The purpose of this study was to investigate the prevalence of
sarcopenia and to examine its impact on patients with degenerative
lumbar spinal stenosis (DLSS). This case-control study included two groups: one group consisting
of patients with DLSS and a second group of control subjects without
low back or neck pain and related leg pain. Five control cases were
randomly selected and matched by age and gender (n = 77 cases and
n = 385 controls) for each DLSS case. Appendicular muscle mass,
hand-grip strength, sit-to-stand test, timed up and go (TUG) test,
and clinical outcomes, including the Oswestry Disability Index (ODI)
scores and the EuroQol EQ-5D were compared between the two groups.Aims
Patients and Methods
Patient-reported outcome measures (PROMs) are
increasingly being used to assess functional outcome and patient satisfaction.
They provide a framework for comparisons between surgical units,
and individual surgeons for benchmarking and financial remuneration.
Better performance may bring the reward of more customers as patients and
commissioners seek out high performers for their elective procedures.
Using National Joint Registry (NJR) data linked to PROMs we identified
22 691 primary total knee replacements (TKRs) undertaken for osteoarthritis
in England and Wales between August 2008 and February 2011, and
identified the surgical factors that influenced the improvements
in the Oxford knee score (OKS) and EuroQol-5D (EQ-5D) assessment
using multiple regression analysis. After correction for patient
factors the only surgical factors that influenced PROMs were implant
brand and hospital type (both p <
0.001). However, the effects
of surgical factors upon the PROMs were modest compared with patient
factors. For both the OKS and the EQ-5D the most important factors
influencing the improvement in PROMs were the corresponding pre-operative
score and the patient’s general health status. Despite having only
a small effect on PROMs, this study has shown that both implant
brand and hospital type do influence reported subjective functional
scores following TKR. In the current climate of financial austerity,
proposed performance-based remuneration and wider patient choice,
it would seem unwise to ignore these effects and the influence of
a range of additional patient factors.
Our aim was to perform a systematic review of the literature
to assess the incidence of post-operative epidural haematomas and
wound infections after one-, or two-level, non-complex, lumbar surgery
for degenerative disease in patients with, or without post-operative
wound drainage. Studies were identified from PubMed and EMBASE, up to and including
27 August 2015, for papers describing one- or two-level lumbar discectomy
and/or laminectomy for degenerative disease in adults which reported
any form of subcutaneous or subfascial drainage.Aims

The April 2013 Shoulder &
Elbow Roundup360 looks at: biceps, pressure and instability; chronic acromio-clavicular joint instability; depression and shoulder pain; shoulder replacement and transfusion; cuff integrity and function; iatropathic plexus injury; the accuracy of acromio-clavicular joint injection; and tennis as a risk factor for tennis elbow.
The February 2014 Spine Roundup360 looks at: single posterior approach for severe kyphosis; risk factors for recurrent disc herniation; dysphagia and cervical disc replacement or fusion; hang on to your topical antibiotics; cost-effective lumbar disc replacement; anxiolytics no role to play in acute lumbar back pain; and surgery best for lumbar disc herniation.
The aim of this study was to compare the pain caused by the application
of a tourniquet after exsanguination of the upper limb with that
occurring after simple elevation. We used 26 healthy volunteers (52 arms), each of whom acted as
their own matched control. The primary outcome measure was the total pain experienced by
each volunteer while the tourniquet was inflated for 20 minutes.
This was calculated as the area under the pain curve for each individual
subject. Secondary outcomes were pain at each time point; the total
pain experienced during the recovery phase; the ability to tolerate the
tourniquet and the time for full recovery after deflation of the
tourniquet. Aims
Patients and Methods
Following arthroplasty of the knee, the patient’s
perception of improvement in symptoms is fundamental to the assessment
of outcome. Better clinical outcome may offset the inferior survival
observed for some types of implant. By examining linked National
Joint Registry (NJR) and patient-reported outcome measures (PROMs)
data, we aimed to compare PROMs collected at a minimum of six months
post-operatively for total (TKR: n = 23 393) and unicondylar knee
replacements (UKR: n = 505). Improvements in knee-specific (Oxford
knee score, OKS) and generic (EuroQol, EQ-5D) scores were compared
and adjusted for case-mix differences using multiple regression.
Whereas the improvements in the OKS and EQ-5D were significantly
greater for TKR than for UKR, once adjustments were made for case-mix
differences and pre-operative score, the improvements in the two
scores were not significantly different. The adjusted mean differences
in the improvement of OKS and EQ-5D were 0.0 (95% confidence interval (CI)
-0.9 to 0.9; p = 0.96) and 0.009 (95% CI -0.034 to 0.015; p = 0.37),
respectively. We found no difference in the improvement of either knee-specific
or general health outcomes between TKR and UKR in a large cohort
of registry patients. With concerns about significantly higher revision
rates for UKR observed in worldwide registries, we question the
widespread use of an arthroplasty that does not confer a significant
benefit in clinical outcome.
The optimal timing of total knee replacement
(TKR) in patients with osteoarthritis, in relation to the severity
of disease, remains controversial. This prospective study was performed
to investigate the effect of the severity of osteoarthritis and
other commonly available pre- and post-operative clinical parameters
on the clinical outcome in a consecutive series of cemented TKRs.
A total of 176 patients who underwent unilateral TKR were included
in the study. Their mean age was 68 years (39 to 91), 63 (36%) were
male and 131 knees (74%) were classified as grade 4 on the Kellgren–Lawrence
osteoarthritis scale. A total of 154 patients (87.5%) returned for
clinical review 12 months post-operatively, at which time the outcome
was assessed using the Knee Society score. A low radiological severity of osteoarthritis was not associated
with pain 12 months post-operatively. However, it was significantly
associated with an inferior level of function (p = 0.007), implying
the need for increased focus on all possible reasons for pain in
the knee and the forms of conservative treatment which are available
for patients with lower radiological severity of osteoarthritis. Cite this article:

The pre-operative level of haemoglobin is the strongest predictor
of the peri-operative requirement for blood transfusion after total
knee arthroplasty (TKA). There are, however, no studies reporting
a value that could be considered to be appropriate pre-operatively. This study aimed to identify threshold pre-operative levels of
haemoglobin that would predict the requirement for blood transfusion
in patients who undergo TKA. Analysis of receiver operator characteristic (ROC) curves of
2284 consecutive patients undergoing unilateral TKA was used to
determine gender specific thresholds predicting peri-operative transfusion
with the highest combined sensitivity and specificity (area under
ROC curve 0.79 for males; 0.78 for females).Aims

Recurrence of back or leg pain after discectomy
is a well-recognised problem with an incidence of up to 28%. Once conservative
measures have failed, several surgical options are available and
have been tried with varying degrees of success. In this study,
42 patients with recurrent symptoms after discectomy underwent less
invasive posterior lumbar interbody fusion (LI-PLIF). Clinical outcome
was measured using the Oswestry Disability Index (ODI), Short Form
36 (SF-36) questionnaires and visual analogue scales for back (VAS-BP)
and leg pain (VAS-LP). There was a statistically significant improvement
in all outcome measures (p <
0.001). The debate around which
procedure is the most effective for these patients remains controversial. Our results show that LI-PLIF is as effective as any other surgical
procedure. However, given that it is less invasive, we feel that
it should be considered as the preferred option.
The outcome after total hip replacement has improved
with the development of surgical techniques, better pain management
and the introduction of enhanced recovery pathways. These pathways
require a multidisciplinary team to manage pre-operative education,
multimodal pain control and accelerated rehabilitation. The current economic
climate and restricted budgets favour brief hospitalisation while
minimising costs. This has put considerable pressure on hospitals
to combine excellent results, early functional recovery and shorter
admissions. In this review we present an evidence-based summary of some common
interventions and methods, including pre-operative patient education,
pre-emptive analgesia, local infiltration analgesia, pre-operative
nutrition, the use of pulsed electromagnetic fields, peri-operative
rehabilitation, wound dressings, different surgical techniques, minimally
invasive surgery and fast-track joint replacement units. Cite this article:

A pragmatic multicentre randomised controlled trial (PROFHER)
was conducted in United Kingdom National Health Service (NHS) hospitals
to evaluate the clinical effectiveness and cost effectiveness of
surgery compared with non-surgical treatment for displaced fractures
of the proximal humerus involving the surgical neck in adults. A cost utility analysis from the NHS perspective was performed.
Differences between surgical and non-surgical treatment groups in
costs and quality adjusted life years (QALYs) at two years were
used to derive an estimate of the cost effectiveness of surgery
using regression methods. Aims
Methods
We have reviewed 22 patients at a mean of 30 years (28 to 31) after a whiplash injury. A complete recovery had been made in ten (45.5%) while one continued to describe severe symptoms. Persistent disability was associated with psychological distress but both improved in the period between 15 and 30 years after injury. After 30 years, ten patients (45.5%) were more disabled by knee than by neck pain.
There is a large amount of evidence available
about the relative merits of unicompartmental and total knee arthroplasty
(UKA and TKA). Based on the same evidence, different people draw
different conclusions and as a result, there is great variability
in the usage of UKA. The revision rate of UKA is much higher than TKA and so some
surgeons conclude that UKA should not be performed. Other surgeons
believe that the main reason for the high revision rate is that
UKA is easy to revise and, therefore, the threshold for revision
is low. They also believe that UKA has many advantages over TKA
such as a faster recovery, lower morbidity and mortality and better
function. They therefore conclude that UKA should be undertaken
whenever appropriate. The solution to this argument is to minimise the revision rate
of UKA, thereby addressing the main disadvantage of UKA. The evidence
suggests that this will be achieved if surgeons use UKA for at least
20% of their knee arthroplasties and use implants that are appropriate
for these broad indications. Cite this article:
