Bone fractures in which the bone protrudes through the skin are called

(A) greenstick fractures.

(B) compound fractures

(C) simple fractures.

(D) stress fractures.

The correct answer will be - compound fracture.

Explanation:

Bone fracture is the breaking of bone due to accidents, sports injuries, falls, osteoporosis and low bone density.

The fracture should be of various types depending on the degree but a type of fracture where a fractured bone protrudes out from the skin is known as an open fracture or compound fracture. The open fracture can also be a case of a medical emergency as it could lead to osteomyelitis, a type of bone infection.

Thus, the compound fracture is the correct answer.
