OAR 436-035-0190
Foot
(1)
Ankylosis at the tarsometatarsal joints receives a rating of 10% of the foot for each of the tarsometatarsal joints ankylosed.(2)
The following ratings are for loss of subtalar inversion in the foot: [Rating not included. See ED. NOTE.](3)
The following ratings are for subtalar inversion (varus) ankylosis in the foot: [Rating not included. See ED. NOTE.](4)
The following ratings are for loss of subtalar eversion in the foot: [Rating not included. See ED. NOTE.](5)
The following ratings are for subtalar eversion (valgus) ankylosis in the foot: [Rating not included. See ED. NOTE.](6)
The following ratings are for loss of dorsiflexion (extension) in the ankle joint: [Rating not included. See ED. NOTE.](7)
The following ratings are for dorsiflexion (extension) ankylosis in the ankle joint: [Rating not included. See ED. NOTE.](8)
The following ratings are for loss of plantar flexion in the ankle joint: [Rating not included. See ED. NOTE.](9)
The following ratings are for plantar flexion ankylosis in the ankle joint: [Rating not included. See ED. NOTE.](10)
The following applies when determining impairment for loss of motion or ankylosis in the ankle or subtalar joint:(a)
If there is loss of motion only (no ankylosis in either joint) in the subtalar joint or the ankle joint, the following applies:(A)
the values for loss of motion in the subtalar joint are added;(B)
the values for loss of motion in the ankle joint are added;(C)
the value for loss of motion in the subtalar joint is added to the value for loss of motion in the ankle joint.(b)
If there is ankylosis in the ankle or subtalar joint, the following applies:(A)
When there is ankylosis in one joint only with no loss of motion or ankylosis in the other joint, that ankylosis value is granted.(B)
When there is loss of motion in one joint and ankylosis in the other joint, add the ankylosis value to the value for loss of motion in the non-ankylosed joint.(C)
When the ankle joint is ankylosed in plantar flexion and dorsiflexion, use only the largest ankylosis value for rating the loss or only one of the values if they are identical. Under OAR 436-035-0011 (Determining Percent of Impairment)(10), this ankylosis value is granted in lieu of all other range of motion or ankylosis values for the ankle joint.(D)
When the subtalar joint is ankylosed in inversion and eversion, use only the largest ankylosis value for rating the loss or only one of the values if they are identical. Under OAR 436-035-0011 (Determining Percent of Impairment)(10), this ankylosis value is granted in lieu of all other range of motion or ankylosis values for the subtalar joint.(E)
When both joints are ankylosed, add the ankle joint value to the subtalar joint value.
