Anti-platelet drugs in patients with femoral neck fractures undergoing cemented hip hemiarthroplasty surgery. A study of complications and mortality.

OBJECTIVE To assess complications and factors predicting one-year mortality in patients on antiplatelet agents presenting with femoral neck fractures undergoing hip hemiarthroplasty surgery. MATERIAL AND METHODS A review was made on 50 patients on preoperative antiplatelet agents and 83 patients without preoperative antiplatelet agents. Patients in both groups were treated with cemented hip hemiarthroplasty. A statistical comparison was performed using epidemiological data, comorbidities, mental state, complications and mortality. There was no lost to follow-up. RESULTS The one-year mortality was 20.3%. In patients without preoperative antiplatelet agents it was 14.4% and in patients with preoperative antiplatelet agents was 30%. Age, ASA grade, number of comorbidities and antiplatelet agent therapy were predictors of one-year mortality. The one-year mortality of patients on clopidogrel was 46.1%, versus 24.3% in patients on acetylsalicylic acid. CONCLUSION Patients with preoperative antiplatelet therapy were older and had greater number of comorbidities, ASA grade, delayed surgery, and a longer length of stay than patients without antiplatelet therapy. The one-year mortality was higher in patients with preoperative antiplatelet therapy.
