Anatomy of Fingers Across Ages
Fingers contain bones called phalanges, joints, tendons, and nerves. In teens, fingers are still developing, with growth plates active at the ends of bones. In older adults, cartilage may thin and joints can stiffen. Understanding basic finger anatomy helps explain why injuries or pain patterns can differ by age.
Common Finger Injuries and Conditions
Teens often experience jammed fingers, sprains, or fractures from sports. Older adults may face arthritis, trigger finger, or reduced grip strength. Repetitive motions, such as typing or gripping tools, can strain tendons over time. Early care and proper ergonomics can reduce long-term issues.
When to See a Healthcare Provider
Seek medical advice for persistent pain, swelling, numbness, or limited range of motion. A provider can use imaging and exams to diagnose fractures, nerve issues, or joint damage. Treatment may include rest, splinting, therapy, or, in some cases, surgery.
