Question

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

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

Answer 1

The correct option is C Ligament break

The two long bones in 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. So, the correct answer is option C.
