Which type of fracture occurs due to twisting or rotational forces on the bone?

A closed fracture is a fracture where the skin remains intact over the fractured bone, and there is no open wound at the site of the fracture.

a. A fracture where the bone breaks through the skin: This type of fracture is known as an open or compound fracture, where the bone pierces through the skin.
b. A fracture where the bone is out of alignment: This type of fracture is known as a displaced fracture, where the bone fragments are not aligned properly.
c. A fracture where the bone is completely broken in two: A complete fracture refers to a fracture that results in two separate bone fragments, but it does not necessarily involve the skin.

Osteoporosis is a condition characterized by weakened and porous bones, leading to an increased risk of fractures, especially in the hip, spine, and wrist.

a. Arthritis: Arthritis is a condition that involves joint inflammation and may cause joint pain and stiffness but does not directly weaken bones.
b. Osteoarthritis: Osteoarthritis is a degenerative joint disease that affects the cartilage and joints, but it does not specifically increase the risk of fractures.
c. Osteomyelitis: Osteomyelitis is a bone infection that can lead to bone destruction and inflammation but does not directly weaken bones to the same extent as osteoporosis.
