Precocious Idiopathic Primary Osteoporosis in Men: A Case Report

Osteoporosis is a metabolic-based bone disease, which is one of the most frequent osteoarticular comorbidities, especially in countries with older populations, and is associated with an elevated risk of bone fractures with significant morbidity and mortality. We present a case of a 58-year-old man seen at a Primary Care facility complaining of acute low back pain. After persistence of the complaints for 3 weeks, an imaging study with lumbar computed tomography (CT) was performed, showing multiple fractures and rarefaction of bone trabeculation. The diagnosis of osteoporosis was confirmed after bone densitometry with a Z-score of -3.3 in the lumbar spine. The main secondary causes of osteoporosis have been excluded, and no family history is known. The only risk factor found was smoking (37 UMA). The patient was treated with denosumab and cholecalciferol + calcium carbonate. Assessment was requested at a Rheumatology hospital consultation and is now undergoing additional genetic study and monitoring of the disease.
