We assumed that the intermediate fragment plays a decisive role for anatomic restoration of the trochlear notch and consecutive outcome of initial operative treatment. Methods 80 patients operated with diagnosis of complex olecranon fracture were identified in an 8-year-period from trauma unit files at two European Level 1 Trauma Centers. Retrospective review of all operative reports and radiographs computer-tomography scans identified patients with concomitance of an intermediate fragment. The Patient-Rated Elbow Evaluation Score was calculated for 45 of 80 patients at a minimum of 8 months postoperatively range 8-84 months . Results 29 patients were treated with stable internal fixation with figure-of-eight tension band wire fixation and 51 patients with posterior plate osteosynthesis with without intramedullary screw. An intermediate fragment was seen in 52 patients. In 29 of these 52 patients the intermediate fragment was described in operative report. 24 of these 29 patients were treated with posterior plate osteosynthesis and 5 patients with figure-of-eight tension band wiring. Complications included superficial infection 2 patients secondary dislocation 3 patients and heterotopic ossifications 1 patient . Functional outcome demonstrated a total PREE score of 9 points on average in 45 of 80 patients. Conclusion An extraordinary amount of patients showed an intermediate fragment. Consideration desimpaction and anatomic reduction of the .
