TREATMENT OPTIONS FOR GIANT-CELL TUMOR
B. Tomeno | MO n°136
August 2004 |  This decision has been carefully thought through : as a giant-cell tumor can be benign or malignant, an in-depth study of GCT provides the essence of what one needs to know about tumors and their variants, as well as the technical tricks regarding curettage & bone-grafting which is the classical treatment for all benign intraosseous tumors. An overview of the malignant forms of GCT gives an idea of the resection-reconstruction techniques and associated therapies (radiation therapy and chemotherapy). GCT is an ideal "model" for educational purposes. Giant cell tumor is a frequent occurrence. It accounts for 15 to 20% of all bone tumors. However, its histogenesis remains unclear (it is thought to originate from connective tissue precursor cells). GCT is mostly found in the limbs (90%) and sometimes in the trunk. The giant cell tumors described ...

Vascularised fibular graft after surgical resection of bone tumours in the growing child
R. Capanna M. Innocenti M. Ceruso P. Caldora Da Campanacci G. BeltramiB. Gluckert | MO n°64
May 1997 | The greatest problem with limb reconstruction after resection of bone tumours in children is the loss of potential growth from the resected articular part, with the consequent risk of residual limb-length discrepancy.A vascularised fibular autograft complete with its growth plate may be used to replace the resected metaphysis with a viable bone segment which is able to grow over time, as well as restoring the anatomy and function of the joint.For mechanical and anatomical reasons, vascularised fibular grafts in growing children are only indicated in cases of defects (loss of substance) of the upper limb.The low mechanical strength of the graft makes it more suitable for an anatomical region which is not subject to load-bearing, and the fibular epiphysis is able to replace the proximal humerus or the distal radius of the immature skeleton, ...
