Gait Example: Rearfoot & Tibial Varus Patient pronates at the Sub-Talar Joint (STJ) during loading response to compensate (adapt) for a Rearfoot (Calcaneal) Varus and Tibial Varus. Mid-Tarsal Joint is compromised by continued STJ pronated position into and through mid-stance, causing inversion at Longitudinal Mid-Tarsal Joint Axis (LMJA) resulting in medial arch collapse. Orthotic Intervention: Use semi-rigid or stiffer shell such as Proformer or Supporter, Deep Heel Seat to increase compression of heel pad. Post Rearfoot aggressively, with at least a four degree post and consider Heel Skive on positive cast. Extend Forefoot Wedge to Sulcus of at least two degrees . Top cover with materials appropriate for activity level. |

Gait Example: FF Equinus Patient pronates normally at the Sub-Talar Joint (STJ) during loading response, but continues to pronate late into mid-stance to compensate (adapt) for FF Equinus, attemptig to keep the heel on the ground. Mid-Tarsal Joint is compromised by continued STJ pronated position into and through mid-stance, causing collapse (motion) at Oblique Mid-Tarsal Joint Axis (OMJA) resulting in forefoot abduction and moderate “too may toes sign” at heel off. Orthotic Intervention: Use semi-rigid shell such as P.B.O. or Pro-Flex, Deep Heel Seat to increase compression of heel pad and elevate calcaneus. Post Rearfoot at moderate angle, with two or three degree post and incorporate Medial Arch Platform (MAP) on positive cast to allow for navicular drift medially. Add 1/8” heel lift bi-lateral to eliminate the need for STJ to pronate late. Top cover with materials appropriate for activity level.Learn more |
