Disappearing Carpal Bones

Massive osteolysis: disappearing bones.

Fractures of the Carpal Bones Excluding

Carpal fractures excluding the scaphoid can cause morbidity that is disproportionate to their incidence because they are easily overlooked and are often harbingers of a wider wrist injury. Failure to recognize a more global injury pattern can result in undertreatment and permanent wrist dysfunction. Diagnosis requires a high index of suspicion, familiarity with carpal topography to guide the ph...

Adeshina Et Al.: Carpal Bones for Skeletal Maturity of Infants

We compare the utility of models of the structure of carpal bones in the hand for predicting skeletal maturity in infants (0 -7 yrs). Skeletal maturity assessment is important for diagnosing and monitoring growth disorders. Statistical models of bone shape and appearance have been shown to be useful for estimating skeletal maturity. In this work we investigate the effect of the choice of models...

Coordinate systems for the carpal bones of the wrist.

The eight small and complexly shaped carpal bones of the wrist articulate in six degrees of freedom with each other and to some extent with the radius and the metacarpals. With the increasing number and sophistication of studies of the carpus, a standardized definition for a coordinate system for each the carpal bones would aid in the reporting and comparison of findings. This paper presents a ...

Isolated dislocation of the carpal scaphoid without the presence of an associated fracture or dislocation of the carpal bones

Isolated scaphoid dislocations are extremely rare injuries and are commonly associated with significant ligamentous disruptions. A dorsiflexion-supination force upon the hand consists the commonest mechanism of injury. Different treatment options have been proposed for the management of this uncommon entity, ranging from conservative treatment with closed reduction and casting to a wide range o...
