Hip Socket Erosion Study

Netherlands134 participantsStarted 2024-06-19

Plain-language summary

The aim of this exploratory retrospective study is to gain a better understanding about the occurrence of acetabular erosion in patients after after hip hemiarthroplasty. The main objectives are i) to summarise a selection of basic patient characteristics of all patients of ≤ 75 years of age with a femoral neck fracture who have received either HA or THA, ii) to explore the proportion of patients after HA who developed acetabular erosion in the first years post-surgery and iii) to explore the proportion of patients after HA for whom acetabular erosion was the main reason for conversion surgery from HA to THA. A secondary objective is to assess the observer reliability of, and explore the association between, the Baker classification grading and Köhler line measurements. All participants approached for participation in the main phase of the study will be asked to give their written informed consent to use their patient data. Patients who are willing to participate will also be asked to complete a short paper survey to collect data that is not available from their health records.

Inclusion Criteria: * having had a displaced femoral neck fracture that was subsequently treated with hemiarthroplasty * aged \< 75 years at the time of surgery * have at least two post-operative radiographs (with at least six weeks between them) available for acetabular erosion measurements. Exclusion Criteria: * patients diagnosed with rheumatoid arthritis, osteoporosis, hip dysplasia or a previous hip fracture of the ipsilateral hip.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
