Virtual-reality simulation to assess performance in hip fracture surgery
BACKGROUND AND PURPOSE Internal fixation of hip fractures is a common and important procedure that orthopedic surgeons must master early in their career. Virtual-reality training could improve initial skills, and a simulation-based test would make it possible to ensure basic competency of junior surgeons before they proceed to supervised practice on patients. The aim of this study was to develo...
متن کاملLoad and strain during lateral condensation and vertical root fracture.
Vertical loads and root surface strains in extracted teeth during lateral condensation using finger and hand spreaders were measured and compared with loads and strains at fracture. Six groups each of 10 teeth were tested: maxillary central incisor, premolar and molar; and mandibular incisor, premolar and molar. Root strains were measured using strain gauges mounted on the apical and middle thi...
متن کاملDevelopment of a German fracture register to assess current fracture care and improve treatment quality
Continuous evaluation of current treatment methods is crucial in orthopaedic trauma surgery.Existing fracture registries substantially contribute to improving fracture care and quality of life in trauma patients.Currently there is no universal German fracture register recording the patient-centred outcome of non-surgical as well as surgical fracture treatment in all anatomical regions.Conclusio...
متن کاملStatistical fracture modeling: crack path and fracture criteria with application to homogeneous and functionally graded materials
Analysis has been performed on fracture initiation near a crack in a brittle material with strength described by Weibull statistics. This nonlocal fracture model allows for a direct correlation between near crack-tip stresses and failure. Predictions are made for both the toughness and average fracture initiation angle of a crack under mixed-mode loading. This is pertinent for composites and is...
