Arthroereisis has been shown to be an effective procedure to treat pathologic hyperpronation and flexible flatfoot accompanied by talotarsal instability in both children and adults. It is imperative that the clinician examines both the patient’s clinical presentation as well as radiographic evaluation to determine appropriateness of the procedure. Highly satisfactory results have been reported both functionally and radiographically with use of the arthroereisis procedure. Most common complications reported in the literature are transient and easily reversible by removal of the device. Although there is a plethora of reported pediatric clinical evidence in the literature, there remains a lack of clinical trials in the adult population. In this article, we examine the current literature with respect to the adult and pediatric populations while also referencing the senior author’s personal experience with the subtalar arthroereisis procedure.
