Title: Reporting Two Cases with Reappearance of Growth Plate after Trauma in Ankle
Abstract: Bone growth plates or physis are present at the end of long bones and are responsible for longitudinal growth. These plates consist of four layers and are lucent in radiography as a line perpendicular to the longitudinal axis. When the age increases and by bone maturity these line will be narrower and as longitudinal bone growth stops, the line disappears. This phenomenon occurs at different ages in different bones of the skeleton but with complete maturity at the age of 19, all growth plates are closed and sclerosed. Re-appearing after closing is uncommon. We introduce two young patients in this study who have been treated for an ankle cast after trauma. In the control X-ray the re-appearance of growth plates of tibia and fibula was observed. Subchondral bone resorption is a known phenomenon that will occur after six to eight weeks immobility in any bone. The lucent line is caused by imbalance in osteoblast and osteoclast activity and bone absorption. Re-appearing of growth plates in patients of this study could be due to reversed ossification and bone absorption.
