Trampoline fracture of the proximal tibial metaphysis in children may not progress into valgus: a report of seven cases and a brief review
Abstract
Background: Fracture of the proximal tibial metaphysis in children is a rare injury but notorious for carrying the risk of subsequent valgus deformity of the tibia.
Hypothesis: Trampoline-caused fracture of the proximal tibial metaphysis in children may not progress into valgus.
Materials and methods: We followed up six children who collectively sustained seven fractures of the proximal tibial metaphysis while trampolining with other heavier and/or older children. Initial and follow-up x-rays were reviewed by an orthopaedic surgeons and two radiologists.
Results: None of the patients developed valgus deformity with follow-up.
Conclusion: Trampoline is associated with a specific type of injury to the proximal tibia when children are trampolining with other heavier children even without falling off the trampoline. This fracture is linear and complete, often non-displaced. Unlike "other" proximal tibial metaphyseal fractures, trampoline-associated proximal tibial metaphysical fracture in children is not associated with a risk of subsequent valgus deformity.
Level of evidence: Level 4.
Type of study: case series.
