Late bone scintigraphy of a a patient (number 1) treated with autologous bone, b a patient (number 7) treated with autologous bone and OP-1, and c a patient (number 13) treated with allogenic bone and OP-1 24 months following operation. Higher uptake of 99mTc is present in surgically treated scaphoids (arrow), compared with opposite healthy hand (h). Increased vascular spaces in OP-1-treated patients (b, c) 24 months following operation indicate its permanent presence. 3D reconstruction of CT scans of d patient number 1, e patient number 7, and f patient number 13 24 months following operation. Minimal amounts of sclerotic bone (OS) are present in the proximal pole of patient number 7
