Posting
N.B. a note about ‘Post According to Lab’:
While you may ask our orthotic designers to ‘post according to lab’, and they will use their extensive knowledge of foot dynamics to accommodate your patient’s foot, please know that you are in the BEST position to determine the correct posting requirements for your patients. ‘Post According to Lab’ should rarely, if ever, be used. It is available as an option but we prefer that you instruct us as to your exact requirements.
Here is an overview of your posting options.
Rear Foot Posts
Intrinsic
Extrinsic
For direct milled poly shells, intrinsic posts will transect the plane directly under the heel as shown in the figure above
Direct milled poly shells can have either a DM milled extrinsic post, as shown above, or
an extrinsic EVA post as shown below.
For vacuum pressed poly shells, intrinsic posts will also transect the plane directly under the heel as shown in the figure below.
Vacuum pressed poly shells can have an extrinsic EVA post added as well.
For vacuum pressed EVA shells, intrinsic posts will look the same as extrinsic posts as we will retain a ‘flat’ bottom profile for the bottom surface of the orthotic as shown in the picture below.
Vacuum pressed EVA shells will have a ‘flat’ profile for the bottom surface, posted at the desired angle of course.
Fore Foot Posts
Intrinsic
Extrinsic
All extrinsic forefoot posts are made of EVA for all shell types.
Direct milled poly shells have their intrinsic forefoot posts in the orthotic design as shown above.
See above picture for a tip post on a direct milled poly shell.
Vacuum pressed poly shells have their intrinsic forefoot posts in the orthotic design and ground down from the plantar surface as shown below.
See the pictures below for extrinsic forefoot posts to sulcus on a vacuum pressed poly device
Vacuum pressed EVA shells have their intrinsic forefoot posts in the orthotic design as shown below.
and a Vacuum Pressed EVA shell, also to sulcus.
Skives
In Cast
When a skive has been ‘captured’ in the cast by the clinician, the orthotic designer does NOT alter the shape of the orthotic externally. Normal posting instructions are applied.
To find out how to manually ‘capture’ the skive directly in the cast, please see our video tutorial here.
Not in Cast
If the clinician has NOT ‘captured’ the skive manually in the cast, the orthotic designer will alter the shape of the heel to skive the orthotic design.
Inverted
RearFoot
The orthotic designer will slice the scan in half at the midpoint of the arch and rotate the REAR foot by the specified degrees.
ForeFoot
The orthotic designer will slice the scan in half at the midpoint of the arch and rotate the FORE foot by the specified degrees.
Wedges
Medial
Medial wedges are tapered from heel to toes unless otherwise specified in the notes section.
Lateral
Lateral wedges are tapered heel to toes unless otherwise specified in the notes section.
