Sustentaculum Tali Fracture Adjacent to Talocalcaneal Tarsal Coalitions

An 11-year-old boy demonstrated chronic medial hindfoot pain. A 12-year-old boy experienced acute pain and swelling in his right medial ankle and hindfoot after a fall. This is the first report of sustentaculum tali fractures adjacent to a talocalcaneal tarsal coalition, likely resulting from a stress riser created by a rigid subtalar joint.These 2 cases represent unique causes of foot pain in the setting of tarsal coalitions, never before described. Patient-reported outcome measures demonstrated expected improved outcomes after excision of tarsal coalition. Awareness to this possibility will help clinicians treating foot and ankle conditions in children optimize their care.
