Shoulder resurfacing - a bone-preserving alternative to a stemmed replacement.

A metal cap prosthesis fitted onto the trimmed humeral head - Copeland, Global CAP, Epoca RH - by a consultant upper-limb surgeon who still resurfaces regularly. For younger, post-traumatic and AVN patients who want to preserve bone stock for a straightforward revision later.

Indicative pricing

What private shoulder resurfacing costs in the UK.

Indicative ranges across our partner upper-limb units, physiotherapy quoted alongside.

In short

£12,000–£18,000, home in one or two nights.

Procedure Indicative range
Humeral head resurfacing (cap prosthesis) £12,000–£18,000
Resurfacing hemiarthroplasty with glenoid reaming £13,500–£19,500
Partial (surface) resurfacing plug £9,500–£14,000
Conversion of failed resurfacing to stemmed TSA £22,000–£32,000
Conversion to reverse shoulder arthroplasty £24,000–£34,000
Post-op physiotherapy package (12 sessions) £720–£1,320
Orthopaedic consultation £250–£350

Prices vary by hospital, by surgeon and by implant. Conversion to a stemmed or reverse arthroplasty later in life is priced at the top of the range because it is a longer, more complex operation - even though the resurfacing preserves the bone stock that makes it possible.

The problem

The right operation for your decade, not the default one.

Shoulder arthroplasty is where general orthopaedics quietly defaults to whatever a unit does most. Most units default to a stemmed or reverse replacement. Resurfacing is a real option for the right patient - and worth a conversation before you consent.

  • Age matters more than pain

    A 48-year-old with painful OA has a different 30-year horizon than a 72-year-old. A cap preserves the humeral canal for a straightforward revision when - not if - the time comes.

  • The glenoid decides the case

    A preserved glenoid supports a hemiarthroplasty cap. A worn glenoid usually points to a stemmed TSA. We look at the CT together before recommending an implant.

  • Rule out the cuff before you cap

    A cuff-deficient shoulder needs a reverse arthroplasty, not a resurfacing cap. MRI first, cap second - never the other way round.

When it helps

When resurfacing is the right step.

The patient profiles where humeral head resurfacing still earns its place - and the one red flag that means a reverse arthroplasty instead.

  • Younger, active patient with primary osteoarthritis

    Patients in their 40s or 50s with painful glenohumeral OA who want to preserve bone stock for a probable revision later in life.

  • Post-traumatic arthritis

    Arthritis after a proximal humerus fracture where the anatomy is distorted but the humeral head is largely intact - resurfacing sidesteps a difficult stem insertion.

  • Avascular necrosis (early collapse)

    Ficat stage 3 AVN where the head has begun to collapse but the subchondral bone still supports a cap. Common in steroid users, sickle cell, divers, post-fracture.

  • Single-sided rheumatoid arthritis

    Well-controlled rheumatoid disease with preserved glenoid bone - a cap avoids the stem complications that RA bone often struggles with.

  • Failed non-arthroplasty surgery

    A stiff, arthritic shoulder after arthroscopic debridement, capsular release or biological resurfacing that has run out of runway.

  • Distorted proximal humeral anatomy

    A humerus where a stem cannot be safely centred - old malunion, retained hardware, or narrow canal - but the articular surface can still be capped.

  • Patient preference for bone preservation

    A well-informed patient who understands the trade-offs and prefers to keep the option of a straightforward conversion to a stemmed or reverse replacement later.

  • Red flag: cuff-deficient shoulder with pseudoparalysis

    A shoulder that cannot actively elevate because the cuff has failed is not a resurfacing case - it needs a reverse arthroplasty, not a cap.

Procedure options

The variants of resurfacing, and where each one fits.

Cap, partial plug, ream-and-run, cemented or press-fit - the choice hinges on bone quality, glenoid status and the surgeon’s honest assessment of what will last.

  • Humeral head resurfacing (Copeland-type cap)

    The classic operation. The head is reshaped, a metal cap (Copeland, Global CAP, Epoca RH, Aequalis Resurfacing Head) is fitted onto the trimmed bone. No canal instrumentation.

  • Resurfacing hemiarthroplasty

    Cap alone against the native glenoid. Works well where the glenoid cartilage is preserved; less durable where the glenoid is worn - glenoid pain is the classic failure mode.

  • Resurfacing with glenoid reaming (ream and run)

    Cap plus a spherical reaming of the glenoid to smooth an eccentric or worn surface. Avoids a plastic glenoid component while addressing bipolar disease.

  • Cap with cemented all-poly glenoid

    A total shoulder configuration using a resurfacing cap on the humeral side. Rare in current practice - most surgeons who commit to a glenoid component use a stem for lever arm.

  • Partial (surface) resurfacing plug

    A small cobalt-chrome plug for a focal chondral defect or contained AVN lesion in a young patient. Preserves nearly all the humeral head.

  • Uncemented press-fit cap

    Hydroxyapatite-coated undersurface allows biological fixation without cement. Preferred in most modern series where bone quality supports press-fit.

  • Cemented cap

    Used where the bone is soft, cystic or sclerotic - most rheumatoid and AVN cases, and revision from a failed hemiarthroplasty where cement is already in situ.

  • Custom / patient-specific cap

    Rarely, a bespoke cap is manufactured from a CT for markedly distorted anatomy - expensive, and only offered by a handful of UK centres.

Safety and recovery

What to expect afterwards - honestly.

Resurfacing is a well-established operation. The things worth planning for are the sling protocol, the graded physiotherapy, and the small chance the glenoid wears in a decade and asks for a stemmed conversion.

  • GA with interscalene block, in a proper theatre

    The block covers pain for 12–18 hours and lets physio start the next day. One or two nights in most cases; longer if pain or mobility are slow.

  • Glenoid wear is the classic failure mode

    A metal cap articulating with a native glenoid can wear the socket over five to ten years. Persistent, deep anterior pain after an initially good result is the tell - revision to TSA or reverse is usually the answer.

  • Oversizing the cap

    A cap that is too large or medialised overstuffs the joint, restricts motion and loads the cuff. Careful templating and intraoperative trials matter - this is where surgeon volume pays off.

  • Cuff failure after the operation

    A subscapularis takedown for the approach may fail to heal, especially in older patients or smokers. Repair protection with a sling for four to six weeks is non-negotiable.

  • Bleeding and haematoma

    A symptomatic haematoma needing drainage is under 2 percent. The block masks pain - swelling, tightness and warmth are the signs to call about, not pain alone.

  • Nerve injury

    Axillary nerve neurapraxia around the deltopectoral approach is rare but recognised. Numbness in the deltoid patch usually settles within weeks.

  • Infection

    Deep prosthetic joint infection is 0.5–1 percent. Cutibacterium acnes is the shoulder-specific organism - indolent, low-grade and easy to miss. Any persistent, unexplained pain after six months deserves investigation.

  • Fracture during cap seating

    A rare humeral head fracture during impaction, more likely in AVN or cystic bone. Recognised on the table and managed with cement, wires or conversion to a stem at the same sitting.

  • Revision is easier than after a stem

    The bone-preserving nature is the whole point - when the cap eventually fails, the surgeon still has an unviolated humeral canal for a straightforward stemmed or reverse arthroplasty.

  • Red flags after surgery

    Fever, spreading redness, calf pain, breathlessness, sudden loss of active elevation, or numbness that fails to settle after 24 hours need the same-day team or A&E.

Shoulder arthroplasty - including resurfacing - is usually covered where conservative treatment has failed. On the NHS, resurfacing is limited to a handful of specialist upper-limb centres.

Frequently asked

Everything we get asked about shoulder resurfacing.

Quick answers on candidacy, longevity, why the technique is used less, and what happens when a cap eventually fails.

  • What is shoulder resurfacing surgery?

    Shoulder resurfacing replaces only the worn articular surface of the humeral head with a metal cap prosthesis - the Copeland, Global CAP, Epoca RH and Aequalis Resurfacing Head are the best known. The humeral canal is not instrumented, so much more of the patient’s own bone is preserved than in a stemmed total shoulder replacement.

  • Why is resurfacing not offered as often as it used to be?

    Two reasons. First, glenoid wear against an uncovered metal cap became a recognised failure mode in the mid-2010s, especially where the glenoid was already worn. Second, modern short-stem and stemless arthroplasty designs offered similar bone preservation with easier soft-tissue balancing. Resurfacing remains a good option in the right hands and the right patient - younger, post-traumatic, AVN, and single-sided rheumatoid cases with a preserved glenoid.

  • Who is a good candidate for a humeral resurfacing cap?

    Typically a patient in their 40s or 50s with painful glenohumeral arthritis, a competent rotator cuff, preserved glenoid cartilage and reasonable humeral bone stock. Post-traumatic arthritis with distorted anatomy, early AVN and single-sided rheumatoid disease also do well. It is not suitable for cuff-deficient shoulders - those need a reverse arthroplasty.

  • How long does a shoulder resurfacing last?

    Published series from the Copeland group and others show around 85–90 percent survivorship at ten years in appropriately selected patients. Glenoid wear is the main reason for revision - most caps come out because of glenoid pain, not because the cap itself has loosened.

  • What happens if the resurfacing fails?

    The whole point of resurfacing is that the humeral canal has never been touched, so conversion to a stemmed total shoulder replacement or a reverse arthroplasty is technically much easier than revising a failed stemmed implant. Bone stock is largely preserved and the second operation behaves like a primary arthroplasty.

  • How much does private shoulder resurfacing cost in the UK, and can it be done on the NHS?

    On the NHS, resurfacing is available only in a handful of specialist upper-limb centres - most units default to stemmed or reverse arthroplasty. Referral to a resurfacing-focused surgeon usually needs to be requested by name.
