In this episode of OT Conversations, Hao, an occupational therapist, discusses trigger finger, also known as stenosing tenosynovitis. The condition is characterized by a finger or thumb getting stuck in a bent position and suddenly straightening with a snapping motion. Hao explains the anatomy involved, including the flexor tendons and tendon sheaths. Causes of trigger finger include long-term irritation, overuse of the flexor tendons, repetitive hand movements, underlying medical conditions, and hormonal changes. Symptoms include finger stiffness, popping sensations, and locked fingers. Diagnosis involves physical examinations, provocative tests, and ultrasounds. Non-surgical treatments include rest, activity modification, splinting, ice or heat therapy, and gentle stretching exercises. Medical interventions include steroid injections and hand therapy, while severe cases may require surgical treatments. Preventative measures are emphasized, such as avoiding excessive gripping, using ergonomic tools, and managing underlying conditions. Hau concludes by stressing the importance of patient education and preventative intervention.
