Fig. 3

Bone cement filling without osteosynthesis after rigorous intralesional tumor resection. The large bone cement filling (arrow) can be easily depicted in plain radiographs (a) and MRI with T2-weighted sagittal series (b) and T1-weighted contrast-enhanced axial series (c). Although filling out the complete proximal humerus, sufficient stability was achieved without additional osteosynthesis as no postoperative fractures were found later on for all equally treated cases. Typical edema line (arrow in c) after bone cement implantation must be distinguished from local recurrence
