Ankles are ladder-and-curb injuries — every standing trade feeds them into the system, and the ratings turn on measured motion loss and what the hardware left behind. The money math from any WPI is fixed, computed here by the rating engine.
How ankle injuries are measured
The AMA Guides rate ankles (impairment number 17.07.04.00 for range of motion) from dorsiflexion/plantarflexion and hindfoot deficits, with arthritis and gait derangement rated by other methods when they fit better. Rough anchors: a healed fracture with modest stiffness runs mid-single digits WPI; significant combined loss reaches the teens. A fusion rates on the ankylosis tables (17.07.02.00) instead: set in the optimal neutral position it’s just 4% WPI (10% of the leg), with impairment added for each malposition, up to a 25% WPI ceiling.

Apportionment
Unapportioned that was 23% — $26,245. The finding removed $7,250; see how apportionment works.
What this table can’t tell you
An antalgic gait pulls in the knee, hip, and back — multiple parts usually combine on the CVC rather than add, wages below the maximum scale the dollars down, and settlements price the medical tail beyond any table.
