For this series of cN0 PTC patients: 1) SLNM accuracy was 97%, and 2) SLNM upstaging from cN0 to pN+ was 49%, whereas to stages III and IVa, it was 21%.
Background Bone grafts are widely used in orthopedic surgeries. Although the conventional iliac crest graft is still the largest source of cancellous and cortical-cancellous bone grafts, it may require a new surgical field and additional anesthesia. In contrast, the use of the distal radius graft allows removal in the same field; however, it is often the recipient site; thus, only a limited amount is usually available. In the upper limb, one of the possibilities is the use of the cancellous and/or cortical-cancellous graft from the olecranon. This was a primary and experimental study that aimed to analyze the versatility of using olecranon bone grafts through anatomical assessment of cadavers. Methods Eight upper limbs were dissected from four fresh, unclaimed, young cadavers, with no history of the previous pathology at the removal site to demonstrate the method of graft removal and to measure the quantity obtained in two situations, namely, removal of the cancellous graft and removal of the cortical-cancellous grafts. Results The average volume of the cancellous bone graft from the olecranon was 3.9 cm 3 (3.6 to 4.2 cm 3 ). The cortical-cancellous bone graft had an average length of 4.4 cm (4.1 to 5.0), a width of 0.8 cm (0.7 to 1.0), and an average thickness of 0.4 cm (0.3 to 0.6). Conclusion The technique for harvesting the olecranon graft is easy to perform, allowing a volume in average 3.9 cm 3 of cancellous graft and 4.4 cm and 0.8 cm of cortical-cancellous bone, for various upper limb defects, which require this need.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
