2024年1月2日 · Capitate fractures are an uncommon carpal fracture. They rarely occur in isolation and are often associated with greater arc injuries.
Carpal bone fractures | Radiology Reference Article
2022年4月21日 · Carpal bone fractures comprise a range of different fractures which carry varying outcomes. They can involve one or a combination of carpal bones and also be part of fracture-dislocations. Individual fractures (most to least common): scaphoid fracture: 50-80%; triquetral fracture: ~18%; trapezium fracture: ~3-5%; lunate fracture: 3.9%; capitate ...
Lunate fracture | Radiology Reference Article - Radiopaedia.org
2024年5月3日 · Lunate fractures are often secondary to axial loading of the capitate bone. This is seen in forceful hyperextension with ulnar deviation 2. Radiographic features. The lunate is made up of the volar pole, body, and dorsal pole. Volar pole fractures are more commonly observed as the lunate is compressed by the capitate.
Capitate | Radiology Reference Article | Radiopaedia.org
2023年3月30日 · The capitate, also known as the os magnum, is the largest of the carpal bones and sits at the center of the distal carpal row. A distinctive head-shaped bone, it has a protected position in the carpus, and thus isolated fractures are unusual.
Triquetral fracture | Radiology Reference Article - Radiopaedia.org
2023年10月9日 · Triquetral fractures are carpal bone fractures generally occurring on the dorsal surface of the triquetrum. The triquetral may be fractured by means of impingement from the ulnar styloid, shear forces, or avulsion from strong ligamentous attachments.
Perilunate dislocation | Radiology Reference Article
2023年2月6日 · Perilunate dislocations and perilunate fracture-dislocations are potentially devastating closed wrist injuries that are often missed on initial imaging. These injuries involve dislocation of the carpus relative to the lunate which remains in …

2024年7月13日 · The hamate articulates with five bones: the lunate, capitate, triquetral, fourth metacarpal, and fifth metacarpal: proximal thin margin of the wedge articulates with the lunate while the fourth and fifth metacarpals articulate with the base distally. medial surface is broad and articulates with the triquetrum. lateral surface articulates with ...
Distal radial fracture | Radiology Reference Article - Radiopaedia.org
2024年7月31日 · Distal radial fractures are a heterogeneous group of fractures that occur at the distal radius and are the dominant fracture type at the wrist. These common fractures, representing ~15% of all fractures 7 , usually occur when significant force is applied to the distal radial metaphysis.
Scaphoid fracture | Radiology Reference Article - Radiopaedia.org
2024年3月27日 · Scaphoid fractures account for 70-80% of all carpal bone fractures 1. Although they occur essentially at any age, adolescents and young adults are most commonly affected 1 . Older patients falling in a similar manner are more likely to sustain a distal radial fracture (usually a Colles fracture ).
