The Anatomy of the Hand
The hand and wrist is composed of many muscles, tendons and nerves. These contribute to the mobility, grip and flexibility of the hand.
The hand contains 19 bones, not including the carpal or wrist bones. The bones are placed into two categories, metacarpals and phalanges.
Five metacarpal bones are found in each finger. These metacarpal bones contribute to the movement of each finger. There are also fourteen interphalangeal joints. The index, middle, ring and pinky finger each have three interphalangeal joints while the thumb has only two.
Importance of the Hand
Similar to the wrist, the hand is vital to daily activity. It would be difficult thinking of a daily task that does not require the use of your hand. From turning a doorknob to driving a car, having a healthy hand is important.
If you are experiencing hand or wrist problems from over usage, long-term pain, or have a recent injury please contact Tri-City Orthopaedics.
The Anatomy of the Wrist
The wrist, or carpus, is made up of eight carpal bones. The carpal bones are aligned in two rows, the proximal and distal. The wrist also consists of the distal ends of the ulna and radius. The ulna and radius are the two bones that help to make up the forearm.
When something goes wrong, and your joints, cartilage, and bones stop working or cause you pain, in an instant simple tasks can become a uncomfortable.
The Importance of the Wrist
The wrist joint is used in conjunction with the hand in just about every day-to-day activity. Over use of the wrist can happen in both sports activities and the workplace limiting ones participation in either.
