A retrospective review was conducted to evaluate the mid-term results of the Längsovalen Revisionspfanne oblong revision cup. From July 1995 to March 2000, 41 acetabular revision surgeries were performed for aseptic loosening of the acetabular cup. The acetabular defects were classified as type 2A to 3B, according to Paprosky's criteria. Morselized bone grafts were used in 19 cases (45.2%) to fill cavitary defects. The mean postoperative follow-up was 63.5 months (range, 40-99 months). Clinical assessment at follow-up showed a significantly improved mean Harris Hip Score from 46 points preoperatively to 82.2 points postoperatively, whereas the x-ray examination did not show any sign of loosening of the cups. Data analysis showed that significantly better results were correlated with restoring the hip rotation center and reducing leg length discrepancy.

Periprosthetic fractures and their associated complications present significant challenges for orthopaedic surgeons. It is important to provide an overview of the current management of periprosthetic fractures, including techniques for osteosynthesis and revision total hip and knee arthroplasty, as well as special considerations for periprosthetic acetabular fractures, periprosthetic tibial fractures, and interprosthetic femur fractures. In addition, the guiding principles for the management of potential subsequent complications including infection, nonunion, and instability are discussed.

Aims: The purpose of this study was to directly compare the Modular Dual Mobility (MDM) Mobile Bearing Hip System (Stryker, USA) and large femoral heads (LFHs) in revision total hip arthroplasties (THAs) at mid-term follow-up, with specific emphasis on survival free of re-revision for dislocation, any re-revision, dislocation, and the risk of metal-related complications.
Methods: We identified 299 revision THAs performed at a single tertiary care academic institution from March 2011 to July 2014. Aseptic loosening of the acetabular component (n = 65), dislocation (n = 58), and reimplantation as part of a two-stage exchange protocol (n = 57) were the most common reasons for index revision.

Aims: Dislocation is a major concern following total hip arthroplasty (THA) for osteoarthritis (OA). Both dual-mobility components and standard acetabular components with large femoral heads are used to reduce the risk of dislocation. We investigated whether dual-mobility components are superior to standard components in reducing the two-year dislocation and revision risk in a propensity-matched sample from the Danish Hip Arthroplasty Register (DHR).

Aims: The Exeter femoral stem has a cemented, polished taper-slip design, and an excellent track record. The current range includes short-length options for various offsets, but less is known about the performance of these stems. The aim of this study was to compare the survival of short-length stems with standard-length Exeter stems.

Background: Obesity has been consistently proven to be associated with an increased risk of dislocation following total hip arthroplasty (THA). As the prevalence of obesity continues to rise globally, it is of vital importance to minimise risks, including dislocation rates, in these patients undergoing THA.
Methods: We describe a series of patients with obesity, morbid obesity (BMI ≥ 40) and super-obesity (BMI ≥ 50) undergoing THA at our institution over a 10-year period using a dual-mobility acetabular cup.
