Which musculoskeletal disorder causes severe joint deformities and often affects younger people?

  1. Osteoporosis

  2. Rheumatoid arthritis

  3. Scoliosis

  4. Tendonitis

The correct answer is: Rheumatoid arthritis

Rheumatoid arthritis is the correct answer because it is an autoimmune condition that primarily affects the joints, causing inflammation, pain, and eventually severe deformities, particularly in the hands and feet. It is known to occur in younger individuals, often starting in their 30s or even earlier, which sets it apart from other musculoskeletal disorders that typically affect older adults. Osteoporosis, while a significant joint-related condition, primarily involves bone density loss and is more commonly associated with aging. Scoliosis refers to an abnormal curvature of the spine and is generally related to growth and development issues in adolescents rather than severe joint deformation. Tendonitis is the inflammation of a tendon, usually due to overuse, and does not typically lead to the severe deformities seen with rheumatoid arthritis. This is why rheumatoid arthritis is recognized for its impact on younger populations with severe joint deformities.
