Digital artery damage associated with closed crush injuries.
This retrospective study describes closed finger crush injuries in seven patients (eight fingers) in which each finger sustained a loss of blood supply. Clinical findings included numbness, decreased two-point and sharp/dull sensation, cyanosis or pallor, and decreased capillary filling. Fractures, especially transverse fractures near the proximal interphalangeal joint or distal interphalangeal joint, were usually present and often showed longitudinal crush fracture lines. Exploration and revascularization were carried out in seven fingers, all of which survived. The only finger not explored progressed to necrosis and amputation. Crush injuries to the fingers, especially those associated with displaced fractures, should be carefully evaluated for symptoms and signs of ischaemia.
