Modified Eichenholtz classification for the foot and ankle

	Stage 0	Stage 1 Fragmentation or resolution phase	Stage 2 Coalescence or early healing phase	Stage 3 Reconstruction phase
Clinical	There is oedema and erythema with loss of paresthesia. Clinical instability is present	Oedema and erythema persist. Ligament hyperlaxity increases	Decrease in oedema and erythema	Absence of swelling. Foot more stable but deformed
Radiographic	usually normal	Osteopenia, periarticular fragmentation, fractures and/or subluxations	Resorption of bone debris, early fusion of fragments and sclerosis	Arthrosis, osteophytes, subchondral sclerosis and deformity
