Bennett’s Fracture: two-part intra-articular fracture.

Rolondo Fracture: comminuted (at least three-part) Intra-articular fracture.

For Bennett’s fracture use the “screw-home-torque” technique or “revving a motorcycle” (thumb traction, palmar abduction and a pronation/radial rotation maneuver) technique for reduction.

Long term outcomes generally improved with surgical treatment.

Robert’s View X-ray (true thumb AP) is recommended to evaluate for fracture dislocation.
