The Hand

is a very complex tool that, until injured, we may not fully appreciate it's value.  Within our hands/forearms there are many structures we need to protect and care for.

Bones

Our supporting structure.  Includes the phalanges (bones in the fingers), metacarpals (bones in the hand), carpals (bones in the wrist) and the radius and ulnar (long bones in the forearm.)  Fractures are the most common injuries to our bones

Joints

The point where bones meet and allow movement.  Joints can be affected by fractures that include a disruption to the articular surface, as well as conditions such as rheumatoid arthritis and osteoarthritis

Ligaments

Strong fibrous tissue connecting bones and stabilizing the joint.  Ligaments can be stretched causing a sprain, disrupted with a dislocation of the joint.  Full tears can also occur, commonly found in sport's injuries.  The most common ligament injury of the hand involves the ulnar collateral ligament of the thumb.

Nerves

These structures allow us to feel, coordinate movemement and protect our hand from heat and sharp objects.  There are 3 main nerves in the hand, with many small branches that are also susceptible to injury.  The median nerve can become compressed causing Carpal tunnel syndrome.  Cubital Tunnel syndrome involves a compression of the ulnar nerve, and the radial nerve is less commonly injured but can become compressed at the radial tunnel.

Muscles/Tendons

These structures allow movement and provide strength.  Muscles connect to bones frequently by a tendon, a rough fibrous tissue.  Both muscles and tendons are frequently injured during daily activity and repetative forces.  Lateral epicondilitis, medial epicondilitis and deQuervan's Tenosynovitis are common forms of tendonitis found in the upper extremity.  Other common hand injuries include trigger finger which can involve one or multiple digits and often develops over time.  A mallet finger is a more traumatic injury with a disruption to the tendon on the back of the finger.
