Primary ArthroplastyEffect of Acetabular Component Positioning on Functional Outcomes in Primary Total Hip Arthroplasty
Section snippets
Materials and Methods
Ethics approval from our institutional research ethics board was obtained. Fellowship-trained arthroplasty surgeons, with high-volume practices performed the THAs between 2003 and 2011. Patients were identified with the use of our institutional arthroplasty database. Further patient demographics, including their age, sex, date of procedure, side operated on, and implant details were extracted from the database. Postoperative Western Ontario and McMaster Osteoarthritis Index (WOMAC), Harris hip
Results
The study population included 1241 hips with 502 males (40.5%) and 739 females (59.5%). The average length of clinical follow-up was 2.32 years. Mean BMI was 29.53 ± 6.18 kg/m2. A total of 580 hips (46.7%) were left sided and 661 (53.3%) were right sided. The mean absolute position of the population included 21.7 ± 11.9 degrees of anteversion and 44.4 ± 6.9 degrees of inclination angle. The range of anteversion in our cohort was between −19.1 and 58.5 degrees. The range of inclination angle was
Discussion
Outcome measurements are important to clinical research as they allow us to evaluate the effectiveness of our interventions [33]. Their use in improving quality of care cannot be understated as functional outcome measures allow us to judge outcomes from a patient perspective [34]. Generic outcome measures, such as SF-12, provide insight into patients' general health status including physical symptoms, function, and emotional dimensions of health. They may not, however, be sensitive in their

Variability in Acetabular Component Position in Patients Undergoing Direct Anterior Approach Total Hip Arthroplasty Who Have Concomitant Spine Pathology
2022, Journal of ArthroplastyCitation Excerpt :Accurate placement and positioning of the acetabular cup plays a key role in determining the outcome of THA. Acetabular orientation is an important factor long known to influence a variety of outcomes such as dislocations [2,3], range of motion [18,19], noise [20], impingement [4], and patient-reported outcome measures [21]. Placement of acetabular components was initially guided by the literature suggesting that an acetabular inclination of 40° ± 10° and anteversion of 15° ± 10° predicted lower risk of future complications [3].

2017, Journal of ArthroplastyCitation Excerpt :None of these patients experienced a complication or underwent a revision procedure. Recent studies have called the Lewinnek “safe zones” into question, reporting no direct correlation of the safe zones on patient outcome scores or complications [37,38]. Abdel et al [37] reported the majority of contemporary THA dislocations to occur within the Lewinnek safe zone, concluding stability is likely multifactorial and the ideal cup position for some patients might lie outside the Lewinnek safe zone.
