骨软骨损伤的分期(Osteochondral injury staging) – 影像PPT(精)

1999 年,Hepple等提出MRI的修正分期系统:

1期:仅有关节软骨损伤;

2a期:关节软骨损伤,伴有软骨下骨折和周围骨髓水肿;

2b期:关节软骨损伤,伴有软骨下骨折,无周围骨髓水肿;

3期:骨碎片分离,但无移位;

4期:骨碎片分离,有移位;

5期:关节软骨下囊肿形成。

 In 1999, Hepple et al devised the following staging system:

  • Stage 1 – Articular cartilage damage only

  • Stage 2 – Cartilage injury with underlying fracture

    • Stage 2a – Cartilage injury with underlying fracture and edema

    • Stage 2b – Cartilage injury with underlying fracture but no edema

  • Stage 3 – Detached (rim signal) but not displaced fragment

  • Stage 4 – Displaced fragment

  • Stage 5 – Subchondral cyst formation

目前最为广泛接受及使用的是Hepple分期系统。
