Aims. This study aimed to analyze the correlation between transverse
process (TP) fractures of the fourth (L4) and fifth (L5) lumbar
vertebrae and biomechanical and haemodynamic stability in patients
with a pelvic ring injury, since previous data are inconsistent. Patients and Methods. The study is a retrospective matched-pair analysis of patients
with a pelvic fracture according to the modified Tile AO Müller
and the Young and Burgess classification who presented to a level
1 trauma centre between January 2005 and December 2014. Results. A total of 728 patients with pelvic ring injuries were included,
of whom 183 (25.1%) had a biomechanically unstable pelvic fracture.
Of these patients, 84 (45.9%) had a fracture of a TP of L4 and/or
L5. A total of 73 patients (13.4%) with a stable pelvic ring injury
(p < 0.001) had a fracture of a TP. Patients with a fracture
of a TP of L4 and/or L5 had a 5.5-fold risk (odds ratio (OR)) of
having a biomechanically unstable pelvic injury. TP fractures (OR
1.6, p = 0.2) could not be confirmed as an independent predictor
of
Exsanguination is the second most common cause
of death in patients who suffer severe trauma. The management of
haemodynamically unstable high-energy pelvic injuries remains controversial,
as there are no universally accepted guidelines to direct surgeons
on the ideal use of pelvic packing or early angio-embolisation.
Additionally, the optimal resuscitation strategy, which prevents
or halts the progression of the trauma-induced coagulopathy, remains
unknown. Although early and aggressive use of blood products in
these patients appears to improve survival, over-enthusiastic resuscitative
measures may not be the safest strategy. This paper provides an overview of the classification of pelvic
injuries and the current evidence on best-practice management of
high-energy pelvic fractures, including resuscitation, transfusion
of blood components, monitoring of coagulopathy, and procedural
interventions including pre-peritoneal pelvic packing, external
fixation and angiographic embolisation. Cite this article:
We describe the impact of a targeted performance
improvement programme and the associated performance improvement
interventions, on mortality rates, error rates and process of care
for haemodynamically unstable patients with pelvic fractures. Clinical
care and performance improvement data for 185 adult patients with exsanguinating
pelvic trauma presenting to a United Kingdom Major Trauma Centre
between January 2007 and January 2011 were analysed with univariate
and multivariate regression and compared with National data. In
total 62 patients (34%) died from their injuries and opportunities
for improved care were identified in one third of deaths. Three major interventions were introduced during the study period
in response to the findings. These were a massive haemorrhage protocol,
a decision-making algorithm and employment of specialist pelvic
orthopaedic surgeons. Interventions which improved performance were
associated with an annual reduction in mortality (odds ratio 0.64
(95% confidence interval (CI) 0.44 to 0.93), p = 0.02), a reduction
in error rates (p = 0.024) and significant improvements in the targeted
processes of care. Exsanguinating patients with pelvic trauma are
complex to manage and are associated with high mortality rates;
implementation of a targeted performance improvement programme achieved
sustained improvements in mortality, error rates and trauma care
in this group of severely injured patients. Cite this article:
Crescent fracture dislocations are a well-recognised subset of pelvic ring injuries which result from a lateral compression force. They are characterised by disruption of the sacroiliac joint and extend proximally as a fracture of the posterior iliac wing. We describe a classification with three distinct types. Type I is characterised by a large crescent fragment and the dislocation comprises no more than one-third of the sacroiliac joint, which is typically inferior. Type II fractures are associated with an intermediate-size crescent fragment and the dislocation comprises between one- and two-thirds of the joint. Type III fractures are associated with a small crescent fragment where the dislocation comprises most, but not all of the joint. The principal goals of surgical intervention are the accurate and stable reduction of the sacroiliac joint. This classification proves useful in the selection of both the surgical approach and the reduction technique. A total of 16 patients were managed according to this classification and achieved good functional results approximately two years from the time of the index injury. Confounding factors compromise the summary short-form-36 and musculoskeletal functional assessment instrument scores, which is a well-recognised phenomenon when reporting the outcome of high-energy trauma.
We prospectively studied the outcome of a protocol of prophylaxis for deep vein thrombosis (DVT) in 103 consecutive patients undergoing surgical stabilisation of pelvic and acetabular fractures. Low-molecular-weight heparin (LMWH) was administered within 24 hours of injury or on achieving haemodynamic stability. Patients were screened for proximal DVT by duplex ultrasonography performed ten to 14 days after surgery. The incidence of proximal DVT was 10% and of pulmonary embolus 5%. Proximal DVT developed in two of 64 patients (3%) who had received LMWH within 24 hours of injury, but in eight of 36 patients (22%) who received LMWH more than 24 hours after the injury (p <
0.01). We conclude that LMWH, when begun without delay, is a safe and effective method of thromboprophylaxis in high-risk patients with major pelvic or acetabular fractures.
