Some conditions associated with the fingers are trigger finger, De Quervain's disease and Dupuytren's contracture. Trigger finger is a condition that causes one of the fingers to become locked in a bent position while De Quervain's disease is a condition that causes painful and swollen tendons, as related by the Cleveland Clinic. Dupuytren's contracture is due to thickening of the tissue layers in the palm of the hand that leads to a finger becoming bent, as explained by the American Academy of Orthopaedic Surgeons.
A trigger finger, which is a painful condition, is also called stenosing tenosynovitis. The cause of this condition is associated with inflammation of the tendon sheath under the finger that is affected, as reported by Mayo Clinic. This can affect the finger's movement, causing it to become bent. Treatment options can include the use of a splint, finger exercises, steroid injections or a surgical procedure.
Although De Quervain's disease is also related to a tendon inflammation problem in the hand, the finger affected by this condition is the thumb. The condition causes pain up to the forearm, as stated by the Cleveland Clinic. The causes of this disease can be overuse or rheumatoid arthritis. Treatment can involve using a splint or surgery if other treatments do not work.
Dupuytren's contracture does not have a specific known cause, according to American Academy of Orthopaedic Surgeons. However, there can be contributing factors to this problem like heredity. Once the contracture occurs in the affected finger, the finger cannot be straightened. It is a condition that has a slow progression and may be treated with splints, steroid injections or surgery.
