Abstract
Acetabular liner dissociation is a rare complication of Total Hip Arthroplasty (THA) which requires urgent revision surgery. A case is presented in which the correct diagnosis was not appreciated on two separate Emergency Department attendances. The typical symptoms, signs, and radiological features are outlined and the importance of considering a rare complication following a commonly performed procedure is highlighted.
Highlights
Total Hip Arthroplasty (THA) remains one of the most frequently performed orthopaedic procedures performed worldwide [1,2,3]
Acetabular liner dissociation is a serious but rare complication following THA that is specific to the modern uncemented acetabular component
The most recent National Joint Registry (NJR) Report shows that over 76,000 primary THA procedures were performed in England, Wales, and Northern Ireland in 2013, with uncemented acetabular components implanted in 65.4% of cases
Summary
Total Hip Arthroplasty (THA) remains one of the most frequently performed orthopaedic procedures performed worldwide [1,2,3]. Surgery involves implantation of both a femoral and acetabular component, with options for either cemented or uncemented fixation depending on Surgeon preference. The modern uncemented acetabular component is modular in design and provides several theoretical advantages. One of the primary attractions is the ability to implant alternative bearing surfaces with improved wear characteristics. The modular design permits certain conservative revision options in the event of early infection, late polyethylene wear, or recurrent dislocation [4]
