Normally, the connective tissue slides easily in and out of the sheath as you bend and straighten the finger. In trigger finger the connective tissue can slide out of the sheath once you bend your finger. However, it cannot easily slide back in due to the swelling. The finger then remains bent (flexed) unless you pull it straight with your other hand.

Steroids work by reducing inflammation. A finger splint could also be suggested for a number of days after the injection to rest the finger. This treatment works in concerning nine in ten cases. A second injection could also be needed if the first does not work.

Surgery

An operation done under anesthetic agent could also be suggested if the above does not work. A little cut is sometimes made at the bottom of the finger and the connective tissue sheath is widened. The operation is mostly very winning.

An alternative operation may be a transdermal trigger finger release. A needle is employed to release the tight mouth of the tunnel so an open operation is avoided.

Sometimes, trigger finger is an associated condition ensuing from an underlying disease that causes inflammation of tissues of the hand, such as rheumatoid inflammatory disease. In fact, knowledge conferred at the 2005 American faculty of medical specialty national meeting instructed that a majority of patients with autoimmune disorder have inflammation round the tendons of the palm of the hand that would be converted into trigger finger. 

What is the treatment for trigger finger?

Stretching, ice, and anti-inflammation treatments may be useful. Oral antiinflammatory medications that will be useful embody nonsteroidal anti-inflammatory drug, ibuprofen,diclofenac, and others.

The fastest and handiest treatment could be a native Cortone Acetate injection into the connective tissue sheath round the affected connective tissue. Most patients can respond completely to the Cortone Acetate injection; however this might solely be a short lived response. once a trigger finger persists when 2 injections and isn’t attentive to the on top of treatments, surgical procedures to unleash the connective tissue sheath and/or take away the inflamed or scarred tissue area unit thought of. Surgical intervention is sometimes a permanent cure for this condition.

•           Tendon sheath is sort of a cowl that wraps round the connective tissue to assist it glide swimmingly once the finger bends and straightens.

•           Pulleys form a tunnel to carry the connective tissue near the bone.

Swelling makes it tough for the connective tissue to glide through the block tunnel, leading to triggering.
