The primary aim of this study was to evaluate the performance
and safety of magnetically controlled growth rods in the treatment
of early onset scoliosis. Secondary aims were to evaluate the clinical
outcome, the rate of further surgery, the rate of complications,
and the durability of correction. We undertook an observational prospective cohort study of children
with early onset scoliosis, who were recruited over a one-year period
and followed up for a minimum of two years. Magnetically controlled
rods were introduced in a standardized manner with distractions
performed three-monthly thereafter. Adverse events which were both related
and unrelated to the device were recorded. Ten children, for whom
relevant key data points (such as demographic information, growth
parameters, Cobb angles, and functional outcomes) were available,
were recruited and followed up over the period of the study. There
were five boys and five girls. Their mean age was 6.2 years (2.5
to 10).Aims
Patients and Methods
Magnetically controlled growing rods (MCGRs) allow non-invasive
correction of the spinal deformity in the treatment of early-onset
scoliosis. Conventional growing rod systems (CGRS) need repeated
surgical distractions: these are associated with the effect of the
‘law of diminishing returns’. The primary aim of this study was to quantify this effect in
MCGRs over sequential distractions. A total of 35 patients with a maximum follow-up of 57 months
were included in the study. There were 17 boys and 18 girls with
a mean age of 7.4 years (2 to 14). True Distraction (TD) was determined
by measuring the expansion gap on fluoroscopy. This was compared
with Intended Distraction (ID) and expressed as the ‘T/I’ ratio.
The T/I ratio and the Cobb angle were calculated at several time
points during follow-up.Aims
Patients and Methods
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 assessed the frequency and causes of neurological
deterioration in 59 patients with spinal cord injury on whom reports
were prepared for clinical negligence litigation. In those who deteriorated
neurologically we assessed the causes of the change in neurology
and whether that neurological deterioration was potentially preventable.
In all 27 patients (46%) changed neurologically, 20 patients (74%
of those who deteriorated) had no primary neurological deficit.
Of those who deteriorated, 13 (48%) became Frankel A. Neurological
deterioration occurred in 23 of 38 patients (61%) with unstable
fractures and/or dislocations; all 23 patients probably deteriorated
either because of failures to immobilise the spine or because of
inappropriate removal of spinal immobilisation. Of the 27 patients who
altered neurologically, neurological deterioration was, probably,
avoidable in 25 (excess movement in 23 patients with unstable injuries,
failure to evacuate an epidural haematoma in one patient and over-distraction following
manipulation of the cervical spine in one patient). If existing
guidelines and standards for the management of actual or potential
spinal cord injury had been followed, neurological deterioration
would have been prevented in 25 of the 27 patients (93%) who experienced
a deterioration in their neurological status. Cite this article:
We have assessed whether an epidural steroid injection is effective in the treatment of symptoms due to compression of a nerve root in the lumbar spine by carrying out a prospective, randomised, controlled trial in which patients received either an epidural steroid injection or an intramuscular injection of local anaesthetic and steroid. We assessed a total of 93 patients according to the Oxford pain chart and the Oswestry disability index and followed up for a minimum of two years. All the patients had been categorised as potential candidates for surgery. There was a significant reduction in pain early on in those having an epidural steroid injection but no difference in the long term between the two groups. The rate of subsequent operation in the groups was similar.
Instability may present at a different level after successful stabilisation of an unstable segment in apparently isolated injuries of the cervical spine. It can give rise to progressive deformity or symptoms which require further treatment. We performed one or more operations for unstable cervical spinal injuries on 121 patients over a period of 90 months. Of these, five were identified as having instability due to an initially unrecognised fracture-subluxation at a different level. We present the details of these five patients and discuss the problems associated with their diagnosis and treatment.
