The April 2012 Trauma Roundup360 looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries
The aim of this study was to determine whether the foundation programme for junior doctors, implemented across the United Kingdom in 2005, provides adequate training in musculoskeletal medicine. We recruited 112 doctors on completion of their foundation programme and assessed them using the Freedman and Bernstein musculoskeletal examination tool. Only 8.9% passed the assessment. Those with exposure to orthopaedics, with a career interest in orthopaedics, and who felt that they had gained adequate exposure to musculoskeletal medicine obtained significantly higher scores. Those interested in general practice as a career obtained significantly lower scores. Only 15% had any exposure to orthopaedics during the foundation programme and only 13% felt they had adequate exposure to musculoskeletal medicine. The foundation programme currently provides inadequate training in musculoskeletal medicine. The quality and quantity of exposure to musculoskeletal medicine during the foundation programme must be improved.
The June 2012 Spine Roundup360 looks at: back pain; spinal fusion for tuberculosis; anatomical course of the recurrent laryngeal nerve; groin pain with normal imaging; the herniated intervertebral disc; obesity’s effect on the spine; the medicolegal risks of cauda equina syndrome; and intravenous lidocaine use and failed back surgery syndrome.
In a prospective multicentre study we investigated
variations in pain management used by knee arthroplasty surgeons
in order to compare the differences in pain levels among patients
undergoing total knee replacements (TKR), and to compare the effectiveness
of pain management protocols. The protocols, peri-operative levels
of pain and patient satisfaction were investigated in 424 patients
who underwent TKR in 14 hospitals. The protocols were highly variable
and peri-operative pain levels varied substantially, particularly
during the first two post-operative days. Differences in levels
of pain were greatest during the night after TKR, when visual analogue
scores ranged from 16.9 to 94.3 points. Of the methods of managing pain, the combined use of peri-articular
infiltration and nerve blocks provided better pain relief than other
methods during the first two post-operative days. Patients managed
with peri-articular injection plus nerve block, and epidural analgesia
were more likely to have higher satisfaction at two weeks after TKR.
This study highlights the need to establish a consistent pain management
strategy after TKR.

Procedures performed at the incorrect anatomical site are commonly perceived as being relatively rare. However, they can be a devastating event for patients and doctors. Evidence from the United Kingdom and North America suggests that wrong-site, wrong-procedure and wrong-patient events occur more commonly than we think. Furthermore, their incidence may be increasing as NHS Trusts increase the volume and complexity of procedures undertaken in order to cope with increasing demands on the system. In previous studies from North America orthopaedic surgery has been found to be the worst-offending specialty. In this paper we review the existing literature on wrong-site surgery and analyse data from the National Patient Safety Agency and NHS Litigation Authority on 292 cases of wrong-site surgery in England and Wales. Orthopaedic surgery accounted for 87 (29.8%) of these cases. In the year 2006 to 2007, the rate of wrong-site surgery in England and Wales was highest in orthopaedic surgery, in which the estimated rate was 1:105 712 cases.
Using general practitioner records and hospital
notes and through direct telephone conversation with patients, we investigated
the accuracy of nine patient-reported complications gathered from
a self-completed questionnaire after elective joint replacement
surgery of the hip and knee. A total of 402 post-discharge complications
were reported after 8546 elective operations that were undertaken
within a three-year period. These were reported by 136 men and 240
women with a mean age of 71.8 years (34 to 93). A total of 319 reported
complications (79.4%; 95% confidence interval 75.4 to 83.3) were
confirmed to be correct. High rates of correct reporting were demonstrated
for infection (94.5%) and the need for further surgery (100%), whereas
the rates of reporting deep-vein thrombosis (DVT), pulmonary embolism,
myocardial infarction and stroke were lower (75% to 84.2%). Dislocation,
peri-prosthetic fractures and nerve palsy had modest rates of correct
reporting (36% to 57.1%). More patients who had knee surgery delivered
incorrect reports of dislocation (p = 0.001) and DVT (p = 0.013). Despite these variations, it appears that post-operative complications
may form part of a larger patient-reported outcome programme after
elective joint replacement surgery.
The benefit of arthroscopy of the hip in the
treatment of femoroacetabular impingement (FAI) in terms of quality
of life (QoL) has not been reported. We prospectively collected
data on 612 patients (257 women (42%) and 355 men (58%)) with a
mean age at the time of surgery of 36.7 years (14 to 75) who underwent
arthroscopy of the hip for FAI under the care of a single surgeon.
The minimum follow-up was one year (mean 3.2 years (1 to 7)). The
responses to the modified Harris hip score were translated using
the Rosser Index Matrix in order to provide a QoL score. The mean
QoL score increased from 0.946 (-1.486 to 0.995) to 0.974 (0.7 to
1) at one year after surgery (p <
0.001). The mean QoL score
in men was significantly higher than in women, both before and one
year after surgery (both p <
0.001). However, the mean change
in the QoL score was not statistically different between men and
women (0.02 (-0.21 to 0.27) and 0.04 (-0.16 to 0.87), respectively;
p = 0.12). Linear regression analysis revealed that the significant predictors
of a change in QoL score were pre-operative QoL score (p <
0.001)
and gender (p = 0.04). The lower the pre-operative score, the higher
the gain in QoL post-operatively (ρ = -0.66; p <
0.001). One
year after surgery the QoL scores in the 612 patients had improved
in 469 (76.6%), remained unchanged in 88 (14.4%) and had deteriorated
in 55 (9.0%).
Osteoarthritis (OA) is an important cause of
pain, disability and economic loss in humans, and is similarly important in
the horse. Recent knowledge on post-traumatic OA has suggested opportunities
for early intervention, but it is difficult to identify the appropriate
time of these interventions. The horse provides two useful mechanisms
to answer these questions: 1) extensive experience with clinical
OA in horses; and 2) use of a consistently predictable model of
OA that can help study early pathobiological events, define targets
for therapeutic intervention and then test these putative therapies.
This paper summarises the syndromes of clinical OA in horses including
pathogenesis, diagnosis and treatment, and details controlled studies
of various treatment options using an equine model of clinical OA.
Multicentre clinical trials in trauma care are gaining prominence as a means of generating good-quality evidence to inform and influence clinical practice. We believe multicentre trials have an important role to play in supporting evidence-based practice, and further investment in such trials is justified.
This year is the centenary of the birth of John Charnley. Some of his legacy to Orthopaedic Surgery is described in this editorial.
The ideal bearing surface for young patients
undergoing total hip replacement (THR) remains controversial. We report
the five-year results of a randomised controlled trial comparing
the clinical and radiological outcomes of 102 THRs in 91 patients
who were <
65 years of age. These patients were randomised to
receive a cobalt–chrome on ultra-high-molecular-weight polyethylene,
cobalt–chrome on highly cross-linked polyethylene, or a ceramic-on-ceramic
bearing. In all, 97 hip replacements in 87 patients were available
for review at five years. Two hips had been revised, one for infection
and one for peri-prosthetic fracture. At the final follow-up there were no significant differences
between the groups for the mean Western Ontario and McMaster Universities
osteoarthritis index (pain, p = 0.543; function, p = 0.10; stiffness,
p = 0.99), Short Form-12 (physical component, p = 0.878; mental
component, p = 0.818) or Harris hip scores (p = 0.22). Radiological
outcomes revealed no significant wear in the ceramic group. Comparison of standard and highly cross-linked polyethylene,
however, revealed an almost threefold difference in the mean annual
linear wear rates (0.151 mm/year
We obtained pre-operative and six-month post-operative
Oxford hip (OHS) and knee scores (OKS) for 1523 patients who underwent
total hip replacement and 1784 patients who underwent total knee
replacement. They all also completed a six-month satisfaction question. Scatter plots showed no relationship between pre-operative Oxford
scores and six-month satisfaction scores. Spearman’s rank correlation
coefficients were -0.04 (95% confidence interval (CI) -0.09 to 0.01)
between OHS and satisfaction and 0.04 (95% CI -0.01 to 0.08) between
OKS and satisfaction. A receiver operating characteristic (ROC) curve
analysis was used to identify a cut-off point for the pre-operative
OHS/OKS that identifies whether or not a patient is satisfied with
surgery. We obtained an area under the ROC curve of 0.51 (95% CI
0.45 to 0.56) for hip replacement and 0.56 (95% CI 0.51 to 0.60)
for knee replacement, indicating that pre-operative Oxford scores
have no predictive accuracy in distinguishing satisfied from dissatisfied
patients. In the NHS widespread attempts are being made to use patient-reported
outcome measures (PROMs) data for the purpose of prioritising patients
for surgery. Oxford hip and knee scores have no predictive accuracy
in relation to post-operative patient satisfaction. This evidence
does not support their current use in prioritising access to care.
As part of the national initiative to reduce
waiting times for joint replacement surgery in Wales, the Cardiff
and Vale NHS Trust referred 224 patients to the NHS Treatment Centre
in Weston-Super-Mare for total knee replacement (TKR). A total of
258 Kinemax TKRs were performed between November 2004 and August
2006. Of these, a total of 199 patients (232 TKRs, 90%) have been
followed up for five years. This cohort was compared with 258 consecutive
TKRs in 250 patients, performed at Cardiff and Vale Orthopaedic
Centre (CAVOC) over a similar time period. The five year cumulative
survival rate was 80.6% (95% confidence interval (CI) 74.0 to 86.0)
in the Weston-Super-Mare cohort and 95.0% (95% CI 90.2 to 98.2)
in the CAVOC cohort with revision for any reason as the endpoint.
The relative risk for revision at Weston-Super-Mare compared with
CAVOC was 3.88 (p <
0.001). For implants surviving five years,
the mean Oxford knee scores (OKS) and mean EuroQol (EQ-5D) scores
were similar (OKS: Weston-Super-Mare 29 (2 to 47) The results show a higher revision rate for patients operated
at Weston-Super-Mare Treatment Centre, with a reduction in functional
outcome and quality of life after revision. This further confirms
that patients moved from one area to another for joint replacement
surgery fare poorly.
