Aims. To address the natural history of severe post-tuberculous (TB)
kyphosis, with focus upon the long-term neurological outcome, occurrence
of restrictive lung disease, and the effect on life expectancy. . Patients and Methods. This is a retrospective clinical review of prospectively collected
imaging data based at a single institute. A total of 24 patients
of Southern Chinese origin who presented with spinal TB with a mean
of 113° of kyphosis (65° to 159°) who fulfilled inclusion criteria
were reviewed. Plain radiographs were used to assess the degree
of spinal deformity. Myelography, CT and MRI were used when available
to assess the integrity of the spinal cord and canal. Patient demographics,
age of onset of spinal TB and interventions, types of surgical procedure,
intra- and post-operative complications, and neurological status
were assessed. . Results. All except one of the 24 patients were treated with anti-TB chemotherapy
when they were first diagnosed with spinal TB. They subsequently
received surgery either for neurological deterioration, or deformity
correction in later life. The mean follow-up was 34 years (11 to
59) since these surgical interventions. Some 16 patients (66.7%) suffered
from late neurological deterioration at a mean of 26 years (8 to
49) after the initial drug treatment. The causes of neurological
deterioration were healed disease in nine patients (56.2%),
re-activation in six patients (37.5%) and adjacent level spinal
stenosis in one patient (6.3%). The result of surgery was worse
in healed disease. Eight patients without neurological deterioration
received surgery to correct the kyphosis. The mean correction ranged
from 97° to 72°. Three patients who were clinically quiescent with
no neurological deterioration were found to have active TB of the
spine. Solid fusion was achieved in all cases and no patient suffered
from neurological deterioration after 42 years of follow-up. On
final follow-up, six patients were noted to have deceased (age range:
47 years to 75 years). Conclusion. Our study presents one of the longest assessments of spinal TB
with severe kyphosis. Severe post-TB kyphosis may lead to significant
health problems many years following the initial drug treatment.
Early surgical correction of the kyphosis, solid fusion and regular
surveillance may avoid late complications. Paraplegia, restrictive
lung disease and early onset kyphosis might relate to
We undertook a prospective non-randomised radiological study
to evaluate the preliminary results of using magnetically-controlled
growing rods (MAGEC System, Ellipse technology) to treat children
with early-onset scoliosis. Between January 2011 and January 2015, 19 children were treated
with magnetically-controlled growing rods (MCGRs) and underwent
distraction at three-monthly intervals. The mean age of our cohort
was 9.1 years (4 to 14) and the mean follow-up 22.4 months (5.1
to 35.2). Of the 19 children, eight underwent conversion from traditional growing
rods. Whole spine radiographs were carried out pre- and post-operatively:
image intensification was used during each lengthening in the outpatient
department. The measurements evaluated were Cobb angle, thoracic kyphosis,
proximal junctional kyphosis and spinal growth from T1 to S1.Aims
Patients and Methods
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:
We reviewed 31 consecutive patients with Friedreich’s
ataxia and scoliosis. There were 24 males and seven females with
a mean age at presentation of 15.5 years (8.6 to 30.8) and a mean
curve of 51° (13° to 140°). A total of 12 patients had thoracic
curvatures, 11 had thoracolumbar and eight had double thoracic/lumbar.
Two patients had long thoracolumbar collapsing scoliosis with pelvic
obliquity and four had hyperkyphosis. Left-sided thoracic curves in
nine patients (45%) and increased thoracic kyphosis differentiated
these deformities from adolescent idiopathic scoliosis. There were
17 patients who underwent a posterior instrumented spinal fusion
at mean age of 13.35 years, which achieved and maintained good correction
of the deformity. Post-operative complications included one death due
to cardiorespiratory failure, one revision to address nonunion and
four patients with proximal junctional kyphosis who did not need
extension of the fusion. There were no neurological complications
and no wound infections. The rate of progression of the scoliosis
in children kept under simple observation and those treated with bracing
was less for lumbar curves during bracing and similar for thoracic
curves. The scoliosis progressed in seven of nine children initially
treated with a brace who later required surgery. Two patients presented
after skeletal maturity with balanced curves not requiring correction.
Three patients with severe deformities who would benefit from corrective
surgery had significant cardiac co-morbidities.
