Physeal Arrest
  • Bone bridge obliterates the growth plate cartilage & prevents growth;
  • Peripheral bone bridges predispose the patient to angular deformities;
  • Most common sites of growth arrest include the distal tibia, distal humerus and distal ulnar physis;
  • Much less common sites include the distal radius and proximal humerus.

Radiology:

  • Extent of bone bridge is demonstrated by CT scanning and tomograms.

Indications for Bone Bridge Resection:

  • Resection is indicated if less than 1/3 to 1/2 of the growth plate is involved;
  • Younger children tend to have a better prognosis with resection than older children;
  • Less than 2 years of remaining growth is a relative contra-indication for bone bridge resection;
  • Central bars are more amenable to resection than peripheral bars;
  • Ischemic or septic related bone bars have a poor prognosis with resection.
