１８例慢性肾衰继发性甲旁亢病人发现有锁骨骨吸收。发病部位包括锁骨内端、外端、外１／３下缘及内段下缘４个部位。其中锁骨内、外端骨吸收属软骨下骨吸收，内、外段下缘骨吸收属韧带下骨吸收。作者对锁骨骨吸收的Ｘ线表现及发病机制作了讨论。认为锁骨骨吸收是继发性甲旁亢的重要Ｘ线征象，对诊断肾性骨病具有重要的意义。 18 cases of chronic renal failure secondary hyperparathyroidism patients found clavicular bone resorption. Including the internal parts of the incidence of clavicle end, outer end, outer 1/3 lower edge and the inner edge of the lower four parts. One of the clavicle, the outer end of bone absorption is a subchondral bone absorption, the lower edge of bone absorption under the bone is under the bone absorption. The authors discuss the X-ray findings and pathogenesis of clavicular bone resorption. It is considered that the absorption of clavicle bone is an important X-ray sign of secondary hyperparathyroidism, which is of great significance for the diagnosis of renal osteodystrophy.
