Idiopathic chondrolysis of the hip (ICH) is a rare condition with only a few cases reported in the literature. The average age at the onset of the disease is 11 years, with females having six times higher incidence than males. We report two cases of ICH in two medically free 10-year-old females who presented with atraumatic insidious hip pain and limping. No significant past medical, surgical, or family history was recorded. Laboratory studies were within normal limits, and the imaging showed the pathogenic changes of hip chondrolysis. Both cases were treated conservatively, and regular follow-ups in the clinic showed progressive limitation of the hip range of motion with arthritic changes on plain radiographs. Altogether, ICH is rare and can be misdiagnosed as inflammatory or infectious hip arthritis. Clinical assessment and image interpretation can lead to early diagnosis. Pain management and physical therapy with a prolonged period of protected weight-bearing are the mainstays of treatment.
髋关节特发性软骨溶解症（ICH）是一种罕见病，文献中仅有少数病例报道。该病发病的平均年龄为11岁，女性发病率比男性高6倍。我们报告两例ICH病例，患者为两名10岁无基础疾病的女性，均有无创伤性隐匿性髋关节疼痛和跛行症状。既往无重大疾病史、手术史或家族史。实验室检查结果均在正常范围内，影像学检查显示髋关节软骨溶解的病变情况。两例患者均接受保守治疗，门诊定期随访显示髋关节活动范围逐渐受限，X线平片出现关节炎改变。总之，ICH较为罕见，可能被误诊为炎症性或感染性髋关节炎。临床评估和影像解读有助于早期诊断。疼痛管理以及长时间保护性负重的物理治疗是主要治疗方法。
