Tibia growth plate closure
WebbThe proper function of these growth plates depends on an intricate balance between chondrocyte proliferation, which requires nourishment from the epiphyseal vessels, and chondrocyte death, which requires the integrity of the metaphyseal vessels. Webb25 feb. 2024 · Treatment for growth plate fractures depends on the severity of the fracture. The least serious fractures usually require only a cast or a splint. If the fracture crosses the growth plate or goes into the joint and is not well-aligned, surgery may be necessary.

Tillaux fractures are a transitional fracture of the growth plate. Most reports on Tillaux fractures are case series [28-31]. The most accepted mechanism of injury involves external rotation of the foot or internal rotation of the leg on a fixed foot [1, 5, 6].
Webb7 sep. 2016 · In their study, they found that the longitudinal growth in the DH tibia was not observed after 12 weeks of age . The reason for these discrepancies is not clear. However, Summer-Smith et al. suggested that the cessation of longitudinal bone growth may precede radiographic signs of the growth plate closure . WebbBefore closure, the growth plate is the most fragile part of the bone and is therefore frequently disrupted when force is applied. Growth plate fractures may extend into the metaphysis and/or epiphysis; the different types are classified by the Salter-Harris system .
