What can be concluded on the basis of the bone scan in regards to the distal femoral lesion?
Overall impression is that the left lower femoral lesion is metabolically inactive or only minimally active.
Initial blood flow studies of the knees and thighs show slightly increased vascularity at the left upper femur. Delayed whole body study and multiple views of the femur show an intense increase in tracer uptake at the upper end of the left femoral shaft particularly at the lesser trochanter. This is consistent with the recent fracture though the intensity at the lesser trochanter appears excessive (? delayed union).
In the lower femoral shaft the supracondylar region (distinct from the screw induced cortical lesions) only a minor increase in tracer uptake is noted consistent with a metabolically inactive lesion.
Elsewhere there is evidence of mild spondylosis at the right side of the lower lumbar spine and the right T7 and T8 consistent with spondylosis. The left renal upper half cortical filling defect is noted presumably a cyst but other lesions cannot be excluded. Minor increases in tracer uptake are noted at the acromioclavicular joints consistent with osteoarthritis there or underlying supraspinatus tendinitis.
