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

Purpose and background. To evaluate the clinical and cost-effectiveness of a physical and psychological group intervention (BOOST programme) compared to physiotherapy assessment and advice (best practice advice [BPA]) for older adults with neurogenic claudication (NC) which is a debilitating spinal condition. Methods and results. A randomised controlled trial of 438 participants. The primary outcome was the Oswestry Disability Index (ODI) at 12 months. Data was also collected at 6 months. Other outcomes included Swiss Spinal Stenosis Questionnaire (symptoms), ODI walking item, 6-minute walk test (6MWT) and falls. The analysis was intention-to-treat. We collected the EQ5D and health and social care use to estimate cost-effectiveness. Participants were, on average, 74.9 years old (SD 6.0). There was no significant difference in ODI scores between groups at 12 months (adjusted mean difference (MD): −1.4 [95% Confidence Intervals (CI) −4.03,1.17]), but, at 6 months, ODI scores favoured the BOOST programme (adjusted MD: −3.7 [95% CI −6.27, −1.06]). Symptoms followed a similar pattern. The BOOST programme resulted in greater improvements in walking capacity (6MWT MD 21.7m [95% CI 5.96, 37.38]) and ODI walking item (MD −0.2 [95% CI −0.45, −0.01]) and reduced falls risk (odds ratio 0.6 [95% CI 0.40, 0.98]) compared to BPA at 12 months. Probability that the BOOST programme is cost-effective ranged from 67%–89% across cost-effectiveness thresholds. Conclusions. The BOOST programme improves mobility and reduces falls in older adults with NC compared to BPA at 12 months follow-up. It is good value for the NHS. Future iterations of the programme will consider ways to reduce symptoms and disability long-term. Conflicts of interest: No conflicts of interest.

Purpose. To observe the safety and efficacy of a minimally destructive decompressive technique without fusion in patients with lumbar stenosis secondary to degenerative spondylolisthesis. Methods. 30 patients with degenerative spondylolisthesis (DS) were consecutively managed by a single consultant spinal surgeon. All patients presented with neurogenic claudication secondary to DS. All patients were managed operatively with lumbar decompression utilising an approach technique of “spinous process osteotomy” (1). Briefly, this approach requires only unilateral muscle stripping with preservation of the interspinous ligament. A standard centrolateral decompression is then performed. Data consisting of VAS back and leg pain and ODI were collected pre and post-operatively. Results. The majority of patients were women (23) with a median age of 66 years. 29 patients had grade 1 slip and 1 patient grade 2. The index level was predominantly L4/5 (25 pts; 83%) and L3/4 in the remainder (5 pts; 17%). 5 patients were noted to have a coronal plane deformity as well as DS. 3 patients underwent 2 levels of decompression. Median length of stay was 2 days (range: 1 to 13 days). 2 patients suffered a dural tear during surgery (both with scoliosis). Of these, one required a second operation to repair a pseudomeningocele. All patients improved post op (Range: 3 months to 23 months; mean 8 months). ODI significantly improved post operatively (p < 0.05). One patient, however, developed a severe recurrence of symptoms at 3 months. Repeat imaging confirmed an increased slip and recurrent stenosis. This patient underwent re-decompression supplemented with instrumented fusion. Conclusion. The technique described above facilitates a safe method of decompression alone without fusion in patients with DS, even in patients with scoliosis. The procedure is safe, successful and easy to learn. Post-operative recovery is rapid with a short hospital stay. In spite of preserving the interspinous ligament, 1/30 patients (3 %) progressed to a greater sagittal slip requiring fusion

Patients with neurogenic claudication from lumbar canal stenosis non-responsive to non-surgical treatment are usually managed with spinal decompression with or without fusion. Flexion at stenotic segments relieves symptoms by increasing canal cross-sectional area, intervertebral foraminal height. Interspinous spacers work by causing flexion at the treated segement. We used COFLEX¯ [Paradigm Spine] a titanium interspinous spacer along with interlaminar decompression where indicated. To compare the clinical and radiological results of patients undergoing interlaminar decompression with or without use of COFLEX¯. Pre and post-operative assessment and comparison of clinical outcomes of Oswestry disability index(ODI), Visual analog Scale(VAS), Short Form-36(SF-36) and radiological outcomes of disc heights of operated and adjacent levels, intervertebral foraminal heights, sagittal angles of the operated segment. All consecutive patients undergoing spinal decompression at one or more levels from Jan to Dec 2008 were included. Patients with clinically symptomatic back pain for a duration longer than claudication pain were offered interspinous spacer at L4/5 level or above. In first group(n-20), patients were treated with inter-laminar decompression and COFLEX¯ with a standard posterior approach. In second group(n-25) inter-laminar decompression for the involved segment was performed. All patients are on follow-up. Clinical and radiological outcomes were compared at 6 months and 1 year. Statistically significant(p<0.001) improvements in ODI, VAS(back), VAS(leg) and SF-36 in patients in whom COFLEX¯ was used. Radiological parameters also showed significant improvements(p<0.05). Use of COFLEX¯ spacer is justified in patients with symptomatic disc degeneration with neurogenic claudication when treated operatively

Aims

Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient’s prognosis. Categories of CES attempt to group patients for management and prognostication purposes. We aimed in this study to assess the inter-rater reliability of dividing patients with CES into categories to assess whether they can be reliably applied in clinical practice and in research.

Aims

Traumatic central cord syndrome (CCS) typically follows a hyperextension injury and results in motor impairment affecting the upper limbs more than the lower, with occasional sensory impairment and urinary retention. Current evidence on mortality and long-term outcomes is limited. The primary aim of this study was to assess the five-year mortality of CCS, and to determine any difference in mortality between management groups or age.

This review provides a concise outline of the advances made in the care of patients and to the quality of life after a traumatic spinal cord injury (SCI) over the last century. Despite these improvements reversal of the neurological injury is not yet possible. Instead, current treatment is limited to providing symptomatic relief, avoiding secondary insults and preventing additional sequelae. However, with an ever-advancing technology and deeper understanding of the damaged spinal cord, this appears increasingly conceivable. A brief synopsis of the most prominent challenges facing both clinicians and research scientists in developing functional treatments for a progressively complex injury are presented. Moreover, the multiple mechanisms by which damage propagates many months after the original injury requires a multifaceted approach to ameliorate the human spinal cord. We discuss potential methods to protect the spinal cord from damage, and to manipulate the inherent inhibition of the spinal cord to regeneration and repair. Although acute and chronic SCI share common final pathways resulting in cell death and neurological deficits, the underlying putative mechanisms of chronic SCI and the treatments are not covered in this review.

Aims

Lumbar spinal stenosis (LSS) is a common skeletal system disease that has been partly attributed to genetic variation. However, the correlation between genetic variation and pathological changes in LSS is insufficient, and it is difficult to provide a reference for the early diagnosis and treatment of the disease.

Aims

To identify the incidence and risk factors for five-year same-site recurrent disc herniation (sRDH) after primary single-level lumbar discectomy. Secondary outcome was the incidence and risk factors for five-year sRDH reoperation.

Aims

Cauda equina syndrome (CES) can be associated with chronic severe lower back pain and long-term autonomic dysfunction. This study assesses the recently defined core outcome set for CES in a cohort of patients using validated questionnaires.

Aims

To report the outcome of spinal deformity correction through anterior spinal fusion in wheelchair-bound patients with myelomeningocele.

Aims

The aim of this study was to compare the outcomes of surgery using growing rods in patients with severe versus moderate early-onset scoliosis (EOS).

Aims

The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events.

Aims

The aim of this study was to determine the influence of developmental spinal stenosis (DSS) on the risk of re-operation at an adjacent level.

Objectives

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.

We validated the North American Spine Society (NASS) outcome-assessment instrument for the lumbar spine in a computerised touch-screen format and assessed patients’ acceptance, taking into account previous computer experience, age and gender.

Fifty consecutive patients with symptomatic and radiologically-proven degenerative disease of the lumbar spine completed both the hard copy (paper) and the computerised versions of the NASS questionnaire. Statistical analysis showed high agreement between the paper and the touch-screen computer format for both subscales (intraclass correlation coefficient 0.94, 95% confidence interval (0.90 to 0.97)) independent of computer experience, age and gender. In total, 55% of patients stated that the computer format was easier to use and 66% preferred it to the paper version (p < 0.0001 among subjects expressing a preference). Our data indicate that the touch-screen format is comparable to the paper form. It may improve follow-up in clinical practice and research by meeting patients’ preferences and minimising administrative work.

Objectives

Pedicle-lengthening osteotomy is a novel surgery for lumbar spinal stenosis (LSS), which achieves substantial enlargement of the spinal canal by expansion of the bilateral pedicle osteotomy sites. Few studies have evaluated the impact of this new surgery on spinal canal volume (SCV) and neural foramen dimension (NFD) in three different types of LSS patients.

Aims

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.

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).

Pain catastrophising is an adverse coping mechanism, involving an exaggerated response to anticipated or actual pain.

The purpose of this study was to investigate the influence of pain ‘catastrophising’, as measured using the pain catastrophising scale (PCS), on treatment outcomes after surgery for lumbar spinal stenosis (LSS).

A total of 138 patients (47 men and 91 women, mean age 65.9; 45 to 78) were assigned to low (PCS score < 25, n = 68) and high (PCS score ≥ 25, n = 70) PCS groups. The primary outcome measure was the Oswestry Disability Index (ODI) 12 months after surgery. Secondary outcome measures included the ODI and visual analogue scale (VAS) for back and leg pain, which were recorded at each assessment conducted during the 12-month follow-up period

The overall changes in the ODI and VAS for back and leg pain over a 12-month period were significantly different between the groups (ODI, p < 0.001; VAS for back pain, p < 0.001; VAS for leg pain, p = 0.040). The ODI and VAS for back and leg pain significantly decreased over time after surgery in both groups (p < 0.001 for all three variables). The patterns of change in the ODI and VAS for back pain during the follow-up period significantly differed between the two groups, suggesting that the PCS group is a potential treatment moderator. However, there was no difference in the ODI and VAS for back and leg pain between the low and high PCS groups 12 months after surgery.

In terms of minimum clinically important differences in ODI scores (12.8), 22 patients (40.7%) had an unsatisfactory surgical outcome in the low PCS group and 16 (32.6%) in the high PCS group. There was no statistically significant difference between the two groups (p = 0.539).

Pre-operative catastrophising did not always result in a poor outcome 12 months after surgery, which indicates that this could moderate the efficacy of surgery for LSS.
