Do Circular Fixators Have a Role in Bone Tumor Management?

Description

The presentation by Sherif Ahmed Kamel discusses a study on the application of circular fixators in the treatment of bone tumors. Kamel introduces the concept of using advanced chemotherapy to facilitate limb salvage in tumor cases, highlighting the role of biological or metallurgical reconstruction. He proposes that circular fixators can be particularly beneficial for benign tumors or complications arising from conditions like Ollier disease, which necessitate limb lengthening or deformity correction.



The speaker outlines the methodology of the study conducted at Ain Shams University in Cairo, focusing on patients aged 5 to 60 who presented with significant bone defects or deformities. Kamel defines the inclusion and exclusion criteria for the study’s participants and emphasizes the multi-disciplinary approach taken in managing these patients, which included clinical assessments, histological confirmation of tumors, and the consideration of adjuvant chemotherapy.



Results from 15 cases are shared, noting a favorable MSDS score (measuring functional outcome) and significant improvement in the ASAMI score, which assesses limb reconstruction results. However, Kamel mentions some complications primarily linked to chemotherapy, particularly infections in cases where patients received treatment.



For malignant tumors, outcomes such as disease-free survival and overall survival rates are discussed, suggesting that while circular fixators are effective for benign and low-grade malignant cases, their use in high-grade malignancies carries risks due to chemotherapy and infection. Kamel concludes by underscoring the importance of multi-disciplinary management, effective communication, and patient adherence in achieving successful outcomes in limb reconstruction for bone tumors.
