Fig. 4From: Enchondromas and atypical cartilaginous tumors at the proximal humerus treated with intralesional resection and bone cement filling with or without osteosynthesis: retrospective analysis of 42 cases with 6 years mean follow-upPainful large chondrogenic tumor at the proximal humerus prior to surgery with additional osteosynthesis. Plain radiograph (a) with typical popcorn-like calcifications (arrow) and T1-weighted axial MRI series (b) and T1-weighted contrast-enhanced coronal series (c) with endosteal scalloping (arrows) and reduced stability without significant differences compared to lesions treated without osteosynthesis (compare Fig. 1)Back to article page
