Total hip replacement in children with arthritis

Fourteen children with juvenile rheumatoid arthritis and two with ankylosing spondylitis received 29 total hip replacements (THR). The ages at THR were 12 to 18 years, the median duration of prior hip disease was 7.1 years, and the minimum followup was one year (range 1–4 years, median 2.2 years). The primary indication for THR was pain in 5 hips and severe malposition or flexion contractures in 24 hips. (Sixteen of these also had some degree of pain.) All 29 hips demonstrated improved postoperative range of motion, and all were free of pain. In children, active rheumatic disease in other joints, prosthesis longevity, and possible lack of adequate motivation all merit special consideration prior to THR, but the results are encouraging.     

Total hip replacement in patients aged 80 years and older

Total hip replacement was performed in 27 patients aged 80 years and older. In the early postoperative period, medical complications occurred in 13 patients and arthroplasty-related complications in 5 patients. At the time of the follow-up, after an average of 31 months, there was one case of acetabular cup loosening, which was revised. Twenty of 22 patients were free from pain at rest, and the social function of the patients had remained almost unchanged.     

Total joint replacement

As of 1980, approximately 1,800,000 people reached the age of 65 each year in the United States. It may be estimated that each year 35,000 of these people would benefit from total hip replacement surgery and are medically fit for it. Numbers for knee replacement are similar. Other joint replacements are much less in number but may be equally done when indicated. With the constant improvement of surgical technique, prostheses, and medical expertise, these people can be offered significant improvement in the quality of life by replacement of painful disabling joints.     

Total joint replacement in osteoarthritis

Surgical approaches have been developed for most of the sites of osteoarthritis, including the carpal metacarpal and first metatarsal phalangeal joint, the hips, knees, shoulders, ankles and elbows. This chapter will address surgical options for advanced osteoarthritis of the hips and knees and will focus primarily on total hip and knee replacement.     

Total knee replacement in haemophilia

We believe that total knee replacement (TKR) is a safe and effective procedure for the management of haemophiliac joint arthropathy; however, the increased risk of infection and non-infective complications remain a cause for concern. TKR in haemophilic patients carries with it an increased risk of post-operative infection in comparison to non-haemophiliac patients. Those patients at particular risk are the HIV-positive haemophiliac patients whose CD4 count is less than 200 cells mm-3. The latest techniques have gone a long way to reducing the complication rate and to achieving results that match those of a similar non-haemophiliac population.     

International variation in hip replacement rates

OBJECTIVES: To summarise epidemiological data on the frequency of hip replacements in the countries of the developed world, especially in countries of the Organisation for Economic Cooperation and Development (OECD), and to investigate whether missing consensus criteria for the indication for total hip replacement (THR) result in different replacement rates. METHODS: Country-specific hip replacement rates were collected using the available literature, different data sources of national authorities, and estimates of leading hip replacement manufacturers. RESULTS: According to administrative and literature data sources the reported crude primary THR rate varied between 50 and 130 procedures/100000 inhabitants in OECD countries in the 1990s. The crude overall hip implantation rate, summarising THR, partial hip replacement, and hip revision procedures, was reported to range from 60 to 200 procedures/100000 inhabitants in the late 1990s. Moreover, large national differences were seen in the relationship between total and partial hip replacement procedures. CONCLUSION: The reported differences in hip replacement rates in OECD countries are substantial. They may be due to various causes, including different coding systems, country-specific differences in the healthcare system, in total expenditure on health per capita, in the population age structure, and in different indication criteria for THR.     

Total joint replacement in childhood arthritis

Juvenile rheumatoid arthritis poses a distinct challenge to pediatric rheumatologists and orthopedic surgeons. Recent developments in the medical management of juvenile rheumatoid arthritis have decreased the need for surgical intervention in this subset of patients; however, those patients who need surgery are often the most challenging cases due to their relatively small bone size, the complex deformity caused by soft tissue contractures, and the tendency for multiple joint involvement. Nonetheless, technologic improvements in implant design and surgical techniques have led to successful outcomes in otherwise debilitating conditions. A careful and coordinated approach to the surgical management of juvenile rheumatoid arthritis can lead to improved function and significant pain relief for children with rheumatoid arthritis.

Early morbidity after total hip replacement

The authors used the California Health Facilities Discharge data for 1984 and 1985 to compare retrospectively in-hospital morbidity and mortality of all 721 patients with rheumatoid arthritis versus all 8,859 patients with osteoarthritis who underwent a non-emergent, first-time, unilateral total hip arthroplasty. The lengths of hospitalization, in-hospital mortality rates, and incidences of postoperative complications were similar in the two groups except for higher rates of wound infection and wound dehiscence in the patients with rheumatoid arthritis and a higher rate of thromboembolic events in the osteoarthritis group. The short-term outcome of patients with rheumatoid arthritis appears comparable to that of patients with osteoarthritis.
