Medial Flange
Function:
- Anti-Pronation Reaction & Posts
- Medial stabilization of 1st ray and calcaneus
- Adds rigidity and strength to frame
Clinical Indication:
- Extreme overpronation
- Severe pes planus
- Collapsed talonavicular joint
- Posterior tibial tendonitis

About:
A medial flange is a curved increase in the height of the frame superiorly on the medial side of the orthotic. It begins at the medial mid-calcaneus (distal rearfoot) and extends distally with the curvature increasing in height to the apex near the navicular tuberosity, and then decreasing in height to terminate along the first metatarsal shaft. The height of the flange can be modified at the practitioner’s discretion.
Note: This modification adds bulk to a device, so it is recommended a patient uses proper shoe gear to accommodate.

Phalanges, literally meaning "fingers", are used both medially and laterally on a CFO to provide more support.
Phalanges (aka Flanges) give you an incredible wall medial or lateral against the motions of pronation (medially), or supination (laterally). The exception to that general rule is that lateral phalanges can be a vital part of an orthosis trying to block forefoot abduction on the rear foot in a pronator with a high axis to their mid tarsal joint. You can visualize phalanges by placing your finger on the top of the medial and/or lateral sides of the orthosis running distal to the heel cup area.
I love to imagine very prescribing clinician having a solid understanding of 4 classical orthotic shapes at their disposal. You take your image (casting or scanning) and you then decide what you will order to help this patient. I will be going over and over this concept this next year. You should have your standard "A" orthotic device. This is your gold standard. "B" will provide more pronation control. "C" will be more super-charged than "B" in terms of pronation correction. It is "C" that will have some version of a medial flange, and if there is forefoot abduction that is excessive, also have a lateral phalange. This could be called a low-cut UCBL. "D" will be different from "A" in terms of more lateral support for supinators. All my "D" orthoses have a lateral flange. Therefore, lateral flanges are used more often. Flanges in general will fill up the room in shoes more, but athletic shoes in general with a removable insert accommodate them well.
