What is the role of ultrasonography in the early diagnosis of scaphoid fractures?

European Journal of Radiology Open, 2021
Scaphoid fractures are the most prevalent type of carpal bone fractures. High-spatial-resolution sonography detects direct signs of scaphoid fractures such as scaphoid cortical disruption; nevertheless, indirect signs such as radiocarpal effusion and ...

Musculoskeletal radiologist-level performance by using deep learning for detection of scaphoid fractures on conventional multi-view radiographs of hand and wrist

European Radiology, 2022
Objectives To assess how an artificial intelligence (AI) algorithm performs against five experienced musculoskeletal radiologists in diagnosing scaphoid fractures and whether it aids their diagnosis on conventional multi-view radiographs.

The influence of partial union on the mechanical strength of scaphoid fractures: a finite element study

Journal of Hand Surgery (European Volume), 2023
Assessment of scaphoid fracture union on computed tomography scans is not currently standardized. We investigated the extent of scaphoid waist fracture union required to withstand physiological loads in a finite element model, based on a high-resolution ...

Development and Validation of a Deep Learning Model Using Convolutional Neural Networks to Identify Scaphoid Fractures in Radiographs

JAMA Network Open, 2021
Key Points Question Can deep convolutional neural networks (DCNNs) detect occult scaphoid fractures not visible to human observers? Findings In this diagnostic study of 11 838 scaphoid radiographs, the DCNN trained to distinguish scaphoid fractures from ...

Development and Validation of a Convolutional Neural Network for Automated Detection of Scaphoid Fractures on Conventional Radiographs.

Radiology: Artificial Intelligence, 2021
Purpose To compare the performance of a convolutional neural network (CNN) to that of 11 radiologists in detecting scaphoid bone fractures on conventional radiographs of the hand, wrist, and scaphoid. Materials and Methods At two hospitals (hospitals A

Diagnosis and Treatment of Scaphoid Waist Fractures: A Literature Review

Journal of Orthopedic and Spine Trauma, 2020
Scaphoid fracture can cause serious complications and its diagnosis and treatment approaches are still contentious. Tenderness of anatomical snuffbox (ASB), longitudinal compression (LC) of the thumb, and scaphoid tubercle (ST) tenderness are very ...

Assessment of the healing of conservatively-treated scaphoid fractures using HR-pQCT.

Bone, 2021
Improving the clinical outcome of scaphoid fractures may benefit from adequate monitoring of their healing in order to for example identify complications such as scaphoid nonunion at an early stage and to adjust the treatment strategy accordingly ...

Scaphoid Fracture Detection by Using Convolutional Neural Network

Diagnostics, 2022
Scaphoid fractures frequently appear in injury radiograph, but approximately 20% are occult. While there are few studies in the fracture detection of X-ray scaphoid images, their effectiveness is insignificant in detecting the scaphoid fractures ...

Scaphoid plating for recalcitrant scaphoid fractures: a systematic review

, 2021
We conducted a systematic review of scaphoid plating for recalcitrant scaphoid fractures using EMBASE, Pubmed, Cochrane and MEDLINE. Thirteen studies were included. Ninety-three per cent of cases reported were male with a mean age of 27 years. Bony union
