Hip Socket Erosion Study

Status Not yet recruiting

Clinical Trial 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.

Clinical Trial Description

Some orthopaedic surgeons believe that relatively 'young' older patients (aged ≤ 75 years) who have sustained a femoral neck fracture should be treated with hemiarthroplasty (HA) instead of total hip arthroplasty (THA). The rationale behind this belief is that THA is more time consuming, has greater associated surgical morbidity and may increase the risk of hip dislocation and subsequent revision surgery. On the other hand, HA is believed to accelerate acetabular erosion (i.e. wear) over time, which may ultimately lead to the need for conversion surgery from HA to THA. Due to a lack of research in this area, it is unclear how often the development of acetabular erosion in patients after HA actually occurs. This makes it difficult for orthopaedic surgeons to make an informed choice between HA or THA surgery for this patient group. This is an exploratory retrospective study using existing electronic patient data of patients adhering to the inclusion criteria of the study, i.e. patients of ≤ 75 years of age who have had HA after a femoral neck fracture. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
