Abstract
Periprosthetic bone loss is a well documented phenomenon after cementless total hip arthroplasty. We compared the bone mineral density (BMD) in 33 patients using the three dimension taper shape stem and 13 patients with a straight component with a distal taper. Postoperative follow-up was evaluated by dual-energy X-ray absorptiometry. BMD was recorded in seven Gruen zones. BMD was correlated with clinical examination, Harris Hip Score (HHS), Body Mass Index (BMI) and age. Clinical assessment took place at 12 months post operation. Periprosthetic BMD loss using the three dimensional straight tapered stem was consistently much less in comparison with the straight type component with a distal tapered design stem. BMD in Gruen zone 1 was maintained. There was no correlation between periprosthetic bone mineral density and clinical factors.
