Total hip replacement causes a short-term increase
in the risk of mortality. It is important to quantify this and to identify
modifiable risk factors so that the risk of post-operative mortality
can be minimised. We performed a systematic review and critical
evaluation of the current literature on the topic. We identified
32 studies published over the last 10 years which provide either
30-day or 90-day mortality data. We estimate the pooled incidence
of mortality during the first 30 and 90 days following hip replacement
to be 0.30% (95% CI 0.22 to 0.38) and 0.65% (95% CI 0.50 to 0.81),
respectively. We found strong evidence of a temporal trend towards
reducing mortality rates despite increasingly co-morbid patients.
The risk factors for early mortality most commonly identified are
increasing age, male gender and co-morbid conditions, particularly
cardiovascular disease. Cardiovascular complications appear to have
overtaken fatal pulmonary emboli as the leading cause of death after
hip replacement. Cite this article:
Hip arthrodesis remains a viable surgical technique
in well selected patients, typically the young manual labourer with
isolated unilateral hip disease. Despite this, its popularity with
patients and surgeons has decreased due to the evolution of hip
replacement, and is seldom chosen by young adult patients today.
The surgeon is more likely to encounter a patient who requests conversion
to total hip replacement (THR). The most common indications are
a painful pseudarthrosis, back pain, ipsilateral knee pain or contralateral
hip pain. Occasionally the patient will request conversion because
of difficulty with activities of daily living, body image and perceived
cosmesis. The technique of conversion and a discussion of the results
are presented. Cite this article:
