Radial Head Arthroplasty A Clinical and Radiological Comparison of Monopolar and Bipolar Radial Head Arthroplasty (RHA)

December 17, 2017 updated by: Sundsvall Hospital

Radial Head Arthroplasty: A Clinical and Radiological Comparison of Monopolar and Bipolar Radial Head Arthroplasty

Fractures of the radial head are among the most common fractures in the elbow and represent one-third of all elbow fractures.This retrospective cohort study was performed between 2004 and 2014 at Sundsvall and Umeå University hospital, Sweden. All patients who were operated on between 2004 and 2014 with a radial head arthroplasty for an acute or sequelae due to a caput radii fracture.The aim of this study is to evaluate clinical or radiological differences between patients treated with a unipolar or bipolar radial head arthroplasty.

Study Overview

Status

Status

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

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.

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.
Observational

Enrollment (Actual)

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.
27

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

All patients treated with a radial head arthroplasty are included in the study. All patients were asked to participate in the follow-up during 2017.

Description

Inclusion Criteria:

  • All patients treated with a radial head arthroplasty during the study period.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Bipolar radial head arthroplasty
Patients treated with bipolar head arthroplasty due to radial head fracture
Procedure: Type of radial head arthroplasty
Patiens are either treated with a unipolar or a bipolar radial head arthroplasty. At Sundsvall hospital all patients were treated with a unipolar and at Umeå university hospital all patients were treated with a bipolar arthroplasty.
Unipolar radial head arthroplasty
Patients treated with unipolar head arthroplasty due to radial head fracture
Procedure: Type of radial head arthroplasty
Patiens are either treated with a unipolar or a bipolar radial head arthroplasty. At Sundsvall hospital all patients were treated with a unipolar and at Umeå university hospital all patients were treated with a bipolar arthroplasty.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
QuickDASH
Time Frame: 2-16 years postoperatively
Patients reported outcome measure. An abbreviated version of the Disabilities the Arm, Shoulder and Hand (DASH) questionnaire. Higher score indicate a greater level of disability, lower scores indicate a lower level of disability. The score ranges from 0 (no disability) to 100 (most severe disability).
2-16 years postoperatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain
Time Frame: 2-16 years postoperatively
Visual analogue scale. Range 0-10. Higher value indicate more intensive pain.
2-16 years postoperatively
Range of motion
Time Frame: 2-16 years postoperatively
Rang of elbow motion. Measured in grades. Supination, pronation, extension and flexion were measured.
2-16 years postoperatively
Reoperation
Time Frame: 2-16 years postoperatively
Number of patients needing revision surgery
2-16 years postoperatively
Radiographic evaluation
Time Frame: 2-16 years postoperatively
Radiographic evaluation of the prosthesis. The presence of radiolucent lines, loosening of the prosthesis.
2-16 years postoperatively

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
