Rule out a volar plate or collateral ligament injury to the right SF PIP joint. Evaluation of the fifth finger on several sequences is limited by excessive noise.The PIP joint is held in slight flexion. There is edema likely representing bone contusion from prior injury in the head of the proximal phalanx and the base of the middle phalanx. There is also a small amount of fluid in the PIP joint. The collateral ligaments of the PIP joint appear intact. The volar plate appears intact. The flexor tendon apparatus appears normal. The extensor tendon is difficult to see dorsal to the middle phalanx but its attachment to the middle and distal phalanges appear intact. Although the A2 pulley is difficult to visualize, we suspect that it is intact.
Bony contusions in the head of the proximal phalanx and the base of the middle phalanx of the right fifth digit. We see no findings to indicate collateral ligament injury or volar plate injury.
