Abstract: | Abstract
Dealing with pediatric fracture patients requires a funded knowledge of complications and remodeling capability of the youth skeleton to find the accurate therapy decision and to avoid unnecessary invasive procedures. Due to the different mechanical environment, fractures in children occur at specific fracture-vulnerable areas. One of those is the growth plate, which on one hand gives rise to the unique ability of correcting angular deformities by specifically increasing the growth rate in definite regions, and on the other hand leads to complications like growth arrest or angular deformity. The pediatric diaphysis presents the exclusive greenstick fracture, only seen in the growing skeleton, which occurs because of the different composition of the pediatric bone. To understand these very specific features of the youth skeleton, the molecular and cellular basis should be taken into consideration. Therefore, this review will present the common characteristics of skeletal development and fracture healing. An insight into the mechanotransduction as part of the remodeling and self-correcting ability of pediatric bone is given to span the bridge between clinical treatment options and scientific background. |
