Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Bone can be the site of primary malignant tumors or, more commonly, secondary lesions. The most frequent primary tumors are osteosarcoma, chondrosarcoma, and Ewing sarcoma, whereas the malignancies that most commonly metastasize to bone include breast, prostate, lung, kidney, and thyroid cancers.
For the treatment of these conditions-and, in some cases, for locally aggressive benign diseases-a surgical approach is often required, which may result in substantial bone loss. Most commercially available prostheses commonly used in orthopedic surgery are not always suitable, either because of the anatomical location of the procedure or the type of resection planned, and thus the extent of the bone defect to be reconstructed. Therefore, specific prosthetic implants designed for oncologic surgery are required.
For this reason, modular prostheses have been developed, allowing reconstruction of bone defects of varying sizes across different anatomical districts. In recent years, the development and use of 3D-printing technology for producing custom-made prostheses has also increased, with the aim of reconstructing bone defects in areas that are difficult to treat and achieving an accurate reproduction of the patient's anatomy. This technology enables reconstruction in a wide range of skeletal sites. Additionally, it allows for preoperative planning on printed anatomical models and opens the possibility of integrating materials with adjuvant-related properties into the prosthetic design, such as photothermal therapy or antimicrobial features.
Although numerous studies on this topic are available in the literature, they frequently involve small patient cohorts. There is therefore a need to expand case series with longer follow-ups to better assess the reliability and effectiveness of these treatment strategies in the development of reconstructive orthopedic oncologic surgery.
