GROSS ANATOMY

Detailed explanation-1: -The main finding in this study is that carpal bones start to ossify in the first year of life, starting approximately at the age of 6 months.

Detailed explanation-2: -Bone ossification, or osteogenesis, is the process of bone formation. This process begins between the sixth and seventh weeks of embryonic development and continues until about age twenty-five; although this varies slightly based on the individual.

Detailed explanation-3: -The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. There are eight carpal bones, which divide into two rows: a proximal row and a distal row.

Detailed explanation-4: -Bone age is calculated by comparing the left wrist radiographs of the subject with the nearest matching reference radiographs provided in the atlas which are standard for different ages provided in the atlas. This method is simpler and faster than other radiograph based methods.
