Final answer:
c) Nodular thickening of flexor tendon is the sonographic appearance of Trigger finger
Step-by-step explanation:
The sonographic appearance of Trigger finger is characterized by c)nodular thickening of the flexor tendon. This condition, also known as stenosing tenosynovitis, involves inflammation and thickening of the flexor tendon, leading to difficulty in finger movement and a characteristic catching or snapping sensation.
Sonography, or ultrasound imaging, is a valuable diagnostic tool for assessing musculoskeletal conditions, including Trigger finger. When examining a patient with Trigger finger using ultrasound, the characteristic finding is the presence of nodular thickening along the flexor tendon. This nodular thickening represents the inflamed and hypertrophied tendon, contributing to the impingement and restriction of finger movement.
Understanding the sonographic appearance of Trigger finger is crucial for accurate diagnosis and appropriate management. Nodular thickening of the flexor tendon can be visualized in real-time using ultrasound, allowing healthcare professionals to assess the severity of the condition and plan the most effective treatment strategy.
Sonography provides a non-invasive and dynamic way to evaluate the soft tissues of the hand and identify the specific structural changes associated with Trigger finger.
