Knee megaprosthesis: a salvage solution for severe open and complex distal femoral fracture associated with an ipsilateral brachial plexus injury (a case report with literature review)

open access: yesThe Pan African Medical Journal, 2015
Complex distal femoral fractures in the young patient often occur as a result of high velocity trauma. Timely recognition and treatment is everything in such a situation, and it needs a robust staged management pathway to optimize the chance of limb ...

Reimplantation of a Large Extruded Segment of Tibia in an Open Fracture in a Pediatric Patient

open access: yesThe Surgery Journal, 2019
A 6-year-old boy presented with a Gustilo type IIIB open fracture on his left leg with a segment of bone loss in his tibia. The boy's attendants brought two bone fragments recovered from the scene of the accident. The extruded bones were a segment with a

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

open access: yesAdvanced 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 ...

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

open access: yesAdvanced 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 ...

Negative-pressure wound therapy versus standard dressings for adults with an open lower limb fracture: the WOLLF RCT

open access: yesHealth Technology Assessment, 2018
Background: Open fractures of the lower limb occur when a broken bone penetrates the skin and is exposed to the outside environment. These are life-changing injuries. The risk of deep infection may be as high as 27%.

Validation of mangled extremity severity score in assessing the need for extremity amputation

open access: yesNigerian Journal of Medicine, 2017
INTRODUCTION: The decision to either salvage or amputate a mangled extremity poses great challenge to a surgeon.Different scoring systems were therefore developed to aid orthopaedic surgeons in this decision,eitherto contemplate amputation or proceed to ...

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

open access: yesAdvanced 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.

Open Radiocarpal Fracture Dislocation with Neurological Deficit Treated with Standalone External Fixation and Kirshner-Wires: Evaluation of Functional and Radiological Outcomes in a 4-Year Follow-Up: A Rare Case Report

open access: yesReports
Background and Clinical Significance: Radiocarpal fracture dislocations (RCFDs) are rare injuries of the wrist, while open RCFDs represent a small subgroup of these injuries. Limited data exists regarding the optimal method for their management.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...
