The aim of this retrospective study was to compare the correction achieved using a convex pedicle screw technique and a low implant density achieved using periapical concave-sided screws and a high implant density. We hypothesized that there would be no difference in outcome between the two techniques. We retrospectively analyzed a series of 51 patients with a thoracic adolescent idiopathic scoliosis. There were 26 patients in the convex pedicle screw group who had screws implanted periapically (Group 2) and a control group of 25 patients with bilateral pedicle screws (Group 1). The patients’ charts were reviewed and pre- and postoperative radiographs evaluated. Postoperative patient-reported outcome measures (PROMs) were recorded.Aims

During the pandemic of COVID-19, some patients with COVID-19 may need emergency surgeries. As spine surgeons, it is our responsibility to ensure appropriate treatment to the patients with COVID-19 and spinal diseases. A protocol for spinal surgery and related management on patients with COVID-19 has been reviewed. Patient preparation for emergency surgeries, indications, and contraindications of emergency surgeries, operating room preparation, infection control precautions and personal protective equipments (PPE), anesthesia management, intraoperative procedures, postoperative management, medical waste disposal, and surveillance of healthcare workers were reviewed. It should be safe for surgeons with PPE of protection level 2 to perform spinal surgeries on patients with COVID-19. Standardized and careful surgical procedures should be necessary to reduce the exposure to COVID-19.
The purpose of this study was to evaluate the incidence and analyze the trends of surgeon-reported complications following surgery for adolescent idiopathic scoliosis (AIS) over a 13-year period from the Scoliosis Research Society (SRS) Morbidity and Mortality database. All patients with AIS between ten and 18 years of age, entered into the SRS Morbidity and Mortality database between 2004 and 2016, were analyzed. All perioperative complications were evaluated for correlations with associated factors. Complication trends were analyzed by comparing the cohorts between 2004 to 2007 and 2013 to 2016.Aims
Methods
Iliac wing (Type I) and iliosacral (Type I/IV) pelvic resections for a primary bone tumour create a large segmental defect in the pelvic ring. The management of this defect is controversial as the surgeon may choose to reconstruct it or not. When no reconstruction is undertaken, the residual ilium collapses back onto the remaining sacrum forming an iliosacral pseudarthrosis. The aim of this study was to evaluate the long-term oncological outcome, complications, and functional outcome after pelvic resection without reconstruction. Between 1989 and 2015, 32 patients underwent a Type I or Type I/IV pelvic resection without reconstruction for a primary bone tumour. There were 21 men and 11 women with a mean age of 35 years (15 to 85). The most common diagnosis was chondrosarcoma (50%, n = 16). Local recurrence-free, metastasis-free, and overall survival were assessed using the Kaplan-Meier method. Patient function was evaluated using the Musculoskeletal Tumour Society (MSTS) and Toronto Extremity Salvage Score (TESS).Aims
Methods
We carried out an MRI study of the lumbar spine in 15 patients with achondroplasia to evaluate the degree of stenosis of the canal. They were divided into asymptomatic and symptomatic groups. We measured the sagittal canal diameter, the sagittal cord diameter, the interpedicular distance at the mid-pedicle level and the cross-sectional area of the canal and spinal cord at mid-body and mid-disc levels. The MRI findings showed that in achondroplasia there was a significant difference between the groups in the cross-sectional area of the body canal at the upper lumbar levels. Patients with a narrower canal are more likely to develop symptoms of spinal stenosis than others.
The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression. The medical records of 135 patients with complete paralysis due to neoplastic cord compression were retrospectively reviewed. Potential factors including the timing of surgery, muscular tone, and tumour characteristics were analyzed in relation to neurological recovery using logistical regression analysis. The association between neurological recovery and survival was analyzed using a Cox model. A nomogram was formulated to predict recovery.Aims
Patients and Methods
Neurogenic claudication is most frequently observed
in patients with degenerative lumbar spinal stenosis. We describe
a patient with lumbar epidural varices secondary to obstruction
of the inferior vena cava by pathological lymph nodes presenting
with this syndrome. Following a diagnosis of follicular lymphoma,
successful chemotherapy led to the resolution of the varices and
the symptoms of neurogenic claudication. The lumbar epidural venous plexus may have an important role
in the pathogenesis of spinal stenosis. Although rare, epidural
venous engorgement can induce neurogenic claudication without spinal
stenosis. Further investigations should be directed at identifying
an underlying cause.
The indications for lumbar discectomy are pain and neurological dysfunction. This paper considers the extent and timing of neurological recovery following spinal decompression.
Our aim in this paper was to investigate the
guidelines and laws governing informed consent in the English-speaking
world. We noted a recent divergence from medical paternalism within
the United Kingdom, highlighted by the Montgomery v Lanarkshire Health
Board ruling of 2015. We investigated the situation in the United
Kingdom, Australia, New Zealand, Canada, and the United States of
America. We read the national guidance regarding obtaining consent
for surgical intervention for each country. We used the references
from this guidance to identify the laws that helped inform the guidance,
and reviewed the court documents for each case. There has been a trend towards a more patient-focused approach
in consent in each country. Surgeons should be aware of the guidance
and legal cases so that they can inform patients fully, and prevent
legal problems if outdated practices are followed. Cite this article:
The aim of this study was to determine the efficacy of repeat epidural steroid injections as a form of treatment for patients with insufficiently controlled or recurrent radicular pain due to a lumbar or cervical disc herniation. A cohort of 102 patients was prospectively followed, after an epidural steroid injection for radicular symptoms due to lumbar disc herniation, in 57 patients, and cervical disc herniation, in 45 patients. Those patients with persistent pain who requested a second injection were prospectively followed for one year. Radicular and local pain were assessed on a visual analogue scale (VAS), functional outcome with the Oswestry Disability Index (ODI) or the Neck Pain and Disability Index (NPAD), as well as health-related quality of life (HRQoL) using the 12-Item Short-Form Health Survey questionnaire (SF-12).Aims
Patients and Methods
Adolescent idiopathic scoliosis (AIS) is a complex
3D deformity of the spine. Its prevalence is between 2% and 3% in the
general population, with almost 10% of patients requiring some form
of treatment and up to 0.1% undergoing surgery. The cosmetic aspect
of the deformity is the biggest concern to the patient and is often
accompanied by psychosocial distress. In addition, severe curves
can cause cardiopulmonary distress. With proven benefits from surgery,
the aims of treatment are to improve the cosmetic and functional
outcomes. Obtaining correction in the coronal plane is not the only
important endpoint anymore. With better understanding of spinal
biomechanics and the long-term effects of multiplanar imbalance,
we now know that sagittal balance is equally, if not more, important.
Better correction of deformities has also been facilitated by an
improvement in the design of implants and a better understanding
of metallurgy. Understanding the unique character of each deformity
is important. In addition, using the most appropriate implant and
applying all the principles of correction in a bespoke manner is important
to achieve optimum correction. In this article, we review the current concepts in AIS surgery. Cite this article:
The outcome of surgery for recurrent lumbar disc
herniation is debatable. Some studies show results that are comparable
with those of primary discectomy, whereas others report worse outcomes.
The purpose of this study was to compare the outcome of revision
lumbar discectomy with that of primary discectomy in the same cohort
of patients who had both the primary and the recurrent herniation
at the same level and side. A retrospective analysis of prospectively gathered data was undertaken
in 30 patients who had undergone both primary and revision surgery
for late recurrent lumbar disc herniation. The outcome measures
used were visual analogue scales for lower limb (VAL) and back (VAB)
pain and the Oswestry Disability Index (ODI). There was a significant improvement in the mean VAL and ODI scores
(both p <
0.001) after primary discectomy. Revision surgery also
resulted in improvements in the mean VAL (p <
0.001), VAB (p
= 0.030) and ODI scores (p <
0.001). The changes were similar
in the two groups (all p >
0.05). Revision discectomy can give results that are as good as those
seen after primary surgery. Cite this article:
Many hospitals do not have a structured process
of consent, the attainment of which can often be rather ‘last-minute’
and somewhat chaotic. This is a surprising state of affairs as spinal
surgery is a high-risk surgical specialty with potential for expensive
litigation claims. More recently, the Montgomery ruling by the United
Kingdom Supreme Court has placed the subject of informed consent
into the spotlight. There is a paucity of practical guidance on how a consent process
can be achieved in a busy clinical setting. The British Association
of Spinal Surgeons (BASS) has convened a working party to address
this need. To our knowledge this is the first example of a national
professional body, representing a single surgical specialty, taking such
a fundamental initiative. In a hard-pressed clinical environment, the ability to achieve
admission reliably on the day of surgery, in patients at ease with
their situation and with little likelihood of late cancellation,
will be of great benefit. It will reduce litigation and improve
the patient experience. Cite this article:
