A Bennett's fracture is characterized by a fracture at the base of the first metacarpal with what type of dislocation?
Understand the Problem
The question is asking for the specific type of dislocation that occurs in conjunction with a Bennett's fracture, which is a fracture at the base of the first metacarpal bone (thumb).
Answer
A Bennett's fracture involves a fracture at the base of the first metacarpal with dislocation or subluxation of the thumb metacarpal.
A Bennett's fracture is characterized by a fracture at the base of the first metacarpal with a dislocation or subluxation of the metacarpal bone out of its normal position in the joint at the base of the thumb.
Answer for screen readers
A Bennett's fracture is characterized by a fracture at the base of the first metacarpal with a dislocation or subluxation of the metacarpal bone out of its normal position in the joint at the base of the thumb.
More Information
A Bennett's fracture is an intra-articular fracture, meaning it extends into the joint. It is the most common type of fracture affecting the base of the thumb.
Tips
It is important to differentiate a bennet fracture from a rolando fracture which is also an intra-articular fracture at the base of the thumb but is comminuted ( broken into several pieces).
