Displaced olecranon fractures disrupt the extensor mechanism of the elbow and operative treatment is therefore usually recommended. Tension band wiring (TBW) and plate fixation (PF) are the most common surgical treatment options. Both methods are associated with high complication and reoperation rates, especially in elderly patients. Only one randomized controlled trial has compared operative and non-operative treatment of olecranon fractures in the elderly, but the study was stopped prematurely due to high complication rates in the group treated operatively and remained underpowered for important outcome measures.A few small patient series with non-operatively treated fractures also exist and suggest that it may be a valid alternative to operative treatment
Operative treatment, with tension band wiring or plate fixation, will be compared with non-operative treatment of displaced olecranon fractures (Mayo classification 2A and 2B) in patients 75 years or older.
