Stenosing Tenosynovitis Treatment
Trigger finger, or stenosing tenosynovitis, is a condition in which any of the fingers or the thumb attempt to flex closed while gripping. A patient with trigger finger will experience a stuttering motion of the finger before snapping closed, unlike a smooth, continual closure. Trigger finger is often painful and causes swelling at the base of the affected finger on the palm of the hand.
Trigger finger is caused by localized swelling instigated by inflammation or scarring around the tendons that normally pull the affected finger inward toward the palm which is known as flexion. Trigger finger usually occurs as an isolated condition, but is sometimes associated with underlying illnesses that cause inflammation of the tissues such as rheumatoid arthritis.
Depending on the severity of the condition, treatment recommendations may be conservative. The goal is restoration of normal, painless use of the involved fingers and correction of the chronic inflammatory process. In some cases, symptoms can be relieved by changing activities or by stretching exercises. Anti-inflammatory medication may be prescribed to relieve swelling and pain. The most rapidly effective treatment is a local cortisone injection around the affected tendon. Most patients will respond to the cortisone injection. The rehabilitation team at The Centre for Working Hands may also incorporate treatments that include splinting, edema management and PROM exercise programs.
When symptoms do not improve through rehabilitation, hand surgery may be needed. During this surgical procedure, your hand surgeon will release the fibrous sheath to allow more space for the gliding tendon and reduce the inflammatory response. There may be some continued pain and joint stiffness after the surgery.
