- bipartite patella
- pediatric avulsion fractures
- patellar dislocation
- 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
