A new complication of femur head core decompression surgery: compartment syndrome.

The basic surgical treatment for avascular necrosis of the femur head is core decompression. In this report we discuss a case where the patient developed compartment syndrome after core decompression surgery with history of anticoagulant use. A 49-year-old man, who was using Coumadin 5 mg once daily due to aortic valve replacement and atrial fibrillation, had undergone core decompression surgery done due to stage 2 femur head avascular necrosis (AVN).
