Abstract

Dedifferentiated chondrosarcomas are aggressive, malignant tumors characterized by growth potential and a lytic soft tissue component.Radical resection is the recommended treatment protocol, but can be difficult depending on anatomic involvement and location of each tumor. We describe a modification of the Tikhoff-Linberg procedure for resections in the shoulder girdle, in which a scapulectomy is performedwithout resection of the proximal humerus, and extensive skeletal and soft tissue reconstruction is utilized to maintain adequate functional and aesthetic outcome.
