Osteonecrosis of the femoral head due to brucellosis: a case
Osteonecrosis of the femoral head (ONFH) is a devastating disease that affects patients’ life with pain, dysfunction of walking and always lead to total hip arthroplasty (THA). Researchers presented a case with osteonecrosis of the femoral head that was very likely due to the infection of Brucella spp.

The patient was a 49 years-old male who was a herder living in Inner Mongolia, the northern part of China. He first showed recurrent fever then presented bilateral hip pain, which was confirmed to be brucellosis and ONFH on the right side of the hip. He was admitted to the hospital & showed bilateral ONFH with the restrictive movement of both hips. Doctors performed THA after it was confirmed that the infection has been cured. The patient can walk with the help of the walker the second day after surgery.

The patient showed limited active and passive hip movement, the abduction and adduction were significantly restricted, Patrick test and Thomas sign were both positive on both sides, Harris Hip Score were 54 on the right side and 45 on the left side.

Brucellosis is still a common epidemic disease worldwide, which can lead to many complications, brucellosis arthritis is the most common complication of Brucellosis. Osteonecrosis of the femoral head can also present in the patients with brucellosis. All the patients presented with recurrent fever and hip pain, who is from the epidemic region, should be taken both septic arthritis and ONFH into consideration.
