“…Arthroplasty Today It is instructive to note that the contralateral hip in the reported patient had an isolated revision to a cemented DMC with retention of a polished Charnley stem, which has had favorable reports in combination with dual-mobility articulations [12][13][14][15]. We completely disagree with the authors' statement "Our case and review of the literature may form an argument not to consider DMC for primary cases and placement in younger patients should be performed with caution" as the efficacy of contemporary monoblock implants has been reported [16][17][18][19][20][21]. In addition, results at more than 10 years in THA in patients less than 55 years have been shown to be excellent without an increase in serum cobalt or chromium levels [22].…”

“…Popular theory suggests a decrease in muscle control associated with ligamentous laxity following femoral neck fracturesin elderly patients [10]. Dual mobility cups have gained more interestin primary replacement for femoral neck fractures and revision arthroplasty as they exhibit less wear, restore near normal range of motion with increased implant stability [11,12].…”

Background: Total Hip Arthroplasty (THA) for femoral neck fractures in the elderly is still lauded as one of the most successful surgeries of the century with good short and medium term outcomes. Postoperative dislocation remains the mainset back of hip replacement in the elderly. This study mainly sees keto assess early outcomes of total hiparthroplasty using dual mobility acetabular cup for femoral neckfractures in the elderly with emphasis ondislocation. Patients and Methods:We carried out 80 consecutive total hip replacements using a double articulating acetabular component. We assessed dislocation rates after 6 months and cumulative risks in the years following replacement.Results: After a mean follow-up of 50 months, only 8 (10%) deaths were recorded. We observed 1 case of dislocation at 4 months postoperatively that required revision arthroplasty. No case of instability was recorded. Conclusion:Dual mobility acetabular cups remain suitable implants in the face of postoperative dislocation after total hip replacement for femoral neck fractures in the elderly.

“…Two recent systematic reviews found IPD rates of 1.1 and 0.7% in primary THA and 0.3 and 0.9% in revision THA. 59,60 During IPD, the inner head will typically remain within the acetabular shell after reduction, giving it an eccentric appearance on radiographs. 61 Closed reduction of a dislocated DM component is much more difficult than with a traditional prosthetic head, owing to the increased head size.…”

The Current Role of Dual Mobility Articulations in Total Hip Arthroplasty

The concept of dual mobility (DM) bearings in total hip arthroplasty was first introduced by Professors Gilles Bousquet and Andre Rambert in France in 1974 with the goal of enhancing hip stability. Although DM did not receive U.S. Food and Drug Administration approval for commercial use in the United States until 2009, there has been a surge in popularity of DM implants over the past several years, evidenced by the American Joint Replacement Registry data. The enthusiasm for DM stems from a growing body of literature that supports its use across a range of patient populations, most notably revision hip arthroplasty and high-risk primary scenarios. DM has been shown to effectively reduce the risk of dislocation while also exhibiting excellent survivorship. DM does incur some unique risks, namely, intraprosthetic dissociation, but many of the early concerns with DM have not been realized in the literature and do not seem to negatively impact its long-term survivorship. The exact indications for DM have yet to be defined and remain a matter of debate. It should be considered as an alternative for any primary or revision hip arthroplasty at high risk for postoperative instability. In this article, the authors review the current literature regarding the clinical success of DM implants for a variety of indications, all of which predispose to hip instability. The history, basic biomechanics, modern designs, and unique complications are also discussed.
