Femoral Neck Fracture in a Hemodialysis Patient after Liver Transplantation: A Case Report

BACKGROUND: Surgical treatment of femoral neck fractures is usually performed as an urgent procedure so that restoration of the ability to stand and walk can be achieved as quickly as possible. However, orthopedic surgeons need to be aware of undertreated or untreated diseases in their patients. Organ transplant recipients require immunosuppressive agents and steroids postoperatively. Hemodialysis patients also exhibit immunological deterioration and are included among immunocompromised patients. We report a case in which conservative treatment was chosen for a hepatic transplant recipient on hemodialysis who suffered a femoral neck fracture because signs of inflammation of unknown etiology were intermittently seen. CASE: The patient was a 70-year-old man who had undergone liver transplantation from a living donor as treatment for hepatocellular cancer and hepatic failure with cirrhosis. Dialysis for end-stage renal failure was initiated at approximately 1 year postoperatively. Cyclosporine was administered as an immunosuppressive agent. The patient subsequently fell off a bicycle and was unable to walk because of right hip pain. He was brought to our hospital by ambulance, and a right hip radiograph revealed a femoral neck fracture. His white blood cell count and C-reactive protein levels were intermittently elevated with unknown etiology. Conservative treatment was finally adopted, although a bipolar hip arthroplasty was planned. At 5 months after the injury, the patient was able to walk alone in a stable manner using a pair of crutches and was discharged. DISCUSSION: Conservative treatment for a femoral neck fracture, which generally requires surgery, may be acceptable in organ transplant recipients on hemodialysis.
