Bone cement implantation syndrome in hip arthroplasty: Frequency, severity and prevention.

Introduction: Cemented femoral implants incur a serious risk of potentially fatal accidents in case of bone cement implantation syndrome (BCIS). As French data are sparse regarding this issue, Orthorisq, the official accreditation body for orthopedic surgeons, conducted an inter-professional survey: 1) to assess the frequency of BCIS, 2) to analyze risk factors related to the patient and to professional practices, and 3) to set out guidelines to reduce frequency and/or severity.

Hypothesis: French data on BCIS are underestimated and need updating to ease communication between colleagues.

French Hip & Knee Society classification of short-stem hip prostheses: Inter- and intra-observer reproducibility.

Introduction: In total hip replacement (THR), a short stem theoretically provides more physiological force transfer to the proximal femur, conserves bone stock and facilitates minimally invasive surgery. On the other hand, such implants involve a learning curve and incur risk of malpositioning or fracture and of secondary mobilization. There are several types of short stem, and classification is needed.

Bleeding and thromboembolism risk of standard antithrombotic prophylaxis after hip or knee replacement within an enhanced recovery program.

Introduction: Prevention of venous thromboembolism (VTE) generally consists of low molecular weight heparin (LMWH) or direct oral anticoagulants (DOACs) after total hip arthroplasty (THA) or total knee arthroplasty (TKA). Enhanced recovery after surgery (ERAS) protocols may reduce the VTE risk after these procedures. The aim of this study was to compare the risk of VTE and the risk of bleeding complications in a non-selected population of primary THA and TKA cases done within an ERAS protocol.

Fast track protocol for primary total hip arthroplasty in non-trauma cases reduces the length of hospital stay: Prospective French multicenter study.

Background: Fast-track (FT) procedures continue to evolve; however, their benefits are still controversial. This led us to conduct a prospective study of FT procedures for total hip arthroplasty (THA) on a national scale in France with historical control data. The aims were to (1) evaluate the effectiveness of FT procedures after THA on the length of hospital stay (LOS) in a multicenter analysis, (2) measure the immediate return to home, rehospitalization and reoperation rates.

Early experience with dual mobility acetabular systems featuring highly cross-linked polyethylene liners for primary hip arthroplasty in patients under fifty five years of age: an international multi-centre preliminary study.

Purpose: To evaluate early performance of contemporary dual mobility acetabular systems with second generation annealed highly cross-linked polyethylene for primary hip arthroplasty of patients under 55 years of age.

Methods: A prospective observational five years study across five centers in Europe and the USA of 321 patients with a mean age of 48.1 years was performed.

Are modern dual mobility cups a valuable option in reducing instability after primary hip arthroplasty, even in younger patients?

Hip instability after total hip replacement has been shown to be a critical cause of failure. The use of dual mobility has been classically restricted to patients "at risk", over 70 years of age. The question rises up about extended indications of so-called "modern" second generation dual mobility cups.
