The Difference

Summary Aim: The aim of this study was to evaluate the normal distribution of sodium fluoride-18 (NaF-18) and to clarify the differences in uptake according to location and the type of the bone using positron emission tomography (PET) / computed tomography (CT). Methods: We retrospectively reviewed NaF-18 PET/CT images from 30 patients with hip joint disorders. PET/CT scans were performed 40 min after injection of approximately 185 MBq of NaF-18. To evaluate the relationship between the distribution of NaF-18 uptake and bone density, we compared the maximum standardised uptake values (SUVmax) on PET and the Hounsfield Units (HUs) on CT of the lumbar vertebra, ilium, and proximal and distal femurs. Regions of interests were defined both outside and inside the cortical bone to measure whole bone and cancellous bone only, respectively. Results: The distribution of NaF-18 differed according to the skeletal site. The lumbar vertebra showed the highest SUVmax for both whole bone and cancellous bone, followed by the ilium, proximal femur, and distal femur. The bones differed significantly in SUVmax. The distal femur showed the highest HU, followed by the proximal femur, ilium, and vertebra. Profile curve analyses demonstrated that the cancellous bones showed higher SUVmax and lower HU than the cortical bones. Conclusions: Our results demonstrate the difference in NaF-18 uptake between cancellous and cortical bones, which may explain differences in uptake by location. NaF-18 uptake does not appear to be strongly correlated with bone density, but rather with bone turnover and blood flow.

To quantify the amount of cancellous bone graft available from the greater trochanteric region, 20 paired iliac crest-proximal femur specimens were harvested and compared in 10 adult pelvises. A 1.3 × 1.3-cm cortical window was made in the lateral aspect of the proximal femur 2 cm distal from the tip of the greater trochanter. Cancellous bone evacuation was performed by curettage. The extent of harvest was mechanically limited by the medial wall of the trochanter and by curette impingement on the margins of the cortical window. The graft was quantitated after maximal digital compression in a 10-ml syringe and compared with cancellous graft obtained from the paired anterior iliac crest. The average compressed volume of cancellous bone harvested from the greater trochanter was 6.5 ml (range, 4.2–9.6 ml). The average iliac crest cancellous bone volume was 6.0 ml (range, 2.7–8.8 ml). Differences in graft volume between the anterior iliac crest and the trochanter were not statistically significant. The resulting defect in the proximal femur remained isolated to the trochanteric region. In this study, we demonstrate that cancellous bone is available from the greater trochanteric region in an amount similar to that available from the anterior iliac crest. We also show that it is obtainable in a reproducible manner. Our clinical experience of over 100 cases has demonstrated acceptable morbidity associated with this technique. The greater trochanteric region may be used as a secondary source of autogenous cancellous bone graft when specific procedures demand more bone graft than available from the iliac crest alone, or in patients who have had previous iliac crest graft harvest.
