The Ponseti method is the benchmark treatment for the correction of clubfoot. The primary rate of correction is very high, but outcome further down the treatment pathway is less predictable. Several methods of assessing severity at presentation have been reported. Classification later in the course of treatment is more challenging. This systematic review considers the outcome of the Ponseti method in terms of relapse and determines how clubfoot is assessed at presentation, correction, and relapse. A prospectively registered systematic review was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies that reported idiopathic clubfoot treated by the Ponseti method between 1 January 2012 and 31 May 2017 were included. The data extracted included demographics, Ponseti methodology, assessment methods, and rates of relapse and surgery.Aims

The aim of this study was to utilize a national paediatric inpatient database to determine whether obesity influences the operative management and inpatient outcomes of paediatric limb fractures. The Kids’ Inpatient Database (KID) was used to evaluate children between birth and 17 years of age, from 1997 and 2012, who had undergone open and closed treatment of humeral, radial and ulna, femoral, tibial, and ankle fractures. Demographics, hospital charges, lengths of stay (LOS), and complications were analyzed.Aims

The aim of this study was to establish the incidence of developmental dysplasia of the hip (DDH) diagnosed after one-year of age in England, stratified by age, gender, year, and region of diagnosis. A descriptive observational study was performed by linking primary and secondary care information from two independent national databases of routinely collected data: the United Kingdom Clinical Practice Research Datalink and Hospital Episode Statistics. The study examined all children from 1 January 1990 to 1 January 2016 who had a new first diagnostic code for DDH aged between one and eight years old.Aims

The aims of this study were to evaluate the abductor function in moderate and severe slipped capital femoral epiphysis (SCFE), comparing the results of a corrective osteotomy at the base of the femoral neck and osteoplasty with 1) A total of 24 patients (mean age 14.9 years (Aims
Patients and Methods
The purpose of this study was to analyze the incidence of the different ultrasound phenotypes of developmental dysplasia of the hip (DDH), and to determine their subsequent course. A consecutive series of 28 092 neonates was screened and classified according to the Graf method as part of a nationwide surveillance programme, and then followed prospectively. Abnormal hips were followed until they became normal (Graf type I). Type IIb hips and higher grades were treated by abduction in a Tübinger orthosis until normal. Dislocated hips underwent closed or open reduction.Aims

The significance of the ‘clicky hip’ in neonatal and infant examination
remains controversial with recent conflicting papers reigniting
the debate. We aimed to quantify rates of developmental dysplasia
of the hip (DDH) in babies referred with ‘clicky hips’ to our dedicated
DDH clinic. A three-year prospective cohort study was undertaken between
2014 and 2016 assessing the diagnosis and treatment outcomes of
all children referred specifically with ‘clicky hips’ as the primary
reason for referral to our dedicated DDH clinic. Depending on their
age, they were all imaged with either ultrasound scan or radiographs.Aims
Patients and Methods
Guided growth using eight-plates is commonly used for correction
of angular limb deformities in growing children. The principle is
of tethering at the physeal periphery while enabling growth in the
rest of the physis. The method is also applied for epiphysiodesis
to correct limb-length discrepancy (LLD). Concerns have been raised
regarding the potential of this method to create an epiphyseal deformity.
However, this has not been investigated. The purpose of this study
was to detect and quantify the occurrence of deformities in the
proximal tibial epiphysis following treatment with eight-plates. A retrospective study was performed including 42 children at
a mean age of 10.8 years (3.7 to 15.7) undergoing eight-plate insertion
in the proximal tibia for correction of coronal plane deformities
or LLD between 2007 and 2015. A total of 64 plates were inserted;
48 plates (34 patients) were inserted to correct angular deformities
and 16 plates (8 patients) for LLD. Medical records, Picture Archive
and Communication System images, and conventional radiographs were
reviewed. Measurements included interscrew angle, lateral and medial
plateau slope angles measured between the plateau surface and the
line between the ends of the physis, and tibial plateau roof angle defined
as 180° minus the sum of both plateau angles. Measurements were
compared between radiographs performed adjacent to surgery and those
at latest follow-up, and between operated and non-operated plateaus. Statistical
analysis was performed using BMDP Statistical Software.Aims

Using 90% of final height as a benchmark, we sought to develop
a quick, quantitative and reproducible method of estimating skeletal
maturity based on topographical changes in the distal femoral physis. Serial radiographs of the distal femoral physis three years prior
to, during, and two years following the chronological age associated
with 90% of final height were analyzed in 81 healthy children. The
distance from the tip of the central peak of the distal femoral
physis to a line drawn across the physis was normalized to the physeal width.Aims

Delayed diagnosis is a well-known complication of a Monteggia
fracture-dislocation. If left untreated, the dislocated radial head
later becomes symptomatic. The purposes of this study were firstly,
to evaluate the clinical and radiological results of open reduction
of the radial head and secondly, to identify the factors that may
affect the outcome of this procedure. This retrospective study evaluated 30 children with a chronic
Monteggia lesion. There were 18 boys and 12 girls with a mean age
of 7.4 years (4 to 13) at the time of open reduction. The mean interval
to surgery, after the initial fracture, was 23.4 months (6 to 120).
Clinical grading used a Kim modified elbow score: radiological outcome
was recorded. The effect of the patient’s age, gender, duration
from initial injury, Bado classification, and annular ligament reconstruction
were analyzed. The mean follow-up was 42.2 months (15 to 20).Aims
Materials and Methods
The aim of this study was to investigate the changes in femoral
trochlear morphology following surgical correction of recurrent
patellar dislocation associated with trochlear dysplasia in children. A total of 23 patients with a mean age of 9.6 years (7 to 11)
were included All had bilateral recurrent patellar dislocation associated
with femoral trochlear dysplasia. The knee with traumatic dislocation
at the time of presentation or that had dislocated most frequently
was treated with medial patellar retinacular plasty (Group S). The
contralateral knee served as a control and was treated conservatively
(Group C). All patients were treated between October 2008 and August
2013. The mean follow-up was 48.7 months (43 to 56). Axial CT scans
were undertaken in all patients to assess the trochlear morphological
characteristics on a particular axial image which was established
at the point with the greatest epicondylar width based on measurements
preoperatively and at the final follow-up.Aims
Patients and Methods
Open reduction is required following failed conservative treatment
of developmental dysplasia of the hip (DDH). The Ludloff medial
approach is commonly used, but poor results have been reported,
with rates of the development of avascular necrosis (AVN) varying
between 8% and 54%. This retrospective cohort study evaluates the
long-term radiographic and clinical outcome of dislocated hips treated
using this approach. Children with a dislocated hip, younger than one year of age
at the time of surgery, who were treated using a medial approach
were eligible for the study. Radiographs were evaluated for the
degree of dislocation and the presence of an ossific nucleus preoperatively,
and for the degree of AVN and residual dysplasia at one and five
years and at a mean of 12.7 years (4.6 to 20.8) postoperatively.
Radiographic outcome was assessed using the Severin classification,
after five years of age. Further surgical procedures were recorded.
Functional outcome was assessed using the Pediatric Outcomes Data
Collection Instrument (PODCI) or the Hip Disability and Osteoarthritis
Outcome Score (HOOS), depending on the patient’s age.Aims

The aim of this prospective cohort study was to evaluate the
effectiveness of the neonatal hip instability screening programme. The study involved a four-year observational assessment of a
neonatal hip screening programme. All newborns were examined using
the Barlow or Ortolani manoeuvre within 72 hours of birth; those
with positive findings were referred to a ‘one-stop’ screening clinic
for clinical and sonographic assessment of the hip. The results
were compared with previous published studies from this unit.Aims

The aim of this study was to identify the association between
asymmetrical skin creases of the thigh, buttock or inguinal region
and pathological developmental dysplasia of the hip (DDH). Between 1 January 1996 and 31 December 2016, all patients referred
to our unit from primary or secondary care with risk factors for
DDH were assessed in a “one stop” clinic. All had clinical and sonographic
assessment by the senior author (RWP) with the results being recorded
prospectively. The inclusion criteria for this study were babies and
children referred with asymmetrical skin creases. Those with a neurological
cause of DDH were excluded. The positive predictive value (PPV)
for pathological DDH was calculated.Aims

High-quality clinical research in children’s orthopaedic surgery
has lagged behind other surgical subspecialties. This study used
a consensus-based approach to identify research priorities for clinical
trials in children’s orthopaedics. A modified Delphi technique was used, which involved an initial
scoping survey, a two-round Delphi process and an expert panel formed
of members of the British Society of Children’s Orthopaedic Surgery.

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

Preserving growth following limb-salvage surgery of the upper
limb in children remains a challenge. Vascularized autografts may
provide rapid biological incorporation with the potential for growth
and longevity. In this study, we aimed to describe the outcomes
following proximal humeral reconstruction with a vascularized fibular
epiphyseal transfer in children with a primary sarcoma of bone.
We also aimed to quantify the hypertrophy of the graft and the annual
growth, and to determine the functional outcomes of the neoglenofibular
joint. We retrospectively analyzed 11 patients who underwent this procedure
for a primary bone tumour of the proximal humerus between 2004 and
2015. Six had Ewing’s sarcoma and five had osteosarcoma. Their mean
age at the time of surgery was five years (two to eight). The mean
follow-up was 5.2 years (1 to 12.2).Aims
Patients and Methods
Displaced fractures of the lateral condyle of the humerus are
frequently managed surgically with the aim of avoiding nonunion,
malunion, disturbances of growth and later arthritis. The ideal
method of fixation is however not known, and treatment varies between
surgeons and hospitals. The aim of this study was to compare the
outcome of two well-established forms of surgical treatment, Kirschner
wire (K-wire) and screw fixation. A retrospective cohort study of children who underwent surgical
treatment for a fracture of the lateral condyle of the humerus between
January 2005 and December 2014 at two centres was undertaken. Pre,
intraoperative and postoperative characteristics were evaluated. A total of 336 children were included in the study. Their mean
age at the time of injury was 5.8 years (0 to 15) with a male:female
patient ratio of 3:2. A total of 243 (72%) had a Milch II fracture
and the fracture was displaced by > 2 mm in 228 (68%). In all, 235
patients underwent K-wire fixation and 101 had screw fixation. Aims

The aim of this study was to describe the epidemiology of closed
isolated fractures of the femoral shaft in children, and to compare
the treatment and length of stay (LOS) between major trauma centres
(MTCs) and trauma units (TUs) in England. National data were obtained from the Trauma and Audit Research
Network for all isolated, closed fractures of the femoral shaft
in children from birth to 15 years of age, between 2012 and 2015.
Age, gender, the season in which the fracture occurred, non-accidental
injury, the mechanism of injury, hospital trauma status, LOS and
type of treatment were recorded.Aims

A clicky hip is a common referral for clinical and sonographic
screening for developmental dysplasia of the hip (DDH). There is
controversy regarding whether it represents a true risk factor for
pathological DDH. Therefore a 20-year prospective, longitudinal,
observational study was undertaken to assess the relationship between
the presence of a neonatal clicky hip and pathological DDH. A total of 362 infants from 1997 to 2016 were referred with clicky
hips to our ‘one-stop’ paediatric hip screening clinic. Hips were
assessed clinically for instability and by ultrasound imaging using
a simplified Graf/Harcke classification. Dislocated or dislocatable
hips were classified as Graf Type IV hips.Aims
Patients and Methods
Despite the presence of screening programmes, infants continue
to present with late developmental dysplasia of the hip (DDH), the
impact of which is significant. The aim of this study was to assess
infants with late presenting dislocation of the hip despite universal
clinical neonatal and selective ultrasound screening. Between 01 January 1997 to 31 December 2011, a prospective, longitudinal
study was undertaken of a cohort of 64 670 live births. Late presenting
dislocation was defined as presentation after three months of age.
Diagnosis was confirmed by ultrasound and plain radiography. Patient
demographics, referral type, reason for referral, risk factors (breech
presentation/strong family history) and clinical and radiological
findings were recorded.Aims
Patients and Methods
It is well established that there is a strong association between
Perthes’ disease and worsening socioeconomic deprivation. It has
been suggested that the primary determinant driving this association
is exposure to tobacco smoke. This study aimed to examine this hypothesis. A hospital case-control study (n = 149/146) examined the association
between tobacco smoke exposure and Perthes’ disease, adjusting for
area-level socioeconomic deprivation. Tobacco smoke exposure was
assessed by parental questionnaire of smoking habits during pregnancy,
and by quantitative assay of current exposure using the urinary
cotinine-creatinine ratio, which is a widely used and validated
measure of tobacco smoke exposure.Aims
Patients and Methods
The aim of this study was to evaluate the correlation between
Salter’s criteria and Kalamchi’s classification of avascular necrosis
in patients treated for developmental dysphasia of the hip (DDH). The study involved a retrospective analysis of 123 patients (123
hips) with DDH treated by operative and non-operative reduction
before the age of two years, with a minimum follow-up of ten years.
Salter’s criteria (S1 to S4) were determined from radiographs obtained
at one to two years post-reduction, whilst the Kalamchi grade was determined
from radiographs obtained at ten or more years of age. Early post-reduction
radiographs were also used to evaluate the centre-head distance
discrepancy (CHDD) and the occurrence of a dome-shaped deformity
of the proximal femoral metaphysis (D-shaped metaphysis). The prognosis was described as good (Kalamchi grade K0 or KI),
fair (Kalamchi grade KII) or poor (Kalamchi grade KIII or KIV) for
analysis and correlation with the early Salter criteria, CHDD and
D-shaped metaphysis.Aims
Patients and Methods
After the initial correction of congenital talipes equinovarus
(CTEV) using the Ponseti method, a subsequent dynamic deformity
is often managed by transfer of the tendon of tibialis anterior
(TATT) to the lateral cuneiform. Many surgeons believe the lateral
cuneiform should be ossified before surgery is undertaken. This
study quantifies the ossification process of the lateral cuneiform
in children with CTEV between one and three years of age. The length, width and height of the lateral cuneiform were measured
in 43 consecutive patients with unilateral CTEV who had been treated
using the Ponseti method. Measurements were taken by two independent
observers on standardised anteroposterior and lateral radiographs
of both feet taken at one, two and three years of age.Aims
Patients and Methods
To assess the long-term effect of distal trochanteric transfer
(DTT) on the clinical and radiographic outcomes of patients with
Legg-Calvé-Perthes’ disease (LCPD) following a varus derotational
osteotomy (VDRO). For this single centre cross-sectional retrospective study we
analysed the data of 22 patients (24 hips) with LCPD who had greater
trochanteric overgrowth (GTO), following a VDRO performed in our
institution between 1959 and 1983. GTO was defined as an articular
trochanteric distance (ATD) of <
5 mm. We compared the radiographic
and clinical outcomes of patients who underwent DTT for GTO (ten
patients, ten hips) with those who did not (12 patients, 14 hips).
Age at presentation was 6.9 years (4 to 10) and 8.0 years (3.2 to
12) respectively. Symptoms associated with the hip and general quality
of life were assessed using the Harris hip score (HHS) and the Short Form
(SF)-36 questionnaires.Aims
Patients and Methods
This 20-year prospective longitudinal observational study aims to determine the incidence of pathological developmental dysplasia of the hip (DDH) in children referred with clicky hips and define the risk posed to inform neonatal hip screening programmes including the role of ultrasound. 355 children from 1997 to 2016 were referred with clicky hips to our “one stop” paediatric hip clinic under the local neonatal hip screening programme. Hips were assessed clinically for instability and by ultrasound using a simplified Graf classification. Dislocated or dislocatable hips were classed as Graf type IV.Purpose
Method
We share our experience in management of failed in-situ pinning in severe unstable Slipped Capital Femoral Epiphysis (SCFE) by surgical dislocation approach. A retrospective review of hip database from 2006 to 2013 showed 41 children underwent surgical dislocation for SCFE. We identified seven who had severe slip with failed in-situ pinning.Purpose
Method
To determine (i) the relationship between osteonecrosis and hip function, physical function and quality of life in adolescents and young adults treated for DDH; and (ii) how affected children change over 10 years. We included 109 patients (mean age 19.2 ± 3.8 years) with osteonecrosis and 30 age-matched patients without osteonecrosis following DDH treatment between 1992–2005. All completed valid patient-reported outcome measures to quantify their hip function (maximum score 100); physical function (maximum score 100); and quality of life (maximum score 1). Of these, 39 patients had been followed prospectively since 2006, allowing quantification of within-person changes over time. We graded all radiographs for severity of osteonecrosis, residual dysplasia, subluxation and osteoarthritis. We determined the association between patient-reported outcomes and radiographic severity of osteonecrosis using mixed-effects regression analysis; and repeated-measures analysis of variance to quantify person changes over time. We adjusted for age, prior operations and acetabular dysplasia.Purpose
Methods
This study compares outcomes in patients with complete congenital fibula absence, associated with severe lower limb deformity, treated with an amputation protocol to those using an extension prosthesis. 32 patients were identified. 9 patients (2M: 7F, median age at presentation of 22 yrs) utilized an extension prosthesis. 23 patients (16M: 7F, median age at presentation of 10 months) underwent 25 amputations during childhood: only two underwent tibial kyphus correction to facilitate prosthetic wear. Mobility was assessed using the SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Patients undergoing amputation were further subdivided by age, below and above 2 yrs at the time of surgery.Purpose
Method
The purpose of this study was to analyse inter- and intra-rater reliability of the Head-Shaft angle (HSA) on radiographs from a surveillance programme for children with cerebral palsy (CP). A high HSA is a risk factor for hip displacement in children with CP. To evaluate inter- and intra-rater reliability of the HSA, hip radiographs from the CP surveillance programme CPUP in the southern part of Sweden during the first half of 2016 were included in this study.Purpose
Method
The decision to undertake prophylactic pinning to prevent contralateral slipped upper femoral epiphysis (SUFE) remains controversial; we hypothesised that the grade of initial SUFE could predict the grade of a second SUFE and risk of poor outcome. We retrospectively reviewed radiographs of all children who presented to Alder Hey with a new diagnosis of SUFE between 2007–2014. Of those who developed a contralateral SUFE, grade of first and second SUFE was determined radio-graphically using %
slip and Southwick angle on frog lateral radiograph.Purpose
Method
To assess the use of radiographic measurement compared to descriptive classification in the evaluation of Perthes'
disease. Fifteen consultant Paediatric Orthopaedic surgeons, members of the BOSS Collaborative from different UK centres, were asked to rate a series of 100 healed AP radiographs of hips affected by Perthes'
Disease from the Liverpool Perthes'
Disease Register using the Stulberg'
s grading. Two independent observers categorised roundness error using Digitimizer™ software. Kappa scores were used to determine the inter-observer concordance amongst the 15 observers for Stulberg classification. Lin concordance was used to determine roundness error assessment. The relationship between the two outcomes was explored statistically and graphically; considering the mean Stulberg grade recorded by the 15 observers as a continuous outcome.Purpose
Method
This study re-examined the influence of the head shaft angle (HSA) on hip dislocation in a large cohort of children with cerebral palsy (CP). The radiographs of GMFCS Level III – V children from a surveillance programme database were analysed and migration percentage (MP) and HSA measured. The first radiograph of each patient was taken to remove the effect of the surveillance programme. The most displaced hip in each child, by MP, was used for analysis and the corresponding HSA measured. Hip displacement was defined as MP >
40%
and logistic regression was used to adjust for HSA, GMFCS, age and sex.Purpose
Method
This study aimed to objectively define gait derangements and changes before and after Tibialis Anterior Tendon Transfer surgery in a group of patients treated using the Ponseti method. 21 feet in 13 patients with Ponseti treated clubfoot who showed supination in swing on clinical examination, underwent gait analysis before, and approximately 12 months after, Tibialis Anterior Tendon transfer. 3–4 weekly casts were applied prior to the surgery, which was performed by transfer of the complete TA tendon to the lateral cuneiform. A parental satisfaction questionnaire was also completed.Purpose
Methods
To assess outcomes of manipulating upper extremity fractures with conscious sedation compared with formal reduction and casting in theatre under general anaesthesia and image intensifier control. Prospective six month period all patients presenting to the Emergency Department with a both bone forearm or distal radial fracture that was deemed suitable for closed reduction and casting where included in the study. All fractures deemed to require instrumentation were excluded.Purpose
Method
To clarify the true association with pathological DDH and ASC (asymmetrical skin crease). Between 1st January 1995 and 31st December 2015 all paediatric referrals with suspected hip instability were assessed in a one-stop DDH clinic. All patients had clinical and sonographic assessment with results prospectively recorded onto a database.Purpose
Method
This study aims to report the radiological corrections achieved and complication profile of Peri-Acetabular Osteotomy (PAO) undertaken through the minimally invasive approach. 106 PAOs were performed in 103 patients, by senior author, using a minimally invasive approach from 2007 to 2015. Pre- and post-operative radiographs were reviewed and the degree of acetabular re-orientation was analysed. Case notes were examined retrospectively to identify haemoglobin levels and complications across two sites.Purpose
Method
The aim of this study was to identify if perioperative outcomes were different in patients with cerebral palsy undergoing unilateral or bilateral hip reconstruction. All consecutive hip reconstructions for cerebral palsy performed by the senior author (FNT) within a tertiary-referral centre were identified between January 2012 and July 2016. Patients were stratified by age, gender, GMFCS and side of procedure. Length of surgery, pre- and post- operative haemoglobin, length of stay and immediate post-operative complications were measured.Purpose
Method
There is concern that the positive predictive value (PPV) of neonatal screening for instability may have deteriorated over recent years, this study aims to evaluate this. This is a prospective observational longitudinal study from 2012 – 2016. Patients that were referred from paediatric neonatal screening with hip instability (Ortolani / Barlow positive, clunks) were identified and underwent ultrasound and clinical examination in the one stop hip clinic by the senior author. Referrals were taken from a range of screeners from paediatric doctors to midwives and advanced neonatal practitioners. Syndromic or neurological dislocated hips were excluded. The outcome measures were the presence of a subluxated / dislocated hip on ultrasound as per Graf and Harcke classification and a positive provocative manoeuvre on examination. This allowed a PPV to be evaluated for both ultrasound and clinical examination.Purpose

This report compares midterm results of open neck osteoplasty +
neck osteotomy vs arthroscopic osteoplasty for severe Slipped Capital Femoral Epiphysis (SCFE). Database from 2006 to 2013 identified 22 patients out of 187 operations for SCFE. 12 underwent Open Neck Osteotomy (ONO) and osteoplasty by Ganz surgical dislocation approach. 10 underwent Arthroscopic Osteoplasty (AO). The mean follow-up for the ONO and AO groups were 59 (46 – 70), 36.1 (33 – 46) months respectively.Purpose
Method
The purpose of this paper is to describe the outcomes of major hip surgery for children with cerebral palsy and communication difficulties using a validated health related quality of life measure and a validated pain score. Children with hypertonic bilateral cerebral palsy (CP) GMFCS levels IV and V, 2–15 years old, having femoral +
/- acetabular osteotomies for hip displacement were included if their ability to communicate necessitated the use of the CPCHILD (Caregiver Priorities and Child Health Index of Life with Disabilities) and PPP (Paediatric Pain Profile). The underlying indication for surgery was a hip migration index of more than 40%
. CPCHILD and PPP questionnaires were completed face-to-face with the parents or carers at baseline, at 3 months after surgery and at 6 months after surgery.Purpose
Method
This study evaluated the acceptability of performing manipulations with intranasal diamorphine and inhaled Entonox to parents of children presenting to our Emergency Department. 65 fractures were manipulated in the Emergency Department in a 4-month timespan. Parents were invited to complete a questionnaire to indicate their experience with the procedure. Fracture position post-reduction was calculated as well as conversion rate to surgery. 32 patients who were admitted and had their forearm fractures managed in theatre were also asked to complete the questionnaire as a comparison group.Purpose
Method
Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in children 9–15 years old. The epidemiology for SCFE in the total population of Sweden has not yet been described. In a prospective cohort study, we analysed pre- and postoperative radiographs and medical records for all children treated for SCFE in Sweden 2007–2013, and noted demographic data, severity of slip, and surgical procedures performed.Purpose
Methods
This pilot study aimed to evaluate prospectively the use of inlet
radiographs of the hip as an alternative method of the assessment
of reduction after the surgical treatment of developmental dysplasia
of the hip (DDH). The children in this study underwent surgery between January
2013 and January 2015. All had inlet radiographs and CT scans post-operatively.
Data were analysed by determining inter-observer reliability and
intra-observer reproducibility, using the kappa value (K). Differences
were settled by discussion between the two observers until a consensus
was reached. The sensitivity and specificity of the radiographic
and CT results were compared. A total of 26 radiographs were obtained
from 23 children, with a mean age of 2.38 years (one to five).Aims
Patients and Methods
Following the introduction of national standards in 2009, most
major paediatric trauma is now triaged to specialist units offering
combined orthopaedic and plastic surgical expertise. We investigated
the management of open tibia fractures at a paediatric trauma centre,
primarily reporting the risk of infection and rate of union. A retrospective review was performed on 61 children who between
2007 and 2015 presented with an open tibia fracture. Their mean
age was nine years (2 to 16) and the median follow-up was ten months
(interquartile range 5 to 18). Management involved IV antibiotics,
early debridement and combined treatment of the skeletal and soft-tissue injuries
in line with standards proposed by the British Orthopaedic Association.Aims
Patients and Methods
Our aim was to describe the mid-term appearances of the repair
process of the Achilles tendon after tenotomy in children with a
clubfoot treated using the Ponseti method. A total of 15 children (ten boys, five girls) with idiopathic
clubfoot were evaluated at a mean of 6.8 years (5.4 to 8.1) after
complete percutaneous division of the Achilles tendon. The contour
and subjective thickness of the tendon were recorded, and superficial
defects and its strength were assessed clinically. The echogenicity,
texture, thickness, peritendinous irregularities and potential for
deformation of the tendon were evaluated by ultrasonography.Aims
Patients and Methods
Extendible endoprostheses have been available for more than 30
years and have become more sophisticated with time. The latest generation
is ‘non-invasive’ and can be lengthened with an external magnetic
force. Early results have shown a worryingly high rate of complications
such as infection. This study investigates the incidence of complications
and the need for further surgery in a cohort of patients with a
non-invasive growing endoprosthesis. Between 2003 and June 2014, 50 children (51 prostheses) had a
non-invasive growing prosthesis implanted for a primary bone sarcoma.
The minimum follow-up was 24 months for those who survived. Their
mean age was 10.4 years (6 to 14). The incidence of complications
and further surgery was documented.Aims
Patients and Methods
To determine the normal values and usefulness of the C1/4 space
available for spinal cord (SAC) ratio and C1 inclination angle,
which are new radiological parameters for assessing atlantoaxial
instability in children with Down syndrome. We recruited 272 children with Down syndrome (including 14 who
underwent surgical treatment), and 141 children in the control group.
All were aged between two and 11 years. The C1/4 SAC ratio, C1 inclination
angle, atlas-dens interval (ADI), and SAC were measured in those
with Down syndrome, and the C1/4 SAC ratio and C1 inclination angle
were measured in the control group.Aims
Patients and Methods
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

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
To compare the structural durability of hydroxyapatite-tricalcium
phosphate (HATCP) to autologous iliac crest bone graft in calcaneal
lengthening osteotomy (CLO) for pes planovalgus in childhood. We present the interim results of ten patients (HATCP, n = 6
and autograft, n = 5) with a mean age of 11.5 years (8.2 to 14.2)
from a randomised controlled non-inferiority trial with six months
follow-up. The primary outcome was the stability of the osteotomy
as measured by radiostereometric analysis. A non-inferiority margin
of ≤ 2 mm osteotomy compression was set.Aims
Patients and Methods
We present the clinical and radiographic outcome of 81 children
with Gartland type I to III supracondylar humeral fractures at a
minimum follow-up of ten years (mean 12.1 years; 10.3 to 16.1) following
injury. The clinical and functional outcomes are compared with normal
age- and gender-matched individuals. The population-based study
setting was first identified from the institutional registries;
the rate of participation was 76%. Controls were randomly selected
from Finnish National Population Registry.Aims
Patients and Methods
The treatment of developmental dysplasia of the hip (DDH) in children remains controversial, we describe the clinical and radiological outcomes of 47 hips in 43 children treated with open surgery by one surgeon between 2004 and 2008 for DDH. The mean age at operation was 25 months (5 to 113) with a mean follow up of 89 months (22 to 169). 46 hips had an anterior open reduction, 1 had a medial approach performed and 16 had anterior open reductions only. 5 of the primary operations also had a pelvic osteotomy, 7 had a femoral osteotomy and 18 had a combined femoral and pelvic osteotomy. 7 (15%) of the hips required a second operation for dislocation, subluxation or dysplasia. At the latest follow up 40 of the 45 hips where Severin grades were recordable (89%) were graded as excellent or good, Severin class I or II. Clinically significant AVN (grade II to III according to the Kalamchi and MacEwen classification) was seen in 5 (11%) of the hips. We found a pelvic osteotomy to be a risk factor for AVN (p 0.02) and age at operation to be a risk factor for poor morphology at final follow up (p 0.03). We proceed to open surgery in patients over 12 months old or those with failed closed reduction. Over 18 months old a pelvic osteotomy should be performed in selective cases depending on intra-operative stability, but we will now consider doing this as a staged procedure and delaying the osteotomy for a period of time after open reduction to reduce the risk of AVN. We will also have a much lower threshold for performing a femoral shortening osteotomy in these patients as open reduction with Salters osteotomy alone tended to have a poorer outcome.
The aim of our survey was to study the current practice to manage DDH in UK by the members of the British Society for Children's Orthopaedic Surgery. An online questionnaire link to ask about the management of DDH was emailed to 204 members of the British Society for Children's Orthopaedic Surgery. The response rate was 39%. 73% respondents have a local screening programme, 19% screen only high risk children and 8% had no screening programme. Pavlik harness was used by 87% respondents for Graf Type 2, 96% for Graf type 3 and 90% for Graf type 4. 14% respondents will only observe for Graf Type 2. 36% respondents will follow up children every week, 45% every 2 weeks, 3% every 3 weeks, 9% every 4 weeks, 4% every 6 weeks and 3% will decide the follow up according to severity of DDH and treatment.1.3% respondents will follow up these patients for 6 months, 13% for 12 months, 10.5% each for 24 months, 36 months, 48 months and 50% until skeletal maturity. After the failure of initial splintage, 7% respondents will consider surgery immediately, 13.5% at 3 months, 36.5% at 6 months, 4% at 9 months, 28% at 12 months, 5.4% according to HIP-OP Trial and 5.6% according to the situation. There was no consensus about the treatment of DDH. 73% respondents have a local screening programme. The most common splintage method used was Pavlik harness. 45% respondents will follow up children every 2 weeks following the start of treatment. 50% respondents will follow up these patients until skeletal maturity. 36% respondents will consider surgery at 6 months following the failure of splintage. This survey highlights the fact that the management of DDH is an art based on the scientific evidence, parent's choice and personal expertise.
Originally used for correction of angular malalignment, 2 hole plate epiphyseodesis has recently gained popularity in paediatric orthopaedic practice for the correction of leg length discrepancy. In this study we aim to assess the efficiency of guided growth plates in correcting leg length discrepancy Thirty-three children treated for leg length discrepancy with guided growth plates (“8-Plate”, Orthofix, Inc and “I-Plate”, Orthopediatrics) in a tertiary referral centre were retrospectively analysed. Medial and Lateral plates were inserted for symmetrical growth reduction and patients were followed up with clinical and radiological assessment. Thirty patients had distal femoral epiphyseodesis and three had proximal tibial epiphyseodesis. Leg lengths and individual bone lengths were measured from pre and post – operative radiographs. The angle between the screws was measured from radiographs taken intra operatively and at the time of final follow up to assess screw divergence with growth. Efficiency was calculated as the ratio of growth inhibition achieved to the projected discrepancy at maturity if left untreated. At a mean follow up of 17 months (4–30 m) leg length discrepancy improved from a mean of 30 mm (50–15mm) to 13 mm (2.5–39mm) (p < 0.01). The angle between screws increased from 6 degrees to 26 degrees over the follow up period. Efficiency was found to be 66%. There were 5 patients with angular deformity who needed plate removal and 2 patients developed superficial infection that responded to oral antibiotics. Epiphyseodesis using guided growth plates is an effective way to correct leg length discrepancy as it is a reversible procedure. Patients undergoing this treatment should be kept under close follow up to prevent development of angular malalignment. Inserting the screws in a divergent fashion at the outset may increase the effectiveness of this procedure.
This pilot study aims to investigate the utility and feasibility of a unique upright MR scan for imaging hips affected by Legg-Calve-Perthes Disease (LCPD) with patient standing up, in comparison to the standard supine scans. Protocol development using this unique upright MRI included healthy adult and child volunteers. Optimum patient positioning in a comparable way between supine to standing was assessed. The balance between shorter scan time (to what a child can tolerate) and longer scan time (for better image acquisition). The study protocol has begun in 2 children with LCPD. Patient recruitment continues. Early results indicate a dynamic deformity of the femoral head in early stage LCP disease. Femoral epiphysis height decreased on standing (7.8 to 6.8mm), width increased on standing (16.6 to 20.9mm) and lateral extrusion increased (3.5 to 4.1mm). Overall epiphyseal shape changed from trapezoidal (LCP femoral head when supine) to flattened triangular (LCP femoral head when standing). Differences were thus demonstrated in all parameters of bony epiphyseal height, width, extrusion and shape of a femoral head with LCP Disease when the child stood and loaded the affected hip. Satisfactory image acquisition was possible with Coronal T1 GFE sequences, with both hips in the Field of View. 2.5min scans were performed with the child standing first, then supine. Hip position was comparable when standing and supine. Longer scans were not tolerated by younger children, more so those with LCP disease. To our knowledge this is the first reported use of standing MRI in LCPD. A dynamic deformity has been demonstrated, with flattening, widening and worsened lateral extrusion when the child is standing compared to supine. This proof of concept investigation demonstrates the feasibility of upright MRI scanning and may demonstrate previously undetected deformity.
This study sought to determine the genetic contribution of Perthes' disease, using the world's largest twin-registry. We extracted all twin pairs from the Danish Twin Registry (DTR) in which at least one individual had Perthes' Disease. The DTR captures every twin pair born alive in Denmark. Those with Perthes' disease were identified using health record linkage to the Danish Morbidity Record. Probandwise concordance was calculated to describe the likelihood that any given individual had LCPD if their co-twin was also diagnosed. There were 81 twin pairs; 10 monozygotic (MZ), 51 dizygotic (DZ), and 20 unclassified (UZ). There was no association between birth weight and being the affected co-twin. Four pairs (two dizygotic and two unclassified) were concordant for LCPD, which is greater than would be expected assuming no familial aggregation. There were no concordant MZ twin pairs. The overall probandwise concordance was 0.09 (95% CI 0.01–0.18): 0.00 for the MZ, 0.08 (95% CI 0.00–0.18) for the DZ, and 0.18 (95% 0.00–0.40) for the UZ twin pairs. This study found evidence of familial clustering in LCPD but did not demonstrate a genetic component. The absolute risk that a co-twin of an affected individual will develop LCPD is low, even in the case of MZ twin pairs.
We present the long term outcome from children with Legg-Calves-Perthes (LCPD) treated at our unit. Patients treated for LCPD were identified retrospectively from an orthopaedic database between 1990 and 2005. Patient demographics, clinical examination, treatment and Herring classification were recorded at initial presentation and treatment. Long-term clinical and radiological follow-up was also recorded. 85 patients were identified and 4 excluded due to insufficient data giving a total of 81 patients. Of these, 58 were male and 23 female. Average age range at presentation was 6.5 years (range 1.5–14 yrs). The side affected was 34 right, 35 left, 24 bilateral giving 93 hips in total. Time between presentation and diagnosis averaged 4.7 months (range 0–48 months). In patients with recorded clinical examination 87% had reduced abduction and 88% reduced internal rotation. Treatment was largely conservative with 12 hips (13%) undergoing surgery within the first 4 years of diagnosis. Radiographs were available for 71 hips. Herring classification was A-12, B-22, C-37. Long term follow up averaged 16 years (range 10–25 yrs). Stulberg grading was available in 67 hips; Grade I 13, Grade II 21, Grade III 19, Grade IV 18 and Grade V 6. There were ongoing issues (mostly pain) in 18 hips, 5 of which required a subsequent operation. No correlation was found between abduction and Stulberg grade (p-value = 0.7). A correlation was found between delay in diagnosis of ≥6 months and the need for a subsequent operation (p-value = 0.0408). The overall trend as expected showed that a better Herring classification generally led to a more favourable Stulberg classification. Range of motion was not predictive for Stulberg grade. The need for further surgical intervention for symptoms at long term follow up was 0.05%.
We wished to examine the effectiveness of tibial lengthening
using a two ring Ilizarov frame in skeletally immature patients.
This is a potentially biomechanically unstable construct which risks
the loss of axial control. We retrospectively reviewed a consecutive series of 24 boys and
26 girls, with a mean age of 8.6 years (4 to 14), who underwent
52 tibial lengthening procedures with a mean follow-up of 4.3 years
(4.0 to 16.9). Tibial alignment was measured before and after treatment
using joint orientation lines from the knee and a calculation of
the oblique plane axis.Aims
Patients and Methods
To evaluate the safety and efficacy of treating patients with Graf IIa developmental hip dysplasia. The management of the developmentally immature Graf Type IIa dysplastic hip is controversial. Some authors advocate early treatment with an abduction harness whilst others adopt watchful waiting. At our institution selective sonographic assessment for developmental dysplasia of the hip (DDH) was established in 1997 with prospective data collection. All infants diagnosed with Graf Type IIa hip(s) were treated with either a Pavlik harness or double nappies, with clinical and sonographic follow up until normalisation. Pelvic radiographs were routinely performed at 8 and 18 months follow up for assessment of residual dysplasia and/or complications of treatment. We evaluated the safety and efficacy of all treated patients between 2005 and 2013. Complete clinical and radiological follow up (mean 2.1 years, 0.7–6.5) was available for 103 of 118 infants. 69 were treated with a Pavlik harness and 49 with double nappies. The chosen treatment was successful in 110 hips with no documented complications, well developed ossific nuclei on follow up radiographs, and no further treatments undertaken. In the double nappy group 4 infants deteriorated sonographically so were changed to a Pavlik harness with subsequent normalisation and successful treatment. 3 patients required VDRO at age 18 months (17–20) and 1 patient required closed reduction and spica cast treatment at age 11 months. No further complications arose in this group. The 15 patients lost to follow up had successful initial treatment but failed to attend for radiographic review. Both Pavlik harness and double nappies are safe treatment modalities for Type IIa hip dysplasia. However, sonographic deterioration was observed in both groups with surgical intervention required in the minority, supporting the ongoing treatment of these immature hips.
The aim was to assess the value of the GP 6–8 week hip examination. In a 15-year prospective observational longitudinal cohort study, every infant referred by the GP with suspected pathological developmental dysplasia of the hip (DDH) had their hip joints clinically and sonographically examined in a specialist hip screening clinic. Graf Type IV and dislocated hips were classified as pathological. Screening failures were defined as those who had not been identified by the 6–8 week check and presented with late instability. Secondary univariate and multivariable analysis was performed to determine which clinical findings are predictive of instability. 64,518 infants underwent the 6–8 week GP check. Of 176 referrals, 5 had pathological hips. 13 screening failures, presented between the ages of 17 and 80 weeks. The 6–8 week check has a sensitivity of 28% and a specificity of 99.7%. Univariate analysis revealed positive Ortolani tests and patients referred as ‘unstable hip’ to be significant predictors of hip pathology. Clicky hips, asymmetric skin creases, and leg length inequality were not predictive of pathological hips. A multivariable model showed a positive Ortolani test to be the sole independent predictor of instability at 6–8 weeks. This is the first attempt to test the validity of the 6–8 week GP clinical hip check. A low rate of hip pathology was identified. The high rate of false negatives raises questions about the value of screening at this age. At 6–8 weeks, clinical signs of hip instability are unreliable as hips become irreducible and stiff. Based on our findings, we recommend that at 6–8 weeks, referrals are only made if the Ortolani test is positive. We advocate the reintroduction of the 8-month check, including an assessment for limited hip abduction, which may improve the detection rate of those missed by initial screening.
The aim of this study was determine if the detection of pathology in children with a limp can be optimised by screening with blood tests for raised inflammatory markers. The entry criteria for the study were children (0–15 years) presenting to our hospital Emergency Department from 2012–2015 with a non-traumatic limp or pseudoparalysis of a limb, and no sign of fracture or malignancy on plain radiographs. ESR and CRP blood tests were performed along with other standard investigations. Children with ESR or CRP over 10 underwent MRI scan of their area of pain or tendernesss, with those under 7 years old having general anaesthetic. MRI provided the diagnosis in cases of osteomyelitis, pyomyositis, fasciitis, cellulitis, discitis, as well as non-infective conditions such as malignancy and fracture not visible on plain radiographs. Where a joint effusion was present, the diagnosis of septic arthritis was made from organisms cultured following surgical drainage, or high white cell count in joint fluid if no organisms were cultured. The study was completed once data from 100 consecutive children was available. 64% of children had an infective cause for their symptoms (osteomyelitis, septic arthritis, pyomyositis, fasciitis, cellulitis or discitis). A further 11% had positive findings on MRI from non-infective causes (juvenile idiopathic arthritis, cancer, or occult fracture). The remaining 25% had either a normal scan, or transient synovitis. ESR was a more sensitive marker than CRP, since ESR was raised in 97% of those with abnormal scans, but CRP in only 70%. There were no complications from any of the GA MRI scans. Conclusion: This shows that MRI imaging of all children with a limp and either raised ESR or CRP is a sensitive method to minimise the chance of missing important pathology in this group, and is not wasteful of MRI resources.
The aim was to determine reliability in treatment threshold based on USS angular measurements between observers involved in the DDH hip screening programme at the NOC and assess the effect of image orientation on the accuracy of these measurements. 3 independent observers measured alpha and beta angles on bilateral hips in 10 consecutive patients seen in the DDH hip screening clinic. All scans were performed by a single radiographer and observers used the same set of USS images for a given patient. Each observer measured alpha and beta angles a total of 4 times: conventional ultrasound image projection (with the ilium horizontal) (round 1), Graf's anatomical projection (round 2), and both techniques repeated 1 month later (round 3 and 4 respectively) to assess intra-observer reliability. To determine its effect on treatment threshold taking into account alpha and beta angles and patient's age, the consistency between observers' management recommendations was evaluated for each round. Possible outcomes were: 1) patient discharged, 2) no treatment needed yet, but follow-up required, 3) start treatment. Intra-observer reliability for conventional projection was moderate (Kappa 0.58), and improved for anatomical projection (Kappa 0.65). Inter-observer reliability, as a surrogate measure of consistency in management recommendations between observers, ranged from fair to moderate across the 4 rounds (Kappa 0.30 – 0.50). However, contrary to previous recommendations, reliability was better with conventional projection (Kappa 0.41 (95% CI 0.11–0.72)) compared to anatomical projection (Kappa 0.36 (95% CI −0.01–0.73)). The overall agreement in management recommendations, pooling all results across 4 rounds, was 51.3% (Kappa 0.39 (95%CI 0.15–0.63)). This audit supports the argument that anatomical image projection improves intra-observer consistency. However, as with all USS measurements, angular measurements were highly user dependent and treatment threshold based on USS may not be as consistent as anticipated.
To evaluate effectiveness and safety of acute ulnar lengthening osteotomy in Madelung's deformity associated with Hereditary Multiple Exostoses (HME) Seventeen ulnas in 13 patients had acute ulnar lengthening for HME associated forearm deformity. Defined radiographic parameters were compared pre- and post-operatively using student's t-test; ulnar variance, carpal slip, radial bowing, radial articular angle. All complications were noted. Mean follow-up was 27 months (range 1.5 – 72months). An increase in ulna length by a mean of 15.4mm (range 4.5 – 29.3mm) was achieved acutely, corresponding to an increase of 9.3% of total ulnar length. Negative ulnar variance was improved from a pre-operative mean of 12.4mm (range 6.1–16.5mm) to a post-operative mean of 4.6mm (range 0–11.25mm) (p=<0.00001). Carpal slip was significantly improved by a mean of 2.2mm (p=0.02). No significant change in radial bowing (p=0.98) or radial articular angle (p=0.74) was observed. Inter-rater reliability was excellent (r=0.96, Pearson Correlation). Three patients required second procedures for recurrence of deformity at 18 months – 6 years following their primary operation. There were no incidences of compartment syndrome, neurovascular injury nor infection. One ulna fractured intra-operatively requiring a longer plate. One patient had a non union which united on revision surgery. Significant radiographic improvements in forearm and wrist alignment were seen with acute ulnar lengthening. The procedure is safe, with no compartment syndrome nor neurovascular injury and low complications rate. Recurrence rates in the skeletally immature patients are comparable to that reported with gradual lengthening. Acute ulnar lengthening for forearm deformity associated with HME has been demonstrated to be a safe, reproducible and effective surgical procedure.
To evaluate the outcome of combined tibialis anterior tendon shortening (TATS) and calf muscle-tendon lengthening (CMTL) in spastic equinus. Prospectively collected data was analysed in 26 patients with hemiplegic (n=13) and diplegic (n=13) cerebral palsy (CP) (GMFCS level I or II, 14 males, 12 females, age range 10–35 years; mean 16.8 years). None had received botulinum toxin A injections or surgery in the preceding six and 12 months respectively. All patients had pre-operative 3D gait analysis and a further analysis at a mean of 17.1 months (± 5.6months) after surgery. None was lost to follow-up. Twenty-eight combined TATS and CMTL were undertaken and 19 nineteen patients had additional synchronous multilevel surgery. At follow-up 79% of patients had improved foot positioning at initial contact. Statistically significant improvements were seen in the Movement Analysis Profile for ankle dorsi-/plantarflexion (4.25, p=0.032), maximum ankle dorsiflexion during swing phase (11.68°, p<0.001), and Edinburgh Visual Gait Score (EVGS) (4.85, p=0.014). Diplegic patients had a greater improvement in the EVGS than hemiplegics (6.27 -vs- 2.21, p = 0.024). The originators of combined TATS and CMTL showed that it improved foot positioning during gait. The present study has independently confirmed favourable outcomes in a similar patient population and added additional outcome measures, the EVGS, foot positioning at initial contact, and maximum ankle dorsiflexion during swing phase. Study limitations include short term follow-up in a heterogeneous population and that 19 patients had additional surgery. However, distinguishing between the natural history of CP and interventions and isolating the effects of one intervention from others in multilevel surgery are well recognised difficulties in cohort studies in CP. TATS combined with CMTL is a recommended option for spastic equinus in ambulatory patients with CP.
Due to abnormal neuromuscular development, functional capability in children with cerebral palsy is often severely compromised. Single event multi-level surgery (SEMLS) is the gold standard surgical treatment for patients with cerebral palsy. It has been demonstrated to improve gait, however, how standing posture is affected is unknown. The aim was to investigate the effect of SEMLS in patients with spastic cerebral palsy on walking and standing posture using 3D gait analysis. Participants were identified from the One Small Step Gait Laboratory database. Standardised 3D-Gait analysis was performed within 2 years pre- and post-SEMLS. Gait abnormality was measured using the Gait Profile Score (GPS) index; standing abnormality was measured using the newly-developed Standing Profile Score (SPS) index. A control group (n=20) of age/sex-matched CP patients who did not undergo surgery were also assessed. 104 patients (73 boys, 31 girls) with spastic cerebral palsy underwent SEMLS with appropriate pre- and post-gait analyses (2000–2015). 91 patients had bilateral limb involvement, 14 had unilateral limb involvement. Average age at surgery was 10.38 years (range 4.85–15.60 years). A total of 341 procedures were performed, with hamstring and gastrocnemius lengthening representing approximately 65% of this. There was a 20% mean improvement in walking (GPS reduced 2.4°, p<0.001) and standing (SPS reduced 3.4°, p<0.001) following SEMLS. No improvement was noted in the control group. Significant correlations were observed between the changes in SPS and GPS following surgery (r2, p<0.001). Patients with poorer pre-operative standing posture (SPS) reported the most significant improvement following surgery. We confirmed improvement in walking following SEMLS using the Gait Profile Score (GPS). This is the first paper to report that standing posture is also improved following surgery using a novel index, the Standing Posture Score (SPS). SPS could be adopted as a tool to assess functional capability and predict post-operative changes.
The aim was to examine the descriptive epidemiology of Slipped Capital Femoral Epiphysis, with respect to geography and time. We extracted all children with a diagnosis of Slipped Capital Femoral Epiphysis from the Clinical Practice Research Database between 1990 and 2014 (24 years). CPRD is the world's largest database of primary care, which encompasses 8% of the UK population. CPRD was linked to Hospital Episode Statistics, and a validation algorithm applied to maximise sensitivity and specificity of the cases finding methodology. Poisson confidence intervals were calculated, and poison regression used. 596 cases of SCFE were identified. The internal validation algorithm supported a SCFE diagnosis in 88% cases. The age and sex distribution of cases mirrored that in the literature, offering external validity to the cases identified. There was no significant change in the incidence of SCFE over the 24-year study period, with the overall incidence being 4.8 cases per 100,00 0–16 year olds. There was no significant geographic variation in SCFE within the UK. There was a positive association with rising socioeconomic deprivation (p<0.01). There was no seasonal variation in presentation. This study found no evidence to support the common belief that SCFE incidence is increasing, and for the first time demonstrated an association with socioeconomic deprivation. The results are important for considering the feasibility of intervention studies, and offer insights into the disease aetiology.
The study describes a technique of tibial autograft to augment posterior instrumented spinal fusion in a population of paediatric patients with severe idiopathic, neuromuscular or syndromic scoliosis who are at a higher risk of postoperative pseudarthrosis and reports patient outcomes in terms of union rate, donor site morbidity and cost. Patients were identified from a review of waiting list and operating room records between 2007–2014. Surgery was performed by the senior author. Information on patient demographics, underlying diagnosis, age at surgery, revision surgery and length of follow-up was obtained from clinic notes. Parents of children were followed up with a structured telephone questionnaire regarding ambulatory status, post-operative pain, infection, further surgery and general satisfaction. Four hundred and nine patients underwent posterior instrumented spinal fusion, during the study period. Forty-two patients’ fusions were augmented with tibial graft, 40 of whom participated in the study. There were no cases of donor site infection, compartment syndrome, tibial fracture or perioperative mortality. In 85% of cases leg pain had resolved within 6 weeks, and 100% within 6 months of surgery. There were 6 cases of revision spinal surgery, 3 for infection, 2 for sacroiliac screw removal and 1 for sacroiliac screw revision. There were no clinical cases of spinal pseudarthrosis in this series. All parents were satisfied by the clinical outcome of both the tibial and spinal surgeries. Spinal fusion utilising tibial autograft is advocated as a simple, safe and cost-effective method of providing significant structural autograft to support fusion for a population of patients with high risk of junctional pseudarthrosis. With the exception of transient post-operative pain, the procedure was without any serious donor site morbidity. The outcomes of this study were as expected and in keeping with previous reports.
The aim of the study was to review the effectiveness of rigid IM nailing in stabilisation and deformity correction of lower limb long bones in adolescents with metabolic bone disease which to our knowledge has not been studied before. Medical records and radiographs were retrospectively reviewed looking at indications, deformity correction, number of osteotomies-if needed, bone healing, time to healing and incidence of complications. Between Aug 2010 and Mar 2015 fifteen patients (24 segments) had rigid IM nailing. Ten patients had Osteogenesis Imperfecta, four with McCune Albright syndrome and one with hypophosphatemic rickets. 22 femora and two tibiae were IM nailed. The mean age of the patients was 13.1 (9.6–16.75 years). Eleven out 24 segments were previously rodded. Eight segments were for acute fractures. 13 bones had significant deformities requiring corrective osteotomies. One patient had previous fracture non union. All patients were allowed to partial weight bear immediately postoperatively and were fully mobile six weeks following surgery. Mean follow up was 24 months (3–51 months) post-operatively. All deformities were corrected. All fractures and osteotomies radiologically united. Mean radiological union time was 5.5 months (6 weeks – 11 months). Patients with acute fractures had mean radiological union time of 4 months. Patients who had osteotomies had a mean radiological union time of 7.1 months. The patient with previous non union had BMP at the same time and radiologically healed in 10 months. Two patients had persistent bisphosphonate osteotomy lines but were asymptomatic. One patient had removal of a prominent distal locking screw and one had persistent Trendelenburg gait. Rigid intramedullary nailing is effective in stabilisation and deformity correction of long bones in adolescent patients with brittle bone disease. The technique has a low complication rate. We recommend the use of this technique in paediatric limb reconstruction in managing metabolic bone conditions.
We present a review of our Specialist Physiotherapy clinic for normal physiological variations of the lower limb (SPNV) clinics, demonstrating them to be clinically effective and cost effective. Children with normal variation of rotational profile and limb angulation present much anxiety to parents and primary care. Providing consultation: to eliminate significant pathology and reassure families, is an important service that a Paediatric Orthopaedic department provides. In our tertiary referral department we have a Specialist Physiotherapy led clinics into which primary care practitioners refer children with whom there are concerns about lower limb development variation. The (SPNV) Clinic was first set up by a Consultant and Senior Physiotherapist in 1999. The aim of the clinic was to reduce the waiting times for incoming referrals but ensuring they are seen in an appropriate environment by an experienced health care professional. Clinics are run by Senior Specialist Physiotherapists, alongside Consultant clinics who are available for advice and direction. This provides security for the physios, the Trust and the patient. Over 15 years there have been more than 4000 patient visits to this clinic. Over 80% were new patient visits. 70% of these visits were discharged in one or two reviews. 97.4% of new referrals were discharged without subsequent review by an orthopaedic surgeon. The most common conditions reviewed were Genu valgum (25%), Genu Varum (16%), intoeing (17%) and flexible flat feet (11%). The clinic has proven to be cost effective as well in drawing in up to £500,000 revenue into the trust in a single year. The department has been approached by other trusts to assist in the implementation of similar clinics. We present this review of the patients, as a template for supporting the work of Paediatric Orthopaedic Departments. This service has facilitated the streamlining of our Consultant Paediatric Orthopaedic clinics.
Purpose of the study is to investigate the outcome of the patients with Perthes disease who have had a surgical dislocation of their hip for the treatment of resultant symptoms from the disease process. Retrospective review of consecutive patients treated with surgical dislocation of the hip for Perthes disease. Review of clinical case notes and radiological imaging. Patient outcome was assessed at follow-up. Between 2010 and 2015, 31 cases of surgical hip dislocation were performed for Perthes disease at our institution by 2 senior surgeons. Age range at time of surgery was 12–33. Male:female ratio was 13:18; right:left ratio was 15:17. Age at the time of Perthes diagnosis was between 3 and 13 years, with 3 diagnosed retrospectively. Mean follow-up was 18months. All patients had an EUA and arthrogram while 61.3%(19/31) had previous surgery for Perthes. 71%(22/31) required a labral repair, 6.5%(2/31) had a peri-acetabular osteotomy at the time of surgery and 3.2%(1/31) required a proximal femoral valgus osteotomy. 22.5%(7/31) required microfracture (femoral head or acetabulum): all of whom had evidence of contained area of degenerative changes on preoperative MRI. 64.5%(20/31) had the trochanteric screws removed. Complications included 1 greater trochanter non-union, 1 pain secondary to suture anchor impinging on psoas tendon, 1 AVN leading to early THR 12 months post-op. Another 2 had further deterioration of degenerative changes and pain leading to THR 18 and 24 months post-op. All 3(9.7%) had microfracture at the time of the dislocation for established degenerative change and also required custom made prostheses. Surgical hip dislocation is an option in treating Perthes patient with resultant symptoms such as impingement. Improved outcome is seen in patients who are younger with a congruent hip joint in contrast to those with established degenerative change evident on MRI / intraoperatively and have an arrow shaped femoral head.
This study aims to evaluate the development of deformity in patients with hypophosphataemic rickets and the evolution of the orthopaedic management thereof. Fifty-four patients had undergone treatment for hypophosphataemic rickets at our institution since 1995. Clinical records for all patients were obtained. Forty-one patients had long leg radiographs available that were analysed using Traumacad™ software. Statistical analysis was performed using SPSS 23 (SPSS Inc., Chicago, Illinois, USA). Of the 41 patients, 18 (43%) had no radiographic deformity. 20 have undergone bilateral lower limb surgery for persistent deformity (Mechanical Axis ≥ Zone 2). A further 3 patients are awaiting surgery. Six patients (12 limbs, 14 segments) had osteotomies and internal fixation as primary intervention: only one limb developed recurrent deformity. There were no major complications. Fourteen patients (28 limbs) had 8-plates (Orthofix, Verona) applied. In 5 limbs correction is on-going. Neutral alignment (central Zone 1) was achieved in 14/20 (70%) patients. Two patients required osteotomy and external fixation for resistant deformity. The mean rate of angular correction following 8-plate application was 0.3 and 0.7 degrees/month for the tibia and femur respectively. The mean age at 8-plate insertion was 10.25y (5–15y). Patients with more than 3 years of growth remaining responded significantly better than older patients (Fisher Exact Test, p=0.024). Guided growth was more successful in correcting valgus deformity than varus deformity (Fisher Exact Test, p=0.04). In the younger patients, diaphyseal deformity corrected as the mechanical axis improved at the rate of 0.2 and 0.7 degrees /month for the tibial and femoral shafts. Serum phosphate and alkaline phosphatase levels did not affect response to surgery or complication rate. Guided growth by means of 8-plates is a successful in addressing deformity in hypophosphataemic rickets. Surgery is best performed in patients with more than 3 years of growth remaining.
We present the 2 year results for the first 54 patients after Selective Dorsal Rhizotomy (SDR) delivered in Bristol, concentrating on change in Reimers' migration index. Eligible patients are selected at the SDR multidisciplinary meeting. Physiotherapy assessment is performed pre-operatively and at 6, 12 and 24 months post-surgery. Data collected includes GMFCS, Gross Motor Function Measure (GMFM) 88 and Modified Ashworth score for spasticity for major lower limb muscle groups, amongst other data. Pelvic radiographs are taken pre-operatively and at 2 years post-operatively. Reimers' migration index was measured using the hospital picture archiving and communication system (PACS). The mean age was 7.2 (3.9–17.5) at the time of surgery. Pre- and post-operative pelvic radiographs were available for 30 patients (60 hips). 57% (n=34) hips showed an increase in migration percentage (mean 5.4%, range 0.1–17.5%) and 43% (n=26) hips showed a decrease (mean 4.0%, range 0–15.5%). Overall no significant difference was found in Reimers' migration index at 2 year follow up (mean increase 1.3% (95% CI −0.3–3.0), p=0.12). There was an improvement in GMFCS category (by 1 grade) for 9 patients and a worsening for 1 patient at 2 year follow up. The Modified Ashworth score for spasticity improved in all patients. There was a mean improvement of 1.7 in the hip adductors and 2.4 in the ankle plantar flexors. There was a statistically significant improvement in the GMFM 88 D and E domains of 14.7 (95% CI 11.3–18.1), p<0.0001 and 11.4 (95% CI 7.4–15.7), p<0.0001 respectively. We found no evidence that SDR leads to worsening hip subluxation at 2 year follow up. All patients had improvement in lower limb spasticity. Overall there was a statistically significant improvement in function, as shown by GMFM 88 domains for standing, walking, running and jumping.
Our aim was to investigate the predictive factors for the development
of a rebound phenomenon after temporary hemiepiphysiodesis in children
with genu valgum. We studied 37 limbs with idiopathic genu valgum who were treated
with hemiepiphyseal stapling, and with more than six months remaining
growth at removal of the staples. All children were followed until
skeletal maturity or for more than two years after removal of the
staples.Aims
Patients and Methods
This study analysed the clinical and radiological outcome of
anatomical reduction of a moderate or severe stable slipped capital
femoral epiphysis (SCFE) treated by subcapital osteotomy (a modified
Dunn osteotomy) through the surgical approach described by Ganz. We prospectively studied 31 patients (32 hips; 16 females and
five males; mean age 14.3 years) with SCFE. On the Southwick classification,
ten were of moderate severity (head-shaft angle >
30° to 60°) and
22 were severe (head-shaft angle >
60°). Each underwent open reduction
and internal fixation using an intracapsular osteotomy through the
physeal growth plate after safe surgical hip dislocation. Unlike
the conventional procedure, 25 hips did not need an osteotomy of
the apophysis of the great trochanter and were managed using an
extended retinacular posterior flap. Aims
Patients and Methods
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, lumbar curvature or functional outcomes. We reviewed 42 children at more than ten years post-operatively
following a unilateral Salter osteotomy or Pemberton acetabuloplasty.
We measured the increase in pelvic height and the iliac crest tilt
and sacral tilt at the most recent review and at an earlier review
point in the first decade of follow-up. We measured the lumbar Cobb angle
and the Short Form-36 (SF-36) and Harris hip scores were collected
at the most recent review.Aims
Patients and Methods
To explore the of age of onset distribution for Perthes’ disease
of the hip, with particular reference to gender, laterality and
conformity to the lognormal distribution. A total of 1082 patients were identified from the Liverpool Perthes’
Disease Register between 1976 and 2010, of which 992 had the date
of diagnosis recorded. In total, 682 patients came from the geographical
area exclusively served by Alder Hey Hospital, of which 673 had
a date of diagnosis. Age of onset curves were analysed, with respect to
the predefined subgroups.Aims
Patients and Methods
Although atlantoaxial rotatory fixation (AARF) is a common cause
of torticollis in children, the diagnosis may be delayed. The condition
is characterised by a lack of rotation at the atlantoaxial joint
which becomes fixed in a rotated and subluxed position. The management of
children with a delayed presentation of this condition is controversial.
This is a retrospective study of a group of such children. Children who were admitted to two institutions between 1988 and
2014 with a diagnosis of AARF were included. We identified 12 children
(four boys, eight girls), with a mean age of 7.3 years (1.5 to 13.4),
in whom the duration of symptoms on presentation was at least four weeks
(four to 39). All were treated with halo traction followed by a
period of cervical immobilisation in a halo vest or a Minerva jacket.
We describe a simple modification to the halo traction that allows
the child to move their head whilst maintaining traction. The mean follow-up
was 59.6 weeks (24 to 156).Aims
Patients and Methods
There is increasing evidence that flexible flatfoot (FF) can
lead to symptoms and impairment in health-related quality of life.
As such we undertook an observational study investigating the aetiology
of this condition, to help inform management. The hypothesis was
that as well as increased body mass index (BMI) and increased flexibility of
the lower limb, an absent anterior subtalar articulation would be
associated with a flatter foot posture. A total of 84 children aged between eight and 15 years old were
prospectively recruited. The BMI for each child was calculated,
flexibility was assessed using the lower limb assessment scale (LLAS)
and foot posture was quantified using the arch height index (AHI).
Each child underwent a sagittal T1-weighted MRI scan of at least
one foot. Aims
Patients and Methods
The aims of this study were to describe the course of non-operatively
managed, bilateral Perthes’ disease, and to determine specific prognostic
factors for the radiographic and clinical outcome. We identified 40 children with a mean age of 5.9 years (1.8 to
13.5), who were managed non-operatively for bilateral Perthes’ disease
from our prospective, multicentre study of this condition, which
included all children in Norway who were diagnosed with Perthes’
disease in the five-year period between 1996 and 2000. All children
were followed up for five years. The hips were classified according to the Catterall classification.
A modified three-group Stulberg classification was used as an outcome
measure, with a spherical femoral head being defined as a good outcome,
an oval head as fair, and a flat femoral head as a poor outcome. Aims
Patients and Methods
Single event multilevel surgery (SEMLS) has been shown to improve
gait in children with cerebral palsy (CP). However, there is limited
evidence regarding long-term outcomes and factors influencing them. In total 39 children (17 females and 22 males; mean age at SEMLS
ten years four months, standard deviation 37 months) with bilateral
CP (20 Gross Motor Function Classification System (GMFCS) level
II and 19 GMFCS level III) treated with SEMLS were included. Children
were evaluated using gait analysis and the Gait Deviation Index
(GDI) before SEMLS and one, two to three, five and at least ten
years after SEMLS. A linear mixed model was used to estimate the
effect of age at the surgery, GMFCS and follow-up period on GDI. Aims
Methods
A retrospective study was performed in 100 children
aged between two and 16 years, with a dorsally angulated stable
fracture of the distal radius or forearm, who were treated with
manipulation in the emergency department (ED) using intranasal diamorphine
and 50% oxygen and nitrous oxide. Pre- and post-manipulation radiographs,
the final radiographs and the clinical notes were reviewed. A successful
reduction was achieved in 90 fractures (90%) and only three children
(3%) required remanipulation and Kirschner wire fixation or internal
fixation. The use of Entonox and intranasal diamorphine is safe and effective
for the closed reduction of a stable paediatric fracture of the
distal radius and forearm in the ED. By facilitating discharge on the same day, there is a substantial
cost benefit to families and the NHS and we recommend this method. Take home message: Simple easily reducible fractures of the distal
radius and forearm in children can be successfully and safely treated
in the ED using this approach, thus avoiding theatre admission and
costly hospital stay. Cite this article:
The aims of this study were to report functional
outcomes of salvage procedures for patients with cerebral palsy (CP)
who have chronic dislocation of the hip using validated scoring
systems, and to compare the results of three surgical techniques. We reviewed 37 patients retrospectively. The mean age at the
time of surgery was 12.2 years (8 to 22) and the mean follow-up
was 56 months (24 to 114). Patients were divided into three groups:
14 who underwent proximal femoral resection arthroplasty (PFRA group
1), ten who underwent subtrochanteric valgus osteotomy (SVO group 2),
and 13 who underwent subtrochanteric valgus osteotomy with resection
of the femoral head (SVO with FHR group 3). All patients were evaluated
using the Caregiver Priorities and Child Health Index of Life with
Disabilities (CPCHILD) and the Pediatric Quality of Life Inventory
(PedsQL). Significant improvements occurred in most CPCHILD and PedsQL
subsection scores following surgery in all patients, without significant
differences between the groups. There were 12 post-operative complications.
Less severe complications were seen in group 1 than in groups 2
and 3. Salvage surgery appears to provide pain relief in patients with
CP who have painful chronic dislocation of the hip. The three salvage
procedures produced similar results, however, we recommend the use
of PFRA as the complications are less severe. Take home message: Salvage surgery can be of benefit to patients
with CP with chronic painful hip dislocation, but should be limited
to selected patients considering complications. Cite this article:
Slipped upper femoral epiphysis (SUFE) is the
most common hip disorder to affect adolescents. Controversy exists over
the optimal treatment of severe slips, with a continuing debate
between Between 2001 and 2011, 57 patients (35 male, 22 female) with
a mean age of 13.1 years (9.6 to 20.3, SD 2.3) were referred to
our tertiary referral institution with a severe slip. The affected
limb was rested in slings and springs before corrective surgery
which was performed via an anterior Smith-Petersen approach. Radiographic
analysis confirmed an improvement in mean head–shaft slip angle
from 53.8o (standard deviation ( This is a technically demanding operation with variable outcomes
reported in the literature. We have demonstrated good results in
our tertiary centre. Cite this article:
The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated angular deformity and leg-length
discrepancy. Callus formation was slightly delayed because of periosteal
elevation and stretching during resection of the bar. The resultant
resection of the bar was satisfactory in seven patients and fair
in three as assessed using a by a modified Williamson–Staheli classification. Cite this article:
The accurate assessment of skeletal maturity
is essential in the management of orthopaedic conditions in the growing
child. In order to identify the time of peak height velocity (PHV)
in adolescents, two systems for assessing skeletal maturity have
been described recently; the calcaneal apophyseal ossification method
and the Sanders hand scores. The purpose of this study was to compare these methods in assessing
skeletal maturity relative to PHV. We studied the radiographs of
a historical group of 94 healthy children (49 females and 45 males),
who had been followed longitudinally between the ages of three and
18 years with serial radiographs and physical examination. Radiographs
of the foot and hand were undertaken in these children at least
annually between the ages of ten and 15 years. We reviewed 738 radiographs
of the foot and 694 radiographs of the hand. PHV was calculated
from measurements of height taken at the time of the radiographs. Prior to PHV we observed four of six stages of calcaneal apophyseal
ossification and two of eight Sanders stages. Calcaneal stage 3
and Sanders stage 2 was seen to occur about 0.9 years before PHV,
while calcaneal stage 4 and Sanders stage 3 occurred approximately
0.5 years after PHV. The stages of the calcaneal and Sanders systems can be used in
combination, offering better assessment of skeletal maturity with
respect to PHV than either system alone. Cite this article:
Developmental dysplasia of the hip (DDH) should
be diagnosed as early as possible to optimise treatment. The current
United Kingdom recommendations for the selective screening of DDH
include a clinical examination at birth and at six weeks. In Northern
Ireland babies continue to have an assessment by a health visitor
at four months of age. As we continue to see late presentations
of DDH, beyond one year of age, we hypothesised that a proportion had
missed an opportunity for earlier diagnosis. We expect those who
presented to our service with Tonnis grade III or IV hips and decreased
abduction would have had clinical signs at their earlier assessments. We performed a retrospective review of all patients born in Northern
Ireland between 2008 and 2010 who were diagnosed with DDH after
their first birthday. There were 75 856 live births during the study
period of whom 645 children were treated for DDH (8.5 per 1000).
The minimum follow-up of our cohort from birth, to detect late presentation,
was four years and six months. Of these, 32 children (33 hips) were
diagnosed after their first birthday (0.42 per 1000). With optimum application of our selective screening programme
21 (65.6%) of these children had the potential for an earlier diagnosis,
which would have reduced the incidence of late diagnosis to 0.14
per 1000. As we saw a peak in diagnosis between three and five months
our findings support the continuation of the four month health visitor
check. Our study adds further information to the debate regarding

A retrospective study was performed in 18 patients
with achondroplasia, who underwent bilateral humeral lengthening
between 2001 and 2013, using monorail external fixators. The mean
age was ten years (six to 15) and the mean follow-up was 40 months
(12 to 104). The mean disabilities of the arm, shoulder and hand (DASH) score
fell from 32.3 (20 to 40)
pre-operatively to 9.4 (6 to 14) post-operatively (p = 0.037). A
mean lengthening of 60% (40% to 95%) was required to reach the goal
of independent perineal hygiene. One patient developed early consolidation,
and fractures occurred in the regenerate bone of four humeri in
three patients. There were three transient radial nerve palsies. Humeral lengthening increases the independence of people with
achondroplasia and is not just a cosmetic procedure. Cite this article:
This retrospective study was designed to evaluate
the outcomes of re-dislocation of the radial head after corrective osteotomy
for chronic dislocation. A total of 12 children with a mean age
of 11 years (5 to 16), with further dislocation of the radial head
after corrective osteotomy of the forearm, were followed for a mean
of five years (2 to 10). Re-operations were performed for radial
head re-dislocation in six children, while the other six did not
undergo re-operation (‘non-re-operation group’). The active range
of movement (ROM) of their elbows was evaluated before and after
the first operation, and at the most recent follow-up. In the re-operation group, there were significant decreases in
extension, pronation, and supination when comparing the ROM following
the corrective osteotomy and following
re-operation (p <
0.05). The children who had not undergone re-operation achieved a better
ROM than those who had undergone re-operation. There was a significant difference in mean pronation (76° Cite this article:
Controversy remains whether the contralateral
hip should be fixed in patients presenting with unilateral slipped capital
femoral epiphysis (SCFE). This retrospective study compares the
outcomes and cost of those patients who had prophylactic fixation
with those who did not. Between January 2000 and December 2010 a total of 50 patients
underwent unilateral fixation and 36 had prophylactic fixation of
the contralateral hip. There were 54 males and 32 females with a
mean age of 12.3 years (9 to 16). The rate of a subsequent slip
without prophylactic fixation was 46%. The risk of complications
was greater, the generic health measures (Short Form-12 physical
(p <
0.001) and mental (p = 0.004) summary scores) were worse.
Radiographic cam lesions in patients presenting with unilateral
SCFE were only seen in patients who did not have prophylactic fixation.
Furthermore, prophylactic fixation of the contralateral hip was
found to be a cost-effective procedure, with a cost per quality
adjusted life year gained of £1431 at the time of last follow-up. Prophylactic fixation of the contralateral hip is a cost-effective
operation that limits the morbidity from the complications of a
further slip, and the diminished functional outcome associated with
unilateral fixation. Cite this article:
Pelvic obliquity is a common finding in adolescents
with cerebral palsy, however, there is little agreement on its measurement
or relationship with hip development at different gross motor function
classification system (GMFCS) levels. The purpose of this investigation was to study these issues in
a large, population-based cohort of adolescents with cerebral palsy
at transition into adult services. The cohort were a subset of a three year birth cohort (n = 98,
65M: 33F, with a mean age of 18.8 years (14.8 to 23.63) at their
last radiological review) with the common features of a migration
percentage greater than 30% and a history of adductor release surgery. Different radiological methods of measuring pelvic obliquity
were investigated in 40 patients and the angle between the acetabular
tear drops (ITDL) and the horizontal reference frame of the radiograph
was found to be reliable, with good face validity. This was selected
for further study in all 98 patients. The median pelvic obliquity was 4° (interquartile range 2° to
8°). There was a strong correlation between hip morphology and the
presence of pelvic obliquity (effect of ITDL on Sharpe’s angle in
the higher hip; rho 7.20 (5% confidence interval 5.59 to 8.81, p
<
0.001). This was particularly true in non-ambulant adolescents
(GMFCS IV and V) with severe pelvic obliquity, but was also easily
detectable and clinically relevant in ambulant adolescents with mild
pelvic obliquity. The identification of pelvic obliquity and its management deserves
closer scrutiny in children and adolescents with cerebral palsy. Cite this article:
Hip displacement, defined in this study as a
migration percentage (MP) of more than 40%, is a common, debilitating complication
of cerebral palsy (CP). In this prospective study we analysed the
risk of developing hip displacement within five years of the first
pelvic radiograph. All children with CP in southern and western Sweden are invited
to register in the hip surveillance programme CPUP. Inclusion criteria
for the two groups in this study were children from the CPUP database
born between 1994 and 2009 with Gross Motor Function Classification
System (GMFCS) III to V. Group 1 included children who developed
hip displacement, group 2 included children who did not develop
hip displacement over a minimum follow-up of five years. A total
of 145 children were included with a mean age at their initial pelvic
radiograph of 3.5 years (0.6 to 9.7). The odds ratio for hip displacement was calculated for GMFCS-level,
age and initial MP and head-shaft angle. A risk score was constructed
with these variables using multiple logistic regression analysis.
The predictive ability of the risk score was evaluated using the
area under the receiver operating characteristics curve (AUC). All variables had a significant effect on the risk of a MP >
40%. The discriminatory accuracy of the CPUP hip score is high (AUC
= 0.87), indicating a high ability to differentiate between high-
and low-risk individuals for hip displacement. The CPUP hip score
may be useful in deciding on further follow-up and treatment in
children with CP. Cite this article:
The recognition of hips at risk of displacement
in children with cerebral palsy (CP) is a difficult problem for
the orthopaedic surgeon. The Gross Motor Function Classification
System (GMFCS) and head–shaft angle (HSA) are prognostic factors
for hip displacement. However, reference values for HSA are lacking.
This study describes and compares the development of HSA in normal
hips and children with CP. We selected 33 children from a retrospective cohort with unilateral
developmental dysplasia of the hip (DDH) (five boys, 28 girls) and
50 children (35 boys, 15 girls) with CP with GMFCS levels II to
V. HSA of normal developing hips was measured at the contralateral
hip of unilateral DDH children (33 hips) and HSA of CP children
was measured in both hips (100 hips). Measurements were taken from
the radiographs of the children at age two, four and seven years.
The normal hip HSA decreased by 2° per year (p <
0.001). In children
with CP with GMFCS levels II and III HSA decreased by 0.6° (p =
0.046) and 0.9° (p = 0.049) per year, respectively. The HSA did
not alter significantly in GMFCS levels IV and V. Between the ages of two and eight years, the HSA decreases in
normal hips and CP children with GMFCS level, II to III but does
not change in GMFCS levels IV to V. As HSA has a prognostic value
for hip displacement, these reference values may help the orthopaedic
surgeon to predict future hip displacement in children with CP. Cite this article:
This study aimed to define the rates of lower limb angular correction using temporary hemiepiphysiodesis in differing skeletal pathologies. A retrospective review of 61 children (36M:25F) with angular deformities about the knee who underwent 8-plate hemiepiphysiodesis (mean age 10.8y) was undertaken. The children were divided into 9 groups based on their underlying pathology (lower limb hypoplasia, Blount's disease, skeletal dysplasia, rickets, metabolic disease, acquired growth disturbance, vascular malformation, steroid use and complex genetic disorders). Radiographic measurements of each limb segment was undertaken using the TraumaCad® digital templating software based on standing long-leg radiographs - mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA). The rate of correction of each parameter was calculated as a function of the time lapse between the operation date and first radiographic evidence of full correction of the mechanical axis (zone 1). A total of 144 limb segments (80 distal femoral, 64 proximal tibial physes) were analysed. 62.5% of children had mechanical axes outside the knee joint at the time of operation; 63.2% achieved full correction. The rate of angular correction at the distal femur (mLDFA) was quickest in those with acquired growth disturbance (1.15°/month), complex genetic disorders (1.12°/month) and rickets (0.93°/month). It was slowest in those with vascular malformation (0.40°/month), lower extremity hypoplasia (0.44°/month) and metabolic disease (0.49°/month). At the proximal tibia, mMPTA correction was quickest in those with acquired growth disturbance (0.77°/month) and skeletal dysplasia (0.57°/month); whilst being slowest in those with metabolic disease (0.22°/month) and Blount's disease (0.29°/month). The rate of angular correction about the knee varies with the underlying pathology with correction rates varying up to 3-fold. This study demonstrated the differential rate of correction of angular deformities in children with different skeletal pathologies, which would help guide the timing of hemiepiphysiodesis.
A goal attainment scale (GAS) was used to evaluate outcomes of surgical and non-surgical interventions to improve gait in children with diplegic cerebral palsy (CP). Personal goals were recorded pre-intervention from children and/or their carers attending the Edinburgh Gait Laboratory since 2012. Twenty children underwent orthopaedic surgery (Group 1) and 25 children underwent a non-orthopaedic intervention (Group 2). Patients were excluded if the intervention was <9 months before the study period. Post-operatively children and/or their carers were contacted by telephone to complete the mGAS questionnaire, rating the achievement of goals on a 5-point scale. The majority of goals related to structure and function and were similar between groups, with goals relating to stability and lower limb structure most frequently recorded. Attaining an improvement in pain was stated more frequently by Group 1 children. The GAS formula was used to transform the composite GAS into a standardised measure (T-score) for each patient. A t-test was used to determine if the change in T-score was significantly different from 0, i.e. no change. Both groups on average achieved their goals (mean change in T-score for Group 2 11.1, vs 21.1 for Group 1). The difference between these two means was significant (p = 0.012). Additionally 16 children had undergone a follow-up gait analysis, but the relationship between the change in Gait Profile Score and GAS, assessed by Pearson's correlation coefficient was statistically insignificant. Both surgical and non-surgical interventions enabled children to achieve their goals, although Group 1 reported higher achievement. GAS reflect patients’ aspirations and may be as relevant as post-intervention kinematic or kinetic outcomes.
Paediatric distal radial and forearm fractures account for 37.4% of all fractures in children. We present our 2.5-year results of a novel safe approach to the treatment of simple distal radial and diaphyseal fractures using intranasal diamorphine and entonox in a designated fracture reduction room in the emergency department. All simple fractures of the distal radius and forearm admitted to our ED between March 2012 and August 2014 that could be reduced using simple manipulation techniques were included in this study. These included angulated diaphyseal fractures of the forearm, angulated metaphyseal fractures of the distal radius and Salter Harris types I and II without significant shortening. All children included were given intranasal diamorphine as well as entonox. The orthopaedic registrar on call performed all reductions. 100 children had their distal radius or forearm fracture reduced in the emergency department using entonox and diamorphine analgesia and had a same day discharge. Average age was 10 years (range 2.20–16.37 years). No complications were reported regarding the use of the analgesia and all children and parents were pleased with their treatment not requiring a hospital admission. The mean initial dorsal angulation of all fracture types was 28.05° degrees (23.91–32.23 95% CI) which was reduced to 7.03° (5.11–8.95 95% CI) post manipulation. There were 9 cases lost to follow up. Two cases lost the initial reduction of the fracture on subsequent clinic follow up and underwent internal fixation in theatre. The use of entonox and intranasal diamorphine is a safe, effective treatment of providing adequate analgesia for children with distal radial and forearm fractures to allow manipulation of displaced dorsally angulated fractures in the emergency department. By facilitating a same day discharge, over £45,000 was saved using this safe method of treatment.
The aim was to assess the long-term impact of humeral and forearm rodding on functional ability, grip strength, joint range of motion and angular deformity in children with osteogenesis imperfecta. A retrospective chart review was conducted on 57 children with osteogenesis imperfecta who underwent humeral rodding or forearm rodding at our institution between 1996 and 2013. Functional ability was assessed using the self-care and mobility domains of the Pediatric Evaluation and Disability Inventory (PEDI). Grip strength was measured using a dynamometer and joint range of motion with a goniometer. Deformity was measured on radiographs of the humerus or forearm. Outcomes were assessed pre-operatively and every year post-operatively. Differences between pre-operative and 1-year post-operative outcomes were compared using paired T-tests. In 44 patients with a minimum of 2 years follow-up, outcome measures at 1-year post-surgery were compared to those at the latest clinic visit (mean follow-up = 8.0 years). Humeral and forearm rodding resulted in a significant improvement in PEDI self-care score (mean change =5.75, p=0.028 for the humerus, mean change = 6.77, p=0.0017 for the forearm) and mobility score (mean change =3.59, p=0.008 for the humerus, mean change =7.21, p=0.020 for the forearm) at 1 year post-surgery. Grip strength improved following forearm rodding (mean change = +6.13N, p=0.015) but not humeral rodding. Joint range of movement improved following humeral rodding but not forearm rodding. There was a significant improvement in radiographic angular deformity of the forearm and humerus following surgery (p<0.0001). Over 80% of improvements were maintained in the long-term. Humeral and forearm rodding in children with osteogenesis imperfecta leads to long-term improvement in functional ability and angular deformity.
The aim was to assess the effect of caudal block on patients who have had proximal femoral &/or pelvic osteotomy compared to patients who have had epidural anaesthesia with regards to pain relief and hospital stay. We looked at two patient cohorts; epidural & caudal pain relief in aforementioned procedures. Interrogation of our clinical database (WinDip, BlueSpeir&clinical notes) identified 57 patients: 33 proximal femoral osteotomy, 13 pelvic osteotomy and 11 combined(25 Males 32 Females), aged 1–18 years-old between 2012–2014, in two institutions. A database of demographics, operative indications, associated procedures, analgesia and type of anaesthesia was constructed in relation to daily pain score and length of hospital stay. 39 patients had epidural anaesthesia, and 18 had caudal block. Cerebral palsy with unstable hips was the commonest indication(21), followed by dysplastic hip(10), Perthes disease(8) and other causes(18). The Face, Legs, Activity, Cry, Consolability(FLACC) scale was used to assess pain. Length of hospital stay in caudal block patients was 3.1 days(1–9), in epidural anaesthesia patients stay was 4.46 days(2–13). Paediatrics high dependency unit after an epidural was needed in 20(Average stay 3.4 days) compared to 1 who received caudal block. Caudal block FLACC pain score in the first 36 hours was 1.23(0–4) compared to 0.18(0–2) in patients who had an epidural. Caudal block is associated with less hospital stay and fewer admissions to the high dependency unit, it also provides adequate pain relief post osteotomies when compared to epidural, therefore could be performed at units lacking epidural facilities. A change in related practice however should be cautious and supported by further studies.
