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.
