      Subtalar arthroereisis has been used for the treatment of symptomatic flexible flatfoot deformities in both pediatric and adult patients. Chronic sinus tarsi pain is the most common complication of this procedure and can be relieved by removal of the implant. We describe a case of spontaneous fusion of the subtalar joint after arthroereisis. This is an irreversible complication that should be described to the patient as a rare, but possible, outcome of arthroereisis of the subtalar joint.

          I read with interest the report by Liu, titled “Spontaneous Subtalar Fusion: An Irreversible Complication of Subtalar Arthroereisis” (J Foot Ankle Surg 53:652–656, 2014). Reporting surgical complications is very important to educate surgeons of a potential negative situation, understand what led to the problem, identify errors on the part of the physician and/or patient, avoid or prevent its recurrence, and, once identified, take proper early action to correct the condition. The case described in the report by Liu is one in which, I believe, the complication could have (and should have) been prevented if the treating surgeon had recognized the malposition of the sinus tarsi implant, which is clearly shown in Fig. 3D of the report.
