What is trigger finger?
Have you noticed that it is difficult for you to move your fingers? Do you feel pain or clicking in them in the morning as you begin stretching for the day? If you work a job or play a sport that requires repetitive movements with your hands and fingers, you might have a condition called ‘trigger finger.’
Trigger finger is caused by inflammation of one of the tendons, or cord-like structures, on the palm side of the hand that allow the fingers and thumb to bend. The tendon is encased in a fluid-filled tube or sheath, which allows it to glide more easily.
When the tendon becomes inflamed, it becomes difficult to bend or straighten the finger or thumb, often resulting in a clicking or catching feeling at the middle knuckle of the finger. This is also referred to as stenosing tenosynovitis.
If you’re dealing with this condition, let a Cascade Hand & Orthopedic Rehab therapist know. Our Fort Myers, FL clinic is here to help you with hand therapy techniques, and we can also offer you guidance on managing pain symptoms at home. Give us a call today!
Common causes of trigger finger?
Often the cause of trigger finger is unknown; however, trigger finger may occur with repeated gripping, or with the use of tools, such as a drill or wrench. It is also more common in people with diabetes, arthritis or when there has been an injury to the palm of the hand.
What are the symptoms of trigger finger?
Pain and a small nodule or bump in the palm of the hand may be the first signs of trigger finger. Tenderness and swelling at the base of the finger or thumb may be felt by a doctor or certified hand therapist. The patient will be instructed to make a fist and then straighten his or her fingers.
The affected finger or thumb may stay curled and then suddenly pop to a straight position, as if releasing the trigger of a gun. This repeated catching and releasing continues to irritate the tendon. If the condition persists for several months, the finger may become stiff.
Although this condition is bothersome and quite painful, hand therapy in Fort Myers, FL at Cascade Hand & Orthopedic Rehab can help!
What is the treatment for trigger finger?
If the symptoms are mild, the physician may prescribe anti-inflammatory medication. If the triggering is moderate to severe, the physician may recommend a cortisone injection along with a custom-made orthosis designed to rest the finger. Surgery may be recommended if resting or injections do not relieve the triggering.
How can a hand therapist help me?
Your primary care physician may refer you to a hand therapist at Cascade Hand & Orthopedic Rehab for non-operative and post-surgical treatment.
For non-operative treatment, the certified hand therapist has specialized training to fabricate a custom orthosis to rest the finger, and to teach the patient exercises to avoid stiffness during the healing process.
The certified hand therapist will also discuss ways to modify activities while the finger is healing. Hand therapy following surgery will improve range of motion, and teach the patient how to regain the function of the hand.
