Stenosing tenosynovitis, or more commonly "trigger finger" is a disease that can severely impact a patient's quality of life. Its incidence is said to be 28 persons per 100,000 annually. The disease is manifested in one or more fingers by finger locking in flexion or extension, leading to pain, discomfort and at times, loss of function. Patients frequently report having to snap their fingers back in position to alleviate symptoms. The pathophysiology relates to thickening of the flexor tendon sheath, which can impair tendon gliding within it.
