title: Operative treatment of unstable distal radial fractures.
abstract: The results of operative treatment of unstable distal radial fractures were evaluated in 46 patients according to the criteria of Steinmann and Spier. The overall results were excellent or good in 35 patients (76.1%) and fair in 11 patients (23.9%). There were no poor results. Intra-articular fractures with volar dislocation (Smith type II) and fractures with severe comminution (Sarmiento type IV) are unstable and require surgery. Special attention must be paid to the Sarmiento type-II fracture with severe comminution of the dorsal cortex, severe radial shortening (greater than 10 mm) and dorsal tilt (greater than 25 degrees). Although not intra-articular, this fracture type may also prove to be unstable. The treatment of a Smith type-II fracture is a volar buttress plate unless extended comminution is present. Then, and in all other unstable fracture types, external fixation should be employed. In cases with severe loss of the dorsal cortex, bone grafting may be indicated.
