“…This risk also has been demonstrated by other investigators [35]. Possible explanations for this finding include: extraarticular fatty tissue acting as a fulcrum [15] for dislocation and/or greater risk of suboptimal implant position because of technical difficulties associated with the procedure in patients with high BMI. However, it is not only the amount of weight that plays a role.…”

“…When obesity is defined as a body mass index (BMI) greater than 30 kg/m 2 in adults, obesity is recognized as an independent risk factor for postoperative hip dislocation in several studies [2,6,8,15,18,22,28,35]. However, in these patients with obesity, it is not known whether the risk is only in the early postoperative period or if the risk persists several years after surgery.…”

Background Obesity is associated with an increased risk of dislocation after total hip arthroplasty (THA). However, in patients with obesity, it is not known whether the risk is only in the early postoperative period or whether it persists several years after surgery, and whether having bariatric surgery before undergoing THA and/or receiving a specific device (such as a dual-mobility or constrained acetabular liner) is more effective in terms of decreasing the risk of dislocation. Question/purposes (1) What is the cumulative risk of dislocation in patients with obesity after THA in the absence of a dual-mobility or constrained liner, and is this related to component positioning? (2) Does bariatric surgery before undergoing THA decrease dislocation risk in patients with obesity? (3) Are dual-mobility and constrained liners efficient in preventing dislocation in patients with obesity? Methods At our university-based practice, all surgeons adhered to the following treatment approaches: Before 2000 no dual-mobility implants or constrained liners were used for primary THAs. 2 ) who received standard cups, 85 hips in patients with bariatric surgery before THA using standard cups (with reduction to a BMI \ 30 kg/m 2 ), and 155 hips in patients with obesity who received dual-mobility (when younger than 70 years) or constrained liners (when older than 70 years). All patients received the same implants except for different femoral head diameters (32-mm head with standard cups and 28-mm head with dual-mobility or constrained liners). The patients were followed at routine intervals and were specifically queried about dislocation. All the 670 hips had a minimum followup of 5 years with a mean followup of 14 years (range 5-25 years). At the most recent followup, 101 (15%) hips were lost to followup (respectively, 36 of 215, 34 of 215, five of 85, 24 of 155), which is the same ratio as observed among the underlying populations from which the patients were drawn.Each author certifies that he or she, or a member of his or her immediate family, has no commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.

“…[1,2] While implant impingement [3][4][5] and bony impingement [6][7][8] have been widely investigated, reports of soft-tissue impingement are rare. [9,10] Capsule thickening is sometimes observed in various conditions, such as developmental dysplasia of the hip, [11] osteoarthritis, synovitis, [12] previous surgical procedures and femoro-acetabular impingement. [13] Yamamura et al showed that, in their in vivo open MRI study, femoro-acetabular impingement as well as soft-tissue impingement occurred during hip flexion with internal rotation in normal subjects.…”

“…As part of a prospective study intended to help determine the accuracy of THA components that have been inserted with the use of a navigation system (results reported separately) [6][7][8], 144 consecutive primary THAs were performed in 144 patients using a CT-based fluoroscopic matched navigation system (VectorVision HIP 3.5; BrainLAB, Feldkirchen, Germany), and implanted Pinnacle acetabular cups (DePuy, Warsaw, IN) in all patients. The patients were 121 women and 23 men with a mean age of 65.2 years (range, 30-87 years) at operation.…”

Purpose The use of screws can enhance immediate cup fixation, but the influence of screw insertion on cup position has not previously been measured. The purpose of this study was to quantitatively evaluate the effect of intra-operative screw fixation on acetabular component alignment that has been inserted with the use of a navigation system. Methods We used a navigation system to measure cup alignment at the time of press-fit and after screw fixation in 144 hips undergoing total hip arthroplasty. We also compared those findings with factors measured from postoperative radiographs. Results The mean intra-operative change of cup position was 1.78°for inclination and 1.81°for anteversion. The intraoperative change of anteversion correlated with the number of screws. The intra-operative change of inclination also correlated with medial hip centre. Conclusion The insertion of screws can induce changes in cup alignment, especially when multiple screws are used or if a more medial hip centre is required for rigid acetabular fixation.
