What two eponymous fractures in the same region describe intra-articular fracture?
Bennett fractures and Rolando fractures.
How do Bennett and Rolando fractures differ from each other?
A Bennett fracture is a two-part fracture intra-articular fracture (i.e one fracture fragment) whereas Rolando fractures are a three-part fracture, with the fracture line taking on a Y or T shape.
How are most epibasal fractures treated?
The majority of these fractures are stable and can be treated with a thumb spica.
What is the indication for operative (K-wire fixation) management?
For unstable fractures, fractures with more than 30 degrees of angulation and fractures involving the joint surfaces where there is more than 3 mm of displacement, open reduction and internal fixation (ORIF) is typically recommended.
A minimally displaced and non-angulated transverse fracture through the base of the first metacarpal bone is demonstrated without involvement of the articular surface.
