EXTRAARTICULAR TRIPLANE FRACTURE OF THE DISTAL TIBIA - A CASE-REPORT

The triplane fracture of the distal tibia is anatomically complex. It typically consists of a coronal fracture of the metaphysis, a transver se fracture of the physis, and a sagittal, intra-articular fracture of the epiphysis. We report an unusual variation of the triplane fractur e which includes an extra-articular epiphyseal component involving the medial malleolus. This is an important variant to recognize because i t does not disrupt the distal tibial articular surface. This lack of a rticular involvement allows for non-surgical management in contrast to the usual triplane fracture which often requires open reduction and i nternal fixation.
