Carpal Tunnel Syndrome is caused from pressure on the median nerve.  There are several tendons and the median nerve that run from your forearm to your hand.   The tendons control movement in your hand and the median nerve controls feeling and movement in your thumb and first three fingers.   For these parts to get to your hand from your forearm they go through the carpal tunnel which is located in your wrist.  When the space in the carpal tunnel is restricted due to pressure or swelling is when symptoms appear.   Symptoms include pain, tingling, weakness or numbness in the fingers or hand.  Symptoms are usually present in the thumb and first three fingers although it is not unusual to have pain in your arms below your elbow.  The little finger is not affected because it controlled by a different nerve.

Cubital Tunnel Syndrome is caused from pressure on the ulnar nerve.  The ulnar nerve runs on the inner side of the elbow.  The ulnar nerve travels down your arm and though the cubital tunnel which is located around your elbow. When this nerve is compressed is when symptoms appear.  Symptoms can include pain in the forearm, weakness in the hand and numbness or tingling in the ring and small finger.

Ganglion Cysts are cysts that are filled with a clear liquid within the hand or wrist.  The cyst grows out of the joint surrounding the tissue.  They usually do not require treatment unless they interfere with function, cause pain or have an unacceptable appearance.

Mallet Finger is when you bend your finger or thumb but it cannot straighten itself at the tip.  It is caused when force is applied to the finger.  The injury is to the tendon but can also can include a bone fracture.  Symptoms include pain and the inability to straighten the finger or thumb.

Trigger Finger / Trigger Thumb is when the digit locks when bent because the tendons become swollen or inflamed.  The tendons come from the muscles in the forearm and attach to small bones in the fingers and thumb.  To keep the tendons in place, they slide through though a tunnel called the tendon sheath.  When the tendons become swollen they cannot slide easily though the tendon sheath and this is what causes the digit to lock, snap or pop.

Dupuytren’s Contracture, also called Dupuytren’s Disease, are lumps and pits within the palm caused by an abnormal thickening of the tissue beneath the skin.  The fingers become permanently bent in a flexed position and cannot be straightened completely which can complicate everyday activities.
