I am a paddler, and last Tuesday I was demoing a racing kayak and promptly flipped it upside down. When I reached the shore, I twisted my foot on a rock I didn’t see. This mishap lead to the following discussion of what attributes a canoe shoe and orthotic should have.

While I have only been in practice since 2008, patients are already returning for replacement devices. Most of these patients are children and some are adults.

When I dispense orthotics to patients I review things to look, or feel, for as the device ages such as: return of symptoms, callusing, pain, or a cracked device.

A patient presented with lateral column pain and the initial evaluation was a cavus foot with rearfoot varus. After utilizing the Coleman Block Test, it revealed that the hindfoot reduced nicely bilaterally to (and slightly beyond) perpendicular. Looking at the forefoot, the 1st metatarsal was rigidly plantarflexed below the transverse plane where the lesser met heads all rested.

The goal in selecting the orthotic prescription was to hold the foot neutral, and then bring the ground up to the lesser met heads. I used a poly shell with an EVA rearfoot post for shock absorption. To accommodate the plantarflexed 1st metatarsal, I added a Korex reverse Morton's extension and a topcover to finish up. Sometimes I back fill the region below the 1st met head with poron for additional padding.

I perform quite a few orthotic modifications each day in the office. These are on over-the-counter orthotics, poorly controlling custom devices, and minor adjustments to otherwise good devices. Sometimes the modification will really change how the foot functions on the orthotic. 

Patients often prefer that I don't significantly change their device, so I started using adhesive felt (1/8" and 1/4" thickness) to perform modifications and give patients a taste of what needs to be done. This allows me to modify the orthotic but still give the patient the opportunity to remove it (carefully un-peel it) if they can't tolerate it.

A patient with persistent forefoot callusing presented today for debridement.

I never thought I would place a full-length valgus wedge on a patient's orthotics.

I see a lot of workers comp cases and presently see a roofer. After about 2-3 hours on the roof he feels pain. In a stance exam of this patient, he is bow legged b/l with pronounced tibial varum and his RCSP is nearly perpendicular to the ground. Initially, he presented with typical plantar fasciitis symptoms and we tried a 0/0 motion rearfoot posted functional foot orthotic, neutral device with no inversion. This seemed to help the arch, but the patient slowly developed peroneal pain. In my initial attempt to relieve this, I added a reverse Morton's extension of cork to the devices that the patient enjoyed; then he increased time on the roof and this was proving to not help. So, I ...
