BMD and T-scores. Four patients (2 with MS and 2 with HSP/HA) had hip replacements in the left hip and DXA was performed on the right side. Three patients did not have DXA measurements of either hip (1 MS patient with bilateral hip implants and 2 HSP/HA patient with either bilateral hip implants or implant in right hip and rotation osteotomia of the left hip), thus findings in hips only include 90 MS patients and 75 controls
