Is ultrasound superior to fluoroscopy in distal radius volar fixation?

Objectives: In volar distal radius fixation, conventional and additional fluoroscopic views could not be sufficient to assess dorsal screw penetration. Ultrasound (US) has been suggested as a technique to improve this assessment. The objective was to determine the agreement between these two explorations in a clinical study.

A proposal of a new algorithm for decision-making approaches in open reduction and internal fixation of complex tibial plateau fractures - SOTA algorithm (Spanish Orthopaedic Trauma Association).

Introduction: The correct choice of surgical approaches in complex tibial plateau fractures is essential to achieve adequate reduction and fixation. Detailed fracture morphology and direction of columns displacement, that we have named the Main Deformity Direction (MDD), may aid in selecting the optimal surgical strategy. In this article we present a new algorithm based on MDD and column concepts.

Risk factors for infection in fixation of distal tibia fractures.

Background: The aim of this study is to evaluate risk factors for infection as well as infection rates after open reduction and internal fixation for distal tibia fractures with a distal tibia locking plate and/or isolated screws.

Methods: This is a retrospective and descriptive study based on 55 patients treated in our Major Trauma Centre from January 2009 to December 2016. All patients were classified by age, sex, open or closed fracture, injury mechanism, comorbidities, fixation and time from injury to surgery.

An intact fibula may contribute to allow early weight bearing in surgically treated tibial plateau fractures.

Purpose: The role of the proximal tibiofibular joint (PTFJ) in tibial plateau fractures is unknown. The purpose of this study was to assess, with finite-element (FE) calculations, differences in interfragmentary movement (IFM) in a split fracture of lateral tibial plateau, with and without intact fibula. It was hypothesized that an intact fibula could positively contribute to the mechanical stabilization of surgically reduced lateral tibial plateau fractures.

Fixation of a split fracture of the lateral tibial plateau with a locking screw plate instead of cannulated screws would allow early weight bearing: a computational exploration.

Purpose: To assess, with finite element (FE) calculations, whether immediate weight bearing would be possible after surgical stabilization either with cannulated screws or with a locking plate in a split fracture of the lateral tibial plateau (LTP).

Methods: A split fracture of the LTP was recreated in a FE model of a human tibia. A three-dimensional FE model geometry of a human femur-tibia system was obtained from the VAKHUM project database, and was built from CT images from a subject with normal bone morphologies and normal alignment.
