A Clinical Trial for the Surgical Treatment of Elderly Distal Radius Fractures


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

In the United States, over 300,000 individuals over age 65 suffer from distal radius fractures (DRFs) each year. Despite the frequency of this injury and over 200 years of experience treating DRFs, management of elderly DRFs is still controversial. Close reduction and casting is a nonsurgical technique that is frequently used, but osteoporotic fractures, common in the elderly, often collapse and displace. The three currently applied surgical techniques are close reduction and percutaneous pinning, external fixation with or without percutaneous pinning, and internal fixation with volar locking plating. Preliminary evidence indicates that locking plate fixation can permit elderly patients to move their hands and wrists much sooner in order to return to self-care activities more quickly. Although these outcomes are promising, there is no randomized controlled clinical trial to demonstrate that the more invasive, and perhaps more costly, plating technique is superior to the other simpler approaches.

The specific aim of this 18-center randomized controlled trial is to compare outcomes of these three surgical techniques in treating unstable DRFs in the elderly. The secondary aim is to follow a cohort of elderly patients who choose not to have surgery to evaluate outcomes following treatment by close reduction and casting alone. This clinical trial is the most ambitious study in hand surgery by assembling most of the leading centers in North America to collect evidence-based data to guide future treatment of this prevalent injury in the growing elderly population.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
