Rare Isolated Trapezium Fracture: Clinical Case Presentation

open access: yesGazeta Médica, 2022
Isolated trapezium fractures are rare, accounting for 0.4% of the hand injuries. As these injuries are often imperceptible on plain radiographs, diagnosis in the Emergency Department setting is challenging. Computed tomography scan can be helpful in the

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

open access: yesEuropean 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 ...

Correlation Between the Entry Point for Volar Percutaneous Scaphoid Fixation and Fracture Line [PDF]

open access: yesMinia Journal of Medical Research, 2020
Introduction: The word scaphoid is derived from the Greek word (skaphos) for boat. Because of its unique anatomy it can articulate with all five surrounding bones (distal radius, os capitatum, os lunatum, os trapezium and os trapezoideum)(1).

Arthroscopic Assisted Treatment of Combined Trapezium and Bennett Fracture-Dislocation

open access: yes, 2023
: Trapezium fractures are unusual; however, they represent the third most frequent fracture of the carpal bones. As they usually follow a high-energy trauma, they are associated with distal radius, Bennett, or Rolando fractures in 80% of cases ...
