Abstract
A case of spontaneous fractures of the bilateral femoral neck in a patient with rheumatoid arthritis is reported. A 67 year old female visited our hospital with a chief complaint of the right coxalgia, and because of gait disturbance, was hospitalized. In a roentgenogram, a bone fracture overlooked in the first test was observed in the second diagnosis as a fracture of Garden type III. An artificial head replacement was performed, but left coxalgia, similar to the right coxalgia, developed thereafter. Since a Garden type III fracture was observed in the second rentgenogram, an artificial head replacement was performed in the left side also. As is often the case, the diagnosis of spontaneous fracture was difficult. However, since early treatment is important when a patient with a heavy bone atrophy complains of pain, treatment should be performed with this disease in mind, even if the roentgenogram shows no apparent change.
