Total Of the 54 patients who underwent TES for a primary tumour between
1993 and 2010, 19 died and four were lost to follow-up. In January
2012, a questionnaire was sent to the 31 surviving patients. This
included the short form-36 to assess HRQoL and questions about the
current condition of their disease, activities of daily living (ADL)
and surgery. The response rate was high at 83.9% (26/31 patients).
We found that most patients were satisfied and maintained good performance
of their ADLs. The mental health status and social roles of the HRQoL scores
were nearly equivalent to those of healthy individuals, regardless
of the time since surgery. There was significant impairment of physical
health in the early post-operative years, but this usually returned
to normal approximately three years after surgery. Cite this article:
To assess the sustainability of our institutional
bone bank, we calculated the final product cost of fresh-frozen femoral
head allografts and compared these costs with the use of commercial
alternatives. Between 2007 and 2010 all quantifiable costs associated
with allograft donor screening, harvesting, storage, and administration
of femoral head allografts retrieved from patients undergoing elective
hip replacement were analysed. From 290 femoral head allografts harvested and stored as full
(complete) head specimens or as two halves, 101 had to be withdrawn.
In total, 104 full and 75 half heads were implanted in 152 recipients.
The calculated final product costs were €1367 per full head. Compared
with the use of commercially available processed allografts, a saving
of at least €43 119 was realised over four-years (€10 780 per year)
resulting in a cost-effective intervention at our institution. Assuming
a price of between €1672 and €2149 per commercially purchased allograft,
breakeven analysis revealed that implanting between 34 and 63 allografts
per year equated to the total cost of bone banking. Cite this article:
This study assessed the effect of concomitant
back pain on the Oxford knee score (OKS), Short-Form (SF)-12 and patient
satisfaction after total knee replacement (TKR). It involved a prospectively
compiled database of demographics and outcome scores for 2392 patients
undergoing primary TKR, of whom 829 patients (35%) reported back
pain. Compared with those patients without back pain, those with
back pain were more likely to be female (odds ratio (OR) 1.5 (95%
confidence interval (CI) 1.3 to 1.8)), have a greater level of comorbidity,
a worse pre-operative OKS (2.3 points (95% CI 1.7 to 3.0)) and worse
SF-12 physical (2.0 points (95% CI 1.4 to 2.6)) and mental (3.3
points (95% CI 2.3 to 4.3)) components. One year post-operatively, those with back pain had significantly
worse outcome scores than those without with a mean difference in
the OKS of 5 points (95% CI 3.8 to 5.4), in the SF-12 physical component
of 6 points (95% CI 5.4 to 7.1) and in the mental component of
4 points (95% CI 3.1 to 4.9). Patients with back pain were less
likely to be satisfied (OR 0.62, 95% CI 0.5 to 0.78). After adjusting for confounding variables, concomitant back pain
was an independent predictor of a worse post-operative OKS, and
of dissatisfaction. Clinicians should be aware that patients suffering
concomitant back pain pre-operatively are at an increased risk of
being dissatisfied post-operatively. Cite this article:

We reviewed 59 bone graft substitutes marketed
by 17 companies currently available for implantation in the United Kingdom,
with the aim of assessing the peer-reviewed literature to facilitate
informed decision-making regarding their use in clinical practice.
After critical analysis of the literature, only 22 products (37%)
had any clinical data. Norian SRS (Synthes), Vitoss (Orthovita),
Cortoss (Orthovita) and Alpha-BSM (Etex) had Level I evidence. We question
the need for so many different products, especially with limited
published clinical evidence for their efficacy, and conclude that
there is a considerable need for further prospective randomised
trials to facilitate informed decision-making with regard to the
use of current and future bone graft substitutes in clinical practice. Cite this article:

We retrospectively examined the prevalence and
natural history of asymptomatic lumbar canal stenosis in patients treated
surgically for cervical compressive myelopathy in order to assess
the influence of latent lumbar canal stenosis on the recovery after
surgery. Of 214 patients who had undergone cervical laminoplasty
for cervical myelopathy, we identified 69 (32%) with myelographically
documented lumbar canal stenosis. Of these, 28 (13%) patients with
symptomatic lumbar canal stenosis underwent simultaneous cervical
and lumbar decompression. Of the remaining 41 (19%) patients with
asymptomatic lumbar canal stenosis who underwent only cervical surgery,
39 were followed up for ≥ 1 year (mean 4.9 years (1 to 12)) and
were included in the analysis (study group). Patients without myelographic
evidence of lumbar canal stenosis, who had been followed up for ≥ 1
year after the cervical surgery, served as controls (135 patients;
mean follow-up period 6.5 years (1 to 17)). Among the 39 patients
with asymptomatic lumbar canal stenosis, seven had lumbar-related
leg symptoms after the cervical surgery. Kaplan–Meier analysis showed that 89.6% (95% confidence interval
(CI) 75.3 to 96.0) and 76.7% (95% CI 53.7 to 90.3) of the patients
with asymptomatic lumbar canal stenosis were free from leg symptoms
for three and five years, respectively. There were no significant
differences between the study and control groups in the recovery
rate measured by the Japanese Orthopaedic Association score or improvement
in the Nurick score at one year after surgery or at the final follow-up. These results suggest that latent lumbar canal stenosis does
not influence recovery following surgery for cervical myelopathy;
moreover, prophylactic lumbar decompression does not appear to be
warranted as a routine procedure for coexistent asymptomatic lumbar
canal stenosis in patients with cervical myelopathy, when planning
cervical surgery.
There is currently no consensus about the mean
volume of blood lost during spinal tumour surgery and surgery for metastatic
spinal disease. We conducted a systematic review of papers published
in the English language between 31 January 1992 and 31 January 2012.
Only papers that clearly presented blood loss data in spinal surgery
for metastatic disease were included. The random effects model was
used to obtain the pooled estimate of mean blood loss. We selected 18 papers, including six case series, ten retrospective
reviews and two prospective studies. Altogether, there were 760
patients who had undergone spinal tumour surgery and surgery for
metastatic spinal disease. The pooled estimate of peri-operative
blood loss was 2180 ml (95% confidence interval 1805 to 2554) with catastrophic
blood loss as high as 5000 ml, which is rare. Aside from two studies
that reported large amounts of mean blood loss (>
5500 ml), the
resulting funnel plot suggested an absence of publication bias.
This was confirmed by Egger’s test, which did not show any small-study
effects
(p = 0.119). However, there was strong evidence of heterogeneity
between studies (I2 = 90%; p <
0.001). Spinal surgery for metastatic disease is associated with significant
blood loss and the possibility of catastrophic blood loss. There
is a need to establish standardised methods of calculating and reporting
this blood loss. Analysis should include assessment by area of the
spine, primary pathology and nature of surgery so that the amount
of blood loss can be predicted. Consideration should be given to
autotransfusion in these patients. Cite this article:
We investigated the pre-operative and one-year post-operative health-related quality of life (HRQoL) outcome by using a Euroqol (EQ-5D) questionnaire in 230 patients who underwent surgery for lumbar spinal stenosis. Data were obtained from the National Swedish Registry for operations on the lumbar spine between 2001 and 2002. We analysed the pre- and postoperative quality of life data, age, gender, smoking habits, pain and walking ability. The relative differences were compared to a Swedish EQ-5D population survey. The mean age of the patients was 66 years, and there were 123 females (53%). Before the operation 62 (27%) of the patients could walk more than 500 m. One year after the operation 150 (65%) were able to walk 500 m or more. The mean EQ-5D score improved from 0.36 to 0.64, and the HRQoL improved in 184 (80%) of the patients. However, they did not reach the level reported by a matched population sample (mean difference 0.18). Women had lower pre- and post-operative EQ-5D scores than men. Severe low back pain was a predictor for a poor outcome.
In a prospective observational study we compared the two-year outcome of lumbar fusion by a simple technique using translaminar screws (n = 57) with a more extensive method using transforaminal lumbar interbody fusion and pedicular screw fixation (n = 63) in consecutive patients with degenerative disease of the lumbar spine. Outcome was assessed using the validated multidimensional Core Outcome Measures Index. Blood loss and operating time were significantly lower in the translaminar screw group (p <
0.01). The complication rates were similar in each group (2% to 4%). In all, 91% of the patients returned their questionnaire at two-years. The groups did not differ in Core Outcome Measures Index score reduction, 3.6 ( The two fusion techniques differed markedly in their extent and the cost of the implants, but were associated with almost identical patient-orientated outcomes. Extensive three-point stabilisation is not always required to achieve satisfactory patient-orientated results at two years.
