Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

In larger, translational animal models, manual measurements of longitudinal bone growth using fluorochrome labels is tedious and may be prone to less rigor due to variations in reader experience, sampling differences, and photobleaching that limits the repeatability of measurements. This study assesses the reliability of three different digital methods to assist in measurement of distance between pulsed fluorochrome labels. Forty-five tibial physes from skeletally immature New Zealand White rabbits were pulsed with fluorochrome labels and measured using Fully Manual Technique (FMT), Manual Digital Measurement (MDM), Computer Assisted Image Processing (AIP), and Fully Automated Measurement (FAM).

Background: Many patients with a lower limb socket-suspended prothesis experience socket-related problems, such as pain, chronic skin conditions, and mechanical problems, and as a result, health-related quality of life (HRQoL) is often negatively affected. A bone-anchored prosthesis can overcome these problems and improve HRQoL, but these prostheses have potential downsides as well. A valid and reliable tool to assess potential candidates for surgery concerning a favorable risk-benefit ratio between potential complications related to bone-anchored prostheses and improvements in HRQoL is not available yet.

Department of Orthopaedics, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical Universit, Guangzhou, China.
Objective: The aim of this study is to assess the kinematic changes in the knee joint during walking in patients with isolated PCL-deficiency (PCLD) to determine the presence of walking-related joint instability (mechanical instability-abnormal displacement form structural damage). Additionally, the study seeks to provide biomechanical insights into the observed differences between subjective and objective assessments.
Methods: 35 healthy volunteers and 27 patients with isolated PCLD (both involved and uninvolved sides) were included in the study.
Revisiting two thousand hinge fractures in open wedge high tibial osteotomy with a fifty years review: the oscillating saw cannot replace the traditional "ear-hand" dialogue between osteotome and hammer to estimate the elastic modulus of bone.

Hospital Henri Mondor, University Paris East (UPEC), Avenue du Marechal de Lattre de Tassigny, 94000 Creteil, France.
Background: Hinge fracture on the lateral part of the tibia (LHF) is a common complication of medial Open Wedge High Tibial Osteotomy (OWHTO). Many factors have been described as risks for these fractures, but no study has compared an osteotome or an oscillating saw to prevent LHF following OWHTO.
Methods: This "propensity-score-matched" (PSM) study was conducted from data obtained in the literature from 1974 to November 2024.
