Abstract:

BACKGROUND: With the maturity and development of artificial joint materials, processes and technology, artificial femoral head replacement has been widely used for the treatment of femoral neck fracture, especially the elderly patients with displaced femoral neck fracture. 
OBJECTIVE: To observe the clinical efficacy of biotypes and cementless artificial femoral head replacement for the treatment of elderly femoral neck fracture combined with heart disease.  
METHODS: Thirty-five elderly femoral neck fracture patients with heart disease treated in the Department of Orthopedic Center, Tianjin Nursing Home from January 2004 to December 2009 were selected, including 16 cases of coronary heart disease combined with angina pectoris, eight cases of myocardial infarction coronary heart disease, eight cases of asymptomatic coronary heart disease and three cases of ischemic cardiomyopathy and coronary heart disease. And 18 cases were treated with biotypes artificial femoral head replacement, 17 cases were treated with cementless artificial femoral head replacement.
RESULTS AND CONCLUSION: One of the 35 patients was dead in the surgery, other 34 cases were followed-up for 8 to 36 months. Three cases of complications occurred in surgery were belongs to cementless group, and one patient died during surgery, two cases had to drop in blood pressure and suffered from difficulty breathing in surgery, whose life characteristics returned to normal after efforts to save. In the follow-up process, part of the prosthesis implanted in the two cases of patients with severe osteoporosis appears sinking in the biotype group, the excellent rate of biotype group was 89%(16/18), and the cementless group was 94%(16/17). It suggests that biotype artificial femoral head replacement is suitable for the patients with severe heart disease, while the cementless artificial femoral head replacement is suitable for osteoporosis patients.
