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.

Detailed Description

Potential of surgical stabilization of rib fractures (SSRF) to improve clinical outcomes in patients has been demonstrated with increasing interest of surgeons in this procedure and indications for SSRF expanding. Some reports found signals for hardware removal after SSRF such as hardware failure, infections and persisting pain. There is currently lack of studies collecting systematically long-term outcomes after SSRF hardware removal. For that reason, this project presents the retrospective case series of patients with removal of osteosynthetic material after rib stabilisation treated at Department of Thoracic Surgery of the University Hospital Basel (USB). The recovery of these patients will be reviewed and a prospective evaluation of long-term outcomes will be done. The aim is to provide an insight and implications for treatment strategies of future patients. Most of the collected patient data are retrospective data. One prospective follow-up visit inclusive a health survey per patient will be performed.

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

  • Patient will be included if a signed USB general research consent approval is available but patient cannot be reached or disagreed to come to the follow-up visit
  • Patient who died will be included if a signed USB general research consent approval is available

Exclusion Criteria:

  • Patients who received re-osteosynthesis on the same day as hardware removal
  • Patients received conservative therapy or surgery with absorbable plates

  • On hardware implantation:

    • Penetrating chest trauma
    • Only random findings of rib fractures
    • Solitary sternocostal joint fracture and/or solitary sternum fracture and/or solitary fractures of rib connecting parts and/or solitary thoracic spine/vertebra fracture
    • In-hospital: Patient suffered only iatrogenic rib facture during a surgery, cardiac surgery
    • Rib fractures/non-unions caused by malignancy or rib surgery due to malignancy, radiation therapy, COPD, coughing
  • Inability to follow procedures or insufficient knowledge of language (German/French) or impaired communication or inability to give consent

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
Health survey of long-term outcome after hardware removal (Quality of life assessment)
Time Frame: One time assessment at baseline (prospective Follow up-visit)
The questions are formulated as an adapted question set of the EQ-5D-5L Dimension (EQ-5D-5L) questionnaire followed by additional study specific questions. A numerical rating scale (NRS) will be used for evaluation from 0 - 10. In addition, the patient will be asked to rate the condition now compared to before hardware removal in four categories (less good, no change, slightly better, much better). The analysis of the project data will be done descriptive.
One time assessment at baseline (prospective Follow up-visit)

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.
