Trigger finger is best defined as a medical condition wherein one of the fingers of the hand exhibits a limitation of movements when an attempt is made to straighten a bent finger.

To illustrate the condition is characterised by the finger getting stuck while straightening and then suddenly straightening out with a ‘pop’.

It was in 1850 when Notta first discovered this potentially disconcerting condition.

 

THE CAUSE

There are numerous trigger finger causes the more common ones may well include the presence of associated conditions such as Rheumatoid Arthritis and Diabetes. While women have a higher predilection compared to men, it is the 40 to 60 years age group which is prone to contracting a trigger finger injury. Typically contracted while involved in a strenuous activity of the hands the incidence of trigger finger globally is far higher than one would believe.

Statistics indicate that the lifetime risk incidence for a trigger finger is 2 to 3% whereas it could be as high as 10% in Diabetics. Thus it is scarcely surprising that there are innumerable options when the context is how to cure trigger finger maladies.

TREATMENT DEMYSTIFIED

A potentially disabling condition the treatment for trigger finger symptoms is diverse and may well include the likes of splints, drugs and even surgery. When the objective is how to cure trigger finger maladies options may range from primarily resting the affected joint and hand to even prescribing anti-inflammatory drugs which would reverse inflammation.

Concurrently it is not uncommon for physicians to prescribe steroid injections into the tendon sheath. This is common in instances where the more conventional treatment for trigger finger proves to be ineffective.

TRIGGER FINGER AND ERGONOMICS

One of the popular trigger finger causes is arguably indiscriminate use of the mouse while working on a computer terminal. The typical movement wherein the index finger repeatedly presses on the mouse can lead to a swelling and inflammation of the tendon sheath. This is best classified as a trigger finger.

This ergonomic malady is best corrected by using an innovative ergonomically designed mouse which would minimise the probability of irritating the tendon sheaths in the hand and thus prevent onset of trigger fingers in most instances. An ergonomic mouse designed with an alternate way to scroll the page rather than the traditional scroller. Experts recommend a mouse like the Orthomouse that allows the scroll to be done through buttons with a maximum of three movements needed rather than continuous scrolling of the scroll wheel.

The typical ergonomically designed mouse would eliminate the need for tapping on the mouse several thousand times every day. The use should not need to lift their finger for every click, there should be just a downward force needed. This is best achieved by ensuring that the mere weight of the hand placed in an anatomically comfortable position would be enough to single click the mouse. On the contrary a button strategically placed in opposition to the position of the thumb could well help in double clicking the mouse, this option has been used in the Evoluent Vertical mouse. It is important to use an ergonomically designed mouse that supports your hand and has light touch buttons that do not require much force to press them.

 

THE DEBATE

One of the most keenly contested conditions in healthcare, the treatment for trigger finger continues to be a puzzle and a debate for most. This is not surprising considering that the treatment options presently available in the market are symptomatic and curative but definitely not preventive. On the contrary the need of the hour is to find the right mix between prevention and cure if the objective is how to cure trigger finger. Remember whatever mouse you are using it is vitally important to take micropauses regularly through out the day. The are little breaks for about six seconds that you should take every 10 – 15 minutes .
