Hemiarthroplasty performed with Ultrahigh Molecular Weight Polyethylene Liner Composite in a 10 Years Old Child having Osteosarcoma of the Proximal Tibia: A Case Report / 대한정형외과학회잡지

ABSTRACT

The proximal tibia is the second most common site for primary malignant bone tumors. With the progression of chemotherapy and surgical technique, limb salvage is being accepted as a generalized procedure, even in growing child. But for those children, especially around 10 years, who still have a considerable growth potential, it is difficult to selecting the appropriate prosthesis, except for cases with arthrodesis, and arthroplasty is an unreasonable procedure in many cases. We tried to maintain the mobile joint along with minimal complications, and we designed the hemiarthroplastic technique using the ultrahigh molecular weight polyethylene (UHMWPE) liner, intramedullary nail, bone cement and low heat treated autograft composite. This article present the results of 52 months follow up on this surgical procedure.
