BACKGROUND: Hip disease is a major cause of immobility and pain in children and young adults with inflammatory arthritides. Total hip arthroplasty (THA) has previously been avoided in young patients because of the concern about durability of the prosthesis and the need for multiple revisions. There are now, however, growing reports of the success of such procedures in improving mobility and relieving pain in the young patient with severe hip disease. In this study we aimed to determine the clinical and radiological results in patients with inflammatory arthritides who had undergone THA before the age of 35 years. METHODS: Twenty-one patients who had undergone a total of 38 hip arthroplasties were identified. Patients' hips were scored both pre-operatively and at follow-up using the scoring system of the Hospital for Special Surgery, which allots a score for pain, walking, motion and muscle power, and function. Complications were noted and follow-up X-rays were compared to postoperative films to assess radiological loosening. RESULTS: The mean age at operation was 24 years, and the mean follow-up was 8.6 years. The results in terms of pain relief, mobility, movement and functional capacity were good. Revision was required in 13 hips (34%). This was mostly due to the failure of resurfacing prostheses. Radiological loosening was evident in a further six hips, five of which were asymptomatic. CONCLUSIONS: THA can dramatically improve the quality of life of the young patient with arthritis. The main concern is the likely need for multiple revisions, with progressive loss of bone stock.

Septic arthritis: a second decade of experience.

AIMS: To review the diagnostic features, treatment and outcomes of all cases of septic arthritis presenting to a major Australian rheumatology unit, between 1982 and 1991. These were compared with the previous decade's experience. METHODS: The medical records of all cases of septic arthritis presenting to the Combined Centre for Rheumatic Diseases, The Rachel Forster Hospital between 1982 and 1991 were reviewed and compared with the experience of the previous decade (1971-1981). RESULTS: Twenty-seven episodes of septic arthritis were diagnosed in 27 patients. There were 18 females and nine males. The average age was 62 (21-83) with three patients less than 30. Their rheumatological diagnoses were: rheumatoid arthritis (RA) in 15, osteoarthritis in five, gout in two, and one each of mixed connective disease, sarcoid, tenosynovitis of the forearm, seronegative spondyloarthropathy, and non specific polyarthritis. Eleven patients were on oral corticosteroids. Four patients had intra-articular injections within two months of the onset of the septic episode. Sixteen out of 19 aspirates on the wards were positive. The organisms identified were Staphylococcus aureus in ten (one multiply resistant S. aureus (MRSA), Streptococcus four, Mycobacterium three (one atypical), two Pseudomonas and one each of Citrobacter, Enterobacter, Gram negative bacillus. Five patients did not have a causative organism identified. The site of involvement and the causative organisms were similar in both decades. All patients received intravenous antibiotics for at least two weeks and oral antibiotics for at least another four weeks. Twenty-two per cent had regular aspirations on the wards and 26% had surgical drainage performed. Only 59% of all joints returned to good function. Fifty per cent of infected arthroplasties required arthrodesis and only a third of these returned to acceptable function. CONCLUSION: Septic arthritis in subjects with previous rheumatic disease continues to have a poor prognosis, especially in cases of infected arthroplasties. There has been no change in the types of causative organisms or sites of involvement over the last two decades.

Musculoskeletal disorders in the haemophilias.

The management of the haemophilias has been improved by the advent of potent consistent clotting factor replacement therapy. The previously lethal major complications such as intracerebral haemorrhage are now rare, and the infective complications of treatment, most notably hepatitis and AIDS, are now potentially preventable with the new synthetic products. There is also the prospect of 'cure' by gene insertion therapy. Advanced arthropathy has been minimized but not prevented by early effective treatment of haemarthroses, and there is a diminishing legacy of severely affected patients many of whom may require joint replacement surgery. The present group of such patients has a high prevalence of HIV-1 infection and an increased risk of joint sepsis. The available avenues of treatment for the subacute stage of the arthropathy have not been particularly effective, emphasizing the need to prevent recurrent bleeding. The development of a multidisciplinary team-management approach in centres of expertise has been a significant factor in the improved longevity, life satisfaction and preserved mobility now available to most haemophiliacs.

Autoantibodies to type II collagen: occurrence in rheumatoid arthritis, other arthritides, autoimmune connective tissue diseases, and chronic inflammatory syndromes.

Serum IgG antibodies to native and denatured human type II collagen (Col II) were measured using an enzyme linked immunosorbent assay (ELISA). One hundred and thirty one patients with various forms of arthritis such as rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PSA). Reiter's Syndrome (RS), osteoarthritis (OA), and gout, 60 with autoimmune connective tissue disease, and 37 with the chronic inflammatory conditions--graft versus host disease and leprosy--were studied. With the exception of RS, PSA, OA, and gout, significant levels of Col II antibodies were detected in each disease group. Blocking studies with types I and II collagen on selected serum samples confirmed the specificity to native Col II, though some cross reactivity was apparent with denatured collagen. The patients with RA who were Col II antibody positive tended to fall into stage III of disease progression. There was, however, no correlation with rheumatoid factor, erythrocyte sedimentation rate, or disease duration and this, together with the finding that Col II antibodies are present in a wide array of diseases, makes their role in the pathogenesis of RA questionable. They may arise as a secondary disease perpetuating mechanism in some patients, or in turn may be an epiphenomenon secondary to generalised disturbed immunoregulation or B cell hyperreactivity, or both, that characterises these clinical conditions.

Osteonecrosis after high dosage, short term corticosteroid therapy.

A retrospective review was made of 66 patients who had undergone neurosurgical treatment for intracranial aneurysms and who had been treated with high doses of corticosteroids to reduce postoperative cerebral edema. At a mean followup time of 50.3 months, one patient had developed bilateral osteonecrosis of the hips, among 44 who were available for followup.
