Magnesium alloys present a compelling prospect for absorbable implant materials in orthopedic and trauma surgery. This study evaluates an ultra-high purity, lean magnesium-calcium alloy (X0), both with and without plasma electrolytic oxidation (PEO) surface modification, in comparison to a clinically utilized WE43 magnesium alloy. It is shown that the mechanical properties of X0 can be tuned to yield a high-strength material suitable for bone screws (with an ultimate tensile strength of 336 MPa) or a ductile material appropriate for intraoperatively deformable plates (with an elongation at fracture of 24 %).

- The study examines elderly patients (65+) with maxillofacial trauma who are on anticoagulation or antiplatelet therapy, focusing on demographic details, causes, and types of injuries.
- More than half of the 188 patients studied were over 80 years old, with falls being the leading cause of facial injuries, while cardiovascular conditions were prevalent in many of these patients.
- The findings indicate significant injury types, complications such as facial hematomas and intracerebral hemorrhages, and potential implications for emergency department care and costs.
Article Synopsis
- The study compared two designs of three-dimensional osteosynthesis plates used for treating mandibular angle fractures, focusing on healing effectiveness and complications.
- A total of 54 patients with 56 fractures were evaluated, comparing a thinner square plate (1.0 mm) to a thicker triangular plate (1.3 mm).
- Results indicated that the triangular plate led to longer surgeries and a higher rate of complications, suggesting that the square plate is more effective and safer for treatment.
The authors present a novel approach for addressing excessive condylar growth in individuals exhibiting asymmetric mandibular growth patterns.

Methods: We examined 46 patients who underwent ablative surgery and received fibula free flap reconstruction. The main focus was to assess the influence of intraoperative blood pressure fluctuations and the administration of inotropic drugs on complications, either related to the flap or systemic, serving as the primary endpoint.
