Treatment of Olecranon Fractures in the Elderly (CROFT2)

March 21, 2025 updated by: Frede Frihagen, Oslo University Hospital

Operative or Non-Operative Treatment of Displaced Fractures of the Elderly - a Nordic Multicenter Randomized Trial

Operative treatment, with tension band wiring or plate fixation, will be compared with non-operative treatment of displaced olecranon fractures (Mayo classification 2A and 2B) in patients 75 years or older.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Displaced olecranon fractures disrupt the extensor mechanism of the elbow and operative treatment is therefore usually recommended. Tension band wiring (TBW) and plate fixation (PF) are the most common surgical treatment options. Both methods are associated with high complication and reoperation rates, especially in elderly patients. Only one randomized controlled trial has compared operative and non-operative treatment of olecranon fractures in the elderly, but the study was stopped prematurely due to high complication rates in the group treated operatively and remained underpowered for important outcome measures.A few small patient series with non-operatively treated fractures also exist and suggest that it may be a valid alternative to operative treatment

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
76

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

75 years and older (Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Displaced olecranon fracture (Mayo 2A and 2B).

Exclusion Criteria:

  • Associated fractures in the coronoid process, radial head or distal humerus.
  • Open fracture, Gustilo-Andersen 2 or 3
  • Severe cardiopulmonary disease or other medical condition which contraindicates surgery.
  • Previous injury to or other condition in the elbow with serious functional impairment

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Operative
Patients will be operated according to Orthopedic Trauma Association (OTA) principles with either tension band wiring or plate fixation with an anatomical precontoured plate.
Procedure: Tension band wiring or plate fixation
Choice of operative treatment is TBW or PF with a precontoured anatomical plate. The treating surgeon decides if TBW or PF is chosen as operative treatment method. The surgeries are performed according to OTA principles by an experienced surgeon, a trauma fellow or a consultant as approved by the participating hospitals.
Experimental: Non-operative
Patients will be offered a plaster cast for 1-2 weeks
Procedure: Active non-operative treatment with optional plaster cast
Patients allocated to non-operative treatment are offered a back-slab in 60 degrees of flexion for pain-relief. The back-slab is removed 7-14 days following injury.
