Aims. The aim of this study was to examine the results of the acetabular
distraction technique in achieving implantation of a stable construct,
obtaining biological fixation, and producing healing of chronic
pelvic discontinuity at revision total hip arthroplasty. Patients and Methods. We identified 32 patients treated between 2006 and 2013 who underwent
acetabular revision for a chronic pelvic discontinuity using acetabular
distraction, and who were radiographically evaluated at a mean of
62 months (25 to 160). Of these patients, 28 (87.5%) were female.
The mean age at the time of revision was 67 years (44 to 86). The patients
represented a continuous series drawn from two institutions that
adhered to an identical operative technique. Results. Of the 32 patients, one patient required a revision for aseptic
loosening, two patients had evidence of radiographic loosening but
were not revised, and three patients had migration of the acetabular
component into a more stable configuration. Radiographically, 22
(69%) of the cohort demonstrated healing of the discontinuity. The

Aims. This study sought to establish the prevalence of the cross over
sign (COS) and posterior wall sign (PWS) in relation to the anterior
pelvic plane (APP) in an asymptomatic population through reliable
and accurate 3D-CT based assessment. Materials and Methods. Data from pelvic CT scans of 100 asymptomatic subjects (200 hips)
undertaken for conditions unrelated to disorders of the hip were
available for analysis in this study. A previously established 3D
analysis method was applied to assess the prevalence of the COS
and PWS in relation to the APP. Results. Of the 200 included hips, 24% (48) presented a positive COS and
5.5% (11) presented a positive PWS. A combination of COS and PWS
was observed in 1% (two) of all hips (1%). . Conclusion. The high incidence of
