Idiopathic chondrolysis of the hip is a rare condition of unknown etiology characterized by progressive destruction of the hyaline cartilage that covers the femoral head and acetabulum. Idiopathic chondrolysis of the hip has an insidious beginning and affects more often female adolescents. Patients report severe hip pain, mobility limitation, and even claudication. This study aimed at reporting one case of that rare disease: an 11-year-old female adolescent with chondrolysis, followed up for three years. Inflammatory activity tests were normal. Imaging tests (radiography, ultrasonography and magnetic resonance) were essential for the diagnosis. The treatment was based on pain control and preservation of the joint mobility, and included low-impact physical activity, non-steroidal anti-inflammatory drugs, and disease-modifying antirheumatic drugs, with good response after 12 months of treatment. Surgery was not necessary.
髋关节特发性软骨溶解是一种病因不明的罕见病症，其特征是覆盖股骨头和髋臼的透明软骨进行性破坏。髋关节特发性软骨溶解起病隐匿，更常影响女性青少年。患者报告有严重的髋关节疼痛、活动受限，甚至跛行。本研究旨在报告一例该罕见疾病：一名11岁患有软骨溶解的女性青少年，随访三年。炎症活动测试结果正常。影像学检查（X线摄影、超声和磁共振成像）对诊断至关重要。治疗基于疼痛控制和关节活动度的保留，包括低强度体育活动、非甾体类抗炎药和改善病情抗风湿药，治疗12个月后反应良好。无需手术。
