If you rupture the extensor tendon, finger will look flexed at 30 degrees. Sometimes it is associated with an avulsion fracture. Signs of mallet finger: pain at dip; xray shows avulsed bone on dorsal proximal distal phalanx, unable to extend distal end of finger (carrying at 30 degree angle, point tenderness at sight of injury. Caring for mallet finger: rice and splinting (in extension) for 6-8 weeks, keep the brace on at all times. Cause of boutonniere deformity: rupture of extensor tendon dorsal to the middle phalanx. Forces and locks dip joint into extension and pip into flexion. You can passively move the joint out of this lock: this can occur when the tip of the finger gets a blow.
