Fig. 5From: High periprosthetic bone mineral density measured in immediate postoperative period may not guarantee less periprosthetic bone loss in the proximal femur after cementless total hip arthroplasty – A retrospective studyThe BMD of Gruen zone 7 (a) and 1 (b) measured 1 week after surgery were also analyzed for the value as a predictor for BMD changes of Gruen zone 7 and 1 in the first postoperative year by using a multiple linear model with the calculation of the coefficients of determination (R2), respectively. Other variables enrolled in the multiple linear analysis included sex, age, BMI, primary diagnosis, and preoperative BMD of hip/spineBack to article page
