The aim of this study was to investigate the rate of revision for distal femoral arthroplasty (DFA) performed as a primary procedure for native knee fractures using data from the Australian Orthopaedic Association National Joint Arthroplasty Registry (AOANJRR). Data from the AOANJRR were obtained for DFA performed as primary procedures for native knee fractures from 1 September 1999 to 31 December 2020. Pathological fractures and revision for failed internal fixation were excluded. The five prostheses identified were the Global Modular Arthroplasty System, the Modular Arthroplasty System, the Modular Universal Tumour And Revision System, the Orthopaedic Salvage System, and the Segmental System. Patient demographic data (age, sex, and American Society of Anesthesiologists grade) were obtained, where available. Kaplan-Meier estimates of survival were used to determine the rate of revision, and the reasons for revision and mortality data were examined.Aims
Methods
Objectives. Bisphosphonates are widely used as first-line treatment for primary and secondary prevention of fragility fractures. Whilst they have proved effective in this role, there is growing concern over their long-term use, with much evidence linking bisphosphonate-related suppression of bone remodelling to an increased risk of atypical subtrochanteric fractures of the femur (AFFs). The objective of this article is to review this evidence, while presenting the current available strategies for the management of AFFs. Methods. We present an evaluation of current literature relating to the pathogenesis and treatment of AFFs in the context of bisphosphonate use. Results. Six broad themes relating to the pathogenesis and management of bisphosphonate-related AFFs are presented. The key themes in fracture pathogenesis are: bone microdamage accumulation; altered bone mineralisation and altered collagen formation. The key themes in fracture management are:
The aims of this study were to identify the early
in-hospital mortality rate after hip fracture, identify factors associated
with this mortality, and identify the cause of death in these patients.
A retrospective cohort study was performed on 4426 patients admitted
to our institution between the 1 January 2006 and 31 December 2013
with a hip fracture (1128 male (26%), mean age 82.0 years (60 to
105)). Admissions increased annually, but despite this 30-day mortality
decreased from 12.1% to 6.5%; 77% of these were in-hospital deaths.
Male gender (odds ratio (OR) 2.0, 95% confidence interval (CI) 1.3
to 3.0), increasing age (age ≥ 91; OR 4.1, 95% CI 1.4 to 12.2) and
comorbidity (American Society of Anesthesiologists grades 3 to 5;
OR 4.2, 95% CI 2.0 to 8.7) were independently and significantly
associated with increased odds of in-hospital mortality. From 220
post-mortem reports, the most common causes of death were respiratory
infections (35%), ischaemic heart disease (21%), and cardiac failure
(13%). A sub-group of hip fracture patients at highest risk of early
death can be identified with these risk factors, and the knowledge
of the causes of death can be used to inform service improvements
and the development of a more didactic care pathway, so that multidisciplinary
intervention can be focused for this sub-group in order to improve
their outcome. Cite this article:
