Femoral neck fractures are important causes of morbidity and mortality. Patients with end-stage renal diseases are 4,4-fold more likely to sustain a hip fracture that the general population. We present our own experience with treatment of femoral neck fractures in hemodialysis patients. The study included 12 patients (6 females and 6 males), mean age 51 years (range 41-77). They were dialysed for a mean duration of 125 months (range 12-271). The femoral neck fracture was treated by bipolar hip arthroplasty. The follow up was from 3 month to 6 years. We did not observe serious complications after operation. One patient was reoperated after 20 months, because of bipolar prosthesis protrusion. One patient died after 4 years from operation with normal hip function. The cause of death was decompensation of cirrhotic hepatitis. We estimate that severe secondary hyperparathyroidism is a risk factor of femoral neck fractures in hemodialysis patients.
