BMD could be improved by parathyroidectomy. Both BMD in the lumbar and the femur and SOS in the tibia may reflect the loss of bone mass, their combined use may early and more sensitively detect the skeletal disorders in the patients with PHPT.

• DXA测定的腰椎和股骨上端BMD及骨超声仪测定胫骨SOS均可反映PHPT患者的骨量丢失,联合测定胫骨SOS值可能有利于更早、更灵敏地发现PHPT患者骨骼系统的病变。
