BackgroundX-linked hypophosphatemic osteomalacia (XLH) is an inherited disorder that can cause highly disabling musculoskeletal comorbidities in adulthood.ObjectiveTo analyze the clinical-radiological characteristics, comorbidities and complications associated with the disease and treatment in an adult population with XLH.MethodRetrospective study of patients treated for XLH in a rheumatology department in the last 10 years, evaluating the clinical-radiological findings, comorbidities and associated complications.ResultsFive patients between 39 and 75 years of age were included. All had short stature, osteoarticular symptoms and radiological enthesopathy. Four patients had early degenerative arthropathy of the knees and hips, and dental alterations associated with their disease. All patients older than 50 years required some type of prosthetic replacement. Two patients had femoral stress fractures, one had renal lithiasis and another developed tertiary hyperparathyroidism.ConclusionsMusculoskeletal manifestations are frequent and disabling in the adult population with XLH, so proper diagnosis and management from childhood are essential to prevent the development of complications in adulthood associated with this disease.Copyright © 2022 Elsevier España, S.L.U.
