Characterstics of Trampoline-related fractures of the Proxim
The purpose of this study was to investigate the characteristics of trampoline-related proximal tibial fractures in young children. Trampoline-related fractures of the proximal tibial metaphysis are common in children and have been linked to subsequent valgus deformity of the tibia.

Researchers evaluated 40 patients with proximal tibial fracture after trampolining. The measurements recorded include the lower limb length, mechanical lateral distal femoral angle (mLDFA), medial proximal tibial angle (MPTA), mechanical axis deviation (MAD), and anatomical tibio-femoral angle (aTFA). The anterior tilt angle (ATA) was measured using a lateral radiograph of the tibia.

--The median age at injury was 40.0 months. Using trampoline with a heavier person was the most common mechanism of injury.

--aTFA and MAD were found to be increased towards the valgus at the last follow-up in our patient; however, the increase was not statistically significant.

--The anterior tilt angle was increased in the injured leg at the last follow-up. But the change was not statistically significant.

Finally, jumping on a trampoline with a heavier individual increases the risk of proximal tibial fracture in young children. After a minimum of one year of follow-up, there was a significant shift in limb alignment.
