Early humans and the balance of power: Homo habilis as prey

open access: yesAnnals of the New York Academy of Sciences, Volume 1553, Issue 1, Page 140-157, November 2025.
The traditional view regarding Homo habilis as the primary agent in stone‐tool making and animal butchery has long shaped our understanding of human evolution. Recent advances in artificial intelligence (AI) methods have provided unprecedented insights into carnivore–hominin interactions through the analysis of bone surface modifications (BSMs).

Degradation of Abandonment Cement Plugs Under Prolonged Exposure to Completion Fluids: A Multi‐Technique Evaluation

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
Cement plugs used in oil well abandonment may degrade over time when exposed to completion fluids. This study shows a significant loss of compressive strength after 180 days, along with mineralogical changes like hydrocalumite formation. These findings highlight the importance of long‐term monitoring to ensure the safety and integrity of permanently ...

Dermal Allograft Reconstruction of the Superior Acromioclavicular Capsuloligamentous Complex With Knotless Suture Anchors

open access: yesArthroscopy Techniques, Volume 14, Issue 9, September 2025.
Abstract Acromioclavicular (AC) joint instability can significantly impact the shoulder girdle, causing notable pain and impaired function. Surgical management traditionally focuses on reconstruction of the coracoclavicular ligaments, providing reduction and stability in the coronal plane.

Sonographic Anatomy and Imaging of the Triangular Fibrocartilage Complex and the Distal Radio‐Ulnar Joint

open access: yesAustralasian Journal of Ultrasound in Medicine, Volume 28, Issue 3, August 2025.
ABSTRACT Introduction Ulnar‐sided wrist pain is a common clinical problem, which can be difficult to diagnose, manage and treat. Ultrasound imaging can be used to identify structural changes which may contribute to the pain. Knowledge of the associated relative anatomy and intertwining structures which form the triangular fibrocartilage complex (TFCC ...

Sonographic Anatomy and Imaging of the Dorsal Thumb Tendons

open access: yesSonography, Volume 12, Issue 2, Page 215-225, June 2025.
ABSTRACT Injuries to the dorsal thumb tendons and related structures can result in impairment to thumb motion. Ultrasound imaging is useful in diagnosing structural change in the dorsal thumb tendons, branches of the superficial radial nerve, and the dorsal hood.

Acromioclavicular Joint Repair and Reconstruction With a Tensionable Cerclage System Using a Single Clavicular Drill Hole

open access: yesArthroscopy Techniques, Volume 14, Issue 6, June 2025.
Abstract Acromioclavicular (AC) joint injuries occur with an incidence of 9.2 per 1,000 person‐years. There are a variety of indicated surgical techniques, with no clear superior method. The use of suspensory fixation with cortical buttons has increased in popularity.
