Research proposal abstract
Dislocation is the most common complication after total hip arthroplasty (THA), the risk for dislocation after THA varies from 0.4%-8.7% for primary procedures. Several methods are available to correct instability of THA, like dual mobility cups and constrained acetabular liners (CAL). Revision surgery is recommended in cases of recurrent instability. Research application form LROI 1-1-2018 The aim of our study is to determine the use, patient, procedure and prosthesis characteristics of constrained acetabular liners in primary as well as revision total hip arthroplasties in the Netherlands. Secondly, what is the revision rate (especially for dislocation) for primary and re-revision rate for revision THAs with a constrained acetabular liner in the Netherlands?
