Rolando fracture

Rolando fracture is a three part or comminuted intra-articular fracture-dislocation of the base of thumb (proximal first metacarpal). It can be thought of as a comminuted Bennett fracture. 

The mechanism is usually an axial blow to a partially flexed metacarpal, such as a fistfight. The fracture line is typically T or Y-shaped. The volar fragment remains attached to the carpometacarpal joint, while the main dorsal fragment subluxes or dislocates dorsally and radially due to the unopposed pull of abductor pollicis longus.

This is an unstable injury that requires surgical reduction and fixation.

It is named after Silvio Rolando (Italian surgeon).
