Dynamic compression nail: A preliminary report

BMC Musculoskeletal Disorders, 2001
Background Interlocking nailing, which has become the method of choice for treating fractures of the femoral and tibial shafts, still lacks ability to provide the important contact-compression at the fracture.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Coupling simulation of multistage pulse conflagration compression fracturing

Petroleum Exploration and Development, 2014
Due to the transient and multi-field coupling complexity of the multistage pulse conflagration compression fracturing, the coupling solution method for it was established, and the simulation calculation and field application analysis was conducted.

Open Reduction and Intrafragmentary Compression Fixation with External Fixator (the Ichi-Fixator) Treatment of Distal Phalangeal Nonunion

Case Reports in Orthopedics, 2020
The nonunion of distal phalangeal communized fracture is relatively rare in hand fractures. However, if it occurred, the surgical treatment is quite difficult because of small piece of fragmentations.

Trabecular structural difference between the superior and inferior regions of the vertebral body: a cadaveric and clinical study

Frontiers in Endocrinology, 2023
BackgroundOsteoporotic vertebral compression fractures commonly involve the superior vertebral body; however, their associated causes have not yet been clearly established.

A biomechanical study of headless compression screws versus a locking plate in radial head fracture fixation

, 2019
Hypothesis: Fixation of a 3-part radial head fracture with cannulated compression screws will show equivalent stiffness to a locking plate under axial load. Debate exists regarding the management of Mason type III fractures, with many believing that open

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Vertebroplasty for Vertebral Compression Fracture

Collegium antropologicum, 2009
The patients with intensive pain caused by the vertebra body fracture were treated by application of bone cement under local or general anesthesia, by means of diascopy through unilateral transpedicular approach. The intensity of pain was followed-up on the VAS scale before surgery, 24 hours after surgery and three months after surgery.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

Advanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.
