Background Conventional radiographs are routinely used to evaluate acetabular bone loss
as part of the follow-up in patients who undergo total hip arthroplasty (THA). The objective of …

Purpose: The reconstruction of severe acetabular defects, caused by failed hip prostheses,
is difficult and complex. Current radiographic descriptions of the defects are inadequate. We …

Three classifications for assessment of acetabular bone loss were evaluated for their
reliability. The 3 systems assessed were the system described by Gross, the system …

In 18 human pelvis specimens we produced different acetabular defects according to
Paprosky. Standardized X-rays of these specimens were taken, and these X-rays were …

To determine observer variation in the detection of acetabular bone deficiencies, 42 pairs of
frontal (AP) and lateral hip radiographs and CT studies for total hip arthroplasty patients …

Preoperative classification of acetabular bone loss in revision total hip arthroplasty has been
problematic. An evidence-based approach involves having a validated and widely accepted …

As the number of primary total hip arthroplasty (THA) procedures performed continues to
rise, the burden of revision THA procedures is also expected to increase. Proper evaluation …

Reconstruction of severe acetabular defects during revision hip arthroplasty presents a
significant surgical challenge. Such defects are associated with significant loss of host bone …

Computed tomography (CT) scanning is a useful tool in many areas of orthopedics. This
prospective study reviews the authors' experience with CT scans in 73 patients studied prior …

Anteroposterior (AP) x-rays provide limited information about size and location of acetabular
osteolytic lesions after total hip arthroplasty (THA). In the study reported here, we sought to …
