Aim. Many aspects of the surgical treatment of patients with tuberculosis
(TB) of the spine, including the use of instrumentation and the
types of graft, remain controversial. Our aim was to report the
outcome of a single-stage posterior procedure, with or without posterior
decompression, in this group of patients. Patients and Methods. Between 2001 and 2010, 51 patients with a mean age of 62.5 years
(39 to 86) underwent long posterior instrumentation and short posterior
or posterolateral fusion for TB of the thoracic and lumbar spines,
followed by anti-TB chemotherapy for 12 months. No anterior debridement
of the necrotic tissue was undertaken. Posterior decompression with
laminectomy was carried out for the 30 patients with a neurological
deficit. Results. The mean kyphotic angle improved from 26.1° (- 1.8° to 62°) to
15.2° (-25° to 51°) immediately after the operation. At a mean follow-up
of 68.8 months (30 to 144) the mean kyphotic angle was 16.9° (-22°
to 54°), with a mean loss of correction of 1.6° (0° to 10°). There
was a mean improvement in neurological status of 1.2 Frankel grades
in those with a neurological deficit. Bony union was achieved in
all patients, without recurrent infection. Conclusions. Long posterior instrumentation with short posterior or posterolateral
fusion is effective in the treatment of TB spine. It controls infection,
corrects the kyphosis, and maintains correction and neurological
improvement over time. . Take home message: With effective anti-TB chemotherapy, a posterior
only procedure without
There have been few reports regarding the efficacy
of posterior instrumentation alone as surgical treatment for patients
with pyogenic spondylitis, thus avoiding the morbidity of anterior
surgery. We report the clinical outcomes of six patients with pyogenic
spondylitis treated effectively with a single-stage posterior fusion

Aims. Implant-related postoperative spondylodiscitis (IPOS) is a severe complication in spine surgery and is associated with high morbidity and mortality. With growing knowledge in the field of periprosthetic joint infection (PJI), equivalent investigations towards the management of implant-related infections of the spine are indispensable. To our knowledge, this study provides the largest description of cases of IPOS to date. Methods. Patients treated for IPOS from January 2006 to December 2020 were included. Patient demographics, parameters upon admission and discharge, radiological imaging, and microbiological results were retrieved from medical records. CT and MRI were analyzed for epidural, paravertebral, and intervertebral abscess formation, vertebral destruction, and endplate involvement. Pathogens were identified by CT-guided or intraoperative biopsy, intraoperative tissue sampling, or implant sonication. Results. A total of 32 cases of IPOS with a mean patient age of 68.7 years (37.6 to 84.1) were included. Diabetes, age > 60 years, and history of infection were identified as risk factors. Patient presentation upon admission included a mean body temperature of 36.7°C (36.1 to 38.0), back pain at rest (mean visual analogue scale (VAS) mean 5/10) and when mobile (mean VAS 6/10), as well as elevated levels of CRP (mean 76.8 mg/l (0.4 to 202.9)) and white blood cell count (mean 9.2 units/nl (2.6 to 32.8)). Pathogens were identified by CT-guided or conventional biopsy, intraoperative tissue sampling, or sonication, and Gram-positive cocci presented as the most common among them. Antibiotic therapy was established in all cases with pathogen-specific treatment in 23 (71.9%) subjects. Overall 27 (84.4%) patients received treatment by
A previously fit and well 58 year old male suffered from a bilateral psoas haematoma (PH) following 52 days of veno-venous extracorporeal membranous oxygenation (VV-ECMO) for severe Coronavirus disease (COVID-19), refractory to all non-invasive and medical therapies. He developed multiple complications, including inability to walk or weight-bear, due to lumbar plexopathy triggered by bilateral PH compression, compounded by COVID-19-related mononeuritis multiplex. The patient was referred to our institution with a known diagnosis of bilateral PH and after spinal multidisciplinary team (MDT) input, was deemed not for surgical or interventional radiology treatments. The patient received extensive neurorehabilitation, coordinated by multiple MDTs. Although PH has been correlated to COVID-19, to the best of our knowledge this is the first reported case of such a complex presentation resulting in a dramatic bilateral PH. Health records from 3 large UK teaching hospitals were collected regarding treatment and follow up appointments, following patient's written informed consent. Patient's comorbidities, duration in hospital units, MDT inputs, health assessments, mobilisation progress and neurologic assessments, were all recorded. Data was collected retrospectively then prospectively due to lengthy in-patient stay. The literature review was conducted via PubMed and open access sources, selecting all the relevant studies and the ECMO guidelines. Patient received treatment from 3 different units in 3 hospitals over 212 days including 103 days in neurorehabilitation. Involvement of physiotherapy, dietitians, speech and language teams, neurologist, neurophysiotherapists, occupational therapists was required. The patient progressed from a bed-bound coma and inability to walk, to standing with lower limb backslab at discharge. Additionally, he was referred for elective exploratory surgery of the psoas region for scar
Objectives. This presentation discusses the experience at our Centre with treating traumatic thoracolumbar fractures using percutaneous pedicle screw fixation and also looks at clinical and radiological outcomes as well as complications. Design. This is a retrospective study reviewing all cases performed between Jan 2013 and June 2019. Subjects. In our study there were 257 patients in total, of which there were 123 males and 134 females aged between 17 and 70. Methods. We reviewed the case notes and imaging retrospectively to obtain the relevant data. Results. A total of 257 patients were included, 123 males and 134 females; the mean age was 47.6 years. The majority of injuries were from fall from significant height. In 98 cases the fracture involved a thoracic vertebra and in 159 cases a lumbar vertebra. Percutaneous pedicle screw fixation was performed either one level above and below fracture or Two levels above and below the fracture depending upon the level of injury. Forty two cases were treated with additional short pedicle screws at the level of fracture. More than 15% (39) of patients presented with a neurological deficit on admission and more than 80% (32) of those showed post-operative improvement in their neurology as per Frankel Grading system. The mean Operative time was 117minutes +− 45, and mean length of hospital stay was 7.2 +− 3.8 days, with significant improvement in Visual analogue score. Percutaneous fixation achieved a satisfactory improvement in radiological parameters including sagittal Cobb angle (SCA) post-operatively in all patients. The vast majority of patients achieved a good functional outcome according to modified Macnab criteria. Follow up was for a maximum of two years, with relevant imaging at each stage. Ten (3.8%) patients had wound infection with three patients requiring wound
Closed suction subfascial drainage is widely used after instrumented posterior spinal fusion in patients with a spinal deformity. The aim of this study was to determine the effect of this wound drainage on the outcomes in patients with adolescent idiopathic scoliosis (AIS). This was a further analysis of a randomized, multicentre clinical trial reporting on patients after posterior spinal fusion using segmental pedicle screw instrumentation. In this study the incidence of deep surgical site infection (SSI) and chronic postoperative pain at two years’ follow-up are reported. We conducted a randomized, multicentre clinical trial on adolescents undergoing posterior spinal fusion for AIS using segmental pedicle screw instrumentation. A total of 90 consecutive patients were randomized into a ‘drain’ or ‘no drain’ group at the time of wound closure, using the sealed envelope technique (1:1). The primary outcomes in the initial study were the change in the level of haemoglobin in the blood postoperatively and total blood loss. A secondary outcome was the opioid consumption immediately after surgery. The aim of this further study was to report the rate of deep SSI and persistent postoperative pain, at two years' follow-up.Aims

This study evaluates the long-term survival of
spinal implants after surgical site infection (SSI) and the risk
factors associated with treatment failure. . A Kaplan-Meier survival analysis was carried out on 43 patients
who had undergone a posterior spinal fusion with instrumentation
between January 2006 and December 2008, and who consecutively developed
an acute deep surgical site infection. All were appropriately treated

The aim of this study was to evaluate whether, after correction of an adolescent idiopathic scoliosis (AIS), leaving out the subfascial drain gives results that are no worse than using a drain in terms of total blood loss, drop in haemoglobin level, and opioid consumption. Adolescents (aged between 10 and 21 years) with an idiopathic scoliosis (major curve ≥ 45°) were eligible for inclusion in this randomized controlled noninferiority trial (n = 125). A total of 90 adolescents who had undergone segmental pedicle screw instrumentation were randomized into no-drain or drain groups at the time of wound closure using the sealed envelope technique (1:1). The primary outcome was a drop in the haemoglobin level during first three postoperative days. Secondary outcomes were 48-hour postoperative oxycodone consumption and surgical complications.Aims

The outcome following the development of neurological complications after corrective surgery for scoliosis varies from full recovery to a permanent deficit. This study aimed to assess the prognosis and recovery of major neurological deficits in these patients, and to determine the risk factors for non-recovery, at a minimum follow-up of two years. A major neurological deficit was identified in 65 of 8,870 patients who underwent corrective surgery for scoliosis, including eight with complete paraplegia and 57 with incomplete paraplegia. There were 23 male and 42 female patients. Their mean age was 25.0 years (SD 16.3). The aetiology of the scoliosis was idiopathic (n = 6), congenital (n = 23), neuromuscular (n = 11), neurofibromatosis type 1 (n = 6), and others (n = 19). Neurological function was determined by the American Spinal Injury Association (ASIA) impairment scale at a mean follow-up of 45.4 months (SD 17.2). the patients were divided into those with recovery and those with no recovery according to the ASIA scale during follow-up.Aims

The aim of this study was to compare the clinical and radiological outcomes of patients with early-onset scoliosis (EOS), who had undergone spinal fusion after distraction-based spinal growth modulation using either traditional growing rods (TGRs) or magnetically controlled growing rods (MCGRs). We undertook a retrospective review of skeletally mature patients who had undergone fusion for an EOS, which had been previously treated using either TGRs or MCGRs. Measured outcomes included sequential coronal T1 to S1 height and major curve (Cobb) angle on plain radiographs and any complications requiring unplanned surgery before final fusion.Aims

Open discectomy (OD) is the standard operation for lumbar disc herniation (LDH). Percutaneous endoscopic lumbar discectomy (PELD), however, has shown similar outcomes to OD and there is increasing interest in this procedure. However despite improved surgical techniques and instrumentation, reoperation and infection rates continue and are reported to be between 6% and 24% and 0.7% and 16%, respectively. The objective of this study was to compare the rate of reoperation and infection within six months of patients being treated for LDH either by OD or PELD. In this retrospective, nationwide cohort study, the Korean National Health Insurance database from 1 January 2007 to 31 December 2018 was reviewed. Data were extracted for patients who underwent OD or PELD for LDH without a history of having undergone either procedure during the preceding year. Individual patients were followed for six months through their encrypted unique resident registration number. The primary endpoints were rates of reoperation and infection during the follow-up period. Other risk factors for reoperation and infection were also evalulated.Aims

Aims. Clinical and radiological data were reviewed for all patients
with mucopolysaccharidoses (MPS) with thoracolumbar kyphosis managed
non-operatively or operatively in our institution. Methods. In all 16 patients were included (eight female: eight male; 50%
male), of whom nine had Hurler, five Morquio and two Hunter syndrome.
Six patients were treated non-operatively (mean age at presentation
of 6.3 years; 0.4 to 12.9); mean kyphotic progression +1.5. o. /year;
mean follow-up of 3.1 years (1 to 5.1) and ten patients operatively (mean
age at presentation of 4.7 years; 0.9 to 14.4); mean kyphotic progression

patients with flexible deformities (n = 6). Results. In the surgical group (mean age at surgery of 6.6 years; 2.4
to 16.8); mean post-operative follow-up of 6.3 years (3.5 to 10.3),
mean pre-operative thoracolumbar kyphosis of 74.3. o. (42. o. to
110. o. ) was corrected to mean of 28.6. o. (0. o. to

To describe the clinical, radiological, and functional outcomes in patients with isolated congenital thoracolumbar kyphosis who were treated with three-column osteotomy by posterior-only approach. Hospital records of 27 patients with isolated congenital thoracolumbar kyphosis undergoing surgery at a single centre were retrospectively analyzed. All patients underwent deformity correction which involved a three-column osteotomy by single-stage posterior-only approach. Radiological parameters (local kyphosis angle (KA), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic tilt (PT), sacral slope (SS), C7 sagittal vertical axis (C7 SVA), T1 slope, and pelvic incidence minus lumbar lordosis (PI-LL)), functional scores, and clinical details of complications were recorded.Aims

Back ground:. The aim of this study is to evaluate the long-term outcome after posterior spinal stabilization surgery for the management of de novo non-tuberculous bacterial spinal infection. Method and Result:. Patients presenting to a single tertiary referral spinal centre between August 2011 and June 2014 were included in the study. 21 patients with nontuberculous bacterial infection were identified and included in the study. All patients were managed surgically with posterior stabilisation, with or without neural decompression, without
We studied 15 patients with healed tuberculosis of the spine and a resultant kyphosis. We selected only those with no neurological deficit and performed a wedge resection of the vertebra using a transpedicular approach. The wedge was removed from the apex of the deformity. For those with a neurological deficit, we chose the conventional anterior
The direct posterior approach with subperiosteal dissection of the paraspinal muscles from the vertebrae is considered to be the standard approach for the surgical treatment of adolescent idiopathic scoliosis (AIS). We investigated whether or not a minimally-invasive surgery (MIS) technique could offer improved results. Consecutive AIS patients treated with an MIS technique at two tertiary centres from June 2013 to March 2016 were retrospectively included. Preoperative patient deformity characteristics, perioperative parameters, power of deformity correction, and complications were studied. A total of 93 patients were included. The outcome of the first 25 patients and the latter 68 were compared as part of our safety analysis to examine the effect of the learning curve.Aims
Methods
The current trend in kyphosis correction is for “every level” instrumentation to achieve intraoperative stability, correction, fusion and implant longevity. We evaluate the medium term follow up of a low implant density (LID) construct. All patients with adolescent kyphosis (idiopathic or Scheurmann's) on our deformity database were identified. Radiographs and records were analysed for neurological complications, correction and revision. The constructs included were all pedicle screw anchors with multiple apical chevron osteotomies and a proximal and distal “box” of 6 to 8 screws. A four rod cantilever reduction manoeuvre with side to side connectors completed the construct. Kyphosis for any other cause was excluded. Follow up less than 12 months was excluded. 23 patients were identified with an average follow up 27 months (72 to 12 months) and a mean implant density of 1.1 (53.5% of “available” pedicles instrumented). There was 1 false positive neurophysiological event without sequelae (4%). There were no proximal junctional failures (0%). There were no pseudarthroses or rod breakages (0%). There was 1 loss of distal rod capture (early set screw failure) (4%). This was revised uneventfully. There were 4 infections requiring
To describe complications and reoperation rates associated with degenerative spinal deformity surgery. A retrospective review of prospectively collected data from a single spinal surgeon in the United Kingdom. A total of 107 patients who underwent surgery, of 5 or more levels, for primary degenerative kyphoscoliosis between 2006 and 2012 were identified. Clinical notes were reviewed and post-operative complications, reoperation rates, length of follow up and mortality were analysed. A total of 107 patients, average aged 66.5 years (range 52 – 85), with 80% women. 105 patients underwent posterior surgery, two patients required both anterior and posterior surgery. The average number of instrumented levels was 8.3; 10% 5 levels, 15% 6 levels, 11% 7 levels, 14% 8 levels, 15% 9 levels and 35% had fusions of 10 levels and above. 58% included fixation to sacrum or pelvis. 93% had a decompression performed and 30% had an osteotomy. There were 40 complications recorded within the follow-up period. Infection occurred in 7 patients (6.5%). All were successfully managed with
