title: [Clinical application of computer navigation in physeal bridge resection in pediatric partial epiphyseal plate closure].
abstract: OBJECTIVE
  To report our experience of using image-guided computer navigation for bone bridge resection in children.
  
  
  METHODS
  Between August 2008 and March 2011 at our hospital, computed tomography (CT)-based navigation system for bone bridge resection was used in 42 children with lower extremity deformities due to partial physeal growth arrest. There were 26 males and 16 females with an average age of 9.8 (5.0-13.0) years.
  
  
  RESULTS
  Six patients were lost to follow-up. In other 36 patients, the average duration of radiographic and clinical follow-up was 25 (15-44) months. Among them, 13 were corrected to neutral while 15 had insufficient correction. The average correction angle of deformities was 14 (8-25) degrees.
  
  
  CONCLUSIONS
  The image-guided computer navigation system enhances the accuracy and safety of bone bridge resection in children.
