Which age group is least likely to experience a dislocation or sprain when significant stress is placed on joints?

• A. 5-10 years
• B. 15-20 years
• C. 35-40 years
• D. 55-60 years

Answer: (A)

When joints face significant stress, the way injuries show up changes with age because bones, ligaments, and growth processes mature at different rates. In five- to ten-year-olds, the skeleton is still growing and the growth plates (physes) are the weakest link. Under stress, the bone around a growth plate tends to give way, producing growth-plate fractures rather than tearing ligaments or driving a joint out of place. Ligaments in this age are often able to withstand many forces that would cause sprains or dislocations in older individuals, so true dislocations or ligament sprains are less common in this group. As children get older and especially into adolescence and adulthood, higher activity levels and more mature tissues mean ligaments are more likely to fail before the bone, and dislocations or sprains become more common with sports or falls. This pattern explains why the five- to ten-year-old group is least likely to experience dislocation or sprain under significant joint stress.
