Background: We performed a retrospective case study of 28 consecutive severely displaced radial neck fractures (Judet types III and IV) in children treated with elastic stable intramedullary nailing using the Metaizeau technique.
Methods: We reviewed all preoperative radiographs and classified the injuries according to Judet. All patients were asked to return for later assessment. They underwent physical examination; radiographs were taken; and they were asked for subjective assessment. An evaluation of clinical results was performed using the Mayo Elbow Performance Score (MEPS).
Results: According to Judet classification there were 13 type III and 15 type IV fractures. Using the MEPS, excellent results were achieved in 23 cases (82%) and good results in 5 cases (18%). The average MEPS was 97 points. Five patients complained of mild pain. Three malunions were observed.
Conclusions: Elastic stable intramedullary nailing is a minimally invasive technique, allowing stable fixation and providing excellent to good outcomes with a low complication rate.
Level Of Evidence: We performed a retrospective level 4 study of case series.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.

Ankle push-off is important for efficient, human-like walking, and many prosthetic devices mimic push-off using motors or elastic elements. The knee is extended throughout the stance phase and begins to buckle just before push-off, with timing being crucial. However, the exact mechanisms behind this buckling are still unclear.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.
Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Shear Wave Elastography (SWE) is an imaging technique that detects shear waves generated by tissue excited by Acoustic Radiation Force (ARF), and characterizes the mechanical properties of soft tissue by analyzing the propagation velocity of shear wave. ARF induces a change in energy density through the nonlinear propagation of ultrasound waves, which drives the tissue to generate shear waves. However, the amplitude of shear waves generated by ARF is weak, and the shear waves are strongly attenuated in vivo.

Silicon germanium alloy materials have promising potential applications in the optoelectronic and photovoltaic industries due to their good electronic properties. However, due to the inherent brittleness of semiconductor materials, they are prone to rupturing under harsh working environments, such as high stress or high temperature. Here, we conducted a systematic search for silicon germanium alloy structures using a random sampling strategy, in combination with group theory and graph theory (RG), and 12 stable SiGe structures in 2-8 stacking orders were predicted.
