| Abstract | 「要旨」手関節舟状骨骨折36例, 37関節を治癒過程群と偽関節群に分類し三相 (3フェーズ) 骨シンチグラフィ (3相骨シンチ) を行い検討した. 血流相では, 治癒過程群は有効であった装具固定に伴う良好な経過を反映して, 橈骨動脈の血流亢進と灌流増加が認められた. 一方プール像では, 受傷後7日以降には局所の修復の活動性と有効性を反映した放射能集積があり, 経過良好例には集積亢進が, また治癒期には集積低下が顕著であった. このためプール像には後期像以上の有用性が認められた. 舟状骨全体の高度な集積亢進は経過良好例の, そして近位骨片の集積低下は偽関節例のそれぞれ典型的な所見であった. 3相骨シンチは手関節舟状骨骨折の病勢と予後の判定, 治療経過の判定に有用である. |

| Abstract | [Summary] Thirty-seven joints in 36 patients with a fractured carpal scaphoid were evaluated by three-phase bone scintigraphy. They were classified into two groups according to their progress. Some were in good clinical condition and some in a non-union condition. Increased blood flow in the radial arteries and ample perfusion on and around the scaphoid bones on blood flow images suggested a good clinical course. The activity and the effectiveness of remodeling correlated well with the degree of scaphoid uptake on blood pool images taken more than seven days after the injury. Scaphoid uptake was more localized or there was almost none on blood pool images in cases with nearly complete recovery while it was amply visualized on static images. Blood pool images were indispensable for analyzing lesions and evaluating the clinical course. Two typical findings of scaphoid fractures were found on both blood pool and static images. One was diffusely increased scaphoid uptake seen in cases with a good clinical course, and the other was decreased uptake at proximal fragments seen in cases with non-union. It is concluded that three-phase bone scintigraphy provides useful information for evaluating the process of scaphoid fractures which cannot be obtained by means of conventional bone scintigraphy. |
