It seems that bleeding from the holes of proximal cannulated screws is a simple and accurate perfusion assessment technique for predicting the development of AVNFH after a femoral neck fracture. Given that assumption, primary arthroplasty might be an appropriate choice as a treatment method in a nonbleeding-group patient whose treatment choice is ambivalent or who might not be able to undergo additional surgery should he or she develop a subsequent AVNFH after internal fixation of femoral neck fracture.

Kienböck's disease, which consists of osteonecrosis and collapse of the lunate bone, causes chronic pain and dysfunction of the wrist. Patients on hemodialysis are occasionally present with wrist pain, but Kienböck's disease is rarely reported in dialysis patients. This case study describes Kienböck's disease in a patient with end-stage renal disease on hemodialysis. A 39-year-old male with a 1-year history of hemodialysis presented with left wrist pain that increased progressively over 6 months. The patient had no history of trauma or any other risk factors known to be associated with Kienböck's disease. Physical examination of the wrist at the site of the arteriovenous fistula showed swelling and tenderness with decreased range of motion. Radiographic examination showed articular collapse and fracture of the body of lunate consistent with stage IIIb Kienböck's disease. An intercarpal arthrodesis with autogenous bone graft was performed.
