title: Coexistence of Extraskeletal Mesenchymal Chondrosarcoma and Isolated Hemihyperplasia: A Case Report.
abstract: BACKGROUND
  Arthroscopic fixation of tibial spine fracture without damage to the growth plate is very important in patients with open physis. The present article describes a simple and effective technique being used for the first time to treat this condition.
  
  
  METHODS
  A 16-year-old boy sustained avulsion fractures of tibial spine while playing. He was treated arthroscopically with excellent result.
  
  
  CONCLUSIONS
  Arthroscopic fixation of tibial spine fracture in patients with open physis with two cannulated screws perpendicular to each other is a very simple technique which provides strong construct, and allows early mobilization without risk of damage to the growth plate.
