The bipolar Hemiarthroplasty Using the Porous - coated Femoral stem in Avascular Necrosis of the Femoral Head
Abstract
- The authors reviewed both the clinical and radiographic results of 36 bipolar hemiarthroplasty using the porous-coated Harris-Galante uncemented femoral stem performed for avascular necrosis in 30 patients from January 1985 to June 1992. The average age was about 45.6 years and the average follow-up was fifty-four months. Clinical results by the Harris evaluation method were excellent in 33 cases, good in 2 cases, and fair in 1 case. The radiographic fixation of the femoral stem at final follow-up was bony ingrowth fixation in 31 cases, fibrous ingrowth fixation in 4 cases, and unstable fixation in 1 case. There was neither medial nor superior migration of the bipolar cup of more than two millimeters.
