Comparison of bioabsorbable screw versus metallic screw fixation for tibial tubercle fractures in adolescents: a retrospective cohort study.

Background: Displaced tibial tubercle (TT) fractures in adolescents are typically treated with open reduction and internal fixation. While metallic screw (MS) fixation provides strong stability, it often results in a high incidence of postoperative screw head protrusion or irritation, leading to additional removal surgery. Bioabsorbable screw (BS) fixation presents an alternative that may avoid these issues, though its stability has not yet been extensively documented in the literature.

Femoral shaft fractures in preschool children: external fixation and elastic intramedullary nail treatments in clinical practice.

Surgical intervention in preschoolers with femoral shaft fractures has increased due to the evolving lifestyle. This study aimed to analyze and compare the efficacy of elastic intramedullary nailing and external fixation in treating femoral shaft fractures in children aged 2-5. Ninety-nine pediatric patients were categorized into the external fixator (EF) and the elastic intramedullary nail (ESIN) group based on surgical techniques.

Extraction, characterization, antioxidation and anti-inflammatory activity of polysaccharides from based on different molecular weights.

polysaccharide has a wide range of biological activities. In this study, polysaccharides (BPs), BPs-1 (30 kDa) and BPs-2 (2000 kDa) with different molecular weights were isolated and prepared by ultrafiltration interception method. The structures of BPs, BPs-1 and BPs-2 were characterised by monosaccharide composition, GC-MS, Fourier transform infra-red spectroscopy and nuclear magnetic resonance.

External fixator versus elastic stable intramedullary nail for treatment of metaphyseal-diaphyseal junction fractures of the pediatric distal femur: a case-control study.

Background: Several methods have been used for the treatment of pediatric distal femoral fractures, such as elastic stable intramedullary nail (ESIN), external fixator (EF) and plate osteosynthesis, but there has been no consensus about the optimal method. The purpose of this study was to compare the clinical outcome between EF and ESIN techniques used in metaphyseal-diaphyseal junction (MDJ) fractures of the pediatric distal femur.

Methods: We retrospectively analyzed operatively treated MDJ fractures of pediatric distal femur between January 2015 and January 2022.

Conservative versus surgical treatment of Gartland type II supracondylar humeral fractures in children.

The purpose of the study was to compare the efficacy of conservative and surgical treatments for Gartland type II supracondylar humerus fractures in children. We assessed 142 patients with type II supracondylar humerus fractures treated in our hospital from February 2018 to February 2019. The patients were divided into two groups: initial conservative treatment (Group A) and initial surgical treatment (Group B).

Treatment of unstable pelvic fractures in children with an external fixator: Retrospective study of 56 patients.

Purpose: We retrospectively analyzed the data of patients who underwent external fixation treatment for unstable pelvic fractures and evaluated the clinical effects of this treatment and factors influencing pelvic function recovery.

Methods: The data of patients with unstable pelvic fractures treated with an external fixator between January 2006 and December 2018 were retrospectively analyzed. The analyzed parameters included demographic data, fracture healing, pelvic asymmetry, deformity index, and complications.

Elastic stable intramedullary nailing versus Kirschner wire in the treatment of pediatric metaphyseal-diaphyseal junction fractures of the distal radius: a case-control study.

Background: Several methods have been used for the treatment of pediatric distal radius fractures, such as the elastic stable intramedullary nail (ESIN), Kirschner wire (K-wire), and plate, but there has been no consensus about the optimum method. The purpose of this study was to compare ESIN and K-wire techniques used in metaphyseal-diaphyseal junction (MDJ) fractures of the pediatric distal radius.

Methods: The data of patients who were treated at a children's hospital affiliated with Shandong University between August 2018 and January 2022 were analyzed retrospectively.

Compression screw internal fixation versus non-weight-bearing cast immobilization for Jones fractures in children.

Background: Several methods have been used to treat pediatric Jones fractures, but there has been no consensus about the optimum method. The purposes of this study were to compare the clinical outcomes between compression screw and non-weight-bearing techniques used in pediatric Jones fractures and clarify the most suitable treatment option for this population.

Methods: Twenty-one patients who presented with Jones fractures between January 2015 and June 2021 were analyzed retrospectively.

External fixator as a safe method in the treatment of distal tibial fractures in children.

Objective: The objective of this study is to evaluate the functional and radiological results of external fixator application in the treatment of distal tibial metaphyseal diaphyseal junction (MDJ) fractures in children and to analyze differences between stable and unstable fractures.

Methods: Medical records of children with distal tibial MDJ fracture confirmed by imaging from January 2015 to November 2021 were retrospectively analyzed. Patients were divided into stable and unstable groups and parameters, including clinical and imaging data and Tornetta ankle score were compared.

Comparison of diagnosis and treatment of MSSA and MRSA osteomyelitis in children: a case-control study of 64 patients.

Background: We aimed to compare the clinical characteristics of acute osteomyelitis caused by methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) in children.

Methods: We retrospectively analyzed the data of 64 children treated between September 2017 and June 2021. Based on the bacterial culture results, they were divided into MRSA and MSSA infection groups.

Molecular Dynamics Simulation Analysis of Damage and Expansion Process of Nanoindentation Single-Crystal 3C-SiC Carbide Specimens at Different Temperature.

The molecular dynamics method was used to analyze the influence of simulated temperature on the damage expansion process of the 3C-SiC sample under nano-indentation loading in order to study the influence of temperature on the internal damage and expansion mechanism of the 3C-SiC single crystal sample further during the nano-indentation loading process. A simulation test platform for diamond indenter indentation was established. The process of stress and strain distribution, dislocation evolution, dislocation expansion and potential energy change were analyzed, combined with the radial distribution function and load displacement curve.
