Question

A person met with an accident in which two long bones of the hand were dislocated. Which among the following may be the possible reason?

• A. Break of skeletal muscle
• B. Areolar tissue break
• C. Ligament break
• D. Tendon break

Answer 1

The correct option is C Ligament break

The two long bones in the hand are the radius and the ulna. Annular ligament or orbicular ligament is a strong band of fibres present on the head of the radius that retains it in contact with the radial notch of the ulna. The person must have broken the ligament, which dislocated these long bones leading to fracture. In the case of tendons, they join skeletal muscles to bones, and a break causes inflammation. A break in skeletal muscles cannot be responsible for the dislocation of bones as bones are joined by ligaments. Areolar tissues are found around muscles, nerves, and blood vessels, so they are in no way concerned with bones.
