Osteoporose secundária com fraturas espontâneas de fêmur em paciente jovem associada à acidose tubular renal tipo 1: relato de caso

Abstract

This paper presents a case report of a young female patient who developed spontaneous bilateral femoral fractures secondary to Type 1 Renal Tubular Acidosis (RTA-1), a rare condition that affects renal function and disrupts the body’s acid-base balance. The patient, with no relevant traumatic history, experienced spontaneous fractures in both femurs, raising suspicion of an underlying condition. Investigation revealed that Type 1 Renal Tubular Acidosis was the cause of the fractures, due to the osteomalacia associated with the disease. The diagnosis was confirmed through laboratory and clinical tests, and the treatment included correction of the acid-base imbalance and orthopedic interventions for fracture management. The purpose of this paper is to report this rare case to the scientific community, emphasizing the importance of early diagnosis and appropriate management of uncommon clinical conditions such as RTA-1 to prevent serious complications and improve patient quality of life. The reported experience contributes to the understanding of the clinical manifestation of RTA-1 and may serve as a basis for managing similar cases.
