The incidence of the olecranon fracture (OF) in adults is around 12 per 100,000 inhabitants per year.1 The anatomical shape of the proximal ulna is largely responsible for the stabilization of the humeroulnar joint and reconstruction is therefore obligatory, but often challenging. Surgical treatment of the olecranon fracture is performed using tension band wiring (TBW) or locking plate fixation (LPF) osteosynthesis. It is not yet clear, which procedure is superior for a specific patient. In future, an individualized and objectified assessment of expected general and fracture-specific complications should enable the treatment to be individually adapted to the patient\'s risk profile. This shall prevent complications, unnecessary treatments, and treatment costs. In the project presented here, the reality of care for surgically treated patients with olecranon fractures will be analyzed using routine data collected by the BARMER health insurance fund. The aim of the study is to analyze differences in the outcome of patients with an olecranon fracture treated with TBW compared to LPF and to identify independent risk factors for unfavorable course.

Revision
Time from surgery to revision defined above.
Time frame: up to 5 years
Implant removal (only)
* Time from surgery to implant removal * Within first 3 months after surgery, an implant removal will also considered as a surgical complication * No SC is allowed to occur within 3 months and on the same day
Time frame: up to 5 years
Surgical complications (surgical complications)
Time from surgery of olecranon fracture to surgical complications, with death being considered as a competing risk event.
Time frame: up to 5 years
In-hospital surgical complication rate (IH-SC)
surgical complication after surgery during index hospitalization (yes/no)
Time frame: through hospital stay, an average of 10 days
In-hospital implant-associated complications (IH-IAC)
In-hospital implant-associated complications after surgery during index hospitalization
Time frame: through hospital stay, an average of 10 days
In-hospital non-implant associated complications (IH-non-IAC)
Non-in-hospital implant-associated complications after surgery during index hospitalizationi
Time frame: through hospital stay, an average of 10 days
Overall survival (OS)
* Time from surgery to death of any cause. * Death will be determined using the coded death as the reason for withdrawal in the BARMER database. In addition, all inpatient cases will be reviewed during follow-up, to determine whether death was reported as the reason for discharge.
Time frame: up to 5 years
30-day mortality
* Death from any cause within first day after surgery (yes/no) * All patients with shorter follow-up time are excluded
Time frame: 30 days
Major adverse events (MAE)
Time from surgery to resuscitation, cardiac arrest, myocardial infarction, stroke, acute renal failure, acute liver failure, acute respiratory distress syndrome, sepsis or death from any case.
Time frame: up to 5 years
Thromboembolic events
Time from surgery to a thromboembolic event or death of any cause.
Time frame: up to five years
Minor outpatient complication
Time from discharge to minor outpatient complications, with death being considered as a competing risk event.
Time frame: up to five years
Length of hospital stay during index
Days of hospitalization (from admission to last discharge with index case series)
Time frame: an average of 10 days
Charges during index
Sum of charges of all cases of the index case series
Time frame: an average of 10 days
