Hvordan er arkitekturen av metacarpene ved nøytral håndposisjon?
Architecture of the metacarpus
While in neutral position, the longitudinal axis of each finger is parallel, and the longitudinal axis of the abducted thumb and the spread fingers converge to an intersection point in the capitate.
The metacarpus is where the five digital rays form and then develop into the thumb and fingers.
Hvordan er håndens arkitektur ved flekterte fingre?
Architecture of the metacarpus
When bending the finger joints, the axes converge to an intersection point in the scaphoid.
The metacarpus is where the five digital rays form and then develop into the thumb and fingers.
Hvordan er distrubisjonen av scaphoidfrakturer?
Scaphoid fractures
Frequency and distribution of scaphoid fractures. Middle third scaphoid fracture is shown.
Carpal fractures, most notably scaphoid fractures (accounting for two thirds of all cases), are another injury caused by falling on the outstretched hand extended in the dorsal direction. Young people are predominantly affected by scaphoid fractures (typical sports injury).
