This study aims to evaluate the diverse etiology, diagnostic challenges, and treatment options for pediatric osteoporosis in a cohort of affected children. Methods: We reviewed eleven pediatric patients (aged 5\u201316 years) diagnosed with vertebral fractures and osteoporosis, who were hospitalized between 2020 and 2024 at the Department of Endocrinology and Metabolic Diseases at PMMH-RI in Lodz. Clinical evaluation included medical history, physical examination, biochemical markers of bone metabolism, and imaging techniques such as dual-energy X-ray absorptiometry (DXA) to determine underlying causes of bone fragility. Results: The cohort presented a broad etiological spectrum, including seven patients with genetic disorders (e.g., mutations in COL1A1, LRP5, SGMS2, and ALPL genes) and secondary osteoporosis due to chronic diseases requiring prolonged glucocorticoid therapy (two patients with Duchenne muscular dystrophy (DMD), one patient with Crohn\u2019s disease) or endocrinological disorders (one patient with Cushing disease). Vertebral fractures were confirmed in all patients, with back pain as the predominant symptom. Low bone mass (BMD Z-score &lt; \u22122.0) was observed in eight individuals; in others, clinical signs of skeletal fragility were present despite Z-scores above this threshold. Mild biochemical abnormalities included hypercalciuria (3\/11 cases) and vitamin D deficiency (6\/11 cases). Height adjustment improved BMD interpretation in short-stature patients. Most children received bisphosphonate therapy, supplemented with calcium and vitamin D. In two patients, bisphosphonates were not used due to lack of parental consent or underlying conditions in which such treatment is not recommended. Conclusions: Pediatric osteoporosis requires a multidisciplinary diagnostic and therapeutic approach, integrating clinical, biochemical, and genetic factors. It is a heterogeneous and often underrecognized condition, with vertebral fractures frequently serving as its earliest sign\u2014even in the absence of overt symptoms or low bone mass. This underscores the need for clinical vigilance, as significant skeletal fragility may occur despite normal BMD values. Importantly, pediatric osteoporosis may also impact the attainment of peak bone mass and ultimately affect final adult height. Early diagnosis through thorough assessment, including height-adjusted DXA, and a multidisciplinary approach are essential to ensure timely management and prevent long-term complications.<\/jats:p>","DOI":"10.3390\/jcm15010123","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T09:58:34Z","timestamp":1766570314000},"page":"123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Spectrum of Osteoporosis Etiologies with Associated Vertebral Compression Fractures in Children: Analysis of 11 Cases"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-9168-0192","authenticated-orcid":false,"given":"Sara","family":"Aszkie\u0142owicz","sequence":"first","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6697-5877","authenticated-orcid":false,"given":"Anna","family":"\u0141upi\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 93-338 Lodz, Poland"},{"name":"Department of Developmental Age and Adult Endocrinology, Medical University of Lodz, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6878-3388","authenticated-orcid":false,"given":"Izabela","family":"Micha\u0142us","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2941-8868","authenticated-orcid":false,"given":"Arkadiusz","family":"Zygmunt","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 93-338 Lodz, Poland"},{"name":"Department of Developmental Age and Adult Endocrinology, Medical University of Lodz, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0508-2186","authenticated-orcid":false,"given":"Renata","family":"Stawerska","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital\u2014Research Institute, 93-338 Lodz, Poland"},{"name":"Department of Developmental Age and Adult Endocrinology, Medical University of Lodz, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1016\/j.jocd.2014.01.003","article-title":"Dual-Energy X-Ray Absorptiometry Interpretation and Reporting in Children and Adolescents: The Revised 2013 ISCD Pediatric Official Positions","volume":"17","author":"Crabtree","year":"2014","journal-title":"J.
