“…Moreover, THA with standard cups following ONFH or FNF has been associated with higher risk of dislocation. 5–7,10,11,15 Again our results were congruent with those reporting the use of DMC; 3 studies on ONFH reported nil dislocation, 20,23,30 and 4 studies on FNF reported a dislocation rate of no more than 2%. 22,24,31,32 Only Nich et al 33 reported a dislocation rate of 6.6% for FNF; however, all were related to technical errors.…”

“…16,17 Recently, multiple reports on second and contemporary generations of DMC have demonstrated excellent results when used in high risk patients. [18][19][20][21][22][23][24] Most of these reports conveyed the results from populations having a single at-risk aetiology. The aim of this study is to report and to compare the outcomes of a series of patients having 1 or several combined risk factors for dislocation, treated by THA with DMC.…”

Introduction: Dual-mobility cups (DMC) are currently used in patients having risk factors of instability. Most of the studies report the use of DMC in patients having a single high-risk variable. The aim of the study was to analyse a continuous series of patients treated with primary total hip arthroplasty (THA) and DMC with different high risk for dislocation. Methods: This is a retrospective study analysing the outcomes of primary THA with DMC in patients at high-risk of dislocation. The sample consisted of 215 patients having 1 of 3 aetiologies or risk factors: (1) young subjects (<55 years); (2) osteonecrosis of the femoral head (ONFH); and (3) femoral neck fracture (FNF). Results: With a mean follow-up duration of 70 ± 24.7 months, the findings showed the following: 2 patients had dislocated their hip following motor vehicle accidents; 1 patient had a traumatic femoral peri-prosthetic fracture; and 1 patient had an acute infection. No intra-prosthetic dislocation or aseptic loosening were encountered. No radiolucent lines were observed on the acetabular side. The mean modified Hip Harris Score was 96.6 ± 7.4%. Out of 186 patients, 170 (90.1%) would label their operated hip as a “forgotten hip”. 78 out of the 84 patients (92.8%) who used to practice oriental sitting and/or ablution for prayers were able to return to their usual daily activities of extreme hip position and 74 out of the 84 patients (88%) described their operated hip as “a forgotten hip”. No correlation was found between any of the studied variables. Discussion: The findings of this series of patients at high risk of dislocation showed excellent clinical and radiological results with very few complications. The use of DMC seems to counteract the impact of some aetiologies/risk factors that could lead to higher instability. Most patients practising extreme hip positions resumed their usual practices.

“…However, we were concerned about post-operative dislocation. Considering the presence of some acetabular damage during the pre-operative examination and intraoperative findings, THA using the dual mobility system with substantial resistance to dislocation was indicated [ 7 , 8 ]. During the post-operative THA evaluation, the cup inclination angle was 28°, which was rather low, but the combined anteversion angle was within the optimum range [ 9 ] of 57°.…”

Introduction: Atraumatic hip dislocation after short femoral nail (SFN) fixation for an intertrochanteric fracture is extremely rare. Case Report: An 84-year-old woman presented with an atraumatic posterior hip dislocation that occurred 8 years after SFN fixation for an intertrochanteric hip fracture. She experienced an acute-onset left hip pain when standing up from a sitting position while bathing at a day care facility. We performed total hip arthroplasty (THA) with a dual mobility system. During the post-operative THA evaluation, the combined anteversion angle was within the optimum range of 57. However, the dislocation recurred after the THA. During the revision THA, a dual mobility system was used to moderately extend the stem neck. Measures were adopted to strain the posterior soft tissues of the hip joint. We speculated that the posterior hip joint capsule ruptured because the support of the posterior hip joint was weak after the intertrochanteric hip fracture. At the final follow-up visit at 6 months after the operation, the hip joint pain had disappeared, and her activities of daily living recovered to almost the same level as her preinjury activities. Conclusions: We should consider the lack of support of posterior soft tissues as a cause of this atraumatic posterior hip dislocation following intertrochanteric fracture fixation. Keywords: Atraumatic posterior hip dislocation, post-operative state of intertrochanteric hip fracture, short femoral nail, total hip arthroplasty, dual mobility system.

The Current Role of Dual Mobility Articulations in Total Hip Arthroplasty

et al. 2018

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.
