Frequently asked questions

Some search terms you can use include the following: "closed fracture displaced," "closed fracture nondisplaced," "physeal fracture of upper end," "physeal fracture of lower end," and "pathological fracture, right fibula, initial encounter," just to mention a few. Please make sure you're clear that it's for the knee to better narrow your search on ICD databases.

It depends on whether it requires some adjustments/add-ons. It could take up to an hour.

If the orthosis isn't fitted properly, it might cause discomfort that lasts beyond the adjustment period. It may even cause circulatory problems if it's too tight. Prolonged use of it might lead to skin irritations and pressure sores. This is rare, but it's also possible for your patient to be allergic to the material used to make the orthosis. If that's the case, they might have an allergic reaction.
