- Discussion:
- bone bridge obliterates
growth-plate cartilage & prevents growth;
- peripheral bone bridges predispose patient to angular deformities;
- 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 growth plate is involved;
- younger children tend to have a better prognosis w/ 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 w/ resection;
- Technical Pearls:
-
surgery on growth plates
- interposition of fat is easiest and most commonly used agent to prevent bone bridge formation (alternatives
include silastic, methyl methacrylate, or free epiphysis);
