A ten-year-old female underwent open reduction and internal fixation of a Hawkins type III fracture of the talar neck. The fracture united within three months. However, avascular necrosis of the body of the talus occurred. Partial collapse of the talar body ensued despite protection from weight-bearing for eight months after surgery. This case illustrates that fracture-dislocation of the talus can occur in a child and has a guarded prognosis.
