With recent progress in cancer treatment, the number of advanced-age patients with spinal metastases has been increasing. It is important to clarify the influence of advanced age on outcomes following surgery for spinal metastases, especially with a focus on subjective health state values. We prospectively analyzed 101 patients with spinal metastases who underwent palliative surgery from 2013 to 2016. These patients were divided into two groups based on age (< 70 years and ≥ 70 years). The Eastern Cooperative Oncology Group (ECOG) performance status (PS), Barthel index (BI), and EuroQol-5 dimension (EQ-5D) score were assessed at study enrolment and at one, three, and six months after surgery. The survival times and complications were also collected.Aims
Methods
This study aimed to determine the relationship between pedicle-lengthening
distance and bulge-canal volume ratio in cases of lumbar spinal
stenosis, to provide a theoretical basis for the extent of lengthening
in pedicle-lengthening osteotomies. Three-dimensional reconstructions of CT images were performed
for 69 patients (33 men and 36 women) (mean age 49.96 years; 24
to 81). Simulated pedicle-lengthening osteotomies and disc bulge
and spinal canal volume calculations were performed using Mimics
software. Aims
Methods
The aim of this study was to compare the peak pull-out force
(PPF) of pedicle-lengthening screws (PLS) and traditional pedicle
screws (TPS) using instant and cyclic fatigue testing. A total of 60 lumbar vertebrae were divided into six groups:
PLS submitted to instant pull-out and fatigue-resistance testing
(groups A1 and A2, respectively), TPS submitted to instant pull-out
and fatigue-resistance testing (groups B1 and B2, respectively)
and PLS augmented with 2 ml polymethylmethacrylate, submitted to
instant pull-out and fatigue-resistance testing (groups C1 and C2,
respectively). The PPF and normalized PPF (PPFn) for bone mineral density
(BMD) were compared within and between all groups.Aims
Materials and Methods
The objective of this study was to assess the association between whole body sagittal balance and risk of falls in elderly patients who have sought treatment for back pain. Balanced spinal sagittal alignment is known to be important for the prevention of falls. However, spinal sagittal imbalance can be markedly compensated by the lower extremities, and whole body sagittal balance including the lower extremities should be assessed to evaluate actual imbalances related to falls. Patients over 70 years old who visited an outpatient clinic for back pain treatment and underwent a standing whole-body radiograph were enrolled. Falls were prospectively assessed for 12 months using a monthly fall diary, and patients were divided into fallers and non-fallers according to the history of falls. Radiological parameters from whole-body radiographs and clinical data were compared between the two groups.Objectives
Methods
The aim of this study was to investigate the clinical and radiographic
outcomes of microendoscopic laminotomy in patients with lumbar stenosis
and concurrent degenerative spondylolisthesis (DS), and to determine
the effect of this procedure on spinal stability. A total of 304 consecutive patients with single-level lumbar
DS with concomitant stenosis underwent microendoscopic laminotomy
without fusion between January 2004 and December 2010. Patients
were divided into two groups, those with and without advanced DS
based on the degree of spondylolisthesis and dynamic instability. A
total of 242 patients met the inclusion criteria. There were 101
men and 141 women. Their mean age was 68.1 years (46 to 85). Outcome
was assessed using the Japanese Orthopaedic Association and Roland
Morris Disability Questionnaire scores, a visual analogue score
for pain and the Short Form Health-36 score. The radiographic outcome
was assessed by measuring the slip and the disc height. The clinical
and radiographic parameters were evaluated at a mean follow-up of
4.6 years (3 to 7.5).Aims
Patients and Methods
There have been a few reports of patients with
a combination of lumbar and thoracic spinal stenosis. We describe six
patients who suffered unexpected acute neurological deterioration
at a mean of 7.8 days (6 to 10) after lumbar decompressive surgery.
Five had progressive weakness and one had recurrent pain in the
lower limbs. There was incomplete recovery following subsequent
thoracic decompressive surgery. The neurological presentation can be confusing. Patients with
compressive myelopathy due to lower thoracic lesions, especially
epiconus lesions (T10 to T12/L1 disc level), present with similar
symptoms to those with lumbar radiculopathy or cauda equina lesions.
Despite the rarity of this condition we advise that patients who
undergo lumbar decompressive surgery for stenosis should have sagittal
whole spine MRI studies pre-operatively to exclude proximal neurological
compression. Cite this article:
Although vertebroplasty is very effective for relieving acute pain from an osteoporotic vertebral compression fracture, not all patients who undergo vertebroplasty receive the same degree of benefit from the procedure. In order to identify the ideal candidate for vertebroplasty, pre-operative prognostic demographic or clinico-radiological factors need to be identified. The objective of this study was to identify the pre-operative prognostic factors related to the effect of vertebroplasty on acute pain control using a cohort of surgically and non-surgically managed patients. Patients with single-level acute osteoporotic vertebral compression fracture at thoracolumbar junction (T10 to L2) were followed. If the patients were not satisfied with acute pain reduction after a three-week conservative treatment, vertebroplasty was recommended. Pain assessment was carried out at the time of diagnosis, as well as three, four, six, and 12 weeks after the diagnosis. The effect of vertebroplasty, compared with conservative treatment, on back pain (visual analogue score, VAS) was analysed with the use of analysis-of-covariance models that adjusted for pre-operative VAS scores.Objectives
Patients and Methods
We compared the clinical and radiological outcomes of using a
polyetheretherketone cage with (TiPEEK) and without a titanium coating
(PEEK) for instrumented transforaminal lumbar interbody fusion (TLIF). We conducted a randomised clinical pilot trial of 40 patients
who were scheduled to undergo a TLIF procedure at one or two levels
between L2 and L5. The Oswestry disability index (ODI), EuroQoL-5D,
and back and leg pain were determined pre-operatively, and at three,
six, and 12 months post-operatively. Fusion rates were assessed
by thin slice CT at three months and by functional radiography at
12 months.Aims
Materials and Methods
The aims of this study were to describe the prevalence of previous
lumbar surgery in patients who undergo total hip arthroplasty (THA)
and to investigate their patient-reported outcomes (PROMs) one year
post-operatively. Data from the Swedish Hip Arthroplasty Register and the Swedish
Spine Register gathered from 2002 to 2013 were merged to identify
a group of patients who had undergone lumbar surgery before THA
(n = 997) and a carefully matched one-to-one control group. We investigated
differences in the one-year post-operative PROMs between the groups.
Linear regression analyses were used to explore the associations
between previous lumbar surgery and these PROMs following THA. The
prevalence of prior lumbar surgery was calculated as the ratio of
patients identified with previous lumbar surgery between 2002 and
2012, and divided by the total number of patients who underwent
a THA in 2012.Aims
Patients and Methods
The February 2013 Spine Roundup360 looks at: complications with anterior decompression and fusion; lumbar claudication and peripheral vascular disease; increasing cervical instability in rheumatoids; kyphoplasty; cervical stenosis; exercise or fusion for chronic lower back pain; lumbar disc arthroplasty and adjacent level changes; and obese disc prolapses.
