Irreducible Salter Harris type II distal tibial physeal fracture secondary to interposition of the posterior tibial tendon: a case report.

Pediatric distal tibial fractures generally occur without significant long-term sequelae, and patients are commonly able to return to their preinjury activities after proper management. The literature reports excellent outcomes after anatomical reduction of distal tibial and ankle physeal fractures with closed or open treatment. Treatment options include simple immobilization of nondisplaced fractures, and closed or open reduction for restoration of anatomic alignment of displaced fractures. Soft tissue interposition within the fracture can threaten successful closed reduction, and may warrant open management if closed reduction fails to produce a satisfactory result. Despite the documented possibility of soft tissue interposition preventing closed reduction of pediatric ankle fractures, there is a paucity of literature reporting this complication. We report a unique case of an irreducible Salter-Harris type II distal tibial physeal fracture secondary to interposition of the posterior tibial tendon.
