pediatric avulsion fractures

patellar dislocation
- Discussion:
- are primarily of two types;
- direct blow, or more commonly patellar dislocation, may cause an
immediate frx around the point of contact, separating a single
fragment that includes articular cartilage, subchondral bone, and
supporting trabecular bone.
- this piece may never displace, and in this case fracture usually heals
with time and causes little trouble;
- however, fragment may displace and become a mechanically troublesome loose body;
- excision has been recommended in these situations but, for large fragments,
stabilization by transosseous fixation with Herbert screw has been described.
