Hand Surgery. Trigger Finger, Dupuytren's contracture, or Trigger thumb and Anatomy of the hand.
Trigger finger, or Trigger thumb, or Trigger digit, is a common disorder of later adulthood characterized by catching, snapping or locking of the involved finger flexor tendon. A disorder, associated with dysfunction and pain. Trigger Finger is that fingers get stuck in a bent position, and then straightens out again during an audible and often painful popping, which is due to finger flexion has too little space in the tendon sheaths. It is not known why this phenomenon occurs. Hand Surgery treats disorders localized in the forearms, wrists and hands. The most frequent interventions made for trigger fingers, coachman hand, tendon nodules inside pinched nerve in the wrist (carpal tunnel syndrome) and osteoarthritis of the thumb. Furthermore, insertion may be carried out by the artificial hand and finger joints, as an alternative to a "stiffening". Other causes of pain and stiffness in your hands, such as osteoarthritis or rheumatoid arthritis.
Trigger Finger - digitus saltans syndrome
Finger "jumps" when the unevenness of the tendon has to pass in and out of the tendon sheath. Flexor tendons of the fingers, which runs from the finger joints and out to the outer links are enclosed tendon sheaths. Tendon sheath ensures that the tendons follow the bones in your fingers - even when the fingers bend. If there is a slight thickening of the tendon, there is no longer room for the tendon within the tendon sheath and tendon can be trapped when the finger is moved. Often it is difficult to bend and extend the finger. When the finger is straightened, sitting bow tendon fixed for a moment until the muscle force is great enough to overcome the obstacle of the tendon sheath. You hear a little snap, and the finger be suddenly stopped. Therefore it is called state of "trigger finger" (or Dupuytren's contracture).
Causes and symptoms of "trigger finger"
The symptoms of trigger finger is the finger springs back and can lock onto. Additionally there may be pain. The reason for the development of the "trigger finger" are often unknown but can be found in, among other things diabetes. The disease is relatively common. It occurs in all age groups and often without an external cause. Diabetes Patients may develop the condition in many fingers, which may require several operations. Patients complain of soreness in the finger joints and pain when the finger is bent. When the finger is moved, one can also hear the characteristic clicking sound when the tendon passes through the tendon sheath. Sometimes you can feel a hard lump on the flexor tendon in the palm just bøjefuren. If symptoms persisted for several weeks, is an operation usually required.
Surgery for Trigger Finger (Dupuytren's contracture)
The aim of surgery is to remove pain and jumping tendency of the finger. The operation consists in cutting through a short tunnel at the bow tendon, leaving room for the node. The tunnel can be dispensed with. The operation is performed in an outpatient under local anesthetic and takes about 10-15 minutes. The doctor applies a local anesthetic in the palm of the hand. To reduce bleeding from the surgical year, the operation is performed in blood emptiness. You get a cuff on the upper arm, which is inflated during the operation. The doctor puts about 3 cm long incision in the palm of the hand and cuts through the tight tendon sheath. The skin is sewn together and being brought a bandage. The first day to the hand held high, preferably above heart level. As with all operations there is a small risk of infection, bleeding or phlebitis, and there is a small risk of damage to other structures in the hand. You may use your hand as much as physically possible.
After the operation of "jumping the finger"
Inflammation can occur after any operation, but is relatively rare after surgery for 'trigger finger'. Some patients have damaged a sensory nerve or get a blood clot in his hand. Operation The wound is closed with threads that are removed by the practitioner 2 weeks after surgery. The first 2 days after surgery has been a great dressing to the hand, according to which the dressing is replaced with patches. When pain can take painkillers or medicine. One must expect to be sick 1-2 weeks depending on how hard a job you have.
The hand and wrist function and anatomy
Hands consist of many small bones. Each hand has 27 bones. The wrist is a complex framework consisting of forearm bone spool pin and 8 carpal bones. By using many small heel of the hand ligaments, bones are tightly connected to each other. The 4 outer carpal bones is through a root joint associated with the 5 metacarpal bones that form the transition to the finger bones. There are a total of 14 finger bones. They are divided into 4 fingers, each with 3 knuckles and thumb with 2 bones. Metacarpal bones and finger bones are connected by basic joints, intermediate and outer sections. The thumb, however, only basic joints and outer sections. Besides the bones contain the hand and wrist several tendons that bend and stretch your fingers, many ligaments that connect and support the wrist and finger joints, and many fine small blood vessels and nerves. Furthermore, the hand and fingers several small muscle groups. At the top and underside of the wrist are a number of small channels in which the tendons, blood vessels and nerves pass from the forearm of the hand. On the underside of the wrist called the carpal tunnel channel. On the upper side shows the same principle, just run this other tendons, arteries and nerves. Muscle tendons around the wrist is surrounded by tendon sheaths.
