Olecranon fractures are the most frequently seen fractures in daily orthopaedic traumatology practice. They consist approximately 10% of fractures around elbow and range from simple transvers fractures to complex fractured dislocations. Because all these fractures are intra-articular, majority are treated surgically. Surgical options are, tension-band wiring, plate fixation, intramedullary fixation, and triceps advancement after fragment excision. The treatment of olecranon fractures with an appropriate fixation and early mobilization create no problems. But it must be kept in mind that knowing the injury mechanism, the type of fracture and also well-known anatomy play an important role in preventing complications. Stiff elbow or arthritis is unavoidable unless a proper repair of the joint ensured.
