Study summary

This study compares two types of artificial implants used to replace a broken part of the elbow (the radial head) when the bone is too damaged to repair. One implant (press-fit) is designed to grip the bone tightly so bone grows into it and holds it in place. The other implant (loose-fit) has a smooth stem that sits loosely in the bone and is meant to move slightly. Both implants are already approved and widely used; doctors do not yet know if one works better than the other. People taking part are placed by chance into one of the two implant groups. The study will follow them for at least 2 years to see how far they can bend and straighten the elbow, how much pain they have, how well the elbow works in daily life, whether the implant stays in good position on X-rays, and whether any further surgery is needed.

Exclusion criteria

Exclusion Criteria:

  1. Diagnosed with any significant comorbidities that could interfere with rehabilitation or study participation, including but not limited to:

    • Severe osteoarthritis affecting elbow function
    • Rheumatoid arthritis or other disorders affecting musculoskeletal function
    • Full-thickness cartilage lesion in the elbow joint
    • Neurological or vascular complications
    • Neuromuscular disorders affecting movement or coordination
    • Neurocognitive conditions impacting study participation

    • Active alcohol or substance dependence
    • Nicotine/tobacco use
    • Chronic use
    • Recent chemotherapy
  5. Any condition that, in the opinion of the principal investigator, would make participation in the study unsafe or not in the patient's best interest.
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Elbow Flexion-Extension Arc of Motion

    Total arc of elbow flexion-extension in degrees (maximum flexion minus loss of extension), measured with a goniometer. The primary comparison between groups is at 24 months postoperatively. Measurements at earlier time points are reported to describe recovery over time.

    Time frame: Baseline, 3 months, 6 months, 12 months, and 24 months postoperatively

Secondary outcomes

  1. Forearm Rotation Arc of Motion

    Total arc of forearm rotation in degrees (maximum pronation plus maximum supination), measured with a goniometer.

    Time frame: Baseline, 3, 6, 12, and 24 months postoperatively

  2. Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) Score

    The QuickDASH is an 11-item patient-reported questionnaire assessing upper extremity function and symptoms. Scores range from 0 to 100, and higher scores indicate greater disability (worse outcome).

    Time frame: Baseline (preoperative), 3, 6, 12, and 24 months postoperatively

  3. Mayo Elbow Performance Score (MEPS)

    The MEPS assesses elbow pain, range of motion, stability, and ability to perform daily activities. Scores range from 0 to 100, and higher scores indicate better elbow function (better outcome).

    Time frame: Baseline (preoperative), 3, 6, 12, and 24 months postoperatively

  4. Visual Analog Scale (VAS) for Pain

    Participants mark their pain intensity on a continuous line scored from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate worse pain.

    Time frame: Baseline, 3, 6, 12, and 24 months postoperatively

  5. Number of Participants Receiving Corticosteroid Injections

    Number of participants who receive one or more corticosteroid injections to the operative elbow after radial head arthroplasty.

    Time frame: Through 24 months postoperatively

  6. Number of Participants Requiring Reoperation

    Number of participants who undergo any secondary surgical procedure on the operative elbow after the index radial head arthroplasty, including stiffness release and implant removal.

    Time frame: Through 24 months postoperatively

  7. Number of Participants With Radiographic Implant Loosening

    Intramedullary stem loosening on standard elbow radiographs.

    Time frame: Through 24 months postoperatively

  8. Number of Participants With Radiographic Implant Subsidence

    Implant subsidence on standard elbow radiographs compared with immediate postoperative radiographs.

    Time frame: Through 24 months postoperatively

  9. Number of Participants With Radial Neck Resorption

    Radial neck bone resorption (stress shielding) on standard elbow radiographs.

    Time frame: Through 24 months postoperatively

  10. Number of Participants With Heterotopic Ossification

    Heterotopic ossification on standard elbow radiographs.

    Time frame: Through 24 months postoperatively

  11. Number of Participants With Surgical or Implant-Related Complications

    Number of participants with one or more complications related to the surgery or implant, including implant loosening, infection, stiffness, nerve injury, instability, or implant failure.

    Time frame: Through 24 months postoperatively

  12. Grip Strength

    Maximum grip strength of the operative hand in kilograms, measured with a hand-held dynamometer.

    Time frame: 3, 6, 12, and 24 months postoperatively

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2026 (actual). Primary completion is estimated for Sep 2031, 68 months after the start.

Of 15 interventional studies with no phase under Elbow Fractures, half reached primary completion within 22 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 36. This study's planned 68 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
