The Risk of Postoperative Periprosthetic Femoral Fracture After Total Hip Arthroplasty Depends More on Stem Design Than Cement Use: An Analysis of National Health Data from England.
J Bone Joint Surg Am
January 2025
Leeds Institute of Health Sciences, School of Medicine, University of Leeds, Leeds, West Yorkshire, England.
Background: In this study, we estimated the risk of surgically treated postoperative periprosthetic femoral fractures (POPFFs) associated with femoral implants frequently used for total hip arthroplasty (THA).
Methods: In this cohort study of patients who underwent primary THA in England between January 1, 2004, and December 31, 2020, POPFFs were identified from prospectively collected revision records and national hospital records. POPFF incidence rates, adjusting for potential confounders, were estimated for common stems.
Objective: Aim: Study the mechanism of interaction between the 'sacroiliac joint - screw' system and determine the optimal parameters of the stabilizing structure, the strength of the system connection through computer modeling, and anatomical-biomechanical experiment.
Patients And Methods: Materials and Methods: The optimal parameters of the stabilizing structure for the sacroiliac joint were calculated using software package MathCAD. To validate the results of the numerical modeling, corresponding investigations of mechanical characteristics and determination of stiffness of the studied systems were conducted by an upgraded testing stand, TIRAtest-2151.
Objective: Aim: To investigate the peculiarities of deviations of preoperative values of biochemical markers of inflammation in the blood serum of patients with degenerative diseases of the lumbar spine after transpedicular fixation, with a complicated postoperative course to predict the development of various postoperative complications.
Patients And Methods: Materials and Methods: The content of glycoproteins (GP), sialic acids (SA), C-reactive protein (CRP), seroglicoids (SG), haptoglobin (HG), Veltman`s test (VT) were investigated. The results are comparable by the Student-Fisher method.
Arthroscopically Assisted Reduction and Fixation of Acute Tillaux, Pilon, Bosworth, Talar, and Calcaneal Fractures: A Systematic Review.

†University Orthopaedic Surgery Department, Faculty of Medicine, Democritus University of Thrace, University General Hospital of Alexandroupolis, Alexandroupolis, Greece.
Increased use of arthroscopically assisted techniques for the treatment of ankle fractures has been reported. Despite their rapid development, there is only one systematic review regarding arthroscopically assisted treatment of ankle fractures, in which, however, only malleolar fracture studies are included. Various other types of ankle fractures have also been treated with arthroscopically assisted procedures.

‡Canakkale Onsekiz Mart University Medical Faculty, Department of Orthopedics and Traumatology, Çanakkale, Turkey.
Background: The aim of study was to biomechanically compare the fixation of Jones fracture using headless cannulated screw, tension band, and two Kirschner wires.
Methods: A total of 60 fourth-generation, fifth metatarsal synthetic bone models were divided into three groups according to the fixation techniques. A vertical load, oriented from plantar to dorsal and lateral to medial, was applied to the metatarsal specimen that were potted with molding material.
