The triplane fracture has been described as a fracture of the distal tibial epiphysis occurring across three planes-sagittal, transverse and coronal. The characteristic pattern of fusion of distal tibial epiphysis explains the special configuration of the fragments in the triplane fracture. According to Dias-Tachdjian classification, triplane fracture is classified two part fracture, three part fracture, four part fracture and two part fracture with extension to the medial malleolus. Among four types, two part triplane fracture with extension to the medial malleolus is a relatively rare injury and generally is not treated by closed reduction. Such fractures should have an anatomic reduction and adequate fixation to restore the joint congruity and obtain an anatomic reduction of the growth plate to prevent a future growth deformity. This is usually best accomplished with an open reduction and screw fixation or k-wire fixation. We experienced two part triplane fracture with extension to medial malleolus and check the CT to define the extent of the injury completely. And then we underwent open reduction and screw fixation for the fracture. As a result, we present four cases of two part triplane fracture with extension with review of related literatures.

Purpose: To evaluate the result of percutaneous fixation with cannulated screws and Ilizarov external fixator in triplane fracture of the distal tibial epiphysis in children. Materials and Methods: Between May 2004 and December 2007, 14 cases with triplane fractures were treated by percutaneous fixation with cannulated screws and Ilizarov external fixator after underwent CT imaging to assess the fracture pattern, articular disruption and to plan further management. Mean age and follow-up period were 14.1 years old and 15 months respectively. Results: There were satisfactory results in all 14 cases that had excellent reduction and stable fixation. All cases regained full range of movement within 6 weeks. Conclusion: We obtained satisfactory result after percutaneous fixation with cannulated screws and Ilizarov external fixator in triplane fractures of the distal tibial epiphysis in children.

A checkrein deformity can occur after a distal tibiofibular fracture. Usually, a checkrein deformity due to a dysfunction of the extensor hallucis longus muscle is rarer than that of the flexor hallucis longus. Only a few related studies have been reported. The authors encountered an extensor hallucis longus checkrein deformity due to extensor retinaculum syndrome while managing a triplane fracture. In magnetic resonance imaging, an increase in the heterogeneous signal was observed on the T2-weighted images suggesting muscle necrosis or ischemic changes in a part of the extensor hallucis muscle. Postoperative great toe motor weakness, unintentional movement, sensory changes, and weakness improved spontaneously during the follow-up.
