Fourteeen domestic pigeons (Columba livia) weighing 290 to 420g, were submitted to open reduction of humeral diaphysis fracture with external fixator type Ia (unilateral-uniplanar) in order to evaluate the clinical, histological and radiographic evolution of the bone healing. The external fixator device was stabilized with methilmetacrylate acrylic. The average time necessary to the complete disappearance of the fracture line by radiographic evaluation was 28±6.44 days. The bone callus was identified at 17±3.26 postoperative days. The birds returned to flying in 28±1.2 days yet with the fixation device and only one did not recovere the flying abillity. The external fixation technique is an efficient method to treat diaphiseal humeral fracture in domestic pigeons.
