Osteoporosis Changes Collagen/Apatite Orientation and Young's Modulus in Vertebral Cortical Bone of Rat.

abstract：:We conducted a case-control study on fracture risk associated with the use of orally administered prednisolone/prednisone, budesonide, methylprednisolone, and hydrocortisone to assess if the various preparations were associated with different fracture patterns. Cases were all subjects with any fracture sustained durin...
