Dual-energy X-ray absorbtiometry to evaluate periprosthetic bone mineral density around an uncemented stem implanted using either lateral or anterolateral approach to the hip joint	Other	The measurement will start in the area about 2 cm proximal to the greater trochanter and will stop slightly below the tip of the prosthesis. This is the baseline scan and will be carried out twice with the patient lying on the table, but with movement between each scan. This is done to calculate the CV, Coefficient of Variation. We will use the formula from Wilkinson and associates, where delta is standard deviations (SD) of the difference between the two BMD measurements for each patient. BMD has been measured at baseline, 3 and 12 months. A DXA scan is now planned at 60 months. Changes in BMD related to the 7 Gruen zones will be registered.
