Table 1 Modified Neer classification of radiologic results
Score | Classification | Description | Treatment |
|---|---|---|---|
I | Healed | Cyst filled with new bone, with or without small radiolucent area(s) < 1 cm in size | Not necessary |
II | Healed with defects | Radiolucent area(s) < 50 % of the diameter of the bone with enough cortical thickness to prevent fracture | Not necessary |
III | Persistent cyst | Radiolucent area > 50 % of the diameter of the bone and with a thin cortical rim; no increase of the size of the cyst | Continued restriction of activity, possible repeated treatment required |
IV | Recurrent or nonresponsive cyst | Cyst reappeared in a previously obliterated area or a radiolucent area has increased in size | Need for repeated treatment |
