Abstract: Osteosarcoma is the most frequent malignant spinal tumour in the paediatric age group. Diagnosis and early treatment of this pathology is essential for a good prognosis. The aim of this study was to present the results of treatment of paediatric patients with lumbar osteosarcoma and conduct a literature review. All the patients with lumbar osteosarcoma who were operated between 2012 and 2014 in the same centre were included. Demographic and radiological data (Enneking, WBB and Tomita classification), as well as anatomopathological (Broders classification) variables were analysed. All the patients were treated by surgical resection associated with adjuvant therapies (chemotherapy and radiotherapy); according to consensus with the tumour committee. The average follow-up was 62.53 months (47-70 months). A total of 3 patients were studied, two girls of 9 and 11, with L5 osteosarcoma, and a 15-year-old boy with L4 osteosarcoma. Two of the cases were initially treated as an osteoblastoma, supported by radiological and anatomopathological images. None of the patients had local recurrences or metastases during follow-up. Due to a lack of long series of cases of osteosarcoma in the mobile spine during childhood, the optimal treatment and prognosis in these patients is uncertain. Block resection improves local control of the disease, without demonstrating improvement in overall survival. Intralesional resection is associated with a higher rate of local recurrence. Oncological treatment is essential in the treatment of this pathology. A correct differential diagnosis of the tumour (osteosarcoma vs. osteoblastoma) is vital for its correct treatment.
