Intertrochanteric fractures are a major cause of mortality and morbidity in the elderly. Require if possible surgical management. It has not been defined yet whether to treat with osteosynthesis or the hip arthroplasty.. For this reason we decided to conduct a study identifying the results in each of the treatments with Colombian population in the Mayor Mederi University Hospital. Methods: Retrospective descriptive observational study, series of cases. A cohort of over 59 years old patients with intertrochanteric fracture where analyzed at the Mayor Mederi University Hospital Results: A total of 179 cases were reported with a diagnosis of intertrochanteric fracture. The total mortality was 11 patients which correspond to 6.1% of the sample,; 7 patients underwent osteosynthesis and the remaining 4 underwent hemiarthroplasty. 7 infections were registered in total which occurred respectively in 6 osteosynthesis and 1 hemiarthroplasty. Discussion: registered mortality was higher in the osteosynthesis procedures with a total of 7 patients dead equivalent to 63.6% of total study, reaching a statistical significant difference. Postoperative infection rates were significantly higher in osteosynthesis finding that from the total of patients operated 3.9% became infected among which 85.7% were osteosynthesis and 14.3% corresponded to hemiarthroplasty. Postoperative bleeding increased to 500 cc, which mean 39% of osteosynthesis and 44 % in the hemiarthroplasty. Conclusion: The treatment of intertrochanteric fractures at the Mayor Mederi University Hospital had a lower mortality and a lower infection rate when patients were treated with hemiarthroplasty or total hip replacement. Surgical times were similar in the 3 types of treatment.
