Avascular necrosis in five patients with human immunodeficiency virus (HIV) infection

Avascular necrosis (AVN) of bone occurring in patients infected with Human Immunodeficiency Virus (HIV) has been well documented in recent literature. Contributing factors may include drug treatment (steroids and protease inhibitors), hyperlipidaemia, hyperviscosity, antiphospholipid antibodies, or the virus itself. We have retrospectively reviewed case notes of all patients seen in our department with AVN (n=5). We conclude that although steroids play an important role, the aetiology of AVN in HIV is multifactoral. The orthopaedic surgeon should consider AVN in the differential diagnosis of patients with HIV infection presenting with painful joints.</jats:p

Total hip arthroplasties in young patients under 50 years: limited evidence for current trends. A descriptive literature review

Item does not contain fulltextWe examined all reported outcomes of uncemented and cemented total hip arthroplasty in patients younger than 50 years of age listed in Medline (1966- 1 January 2009) and PubMed, and scrutinised reference lists of relevant papers. In addition, we evaluated relevant data in the Swedish hip arthroplasty register. 109 relevant articles were identified, 37 of which had a mean follow-up longer than 10 years. Although uncemented implants are widely used in patients under 50 years of age, there are only 2 reports that fulfil the criteria published by the National Institute for Clinical Excellence (NICE) in the United Kingdom (follow-up of >10 yrs and survival of =90%). Current trends relating to implant selection remain unsupported by survival data, and additional information about the long-term results of newer implants is essential. As matters stand, the most reliable results relate to cemented implants
