Normal kinematics of carpal bones: A three-dimensional analysis of carpal bone motion relative to the radius

open access: yesJournal of Biomechanics, 1997
Normal carpal kinematics were studied in 22 cadaver specimens using a biplanar radiography method. The kinematics of the trapezium, capitate, hamate, scaphoid, lunate, and triquetrum were determined during wrist motion in sagittal and coronal planes. The

Morphofunctional examination of the carpal bones of pygmy hippopotamus from Ayia Napa, Cyprus

open access: yesAnatomical Record, 2022
This study provides a complete morphological description and functional analysis of the carpal bones of the endemic pygmy hippopotamus Phanourios minor, derived from the Upper Pleistocene site of Ayia Napa. From this deposit, numerous skeletal remains of

Inferring 3D Kinematics of Carpal Bones from Single View Fluoroscopic Sequences

open access: yesLecture Notes in Computer Science, 2011
We present a novel framework for inferring 3D carpal bone kinematics and bone shapes from a single view fluoroscopic sequence. A hybrid statistical model representing both the kinematics and shape variation of the carpal bones is built, based on a number

Quantitativein vivoanalysis of the kinematics of carpal bones from three-dimensional CT images using a deformable surface model and a three-dimensional matching technique [PDF]

open access: yesMedical Physics, 2000
The purpose of this study was to obtain quantitative information of the relative displacements and rotations of the carpal bones during movement of the wrist. Axial helical CT scans were made of the wrists of 11 volunteers.

Carpal bone fracture not to be missed

Emergency Medicine Journal, 2021
A young patient presented to the emergency department after a fight in which he sustained an injury to his right hand by punching. On clinical examination, there were no lacerations; there was noticeable swelling on the ulnar side of the dorsum of the wrist and he was very tender just distal to the ulnar styloid process.

Carpal Bone Fractures

Orthopedic Clinics of North America, 2007
Carpal bone fractures make up a significant proportion of injuries to the wrist. The complex bone shape and articulations make diagnosis more difficult and missed injuries more common. This article reviews carpal bone fractures excluding the scaphoid.

AVASCULAR NECROSIS OF CARPAL BONES

Magnetic Resonance Imaging Clinics of North America, 1995
MR imaging is extremely well suited to detection of early phases of avascular necrosis, permitting diagnosis before collapse of the carpal bones has occurred. The sensitivity of this imaging modality allows differentiation of subtle changes in the bone marrow signal. This is used as criteria for a new stage classification of Kienböck's disease based on

The Hunchback Carpal Bone

The Journal of Bone & Joint Surgery, 1961
Recognition of an os styloideum may prevent the embarrassment of its being mistaken for a more serious entity, such as fracture or tumor. In symptomatic cases, surgical removal of the prominence may be done, although the reports as to the lasting value of this are conflicting.

Chondromyxoid Fibroma in a Carpal Bone

Clinical Orthopaedics and Related Research, 1984
An unusual lesion developed in the trapezoid of a 25-year-old man. The tumor had histologic features most consistent with a diagnosis of chondromyxoid fibroma and had not recurred four years after curettage and bone grafting.

Fractures of the Carpal Bones

Radiology, 1957
The experience of the average radiologist with fractures of the carpal bones is limited by the relative rarity of many of these injuries. The navicular fractures are most important and are relatively common. Other fractures are usually less significant, but the radiologist should be aware of their prognosis and the complications to be expected so that ...
