An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. [2] A bone fracture may be the result of high force impact or stress , or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis , osteopenia , bone cancer , or osteogenesis imperfecta ...
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
Signs and symptoms include crepitus (a crunching sound made when broken bone ends rub together), [1] pain, tenderness, bruising, and swelling over the fracture site. [4] The fracture may visibly move when the person breathes, and it may be bent or deformed, [4] potentially forming a "step" at the junction of the broken bone ends that is detectable by palpation.

The human pelvis exhibits greater sexual dimorphism than other bones, specifically in the size and shape of the pelvic cavity, ilia, greater sciatic notches, and the sub-pubic angle. The Phenice method is commonly used to determine the sex of an unidentified human skeleton by anthropologists with 96% to 100% accuracy in some populations.

Patella fractures make up about 1% of all broken bones. [6] Males are affected more often than females. [3] Those of middle age are most often affected. [3] 6% to 9% of patellar fractures are of the open type. [11]
