ínhüvelygyulladás

ínhüvelygyulladás, also known as tenosynovitis, is inflammation of a tendon sheath. Tendon sheaths are protective, lubricating layers that surround tendons, allowing them to glide smoothly through the body. When this sheath becomes inflamed, it can cause pain, swelling, and stiffness. The condition is often caused by overuse, repetitive motions, or injury. Common sites affected include the wrist (De Quervain's tenosynovitis), the thumb, and the Achilles tendon.

Symptoms typically include pain that worsens with movement of the affected limb, a feeling of crepitus or grating when the tendon moves, swelling, and tenderness along the tendon. The pain can range from a dull ache to sharp and intense, depending on the severity of the inflammation. In some cases, a palpable nodule or lump may form along the tendon.

Diagnosis usually involves a physical examination and a review of the patient's medical history, focusing on activities and any recent injuries. Imaging studies like ultrasound or MRI may be used to confirm the diagnosis and rule out other conditions. Treatment aims to reduce inflammation and pain, and prevent further injury. This often includes rest for the affected area, ice application, and non-steroidal anti-inflammatory drugs (NSAIDs). Physical therapy may be recommended to improve flexibility and strength. In persistent or severe cases, corticosteroid injections or, rarely, surgery may be considered. Prevention focuses on proper warm-up exercises, avoiding repetitive strain, and taking breaks during activities that involve repetitive motions.
