Background Pelvic discontinuity presents unique treatment dilemmas and is one of the most difficult problems encountered during revision total hip arthroplasty (THA). This clinical entity is often chronic secondary to osteolysis, resulting in significant acetabular bone loss, but can also…
Background Periprosthetic pelvic discontinuity is the loss of continuity between the superior and inferior hemipelvis involving the floor and both columns of the acetabulum because of either fracture or bone loss. The prevalence of pelvic discontinuity is challenging to assess;…
Background Acetabular reconstruction in the presence of significant or severe acetabular bone loss can be achieved in different ways. Classification of the expected bone loss is important. Similarly, patient characteristics and clinical experience should be considered when determining how best…
Introduction Severe acetabular bone loss poses a challenging reconstructive problem in revision total hip arthroplasty (THA), with some of the most complex patterns seen in Paprosky type IIIA and IIIB defects. Even in the absence of chronic pelvic discontinuity, the…
Background Distortion of the acetabulum is a common finding after the removal of failed acetabular components. Reconstruction of such defects is a necessity for any orthopaedic surgeon performing revision total hip arthroplasty (THA) procedures, as the creation of a type…
Background The Paprosky classification of acetabular bone loss was established in 1994 to define the severity of bone loss and to suggest a revision algorithm to obtain a stable acetabular reconstruction. , The treatment is based on the location and…
Background Acetabular bone loss is a technical challenge encountered at the time of revision total hip arthroplasty (THA). The severity of bone loss can be diverse, ranging from minimal deformities with intact columns (Paprosky type I) to complete loss of…
Background As the popularity of total hip arthroplasty (THA) continues to rise, there is expected to be a concomitant increase in the number of revision procedures. Revision of the acetabular component is regarded as one of the most challenging aspects…
