Plain English summary of protocol

Background and study aims
Controversy exists regarding the best treatment for independent patients with displaced intracapsular fractures of the proximal fracture. The recognised alternatives are hemiarthroplasty being used in many centres. The advantages of total hip arthroplasty (THA) are a functional benefit over hemiarthroplasty and a reduced risk of revision surgery. The principle criticism is the increased risk of dislocation. We believe that an alternative acetabular component may reduce the risk of dislocation but still provide the functional benefit of total hip arthroplasty in these patients. We therefore propose to investigate the dislocation risk of an alternative acetabular component compared with standard components in total hip arthroplasty for independent patients with displaced intracapsular fractures of the proximal femur. The aim of the study is to draw conclusions on observed differences in the dislocation risk between the study groups at one year post-injury.

Who can participate?
Any patient with an AO/OTA type B3 fracture of the proximal femur.

What does the study involve?
Eligible patients will be randomly allocated to one of two groups: standard THA or the treatment under investigation (dual mobility THA). After the procedure, all patients will be asked to complete outcome questionnaires at 1 month, 4 months and 1 year post injury. These questionnaires will be completed either by telephone or post.

What are the possible benefits and risks of participating?
Both treatments require surgery which carries some risks, but these risks are the same and equal to individuals who do not take part. The risks of surgery include the risks of bleeding, risk of deep vein thrombosis, risk of damage to nerves and blood vessels in the surgical area and the risk associated with the anaesthesia.

Where is the study run from?
The study takes place at University Hospitals Coventry and Warwickshire (UK).

When is the study starting and how long is it expected to run for?
The study is expected to start in May 2013 with recruitment expected to end in May 2014.
