Treatment of Bennett, Rolando, and vertical intraarticular trapezial fractures.

Intraarticular fractures at the first trapeziometacarpal joint include Bennett, Rolando, and vertical intraarticular fractures of the trapezium. If these fractures heal in a displaced position, a traumatic arthritis quickly develops at the thumb base. Open reduction and lag screw rigid internal fixation of a Bennett fracture is advisable if a satisfactory closed reduction cannot be obtained. If the palmar and dorsal displaced fragments of a Rolando fracture are of adequate size, an open reduction internal fixation may be performed with small lag screws incorporated through a T- or L-shaped buttress plate. A displaced vertical intraarticular fracture of the trapezium may be easily misdiagnosed as a trivial chip fracture, unless specific radiographic views are obtained. Open reduction internal fixation is the only treatment method that will provide a satisfactory outcome for this fracture.
