Discuss or comment on this article.
Abstract Vertebral endplate signal changes (VESC), also known as Modic changes, have been reported to be associated with low back pain
(LBP). However, little is known about predisposing factors for the development of new VESC. The aim of this study was to investigate
the predictive value of lifestyle factors and disc-related magnetic resonance imaging (MRI) findings in relation to the development
of new VESC. This prospective observational study included 344 people from the Danish general population who had an MRI and
completed LBP questionnaires at the age of 40 and again at 44 years. Potential predict...

Abstract Recurrent low back pain (recurrent LBP) is a common condition, however, it is unclear if uniform definitions are used in studies
investigating the prevalence and management of this condition. The aim of this systematic review was to identify how recurrent
LBP is defined in the literature. A literature search was performed on MEDLINE, EMBASE, CINAHL, AMED, and PEDro. Studies were
considered eligible if they investigated a cohort of subjects with recurrent LBP or if they were measuring the prevalence
of recurrent LBP. Two independent reviewers assessed inclusion of studies and extracted definitions of...

Discuss or comment on this article.
In conclusion,
high success rate of subaxial cervical pedicle screw placement can be achieved using the recently proposed operative guideline
and oblique views of fluoroscopy. However, careful preoperative planning and good surgical skills are still required to ensure
screw placement accuracy and to reduce the risk of neural and vascular injury.

Abstract Lumbar disc herniation (LDH) is a common disorder among adults with degenerated lumbar intervertebral discs. However, its
occurrence in childhood and adolescence is much less frequent mostly because children and adolescents tend to have a healthier
lumbar spine as compared with adults. This difference indicates that children and adolescents are far from being just little
adults. Over the years, there have constantly been published studies concerning this entity where the findings suggested that
pediatric LDH is, in many ways, different from that in adults. To date, the prevalence, the etiological an...

Abstract Posterior corrective surgery using “all pedicle screw construct” carries risk of neurovascular complications. The study aims
were to assess the screw placement in patients with adolescent idiopathic scoliosis using CT with low-radiation dose, and
to evaluate the clinical outcome in patients with misplaced pedicle screws. CTs of 49 consecutive patients (873 screws, 79%
thoracic) were retrospectively evaluated by two independent radiologists. A new grading system was developed to distinguish
between lateral, medial and anterior cortical perforations, endplate perforation and foraminal perforation....

Abstract Intraradicular lumbar disc herniation is a rare complication of disc disease that is generally diagnosed only during surgery.
The mechanism for herniated disc penetration into the intradural space is not known with certainty, but adhesion between the
radicular dura and the posterior longitudinal ligament was suggested as the most important condition. The authors report the
first case of an intraradicular lumbar disc herniation without subdural penetration; the disc hernia was lodged between the
two radicular dura layers. The patient, a 34-year-old soldier, was admitted with a 12-month history of low...

Abstract Randomised controlled trials (RCTs) of cervical disc arthroplasty vs fusion generally show slightly more favourable results
for arthroplasty. However, RCTs in surgery often have limited external validity, since they involve a select group of patients
who fit very rigid admission criteria and who are prepared to subject themselves to randomisation. The aim of this study was
to examine whether the findings of RCTs are verified by observational data recorded in our Spine Center in association with
the Spine Society of Europe Spine Tango surgical registry. Patients undergoing fusion/stabilisation or dis...

Abstract With regard to the literature, several factors are considered to have an impact on postoperative mobility after lumbar total

height and ligamentous integrity have also an influence on biomechanics of a treated segment. The purpose of the study was
to evaluate the influence of posterior longitudinal ligament (PLL) resection and segmental distraction on range of motion
(ROM). Six human, lumbar spines (L2–L3) were tested with pure moments of ±7.5 Nm in a spine loading ap...

Abstract Spinal epidural hematoma (SEH) represents the most frequent entity of acute or chronic spinal bleeding. Based upon pathogenesis,
SEH can be classified as idiopathic, spontaneous, and secondary. The idiopathic forms are considered not to be attributed
to any specific risk factors. Spontaneous SEH, accounting for 0.3–0.9% of all spinal epidural space occupying lesions, instead
is associated with risk factors (such as substantial soft trauma or coagulation abnormalities). The chronic form, as our literature
review revealed, is the rarest and its most frequent location is the lumbar spine. The pathoph...

Abstract A classification of injuries is necessary in order to develop a common language for treatment indications and outcomes. Several

system is that it is based on an assumption, which is anatomically unidentifiable: the so-called middle column. For this reason,
few years ago, a group of spine surgeons has developed a new classification system, which is based on the severity of the
injury. The severity is defined by the pathomorphological findings, the prognosis in terms of h...

Abstract For an individual, the functional consequences of an episode of low back pain is a key measure of their clinical status. Self-reported
disability measures are commonly used to capture this component of the back pain experience. In non-acute low back pain there
is some uncertainty of the validity of this approach. It appears that self-reported assessment of disability and direct measurements
of functional status are only moderately related. In this cross-sectional study, we investigated this relationship in a sample

also affected by DISH. Approximately 3 years later, the patient sustained a whiplash injury in a low impact car accident,
resulting in a C3–C4 fracture dislocation, which was not immediately diagnosed because he did not seek medic...

Double approach in thoraco-lumbar malunionsEmail this article to a colleague.

Discuss or comment on this article.
Abstract Thoracolumbar fractures (T11–L2) complicated by malunion often need surgery. In our hands two approaches are necessary for
release and fusion. Correction is obtained by posterior bending in situ of a screw rod fixation. When the deformity is flexible,
first we perform a posterior reduction and stabilization, and secondly an anterior approach for interbody fusion. When spine
is rigid an anterior release with waiting bone graft is performed first followed by a second posterior reduction and stabilization.
This strategy allows a real correction without the loss of correction in time. This technique i...

Percutaneous posterior-lateral lumbar interbody fusion for degenerative disc disease using a B-Twin expandable spinal spacerEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Abstract Degenerative disc disease (DDD) causes gradual intervertebral space collapse, concurrent discogenic or facet-induced pain,
and possible compression radiculopathy. A new minimal invasion procedure of percutaneous posterior-lateral lumbar interbody
fusion (PPLIF) using a B-Twin stand-alone expandable spinal spacer (ESS) was designed to treat this disease and evaluated
by follow-up more than 1 year. 12 cases with chronic low back pain and compressive radiculopathy due to DDD refractory were
selected to conservative treatment. Under fluoroscopy in the posterior-lateral position, a K-wire was advanc...

Laser-evoked potentials: prognostic relevance of pain pathway defects in patients with acute radiculopathyEmail this article to a colleague.

Discuss or comment on this article.
Abstract The radicular pain syndrome is a major problem in public health care that can lead to chronic back and leg pain in 30%. Ischalgia
and back pain are the most prominent signs of dorsal root affection. Until now, no clinical or neurophysiological test procedure
exists that evaluates the function of the dorsal root and predicts the prognosis of patients suffering from RPS. We have recently
demonstrated that laser-evoked potentials (LEP) are able to demonstrate dorsal root damage. With this study, we investigated
54 patients with acute radicular symptoms and compared LEP parameters (side to side differen...

Differentiation between deep and superficial fibers of the lumbar multifidus by magnetic resonance imagingEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
In conclusion, this study demonstrates a higher T2 relaxation time in the deep
portion, which supports the current assumption that the deep multifidus has a higher percentage of slow twitch fibers compared
to the superficial multifidus. No differential recruitment has been found following trunk extension with and without pain
induction. For further research, it would be interesting to investigate a clinical LBP population, using this non-invasive
muscle functional MRI approach.

The association between isoinertial trunk muscle performance and low back pain in male adolescentsEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
Abstract The literature reports inconsistent findings regarding the association between low back pain (LBP) and trunk muscle function,
in both adults and children. The strength of the relationship appears to be influenced by how LBP is qualified and the means
by which muscle function is measured. The aim of this study was to examine the association between isoinertial trunk muscle
performance and consequential (non-trivial) low back pain (LBP) in male adolescents. Healthy male adolescents underwent anthropometric
measurements, clinical evaluation, and tests of trunk range of motion (ROM), maximum isometric s...

Cauda equina lesions as a complication of spinal surgeryEmail this article to a colleague.
Save this article to My Clippings.
Discuss or comment on this article.
In conclusion the study identified spinal surgery as the cause of approximately 15% of cauda equina lesions. More than a third
of lesions developed after procedures performed by a single surgeon. Most of the remaining lesions could probably be avoided
by better surgical technique (e.g. the use of a high-speed drill instead of a Kerrison rongeur in patients with severe spinal
stenosis), or prevented by closer postoperative monitoring (e.g. in patients with postoperative lumbar epidural haematoma).

Abstract This is a radiographic study of ankylosing spondylitis patients with severe fixed kyphotic deformity who underwent pedicle
subtraction osteotomy. Our goal was to measure and validate new angle to assess global kyphosis and to evaluate the radiological
outcomes after surgery. This is the first report which describes new angle to assess global kyphosis (T1-S1). Pre and postoperative
controls were compared according to the Pelvic Incidence. The sagittal parameters ankylosing spondylitis patients were compared
with 154 asymptomatic patients. In addition to the pelvic parameters and the C7 tilt, we used ...

Abstract A prospective, randomized, controlled study was carried out to compare the radiological and clinical outcomes after anterior
cervical decompression and fusion (ACDF) with Trabecular Metal™ (TM) to the traditional Smith–Robinson (SR) procedure with autograft. The clinical results of cervical fusion with autograft
from the iliac crest are typically satisfactory, but implications from the donor site are frequently reported. Alternative
materials for cervical body interfusion have shown lower fusion rates. Trabecular Metal is a porous tantalum biomaterial with structure and mechanical properties simi...

Discuss or comment on this article.
Abstract Intradural spinal arachnoid cysts with cord compression are rare. When becoming symptomatic they cause variable symptoms involving
gait disturbance, paraparesis or tetraparesis and neuropathic pain, decreasing significantly the patients’ life quality. The
extension of such cysts averages 3.7 vertebral bodies. The diagnosis is clinical and radiological with the use of MRI, CT
myelography or a combination of both. The best treatment option is complete removal of the cyst. However, even when paresis
is regressing there is no good recovery from neuropathic pain. Laminectomy approach can cause postoper...
