Carpal and Metacarpal Anatomy

The video tutorial covers the anatomy of carpal, metacarpal, and phalangeal bones, detailing their structure, arrangement, and ossification processes. It explains the clinical implications of fractures, particularly scaphoid and metacarpal fractures, and their potential complications. The tutorial also outlines the ossification timelines for these bones, providing a comprehensive understanding of their development and clinical relevance.
