Aims. To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele. Methods. We reviewed 12 consecutive patients (7M:5F; mean age 12.4 years (9.2 to 16.8)) including demographic details, spinopelvic parameters, surgical correction, and perioperative data. We assessed the impact of surgery on patient outcomes using the Spina Bifida Spine Questionnaire and a qualitative questionnaire. Results. The mean follow-up was 5.4 years (2 to 14.9). Nine patients had kyphoscoliosis, two lordoscoliosis, and one kyphosis. All patients had a thoracolumbar deformity. Mean scoliosis corrected from 89.6° (47° to 151°) to 46.5° (17° to 85°; p < 0.001). Mean kyphosis corrected from 79.5° (40° to 135°) to 49° (36° to 65°; p < 0.001). Mean pelvic obliquity corrected from 19.5° (8° to 46°) to 9.8° (0° to 20°; p < 0.001). Coronal and sagittal balance restored to normal. Complication rate was 58.3% (seven patients) with no neurological deficits,
Aims. To report the surgical outcome of patients with severe Scheuermann’s kyphosis treated using a consistent technique and perioperative management. Methods. We reviewed 88 consecutive patients with a severe Scheuermann's kyphosis who had undergone posterior spinal fusion with closing wedge osteotomies and hybrid instrumentation. There were 55 males and 33 females with a mean age of 15.9 years (12.0 to 24.7) at the time of surgery. We recorded their demographics, spinopelvic parameters, surgical correction, and perioperative data, and assessed the impact of surgical complications on outcome using the Scoliosis Research Society (SRS)-22 questionnaire. Results. The mean follow-up was 8.4 years (2 to 14.9). There were 85 patients (96.6%) with a thoracic deformity. Posterior spinal fusion with closing-wedge osteotomies and hybrid instrumentation was used in 86 patients; two patients underwent combined anterior and posterior spinal fusion. The mean kyphosis was corrected from 94.5° to 47.5° (p < 0.001). Coronal and sagittal balance returned to normal. The rate of complications was 12.5%: there were no neurological deficits,
The aim of this study was to investigate the impact of the level of upper instrumented vertebra (UIV) in frail patients undergoing surgery for adult spine deformity (ASD). Patients with adult spinal deformity who had undergone T9-to-pelvis fusion were stratified using the ASD-Modified Frailty Index into not frail, frail, and severely frail categories. ASD was defined as at least one of: scoliosis ≥ 20°, sagittal vertical axis (SVA) ≥ 5 cm, or pelvic tilt ≥ 25°. Means comparisons tests were used to assess differences between both groups. Logistic regression analyses were used to analyze associations between frailty categories, UIV, and outcomes.Aims

Only a few studies have investigated the long-term health-related quality of life (HRQoL) in patients with an idiopathic scoliosis. The aim of this study was to investigate the overall HRQoL and employment status of patients with an idiopathic scoliosis 40 years after diagnosis, to compare it with that of the normal population, and to identify possible predictors for a better long-term HRQoL. We reviewed the full medical records and radiological reports of patients referred to our hospital with a scoliosis of childhood between April 1972 and April 1982. Of 129 eligible patients with a juvenile or adolescent idiopathic scoliosis, 91 took part in the study (71%). They were evaluated with full-spine radiographs and HRQoL questionnaires and compared with normative data. We compared the HRQoL between observation (n = 27), bracing (n = 46), and surgical treatment (n = 18), and between thoracic and thoracolumbar/lumbar (TL/L) curves.Aims

Postoperative complication rates remain relatively high after adult spinal deformity (ASD) surgery. The extent to which modifiable patient-related factors influence complication rates in patients with ASD has not been effectively evaluated. The aim of this retrospective cohort study was to evaluate the association between modifiable patient-related factors and complications after corrective surgery for ASD. ASD patients with two-year data were included. Complications were categorized as follows: any complication, major, medical, surgical, major mechanical, major radiological, and reoperation. Modifiable risk factors included smoking, obesity, osteoporosis, alcohol use, depression, psychiatric diagnosis, and hypertension. Patients were stratified by the degree of baseline deformity (low degree of deformity (LowDef)/high degree of deformity (HighDef): below or above 20°) and age (Older/Younger: above or below 65 years). Complication rates were compared for modifiable risk factors in each age/deformity group, using multivariable logistic regression analysis to adjust for confounders.Aims

Lumbar disc prolapse is a frequent indication for surgery. The few available long-term follow-up studies focus mainly on repeated surgery for recurrent disease. The aim of this study was to analyze all reasons for additional surgery for patients operated on for a primary lumbar disc prolapse. We retrieved data from the Swedish spine register about 3,291 patients who underwent primary surgery for a lumbar disc prolapse between January 2007 and December 2008. These patients were followed until December 2020 to record all additional lumbar spine operations and the reason for them.Aims

Aims. The aims of this study were to evaluate the clinical and radiological
outcomes of instrumented posterolateral fusion (PLF) performed in
patients with rheumatoid arthritis (RA). . Methods. A total of 40 patients with RA and 134 patients without RA underwent
instrumented PLF for spinal stenosis between January 2003 and December
2011. The two groups were matched for age, gender, bone mineral
density, the history of smoking and diabetes, and number of fusion
segments. . The clinical outcomes measures included the visual analogue scale
(VAS) and the Korean Oswestry Disability Index (KODI), scored before
surgery, one year and two years after surgery. Radiological outcomes
were evaluated for problems of fixation, nonunion, and adjacent
segment disease (ASD). The mean follow-up was 36.4 months in the RA
group and 39.1 months in the non-RA group. Results. Both groups had significant improvement in symptoms one year
after surgery, while the RA group showed some deterioration of outcome
scores owing to complications during the second year after surgery.
Complications occurred at a higher rate in the group with RA (19
patients, 47.5%) than in those without RA (23 patients, 17.1%) (p
<
0.001). A total of 15 patients in the RA group (37.5%) required
revision surgery, mainly for
Between January 1990 and December 2000 we carried out 226 SB Charité III disc replacements for lumbar disc degeneration in 160 patients. They were reviewed at a mean follow-up of 79 months (31 to 161) to determine the clinical and radiological outcome. The clinical results were collected by an independent observer, who was not involved in patient selection, treatment or follow-up, using a combination of outcome measures, including the Oswestry Disability Index. Pain was recorded using a visual analogue score, and the most recent radiographs were reviewed. Survival of the device was analysed by the Kaplan-Meier method and showed a cumulative survival of 35% at 156 months when radiological failure was taken as the endpoint. The mean improvement in the Oswestry disability index scores after disc replacement was 14% (6% to 21%) and the mean improvement in the pain score was 1.6 (0.46 to 2.73), both falling below the clinically significant threshold. Removal of the implant was required in 12 patients, four because of
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

Aims. The aim of this study is to introduce and investigate the efficacy
and feasibility of a new vertebral osteotomy technique, vertebral
column decancellation (VCD), for rigid thoracolumbar kyphotic deformity
(TLKD) secondary to ankylosing spondylitis (AS). . Patients and Methods. We took 39 patients from between January 2009 and January 2013
(26 male, 13 female, mean age 37.4 years, 28 to 54) with AS and
a TLKD who underwent VCD (VCD group) and compared their outcome
with 45 patients (31 male, 14 female, mean age 34.8 years, 23 to
47) with AS and TLKD, who underwent pedicle subtraction osteotomy
(PSO group), according to the same selection criteria. The technique
of VCD was performed at single vertebral level in the thoracolumbar
region of AS patients according to classification of AS kyphotic
deformity. Pre- and post-operative chin-brow vertical angle (CBVA),
sagittal vertical axis (SVA) and sagittal Cobb angle in the thoracolumbar
region were reviewed in the VCD and PSO groups. Intra- , post-operative
and general complications were analysed in both group. Results. lf patients could lie on their backs and walk with horizontal
vision and sagittal profile, radiographic parameters improved significantly
post-operatively in both groups. No major acute complications such
as death or complete paralysis occurred in either group. In the
VCD group, five patients (12.8%) experienced complications such
as severe CSF leak (n = 4), deep wound infection (n = 1) and in
one patient a transient neurological deficit occurred. In the PSO group,
eight patients (17.8%) suffered conditions such as severe CSF leak
(n = 5), infections (n = 2) and sagittal translation at osteotomy
site (n = 1). Scoliosis Research Society outcomes instrument (SRS-22)
improved significantly in both groups. All patients achieved solid
fusion at latest follow-up and no
To describe a staged surgical technique to correct significant progressive sagittal malalignment, without the need for 3-column osteotomy, in patients with prior long thoracolumbar instrumentation for scoliosis and to evaluate the radiographic and clinical outcome from this surgical strategy. A small cohort study (n=6) of patients with significant sagittal malalignment following extensive thoracolumbar instrumented fusions for scoliotic deformity. Radiographic parameters analysed included pelvic incidence, pelvic tilt, sacral slope, lumbar lordosis, thoracic kyphosis and sagittal vertical axis. Clinical outcome measures collected included EQ-5D, ODI, SRS 22 and VAS Pain Scores. 3 patients had 2-stage anterior release and instrumented fusion followed by a posterior instrumented fusion 3 patients with a large sagittal plane deformity had a 3-stage surgical technique. All patients achieved an excellent correction of sagittal alignment, with no surgical complications and excellent health related quality of life (HRQOL) outcome measures at follow-up. There was no symptomatic non-unions or
The British Spine Registry (BSR) was introduced in May 2012 to be used as a web-based database for spinal surgeries carried out across the UK. Use of this database has been encouraged but not compulsory, which has led to a variable level of engagement in the UK. In 2019 NHS England and NHS Improvement introduced a new Best Practice Tariff (BPT) to encourage input of spinal surgical data on the BSR. The aim of our study was to assess the impact of the spinal BPT on compliance with the recording of surgical data on the BSR. A retrospective review of data was performed at a tertiary spinal centre between 2018 to 2020. Data were collated from electronic patient records, theatre operating lists, and trust-specific BSR data. Information from the BSR included operative procedures (mandatory), patient consent, email addresses, and demographic details. We also identified Healthcare Resource Groups (HRGs) which qualified for BPT.Aims

STUDY DESIGN. Retrospective review of outcome of submuscular rod placement without apical fusion for the treatment of scoliotic deformities in children with severe co morbidities (ASA IV). METHODS. 6 children with progressive scoliosis (2 severe cerebral palsy, 2 congenital cyanotic heart disease, 1 Worster Drought syndrome, 1 Leigh's disease), underwent a serial and limited exposure of the lower and then the upper end of the spine, and insertion of pedicle screws, hooks and clamps. Two submuscularly rods were connected and distracted. Mean age was 13 years old, the mean preoperatively Cobb angle was 87° and the mean postoperatively Cobb angle was 62°. The mean operation time was 120 min and the peri-operative blood loss was 410 ml. Mean follow up is 15 months. RESULTS. There were no adverse peri-operative events. We anticipated late
Introduction/Aim. Numerous lumbo-pelvic reconstruction methods based on posterior construct and anterior cages have been proposed for cases involving total sacrectomy and lumbar vertebrectomy. These constructs create long lever arms and generate high cantilever forces across the lumbo-sacral junction resulting in
Clinical and radiological indicators of outcome in the use of X-Stops were sought by evaluating patient-centred outcomes alongside radiographic scrutiny of changes around implants with correlation to outcome. Prospectively collated outcome scores were correlated to outcome, with retrospective analysis of pre-operative MRI scans and 117 post-operative radiographs.

Aim. To evaluate the level of health resource utilisation by patients after lumbar total disc replacement (TDR) for mechanical low back pain. Method. At our centre, 35 patients underwent TDR and were followed prospectively from surgery. All surgery was performed by the senior author. Patients were followed routinely in clinic at yearly intervals. In addition, the patients and their GPs were contacted via telephone. Information gathered included ODI and VAS, satisfaction with surgery and return to work. We specifically established whether the patients continued to seek healthcare, for persistent back symptoms, from professionals (both NHS and private) including their GP, pain clinic, physiotherapist, acupuncturist, chiropractor or another spinal surgeon, and had any further interventions. Results. We have complete dataset on 30 out of 35 patients and are the subject of this study. There were 13 men, with a mean age of 37.7 years (range 28-45 years), and 17 women with a mean age of 49.8 years (range 27-62 years). Surgery was single level in 26 and two levels in 6 cases. Patients were satisfied with the outcome of surgery in 21 cases (70%), not satisfied in 7. Two cases had
Introduction. Spinopelvic parameters describe the orientation, shape, and morphology of the spine and pelvis. In children without spinal deformity, these parameters change during the first 10 years of life; however, spinopelvic parameters need to be defined in children with significant early-onset scoliosis (EOS). The purpose of this study is to examine the effects of EOS on sagittal spinopelvic alignment. We hypothesise that sagittal spinopelvic parameters for patients with EOS will differ from age-matched children without spinal deformity. These values will act as a baseline for future studies and may predict postoperative complications such as proximal junctional kyphosis and
Magnetically controlled growing rods (MCGR) have been gaining popularity in the management of early-onset scoliosis (EOS) over the past decade. We present our experience with the first 44 MCGR consecutive cases treated at our institution. This is a retrospective review of consecutive cases of MCGR performed in our institution between 2012 and 2018. This cohort consisted of 44 children (25 females and 19 males), with a mean age of 7.9 years (3.7 to 13.6). There were 41 primary cases and three revisions from other rod systems. The majority (38 children) had dual rods. The group represents a mixed aetiology including idiopathic (20), neuromuscular (13), syndromic (9), and congenital (2). The mean follow-up was 4.1 years, with a minimum of two years. Nine children graduated to definitive fusion. We evaluated radiological parameters of deformity correction (Cobb angle), and spinal growth (T1-T12 and T1-S1 heights), as well as complications during the course of treatment.Aims

Background. Wallis implant was developed in 1986 to stiffen unstable operated degenerate lumbar segments while preserving some intervertebral mobility. The long-term results of first-generation Wallis implant from developers were promising. However, documentation pertaining to safety and efficacy of second generation Wallis implant is sparse in literature. Purpose. The objective of this study was to assess the clinical outcome of the second generation Wallis interspinous device for degenerative lumbar disc disease. Study design. Prospective consecutive single surgeon series. Methods. Patients were selected according to recommendations by developers of Wallis implant. Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) were used to assess patient outcomes.
To report the mid-term results of a modified self-growing rod (SGR) technique for the treatment of idiopathic and neuromuscular early-onset scoliosis (EOS). We carried out a retrospective analysis of 16 consecutive patients with EOS treated with an SGR construct at a single hospital between September 2008 and December 2014. General demographics and deformity variables (i.e. major Cobb angle, T1 to T12 length, T1 to S1 length, pelvic obliquity, shoulder obliquity, and C7 plumb line) were recorded preoperatively, and postoperatively at yearly follow-up. Complications and revision procedures were also recorded. Only patients with a minimum follow-up of five years after surgery were included.Aims
