Modern applications of 3D technologies for the treatment of bone tissue defects

The use of 3D technologies offers more precise planning of surgical procedures in complex cases of localized bone tissue deficiency, allowing adaptation to individual anatomical features, improved outcomes, reduced risk of complications, and faster postoperative recovery. To analyze the current capabilities of three-dimensional printing in the surgical management of pelvic and hip bone defects, we reviewed scientific literature available in open-access databases including PubMed, eLibrary.Ru, Scopus, and Dimensions, with a search depth of up to 10 years. This review highlights major trends and advances in the medical application of 3D technologies aimed at reducing perioperative risks and improving patients’ quality of life in the context of bone tissue defects. Particular focus is placed on revision hip arthroplasty and pelvic oncologic conditions, where modern additive manufacturing technologies can enhance treatment quality and surgical outcomes. The methodology of 3D scanning for designing patient-specific implants is described. The review also demonstrates current and promising applications of 3D printing in clinical practice. Modern 3D technologies, particularly additive manufacturing, play an important role in improving surgical outcomes for skeletal deficiencies by enabling personalized treatment, expediting recovery, and improving patient prognosis. Emerging directions significantly expand the range of available reconstructive procedures, reduce the risk of complications, and ultimately improve patient quality of life and surgical efficiency.
