What is X-ray of a child's arm after a fall appears to show a fracture near, but not at, distal end of the ulna. Before diagnosing a fracture, you should also consider the possibility that this is actually which of the following? and explain in detail?
The epiphyseal plate of the bone contains cailage that is radiolucent. The plate in a bone that is not yet fully ossified can produce a "line" crossing the bone near the end. This may be easily mistaken for a fracture by the inexperienced. Anatomically, the epiphyseal plate separates the epiphysis from the diaphysis.
