“…While the need for open reduction may prompt consideration of conservative management, it is important to note that the ECU plays an important role in wrist motion and dynamic stabilization. 3 Furthermore, in analogous avulsion fractures of the extensor carpi radialis longus and brevis insertions, 4,5 conservative management has tended to require conversion to surgery due to diminished wrist strength or persistent pain caused by abrasion of the bony fragment. [6][7][8][9][10] We, therefore, advocate for a proactive approach to this injury.…”

Background Avulsion fracture of the extensor carpi ulnaris (ECU) bony insertion at fifth metacarpal base is a rare injury that may preclude recognition on radiographs. Case Description We report two cases of ECU avulsion fracture, both of which were successfully treated surgically by open reduction and fixation (ORIF). Literature Review Only two cases of ECU avulsion fracture have previously been reported in the literature. Forced motion of the wrist into a position of hyperflexion and/or radial deviation appears to be a common mechanism. Clinical Relevance Clinicians should be aware that ECU avulsion fractures can occur in isolation or in association with other fractures of the hand or wrist. ORIF is warranted due to the prospect of impaired wrist range of motion as well as persistent pain caused by the avulsed fragment.
