Elderly males with or without existing osteoporotic vertebral fracture have much lower future vertebral fracture risk than elderly females: the MrOS (Hong Kong) year-4 follow-up spine radiograph study

MrOS (Hong Kong)’s year-4 follow-up shows, for subjects at baseline without vertebral deformity (VD) and endplate or/and cortex fracture (ECF), the VD progression/new VD rate during follow-up in males was half of our paired MsOS (Hong Kong) study’s results. For those with VD or ECF, the VD progression/new VD was less than one sixth of females’ rate. This study documents MrOS (Hong Kong)’s year-4 follow-up, and the results are compared with the...
