Abstract:
Over the past decade, significant progress has been made in pediatric bone tumor lower limb lengthening techniques, with Ilizarov stretching osteogenesis as the fundamental foundation. Individualized traction adjustments facilitate efficient bone regeneration. While external fixation devices, such as Ilizarov circular frames and unilateral braces, offer user-friendly convenience, they often entail prolonged treatment durations and a myriad of associated complications. In cases with specific parameters, such as bone defects <5 cm, epiphyseal growth modulation techniques present viable therapeutic avenues. Lengthening prostheses can be employed, particularly for substantial bone defects, leveraging minimally invasive and non-invasive designs to mitigate complications. There remains a pressing need to enhance materials and structural integrity effectively combat infections and mechanical failures. Intramedullary lengthening nails, exemplified by the Precice nail, boast high comfort and a low infection risk, yet effective complication management remains critical. Contemporary treatment paradigms prioritize individualized treatment plans, aiming to curtail treatment durations and complications through material enhancements and refined fixation methodologies. The forthcoming evolution and cost-effectiveness of domestically manufactured bone lengthening technologies represent pivotal realms of scholarly inquiry and practical application, with the overarching objective of ameliorating the quality of life for children contending with limb length discrepancies post bone tumor surgery while simultaneously diminishing complication rates.
