About Lesson

Methodology

Our current scanning methodology recommendations are based upon our most up to date understanding of evidence based scanning guidelines described in the literature. We have distributed, built and supported various 3D scanning hardware over the past decade and have a good understanding of how scanners need to work for our clinicians to get the best possible outcomes with our lab.

Calibration

It’s important that your 3D scanner captures an accurate representation of the patients foot. Our scanners can be calibrated to a clinical anthropometric measure in a simple way so we can ensure correct scaling and accuracy.

Colour Scanning

With colour you can objectively request changes at the foot orthosis interface based on markings made directly on the patient’s foot. The subtalar joint axis location, the patient’s plantar fascia, metatarsal dome positioning, that tricky part of the foot that needs offloading… Think of the improvements that can be made to your clinical outcomes by making the simple switch to 3D colour scanning.

 

Non-weight Bearing Scans

We can accept scans from any scanning methodology and advocate for clinician choice, however anecdotal evidence seems to suggest our clients achieve superior clinical outcomes when the NWB foot is used as a starting point. McPoil (1989) also found that NWB capture was superior to SWB casting, as SWB methods led to the capture of an artificial varus in the forefoot. Luaghton (2002) also suggested that the NWB technique has the most validity.

 

Manipulated Foot Positioning

Our EVA orthoses are able to incorporate full length intrinsic forefoot corrections. The possibilities are so much greater with full length EVA. Manipulating the forefoot at the point of scanning can lead to a more optimal application of force at the foot orthosis interface. No lab techs subjectively correcting your scans, we want to empower you to have more control. Increasing first ray plantarflexion also increases the available 1st MPJ dorsiflexion (Roukis 1996).

Unlocked File Format

Many scanners are lab or software locked and purchasing one of these scanners is simply bad practice. It limits your choice and exposes your clinical decisions to confirmation bias. At Cad Cam Orthotics we never lock in our clients. We truly want what is best for your patients.
