To create medial and lateral stability. Ankle, subtalar, or midtarsal trauma. Talocalcaneal varus or valgus. Severe pronation, pes planus.
Some valgus position is well tolerated.
The ptt patient exceeds that envelope. In my opinion, the normal anatomical 5-8 degrees valgus can be ignored, and the heel reduced as far varus as possible, perhaps approximating zero degrees. The talus becomes a non entity, as it is hopelessly locked into and under the medial malleolus. Info Request Form Marketing Flyer Arizona AFO Post. After Charcot AZ AFO Correct Descrip.
