Abstract:
The differential diagnosis of a trigger finger presents a clinical challenge. This case depicts a 32-year-old male patient who presented with persistent snapping of the right index finger at the metacarpophalangeal joint without localized tenderness despite previous surgical A1-annular ligament release. CT diagnostics demonstrated a prominent articular tuberosity. The MRI showed no pathological findings. Surgical revision with concomitant excision of the tuberosity restored smooth mobility of the index finger.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
01:22Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
