Table 1 Modified Neer classification of radiological results
From: Minimal invasive surgery for unicameral bone cyst using demineralized bone matrix: a case series
Classification | Description |
|---|---|
Healed | Cyst filled by new bone, with or without small radiolucent area(s) < 1 cm in size |
Healing with defects | Radiolucent area(s) < 50% of the diameter of bone, with enough cortical thickness to prevent fracture |
Persistent cyst | Radiolucent area > 50% of diameter of the bone and with a thin cortical rim. No increase in the size of the cyst. Continued restriction of activity or repeated treatment is required |
Recurrent cyst | Cyst reappeared in a previously obliterated area, or a residual radiolucent area has increased in size |
