Abstract
PURPOSE The aim of our study was to use the chondro-osseous border (COB) as an indispensable assessment criterion to evaluate the quality of baby hip ultrasonography (US) images in the literature pertaining to the application of Graf's technique. MATERIALS AND METHODS Our literature review search yielded 144 articles. Of these, 41 contained images that were stated to be based on the application of Graf's technique. Two reviewers, a radiologist and an orthopaedic surgeon, both course instructors for the use of baby hip US for developmental dysplasia of the hip (DDH), independently evaluated the articles to assess the diagnostic validity of the published images on the basis of a single criterion: the identification of the COB. RESULTS Of the 41 articles which were analyzed, 15 contained images without a COB, which corresponds to 36% (roughly, one out of three). Articles from countries where universal screening is performed (Germany, Italy, Switzerland, Mongolia) were all correct. All the articles from Turkey, a country which has made significant contribution with published material about Graf's technique over many years, and most of the articles from China (80%), where Graf's technique has become popular in recent years, contained correct images. CONCLUSION Published literature lacks strict criteria for the publication of correct images corresponding to Graf's technique in baby hip US. This fact raises concerns about the quality of published material (and, as a corollary, the quality of clinical application of the technique) and should have ramifications on scientific journal policies regarding the publication of such manuscripts.

Abstract
BACKGROUND DDH is 1 of the most important causes of childhood disability. A diagnosis of instability can be made in the neonatal period via the Ortolani and Barlow manoeuvres. However, clinical examination, although highly specific, has poor sensitivity as compared to ultrasound. There is controversy between the necessity of universal screening for dysplasia of all newborns or selective screening reserved for those with clinical signs of instability or known risk factors of DDH. AIM To analyse the risk factors of congenital hip dysplasia in a consecutive case series of children referred for diagnosis and treatment of DDH. MATERIALS AND METHODS This was a cross-sectional study on infants consecutively examined between January 2000 and December 2019 at the Marino Ortolani Centre in Ferrara, Italy. The first 3 types on Graf's classification were considered physiological (1A, 1B, 2A+), while the last 6 pathological (2A-, 2B, 2C, 2D, 3, 4). RESULTS 18,954 infants met the inclusion criteria and were therefore considered eligible for the study. Of these 18,954 infants, 56% (n = 10,629) were females and 44% (n = 8325) were males. According to Graf classification, 34.9% (n = 6621) were 1A, 52.7% (n = 9999) were 1B, 4.0% (n = 753) were 2A+, 2.5% (n = 478) were 2A-, 1.5% (n = 284) were 2B, 1% (n = 196) were 2C, 1.3% (n = 243) were 2D, 1% (n = 193) were 3 and 1.0% (n = 187) were 4. The most significant risk factor was the female gender (OR 5.36; 95% CI, 4.63-6.20) followed by a family history (OR 2.35; 95% CI, 2.08-2.65), then skeletal pathologies (OR 2.04; 95% CI, 1.21-3.42), oligohydramnios (OR 1.75; 95% CI, 1.44-2.13), and finally breech presentation (OR 1.42: 95% CI, 1.27-1.60). CONCLUSIONS Based on our data, family history, musculoskeletal disease, oligohydramnios and breech presentation are the main risk factors for DDH development, as is the female sex.

Abstract
Importance Delayed diagnosis of a dislocated hip in infants can lead to complex childhood surgery, interruption to family life, and premature osteoarthritis. Objective To evaluate the diagnostic accuracy of clinical examination in identifying dislocated hips in infants. Data Sources Systematic search of CINAHL, Embase, MEDLINE, and the Cochrane Library from the inception of each database until October 31, 2023. Study Selection The 9 included studies reported the diagnostic accuracy of the clinical examination (index test) in infants aged 3 months or younger and a diagnostic hip ultrasound (reference test). The Graf method of ultrasound assessment was used to classify hip abnormalities. Data Extraction and Synthesis The Rational Clinical Examination scale was used to assign levels of evidence and the Quality Assessment of Diagnostic Accuracy Studies tool was used to assess bias. Data were extracted using the individual hip as the unit of analysis; the data were pooled when the clinical examinations were evaluated by 3 or more of the included studies. Main Outcomes and Measures Sensitivity, specificity, and likelihood ratios (LRs) of identifying a dislocated hip were calculated. Results Among infants screened with a clinical examination and a diagnostic ultrasound in 5 studies, the prevalence of a dislocated hip (n = 37 859 hips) was 0.94% (95% CI, 0.28%-2.0%). There were 8 studies (n = 44 827 hips) that evaluated use of the Barlow maneuver and the Ortolani maneuver (dislocate and relocate an unstable hip); the maneuvers had a sensitivity of 46% (95% CI, 26%-67%), a specificity of 99.1% (95% CI, 97.9%-99.6%), a positive LR of 52 (95% CI, 21-127), and a negative LR of 0.55 (95% CI, 0.37-0.82). There were 3 studies (n = 22 472 hips) that evaluated limited hip abduction and had a sensitivity of 13% (95% CI, 3.3%-37%), a specificity of 97% (95% CI, 87%-99%), a positive LR of 3.6 (95% CI, 0.72-18), and a negative LR of 0.91 (95% CI, 0.76-1.1). One study (n = 13 096 hips) evaluated a clicking sound and had a sensitivity of 13% (95% CI, 6.4%-21%), a specificity of 92% (95% CI, 92%-93%), a positive LR of 1.6 (95% CI, 0.91-2.8), and a negative LR of 0.95 (95% CI, 0.88-1.0). Conclusions and Relevance In studies in which all infant hips were screened for developmental dysplasia of the hip, the prevalence of a dislocated hip was 0.94%. A positive LR for the Barlow and Ortolani maneuvers was the finding most associated with an increased likelihood of a dislocated hip. Limited hip abduction or a clicking sound had no clear diagnostic utility.

Comparison of quality and interpretation of newborn ultrasound screening examinations for developmental dysplasia of the hip by basically trained nurses and junior physicians with no previous ultrasound experience. PLoS One 2024; 19:e0300753.

Abstract
BACKGROUND We are obliged to give babies the chance to profit from a nationwide screening of developmental dysplasia of the hip in very rural areas of Mongolia, where trained physicians are scarce. This study aimed to compare the quality and interpretation of hip ultrasound screening examinations performed by nurses and junior physicians. METHODS A group of 6 nurses and 6 junior physician volunteers with no previous ultrasound experience underwent Graf's standard training in hands-on practice. Newborns were examined before discharge from the hospital, according to the national guideline. Two standard documentation images of each hip were saved digitally. The groups were compared on the proportion of good quality of sonograms and correct interpretation. Two Swiss supervisors' agreed diagnosis according to Graf was considered the final reference for the study purposes. RESULTS A total of 201 newborns (402 hips or 804 sonograms) were examined in the study, with a mean age of 1.3±0.8 days at examination. Junior physicians examined 100 newborns (200 hips or 400 sonograms), while nurses examined 101 newborns (202 hips or 404 sonograms). The study subjects of the two groups were well balanced for the distribution of baseline characteristics. The study observed no statistically significant difference in the quality of Graf's standard plane images between the providers. Eventually, 92.0% (92) of the physician group and 89.1% (90) of the nurse group were correctly diagnosed as "Group A" (Graf's Type 1 hip) or "Non-Group A" hips (p = 0.484). The most common errors among the groups were a missing lower limb, wrong measurement lines, and technical problems. CONCLUSION Our study provides evidence that while there might be a trend of slightly more technical mistakes in the nurse group, the overall diagnosis accuracy is similar to junior physicians after receiving standard training in Graf's hip ultrasound method. However, after basic training, regular quality control is a must and all participants should receive refresher trainings. More specifically, nurses need training in the identification of anatomical structures.

Abstract
Until the 1980s, the diagnosis of developmental dysplasia of the hip (DDH) was based on clinical examination and radiographic imaging. In 1980, Reinhard Graf developed his own ultrasonographic method for the examination of the infant hip joint. Graf's method evaluates the osseous and cartilaginous coverage of the femoral head by the acetabulum in the infantile hip joint by measuring the angles α and β. The validity of Graf method is that with these measurements the hip joint is further classified by Graf classification into types I to IV that guide treatment. Currently, Graf method is considered the gold standard examination for the diagnosis of DDH in many European countries. This review article aims to discuss the incidence, risk factors and pathophysiology of DDH, and to emphasize on the Graf method for the evaluation, classification, prevention and further management of this entity.

Abstract
Objectives The ultrasound examination of the hip joint is performed in the static (Graf) technique in the lateral recumbent position and in the dynamic technique in the supine position. This study compares the two static and dynamic techniques and assesses the role of the patient's position in the examination of DDH. Methods This cross-sectional study was conducted in 2020-2021 at Akbar Hospital, Mashhad University of Medical Sciences, Iran. 126 patients suspected of having DDH (199 hip) infants were enrolled in the study. All ultrasound examinations were performed with two static and dynamic techniques by a pediatric radiologist. Results In the static and dynamic ultrasound examinations, the average alpha angle was 51.57 ± 6.41 degrees, and 53.41 ± 6.94 degrees, respectively. These changes were not statistically significant (P = 0.312). The relationship and agreement between instability with dynamic technique and instability with static technique (IIC unstable, D, III, and IV) were investigated. Significant agreement (Kappa=0.77 (95% CI: 0.66-0.87) with excellent clinical significance was obtained between the two ultrasound examination method. Also, in terms of DDH types in the static method with instability types in the dynamic method, a substantial agreement was found between the two examination methods (Kappa =0.67; (95% CI: 0.59-0.75) with good clinical significance. Conclusion In the ultrasound examination of DDH with static and dynamic techniques, the change in the alpha angle was not statistically significant. Therefore, the hand of the radiologist is open in measuring alpha angles and there is no need to emphasize a specific position. The type of DDH in the static technique completely corresponded to the type of stability or instability in the dynamic technique.

Abstract
BACKGROUND Hip dysplasia is one of the most common malformations in childhood and has a significant impact on the further life of those affected. A distinction must be made between congenital and the much rarer acquired dysplasia. Early diagnosis and therapy are pivotal for further development of patients. OBJECTIVES The paper gives an overview of current radiological possibilities of diagnosis with focus on congenital hip dysplasia supplemented by insights into therapeutic options. MATERIALS AND METHODS Basic and review papers were analyzed. RESULTS Clinical examination of the newborn has low sensitivity and specificity in the diagnosis of hip dysplasia. The introduction of Graf ultrasound screening has significantly improved the early detection of dysplastic hips. With the help of sonography, but also magnetic resonance imaging (MRI), the shape of the acetabulum and the position of the femoral head in the socket can be precisely and quickly determined, while X‑ray examinations have their place especially in the context of follow-up examinations after treatment from the age of 1 year and in the diagnosis of secondary dysplasia. Therapeutic options range from spreading treatment to open reduction with fixation in the newborn as well as conversion osteotomy in older children. CONCLUSION Early detection of hip dysplasia is critical to the course of treatment. The right choice of examination method and correct performance are essential for further treatment.

Abstract
Developmental dysplasia of the hip (DDH) is a condition that includes a wide spectrum of anomalies ranging from simple instability with ligamentous hyperlaxity to the complete displacement of the femoral head outside the abnormally developed cotyloid cavity. Early detection and initiation of treatment allow "restitutio ad integrum" healing, which has raised the medical community's interest in early diagnosis. However, in countries with limited material resources, where echographic screening is not performed, efforts are being made to increase the sensitivity of clinical screening. Thus, the concept of "hip at risk" is taking shape worldwide. This is the normal clinical hip, but associated with one or more risk factors. We conducted a retrospective study for the period 2010-2015 with patients who presented in the ambulatory clinic of the St. John Children's Clinical Hospital, Galati. The study included 560 patients, who were all examined clinically and sonographically, according to the Graf method, by a senior orthopedic doctor with competence in hip sonography. The data obtained from the anamnesis, clinical examination, and ultrasound examination were recorded in the DDH file. The goal of the statistical analysis of the group of patients was to find a correlation between DDH and the risk factors used in the clinical detection of this pathology. In the studied group, four risk factors were identified that have an increased association with DDH: female sex, pelvic presentation, limitation of coxo-femoral abduction, and congenital clubfoot; thus, the conclusion of the study is that patients who have at least one of the listed risk factors should be examined sonographically as quickly as possible. The early ultrasound examination will allow the identification of the disease and the initiation of treatment.

Abstract
Background & objectives Developmental dysplasia of the hip (DDH), when detected early, can usually be managed effectively by simple methods. A delayed diagnosis often makes it a complex condition to treat. Late presentation of DDH is fairly common in developing countries, and there is scarcity of literature regarding the epidemiology and reason for late presentation. Through this study, we attempted to identify the reasons for late presentation of DDH in children more than 12 months of age. Methods Fifty four children with typical DDH and frank dislocation of hip in whom treatment was delayed for 12 months or more were included. Parents were interviewed with a pre-structured questionnaire and data were collected for analysis with Microsoft Excel 2016 and SPSS version 26. Results Diagnostic delay was the most common reason for late presentation and was observed in 52 children (96.2%). The mean age at diagnosis was 24.7 months. The mean age at treatment was 37.3 months with a mean delay of 12.5 months from diagnosis and 22.1 months from initial suspicion. Physician-related factors contributed 55.3 per cent, while family and social issues accounted for 44.7 per cent of overall reasons for diagnostic and treatment delays. Interpretation & conclusions Late presentation of DDH in walking age is common. Physician- and family-related factors accounted for most of these cases. Failure or inadequate hip screening at birth by the attending physician is a common reason for late diagnosis. The family members were unaware about the disorder and developed suspicion once child started walking with an abnormal gait.

Abstract
There are concerns that selective sonographic screening for developmental dysplasia of the hip (DDH) may be suboptimal. Our aim was to test this hypothesis by identifying trends in presentation and surgical treatment in patients with DDH. This is a retrospective review of children born between 1997-2018 who were treated surgically for DDH at our sub- regional paediatric orthopaedic unit. Demographic data, risk factors, age of diagnosis and surgical treatments were analysed. Late diagnosis was defined as greater than 4 months. 103 children (14 male, 89 female) underwent surgery. 93 hips were operated for dislocation and 21 for dysplasia. 13 patients presented with bilateral hip dislocations. The median age at diagnosis was 10 months (95% CI: 4-15). 62/103 (60.2%) were diagnosed late (after 4 months) and the median age for diagnosis in this group was 18.5 months (95% CI: 16-20.5). Significantly more patients were referred late (p=0.0077). The presence of risk factors (breech presentation or family history) was associated with early diagnosis. Over the duration of our study the operation rate per 1000 live births gradually increased, and on Poisson regression analysis there was a statistically significant increasing trend towards late diagnosis in recent years (p=0.0237), which necessitated more aggressive surgical management. In the UK, the current selective sonographic screening programme for DDH has shown a deterioration over the years of this study and this questions its current effectiveness. It appears that the majority of irreducible hip dislocations are diagnosed late, with an increased need for surgical management.

Abstract
BACKGROUND A new, supposedly more reproducible radiographic classification, set to replace the Tönnis classification of hip dislocations, was proposed in 2015: the International Hip Dysplasia Institute (IHDI) classification. PURPOSE To compare the IHDI classification with the Tönnis classification when evaluating the severity of hip dislocations as well as their respective inter- and intra-observer reliability. MATERIAL AND METHODS Since January 2000, Swedish-born children with a hip dislocation were prospectively registered. From this registry, radiographs of 97 hips in 79 patients (91% girls; median age = 7 months), born in 2000-2009, were analyzed. Two observers, one consultant and one resident, classified each hip both by IHDI and Tönnis twice. RESULTS The IHDI classification had a more even distribution of grades with the majority in grade 2-3. The Tönnis classification graded the majority (77%) of the patients as grade 2 and equally among the other grades. There was moderate inter-observer agreement using both methods calculated with Kappa, 0.61 (95% confidence interval [CI] = 0.44-0.79) for Tönnis and 0.62 (95% CI = 0.49-0.74) for IHDI. The resident calculated Tönnis with weak intra-observer reliability of 0.57 (95% CI = 0.40-0.74) compared to high intra-observer reliability of 0.86 (95% CI = 0.74-0.98) for the consultant. Both observers graded IHDI with high intra-observer reliability. CONCLUSION IHDI is more discriminative than the Tönnis classification when evaluating the severity of a hip dislocation in infants.

Abstract
AIMS A national screening programme has existed in the UK for the diagnosis of developmental dysplasia of the hip (DDH) since 1969. However, every aspect of screening and treatment remains controversial. Screening programmes throughout the world vary enormously, and in the UK there is significant variation in screening practice and treatment pathways. We report the results of an attempt by the British Society for Children's Orthopaedic Surgery (BSCOS) to identify a nationwide consensus for the management of DDH in order to unify treatment and suggest an approach for screening. METHODS A Delphi consensus study was performed among the membership of BSCOS. Statements were generated by a steering group regarding aspects of the management of DDH in children aged under three months, namely screening and surveillance (15 questions), the technique of ultrasound scanning (eight questions), the initiation of treatment (19 questions), care during treatment with a splint (ten questions), and on quality, governance, and research (eight questions). A two-round Delphi process was used and a consensus document was produced at the final meeting of the steering group. RESULTS A total of 60 statements were graded by 128 clinicians in the first round and 132 in the second round. Consensus was reached on 30 out of 60 statements in the first round and an additional 12 in the seond. This was summarized in a consensus statement and distilled into a flowchart to guide clinical practice. CONCLUSION We identified agreement in an area of medicine that has a long history of controversy and varied practice. None of the areas of consensus are based on high-quality evidence. This document is thus a framework to guide clinical practice and on which high-quality clinical trials can be developed.Cite this article: Bone Joint J 2023;105-B(2):209-214.

Abstract
Purpose: This study aimed to determine whether point-of-care ultrasound performed during the Pavlik method treatment of developmental dysplasia of the hip predicts acetabular morphology at 12 months of age. Methods: We reviewed the medical records, ultrasounds, and radiographs of patients treated successfully with the Pavlik method between 2017 and 2019. We performed sonographic measurements on point-of-care ultrasound at the initial presentation, the Pavlik discontinuation, and an additional sonographic follow-up. We measured the acetabular index on a plain anteroposterior radiograph of the pelvis obtained at a minimum of 12 months of age. Spearman’s rank correlation coefficient was used to analyze for correlation between sonographic measurements and the acetabular index. Results: A total of 72 patients were included in the final analysis. There were no residual or late dysplasia cases at the last radiographic follow-up (mean age = 14.8 ± 2.7 months). Sonographic parameters at the initial presentation significantly correlated with the acetabular index at the final radiographic follow-up (p < 0.001). Patients with worsening degrees of developmental dysplasia of the hip based on stability on sonographic testing (stable, unstable, or dislocated) had higher acetabular indices at the final radiographic follow-up (p < 0.05). Conclusion: Point-of-care ultrasound at initial presentation and the Pavlik discontinuation significantly correlate with acetabular morphology at 1–1.5 years of age. At initial presentation, hips that were unstable or dislocated on point-of-care ultrasound had significantly greater acetabular indices than stable hips at the final follow-up. Level of evidence: level IV case series.

Abstract
Background/Aim: Hip ultrasonography (USG) is the most important diagnostic method in developmental hip dysplasia in newborns. However, a disadvantage of the ultrasonography method is that there can be measurement differences among doctors measuring the same hip. We aimed to investigate the causes and solutions of this situation. We further strived to measure the hip ultrasonography performed by different physicians using the Graf method and comparing the obtained values.
Methods: Hip USGs of newborns admitted to Malatya Turgut Ozal University Faculty of Medicine Hospital between Jan. 8, 2020 and Jan. 5,.2021 were measured and classified using the Graf method. The study type is consistent with retrospective cohort studies. Newborns aged 0-22 weeks without any additional pathology were included in the study. A radiologist and two orthopedists measured and interpreted the images separately in accordance with the Graf method. The first hip measurements (R1) were made by the radiologist (R) with the USG device, and they were classified according to alpha and beta angles; two printouts were made. The first orthopedic specialist (OS1) and the second orthopedic specialist (OS2) made their measurements with printouts. Subsequently, the results from the physicians were compared.
Results: A statistically significant difference was found between R1-OS2 (P < 0.001) and OS1-OS2 (P < 0.001) in terms of the Graf classifications. No statistically significant difference was found between R1 and OS1 in terms of the Graf classification (P = 0.562). A statistically significant difference was found between R1-OS2 (P < 0.001) and OS1-OS2 (P = 0.048) angles (alpha and beta) measurements. While R1 and OS1 measurements were compatible with each other, OS2 measurements were found to be inconsistent.
Conclusion: We think that there may be differences in angle measurements and the Graf classification among physicians who perform hip ultrasonography in newborns, and the most important way to correct this is through regular participation of physicians in subject-specific trainings.

Abstract
Developmental dysplasia of the hip (DDH) is the most common congenital disease of the musculoskeletal system in newborns and encompasses a disease spectrum ranging from a stable hip with a mildly dysplastic acetabulum to complete hip dislocation. Systematic screening for infant DDH has been performed for several decades all over the world and has contributed greatly to the early detection, diagnosis and treatment of DDH. However, some cases of delayed diagnosis still occur among the screened population, or conversely, overdiagnosis or overtreatment occasionally occurs. Furthermore, screening strategies for DDH are still controversial. The aim of our study was to analyze the current literature on DDH screening, paying particular attention to DDH screening strategies and their effectiveness. We searched the DDH screening literature from 1958 to 2021 in MEDLINE and other databases using PubMed. In this study, we reviewed the history of DDH screening and the progress of screening strategies and discussed the controversies regarding clinical and ultrasound screening methods with particular emphasis on the current opinions. Given the existing scientific evidence and changes in newborn DDH screening practices, universal ultrasound screening seems to be the best option for preventing late-detected cases and can be recommended as a favorable prevention strategy.

Abstract
BackgroundHip ultrasound screening for DDH provides better sensitivity compared to physical examination. Due to a lower prevalence and limited resources, selective hip ultrasound in newborns at risk could be considered a proper screening protocol in Thailand and Asian countries.ObjectiveThis study was aimed to evaluate risk factors and define criteria for selective screening.MethodsA case-control study was conducted in 2020. All newborns with hip ultrasound screening were included. Cases were defined as newborns with abnormal hip ultrasounds, while controls were those with normal studies. Inter and intra-rater reliability were evaluated. All factors were analyzed using univariate and multivariate logistic regression. The model performance was tested by Hosmer-Lemeshow goodness of fit. Internal validity was performed by the split data method. Area under the receiver operating characteristic (ROC) curve was estimated.ResultsNinety-five newborns (29 cases and 66 controls) were included. Eighty percent of cases and 58% of controls were female. The gestational age was 36.6 and 37.7 weeks in case and control, respectively. Female, breech presentation, positive Ortolani test, positive Barlow test, and limited hip abduction were significant factors with odds ratio of 2.82, 5.12, 34.21, 69.64, and 5.48, respectively. The final model included breech presentation, positive Ortolani test, and positive Barlow test. The model cut-off value 15.02 provided sensitivity (93.10%) and specificity were (80.30%). The area under the ROC curve was 0.9308. The split data remained significant internal validity for all factors with p-value < 0.05.ConclusionCareful history taking and physical examination are essential to identify the risk factors for DDH. Newborns with breech presentation, positive Ortolani test and positive Barlow test should be screened by hip ultrasound.

Abstract
IMPORTANCE Universal ultrasonographic screening for developmental dysplasia of the hip (DDH) has gained increasing popularity despite the lack of benefit in terms of reducing the rates of late-detected cases (age ≥12 weeks) in randomized clinical trials. OBJECTIVE To report the reported incidence of DDH in the English scientific literature and compare rates of late-detected cases in settings with different DDH screening strategies. DATA SOURCES PubMed, Scopus, and Web of Science databases were searched on November 25 and 27, 2021. No time filters were used in the search. STUDY SELECTION All observational studies reporting the incidence of early-detected or late-detected (age ≥12 weeks) DDH were included. Non-English reports were excluded if the abstract did not include enough information to be included for analysis. DATA EXTRACTION AND SYNTHESIS The number of newborns screened and the detection rates were extracted. Meta-analysis calculated the pooled incidence of DDH per 1000 newborns with 95% CIs using a random- or fixed-effects model. This study is reported according to the PRISMA and MOOSE guidelines. MAIN OUTCOMES AND MEASURES The main outcome measures were early detection, early treatment, late detection, and operative treatment incidences. RESULTS A total of 1899 studies were identified, 203 full texts were assessed, and 76 studies with 16 901 079 infants were included in final analyses. The early detection rate was 8.4 (95% CI, 4.8-14.8) infants with DDH per 1000 newborns with clinical screening, 4.4 (95% CI, 2.4-8.0) infants with DDH per 1000 newborns with selective ultrasonographic screening, and 23.0 (95% CI, 15.7-33.4) infants with DDH per 1000 newborns with universal ultrasonographic screening. Rates for nonoperative treatment were 5.5 (95% CI, 2.1-14) treatments per 1000 newborns with clinical screening, 3.1 (95% CI, 2.0-4.8) treatments per 1000 newborns with selective ultrasonographic screening, and 9.8 (95% CI, 6.7-14.4) treatments per 1000 newborns with universal ultrasonographic screening. The incidence of late-detected DDH was 0.5 (95% CI, 0.2-1.5) infants with DDH per 1000 newborns with clinical screening, 0.6 (95% CI, 0.3-1.3) infants with DDH per 1000 newborns with selective ultrasonographic screening, and 0.2 (95% CI, 0.0-0.8) infants with DDH per 1000 newborns with universal ultrasonographic screening. The corresponding incidences of operative treatment were 0.2 (95% CI, 0.0-0.9) operations per 1000 newborns with clinical screening, 0.5 (95% CI, 0.4-0.7) operations per 1000 newborns with selective ultrasonographic screening, and 0.4 (95% CI, 0.2-0.7) operations per 1000 newborns with universal ultrasonographic screening. CONCLUSIONS AND RELEVANCE This meta-analysis found that early detection rates and nonoperative treatments were higher with universal screening. The late detection and operative treatment rates with universal screening were similar to those among selectively and clinically screened newborns. Based on these results, universal screening may cause initial overtreatment without reducing the rates of late detection and operative treatment.

Abstract
ZusammenfassungDie Hüftdysplasie ist eine komplexe dreidimensionale Pathomorphologie des gesamten Hüftgelenks. Die mangelhafte Überdachung des Hüftkopfes führt zur Instabilität des Gelenks. Das schräg aufsteigende Dach ist Scherkräften ausgesetzt, die zu einer Überlastung der Erkerregion führen. Die Folge sind Schäden am chondrolabralen Komplex, welche die Ursache für auftretende Schmerzen sind und in weiterer Folge die Dysplasiearthrose induzieren. Die Inzidenz der Hüftdysplasie variiert nach geografischen Regionen und ethnischen Gruppen. Unterschiede in der Definition der Hüftdysplasie und ihrer Diagnose machen Literaturvergleiche schwierig. Die Biomechanik der dysplastischen Hüfte wird von der knöchernen Formgebung, aber auch von der Belastung und Muskelkräften beeinflusst. Die Behandlung sollte die Herstellung einer physiologischen Biomechanik zum Ziel haben, die in den meisten Fällen mehr eine Domäne der offenen Chirurgie als der Arthroskopie darstellt. Die Diagnosestellung der Hüftdysplasie ist herausfordernd. Eine genaue Anamnese, standardisierte klinische Tests und Röntgenaufnahmen, die durch den Chirurgen selbst beurteilt werden müssen, sind essenziell. Weiterführende Untersuchungen wie die Magnetresonanztomographie (MRT) sind für die Beurteilung von Knorpel- und Labrumschäden hilfreich.

Abstract
Objective: To describe and analyze the epidemiology and costs of surgical treatment of hip dysplasia in the Brazilian Public Health System. Methods: An ecological analytical study that evaluated a time series and the geographic distribution of surgical treatment of hip dysplasia in Brazil. Frequencies of cases, number of cases and associated factors were analyzed. Correlations, frequency maps and flow maps are presented and discussed. Results: During the study, 14,584 patients with dysplasia were admitted to hospitals according to Information Technology Department of the Public Health System. Patients underwent hospital treatment specific for dysplasia in 8,592 cases (at an average cost of R$ 2.225,50, total cost of R$ 19.124.086,25– updated values). In this group, mortality rate was 0.046% and mean hospitalization time was 4.41 days (standard deviation of 2,39 days). Age between 1 and 4 years (37.7%), female sex (64.5%) and white race (46%) were more frequent. Greater rates of specialists (R²=0.82; p<0.001), greater proportion of counties with high/very high human development index (R²=0.79; p<0.001), and higher per capita income (R²=0.68; p<0.001) correlated to greater rates of treatments undertaken per 1,000 live births (as per State of treatment). The factor most related to treatment rate per 1,000 live births (as per State of residence) was white race (R²=0.90; p<0.001). Southern states had higher treatment rates (as per State of residence, rate of 0.73/1,000), and Southeast states had greater absolute frequency of cases (46.7%) and greater flow of patients. Conclusion: The surgical treatment of hip dysplasia in Brazil occurs frequently, at relevant costs, and is distributed in a heterogenous and unequal fashion in the Public Health System. Southern states have a higher incidence of cases, and there is an association with racial and socioeconomic factors. There was no large variation in the incidence of cases over time.

Abstract
PURPOSE In India and other Global South countries, developmental dysplasia of the hip (DDH) is often diagnosed after walking age, leading to more invasive surgeries and long-term disability. DDH care pathways aim to enhance early detection and must be tailored to meet a country's needs and diverse practice settings. We describe a multi-phase methodology for context-specific DDH care pathway development, demonstrating its use in India. METHODS In Phase I, Orthopaedic surgeons, Pediatricians/Neonatologists, and Radiologists in India were surveyed regarding DDH screening. Seven relevant Indian organizations partnered together and assembled a multidisciplinary working group, which then met fortnightly to establish an evidence base and prepare for the subsequent consensus-building phase. During Phase II, panelists participated in a modified Delphi process to reach consensus on a list of DDH screening statements. Phase III applied the statements to develop the care pathway. RESULTS The Delphi process concluded after a preliminary survey and two Delphi rounds, reaching consensus on 47 statements, which were condensed into 35. The developed care pathway for India features periodic clinical hip examinations integrated with the country's immunization schedule and selective imaging screening, providing flexibility in the timing and modality of imaging. DISCUSSION/CONCLUSION In Global South countries, there is a need for DDH care pathways specific to local contexts. Successful care pathway development requires accounting for cultural differences in healthcare and strategies to facilitate engagement and to address country-specific barriers. This methodology was feasible in India and can be applied to other conditions and/or countries wishing to establish care pathways. LEVEL OF EVIDENCE Level III.

Abstract
Objectives
This study aims to evaluate the short-term results of infants who were radiologically diagnosed with developmental dysplasia of the hip (DDH), but in whom hip development was normal ultrasonographically. Patients and methods
Between January 2018 and September 2020, a total of 15 infants (2 males, 13 females; median age: 5 months; range, 4 to 6 months) who were diagnosed with DDH radiologically and treated were retrospectively analyzed. Hip ultrasonography was used for early diagnosis, treatment, and for follow-up in infants up to six months of age. While the ultrasonographic findings were normal, radiography was performed in infants between four to six months of age who were at risk for DDH. Results
Fifteen patients (22 hips) were diagnosed with DDH radiologically and treated. Radiologic dysplasia continued in seven hips of five patients during short-term follow-up. Conclusion
These results suggest that ultrasonographic hip maturation may not be consistent with normal hip development in infants, particularly in those who are at risk for DDH. In infants with DDH which is confirmed by radiography (less than 6 months of age), the diagnosis may be missed on ultrasonographic examination.

Abstract
AIMS The aim of this study was to assess screening costs in developmental dysplasia of the hip (DDH), to provide any clarity on the cost-effectiveness of various hip screening programmes internationally. METHODS A PROSPERO-registered systematic review was performed by examining cost analysis studies of various DDH screening programmes, including those based around clinical examination, selective ultrasound and universal ultrasound. Costs were analysed using narrative synthesis. RESULTS There were 14 studies included in this review. Two studies found that clinical hip screening is advantageous over no screening at all, both in terms of overall cost and favourable outcomes. When considering selective ultrasound imaging versus clinical screening, two studies found it to be more expensive, one found it cheaper and three studies calculated the overall programme costs to be similar. With universal ultrasound, four studies calculated this to be cheaper than clinical or selective ultrasound screening due to a reduced late detection and surgery rate. However, a comparable number of studies concluded that the increased financial costs of universal ultrasound were greater than the reduction in surgical costs. No studies included any long-term data. CONCLUSION There is a dearth of information on DDH screening costs, with significant heterogeneity amongst the existing literature. Future research should include the cost analysis of long-term complications of DDH, including the social and psychological impact of early onset arthritis, as well as gender specific ultrasound screening programmes.

Abstract
Background and purpose Total hip arthroplasty (THA) is a successful approach to treat unilateral symptomatic neglected hip dislocation (NHD). However, the extensive leg length discrepancy (LLD) can hereby only be partially corrected. In case of residual LLD of more than 2 cm, subsequent femoral lengthening can be considered. Patients/material/methods Retrospective analysis of clinical data and radiographs of five patients (age 38.1 (28–51) years) with unilateral NHD who underwent THA with (n = 3) or without (n = 2) subtrochanteric shortening osteotomy (SSO) and secondary intramedullary femoral lengthening through a retrograde magnetically-driven lengthening nail (follow-up 18.4 (15–27) months). Results LLD was 51.0 (45–60) mm before and 37.0 (30–45) mm after THA. Delayed bone union at one SSO site healed after revision with autologous bone grafting and plate fixation. Subsequent lengthening led to leg length equalisation in all patients. Complete consolidation was documented in all lengthened segments. Conclusion Staged reconstruction via THA and secondary femoral lengthening can successfully be used to reconstruct the hip joint and equalise LLD. The specific anatomical conditions have to be taken into consideration when planning treatment, and patients ought to be closely monitored.

Abstract
Developmental dysplasia of the hip comprises a broad spectrum of abnormalities in hip development, of variable severity. Besides physical examination, ultrasound is the preferred imaging modality for screening for developmental dysplasia of the hip in children aged younger than six months. The Graf method is the most widely used ultrasound technique for infant hips; a stepwise approach will be shown in this article. Furthermore, the process of dynamic ultrasound imaging will be explained as well as the use of transinguinal ultrasound in infants wearing a spica cast. There is no consensus on the best way to screen for developmental dysplasia of the hip, which is probably the reason why different screening programs exist throughout Europe, as will be discussed in this article. The use of universal versus selective ultrasound remains a controversy, as does the timing. Is it better to perform sonography in all newborn infants like in Germany and Austria? Or should we examine only the infants with clinical hip instability or risk factors (breech position, positive family history), like in the UK and the Netherlands? This article reviews the epidemiology, static and dynamic ultrasound techniques in screening for developmental dysplasia of the hip, and differences in screening programs throughout Europe. Set aside the uncertainties about whom and when to screen, it needs to be emphasized that ultrasound screening for developmental dysplasia of the hip is important, since the disease is initially occult and easier to treat when identified early. In this way, the radiologist can aid in preventing serious disability of the hip.

Abstract
Developmental dysplasia of the hip (DDH) is an important contributor to musculoskeletal morbidity, but effective strategies to screen for DDH remain controversial. The current utilization of hip ultrasound (US) screening for DDH in the United States is not defined. This study utilized Optum's de-identified Clinformatics® Data Mart, a large commercial and Medicare Advantage claims database. The frequency of DDH and hip US utilization was estimated using billing data on an average of 2.9 million relevant beneficiaries included annually from 2007 through 2017. A total of 6806 DDH cases were identified with an average annual prevalence of 1.7 per 1000 infants, which was stable during the study period. Girls were more likely to be screened and diagnosed with DDH, comprising 72% of DDH cases with an OR of 2.55 (95% CI 2.42-2.69), p < 0.001. Hip US screening was employed in 0.9% of the infant population on average but increased substantially from 2007 (0.4%) to 2017 (2.2%). Most common billing diagnoses included hip deformity (27.4%), breech delivery (20.4%), and physical exam abnormality (17.7%). The average imaging costs per patient for all screened children was $108.94. Insurance claims reflect the current American practice of selective hip US with relative adherence to American Academy of Pediatrics guidelines based on reported diagnoses. While hip US utilization increased during the study period, prevalence of DDH diagnoses did not increase. Our results suggest that expansion of hip US screening may not effectively increase DDH detection although further investigation is needed to ascertain optimal screening strategies to improve patient outcomes.

Abstract
BACKGROUND Developmental dysplasia of hip (DDH) is a common disorder of childhood and has a good prognosis when treated at an early age. In spite of being a significant concern, many children with DDH are not picked early and present late at walking age. In our country, it is presumed to be due to absence of a national policy for screening of DDH. Screening programmes including the combination of clinical and radiological methods in different ways have been suggested. However, the exact method of screening is controversial. PURPOSE To analyze effectiveness and cost-effectiveness of various screening methods for DDH. STUDY DESIGN Systematic review. METHODS This review was conducted in accordance with PRISMA guidelines. Medline database was explored for original case series and randomized clinical trials. Inclusion criteria were English language, screening for DDH in neonates, sample size more than 500, and studies with minimum duration of one year. RESULTS Thirty-four studies were selected to write the manuscript. This included 23 studies looking for effectiveness of a screening programme and 11 studies comparing various outcomes of different screening strategies. A trend favoring universal ultrasound screening was observed. CONCLUSION The literature supports universal ultrasound screening and has proved its cost-effectiveness. However, considering the logistic and financial challenges in our country, immediate implementation of universal ultrasound screening seems impractical. In the absence of any current guidelines for screening for DDH in India, we suggest professional organizations involved in the care of children and public health policy-makers to come together to develop national screening guidelines for DDH.

Abstract
OBJECTIVE To assess the effectiveness of early universal ultrasound (US) screening of developmental dysplasia of the hip (DDH). STUDY DESIGN A prospective study of universal hip screening of all mature neonates was conducted from 2012 to 2013, at the Department of Obstetrics and Gynaecology, University of Szeged; 1636 newborns (3272 hips) had clinical examinations and hip ultrasound by the Graf method within the1st 3 days of life. Prevalence of DDH, risk factors, sensitivity and specificity of clinical examinations were evaluated. RESULTS At the 1st US, 70 of the examined 3272 hips (2.14%) were found to be positive. According to Graf categories, the following distribution was observed: type II C, 21 hips (30.0%); D, 24 hips (34.28%); III, 24 hips (34.28%); IV, 1 hip (1.44%). Regarding the risk factors, female gender, breech presentation and positive family history proved to be significant. Interestingly, 28 (50.90%) of the 55 newborns with DDH had neither positive physical signs nor any risk factors, except being female. The physical examination was calculated for sensitivity (20.0%) and specificity (98.34%). CONCLUSIONS In our 1-year period study, 50.9% of the newborns with DDH had neither any positive physical signs nor any risk factors, except being a female. In contrast, early universal US screening of the hip facilitated to diagnose all cases with hip dysplasia. Hip sonography is an effective mode of prevention in orthopaedics, however further studies are needed to compare the rates of operative procedures in selective versus universal screening models.

Abstract
PURPOSE Late-diagnosed dislocated hips underwent open reduction, Dega osteotomy, and proximal femoral osteotomy between 1968 and 1988. The objectives of this study are to assess the survival of hips into adulthood, clinical and radiological outcome, patients' life perspectives and the risk factors of failure. METHODS An assessment of 67 hips treated when younger than five years (<age 5yr. group) and 71 hips in the group aged older than five years (+age 5yr.) was performed. All cases were evaluated clinically and radiographically, and survival was assessed, considering hip replacement as endpoints for failure (abbreviation HR+ refers to hips that underwent hip replacement surgery; HR- refers to hips that have not been replaced at the follow-up). The fertility rate and the social security disability benefits (SSDB) recipiency percentage were calculated. RESULTS The 40-year survival rates were 73% (95% confidence (CI) 71% to 76%) in the <age 5yr. group, 54% (95% CI 51% to 57%) in the +age 5yr. group, 70% (95% CI 67% to 73%) in one-sided dislocations and 57% (95% CI 54% to 60%) in bilateral dislocations. At follow-up, the median Harris hip and Western Ontario and McMaster Universities Osteoarthritis scores were 90.0 and 13.0 (<age 5yr. group, HR-), 74.0 and 28.0 (+age 5yr. group, HR-), 90.0 and 16.0 (<age 5yr. group, HR+) and 84.5 and 11.5 (+age 5yr. group, HR+), respectively. The operation normalized the radiological parameters. The correlation between the grade of femoral head avascular necrosis (AVN) at a median 2.6 years after the operation and the grade of osteoarthritis at follow-up was 0.38 (p < 0.001). The fertility rate was 1.54. In total, 16.0% (aged under five years) and 38.5% (aged over five years) of patients were receiving SSDB (p = 0.003). CONCLUSION Early failure risk factors are older age at the surgical procedure, high AVN grade and bilateral hip involvement. Still, the results facilitate hip reposition whenever technically manageable, even in teenagers. LEVEL OF EVIDENCE III.

Abstract
Hip flexion and abduction is fundamental for developmental dysplasia of the hip (DDH) treatment. At present, double diaper treatment has been inappropriately adopted when DDH is suspected. The aim of this study was to verify whether double diapers influence a newborn’s hip position. Here, we studied 50 children (23 female; 27 male; average age 62.33 ± 20.50 days; average birth weight 3230 ± 447 g) with type I hips according to Graf. At the same time of the ultrasound (US) examination, the following hip positions were measured using a manual protractor: (1) spontaneous position, supine on the outpatient bed without a diaper; (2) spontaneous position, with a double diaper; and (3) squatting position on the caretakers’ side. Statistical analysis was performed with a t-test to compare between (1) the spontaneous position without a diaper and with double diapers; (2) the spontaneous position with double diapers as well as the squatting position on the caretakers’ side with a diaper. The comparison between the hip position without diaper and with double diapers was statistically not significant for all measurements, i.e., right hip flexion (p < 0.33), left hip flexion (p < 0.34), and right and left hip abduction (p < 0.87). The comparison between the hip position with double diapers and on the caretakers’ side was statistically significant for all measurements, i.e., right hip flexion (p < 0.001), left hip flexion (p < 0.001) and right and left hip abduction (p < 0.001). We found that the use of double diapers did not affect hip position, while the position formed on the caretaker’s side shows favorable influence.

Abstract
OBJECTIVE We evaluated the effect of early universal ultrasound (US) screening program for developmental dysplasia of the hip (DDH). METHODS A total of 21,676 newborns between 2006 and 2015 were included in the study. All hips were examined by US within the first week of life. The incidence of sonographic hip-types according to the Graf method was analyzed, and then followed prospectively. Risk factors for DDH and treatment measures were also recorded, together with the number of first surgical procedures before the age of three years. RESULTS Overall, 92.5% of hips were mature (Graf types Ia, Ib) at first examination, 7.2% were mature (Graf type IIa) and 0.3% were pathological (Graf types IIc to IV). A total of 146 pathological hips were detected in 118 of newborns (0.6%). Only 0.26% of screened population was treated with an orthosis. The rate of first surgical procedures and the rate of late detected DDH were 0.23 and 0.09 per 1000 live births, respectively. Regarding risk factors, positive family history, female gender, breech presentation, and high birth weight were significantly more common in newborns with pathological hips. CONCLUSION Early neonatal universal US screening using Graf method is recommended to timely detect DDH and to provide the optimal conservative approach of management. It seems to be effective in reducing the overall treatment rate, together with the rate of surgical procedures and late detected cases.

Abstract
AIM Australia utilises a selective ultrasound screening programme. The rate of late diagnosis of developmental dysplasia of the hip (DDH) in Australia is increasing. The aim of this study is to quantify the treatment required and compare the 5-year radiological outcomes between early and late diagnosis in children with DDH with frank dislocation. METHODS We performed a case-matched control study of children with frank DDH dislocations from 2000 to 2010 comparing three groups: children with an early diagnosis successfully treated in a Pavlik harness (SP), children with an early diagnosis who failed Pavlik harness treatment (FP) and children with a late diagnosis (LD). Minimum follow-up was 4 years. RESULTS A total of 115 hips were included. Patients in the LD group required significantly more open reductions (P < 0.001), acetabular osteotomies (P < 0.001) and femoral osteotomies (P < 0.001). LD was also associated with significantly higher rates of growth disturbance at 46.3%, compared to 20.6% in the FP group and 5% in the SP group (P < 0.001). Overall, there were excellent radiological outcomes in 58.5% of the LD group compared to 79.4% in the FP group and 100% in the SP group. CONCLUSION In Australia, high rates of LD in DDH persist in the context of selective ultrasound screening. While good radiological outcomes are achievable, a significantly greater level of surgical intervention is required and this is associated with significantly higher rates of growth disturbance. Optimisation of screening in Australia is vital.

PARTICIPANTS Of 126 children with hip dislocation diagnosed later than 14 days age in the 2000-2009 birth cohort, 101 had complete data and were included in the study. INTERVENTIONS The entire birth cohort was subject to clinical screening for hip instability at 6-8 weeks, 6 months and 10-12 months age. Children diagnosed through this screening were compared with children presenting due to symptoms, which was used as a surrogate variable representing a situation without secondary screening. MAIN OUTCOME MEASURES Age at diagnosis and disease severity of late presenting hip dislocations. RESULTS Children diagnosed through secondary screening were 11 months younger (median: 47 weeks) compared with those presenting with symptoms (p<0.001). Children diagnosed through secondary screening had 11% risk of having a high (severe) dislocation, compared with 38% for those diagnosed due to symptoms; absolute risk reduction 27% (95% CI: 9.7% to 45%), relative risk 0.28 (95% CI: 0.11 to 0.70). Children presenting due to symptoms had OR 5.1 (95% CI: 1.7 to 15) of having a high dislocation, and OR 11 (95% CI: 4.1 to 31) of presenting at age 1 year or older, compared with the secondary screening group. The secondary screening was able to identify half of the children (55%, 95% CI: 45% to 66%) not diagnosed through primary screening. CONCLUSIONS Secondary screening at child healthcare centres may have substantially lowered the age at diagnosis in half of all children with late presenting hip dislocation not diagnosed through primary screening, with the risk of having a high dislocation decreased almost to one-quarter in such cases.

Abstract
BACKGROUND The aim of this study was to assess the accuracy of clinical screening examination in newborns with dislocated hips compared with ultrasound scan (USS). METHODS Newborns, up to 3 months of age, with confirmed hip dislocations on USS were prospectively enrolled in a multinational observational study. Data from 2010 to 2016 were reviewed to determine pretreatment clinical examination findings of the treating orthopaedic surgeon as well as baseline ultrasound indices of developmental dysplasia of the hip (DDH). All infants had been referred to specialist centres with expertise in DDH, due to abnormal birth examination or risk factor. RESULTS The median age of the study population was 2.3 weeks and 84% of patients were female. Of the total 515 USS-confirmed dislocated hips included in the study, 71 (13.8%) were incorrectly felt to be reduced on clinical examination by the treating orthopaedist (P<0.001). Full hip abduction was documented in 106 hips. Of the hips correctly identified as dislocated, 322 hips were further analyzed based on clinical reducibility. Thirty-three of 322 (10.2%) were incorrectly thought to be reducible when in fact they were irreducible or vice versa. CONCLUSIONS Expert examiners missed a significant number of frankly dislocated hips on clinical examination and their ability to classify hips based on clinical reducibility was only moderately accurate. This study provides evidence that, even in experienced hands, physical examination findings in DDH are often too subtle to elicit clinically in the first few months of life. This may explain the persistent and measurable rate of late presenting dislocations in countries with screening programmes reliant on clinical examination. LEVEL OF EVIDENCE Level 1-testing of previously developed diagnostic criteria in series of consecutive patients (with universally applied reference "gold" standard).

Abstract
BACKGROUND We evaluated screening, referral and treatment practices for developmental dysplasia of the hip (DDH) in India by surveying Orthopaedic surgeons who treat patients with DDH. The survey assessed the timing of DDH presentation, resource availability, and current state of screening and diagnosis, which would help in the development of a DDH care pathway for India. METHODS An online survey was distributed to Orthopaedic surgeons practicing in India via email and administered onsite to those attending the annual conference of the Pediatric Orthopaedic Society of India in 2019. RESULTS 173 completed surveys were received from surgeons practicing in a predominantly urban setting. 68.8% of respondents had performed initial evaluations on children with DDH aged over 1 year in the past 12 months, and 49.1% had assessed children with DDH aged > 2 years on initial presentation. There was no consistent use of established guidelines, with only 30% of respondents stating that a care pathway was in place at their institution. However, 91.9% would support the implementation of a care pathway developed in India, to decrease the incidence of delayed diagnosis and facilitate earlier intervention. 85% of respondents had ready access to ultrasound scans and 95.4% had access to X-rays. CONCLUSIONS In India, there is still a large number of late-presenting cases of DDH, which could be improved with effective screening. The development of a care pathway for DDH in India is well-supported by Orthopaedic surgeons and may help decrease the incidence of late presenting cases; potentially improving outcomes, decreasing morbidity, and upskilling local practitioners.

Abstract
PURPOSE Mongolia is the first Asian country to launch universal ultrasound screening for newborns with developmental dysplasia of the hip (DDH). The aims of this study were to determine the coverage and treatment rate of this programme. METHODS Data from birth statistics and ultrasound hip screening from 29 hospitals were retrospectively reviewed (2010 to 2016, pre-nationwide phase; and 2017 to 2019, nationwide programme). DDH was diagnosed using the Graf-technique and treated according to 'ABCD', a modified Graf classification (Group A: Graf Type 1, mature; B: 2a, physiologically immature; C: 2c to 3, early DDH; D: 4, dislocated). Group B children were followed with monthly ultrasound. Group C and D children were treated with a flexion and abduction orthosis (Tübingen). Screeners used a web-based platform to upload images for quality surveillance. RESULTS Between 2017 and 2019, 230 079 live births were registered and 176 388 newborns screened. The nationwide screening coverage rate in newborns increased from 73.6% in 2017 to 82.1% in 2019. Group A (148 510 children, 84.2%) was discharged, while Group B (25 820, 14.6%) was followed. Among children in Group B, 284 cases worsened to Group C and were, therefore, treated with a Tübingen orthosis. The remaining 2058 (1.2%) of newborns with DDH were treated with a Tübingen orthosis, including 1999 newborns in Group C and 59 in Group D. Since 2017, a total of 142 860 (81.0%) hip sonograms were uploaded to the platform. CONCLUSION A simplified diagnostic and therapeutic framework for ultrasound DDH screening for newborns was successfully deployed in Mongolia, a developing country, providing high surveillance coverage and appropriate treatment.Level of evidence: IV.

Abstract
The purpose of this study is to state the reliability of neonatal hip ultrasound interpretation, defining the intra and interoperator variability in the evaluation of the scans. We considered a sample of 2071 scans (coming from 798 patients who attended the screening programme for hip dysplasia), which were interpreted by the operator who obtained and read the images at the screening time and then by a different operator who saw the images for the first time. Both the intra and interoperator variability of α and β angles' values resulted statistically not significative (intraclass correlation coefficient > 0.8) and determining a class shift (according to the Graf's classification) in a nonstatistically significative number of cases (agreement percentage >91% and Cohen's κ >0.8). Hip sonography can reliably detect hip dysplasia and the intra and interoperator variability in the interpretation of the exam is NS when the examination is correctly executed.

Abstract
The aim of this study was to determine the relationship of tangent to the lateral roof angle (TLRA), Graf's alpha angle and percentage femoral head cover (PHC) and to observed stability, and to establish intraobserver and interobserver errors for measurement of alpha angle and TLRA. In total, 2235 babies referred to the hip review clinic over a period of 8 years. Intraobserver and interobserver errors were calculated from readings of 383 hip images by an experienced paediatric radiologist and a trainee. Taking TLRA <70° as abnormal resulted in sensitivity for unstable right hips of 88% compared with 77% for alpha angle <60° (P = 0.002) and 81% for PHC <60% (P = 0.028) and specificity of TLRA 89%, alpha angle 90% (P = 0.07) and PHC 83% (P < 0.001). Corresponding figures for left hips are sensitivity of TLRA 99%, alpha angle 91% (P < 0.001) and PHC 96% (P = 0.013), and specificity TLRA 86%, alpha angle 83% (P = 0.001) and PHC 67% (P < 0.001). Mean intraobserver errors for alpha angle were 1.85° and 1.81° for consultant and trainee compared to 2.54 and 2.55 for TLRA. Mean interobserver errors were 2.22 for alpha angle and 3.42 for TLRA. TLRA, a new parameter, correlated better with observed stability with significant improvement in sensitivity in both hips and specificity in left hips compared with Graf's alpha angle, and significantly improved sensitivity and specificity in both hips compared with percentage femoral head cover.

Abstract
AIMS 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. METHODS 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. RESULTS Evidence-based changes were made to the Northern Ireland screening programme, including an increase in ultrasound scanning capacity and expansion of nurse-led screening clinics. The number of infant hip ultrasound scans increased from 4,788 in 2011, to approximately 7,000 in 2013 and subsequent years. The number of hip radiographs on infants of less than one year of age fell from 7,381 to 2,208 per year. There was a modest increase in the treatment rate from 10.9 to 14.3 per 1,000 live births but there was a significant reduction in the number of closed hip reductions. The incidence of infants diagnosed with DDH after one year of age was 0.30 per 1,000 live births over the entire period. CONCLUSION Improving compliance with the regional infant hip screening protocols led to reduction in operative procedures and reduced the number of pelvic radiographs of infants. We conclude that performance monitoring of screening programmes for DDH is essential to provide a quality service. Cite this article: Bone Joint J 2020;102-B(4):495-500.

Abstract
BACKGROUND Atraumatic hip pain in children is one of the most common symptoms with which pediatricians, orthopedists, and general practitioners are confronted, with an incidence of 148 cases per 100 000 persons per year. METHODS This article is based on publications up to April 2019 that were retrieved by a selective search in the PubMed data- base, including case reports and reviews. RESULTS Infants with fever often have purulent coxitis, which can be diagnosed by blood tests and ultrasonography. Toddlers and older children may suffer from painful restriction of motion of the hip joint, associated with limping (antalgic gait) or even the in- ability to walk. The main elements of the differential diagnosis in children aged 2-10 are coxitis fugax and idiopathic necrosis of the femoral head (Perthes disease). In children aged 10 and up, and in adolescents, slipped capital femoral epiphysis (SCFE) is typical. Bone tumors and rheumatic diseases must always be considered as well. The initial diagnostic steps on presentation of a child with restricted hip movement should be plain x-rays and joint ultrasonography for the detection of an effusion. Suspicion of a tumor is the main indication for tomographic imaging (computed tomography or magnetic resonance imaging). CONCLUSION The underlying cause of hip pain in children should be diagnosed early to avoid adverse sequelae.

Abstract
IMPORTANCE Developmental dysplasia of the hip, including late-diagnosed hip dislocation, is the leading cause of hip arthroplasties in young adults. Early treatment is essential for a good prognosis. Before the institution of a national screening program, a minimum of 0.9 per 1000 Swedish children were affected. OBJECTIVES To evaluate the incidence of late-diagnosed hip dislocation among children who undergo clinical screening as neonates and to study antenatal and perinatal risk factors for late-diagnosed hip dislocation. DESIGN, SETTING, AND PARTICIPANTS This nested case-control study included children born in Sweden from January 1, 2000, through December 31, 2009. All maternity wards, maternal health units, and orthopedic departments in Sweden participated. Children with a late-diagnosed hip dislocation were matched by sex and birth year to randomly selected controls in a 1:10 ratio. Potential risk factors in pregnant women and newborns were recorded, and cases of hip dislocation were registered. Observation time ranged from 8 to 18 years, with the last data analysis in January 2019. EXPOSURES Clinical hip examinations neonatally and at 6 to 8 weeks, 6 months, and 10 to 12 months. MAIN OUTCOMES AND MEASURES Hip dislocation diagnosed more than 14 days after birth, age at diagnosis, and severity of dislocation. RESULTS Among 1 013 589 live births (521 728 [51.5%] boys), 126 children (0.12 [95% CI, 0.10-0.15] per 1000 live births) had a late-diagnosed hip dislocation at a median age of 31.4 weeks (interquartile range, 16.1-67.1 weeks; 95% CI, 27.4-44.1 weeks). The incidence of late-diagnosed hip dislocation was 9 times higher among girls (113 of 491 861; 0.23 [95% CI, 0.19-0.28] per 1000 live births) than among boys (13 of 521 728; 0.02 [95% CI, 0.01-0.04] per 1000 live births). Twenty-one children (0.02 per 1000 live births) had high (severe) dislocations. Breech delivery (adjusted odds ratio, 3.07; 95% CI, 1.34-7.02), short body length at birth (adjusted odds ratio, 0.86; 95% CI, 0.76-0.98, per additional 1 cm), and being large for gestational age (adjusted odds ratio, 3.59; 95% CI, 1.30-9.95) were independent risk factors. Maternal smoking at the first visit to the maternal health care center was less common among children with hip dislocation (adjusted odds ratio, 0.16; 95% CI, 0.04-0.70). CONCLUSIONS AND RELEVANCE Compared with historical data, the incidence of late-diagnosed hip dislocation in Swedish-born children appears to have decreased substantially since the screening program was initiated, as have the age at detection and disease severity. Similar screening programs should also be possible to institute in upper-middle- and lower-middle-income countries.

Abstract
BACKGROUND Congenital hip dislocation (luxation) has an incidence of 0.4 - 0.7% and is regarded as a prearthrotic deformity. Thus, if not being diagnosed and treated at a very early age, extensive surgical measures are inevitable in childhood and early adulthood. METHODS In the time between 01/2013 and 02/2019 we performed 28 600 hips sonographies in babies as part of general screening measures at U2 or U3. There were 71 instable, dysplastic or dislocated hips diagnosed that were treated by arthrographic, closed reduction. After a hip spica cast was applied, reposition was controlled by MRI, estimating the acetabular head index (ACI), the head coverage index (HCI) as well as the femoral head's sphericity or by sonography using the Graf method. RESULTS Overall success rate was 91.6% for primary closed reduction. Patients with primarily irreducible hips were significantly older (p < 0.003) than patients with primarily successful reducible hips. Congenital dislocated hips had significantly higher ACIs (p < 0.001) and HCIs (p = 0.03) as well as significantly less well rounded femoral heads (sphericity; p < 0.001) compared to stable hips. CONCLUSION Early diagnosis and treatment of congenital dislocated hips by closed reduction is essential for a sufficient and regular maturation of the hips without further surgical interventions.

Abstract
BACKGROUND Developmental dysplasia of the hip (DDH) is a preventable and treatable disorder in children. Hip ultrasound is recommended for early detection of affected hips. The timing of the initial hip ultrasound and the frequency of subsequent ultrasounds are controversial topics when considering costs and efficiency. METHODS Registry data from the Taiwanese Screening and Audit System for Developmental Dysplasia of the Hip were obtained for biometry of hip ultrasounds using the Graf classification and relevant demographic data from 2016. Initial screening results and final case management outcomes were compared to determine screening accuracy and the number of visits needed to determine final outcomes. RESULTS In total, we screened 1683 newborns in 2016. Of the initial cases screened within 28 days (n = 1168), 86.6% were negative, 10.1% positive, and 3.3% intermediate, while of the cases screened after 28 days (n = 515), 97.3% were negative, 0.8% positive, and 1.9% intermediate. Screening of the newborns' final hip outcomes revealed that 1641 (97.6%) were negative, treatment was administered in 8 cases (0.4%), and 34 (2.0%) cases were lost to follow-up. When comparing screening times, screening after 28 days improved specificity (89%-97%), and later screenings were associated with fewer visits needed to confirm hip outcomes (aOR = 0.19, CI95% = 0.10-0.38, p < 0.001) and improved accuracy (aOR = 13.84, CI95% = 4.23-45.26, p < 0.001). CONCLUSION This study provides evidence of the benefits of screening for DDH after 28 days, namely: reduced false positives, improved screening accuracy, and a reduced requirement for follow-up visits. Delaying screening can also potentially reduce unnecessary parental anxiety, eliminate unnecessary healthcare burdens, and reduce costs. We recommend performing hip ultrasound screening for newborns after 28 days.

Abstract
INTRODUCTION Developmental dysplasia of the hip (DDH) is still a common and important disorder of childhood, with a prevalence of 0.1 to 2/1000 children. Using ultrasonography (US) in screening of DDH reduces the rates of open reductions and complications. In the current study, we aim to detect the optimal time for US examination for detecting DDH to prevent unnecessary repeating US examinations and treatments. METHODS Children referred to US examination for a healthy child screening program, according to the health policy of our country, are included in the current prospective study. Both hips of each child were sonographically examined by the same radiologist using Graf's method at 4th, 8th, 12th weeks of life. RESULTS A total of 2020 hips of 1010 children were examined. Fourth-week US results can predict 12th-week results (right hip: sensitivity 100%, specificity 75.7%; left hip: sensitivity 100%, specificity 78.3%). Eighth-week US results can predict 12th-week results (right hip: sensitivity 100%, specificity 87.5%; left hip: sensitivity 100%, specificity 83.9%). In predicting 12th-week US results, 8th-week results are found to be more successful than 4th-week results. CONCLUSIONS Late diagnosis of DDH might cause serious public health problems. On the other hand, early US examinations can result in false-positive diagnosis. Unfortunately, there is still confusion about the optimal time for DDH screening with US, especially among radiologists who are not specialized in DDH sonography. A US scan performed at eighth week of life can predict any pathology presence safely and correctly.

Abstract
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. PATIENTS AND METHODS 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. RESULTS The incidence of late-diagnosed DDH was 1.28 per 1000 live births. Within the study population, 754 children were identified with a diagnosis of DDH after one-year of age. Of all late diagnoses, 536 (71.1%) were detected between one to two years of age. There were 608 female patients (80.6%) and 146 male patients (19.4%), giving a female-to-male ratio of 4.2:1. Distribution was evenly spread throughout England. CONCLUSION The incidence of late-diagnosed DDH has not been reduced from that reported 35 years ago, prior to the introduction of the national selective screening programme for DDH.
