Aims: Research was preformed including evaluation of early functional and radiographic results, six months after operative treatment of femoral neck fracture, using hemiarthroplasty and osteosynthesis, and late results, two years and more after operation. Methods: Clinical material comprehended two groups of hundred unselected patients each. Control exams included anamnestic data, and radiographic studies of treated hip. Data were stored in previously prepared research protocol according to applied functional and radiographic scoring systems. Results: Data were analized and compared between groups. Results of hip hemiarthroplasty showed direct influence of age, general state of health, size of prosthesis, use of cement and mode of rehabilitation on outcome of patients. Sex, social state, intercurrent diseases and length of operation showed no influence on outcome.
