and few serious complications, with no implanted hardware that could wear out.
A proven and cost-effective solution, with predictable results.
Its main trade-off: a fairly long recovery — strength and comfort build gradually over several months — and a slight shortening of the thumb that can somewhat affect pinch strength. For many patients, the long-term reliability more than makes up for this slowness.
The implant: fast recovery, at the cost of the implant
Implant surgery, more recent and constantly improving, addresses trapeziectomy's main limitation — its slowness — with a different approach:
A faster recovery and an earlier return of strength and mobility, with the thumb's length preserved.
Early functional gains, often appreciated by active patients.
Its limits stem from its very nature: like any implant, it carries risks specific to the device — wear, loosening, dislocation — and a limited lifespan that may require revision. Recent implants have reduced these pitfalls, but the very long-term track record is still shorter than for trapeziectomy. This is a decisive factor, especially in young, active patients.
The key point: neither is superior overall
This is the most important message on this page, and the one where honesty must come before any preference.
What the research really says
Both techniques relieve pain effectively and improve function. Comparative studies show neither to be superior overall: the implant gives earlier functional results and a faster recovery, while trapeziectomy offers very long-term reliability and fewer implant-related complications.
The right choice is therefore multifactorial and unique to each patient: age, whether it is the dominant hand, heavy manual work, strength demands, an acceptable recovery time, and personal preferences. There is no single answer, but an answer tailored to each person.
This is why a surgeon skilled in all three techniques is best placed to advise: with no reason to favor one over another, they can recommend the one that truly fits.

Frequently asked questions
Only when non-surgical treatments — a splint, adapting how you use the hand, injections — are no longer enough to control the pain and discomfort. Surgery is never an emergency: it is a decision made when quality of life is lastingly affected. The timing is discussed case by case.
Neither is superior overall, and that is the key point. Both relieve pain effectively. Trapeziectomy is very reliable in the long term but recovers slowly; the implant recovers faster but carries the risks and limited lifespan of an implant. The right choice depends on your profile. A trapeziectomy combined with a prosthetic intermetacarpal ligament reconstruction remains an excellent choice that combines the advantages of both techniques.
It is the removal of the small worn bone at the base of the thumb, the trapezium. Taking it out eliminates the painful rubbing. The thumb is often stabilized with a strip of tendon. It is the reference technique, very reliable for pain, at the cost of a recovery lasting several months.
It is the replacement of the worn joint with a small joint implant that restores the thumb's movement and preserves its length. It allows a faster recovery and good early strength. In return, like any implant, it can wear or loosen over time, and so may require another operation.
Not necessarily. Like any artificial joint, it has a lifespan and may, in time, require revision. Recent models have improved longevity, but the very long-term track record is shorter than for trapeziectomy. This is an important consideration, especially in young, active patients.
It differs by technique: recovery is faster after an implant, more gradual after a trapeziectomy, where comfort and strength build over several months. The exact timelines, based on your activity, will be detailed during your consultation.
The goal is to eliminate the pain and restore a hand that works for everyday tasks. Pinch strength improves but may stay slightly below that of a healthy thumb, a little more so after trapeziectomy because of the slight shortening. Both techniques give good functional results.
A hand surgeon who ideally is skilled in all three techniques, which allows them to advise without bias. Dr Frédéric Teboul, a hand and peripheral nerve surgeon and member of the Académie Nationale de Chirurgie, can assess which is best suited to your situation.
