INTRODUCTION: Osteonecrosis of the femoral head (ONFH) remains a therapeutic challenge for patients undergoing total hip arthroplasty (THA). The majority of these patients are young with high functional demand, and show an increased risk of dislocation following surgery than patients with osteoarthritis. The use of double mobility cup (DMC) has been linked with lower rates of complications when compared to conservative cups; however, the literature is scarce over DMC results in patients with ONFH...

BACKGROUND: The choice between performing total hip arthroplasty (THA) or hemiarthroplasty (HA) is not straightforward in older patients with femoral neck fracture, particularly when co-morbidities are factored in. This led us to carry out a case-control study to determine 1) the rate of mechanical complications for these two types of implants, and 2) the rate of medical complications and mortality. HYPOTHESIS: THA with dual mobility cup (DM) will result in fewer mechanical complications than HA...

A 77-year-old man sustained an acetabular fracture after falling from a staircase and landing on his right side. He fractured the anterior column of his acetabulum and the quadrilateral plate. He underwent a single-stage open reduction and internal fixation of the fracture combined with a dual mobility total hip arthroplasty (THA). He sustained a traumatic hip dislocation 1 month postoperatively. Closed reduction was attempted at another hospital, and the femoral stem was pulled out. We believe this was caused by the polyliner being hitched either to the acetabular cup or in the soft tissues around the ilium...

AIMS: Instability remains a challenging problem in both primary and revision total hip arthroplasty (THA). Dual mobility components confer increased stability, but there are concerns about the unique complications associated with these designs, as well as the long-term survivorship. MATERIALS AND METHODS: We performed a systematic review of all English language articles dealing with dual mobility THAs published between 2007 and 2016 in the MEDLINE and Embase electronic databases...

BACKGROUND: Dislocation rates in posterior total hip arthroplasty (THA) range between 2% and 5%, but long-term course (recurrence of dislocation or revision surgery) is not known, most series having short follow-up or small populations. We therefore conducted a retrospective study on a large series, to determine long-term rates of recurrence and surgical revision and recurrence risk factors. HYPOTHESIS: Long-term follow-up of a large cohort of THA dislocations enables recurrence rate and factors to be determined...

BACKGROUND: Parkinson disease (PD) results in severe limitation in ambulation caused by abnormality of gait and posture. The rate of complications, including fractures and dislocation after total hip arthroplasty (THA), can be higher among these patients. The goal of this study was to investigate the long-term outcomes of primary and revision THAs with cementless dual mobility implants. METHODS: This retrospective study examines 59 PD patients who had surgery between 2002 and 2012...

BACKGROUND: Recurrent instability remains a challenge after revision total hip arthroplasty (THA). We report the outcomes of cementing a cementless dual mobility (DM) component into a stable acetabular shell for the treatment and/or prevention of instability in revision THA. METHODS: Eighteen patients (18 THAs) undergoing revision THA with a specific monoblock DM construct cemented into a new acetabular component or an existing well-fixed component from 2011 to 2014 were retrospectively reviewed...

INTRODUCTION: We used a matched cohort of 231 cases of revision of primary dual-mobility cups (DMC) total hip arthroplasty (THA) and 231 cases of fixed cups (FC) THA, to determine whether (i) revision for infection was more frequent when using DMC-THA than FC-THA; (ii) Causes for revision were significantly different. METHODS: The French Society of Orthopaedics and Traumatology carried out a prospective multicentre study from 2010 to 2011. The inclusion criterion was an exhaustive collection of 1st revision THA (at least 1 component revised, re-revision excluded)...

Postoperative dislocation is a challenging complication after total hip arthroplasty (THA) that affects patient outcome worldwide. Instability is one of the main complications with rates exceeding 20% in some series. Currently, alternative acetabular components are available with dual mobility (DMTHA) bearing surfaces and larger femoral head size that may reduce the risk of dislocation, yet provide the functional benefit of standard single mobility (STHA) bearing surface THA. However, whether STHA, big femoral head (BTHA) and DMTHA should be used is still controversial...

BACKGROUND: Dislocation following total hip arthroplasty (THA) remains a significant clinical problem. Few studies have focused on the use of dual mobility (DM) components in the setting of first-time revision for instability following THA. Here, we investigate patient outcomes following first-time revision THA with DM components for a diagnosis of instability. METHODS: Institution-wide revision THAs using DM components performed between 2010 and 2013 were identified...

INTRODUCTION: Although total hip arthroplasty (THA) is superior to bipolar hemiarthroplasty (BHA) for displaced femoral neck fracture in terms of hip pain, function and reoperation rate, THA has a higher rate of dislocation. The direct anterior approach (DAA) and a dual mobility cup (DMC) are associated with lower rates of dislocation. The aim of this study was to investigate the outcomes of THA compared with BHA, and in those patients who had a THA we investigated those with a DMC (DMC-THA) and compared them with those had a single conventional cup (Single cup-THA)...

INTRODUCTION: Dual mobility (DM) total hip arthroplasty (THA) may reduce dislocation risk, but might increase the risk of high polyethylene (PE) wear due to double wearing surfaces. METHODS: 127 patients (97 female) with 129 hips operated with THA after displaced femoral neck fracture FNF between 2005 and 2011, were seen for a cross-sectional clinical follow-up. Acetabular components were Saturne® DM cups with 28mm chrome-cobalt heads in UHMWPE. Cementless cups (n = 73) were hydroxyapatite coated...

PURPOSE: Revision of failed modular metal-on-metal total hip replacement (MoM-THA) can be technically difficult. A dual mobility liner can help to salvage a well-fixed acetabular component. The present paper reports the clinical and radiographic outcome of revision of failed Birmingham modular MoM-THA using a dual mobility liner. METHODS: The present study reports on ten patients (3 female and 7 male) with 11 revision THAs. Patients underwent revision an average of 51 months (range 40-73 months) after index procedure...

INTRODUCTION: The concept of a dual mobility (DM) cup has been in existence for more than 40 years and was initially popularized in Europe. Only recently has it started to garner attention in the United States. Its design, consisting of a small femoral head articulating within a larger polyethylene (PE) insert, which articulates with an outer shell, has found increasing use in patients that are at risk for post-operative dislocations. This case report describes a case of recurrent total hip arthroplasty (THA) dislocation managed with the implantation of a DM cup with an acute intraprosthetic dislocation of the DM construct...

After decades of use in Europe, dual-mobility (DM) components for total hip arthroplasty (THA) were approved by the US Food and Drug Administration (FDA) in 2011 for use in the United States. DM-THAs are designed with an inner articulation between the femoral head and a larger polyethylene insert, and an outer articulation between the mobile polyethylene and a highly polished metal insert, to increase motion and minimize impingement. Intraprosthetic dissociation (IPD), defined as separation of the femoral head from the inner polyethylene articulation, is usually caused by polyethylene wear, and occurs 3 to 10 years after implantation...

INTRODUCTION: Dislocation after total hip arthroplasty (THA) is a leading reason for surgical revision. The risk factors for dislocation are controversial, particularly those related to the patient and to the surgical procedure itself. The differences in opinion on the impact of these factors stem from the fact they are often evaluated using retrospective studies or in limited patient populations. This led us to carry out a prospective case-control study on a large population to determine: 1) the risk factors for dislocation after THA, 2) the features of these dislocations, and 3) the contribution of patient-related factors and surgery-related factors...

BACKGROUND: Prosthetic dislocation of total hip arthroplasty (THA) is a common cause for revision surgery. Dual-mobility (DM) bearings were introduced to mitigate complications; however, their performance in younger patients is unknown. This study compared results of patients <55 years of age with DM vs fixed-bearing (FB) primary THA. METHODS: Our total joint registry was used to evaluate primary THA patients <55 years of age, and then, an age-matched comparative analysis was performed for 136 THAs using third-generation highly cross-linked polyethylene DM bearings and 136 THAs using FB from the same manufacturer with mean follow-up of 3...

BACKGROUND: Conversion of hemiarthroplasty to total hip arthroplasty (THA) has a historically high, up to 20%, postoperative dislocation rate. As such, dual-mobility (DM) constructs are an attractive option to mitigate this complication. We analyzed survivorship free of revision, complications, and clinical outcomes of hemiarthroplasties conversion to THAs utilizing DM constructs compared with large femoral heads (≥36 mm). METHODS: Conversion of 16 hemiarthroplasties to THAs with a specific DM construct compared with 13 conversions utilizing large femoral heads (≥36 mm) from 2011 to 2014 were reviewed...

BACKGROUND: Total hip arthroplasty (THA) using dual-mobility (DM) design permits larger hip range of motion. However, it is unclear how it benefits the patients during activities of daily living. The purpose was to compare kinematic variables of the operated limb between THA patients using either DM or single-bearing (SB) implants during a squat task. METHODS: Twenty-four THA patients were randomly assigned to either a DM or SB implant and matched to 12 healthy controls (CTRLs)...
