Abstract

|
|
Purpose: The proximal tibial sarcoma patients, especially in their growing ages have problems of reconstruction. This study is to devise a methodology which can circumvent this limitations.
Materials and Methods: Four cases of proximal tibial osteosarcoma underwent hemiarthroplasty. The mean age was 13 years (11~15) with a mean follow-up of 64 months (47~89). The procedure consists of ultrahigh molecular weight polyethylene (UHMWPE) liner as an substitute for the joint surface and this piece was fixed to the remaining tibial bone stock with Ender nail and bone cement.
Results: Final functional score was 23.5 (78.3% of control) by MSTS criteria. All the cases showed stable joint without pain. Hemiarthroplasty related complications were absent. By saving the femoral physis, expected leg length discrepancy could be minimized by this procedure.
Conclusions: Hemiarthroplasty of proximal tibia can be an option in pediatric sarcoma patients.
