There have been many advances in the resuscitation
and early management of patients with severe injuries during the
last decade. These have come about as a result of the reorganisation
of civilian trauma services in countries such as Germany, Australia
and the United States, where the development of trauma systems has
allowed a concentration of expertise and research. The continuing
conflicts in the Middle East have also generated a significant increase
in expertise in the management of severe injuries, and soldiers
now survive injuries that would have been fatal in previous wars.
This military experience is being translated into civilian practice. The aim of this paper is to give orthopaedic surgeons a practical,
evidence-based guide to the current management of patients with
severe, multiple injuries. It must be emphasised that this depends
upon the expertise, experience and facilities available within the
local health-care system, and that the proposed guidelines will
inevitably have to be adapted to suit the local resources.
Whether to use total or unicompartmental knee
replacement (TKA/UKA) for end-stage knee osteoarthritis remains controversial.
Although UKA results in a faster recovery, lower rates of morbidity
and mortality and fewer complications, the long-term revision rate
is substantially higher than that for TKA. The effect of each intervention on
patient-reported outcome remains unclear. The aim of this study
was to determine whether six-month patient-reported outcome measures
(PROMs) are better in patients after TKA or UKA, using data from
a large national joint registry (NJR). We carried out a propensity score-matched cohort study which
compared six-month PROMs after TKA and UKA in patients enrolled
in the NJR for England and Wales, and the English national PROM
collection programme. A total of 3519 UKA patients were matched
to 10 557 TKAs. The mean six-month PROMs favoured UKA: the Oxford Knee Score
was 37.7 (95% confidence interval (CI) 37.4 to 38.0) for UKA and
36.1 (95% CI 35.9 to 36.3) for TKA; the mean EuroQol EQ-5D index
was 0.772 (95% CI 0.764 to 0.780) for UKA and 0.751 (95% CI 0.747
to 0.756) for TKA. UKA patients were more likely to achieve excellent
results (odds ratio (OR) 1.59, 95% CI 1.47 to 1.72, p <
0.001)
and to be highly satisfied (OR 1.27, 95% CI 1.17 to 1.39, p <
0.001), and
were less likely to report complications than those who had undergone
TKA. UKA gives better early patient-reported outcomes than TKA; these
differences are most marked for the very best outcomes. Complications
and readmission are more likely after TKA. Although the data presented
reflect the short-term outcome, they suggest that the high revision
rate for UKA may not be because of poorer clinical outcomes. These
factors should inform decision-making in patients eligible for either
procedure. Cite this article:

Compartment pressures have not previously been studied in healthy children. We compared the pressures in the four lower leg compartments of healthy children with those of healthy adults. We included patients aged between two months and six years, and measured the pressures in 80 compartments of 20 healthy children using simple needle manometry. Measurements were repeated in a control group of 20 healthy adults. The mean compartment pressure in the lower leg in children was significantly higher than in adults (p <
0.001). On average, pressures in the four compartments varied between 13.3 mmHg and 16.6 mmHg in the children and between 5.2 mmHg and 9.7 mmHg in the adults. The latter is in accordance with those recorded in the literature. The mean arterial pressure did not relate to age or to pressure in the compartment. The findings of this study that the normal compartment pressure of the lower leg in healthy children is significantly higher than that in adults may be of considerable significance in clinical decision-making in children of this age.
Metal-on-metal (MoM) hip resurfacing was introduced into clinical
practice because it was perceived to be a better alternative to
conventional total hip replacement for young and active patients.
However, an increasing number of reports of complications have arisen
focusing on design and orientation of the components, the generation
of metallic wear particles and serum levels of metallic ions. The
procedure introduced a combination of two elements: large-dimension
components and hard abrasive particles of metal wear. The objective
of our study was to investigate the theory that microseparation
of the articular surfaces draws in a high volume of bursal fluid
and its contents into the articulation, and at relocation under
load would generate high pressures of fluid ejection, resulting
in an abrasive water jet. This theoretical concept using MoM resurfacing components (head
diameter 55 mm) was modelled mathematically and confirmed experimentally
using a material-testing machine that pushed the head into the cup
at a rate of 1000 mm/min until fully engaged.Objectives

The Mangled Extremity Severity Score (MESS) may be used to decide whether to perform amputation in patients with injuries involving a limb. A score of 7 points or higher indicates the need for amputation. We have treated three patients with a MESS of 7 points or higher, in two of which the injured limb was salvaged. This scoring system was originally devised to assess injuries to the lower limb. However, a MESS of 7 points as a justification for amputation does not appear appropriate when assessing injuries to the major vessels in the upper limb.
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:
We report the incidence of and risk factors for
complications after scoliosis surgery in patients with Duchenne muscular
dystrophy (DMD) and compare them with those of other neuromuscular
conditions. We identified 110 (64 males, 46 females) consecutive patients
with a neuromuscular disorder who underwent correction of the scoliosis
at a mean age of 14 years (7 to 19) and had a minimum two-year follow-up.
We recorded demographic and peri-operative data, including complications
and re-operations. There were 60 patients with cerebral palsy (54.5%) and 26 with
DMD (23.6%). The overall complication rate was 22% (24 patients),
the most common of which were deep wound infection (9, 8.1%), gastrointestinal
complications (5, 4.5%) and hepatotoxicity (4, 3.6%). The complication
rate was higher in patients with DMD (10/26, 38.5%) than in those
with other neuromuscular conditions (14/84, 16.7% (p = 0.019). All
hepatotoxicity occurred in patients with DMD (p = 0.003), who also
had an increased rate of deep wound infection (19% In our series, correction of a neuromuscular scoliosis had an
acceptable rate of complications: patients with DMD had an increased
overall rate compared with those with other neuromuscular conditions.
These included deep wound infection and hepatotoxicity. Hepatotoxicity
was unique to DMD patients, and we recommend peri-operative vigilance
after correction of a scoliosis in this group. Cite this article:
This paper summarises the current knowledge on the effects of medullary reaming of long-bone fractures. Following a review of intramedullary vascular physiology, the consequences for vascularity, the autograft effects, the generation of heat, and fat embolism are outlined. Also, alternative reaming techniques are described.
Over a two-year period, 265 Norwegian orthopaedic surgeons working at 71 institutions performed 63 484 operations under a tourniquet. Their replies to a questionnaire revealed that they mostly followed modern guidelines in their use of the tourniquet. Most felt that the tourniquet could be left on for two hours, and that it could be re-applied after 15 minutes. A total of 26 complications (one in 2442 operations) that might have been due to the tourniquet were reported, of which 15 were neurological. Three were in the upper limb (one in 6155 operations) and 12 in the lower limb (one in 3752 operations). Two were permanent (one in 31742 operations), but the remainder resolved within six months. One permanent and one transient complication occurred after tourniquet times of three hours. The incidence of tourniquet complications is still at least as high as that estimated in the 1970s.
We describe a case of bilateral weakness of the lower limbs, sensory disturbance and intermittent urinary incontinence, secondary to untreated Gitelman’s syndrome, in a 42-year-old female who was referred with presumed cauda equina syndrome. On examination, the power of both legs was uniformly reduced, and the perianal and lower-limb sensation was altered. However, MRI of the lumbar spine was normal. Measurements of serum and urinary potassium were low and blood gas analysis revealed metabolic alkalosis. Her symptoms resolved following potassium replacement. We emphasise the importance of measurement of the plasma and urinary levels of electrolytes in the investigation of patients with paralysis of the lower limbs and suggest that they, together with blood gas analysis, allow the exclusion of unusual causes of muscle weakness resulting from metabolic disorders such as metabolic alkalosis.
We performed a meta-analysis to evaluate the relative efficacy of regional and general anaesthesia in patients undergoing total hip or knee replacement. A comprehensive search for relevant studies was performed in PubMed (1966 to April 2008), EMBASE (1969 to April 2008) and the Cochrane Library. Only randomised studies comparing regional and general anaesthesia for total hip or knee replacement were included. We identified 21 independent, randomised clinical trials. A random-effects model was used to calculate all effect sizes. Pooled results from these trials showed that regional anaesthesia reduces the operating time (odds ratio (OR) −0.19; 95% confidence interval (CI) −0.33 to −0.05), the need for transfusion (OR 0.45; 95% CI 0.22 to 0.94) and the incidence of thromboembolic disease (deep-vein thrombosis OR 0.45, 95% CI 0.24 to 0.84; pulmonary embolism OR 0.46, 95% CI 0.29 to 0.80). Regional anaesthesia therefore seems to improve the outcome of patients undergoing total hip or knee replacement.
We carried out an audit on the result of achieving early walking in total knee replacement after instituting a new rehabilitation protocol, and assessed its influence on the development of deep-vein thrombosis as determined by Doppler ultrasound scanning on the fifth post-operative day. Early mobilisation was defined as beginning to walk less than 24 hours after knee replacement. Between April 1997 and July 2002, 98 patients underwent a total of 125 total knee replacements. They began walking on the second post-operative day unless there was a medical contraindication. They formed a retrospective control group. A protocol which allowed patients to start walking at less than 24 hours after surgery was instituted in August 2002. Between August 2002 and November 2004, 97 patients underwent a total of 122 total knee replacements. They formed the early mobilisation group, in which data were prospectively gathered. The two groups were of similar age, gender and had similar medical comorbidities. The surgical technique and tourniquet times were similar and the same instrumentation was used in nearly all cases. All the patients received low-molecular-weight heparin thromboprophylaxis and wore compression stockings post-operatively. In the early mobilisation group 90 patients (92.8%) began walking successfully within 24 hours of their operation. The incidence of deep-vein thrombosis fell from 27.6% in the control group to 1.0% in the early mobilisation group (chi-squared test, p <
0.001). There was a difference in the incidence of risk factors for deep-vein thrombosis between the two groups. However, multiple logistic regression analysis showed that the institution of an early mobilisation protocol resulted in a 30-fold reduction in the risk of post-operative deep-vein thrombosis when we adjusted for other risk factors.
A total of 187 patients with primary osteoarthritis
(OA) of the knee undergoing total knee replacement (TKR) were randomly
divided into two groups, one of which underwent synovectomy. The
patients and assessors were blinded to the randomisation both before
and after surgery. The duration of surgery, hospitalisation period,
concealed bleeding, drainage volume, blood transfusion rate and
range of movement of the knee at three days after the operation
were analysed. Patients were followed up at four weeks and 12 months
after their operation, and a visual analogue score (VAS) for pain,
Knee Society score (KSS) and a patellar ballottement test were compared
between the groups. The mean amount of concealed bleeding was higher in the synovectomy
group compared with the control group (1.24 l (0.08 to 3.28) Cite this article:
Despite the increasing prevalence of sleep apnoea,
little information is available regarding its impact on the peri-operative
outcome of patients undergoing posterior lumbar fusion. Using a
national database, patients who underwent lumbar fusion between
2006 and 2010 were identified, sub-grouped by diagnosis of sleep
apnoea and compared. The impact of sleep apnoea on various outcome
measures was assessed by regression analysis. The records of 84
655 patients undergoing posterior lumbar fusion were identified
and 7.28% (n = 6163) also had a diagnostic code for sleep apnoea.
Compared with patients without sleep apnoea, these patients were
older, more frequently female, had a higher comorbidity burden and
higher rates of peri-operative complications, post-operative mechanical
ventilation, blood product transfusion and intensive care. Patients
with sleep apnoea also had longer and more costly periods of hospitalisation. In the regression analysis, sleep apnoea emerged as an independent
risk factor for the development of peri-operative complications
(odds ratio (OR) 1.50, confidence interval (CI) 1.38;1.62), blood
product transfusions (OR 1.12, CI 1.03;1.23), mechanical ventilation
(OR 6.97, CI 5.90;8.23), critical care services (OR 1.86, CI 1.71;2.03), prolonged
hospitalisation and increased cost (OR 1.28, CI 1.19;1.37; OR 1.10,
CI 1.03;1.18). Patients with sleep apnoea who undergo posterior lumbar fusion
pose significant challenges to clinicians. Cite this article:
Rupture of an aneurysm of the common iliac artery is a rare cause of pain in the hip. We describe an elderly hypertensive patient with an aneurysmal rupture of the left common iliac artery who presented with unilateral hip pain masquerading as septic arthritis.
Limited forefoot amputation in diabetic patients
with osteomyelitis is frequently required. We retrospectively reviewed
diabetic patients with osteomyelitis, an unhealed ulcer and blood
pressure in the toe of >
45 mmHg who underwent limited amputation
of the foot with primary wound closure. Between 2006 and 2012, 74
consecutive patients with a mean age of 67 years (29 to 93), and
a median follow-up of 31 months, were included. All the wounds healed
primarily at a median of 37 days (13 to 210; mean 48). At a median
of 6 months (1.5 to 18; mean 353 days), 23 patients (31%) suffered
a further ulceration. Of these, 12 patients (16% of the total) required
a further amputation. We conclude that primary wound closure following limited amputation
of the foot in patients with diabetes is a safe and effective technique
when associated with appropriate antibiotic treatment. Cite this article:
We aimed to examine the characteristics of deep venous flow in
the leg in a cast and the effects of a wearable neuromuscular stimulator
(geko; FirstKind Ltd) and also to explore the participants’ tolerance
of the stimulator. This is an open-label physiological study on ten healthy volunteers.
Duplex ultrasonography of the superficial femoral vein measured
normal flow and cross-sectional area in the standing and supine
positions (with the lower limb initially horizontal and then elevated).
Flow measurements were repeated during activation of the geko stimulator
placed over the peroneal nerve. The process was repeated after the
application of a below-knee cast. Participants evaluated discomfort
using a questionnaire (verbal rating score) and a scoring index
(visual analogue scale).Objectives
