Comparison of Bicortical versus Unicortical Medial Malleolus Fixation.
J Am Podiatr Med Assoc
January 2025
*Department of Orthopedic Surgery, University of Pittsburgh Medical Center, Pittsburgh, PA.
Background: Ankle fractures continue to increase in incidence and severity in an older, more challenging geriatric population. Medial malleolus fixation with partially threaded cancellous 4.0-mm screws, a common fixation method, has been shown to fail due to pullout strength.

Managing periprosthetic femoral fractures is challenging, particularly in osteoporotic patients with fragile bones. Revision with a long stem is commonly considered but may fail to provide adequate fixation and stability in fragile bones. A novel approach using sandwiched strut allografts and controlled bone crushing with robust cable fixation can offer mechanical support and provide secondary stability to the loosened femoral stem and can be considered a treatment option for low-demand patients.

Medicina (Kaunas)
January 2025
Department of Orthopedic Surgery, Anam Hospital, Korea University College of Medicine, 73 Goryeodae-ro Seongbuk-gu, Seoul 02841, Republic of Korea.
Distal tibia fractures are high-energy injuries characterized by a mismatch between standard plate designs and the patient's specific anatomical bone structure, which can lead to severe soft tissue damage. Recent advancements have focused on the development of customized metal plates using three-dimensional (3D) printing technology. However, 3D-printed metal plates using titanium alloys have not incorporated a locking system due to the brittleness of these alloys.

January 2025
Department of Veterinary Medicine, Graduate School of Konkuk University, Seoul 05029, Republic of Korea.
This study compares the compression force of cortical screws used in lag fashion with partially threaded cannulated screws and fully threaded headless cannulated screws as fixation methods for humeral condylar fractures in dogs. Cadavers of eleven dogs weighing an average of 10.99 ± 2.

Foot Ankle Surg
January 2025
Department of Trauma and Orthopaedic Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.
Background: The medial malleolus is involved in up to 50 % of ankle fractures. When surgery is required, a thorough understanding of bone mass distribution within the distal tibia is crucial for selecting and positioning screws to ensure stable fixation. Despite its clinical significance, data on the bone mass distribution in the distal tibia remains limited.
