November 20, 2025 updated by: Wake Forest University Health Sciences

Functional, Clinical, and Performance Outcomes Following Pelvic and Acetabular Fracture: A Prospective Observational Study

The purpose of this study is to understand the trajectory of function and self-reported outcomes of patients following pelvic and acetabular, treated both operatively and nonoperatively.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

The goal of the study study is to prospectively capture data from patients following pelvic and acetabular fractures, treated both operatively and nonoperatively, in order to understand the trajectory of functional and self-reported outcomes as well as to answer critical questions about treatment. Performance assessment data and patient-reported outcome measures utilizing the NIH PROMIS tool will be collected and analyzed for patients following pelvic or acetabular fracture, regardless of treatment.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

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
Return to work/activities
Time Frame: 0-24 months following injury
Average time to return to work and activities
0-24 months following injury

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
Change in patient-reported outcomes measurement information system (PROMIS 29) scores
Time Frame: baseline, 3, 6, 12 and 24 months
The PROMIS-29 assesses seven health domains: physical function, anxiety, depression, fatigue, sleep disturbance, pain interference, and ability to participate in social roles and activities. Each of the seven domains has four questions which are scored on a five-point Likert scale. The PROMIS-29 scales will be scored using a T-score metric method available at the Assessment Center website (http://assessmentcenter.net). A score of 50 points represents the population average for each scale, and 10 points represent one standard deviation. Higher scores mean more of the specific scale's construct, which may indicate a desirable or an undesirable outcome.
baseline, 3, 6, 12 and 24 months
Fracture Healing
Time Frame: 0-24 months following injury
Union rates as measured clinically and radiographically. Xrays will be collected from the electronic medical record.
0-24 months following injury
Complications
Time Frame: 0-24 months following injury
Rates of readmission, reoperations and complications
0-24 months following injury
Performance Measure- 10 meter walk test
Time Frame: 3, 6, 12 and 24 months
Participants complete a modified 10 meter walk test which involves the subject starting from a standing position, walking 5 meters at a comfortable pace, turning around, and then walking back 5 meters to the original starting point. The test is repeated twice for each subject.
3, 6, 12 and 24 months
Performance Measure- Five Time Sit to Stand Test
Time Frame: 3, 6, 12 and 24 months
Participants begin from a seated position and are directed to come to a full standing position without push off assistance from upper extremities and then return to a seated position without upper extremity assist.
3, 6, 12 and 24 months
Performance Measure- Timed Up and Go Test
Time Frame: 3, 6, 12 and 24 months
Participants begin in a seated position. They are directed to stand and walk 3 meters to a cone on the floor. They are to round the cone in a continuous motion, walk back to the chair, turn again and be seated. The entire test is performed at a comfortable and safe speed for the patient.
3, 6, 12 and 24 months

Primary Completion (Estimated)

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.
