Olecranon fractures are common injuries of the proximal ulna following low energy trauma. The aim of fracture treatment is to restore early, active, elbow motion and function. In the current study twenty patients twelve males and eight females with different patterns of fracture olecranon have been include. Patients were identified according to type of fixation five methods were used in this study: Tension band with K-wire placed in intramedullary canal, tension band with K-wire placed in anterior ulnar cortex, tension band with intramedullary screw, posterior contoured reconstruction plate and posterior contoured one –third tubular plate. They all had pre and post-operative x-rays and were followed up in outpatient clinic. It was conclude that two K-wires placed in anterior ulnar cortex with tension band is recommended for all transverse fractures, while posterior recon. Plate is recommended for comminuted and unstable oblique fractures.
