The flexor tendon of the finger is surrounded by the tendon sheath, the inner layer of the tendon sheath is a closed synovial sac, and the outer layer is a non-stretchable fibrous fibrous sleeve composed of a sheath-like ligament and a phalanx. When the tendon sheath is swollen, the pressure rises, which can cause tendon ischemia and necrosis. The little finger and the thumb tendon sheath communicate with the ulnar and temporal sac sac, respectively, and the inflammation of the former can spread to the latter.
