The morphology of the
acetabular margin was also documented as either curved, straight, angular or irregular according to Govsa et al.
Conservative treatment of
acetabular fractures: epidemiology and medium-term clinical and radiological results.
In our patient series, aseptic loosening was mostly seen in patients who underwent the revision of the
acetabular components, a finding in contrast to other studies that reported the highest prevalence of aseptic loosening with femoral components (11, 18, 19).
(23) reported that their patients with
acetabular dysplasia had associated cam deformity.
Another variant of the
acetabular roof is the stellate crease, which is typically an arthroscopic finding only.
To achieve an optimal press-fit, under reaming of 1 to 2mm to the templated
acetabular cup is required5.
Potential causes of type II registration errors include: the probe fell into a cyst not represented on the virtual bone model, osteophytes represented on the virtual model were removed prior to registration, points that were probed are outside of the segmented section on the virtual bone model, or the probe was not adequately anchored on the bone but rather sliding on the
acetabular surface.
An alternative form of surgical management is the PAO surgical technique often used for pincer-type impingement to reduce
acetabular retroversion, and is one of the few surgical approaches to have an association as a sex-specific treatment secondary to the increased prevalence of pincer-type morphology in the female population.
The only trans-operative complication was the difficulty to rotate the caudal
acetabular rim due to osteotomy and not ostectomy of the pubic segment in a single patient.
Between December 2004 and December 2007, Biomet devices comprised a cemented ReCap[TM] femoral component and an uncemented Magnum[TM]
acetabular component (Biomet, Warsaw, Indiana) and were used in an off-label fashion for total hip resurfacing.
showed many complications after THA such as dislocation, aseptic loosening, or breakage of the implant in the early postoperative period because patients with this condition have inadequate muscle tension and complex femoral and
acetabular deformities including excessive femoral anteversion, coxa valga, and leg-length inequality [10].
