The aim of the study was to determine if there was a direct correlation between the pain and disability experienced by patients and size of their disc prolapse, measured by the disc’s cross-sectional area on T2 axial MRI scans. Patients were asked to prospectively complete visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores on the day of their MRI scan. All patients with primary disc herniation were included. Exclusion criteria included recurrent disc herniation, cauda equina syndrome, or any other associated spinal pathology. T2 weighted MRI scans were reviewed on picture archiving and communications software. The T2 axial image showing the disc protrusion with the largest cross sectional area was used for measurements. The area of the disc and canal were measured at this level. The size of the disc was measured as a percentage of the cross-sectional area of the spinal canal on the chosen image. The VAS leg pain and ODI scores were each correlated with the size of the disc using the Pearson correlation coefficient (PCC). Intraobserver reliability for MRI measurement was assessed using the interclass correlation coefficient (ICC). We assessed if the position of the disc prolapse (central, lateral recess, or foraminal) altered the symptoms described by the patient. The VAS and ODI scores from central and lateral recess disc prolapses were compared.Aims
Methods
The purpose of this retrospective study was to investigate the
clinical relevance of increased facet joint distraction as a result
of anterior cervical decompression and fusion (ACDF) for trauma. A total of 155 patients (130 men, 25 women. Mean age 42.7 years;
16 to 87) who had undergone ACDF between 1 January 2001 and 1 January
2016 were included in the study. Outcome measures included the Neck
Disability Index (NDI) and visual analogue scale (VAS) for pain.
Lateral cervical spine radiographs taken in the immediate postoperative
period were reviewed to compare the interfacet distance of the operated
segment with those of the facet joints above and below.Aims
Patients and Methods
We sought to determine whether specific characteristics
of vertebral fractures in elderly men are associated with low bone
mineral density (BMD) and osteoporosis. Mister osteoporosis Sweden is a population based cohort study
involving 3014 men aged 69 to 81 years. Of these, 1427 had readable
lateral radiographs of the thoracic and lumbar spine. Total body
(TB) BMD (g/cm²) and total right hip (TH) BMD were measured by dual
energy x-ray absorptiometry. The proportion of men with osteoporosis
was calculated from TH BMD. There were 215 men (15.1%) with a vertebral
fracture. Those with a fracture had lower TB BMD than those without
(p <
0.001). Among men with a fracture, TB BMD was lower in those
with more than three fractures (p = 0.02), those with biconcave
fractures (p = 0.02) and those with vertebral body compression of
>
42% (worst quartile) (p = 0.03). The mean odds ratio (OR) for
having osteoporosis when having any type of vertebral fracture was
6.1 (95% confidence interval (CI) 3.9 to 9.5) compared with those
without a fracture. A combination of more than three fractures and
compression in the worst quartile had a mean OR of 114.2 (95% CI
6.7 to 1938.3) of having osteoporosis compared with those without
a fracture. We recommend BMD studies to be undertaken in these subcohorts
of elderly men with a vertebral fracture. Cite this article: 2015;97-B:1106–10.
We report the incidence of and risk factors for
complications after scoliosis surgery in patients with Duchenne muscular
dystrophy (DMD) and compare them with those of other neuromuscular
conditions. We identified 110 (64 males, 46 females) consecutive patients
with a neuromuscular disorder who underwent correction of the scoliosis
at a mean age of 14 years (7 to 19) and had a minimum two-year follow-up.
We recorded demographic and peri-operative data, including complications
and re-operations. There were 60 patients with cerebral palsy (54.5%) and 26 with
DMD (23.6%). The overall complication rate was 22% (24 patients),
the most common of which were deep wound infection (9, 8.1%), gastrointestinal
complications (5, 4.5%) and hepatotoxicity (4, 3.6%). The complication
rate was higher in patients with DMD (10/26, 38.5%) than in those
with other neuromuscular conditions (14/84, 16.7% (p = 0.019). All
hepatotoxicity occurred in patients with DMD (p = 0.003), who also
had an increased rate of deep wound infection (19% In our series, correction of a neuromuscular scoliosis had an
acceptable rate of complications: patients with DMD had an increased
overall rate compared with those with other neuromuscular conditions.
These included deep wound infection and hepatotoxicity. Hepatotoxicity
was unique to DMD patients, and we recommend peri-operative vigilance
after correction of a scoliosis in this group. Cite this article:
