Triplane fracture of the distal tibia.

A prospective study of 21 triplane fractures of the distal tibia is presented. Nineteen cases (90.5%) had lateral triplane fractures, while the other two (9.5%) had medial triplane fractures. Two fragment fractures were encountered in 12 cases (57%); three fragment fractures in six cases (29%), and four fragment fractures in the remaining three cases (14%). Fourteen cases (67%) were managed non-operatively, while in seven cases (33%), open reduction and internal fixation was performed. Twenty patients (95%) were pleased with the final outcome. Objectively, 14 cases (67%) achieved excellent results.
