[Idiopathic chondrolysis of the hip-joint: report of two cases and review of the literature].
Two cases of idiopathic chondrolysis of the hip-joint in chinese boys were treated by the authors. By consulting medical literature, the etiology, diagnosis and treatment of this disease were discussed in this paper. The real cause of this disease is still unknown. When a preschool child, especially a girl, complains of pain and limitation of movement at one hip-joint without evident predisposing cause, plus narrowing of inter-articular space revealed by roentgenogram and normal values in hematology and ESR, this disease should be ruled out. Owing to lack of ideal therapy up to now, pain can be alleviated and ankylosis be prevented by performing active and passive functional exercises of the joint persistently under light load or no load conditions. Besides, immobilization of the joint by brace and plaster bandage are contraindications for this disease.
