The dorsal ridge and volar waist need prudent assessment, especially in waist fractures.ĭestot E. ![]() Our study is the first to describe acute fracture morphology using 3D CT and to correlate comminution and displacement to fracture types. Comminution was located along the dorsal ridge and the volar scaphoid waist. Waist fractures had higher rates of comminution and displacement when compared with all other fractures. A total of 73% of displaced fractures had concomitant comminution. Most fractures were comminuted (52%) or displaced (64%). Most studies were in male patients (89%). The median delay from injury to CT was 29 days. Following virtual fracture reduction, fractures were mapped onto a three-dimensional scaphoid model. CTs were segmented and converted into three-dimensional models. CT scans of scaphoid fractures less than 6 weeks from time of injury were included in this retrospective, multicentre study. Materials and methodsĪ retrospective, multicentre database search was performed to identify CT studies of acute and subacute scaphoid fractures. The aims were to describe fracture morphology, to map fractures onto a 3D scaphoid model and to correlate this to scaphoid anatomy. ![]() Acute and subacute scaphoid fractures were assessed using 3D computer tomography (CT). ![]()
