Metacarpal Nonunion in a Two-Year-Old Child

Metacarpal fractures are common in childhood and adolescence and bone healing is the rule. Case Presentation: We present a two-year-old boy with an established nonunion of the fourth and fifth metacarpal fractures, treated successfully without any complications. Both fractures resulted from a high-energy trauma; although initial treatment seemed appropriate, nonunion occurred. The child was referred to our center for nonunion and humpback deformity. The patient was treated with open reduction/internal fixation and bone graft. All metacarpal fractures healed radiographically and clinically without any problem. The final functional and cosmetic result was excellent. Conclusions: Although the occurrence of metacarpal nonunion is rare in children, careful follow-up must be done to achieve osseous union.
