- Abstract:
- Lower limb long bone fractures of femoral and tibial shafts are common in children.Frequent overgrowth at injured side may cause leg length inequality,low back pain,scoliosis and sciatica.The mechanism of overgrowth is probably related with the disruption of periosteum after fracture.The post-fracture periosteum reduces the pressure on growth plate and stimulates bone growth.Overexpression of related genes after fracture promotes proliferation and differentiation of chondrocytes and accelerates bone growth.This review summarized clinical and basic researches on the overgrowth of lower limbs after long bone diaphyseal fractures in children and elaborated upon the possible mechanisms of overgrowth.
