Read Original Article Here July 12, 2013 After hip resurfacing, bone mineral density continued to positively change up to 5 years, primarily in the trochanteric and superior neck regions, according to recent medical study… …(the)femoral component size has a significant role to play in the change in [bone mineral density] BMD up to 5 years… …”The greater the acetabular inclination, the greater the increase in trochanteric area BMD at 5 years…A valgus position of the femoral component leads to a significantly greater increase in the BMD both in the superior femoral neck region and trochanteric area at 5 years. Researchers prospectively studied BMD change in 31 patients with a Birmingham Hip Resurfacing (Smith & Nephew; Memphis, Tenn.) system. At 5-year follow-up, data were available for 26 patients. BMD had decreased by up to 10% in the trochanteric and superior neck regions at 6 weeks and 3 months after surgery before recovering to preoperative levels by 1 year…
