A coccyx with four vertebrae below the sacrum. The coccyx is formed of three, four or five rudimentary vertebrae.It articulates superiorly with the sacrum.In each of the first three segments may be traced a rudimentary body and articular and transverse processes; the last piece (sometimes the third) is a mere nodule of bone.
A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]

In bone surgery, a corticotomy is a cutting of the bone that may or may not split it into two pieces (bone fracture) but involves only the cortex, leaving intact the medullary vessels and periosteum. Corticotomy is particularly important in distraction osteogenesis or surgically facilitated orthodontic therapy.
The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass between the ages of 25 and 30. [2] The human skeleton can be divided into the axial skeleton and the appendicular skeleton.
