Background / introduction |
---|
This research focuses on acetabular fractures. Acetabular fractures can vary from simple non-displaced fractures to multi-fragmentary, severely displaced fractures. These injuries are treated either conservatively or surgically depending on fracture type, degree of displacement and patient characteristics. Gap and step-off measurements are used to estimate the degree of fracture displacement and guide clinical decision-making regarding choice of treatment as well as estimate risks on conversion to total hip arthroplasty at follow up. Unfortunately, robust data on critical gap and step-off cutoff points and their consequences for hip survival is limited. Furthermore, studies on the relation between residual fracture displacement (i.e. gap and step-off displacement after surgery) and long-term outcomes are limited. |
Research question / problem definition |
---|
This study will assess the correlation between fracture displacement (e.g. gaps and step-offs) and risk on conversion to THP as well as clinical outcome measured by PROMs at long-term follow-up in patients who sustained an acetabular fracture |
