Abstract
Purpose
We evaluated the clinical and radiographic outcomes of cementless bipolar hemiarthroplasty using rectangular cross-section stem for femoral neck fracture in elderly patients more than 80 years of age with osteoporosis.
Material and Methods
76(cemented 46, cementless 30) bipolar hemiarthroplasties for femur neck fracture were performed in elderly patients more than 80 years old. The mean follow-up period was 4.3 years (2 to 7 years). The Harris hip score at last follow-up and pre-postoperative daily living activity scale according to Kitamura methods were analyzed clinically. The radiological results were assessed using stability of femoral stem and other complications were evaluated. Results: At last follow-up, there were no significant differences of Harris hip score and daily living activity between two groups. Stem loosening and instability were not observed in cementless arthroplasty. There were 18 cases of osseous fixation in radiologic study. There were 1 case of dislocation and 1 case of superficial infection in cemented arthroplasty and 1 case of deep infection in cementless arthroplasty.
Conclusion
Cementless bipolar hemiarthroplasty using rectangular cross-section stem for elderly patients with a femoral neck fracture showed satisfactory short-term clinical and radiological results compared to using cement stem.
