To begin wrist week, we are starting with an overview on the anatomy of the wrist.
- The wrist joint is formed by a row of carpal bones, the radius and the ulna.
- The wrist is an ellipsoidal (condyloid) type of synovial joint which allows flexion, extension, abduction and adduction.
- Major muscles include flexor carpi ulnaris, flexor carpi radialis and flexor digitorum superficialis, extensor carpi radialis longus and brevis, extensor carpi ulnaris and extensor digitorum.
- Some major ligaments include ulnar and radial collateral ligaments and the dorsal and palmar radiocarpal ligaments.
- Wrist pain can come from sprains, fractures, repetitive stress and conditions like arthritis carpal tunnel syndrome, ganglion cysts etc.
- You may prevent wrist pain by building strength in the wrist, attaining adequate ROM of the wrist and learning proper ergonomics during tasks like computer typing.
Fun Fact: The palmaris longus is absent in approximately 15% of population! Here is how to check if you have one:
- If you have one, you should see a tendon that appears at the center of the wrist when you touch your thumb and pinky together. This test is called the Schaeffer's test.
- The first video is an example of someone who does have a palmaris longus muscle.
- The second video shows an example of someone who does not have this muscle.
- Research has determined that people who have this muscle have no greater wrist strength than people who don’t!
