More than almost any other part of the body, the fingers remain in nearly constant use even during periods of relative inactivity.  Swelling, soreness and other problems in the fingers and knuckle joints may indicate more serious and potentially debilitating issues and should be attended to immediately if they persist.

Trigger Finger 
A trigger finger or trigger thumb is a condition in which the movement of the affected digit is arrested for a moment while flexed or extended, and then continues with a jerk upon continued effort.  This irregularity results from thickening and constriction of the mouth of the fibrous tendon sheath through which the affected tendon travels.  The thickened sheath interferes with the normal, free glide of the flexor tendon within, and the tendon develops a swollen area as a result.  Trigger finger occurs most commonly in the ring or middle fingers, and most commonly affects the fingers of middle-aged women and the thumb in infants or small children.  It has been known to cause disability in long-term diabetic patients.

Finger Sprains & Dislocations 
Finger sprains and dislocations are injuries to the ligaments and soft-tissues around the small joints of the fingers.  It is important to obtain a proper diagnosis of a finger sprain or dislocation so that your treatment is appropriate for the injury.

Ganglion Cyst 
Wrist ganglion cysts are lumps around the wrist and hand.  Wrist ganglion cysts are benign collections of synovial fluid that originate either in a joint or tendon sheath.

Dupuytren's Contracture 
Dupuytren's contracture is a thickening and contraction of the tissue on the palm of the hand.

Ulnar Collateral Ligament Tear 
An injury to the ulnar collateral ligament (UCL) of the thumb is also called gamekeeper's thumb or skier's thumb.  These names describe how the thumb is injured when patients tear the ulnar collateral ligament, a mishap known as a UCL injury.

Mallet Finger (Baseball Finger) 
Mallet finger, also known as baseball finger, is an injury to the fingertip caused by a blow to the end of the finger.

Cracking Joints 
Any joint cracking should be evaluated if it causes pain.  It could stem from a variety of causes, including arthritis, hairline fractures and degeneration.
