| Stage | Radiographic finding | Clinical finding | Proposed treatment |
| 0 (Prodromal) | Normal | Swelling, erythema, warmth | Patient education, serial radiographs, protected weightbearing |
| I (Development) | Osteopenic, fragmented, joint subluxation or dislocation | Swelling, erythema, warmth, ligamentous laxity | Protected weightbearing until radiographic resolution of fragmentation and presence of normal skin temperature (usually 2 to 4 months) |
| II (Coalescence) | Absorption of debris, sclerosis, fusion of larger fragments | Decreased warmth, decreased swelling, decreased erythema | Casting, prefabricated pneumatic brace, Charcot restraint orthotic walker, or clamshell ankle-foot orthosis (6 months to 1 year) |
| III (Reconstruction) | Consolidation of deformity, joint arthrosis, fibrous ankyloses, rounding and smoothing of bone fragments | Absence of warmth, absence of swelling, absence of erythema, stable joint ± fixed deformity | Plantigrade foot: Custom shoes Nonplantigrade foot/ulceration: Surgical reconstruction, deformity correction |
