SHOULDER FACTS:
Shoulder problems are a common issue that affects a significant portion of the population. Here are some key facts and statistics about the prevalence and demographics of shoulder problems:
1. Prevalence:
- Shoulder pain is one of the most common musculoskeletal compalints, with studies suggesting that up to 67% of people will experience shoulder pain at some point in their lives.
- The annual prevalence of shoulder pain in the general populations ranges from 7% to 26%, varying based on age, occupation, and lifestyle factors.
2. Rotator Cuff Disorders:
- Rotator cuff tears are prevalent, particularly among older adults. Approximately 20% of individuals over the age of 60 are estimated to have rotator cuff tears, with the prevalence increasing with age.
- Full-thickness rotator cuff tears are found in about 30% of individuals over 70 years old.
3. Tendonitis and Bursitis:
- Shoulder tendonitis and bursitis are common inflammatory conditions affecting the shoulder. These conditions often result from repetitive motion or overuse injuries.
- Tendonitis and bursitis are frequently reported in athletes and individuals with occupations that involve repetitive shoulder movements.
4. Frozen Shoulder (Adhesive Capsulitis):
- Frozen shoulder affects approximately 2% to 5% of the general population, with higher prevalence in individuals aged 40 to 60.
- It is more common in women than men and is also associated with conditions like diabetes and thyroid disorders.
5. Osteoarthritis:
- Shoulder osteoarthritis affects about 5% of the population, with higher prevalence in older adults.
- It is more commonly seen in individuals over the age of 50, and the risk increases with age.
6. Gender Differences:
- Studies indicate that women are more likely to experience certain shoulder conditions, such as frozen shoulder and rotator cuff injuries, compared to men.
7. Impact of Age:
- Shoulder problems are more common in older adults due to degenerative changes in the musculoskeletal system.
- However, younger individuals, particularly athletes, are also at risk for shoulder injuries due to high levels of physical activity.
8. Occupational Impact:
- Certain occupations that involve repetitive shoulder movements or heavy lifting are associated with a higher risk of shoulder problems. This includes construction workers, manual laborers, and athletes.
- Shoulder injuries account for a significant number of work-related musculoskeletal disorders, leading to lost workdays and decreased productivity.
9. Healthcare Visits:
- Shoulder problems are a common reason for visits to primary care physicians, orthopedists, and physical therapists.
- They are among the leading causes of musculoskeletal pain-related healthcare visits, second only to back and neck pain.
