Position-Dependent Stability of an Unconstrained Total Talar Replacement and Its Suture Reinforcement: A Human Cadaveric Weight-Bearing Computed Tomography Study

Total talar replacement (TTR) is a joint-preserving alternative to arthrodesis in end-stage talar collapse. However, excising the talus detaches its anchoring ligaments and capsule, and unconstrained prosthesis constructs are prone to malalignment and dislocation. Moreover, it re...

A Surgical Algorithm for Upper Cervical Trauma Based on the AO Spine Upper Cervical Injury Classification System

Study Design. Global cross-sectional survey Objective. To establish a surgical algorithm for upper cervical spine injuries using the AO Spine Upper Cervical Injury Classification (UCIC) system, defining operative thresholds using a novel proposed Upper Cervical AO-Spine Injury Sc...

Validation of the AO Spine Osteoporotic Fracture Classification—effect of geographical region on reliability and reproducibility

Regional differences affect the reliability of the AO Spine-DGOU Osteoporotic Fracture Classification. European participants showed the highest agreement. This study underscores the need for addressing regional factors to improve the system’s global clinical utility. To evaluate...
