Introduction:
Arterial injury/entrapment is an uncommon sequelae of long bone fractures, particularly in closed injuries. The proximity of the anterior tibial artery to the distal tibia poses a risk of entrapment with a fracture at this level. To the best of our knowledge, this is the first case report of a partial nonunion due to entrapment of the anterior tibial artery in a healed tibia fracture in a pediatric patient.
Case report:
We describe a case of a 16-year-old male who presented with leg pain 2 years after a left distal third oblique tibia fracture. The fracture was initially treated non-operatively with excellent alignment. He did well for many months and returned to playing football with some vague persistent discomfort in his leg. Two years after the original injury, he was hit while playing football and started experiencing increasing left leg pain. The subsequent evaluation and findings are outlined here.
Conclusion:
This is an original case report of an adolescent patient with a partial tibial nonunion requiring surgical intervention. Possible entrapment of neurovascular structures should be considered when managing these patients following injury.
