title: Hip arthropathy associated with hemodialysis. Radiological and laboratory evaluation of 56 hemodialysis patients.
abstract: There were 56 consecutive patients enrolled in our study from the outpatient clinic of our institution, mean age of 59 years, who had been on hemodialysis for 2-26 years. The duration of hemodialysis was less than 10 years for 36 patients (short-term group) and 10 years or more for 20 patients (long-term group) with a mean duration of 11 years at time of the investigation. In the short-term group, plain radiography revealed bone cysts in 9 hips (17%) and joint space narrowing in 10 hips (19%), while in the long-term group, there were bone cysts in 19 hips (48%) and joint space narrowing in 6 hips (15%). Bone mineral density as determined by dual-energy X-ray absorptiometry was 0.621 g/cm2 for patients in the short-term group and 0.503 g/cm2 for patients in the long-term group. Hip arthroplasties were performed in 3 patients suffering from femoral neck fracture due to bone cysts. All of them showed marked bone loss (mean 0.380 g/cm2). In conclusion, plain radiography and dual-energy X-ray absorptiometry are useful for evaluating the hip arthropathy of hemodialysis patients, especially those who have undergone long-term hemodialysis.
