Review Question - QID 211726

A 65-year-old woman with the foot deformity depicted in figure A presents to your clinic for an initial evaluation. On examination, you are able to passively correct her deformity. She is, however, unable to perform a single-leg heel raise. She reports pain with ankle motion, and her symptoms are severe enough to interfere with her activities of daily living. The patient is otherwise healthy, but does live a fairly sedentary and low-demand lifestyle. What is the most appropriate initial treatment for this patient's pathology?
