Total hip arthroplasty in hemodialysis and renal transplant patients

Abstract

Osteoarticular complications are common in patients with chronic renal failure and they often require implantation of a hip arthroplasty (total or partial) due to osteoarthritis, femoral neck fracture or ischemic necrosis of multifactor aetiology. Between 1992 and 2005 we operated on eighteen patients (23 hips) with chronic renal failure who were receiving renal replacement therapy (ten haemodialysis and eight renal transplants), and in each case either a total or partial hip arthroplasty was implanted. This group comprised nine women and nine men, with a mean age of 56 years (range: 30–83). Five cases were bilateral. The clinical diagnoses were necrosis (fourteen cases), femoral neck fracture (five cases) and osteoarthritis (three cases). The main early complications were haemorrhage in seventeen cases (74%) and infection in six cases (33%) (two urinary infections and four of the surgical wound). The late complications involved eight cases (35%) of prosthetic loosening (five aseptic and three septic). The surgery-related mortality rate was 17% (three cases). Prosthetic hip surgery in patients receiving renal replacement therapy is associated with high morbidity and mortality, thus highlighting the importance of careful patient selection.
