Ultrasound can be used to outline the spinous processes and the laminae, and thus to measure axial rotation. Using our own technique, we measured vertebral rotation in 47 patients with idiopathic scoliosis. There was a strong linear relationship between the Cobb angle and the rotation of the apical vertebra in untreated patients, but this relationship was lost in patients who had had
The aim of this study was to assess the ability of morphological spinal parameters to predict the outcome of bracing in patients with adolescent idiopathic scoliosis (AIS) and to establish a novel supine correction index (SCI) for guiding bracing treatment. Patients with AIS to be treated by bracing were prospectively recruited between December 2016 and 2018, and were followed until brace removal. In all, 207 patients with a mean age at recruitment of 12.8 years (SD 1.2) were enrolled. Cobb angles, supine flexibility, and the rate of in-brace correction were measured and used to predict curve progression at the end of follow-up. The SCI was defined as the ratio between correction rate and flexibility. Receiver operating characteristic (ROC) curve analysis was carried out to assess the optimal thresholds for flexibility, correction rate, and SCI in predicting a higher risk of progression, defined by a change in Cobb angle of ≥ 5° or the need for surgery.Aims
Methods
This study addressed two questions: first, does surgical correction of an idiopathic scoliosis increase the volume of the rib cage, and second, is it possible to evaluate the change in lung function after corrective surgery for adolescent idiopathic scoliosis (AIS) using biplanar radiographs of the ribcage with 3D reconstruction? A total of 45 patients with a thoracic AIS which needed surgical correction and fusion were included in a prospective study. All patients underwent pulmonary function testing (PFT) and low-dose biplanar radiographs both preoperatively and one year after surgery. The following measurements were recorded: forced vital capacity (FVC), slow vital capacity (SVC), and total lung capacity (TLC). Rib cage volume (RCV), maximum rib hump, main thoracic curve Cobb angle (MCCA), medial-lateral and anteroposterior diameter, and T4-T12 kyphosis were calculated from 3D reconstructions of the biplanar radiographs.Aims
Methods
In this cross-over study, we evaluated two types of knee brace commonly used in the conservative treatment of osteoarthritis of the medial compartment. Twelve patients confirmed radiologically as having unilateral osteoarthritis of the medial compartment (Larsen grade 2 to grade 4) were studied. Treatment with a simple hinged brace was compared with that using a valgus corrective brace. Knee kinematics, ground reaction forces, pain and function were assessed during walking and the Hospital for Special Surgery scores were also determined. Significant improvements in pain, function, and loading and propulsive forces were seen with the valgus
The aim of this study was to compare the surgical and quality-of-life outcomes of children with skeletal dysplasia to those in children with idiopathic early-onset scoliosis (EOS) undergoing growth-friendly management. A retrospective review of two prospective multicentre EOS databases identified 33 children with skeletal dysplasia and EOS (major curve ≥ 30°) who were treated with growth-friendly instrumentation at younger than ten years of age, had a minimum two years of postoperative follow-up, and had undergone three or more lengthening procedures. From the same registries, 33 matched controls with idiopathic EOS were identified. A total of 20 children in both groups were treated with growing rods and 13 children were treated with vertical expandable prosthetic titanium rib (VEPTR) instrumentation.Aims
Patients and Methods
Our aim was to assess the effectiveness of a protocol involving
a standardised closed reduction for the treatment of children with
developmental dysplasia of the hip (DDH) in maintaining reduction
and to report the mid-term results. A total of 133 hips in 120 children aged less than two years
who underwent closed reduction, with a minimum follow-up of five
years or until subsequent surgery, were included in the study. The
protocol defines the criteria for an acceptable reduction and the
indications for a concomitant soft-tissue release. All children
were immobilised in a short- leg cast for three months. Arthrograms
were undertaken at the time of closed reduction and six weeks later. Follow-up
radiographs were taken at six months and one, two and five years
later and at the latest follow-up. The Tönnis grade, acetabular
index, Severin grade and signs of osteonecrosis were recorded.Aims
Methods
Randomised controlled trials (RCTs) that assessed
the efficacy of bracing for adolescent idiopathic scoliosis have suffered
from small sample sizes, low compliance and lack of willingness
to participate. The aim of this study was to assess the feasibility
of a comprehensive cohort study for evaluating both the efficacy
and the effectiveness of bracing in patients with adolescent idiopathic
scoliosis. Patients with curves at greater risk of progression were invited
to join a randomised controlled trial. Those who declined were given
the option to remain in the study and to choose whether they wished
to be braced or observed. Of 87 eligible patients (5 boys and 63
girls) identified over one year, 68 (78%) with mean age of 12.5
years (10 to 15) consented to participate, with a mean follow-up
of 168 weeks (0 to 290). Of these, 19 (28%) accepted randomisation.
Of those who declined randomisation, 18 (37%) chose a brace. Patients
who were more satisfied with their image were more likely to choose
bracing (Odds Ratio 4.1; 95% confidence interval 1.1 to 15.0; p = 0.035).
This comprehensive cohort study design facilitates the assessment
of both efficacy and effectiveness of bracing in patients with adolescent
idiopathic scoliosis, which is not feasible in a conventional randomised
controlled trial. Cite this article:
We report the use of the distal radius and ulna (DRU) classification
for the prediction of peak growth (PG) and growth cessation (GC)
in 777 patients with idiopathic scoliosis. We compare this classification
with other commonly used parameters of maturity. The following data were extracted from the patients’ records
and radiographs: chronological age, body height (BH), arm span (AS),
date of menarche, Risser sign, DRU grade and status of the phalangeal
and metacarpal physes. The mean rates of growth were recorded according
to each parameter of maturity. PG was defined as the summit of the curve
and GC as the plateau in deceleration of growth. The rates of growth
at PG and GC were used for analysis using receiver operating characteristic
(ROC) curves to determine the strength and cutoff values of the
parameters of growth.Aims
Patients and Methods
A self-control ratio, the spine-pelvis index
(SPI), was proposed for the assessment of patients with adolescent idiopathic
scoliosis (AIS) in this study. The aim was to evaluate the disproportionate
growth between the spine and pelvis in these patients using SPI.
A total of 64 female patients with thoracic AIS were randomly enrolled
between December 2010 and October 2012 (mean age 13 years, standard
deviation ( No significant difference in SPI was found in different age groups
in the control group, making the SPI an age-independent parameter
with a mean value of 2.219 (2.164 to 2.239). We also found that
the SPI was not related to maturity in the control group. This study, for the first time, used a self-control ratio to
confirm the disproportionate patterns of growth of the spine and
pelvis in patients with thoracic AIS, highlighting that the SPI
is not affected by age or maturity. Cite this article:
