Abstract
INTRODUCTION: The physeal fractures represent the 20-30% of all fractures of the child. The distal tibial physis is the third most frequently injured. The most important complication is the premature physeal closure (PPC). Aim of this study is to evaluate risk factors that can influence the outcome like fracture pattern, fracture displacement, mechanism of injury and treatment method. MATERIAL AND METHODS: The records of 46 patients treated for distal tibia physeal fractures between 2003 and 2013 were reviewed. Initial injury radiographs were categorized according to Salter-Harris and Dias-Tachdjian classifications and the initial and post-treatment fracture displacementwas measured. Any complex fractures had preoperative CT for additional assessment. Three different types of treatment were compared: closed reduction and casting versus closed reduction and percutaneous pinning versus ORIF. RESULTS: Therewas significantly less residual displacement in patients who had ORIF versus those who had closed reduction and percutaneous Kirschner wires or plaster only. In fractures with an intact fibula, we found significantly less initial and residual displacement. The Dias-Tachdjian classification is significantly correlated with the displacement. Patients studied with CT show a less degree of post reduction displacement. At the final follow-up we found only one PPC as complication. CONCLUSION: The physeal fractures are very common in children and the main goal is to avoid any complications. It is clear that the development of complications after distal tibial fractures is due to multiple contributing factors like skeletal maturity, severity of injury, fracture type, degree of comminution and displacement aswell as adequacy of reduction. A premature physeal closure is the most common complication. The fibula fracture can play an important role in initial displacement. The presence of an intact fibula and a good anatomical reduction have a significant positive influence on fracture outcome.
