Effect of Insertional Direction of Pedicle Screw on Screw Loosening: A Biomechanical Study on Synthetic Bone Vertebra under a Physiology‐like Load

Orthopaedic Surgery
Objectives It is now understood that pedicle screw loosening at the implant‐bone interface can lead to poor screw–bone interface purchase and decreased fixation stability. Previous biomechanical tests used cadaveric vertebrae and pull‐out or torque loads

Biologic gracilis augmentation with iliotibial band enhances recovery and lowers complications in ACL reconstruction compared with hamstring plus lateral tenodesis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the iliotibial band autograft biologically augmented with gracilis (ITBAG) technique with a hamstring tendon autograft combined with extra‐articular lateral tenodesis using fascia lata (HT‐LET), in terms of (1) return‐to‐sport rates, (2) patient‐reported functional outcomes and (3) complication rates.

From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

PLANTS, PEOPLE, PLANET, EarlyView.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...

Three‐Dimensional Scaffolds for Bone, Soft Tissue, and Periodontal Regeneration

Journal of Periodontal Research, EarlyView.
Three‐dimensional scaffolds offer tissue‐specific control of architecture, mechanics, porosity, and functionalisation to improve bone, soft tissue, and periodontal regeneration. ABSTRACT The oral cavity presents three distinct regenerative challenges: restoration of alveolar bone volume and stability, augmentation of soft mucogingival tissues, and ...

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet
