Brooker I: Definition, Uses, and Clinical Overview
Brooker I is the mildest grade in the Brooker classification for heterotopic ossification around the hip. It describes small “islands” of extra bone seen in the soft tissues near the hip joint on X-ray. It is most commonly used after hip surgery, especially total hip arthroplasty (hip replacement). It helps clinicians describe and track post-operative bone formation in a consistent way.
