How To Overcome Obstacles With Custom Orthoses

Dr. Fritz says if a problem is significant enough to require an orthosis, it is worthwhile to reevaluate the orthosis a year later. He uses one year as a follow-up time since he feels orthotic labs should generally guarantee their work for at least a year. At the follow-up visit, he evaluates the patient, the problem and the orthotic, which may have some changes due to wear. Dr. Fritz says DPMs may address orthotic changes or repairs during the follow-up, noting that patients often request a new orthotic during that visit.    “Most patients in my experience would rather proceed and have a second pair of orthotics fabricated rather than give up their old orthotics for repairs even though it may only be for one week,” says Dr. Fritz. “People appreciate the benefits of their orthotic devices and are rarely willing to part with them even for a short period of time.”    The clinical symptoms of the patient will usually indicate whether one needs to evaluate the orthotics for refurbishing or replacement, according to Dr. Warkala. Often, he says one can easily replace the heel post to help reduce the patient’s discomfort, adding that the podiatrist should place the orthotic against the foot to ensure adequate contouring.    The lifespan of orthotic devices varies, says Dr. Levine, noting some patients require replacement of devices more often than others. As he points out, some patients will present with orthotic devices that are over 15 years old and they are still holding up well. He advises comparing the positive casts (which one can dispense with the orthotic devices) to the orthotic devices themselves. If the orthotic device no longer conforms to the cast, Dr. Levine says the shape of the orthosis may have changed enough to require fabrication of new devices. If new biomechanical complaints arise, he notes this may also warrant making new orthotic devices.    Dr. Fritz reminds that patients often keep old orthotics as back-up devices that they use sometimes for less demanding activities. He notes patients do choose additional orthotics.    “I believe in this day and age people are engaged in many activities and they often have many shoe styles,” says Dr. Fritz. “No one orthotic is perfect for all activities and all shoe styles.”    In addition, having two or three types of orthotics increases the spectrum of shoes that an individual can wear. As Dr. Fritz mentions, acrylics and graphites are sleek enough to fit in almost any shoe while patients may sometimes reserve full-length composites for heavy duty working environments as well as various sports.    Dr. Fritz’s discussions with patients do not center around the functionality of one device. He emphasizes increasing the range and use of orthoses as opposed to replacement. Dr. Fritz says clinicians should avoiding replacing something that works and encourage patients to upgrade and expand into a new orthotic that may better address a specific need in regard to activity or shoe fashion.    Dr. Fritz notes his children have sports orthotics for basketball as well as orthoses that work well with school shoes. “I have given them options and, in return, they have given me an education and insight into pros and cons associated with different devices,” notes Dr. Fritz.    

Q:

How does a shoe affect the function of an orthotic device?
