“…Guyen et al [15] reported migration of one (0.6%) noncemented acetabular component in addition to three fully hydroxyapatite-coated femoral components. As expected, because of short followup (range, 2-5 years), no tilting, migration, or IPD was recorded in the Epinette et al [11] study. Similarly, in a study of 20 primary THAs in patients who received dual-mobility cups by Mohammed et al [20], there was no evidence of loosening.…”

“…Guyen et al [15] reported improvement in HHS from preoperatively (mean, 40; range, 11-100) to 83 (range, 25-100) at the latest followup. Similarly, in the Epinette et al [11] study, they reported mean HHS of 98 and 82 for the\70 years of age and C 70 years of age cohorts at final followup, respectively. In the Hamadouche et al [16] study, the mean Merle d'Aubigné functional hip score increased from 11 (range, 6-16) preoperatively to 17 (range, 9-18) at latest followup.…”

“…Dual-mobility articulations may help decrease instability after THA [3,5,6,8,10,11,13,15,16,20,24,26]. This is likely the result of the increased effective size of the femoral head as well as the expanded impingement-free ROM.…”

“…Furthermore, Guyen et al [15] performed a study on 167 dual-mobility hips and reported no dislocations at a minimum followup of 2 years with a 5-year cup survivorship proportion of 96%. Moreover, Epinette et al [11] analyzed 437 primary cemented THAs and noted a 100% cup survivorship for patients younger than 70 years of age and 99.7% for patients older than 70 years of age at minimum 2-year followup. Similar to our study, Boyer et al [6] reported a final followup mean HHS of 92 (SD, 1.9) in their retrospective study of 240 hips with a minimum followup of 18 years.…”

“…These articulations work by containing a three-component and three-joint system: a socket, a free (not fixed) polyethylene liner, and a head. Dual-mobility articulations are commonly used in the revision setting [17]; however, there is a relative paucity of studies evaluating their use in primary THA [3,5,6,8,10,11,13,15,16,20,24,26]. The present study similarly evaluates a dual-mobility articulation; however, it is different in design from most of the aforementioned studies.…”

Background Dislocation complicates 1% to 5% of primary total hip arthroplasties (THAs). As a result, some surgeons consider dual-mobility articulations, which are usually used in the revision setting to decrease the likelihood of dislocation, as an option for primary THA. However, few studies have evaluated their use in this setting. Questions/purposes (1) What is the cup survivorship when the dual-mobility articulation is used in the setting of primary THA? (2) What are the clinical outcomes with this approach? (3) What are the radiographic outcomes? (4) What are the complications of dual-mobility articulations in primary THA? Methods Between 2011 and 2013, the five participating surgeons performed 495 cementless primary THAs. During that time, one of the five surgeons used dual-mobility articulations for all THAs, and the other four used it whenever the acetabular cup size was 52 mm or greater to enable a 28-mm head. Of the 495 patients, 453 (92%) were performed using this device. Smaller patients were treated with a standard THA.

Reducing the distal profile of dual mobility liners can mitigate soft-tissue impingement and liner entrapment without affecting mechanical performance

et al. 2015

Soft‐tissue impingement with dual mobility liners can cause anterior hip pain and intra‐prosthetic dislocation. The hypothesis of this study was that reducing liner profile below the equator (contoured design) can mitigate soft‐tissue impingement without compromising inner‐head pull‐out resistance and hip joint stability. The interaction of conventional and contoured liners with anterior soft tissues was evaluated in cadaver specimens via visual observation and fluoroscopic imaging. Resistance to inner‐head pull‐out was evaluated via finite element analyses, and hip joint stability was evaluated by rigid‐body mechanics simulation of dislocation in two modes (A, B). Cadaveric experiments showed that distal portion of conventional liners impinge on anterior hip capsule and cause iliopsoas tenting at low flexion angles (≤30°). During hip extension, the rotation imparted to the liner from posterior engagement with femoral neck was impeded by anterior soft‐tissue impingement. The iliopsoas tenting was significantly reduced with contoured liners (p ≤ 0.04). Additionally, the contoured and conventional liners had identical inner‐head pull‐out resistance (901 N vs. 909 N), jump distance (9.4 mm mode‐A, 11.7 mm mode‐B) and impingement‐free range of motion (47° mode‐A, 29° mode‐B). Thus, soft‐tissue impingement with conventional dual mobility liners may be mitigated by reducing liner profile below the equator, without affecting mechanical performance. © 2015 Orthopaedic Research Society.
