Most centres in the United Kingdom adopt a selective
screening programme for developmental dysplasia of the hip (DDH)
based on repeated clinical examination and selective ultrasound
examination. The Newborn Infant Physical Examination protocol implemented
in 2008 recommends a first examination at birth and then a second
and final examination at six to ten weeks of age. Due to concerns
over an increase in late presentations we performed a retrospective
review of our 15-year results to establish if late presentation
increases treatment requirements. Of children presenting before
six weeks of age, 84% were treated successfully with abduction bracing,
whereas 86% of children presenting after ten months eventually required
open reduction surgery. This equates to a 12-fold increase in relative
risk of requiring open reduction following late presentation. Increasing
age at presentation was associated with an increase in the number
of surgical procedures, which are inevitably more extensive and complex,
with a consequent increased in cost per patient. The implementation
of an opportunistic examination at three to five months could help
to reduce the unintended consequences of the Newborn Infant Physical Examination
programme. Cite this article:
The aim of this study was to review the value of accepting referrals for children with ‘clicky hips’ in a selective screening programme for hip dysplasia. A single-centre prospective database of all referrals to the hip clinic was examined to identify indication for referrals, diagnosis, and treatment. All patients referred received a standardized ultrasound scan and clinical examination by an orthopaedic consultant.Aims
Patients and Methods
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
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
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
To monitor the performance of services for developmental dysplasia of the hip (DDH) in Northern Ireland and identify potential improvements to enhance quality of service and plan for the future. This was a prospective observational study, involving all infants treated for DDH between 2011 and 2017. Children underwent clinical assessment and radiological investigation as per the regional surveillance policy. The regional radiology data was interrogated to quantify the use of ultrasound and ionizing radiation for this population.Aims
Methods
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
Patients and Methods
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
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
Patients and Methods
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

Over a 15-year prospective period, 201 infants
with a clinically unstable hip at neonatal screening were subsequently
reviewed in a ‘one stop’ clinic where they were assessed clinically
and sonographically. Their mean age was 1.62 weeks (95% confidence
interval (CI) 1.35 to 1.89). Clinical neonatal hip screening revealed
a sensitivity of 62% (mean, 62.6 95%CI 50.9 to 74.3), specificity
of 99.8% (mean, 99.8, 95% CI 99.7 to 99.8) and positive predictive value
(PPV) of 24% (mean, 26.2, 95% CI 19.3 to 33.0). Static and dynamic
sonography for Graf type IV dysplastic hips had a 15-year sensitivity
of 77% (mean, 75.8 95% CI 66.9 to 84.6), specificity of 99.8% (mean,
99.8, 95% CI 99.8 to 99.8) and a PPV of 49% (mean, 55.1, 95% CI
41.6 to 68.5). There were 36 infants with an irreducible dislocation
of the hip (0.57 per 1000 live births), including six that failed
to resolve with neonatal splintage. Most clinically unstable hips referred to a specialist clinic
are female and stabilise spontaneously. Most irreducible dislocations
are not identified from this neonatal instability group. There may
be a small subgroup of females with instability of the hip which
may be at risk of progression to irreducibility despite early treatment
in a Pavlik harness. A controlled study is required to assess the value of neonatal
clinical screening programmes. Cite this article:
