b. Fracture
c. Dislocation
d. Stress fracture
ANS: A
Sprains account for approximately 75% of all ankle injuries in children. A sprain results when the trauma is so severe that a ligament is either stretched or partially or completely torn by the force created as a joint is twisted or wrenched. Joint laxity is the most valid indicator of the severity of a sprain. A fracture involves the cross-section of the bone. Dislocations occur when the force of stress on the ligaments disrupts the normal positioning of the bone ends. Stress fractures result from repeated muscular contraction and are seen most often in sports involving repetitive weight bearing such as running, gymnastics, and basketball.
