Abstract:
A 13-yr-old adolescent boy presented with wrist pain after falling off a scooter onto his outstretched hand. Radiographs revealed a nondisplaced hairline fracture of the scaphoid bone and an irregular radiolucent line in the proximal metaphysis of the second metacarpal bone, consistent with an anomalous growth plate, or complete pseudoepiphysis. Complete pseudoepiphysis is a rare finding, with only a few cases reported. Learning about the common locations of growth plates and the radiographic differences between normal, injured, and anomalous growth plates can help decrease physician error and improve patient outcomes.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
