Imaging of pediatric musculoskeletal trauma: Age-specific considerations and challenges

Figure 11  Another example of an avulsion fracture. This is a patellar sleeve avulsion fracture. There’s a bone fragment that has been avulsed off of the inferior pole of the patella. An acute force has been applied at the patellar tendon and as a result has avulsed a piece of the patella off. Note: The bony fragments often underestimate the degree of injury, and so a magnetic resonance imaging could be obtain to understand how much chondral injury there is.
