Venous thromboembolism (VTE) remains an immediate
threat to patients following total hip and knee replacement. While
there is a strong consensus that steps should be taken to minimise
the risk to patients by utilising some forms of prophylaxis for
the vast majority of patients, the methods utilised have been extremely
variable. Clinical practice guidelines (CPGs) have been published
by various professional organisations for over 25 years to provide recommendations
to standardise VTE prophylaxis. Historically, these recommendations
have varied widely depending in underlying assumptions, goals, and
methodology of the various groups. This effort has previously been
exemplified by the American College of Chest Physicians (ACCP) and
the American Academy of Orthopaedic Surgeons (AAOS). The former
group of medical specialists targeted minimising venographically
proven deep vein thrombosis (DVT) (the vast majority of which are
asymptomatic) as their primary goal prior to 2012. The latter group of
surgeons targeted minimising symptomatic VTE. As a result prior
to 2012, the recommendations of the two groups were widely divergent.
In the past year, both groups have reassessed the current literature
with the principal goals of minimising symptomatic VTE events and
bleeding complications. As a result, for the first time the CPGs
of these two major subspecialty organisations are in close agreement.
High energy fractures of the pelvis are a challenging problem both in the immediate post-injury phase and later when definitive fixation is undertaken. No single management algorithm can be applied because of associated injuries and the wide variety of trauma systems that have evolved around the world. Initial management is aimed at saving life and this is most likely to be achieved with an approach that seeks to identify and treat life-threatening injuries in order of priority. Early mortality after a pelvic fracture is most commonly due to major haemorrhage or catastrophic brain injury. In this article we review the role of pelvic binders, angiographic embolisation, pelvic packing, early internal fixation and blood transfusion with regard to controlling haemorrhage. Definitive fixation seeks to prevent deformity and reduce complications. We believe this should be undertaken by specialist surgeons in a hospital resourced, equipped and staffed to manage the whole spectrum of major trauma. We describe the most common modes of internal fixation by injury type and review the factors that influence delayed mortality, adverse functional outcome, sexual dysfunction and venous thromboembolism.
Thromboprophylaxis remains a controversial subject. A vast amount of epidemiological and trial data about venous thromboembolism has been published over the past 40 years. These data have been distilled and synthesised into guidelines designed to help the practitioner translate this extensive research into ‘evidence-based’ advice. Guidelines should, in theory, benefit patient care by ensuring that every patient routinely receives the best prophylaxis; without guidelines, it is argued, patients may fail to receive treatment or be exposed to protocols which are ineffective, dangerous or expensive. Guidelines, however, have not been welcomed or applied universally. In the United States, orthopaedic surgeons have published their concerns about the
