  • dual mobility for Recurrent Dislocation double trouble
    Orthopaedic Proceedings, 2018
    Co-Authors: Paul F Lachiewicz
    Abstract:

    Dual mobility components for total hip arthroplasty provide for an additional articular surface, with the goals of improving range of motion, jump distance, and overall stability of the prosthetic hip joint. A large polyethylene head articulates with a polished metal acetabular component, and an additional smaller metal head is snap-fit into the large polyethylene. New components have been released for use in North America over the past three years. In some European centers, these components are routinely used for primary total hip arthroplasty. However, their greatest utility may be to manage Recurrent Dislocation in the setting of revision total hip arthroplasty. Several small retrospective series have shown satisfactory results for this indication at short- to medium-term follow-up times. However, there are important concerns with polyethylene wear, late intra-prosthetic Dislocation, and the lack of long-term follow-up data. These components are an important option in the treatment of Recurrent disloca...

    Abstract:

    Dual mobility components for total hip arthroplasty provide for an additional articular surface, with the goals of improving range of motion, jump distance, and overall stability of the prosthetic hip joint. A large polyethylene head articulates with a polished metal acetabular component, and an additional smaller metal or ceramic head is snap-fit into the large polyethylene. In some European centers, these components are routinely used for primary total hip arthroplasty. However, their greatest utility will be to prevent and manage Recurrent Dislocation in the setting of revision total hip arthroplasty. Several retrospective series have shown satisfactory results for this indication at medium-term follow-up times. The author has used dual mobility components on two occasions to salvage a failed constrained liner. At least one center reports that dual mobility outperforms 40mm femoral heads in revision arthroplasty. Modular dual mobility components, with screw fixation, are the author9s first choice for the treatment of Recurrent Dislocation, revision of failed metal-metal resurfacing, total hips, unipolar arthroplasties, and salvage of failed constrained liners. There are concerns of elevated metal levels with one design, and acute early intra-prosthetic dissociation following attempted closed reduction. Total hip surgeons no longer cement Charnley acetabular components, use conventional polyethylene, autologous blood donation, or a drain; now constrained components join these obsolete techniques! In 2017, a dual mobility component, rather than a constrained liner, is the preferred solution in revision surgery to prevent and manage Recurrent Dislocation.

    Abstract:

    Dual mobility components for total hip arthroplasty provide for an additional articular surface, with the goals of improving range of motion, jump distance, and overall stability of the prosthetic hip joint. A large polyethylene head articulates with a polished metal acetabular component, and an additional smaller metal head is snap-fit into the large polyethylene.

However, their greatest utility may be to manage Recurrent Dislocation in the setting of revision total hip arthroplasty. Several small retrospective series have shown satisfactory results for this indication at short- to medium-term follow-up times. However, there are important concerns with polyethylene wear, late intra-prosthetic Dislocation, and the lack of long-term follow-up data. These components are an important option in the treatment of Recurrent Dislocation in younger patients, revision of failed metal-metal resurfacing, and salvage of failed constrained liners. Until further long-term results are available, caution is advised in the routine use of dual mobility components in primary or revision total hip arthroplasty.

  • modular revision for Recurrent Dislocation of primary or revision total hip arthroplasty
    Journal of Arthroplasty, 2004
    Co-Authors: Paul F Lachiewicz, Elizabeth S Soileau, John Ellis
    Abstract:

    Abstract Two surgeons who used the same implants and surgical approach performed 23 revisions for Recurrent Dislocation of modular total hip arthroplasty (THA) with retention of components. For 17 primary hips, there was a mean of 3.8 (range, 2–10) Dislocations before revision. Fifteen hips had exchange of the acetabular liner, 13 had a change in neck length, and 5 had a change in size of the femoral head. At a mean follow-up of 4 years (range, 2–7 years), 14 patients (82%) had no further Dislocation, 1 had 1 additional Dislocation, and 2 required additional surgery. For the 6 revision procedures, the mean number of Dislocations was 3.8 (range, 2–10) before re-revision. Liner exchange was performed in 4 hips, neck length changed in 3 hips, and head size increased in 2 hips. At a mean follow-up of 3 years (range, 2–5 years), only 3 patients (50%) had no further Dislocation, and 2 required additional surgery. Modular revision can be a successful method of treatment of Recurrent Dislocation after primary THA, but is much less successful after revision THA.

  • re Dislocation after revision total hip arthroplasty for Recurrent Dislocation a multicentre study
    International Orthopaedics, 2017
    Co-Authors: Kensei Yoshimoto, Yasuharu Nakashima, Shigeo Aota, Ayumi Kaneuji, Kiyokazu Fukui, Kazuo Hirakawa, Nariaki Nakura, Koichi Kinoshita, Masatoshi Naito, Yukihide Iwamoto
    Abstract:

    Purpose Although most case of Dislocations after total hip arthroplasty (THA) can be managed with conservative treatment, Recurrent Dislocation may require surgical intervention. This multicentre study was conducted to evaluate the re-Dislocation rate after revision THA for Recurrent Dislocation, and to determine the risk factors for re-Dislocation.

  • Re-Dislocation after revision total hip arthroplasty for Recurrent Dislocation: a multicentre study

    Abstract:

    Although most case of Dislocations after total hip arthroplasty (THA) can be managed with conservative treatment, Recurrent Dislocation may require surgical intervention. This multicentre study was conducted to evaluate the re-Dislocation rate after revision THA for Recurrent Dislocation, and to determine the risk factors for re-Dislocation. We retrospectively reviewed the 88 hips in 88 patients who underwent revision THA for Recurrent Dislocation at five institutions between 1995 and 2014. The mean patient age at surgery was 68.5 years and the mean follow-up period was 53.1 months. Multivariate logistic regression was performed to identify risk factors for re-Dislocation. Sixteen hips in 16 patients (18.2 %) re-dislocated at a mean of 25.5 months (range, 1-83 months) after revision THA. Multivariate analysis identified osteonecrosis of the femoral head (odds ratio [OR] = 5.62 vs. osteoarthritis) and a femoral head size < 32 mm (OR = 3.86) as independent risk factors for re-Dislocation. Eight hips required additional revision THA for re-Dislocation. The re-Dislocation rate after revision THA for Recurrent Dislocation remains high, suggesting the need for prevention measures. We recommend the use of a femoral head size ≥ 32 mm.

  • five to thirteen year results of a cemented dual mobility socket to treat Recurrent Dislocation
    International Orthopaedics, 2017
    Co-Authors: Moussa Hamadouche, David Biau, Thierry Musset, Francois Gaucher, Mickael Ropars, Camille Rodaix, Jean Pierre Courpied, Denis Huten
    Abstract:

    Purpose Dual mobility (DM) socket has been associated with a low rate of Dislocation following both primary and revision total hip arthroplasty (THA). However, little is known about the long-term efficiency of DM in the treatment of THA instability. The purpose of this retrospective study was to evaluate the outcome of a cemented DM socket to treat Recurrent Dislocation after a minimum of five year follow-up.

    Co-Authors: Moussa Hamadouche, David Biau, Denis Huten, Thierry Musset, Francois Gaucher
    Abstract:

    The treatment of Recurrent Dislocation after total hip arthroplasty remains challenging. Dual mobility sockets have been associated with a low rate of Dislocation but it is not known whether they are useful for treating Recurrent Dislocation. We therefore asked whether a cemented dual mobility socket would (1) restore hip stability following Recurrent Dislocation; (2) provide a pain-free and mobile hip; and (3) show durable radiographic fixation. We retrospectively reviewed 51 patients treated with a cemented dual mobility socket for Recurrent Dislocation after total hip arthroplasty between August 2002 and June 2005. The mean age at the time of the index procedure of was 71.3 years. Of the 51 patients, 47 have had complete clinical and radiographic evaluation data at a mean followup of 51.4 months (range, 25-76.3 months). The cemented dual mobility socket restored complete stability of the hip in 45 of the 47 patients (96%). The mean Merle d'Aubigné hip score was 16 ± 2 at the latest followup. Radiographic analysis revealed no or radiolucent lines less than 1 mm thick located in a single acetabular zone in 43 of 47 hips (91.5%). The cumulative survival rate of the acetabular component at 72 months using revision for Dislocation and/or mechanical failure as the end point was 96% ± 4% (95% confidence interval, 90%-100%). A cemented dual mobility socket was able to restore hip stability in 96% of Recurrent dislocating hips. However, longer-term followup is needed to ensure that Dislocation and loosening rates will not increase.
