Risk factors for complications and readmission after total hip or knee replacement with ERAS.

Introduction: The impact of enhanced rehabilitation after surgery (ERAS) on treatment quality and safety has been little reported. The present study aimed to analyze rates of complications and readmission in the 3 months after total knee or hip replacement (TKR, THR) following an ERAS protocol, by stratifying patients according to surgery time.

Methods: A single-center multi-surgeon retrospective observational study was conducted on prospectively collected data.

Initial Examinations of the Diastereoselectivity and Chemoselectivity of Intramolecular Silyl Nitronate [3+2] Cycloadditions with Alkenyl/Alkynyl Nitroethers.

This study examined the chemoselectivity and diastereoselectivity of silyl nitronate alkenyn-nitroethers in Intramolecular Silyl Nitronate Cycloadditions (ISNCs) to produce isoxazole derivatives with interesting medicinal properties. These reactions resulted in the formation of either dihydrofuro[3,4-c]isoxazolines/isoxazolidines and/or alkynyl moieties attached to 2,5-dihydrofuryl carbonyls. This study also discerned the diastereoselectivities of the resulting cyclic adducts and compared them to previous findings.

What is the lower limb length discrepancy after arthroplasty for proximal femoral fracture? A prospective, multicenter observational study of 590 hips.

Introduction: Lower limb length discrepancy (LLD) following hip arthroplasty after proximal femoral fracture (PFFA) is little studied. The aim of this work was to answer the following questions: 1) What are the incidence and mean values ​​of LLD after PFFA? 2) What are the clinical consequences (tolerance) of LLD after PFFA? 3) Can we identify risk factors for LLD after PFFA? 4) Is there a significant difference in terms of LLD after PFFA to treat intra- versus extra-capsular fractures?

Hypothesis: LLD after proximal femoral fracture arthroplasty is rare but has good clinical tolerance, given the low functional demands of the patients.

Patients And Methods: This is a multicenter prospective observational cohort study (15 centers), including 590 patients, operated on for hip arthroplasty for proximal femur fracture between May 2022 and June 2023.

Uterine artery projection relative to anatomical bony landmarks in CT-angiographies.

Purpose: The aim was to find bony landmarks of the pelvis for the origins and routes of uterine arteries, hoping to improve speed and safety of embolization procedures (leiomyoma, post-partum bleedings…).

Methods: We carried out a study based on the analysis of CT-angiographies in arterial phases of whole-body scans. Two measurements were done per artery, one from the origin of uterine arteries to a first perpendicular line passing through the lowest part of the sacroiliac joint, another one from the beginning of the parametrial segment from a second parallel line passing by the acetabular roof.
