Aims. The aim of this study was to assess whether supine flexibility predicts the likelihood of curve progression in patients with adolescent idiopathic scoliosis (AIS) undergoing brace treatment. Methods. This was a retrospective analysis of patients with AIS prescribed with an underarm brace between September 2008 to April 2013 and followed up until 18 years of age or required surgery. Patients with structural proximal curves that preclude underarm bracing, those who were lost to follow-up, and those who had poor compliance to bracing (<16 hours a day) were excluded. The major curve Cobb angle, curve type, and location were measured on the pre-brace standing posteroanterior (PA) radiograph, supine whole spine radiograph, initial in-brace standing PA radiograph, and the post-brace weaning standing PA radiograph. Validation of the previous in-brace Cobb angle regression model was performed. The outcome of curve progression post-bracing was tested using a logistic regression model. The supine flexibility cut-off for curve progression was analyzed with receiver operating characteristic curve. Results. A total of 586 patients with mean age of 12.6 years (SD 1.2) remained for analysis after exclusion. The baseline Cobb angle was similar for thoracic major curves (31.6° (SD 3.8°)) and
Aims. This study compared the long-term results following Salter osteotomy
and Pemberton acetabuloplasty in children with developmental dysplasia
of the hip (DDH). We assessed if there was a greater increase in
pelvic height following the Salter osteotomy, and if this had a
continued effect on pelvic tilt,
To examine the long-term outcome of arthrodesis of the hip undertaken in a paediatric population in treating painful arthritis of the hip. In our patient population, most of whom live rurally in hilly terrain and have limited healthcare access and resources, hip arthrodesis has been an important surgical option for the monoarticular painful hip in a child. A follow-up investigation was undertaken on a cohort of 28 children previously reported at a mean of 4.8 years. The present study looked at 26 patients who had an arthrodesis of the hip as a child at a mean follow-up of 20 years (15 to 29).Aims
Methods
The health-related quality of life (HRQoL) of paediatric patients with orthopaedic conditions and spinal deformity is important, but existing generic tools have their shortcomings. We aim to evaluate the use of Paediatric Quality of Life Inventory (PedsQL) 4.0 generic core scales in the paediatric population with specific comparisons between those with spinal and limb pathologies, and to explore the feasibility of using PedsQL for studying scoliosis patients’ HRQoL. Paediatric patients attending a speciality outpatient clinic were recruited through consecutive sampling. Two groups of patients were included: idiopathic scoliosis, and paediatric orthopaedic upper and lower limb condition without scoliosis. Patients were asked to complete PedsQL 4.0 generic core scales, Youth version of 5-level EuroQol-5-dimension questionnaire, and Refined Scoliosis Research Society 22-item (SRS-22r) questionnaire. Statistical analyses included scores comparison between scoliosis and limb pathology patients using independent-samples Aims
Methods
This multicentre, retrospective study aimed to improve our knowledge
of primary pyogenic spinal infections in children by analyzing a
large consecutive case series. The medical records of children with such an infection, treated
at four tertiary institutions between 2004 and 2014, were analyzed
retrospectively. Epidemiological, clinical, paraclinical, radiological,
and microbiological data were evaluated. There were 103 children,
of whom 79 (76.7%) were aged between six months and four years.Aims
Patients and Methods
Discitis is uncommon in children and presents in different ways at different ages. It is most difficult to diagnose in the uncommunicative toddler of one to three years of age. We present 11 consecutive cases. The non-specific clinical features included refusal to walk (63%), back pain (27%), inability to flex the lower back (50%) and a loss of
We report five children who presented at the mean age of 1.5 years (1.1 to 1.9) with a progressive thoracolumbar kyphosis associated with segmental instability and subluxation of the spine at the level above an anteriorly-wedged hypoplastic vertebra at L1 or L2. The spinal deformity appeared to be developmental and not congenital in origin. The anterior wedging of the vertebra may have been secondary to localised segmental instability and subsequent kyphotic deformity. We suggest the term ‘infantile developmental thoracolumbar kyphosis with segmental subluxation of the spine’ to differentiate this type of deformity from congenital displacement of the spine in which the congenital vertebral anomaly does not resolve. Infantile developmental kyphosis with segmental subluxation of the spine, if progressive, may carry the risk of neurological compromise. In all of our patients the kyphotic deformity progressed over a period of three months and all were treated by localised posterior spinal fusion. At a mean follow-up of 6.6 years (5.0 to 9.0), gradual correction of the kyphosis was seen on serial radiographs as well as reconstitution of the hypoplastic wedged vertebra to normality. Exploration of the arthrodesis was necessary at nine months in one patient who developed a pseudarthrosis.
We undertook a retrospective analysis of 306
procedures on 233 patients, with a mean age of 12 years (1 to 21),
in order to evaluate the use of somatosensory evoked potential (SSEP)
monitoring for the early detection of nerve compromise during external
fixation procedures for limb lengthening and correction of deformity.
Significant SSEP changes were identified during 58 procedures (19%).
In 32 instances (10.5%) the changes were transient, and resolved
once the surgical cause had been removed. The remaining 26 (8.5%)
were analysed in two groups, depending on whether or not corrective
action had been performed in response to critical changes in the
SSEP recordings. In 16 cases in which no corrective action was taken,
13 (81.2%, 4.2% overall) developed a post-operative neurological
deficit, six of which were permanent and seven temporary, persisting
for five to 18 months. In the ten procedures in which corrective
action was taken, four patients (40%, 1.3% overall) had a temporary
(one to eight months) post-operative neuropathy and six had no deficit. After appropriate intervention in response to SSEP changes, the
incidence and severity of neurological deficits were significantly
reduced, with no cases of permanent neuropathy. SSEP monitoring
showed 100% sensitivity and 91% specificity for the detection of
nerve injury during external fixation. It is an excellent diagnostic
technique for identifying nerve lesions when they are still highly
reversible.
Permanent growth arrest of the longer bone is
an option in the treatment of minor leg-length discrepancies. The
use of a tension band plating technique to produce a temporary epiphysiodesis
is appealing as it avoids the need for accurate timing of the procedure
in relation to remaining growth. We performed an animal study to
establish if control of growth in a long bone is possible with tension
band plating. Animals (pigs) were randomised to temporary epiphysiodesis
on either the right or left tibia. Implants were removed after ten
weeks. Both tibiae were examined using MRI at baseline, and after
ten and 15 weeks. The median interphyseal distance was significantly shorter
on the treated tibiae after both ten weeks (p = 0.04) and 15 weeks
(p = 0.04). On T1-weighted images the metaphyseal water
content was significantly reduced after ten weeks on the treated
side (p = 0.04) but returned to values comparable with the untreated
side at 15 weeks (p = 0.14). Return of growth was observed in all
animals after removal of implants. Temporary epiphysiodesis can be obtained using tension band plating.
The technique is not yet in common clinical practice but might avoid
the need for the accurate timing of epiphysiodesis. Cite this article:
We describe a patient with cerebral palsy, of normal intelligence, who could not walk but who by the age of 16 had been successfully managed with a staged bilateral total hip arthroplasty using a constrained liner.
We retrospectively reviewed the records of 16 children treated for spondylodiscitis at our hospital between 2000 and 2007. The mean follow-up was 24 months (12 to 38). There was a mean delay in diagnosis in hospital of 25 days in the ten children aged less than 24 months. At presentation only five of the 16 children presented with localising signs and symptoms. Common presenting symptoms were a refusal to walk or sit in nine children, unexplained fever in six, irritability in five, and limping in four. Plain radiography showed changes in only seven children. The ESR was the most useful investigation when following the clinical course of the disease. Positive blood cultures were obtained in seven children with The early use of MRI in the investigation of children with an atypical picture may avoid unnecessary delay in starting treatment and possibly prevent long-term problems. All except one of our children had made a complete clinical recovery at final follow-up. However, all six children in the >
24-month age group showed radiological evidence of degenerative changes which might cause problems in the future.
A delay in the diagnosis of paediatric acute
and subacute haematogenous osteomyelitis can lead to potentially devastating
morbidity. There are no definitive guidelines for diagnosis, and
recommendations in the literature are generally based on expert
opinions, case series and cohort studies. All articles in the English literature on paediatric osteomyelitis
were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the
Cochrane Library and reference lists. A total of 1854 papers were
identified, 132 of which were examined in detail. All aspects of
osteomyelitis were investigated in order to formulate recommendations. On admission 40% of children are afebrile. The tibia and femur
are the most commonly affected long bones. Clinical examination,
blood and radiological tests are only reliable for diagnosis in
combination. Most studies were retrospective and there is a need for large,
multicentre, randomised, controlled trials to define protocols for
diagnosis and treatment. Meanwhile, evidence-based algorithms are
suggested for accurate and early diagnosis and effective treatment.
Between July 2000 and April 2004, 19 patients with bilateral spastic cerebral palsy who required an assistive device to walk had combined lengthening-transfer of the medial hamstrings as part of multilevel surgery. A standardised physical examination, measurement of the Functional Mobility Scale score and video or instrumented gait analysis were performed pre- and post-operatively. Static parameters (popliteal angle, flexion deformity of the knee) and sagittal knee kinematic parameters (knee flexion at initial contact, minimum knee flexion during stance, mean knee flexion during stance) were recorded. The mean length of follow-up was 25 months (14 to 45). Statistically significant improvements in static and dynamic outcome parameters were found, corresponding to improvements in gait and functional mobility as determined by the Functional Mobility Scale. Mild hyperextension of the knee during gait developed in two patients and was controlled by adjustment of their ankle-foot orthosis. Residual flexion deformity >
10° occurred in both knees of one patient and was treated by anterior distal femoral physeal stapling. Two children also showed an improvement of one level in the Gross Motor Function Classification System.
