| Abstract | 「はじめに」1971年Subramanianが99mTc標識のpolyphosphateを新しいBone seeking agentとして骨シンチスキャニングに応用して以来, 99mTcが半減期も適当に短く骨への被曝線量も少ないこともあってこの製剤による骨シンチスキャニング法が盛んになるすう勢にある. また, Bone seekerとしてより安定性のあるリン酸塩類の開発が行なわれ, 今日ではpolyphosphateの他にpyrophosphate, Diphosphonateなどが使用されだしており, これらの製剤もKit化され, 日常の骨疾患の診断に簡単に応用されている. 著者らは主として加令者を対象に日常の骨疾患の診断にpolyphosphate, pyrophosphate, Diphosphonateを使用し現在51例を数えるに至った. 今回は加令者の骨疾患に多い大腿骨頚部骨折の症例の中で興味ある骨シンチグラムを得たので報告する. 使用した全身スキャナー装置は島津のSCC-130Wに著者らと協同開発したミニスキャンを用い400cm/min. ピッチ3mm, 全身スキャンには約40分を要した. |

| Abstract | [Summary]Five cases with the fracture of femoral neck was found to have interesting finding in the bone scanning performed by 99mTc-labeled polyphosphate. These cases showed increased activity of radioisotope in the whole extremity of the side which had the fracture of femoral neck. Four cases were females, the age of whom ranged 57 yrs to 73 yrs. In three cases of them bone scanning were performed after operation of fracture (open reduction of femoral neck with fixation by nail plate, prosthetic replacement of femoral head). One case had osteoporosis with the fracture of bilateral femoral neck. One male case of fracture, he was not operated upon and only traction and wire fixation was performed, did not show such increased activity of the peripheral extremity of the side of fracture. This increased bone metabolism observed throughout extremity of the fractured side might relate with operation, however, one of two non-operated case also showed similar reaction throughout the extremity. Duration of such phenomena after fracture varies from 24 days to 9 months. Since the phenomena is so interesting that authors are now in the process to clarify the mechanisms behind, either neurogenic, mechanical, hemodynamic change or due to humoral factors. In summary, following fracture of femoral neck and its operation interesting enhancement of bone metabolism which extends from femur to lower extremity of the diseased side was observed in 4 cases among 5 such aged cases. Reasons are still left to be clarified. |
