Flexor tendinitis

What is flexor tendinitis?

Flexor tendinitis is swelling in the tendons that help control hand movement. Tendons are bands of tissue connecting muscles to bones; the flexor tendons run from the forearm, through the wrist and across the palm, allowing the fingers to be bent.


Damage can be caused by repetitive and strenuous activities such as throwing. Tendons can also become inflamed as a result of rheumatoid arthritis.


Inflammation of the tendon, causing pain and swelling on the inside of the elbow when throwing and sometimes during rest.


During a medical examination the doctor will ask you to bend and straighten your fingers, and test your finger strength. You may also have an X-ray or MRI scan to see if there is damage to the bone.


Non-operative treatment includes resting, using ice to reduce swelling, and taking anti-inflammatory medication (if advised by your doctor). It’s a good idea to avoid activities that involve gripping, or repeatedly squeezing with your hand while you are recovering as these can put more stress on the tendon. If the symptoms do not improve, you may offered cortisone injections; however, if the tendon has been ruptured, you may be advised to have flexor tendon repair surgery.
