[PMID: 38355007 DOI: 10.1016/j.otsr.2024.103836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 01/30/2024] [Accepted: 02/07/2024] [Indexed: 02/16/2024]
Abstract
INTRODUCTION Developmental dysplasia of the hip (DDH) is a prevalent condition in children. Currently, the exact etiology of DDH remains uncertain. The objective of this study was to conduct a meta-analysis to investigate the risk factors associated with DDH in infants. The findings would provide a theoretical foundation for targeted early screening and diagnosis. HYPOTHESIS Several indicators, such as gender, intrauterine position, family history of DDH, gestational age, delivery mode, amniotic fluid levels, swaddling, parity, fetus number, combined musculoskeletal deformities, birth weight, and physical examination results, may serve as risk factors for DDH. MATERIALS AND METHODS Cohort studies investigating the risk factors of DDH in infants through logistic regression analysis were searched in the Wanfang, VIP citation, China National Knowledge Infrastructure (CNKI), China Biology Medicine disc, Excerpta Medica Database (Embase), PubMed, and Cochrane Library databases up to May 2023. After extracting the data from eligible literature and assessing them using the Newcastle-Ottawa Scale (NOS), articles were selected based on pre-established inclusion and exclusion criteria. RESULTS A total of eleven literature reports covering 979,757 infants were included in this meta-analysis. The publication bias did not significantly influence the results. The incidence rate of DDH was 47.99‰ among infants with risk factors compared to 3.21‰ in the general population. Risk factors for DDH included being female (OR=6.97, 95% CI: 5.18-9.39, p<0.001), breech delivery (OR=4.14, 95% CI: 3.09-5.54, p<0.001), positive family history (OR=4.07, 95% CI: 2.20-7.52, p<0.001), cesarean section (OR=1.11, 95% CI: 1.01-1.21, p=0.032), oligohydramnios (OR=3.93, 95% CI: 1.29-12.01, p=0.016), swaddling (OR=6.74, 95% CI: 1.25-36.31, p=0.026), firstborn status (OR=1.84, 95% CI: 1.49-2.53, p<0.001), combined musculoskeletal malformations (OR=2.27, 95% CI: 1.58-3.27, p<0.001), and physical signs of DDH (OR=8.71, 95% CI: 2.44-31.07, p=0.001). Premature delivery (OR=0.91, 95% CI: 0.88-0.95, p<0.001) was a protective factor for DDH. The relationship between multiple pregnancies (OR=0.58, 95% CI: 0.33-1.02, p=0.060) and low birth weight (OR=0.62, 95% CI: 0.14-2.76, p=0.529) in relation to DDH remained uncertain. DISCUSSION This meta-analysis shows that female, breech delivery, positive family history, cesarean section, firstborn status, oligohydramnios, swaddling and combined musculoskeletal malformations are associated with DDH. Premature delivery appeared to be a protective factor against DDH. Nevertheless, the other factors need more research to reach more conclusive results. LEVEL OF EVIDENCE III; meta-analysis.

Abstract
Human and veterinary medicine have historically presented many medical areas of potential synergy and convergence. Mechanical osteoarthritis (MOA) is characterized by a gradual complex imbalance between cartilage production, loss, and derangement. Any joint instability that results in an abnormal overload of the joint surface can trigger MOA. As MOA has a prevailing mechanical aetiology, treatment effectiveness can only be accomplished if altered joint mechanics and mechanosensitive pathways are normalized and restored. Otherwise, the inflammatory cascade of osteoarthritis will be initiated, and the changes may become irreversible. The management of the disease using non-steroidal anti-inflammatory drugs, analgesics, physical therapy, diet changes, or nutraceuticals is conservative and less effective. MOA is a determinant factor for the development of hip dysplasia in both humans and dogs. Hip dysplasia is a hereditary disease with a high incidence and, therefore, of great clinical importance due to the associated discomfort and significant functional limitations. Furthermore, on account of analogous human and canine hip dysplasia disease and under the One Medicine concept, unifying veterinary and human research could improve the well-being and health of both species, increasing the acknowledgement of shared diseases. Great success has been accomplished in humans regarding preventive conservative management of hip dysplasia and following One Medicine concept, similar measures would benefit dogs. Moreover, animal models have long been used to better understand the different diseases' mechanisms. Current research in animal models was addressed and the role of rabbit models in pathophysiologic studies and of the dog as a spontaneous animal model were highlighted, denoting the inexistence of rabbit functional models to investigate therapeutic approaches in hip MOA.

Establishment of an ultrasound-guided protocol for the assessment of hip joint osteoarthritis in rabbits-A sonoanatomic study. PLoS One 2023; 18:e0291177.

Abstract
Ultrasound (US) has emerged as one of the most applied imaging tools to diagnose musculoskeletal disorders and assist in guided intra-articular administrations. Nevertheless, in evaluating the rabbit hip joint, there is a need for an ultrasonographic approach. Therefore, this study aimed to describe the hip sonoanatomy, develop and validate a US-guided protocol to assess the hip joint in rabbits and apply this protocol in vivo. This study was carried out in three phases, phase I: a pilot cadaveric study, to assess the applicability of different US approaches in the hip of rabbits and, consequently, develop a detailed US-guided protocol (2 rabbit cadavers, n = 4 hips); phase II: validation of the established US-guided protocol through a numerical scoring system in healthy joints (11 rabbit cadavers, n = 22 hips), and, lastly, phase III: application of the US-guided protocol in vivo in osteoarthritic joints (5 rabbits, n = 5 hips). A total of six planes were validated, two in the ventral approach and four in the dorsal approach. The ventral transverse plane was deemed more informative regarding the hip joint sonoanatomy, enabling the identification of a greater number of structures when compared to the other planes. Nevertheless, this study suggested that the isolated application of a plane was deemed insufficient for a complete and detailed evaluation of the hip joint anatomy, rendering it necessary to employ other planes complementarily. Furthermore, the established US-guided protocol allowed a definitive diagnosis of OA, and osteophytes and capsular hypertrophy were among the defects most frequently detected. This novel study provided US anatomical landmarks for forthcoming therapeutic research and monitoring of OA development, granting the accurate identification of osseous and cartilaginous defects.

Abstract
OBJECTIVES This study investigated the progression of pubofemoral distance (PFD) with age and assessed the correlation between PFD and late acetabular index (AI) measurements. METHODS This prospective observational study was conducted between January 2017 and December 2021. We enrolled 223 newborns who underwent the first, second, and third hip ultrasounds, and pelvis radiograph at a mean age of 18.6 days, 3.1 months, 5.2 months, and 6.8 months, respectively. The difference between PFD measured at serial ultrasounds and the correlation with AI were analyzed. RESULTS The PFD increased significantly (p < 0.001) at serial measurements. The mean PFD at the first, second, and third ultrasounds were 3.3 (2.0-5.7), 4.3 (2.9-7.2), and 5.1 (3.3-8.0) mm, respectively. The PFD at three ultrasounds were all significantly (p < 0.001) and positively correlated with AI, with the Pearson correlation coefficients being 0.658, 0.696, and 0.753 for the first, second, and third ultrasounds, respectively. Using AI as reference, the diagnostic ability of PFD was calculated by the areas under the receiver operating characteristic curve, which was 0.845, 0.902, and 0.938 for the first, second, and third PFD, respectively. For the first, second, and third ultrasounds, PFD cutoff values of ≥ 3.9, ≥ 5.0, and ≥ 5.7 mm, respectively, yielded the greatest sensitivity and specificity in predicting late abnormal AI. CONCLUSION The PFD naturally progresses with age and is positively correlated with AI. The PFD has potential for predicting residual dysplasia. However, the cutoff for abnormal PFD values may require adjustment according to the patient's age. KEY POINTS • The pubofemoral distance measured in hip ultrasonography naturally increases as the infant's hips mature. • The early pubofemoral distance demonstrates a positive correlation with late acetabular index measurements. • The pubofemoral distance may help physicians predict abnormal acetabular index. However, the cutoff for abnormal pubofemoral distance values may require adjustment according to patient's age.

Abstract
Developmental dysplasia of the hip (DDH), if uncorrected, can result in several chronic abnormalities, including chronic hip pain, degenerative arthritis, and gait abnormalities. The outcome of DDH generally depends on the age of presentation; a worse prognosis is linked to a higher age of presentation. Although treatment continues to be a challenge, recent advancements in the field have improved our understanding of the disease, which has resulted in advancements in DDH surveillance during infancy and the reduction of complications with early intervention. The databases used for this overview include Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Library, MEDLINE, and EMBASE. These databases were used to search for ongoing trials related to the management and diagnosis of DDH.

Abstract
Background Developmental dysplasia of the hip (DDH) is one of the most common hip pathologies in pediatric age group and late diagnosis remains a major concern in Saudi Arabia. Objective The aim of this study is to examine the ability of Saudi Arabian pediatricians and family physicians to conduct clinical screening for (DDH) by estimating their clinical knowledge and skills and analyzing the gaps therein to determine whether there is potential to launch a national screening protocol for DDH in Saudi Arabia. Methods This is a multicenter cross-sectional study from three major regions in Saudi Arabia (Central, Eastern and Western provinces). The assessed aspects are risk factors, age of screening, incidence in Saudi Arabia, physical signs and diagnostic markers, and treatment, along with their 'clinical knowledge and skills' score. Results Half of the participants were pediatricians, while the rest were family physicians. More than a third of the participants were considered to have adequate knowledge, ie, above the mean score. Dimensions with the most significant knowledge gaps included the incidence of DDH in Saudi Arabia, adverse effects of swaddling, and the management of a high-risk infants presenting with a negative physical examination. Additionally, there were relatively low rates of awareness regarding positive risk factors as well as a generally poor ability to identify physical signs. Clinical knowledge and skill levels were significantly lower among family physicians. Conclusion Pediatricians and family physicians in Saudi Arabia still need further training to improve their clinical skills for DDH screening. The proper administration of training programs could eventually enable the gradual implementation of a national systematic screening program.

Abstract
Developmental dysplasia of hip seriously affects the health of children, and pelvic osteotomy is an important part of surgical treatment. Improving the shape of the acetabulum, preventing or delaying the progression of osteoarthritis is the ultimate goal of pelvic osteotomies. Re-directional osteotomies, reshaping osteotomies and salvage osteotomies are the three most common types of pelvic osteotomy. The influence of different pelvic osteotomy on acetabular morphology is different, and the acetabular morphology after osteotomy is closely related to the prognosis of the patients. But there lacks comparison of acetabular morphology between different pelvic osteotomies, on the basis of retrospective analysis and measurable imaging indicators, this study predicted the acetabular shape after developmental dysplasia of the hip pelvic osteotomy in order to help clinicians make reasonable and correct decisions and improve the planning and performance of pelvic osteotomy.

Abstract
Congenital Hip Dysplasia (CHD) is characterized by a hip joint dislocation between the femoral head and the acetabulum, with a multifactorial etiology. This disorder can be an isolated condition or the manifestation of a syndromic condition, and it has been estimated with higher rates than registered, with a predominance in female sex and left side; risk factors are now defined. In Italy, the incidence rate is 3-4%, with significant regional differences: higher in Lombardy and lower in Sicily. Because clinical examination alone is insufficient to diagnose CHD, it is supplemented with ultrasonography and X-ray if necessary. Surveillance, static or dynamic splints, or osteotomies are the only treatment options. The goal of this study was to evaluate our experience in terms of management and conservative treatment of all newborns from January 2018 to May 2022: female sex and left hip were major involved, risk factors were not significant in our case, but results from early diagnosis and treatments, in terms of better outcome, were interesting. After a strict 6-month follow-up period, 89.13% of the patients were classified as grade Ia or Ib according to the Graf classification system. Finally, we emphasize the importance of early universal screening and subsequent diagnosis to allow for early treatment of the disorder, at an age when conservative treatments can yield good results.

Abstract
Developmental hip dysplasia (DDH) is a paediatric condition in which the 'ball and socket' hip joint fails to form properly during infancy. The increased mechanical stress on the hip joint from DDH can contribute to the development of osteoarthritis during adulthood. Therefore, careful physical examination and imaging of all infants to diagnose DDH is critical to provide the best possible functional outcome. Ultrasonography (US) is a useful diagnostic test in providing a real-time evaluation and three-dimensional view of the hip in infants less than 4 months. In infants with a normal hip ultrasound, the risk of subsequent development of hip dysplasia at an older age and the need for further follow-up is assumed to be unnecessary. In the present study, we report 2 cases of late presenting DDH in infant girls born breech with a previous normal hip exam and normal hip ultrasound at 6 weeks of age.

Abstract
BACKGROUND While various predictors of treatment outcome of Pavlik harness have been reported, appropriate indications for treatment and relationships between patient characteristics and outcome are unclear. The present study aimed to identify radiological predictors for successful Pavlik harness treatment of DDH at the initiation of treatment and investigate the progression of radiological characteristics after successful treatment. METHODS One-hundred-forty-two of 527 infants who visited our hospital for secondary screening of DDH were treated with the Pavlik harness. One-hundred-eight hips of 108 infants experienced successful treatment and could be followed up until 3 years of age (group S); treatment was unsuccessful within the first 2 weeks for 22 hips of 21 infants (group F). We investigated the Graf classification and radiological parameters. RESULTS We observed the ipsilateral-side measurements of distance A and B as defined by Yamamuro and Chene's method to be significantly smaller and greater, respectively, in group F compared with those of group S. Group F tended to exhibit the smaller distance A and larger distance B compared to the group S among the same Graf type. The cut-off values for successful treatment at were >7.4 mm at initiation of treatment for distance A and <11.2 mm for distance B. The acetabular index (AI) of the ipsilateral side at the initiation of treatment was significantly correlated with that at 1 and 3 years of age. Patients with an AI of >32° at the initiation of harness treatment were more likely to exhibit hip dysplasia at 3 years of age. CONCLUSIONS Radiographic parameters prior to the Pavlik harness could be predictors of treatment failure and DDH in the future. This study showed that AI at the initiation of treatment is associated with residual acetabular dysplasia, suggesting that radiographic assessment may be useful even considering the risks associated with radiation exposure.

Abstract
(1) Background: The prevention of critical situations is a key ability in medicine. Hip ultrasound for neonates is a standard procedure to prevent later critical outcomes, such as hip dysplasia. Additionally, the SARS-CoV-2 pandemic has put worldwide stress upon healthcare units, resulting often in a lack of sufficient medical personnel. This work aims to develop solutions to ease and speed up the process of coming to a correct diagnosis. (2) Methods: Traditional medical procedures are envisaged, but they are enhanced to reduce diagnosing errors due to the movements of the neonates. Echographic noise filtering and contrast correction methods are implemented the Hyperanalytic Wavelet Transform, combined with an adaptive Soft Thresholding Filter. The algorithm is tailored to infants’ structure and is tested on real ultrasounds provided by the “Victor Babes” University of Medicine and Pharmacy. Denoising and contrast correction problems are targeted. (3) Results: In available clinical cases, the noise affecting the image was reduced and the contrast was enhanced. (4) Discussion: We noticed that a significant amount of noise can be added to the image, as the patients are neonates and can hardly avoid movements. (5) Conclusions: The algorithm is personalized with no fixed reference value. Any device easing the clinical procedures of physicians has a practical medical application.

Abstract
PURPOSE OF REVIEW Many aspects of developmental hip dysplasia (DDH) care and evaluation are still active areas of debate. Recent studies have provided more insight into these topics such as strategies for reducing osteonecrosis, assessing hip reduction after closed and open reduction, and the management of residual acetabular dysplasia. RECENT FINDINGS The presence of the ossific nucleus at the time of reduction does not alter the risk of osteonecrosis. The risk of osteonecrosis may be higher when hips are immobilized in excessive abduction. Limited sequence MRI may be the best choice for assessing hip reduction after closed and open reduction; however, new technologies are emerging such as 3D fluoroscopy and perfusion MRI. The treatment of residual acetabular dysplasia with bracing has been shown to be effective and the decision to perform a pelvic osteotomy is based on patient-specific factors. The spectrum of DDH treatment has evolved over the past several decades. Recent studies have provided insights into strategies for osteonecrosis prevention, hip evaluation during after reduction, and the management of residual acetabular dysplasia. However, there is ample room for additional and more rigorous studies guiding advanced imaging for assessing hip reduction such as 3D fluoroscopy and perfusion MRI, as well as the management of residual acetabular dysplasia.

Abstract
Background This study investigated the association between early Graf classification and femoral head coverage (FHC) with the acetabular index (AI) at the age of 6 months. Methods A prospective observational study was conducted between 2017–2018. Patients requiring Pavlik harness treatment and patients with syndromic dislocation or neurogenic dislocation were excluded. In total, 169 newborns with the first ultrasound performed at the mean age of 12.3 (0–15) days, the second ultrasound performed at the mean age of 3.2 (2.5–4.1) months, and the AI measured at the age of 6.6 (4.3–7.1) months were enrolled. The correlation between the AI and first and second alpha angles and FHC measurements, and the correlation of dysplasia in early ultrasound with dysplasia in the AI were analyzed. Results At the first ultrasound, only the FHC (P = .02) demonstrated a significant negative correlation with the AI. At the second ultrasound, both the alpha angle (P < .01) and FHC (P < .01) demonstrated a significant negative correlation with the AI. With the AI as a reference, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were found to be 77%, 7%, 5%, and 81%, respectively, for the first Graf; 91%, 37%, 9%, and 98%, respectively, for the first FHC measurement; 82%, 90%, 35%, and 99%, respectively, for the second Graf; and 95%, 97%, 68% and 99%, respectively, for the second FHC measurement. Conclusions FHC and alpha angle exhibited significant negative correlations with the AI at six months, both ultrasound parameters may have the potential to predict AI in DDH screening. Compared to the ultrasound measurements taken at 2 weeks, Graf and FHC at 3 months demonstrated superior sensitivity, specificity, PPV, and NPV to detect abnormal AI. The best timing to perform ultrasound examination may need further research.

Abstract
BACKGROUND Breech presentation is one of the most important risk factors for developmental dysplasia of the hip, and all breech infants should be screened. The necessity of further follow-up of developmental dysplasia of the hip after normal clinical and sonographic screening is a controversial subject. The purpose of this study to identify the incidence of delayed dysplasia in breech infants after normal ultrasound screening and the necessity of further clinical and radiologic follow-up in these patients. METHODS We included the 292 breech babies (128 boys and 164 girls) who showed normal hip ultrasound screening results. To determine the incidence of delayed radiographic dysplasia, anteroposterior hip radiographs were taken between 12 and 24 months of age to measure the acetabular index (AI). RESULTS The mean AI values were 22.8±3.4 in boys and 24.9±3.1 in girls. Applying the Tönnis criteria, 29 patients (9.9%) were considered to have delayed radiographic dysplasia (16 boys and 13 girls). No significant difference was found in any demographic variables between babies with and without delayed radiographic dysplasia. None of these 29 infants underwent any treatment for radiographic dysplasia. Applying Kuong's criteria to 292 infants, only 2 patients (0.7%) demonstrated radiographic dysplasia on the hip anteroposterior radiographs taken at 14 months. CONCLUSIONS The incidence of radiographic dysplasia significantly varied depending on which criteria were applied. In order to find out more accurate incidence rates of delayed radiographic dysplasia, large-scale studies of the normative AI data for Korean infants are required. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
Hip dysplasia (HD) is common in both humans and dogs. This interconnection is because humans and dogs descended from a common ancestor and therefore have a similar anatomy at micro- and macroscopic levels. Furthermore, dogs are the animals of choice for testing new treatments for human hip dysplasia and orthopedic surgery in general. However, little literature exists comparing HD between the two species. Therefore, the aim of this review is to describe the anatomy, etiology, pathogenesis, diagnostics, and treatment of HD in humans and dogs. HD as an orthopedic condition has many common characteristics in terms of etiology and pathogenesis and most of the differences can be explained by the evolutionary differences between dogs and humans. Likewise, the treatment of HD shows many commonalities between humans and dogs. Conservative treatment and surgical interventions such as femoral osteotomy, pelvic osteotomy and total hip arthroplasty are very similar between humans and dogs. Therefore, future integration of knowledge and experiences for HD between dogs and humans could be beneficial for both species.

Abstract
Introduction: The management of developmental dysplasia of the hips (DDH) type Graf IIa is still controversial. This study aims to examine the outcomes of ultrasound-monitored Pavlik harness treatment, as well as the effects of associated factors, such as gender, side of DDH, the age at the treatment start, and laterality on the treatment outcomes in different Graf type II subtypes. Methods: A cohort retrospective investigation was performed on 88 ultrasound-screened infants or 125 hips diagnosed with Graf type II dysplasia during a six-month period at a single institution, the University Clinic for Orthopedic Surgery, Skopje. Subsequently, 47 infants (18 boys, 29 girls) or 73 hips who underwent Pavlik harness treatment with at least one follow-up throughout treatment monitoring were included in this study. Results: The treatment success rate of the right DDH Graf type IIa (-) was higher (70.8%) compared to the rate of success (50%) in the treatment of left Graf type IIa (-) hips. The mean age of the infants at the treatment start in successfully treated Graf type IIa (-) hips was lower (9.12 ± 2.27 weeks) compared to the age of the infants with treatment failure at the last follow-up (11.33 ± 3.06 weeks), P = 0.04. Conclusion: The age of treatment initiation and the side of DDH were the most relevant factors related to the treatment outcome. Infants with maturational deficit hips, Graf type IIa (-), should undergo early initiated, carefully guided, and monitored Pavlik harness treatment.

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
Background: Developmental dysplasia of the hip (DDH) is classified as a group of malformations, varying from abnormal acetabulum (dysplasia) and mild subluxation of the femoral head to fixed displacement (congenital dislocation). This study aimed to assess the knowledge level and its determinants regarding DDH in children among pregnant females in the Aseer region of southwestern Saudi Arabia. Methods: A descriptive cross-sectional study was conducted targeting all pregnant females in the Aseer region between 1 February 2021 and 1 May 2021. A pre-structured online questionnaire was constructed by the researchers to obtain the participating females’ bio-demographic data (including age, education status, and obstetric history) and awareness regarding DDH. The last section asked for their source of information regarding DDH. Results: A total of 253 pregnant females (aged between 18 and 45 years; mean age = 30.5 ± 10.2 years) fulfilling the inclusion criteria completed the study questionnaire. About 5% of the females reported having a child with DDH, and 166 (65.6%) pregnant females knew about DDH. Additionally, 110 (43.5%) females reported that they know about how DDH is treated, and 99 (39.1%) knew about DDH complications. The most commonly reported source of information was relatives and friends (44.3%), followed by social media (11.9%) and study and work (7.1%). Conclusions: Pregnant females in the Aseer region have poor knowledge and awareness about DDH and its causes, treatment modalities, and complications. Higher knowledge was associated with either high parity or having a child with DDH.

Abstract
Aims Developmental dysplasia of the hip (DDH) is a complex musculoskeletal disease that occurs mostly in children. This study aimed to investigate the molecular changes in the hip joint capsule of patients with DDH. Methods High-throughput sequencing was used to identify genes that were differentially expressed in hip joint capsules between healthy controls and DDH patients. Biological assays including cell cycle, viability, apoptosis, immunofluorescence, reverse transcription polymerase chain reaction (RT-PCR), and western blotting were performed to determine the roles of the differentially expressed genes in DDH pathology. Results More than 1,000 genes were differentially expressed in hip joint capsules between healthy controls and DDH. Both gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses revealed that extracellular matrix (ECM) modifications, muscle system processes, and cell proliferation were markedly influenced by the differentially expressed genes. Expression of Collagen Type I Alpha 1 Chain (COL1A1), COL3A1, matrix metalloproteinase-1 (MMP1), MMP3, MMP9, and MMP13 was downregulated in DDH, with the loss of collagen fibres in the joint capsule. Expression of transforming growth factor beta 1 (TGF-β1) was downregulated, while that of TGF-β2, Mothers against decapentaplegic homolog 3 (SMAD3), and WNT11 were upregulated in DDH, and alpha smooth muscle actin (αSMA), a key myofibroblast marker, showed marginal increase. In vitro studies showed that fibroblast proliferation was suppressed in DDH, which was associated with cell cycle arrest in G0/G1 and G2/M phases. Cell cycle regulators including Cyclin B1 (CCNB1), Cyclin E2 (CCNE2), Cyclin A2 (CCNA2), Cyclin-dependent kinase 1 (CDK1), E2F1, cell division cycle 6 (CDC6), and CDC7 were downregulated in DDH. Conclusion DDH is associated with the loss of collagen fibres and fibroblasts, which may cause loose joint capsule formation. However, the degree of differentiation of fibroblasts to myofibroblasts needs further study. Cite this article: Bone Joint Res 2021;10(9):558–570.

Abstract
Developmental Dysplasia of the Hip (DDH) includes a broad spectrum of hip abnormalities. DDH requires early diagnosis and treatment; however, no international consensus on screening protocol and treatment is provided in the literature. Epidemiological studies are helpful to understand the national variation of a specific surgical procedure and compare it with that of other countries. Data provided by different countries could allow researchers to provide international guidelines for DDH screening and treatment. Limited data are reported regarding trends of hospitalization for DDH, and no public database is available. The purpose of this study was to estimate annual admissions for DDH in Italian patients from 2001 to 2016, based on the hospitalization reports. Data of this study were collected from the National Hospital Discharge Reports (SDO) reported at the Italian Ministry of Health. Descriptive statistical analyses were performed. From 2001 to 2016, 3103 hospitalizations for DDH were recorded in Italy, with a mean incidence of 2.33 (per 100,000 young inhabitants). Females of the 0–4 years old group represented the majority of patients hospitalized for DDH.

Kilsdonk I, Witbreuk M, Van Der Woude HJ. Ultrasound of the neonatal hip as a screening tool for DDH: how to screen and differences in screening programs between European countries. J Ultrason 2021; 21:e147-e153. [PMID: 34258040 PMCID: PMC8264809 DOI: 10.15557/jou.2021.0024] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 05/13/2021] [Indexed: 12/15/2022] Open
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
Current clinical screening for infantile hip dysplasia relies on combined Ortolani and Barlow maneuvers, which have a quoted sensitivity and specificity of 74-98 and 84-99%, respectively. Teaching this delicate physical examination maneuver is difficult as it requires a distinct tactile feel. The purpose of this study is to validate a benchtop learning grocery-bought chicken simulator model of newborn hip instability through a pre- and post-test surveys. This model of hip dysplasia uses whole chickens. A posterior capsulotomy of the chicken's hip joint was performed to create instability. Provocative maneuvers to dislocate and relocate the hip were taught by a pediatric orthopedic surgeon. All participants completed an anonymous pre- and post-training surveys. A total of 58 participants were included in the study: 10 medical students, 13 pediatric residents, 15 orthopedic residents, and 20 orthopedic or pediatric attending physicians. The pediatric residents had performed the Barlow/Ortolani tests more than the orthopedic residents (96.15 ± 83.19 vs. 37.53 ± 60.89; P = 0.01); however, fewer pediatric residents reported feeling a positive examination (31 vs. 67%). The majority of the group agreed that the simulation felt and moved like an infant's hip (3.95 and 4.13; Likert five-point scale). The participants unanimously agreed that the model could be used to teach someone new to pediatrics the basic steps of the examination (4.91; Likert five-point scale) and should be implemented in the teaching curriculum (100%). The current study validates the benchtop model in teaching the clinical steps in detecting hip dysplasia. The model improved confidence and comfort level for all participants and proved to be a valuable tool for resident education in multiple specialties. By improving education with this model, we hope to improve early identification of hip dysplasia with increased accuracy across subspecialties.

[PMID: 33596895 PMCID: PMC7890870 DOI: 10.1186/s12891-021-04065-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Accepted: 02/09/2021] [Indexed: 11/30/2022] Open
Abstract
Background To evaluate and quantify the intraoperative effect of capsulorrhaphy on the deep seating of femoral head within the acetabulum as measured by medial joint space, a surrogate measure of acetabular-head contact. Methods In order to determine the exact effect of capsulorrhaphy, we prospectively scrutinized a consecutive sample of 18 patients with unilateral dysplastic hips aging > 18 months and followed them for a period of at least 12 months. The procedure of open reduction is described in detail. Two pediatric orthopedists carried out the operations from August 2014 to January 2019 at a tertiary pediatric hospital. Intraoperatively, AP radiographs of the pelvis were obtained before and after capsulorrhaphy. The distance between the inferomedial edge of the proximal femoral metaphysis and the lateral edge of the obturator foramen was recorded. To determine if there were differences in medial joint space due to capsulorrhaphy, a generalized linear model was run on the study sample. All patients were followed for at least 12 months to determine the rate of re-dislocation. Results Mean age (±standard deviation) of the participants was 37.5 (±24.7) months. All cases underwent Salter osteotomy, 5 cases needed femoral shortening (27.8%) and none needed derotational osteotomy. Capsulorrhaphy lead to a statistically significant decrease in the mean medial joint space from 1.59 cm before (95% CI: 1.12–2.05) to 0.76 cm after (95% CI: 0.50–1.02) the capsulorrhaphy (P < 0.001). When we took the effect of age into account the corresponding figures were 1.47 (95% CI: 1.22–1.75) and 0.67 (95% CI: 0.39–0.94), respectively (P < 0.001). After follow up periods of 1 to 5.5 years, none of the patients experienced instability or re-dislocation. Conclusions Capsulorrhaphy, independently, of age was associated with a 1-cm decrease in the mean medial hip joint space and a more deeply seated femoral head. Furthermore, this study presents a successful experience with capsulorrhaphy to prevent hip instability.

Abstract
PURPOSE Developmental dysplasia of the hip (DDH) encompasses a wide pathological spectrum, from mild acetabular dysplasia to complete congenital hip dislocation at birth. Screening policies have been implemented in an effort to effectively identify and treat patients with DDH. Since 2009 there has been a national DDH programme in Chile. The current study evaluates the results of the programme in patients born between 2010 and 2015. METHODS Records of patients hospitalized from 1st January 2010 to 31st December 2019 were retrieved from national databases. Those born from 1st January 2010 to 31st December 2015 who underwent a procedure for DDH under general anaesthesia during their first five years of life were selected. Sex, first surgical procedure and age at first surgical procedure were analyzed. The incidence of DDH that required major surgical treatment was calculated. RESULTS A total of 961 children born from 1st January 2010 to 31st December 2015 underwent a procedure for DDH during their first five years of life. The number of major procedures was significantly lower than the number of minor procedures (269 vs 692). The incidence of major procedures was 0.18 per 1000 live births. Girls underwent a higher number of procedures than boys (831 vs 130), whereas 39.2% of the boys and 26.2% of the girls had major procedures. The mean age at the time of the first procedure was 15.35 months (sd 10.09; range 0.03 to 55.92 months). CONCLUSION The present study suggests that the Chilean National DDH Screening Program is an appropriate programme with substantial benefits with respect to public health. LEVEL OF EVIDENCE II.

Abstract
INTRODUCTION Trochlear dysplasia is a known risk factor for patellar dislocations yet normal trochlea development is not well described. This study will define the articular cartilage (AC) and subchondral trochlear morphology development in pediatric patients using magnetic resonance imaging (MRI) evaluation. METHODS A retrospective knee MRI review included patients aged 3 to 16 years with nonpatellofemoral-related diagnoses. International classification of diseases-9/International classification of diseases-10 codes were used to identify eligible study patients. Measurements of the trochlea were made on the basis of previously established methods using the axial MRI just distal to the physis at the deepest portion of the trochlear groove. Three linear [lateral trochlear height (LTH), medial trochlear height (MTH), and central trochlear height (CTH)] and 3 angular [sulcus angle (SA), lateral trochlear slope (LTS), and medial trochlear slope (MTS)] were made at AC and subchondral bone (SCB). The 12 measurements were made independently by 2 study authors. Inter-rater reliability was assessed using an interclass correlation coefficient for absolute agreement to the average of the scores. Trochlea measurements were summarized across age quartiles defined as first quartile (age, 5.1 to 8.3 y), second quartile (8.3 to 11.5 y), third quartile (11.5 to 14.3 y), fourth quartile (14.3to 16.9 y). Associations between age and trochlea measures were assessed using linear regression with Huber-White-adjusted SEs to account for clustering from a small number of patients (N=16) with >1 MRI. RESULTS In total, 246 knee MRIs from 230 patients were included in this study; 113 patients (51%) were female, whereas 117 (49%) were male. A total of 116 MRIs (47%) were of the left knee and 130 (53%) were right knee. The average patient age was 11.4±3.4 years. Inter-rater agreement was high across all measures with interclass correlation coefficient values >0.7. Mean values for measurements are presented by age quartiles. LTH, MTH, and CTH showed a linear increase with age (range, 2 to 2.6 cm/y; P<0.001). SA, LTS, MTS measured at AC showed no change with age (P>0.05); however, LTS and MTS measured at SCB showed significant increases with age (0.6 and 0.9 degrees/y; P<0.001), whereas SA showed a decrease with age (-1.4 degrees/y; P<0.001). There were no significant differences found in the age associations by laterality, left versus right. There were no sex differences in the age associations for SA, LTS (P>0.05); however, for MTH, LTH, and CTH, males were found to have a significantly greater growth rate (P<0.001). CONCLUSIONS This study found an increase in AC and SCB MTH, LTH, and CTH over time, as well as an increase in SCB LTS and MTS, with a decrease in SA. However, AC of the LTS and SA remained constant, with no significant change throughout growth. This normative data indicate that the LTS and SA of AC are predictors of final trochlea shape in normal development. Final trochlear morphologic development is nearly complete around age 12 years, with no significant changes occurring thereafter.

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.

Comparison of total cost and outcomes between single-stage open reduction and Pemberton periacetabular osteotomy operation and two separate consecutive operations in treatment of bilateral developmental hip dysplasia in children at walking age.

Abstract
Open reduction and Pemberton periacetabular osteotomy (PPO) is one of the most preferred techniques for the treatment of developmental hip dyslaplasia (DDH) after the walking age. Performing the surgery as a one-stage operation or two separate consecutive operations is a controversial issue. In this study, we aimed to compare the outcomes, length of hospitalization and total cost between the patients whom had single-stage open reduction and PPO or two consecutive operations due to bilateral DDH in the walking age children. One hundred thirty patients with bilateral DDH had undergone open reduction and PPO for both hips. Seventy-five patients had one-stage open reduction and PPO for both of the hips, whereas 55 patients have two separate consecutive operations. Total time of exposure to anesthetics, blood loss and duration of operation were noted. Hospitalization period and total treatment costs were also noted for each patient. There was no statistically significant difference between the groups regarding the preoperative and postoperative AIs (P > 0.05). Comparing the total cost, length of hospitalization, exposure to anesthetics, perioperative blood loss, there was statistically significant difference between the groups (P < 0.005). Single-stage surgery had favorable outcomes. Major benefits of single-stage surgery for treatment of bilateral DDH are the reduced costs, anesthesia duration, intraoperative blood loss and hospitalization period. Also it can be presumed that prolonged immobilization can lead to loss of bone strength and resulting in fragility fractures. So single-stage open reduction and PPO for bilateral DDH can be preferred in experienced clinics.

Abstract
As one of the most frequent skeletal anomalies, developmental dysplasia of the hip (DDH) is characterized by a considerable range of pathology, from minor laxity of ligaments in the hip joint to complete luxation. Multifactorial etiology, of which the candidate genes have been studied the most, poses a challenge in understanding this disorder. Candidate gene association studies (CGASs) along with genome-wide association studies (GWASs) and genome-wide linkage analyses (GWLAs) have found numerous genes and loci with susceptible DDH association. Studies put major importance on candidate genes associated with the formation of connective tissue (COL1A1), osteogenesis (PAPPA2, GDF5), chondrogenesis (UQCC1, ASPN) and cell growth, proliferation and differentiation (TGFB1). Recent studies show that epigenetic factors, such as DNA methylation affect gene expression and therefore could play an important role in DDH pathogenesis. This paper reviews all existing risk factors affecting DDH incidence, along with candidate genes associated with genetic or epigenetic etiology of DDH in various studies.

Abstract
Chondrocyte apoptosis plays an important role in the developmental dysplasia of the hip (DDH) development. It has been found that WNT1 inducible signaling pathway protein 2 (WISP-2) and peroxisome proliferator-activated receptor γ (PPARγ) are involved in cell apoptosis. In this study, we performed the straight-leg swaddling DDH rat model and we found that cartilage degradation and chondrocyte apoptosis were remarkably increased in DDH rats in vivo. Moreover, we found that WISP-2 was upregulated in hip acetabular cartilage of DDH rats compared to control rats. Next, the effects of WISP-2 on chondrocyte apoptosis and its possible underlying mechanism were examined in vitro. The lentivirus-mediated gain- and loss-of-function experiments of WISP-2 and peroxisome proliferator-activated receptor γ (PPARγ) for cell viability and apoptosis were performed in primary rat chondrocytes. The results showed that the overexpression of WISP-2 induced chondrocyte apoptosis, and knockdown of WISP-2 could suppress the chondrocyte apoptosis induced by advanced glycation end products (AGE). Additionally, WISP-2 could negatively regulate the expression of PPARγ in chondrocytes. Moreover, the knockdown of PPARγ promoted chondrocyte apoptosis and overexpression of PPARγ abated the increased apoptosis and decreased cell viability of chondrocytes induced by WISP-2. This study demonstrated that WISP-2 might contribute to chondrocyte apoptosis of hip acetabular cartilage through regulating PPARγ expression and activation, which may play an important role in the development of DDH.

Abstract
The term ‘developmental dysplasia of the hip’ (DDH) includes a wide spectrum of hip alterations: neonatal instability; acetabular dysplasia; hip subluxation; and true dislocation of the hip. DDH alters hip biomechanics, overloading the articular cartilage and leading to early osteoarthritis. DDH is the main cause of total hip replacement in young people (about 21% to 29%). Development of the acetabular cavity is determined by the presence of a concentrically reduced femoral head. Hip subluxation or dislocation in a child will cause an inadequate development of the acetabulum during the remaining growth. Clinical screening (instability manoeuvres) should be done universally as a part of the physical examination of the newborn. After two or three months of life, limited hip abduction is the most important clinical sign. Selective ultrasound screening should be performed in any child with abnormal physical examination or in those with high-risk factors (breech presentation and positive family history). Universal ultrasound screening has not demonstrated its utility in diminishing the incidence of late dysplasia. Almost 90% of patients with mild hip instability at birth are resolved spontaneously within the first eight weeks and 96% of pathologic changes observed in echography are resolved spontaneously within the first six weeks of life. However, an Ortolani-positive hip requires immediate treatment. When the hip is dislocated or subluxated, a concentric and stable reduction without forceful abduction needs to be obtained by closed or open means. Pavlik harness is usually the first line of treatment under the age of six months. Hip arthrogram is useful for guiding the decision of performing a closed or open reduction when needed. Acetabular dysplasia improves in the majority due to the stimulus provoked by hip reduction. The best parameter to predict persistent acetabular dysplasia at maturity is the evolution of the acetabular index. Pelvic or femoral osteotomies should be performed when residual acetabular dysplasia is present or in older children when a spontaneous correction after hip reduction is not expected. Avascular necrosis is the most serious complication and is related to: an excessive abduction of the hip; a force closed reduction when obstacles for reduction are present; a maintained dislocated hip within the harness or spica cast; and a surgical open reduction.

Abstract
Background and Purpose The Salter innominate osteotomy has been an effective method to treat the developmental dysplasia of hip (DDH) over the past decades; however, several postoperative complications and deficiencies were reported. In this study, we evaluated outcome of a newly modified Salter osteotomy in patients presenting with DDH. Methods We reviewed retrospectively 76 patients (90 hips) with DDH aged ≥ 18 months, who underwent open reduction and a modified osteotomy by a single surgeon. The distal osteotomy segment of pelvis was shifted anterolaterally in the amount of osteotomy cross-section, but not downwards. The mean age at surgery was 2 years and 11 months (1.5 to 16 years). Femoral shortening was conducted when necessary. The duration of operation varied between 60 and 90 minutes. The mean follow-up was 4 years and one month (range 15 months to 7 years and 9 months). All patients were followed up both clinically (based on the modified MacKay criteria) and radiologically (based on the modified Severin criteria). Results Clinically, 94.5% of hips had excellent and good results at final follow-up, and only 5.5% had a fair condition. Radiographically, at the final follow-up 77.8% of hips were grade IA (excellent), 12.2% were grade IB, 6.7% were grade II, and 3.3% were grade III (fair). The preoperative mean acetabular index was 47.85° (41° to 59), which decreased to 17.16° (13° to 22°) immediately after the surgery (p<0.0001) and progressed to 11.24° (7° to 19°) at the final follow-up (p<0.0001). The mean initial postoperative center-edge angle was 30.3° (25° to 42°) significantly improved to 39.1 (31° to 56°) at the final follow-up (p<0.0001). Avascular necrosis of femoral head occurred in 4.4% of hips (4 patients). Conclusion The results show that our modified Salter osteotomy is safe and associated with significant benefit for the management of patients suffering from DDH.

Abstract
In dysplastic infant hips undergoing abduction harness treatment, cartilage contact pressure is believed to have a role in therapeutic cartilage remodeling and also in the complication of femoral head avascular necrosis. To improve our understanding of the role of contact pressure in the remodeling and the complication, we modeled cartilage contact pressure in cartilaginous infant hips undergoing Pavlik harness treatment. In subject-specific finite element modeling, we simulated contact pressure of normal and dysplastic hips in Pavlik harness at 90° flexion and gravity-induced abduction angles of 40°, 60° and 80°. We demonstrated that morphologies of acetabulum and femoral head both affected contact pressure distributions. The simulations showed that in Pavlik harness, contact pressure was mainly distributed along anterior and posterior acetabulum, leaving the acetabular roof only lightly loaded (normal hip) or unloaded (dysplastic hip). From a mechanobiological perspective, these conditions may contribute to therapeutic remodeling of the joint in Pavlik harness. Furthermore, contact pressure increased with the angle of abduction, until at the extreme abduction angle (80°), the lateral femoral head also contacted the posterior acetabular edge. Contact pressure in this area could contribute to femoral head avascular necrosis by reducing flow in femoral head blood vessels. The contact pressure we simulated can plausibly account for both the therapeutic effects and main adverse effect of abduction harness treatment for developmental dysplasia of the hip. © 2019 Orthopaedic Research Society.

Abstract
PURPOSE In this study the course of unstable hips after successful treatment with Fettweis plaster of Paris (POP) is examined. Special focus will be given to age at beginning of treatment and initial hip type. METHODS The development of 93 unstable hips treated between November 2001 and April 2015 was examined. Inclusion criteria were: 1) unstable hips with successful treatment with Fettweis POP; 2) presence of two pelvic radiographs (12 to 24 months and 24 to 48 months). We analyzed: 1) the initial ultrasound hip type according to Graf; 2) the average age at first and second radiograph; 3) the Tönnis classification: normal findings (< 1 SD), slightly (1 SD to 2 SD) and severely dysplastic hips (> 2 SD). RESULTS In all, there were 14 hips type D, 41 hips type III and 38 hips type IV. Mean age of the first radiograph was 13.9 months and of the second 28.5 months. The first radiograph showed: (< 1 SD): 36, (1 SD to 2 SD): 34, (> 2 SD): 23 hips, the second radiograph: (< 1 SD): 33, (1 SD to 2 SD): 19, (> 2 SD): 30 hips. With subdivision at the start of treatment at age eight or fewer weeks 2/16 hips (12.5%) and with initiation of the treatment more than eight weeks 22/77 (26.0%) deteriorated. During the course between first and second radiograph a total of 35.7% of initial hip type D, 19.5% of type III and 23.7% of type IV deteriorated. CONCLUSION Radiograph controls after treatment with Fettweis POP show poorer outcome after delaying the start of treatment more than 8 weeks. These findings were independent of the initial ultrasound hip type. Regular radiograph controls of all hip types treated for unstable hips are justified to detect residual dysplasia. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Few studies have described mobilization approaches in developmental dysplasia of the hip (DDH). The present study describes the hip mobilization of a preterm infant (born at 33 6/7 weeks of gestational age) diagnosed with DDH. DESIGN AND METHODS During the 43-day hospital stay, the infant was seen twice a week (ten sessions, 20 minutes each). All sessions included hip approximation maneuvers, with the hip positioned in abduction, lateral rotation and flexion, and lower limbs passive mobilization, which were taught to the mother. Early intervention with auditory, tactile, visual, and vestibular stimulations was also performed. The infant was assessed with hip ultrasound before and after treatment. RESULTS At 34 2/7 weeks of gestational age, she was classified as Graf IIa (left: alpha: 55°, beta: 68°; right: alpha: 59°, beta: 64°). At 40 5/7 weeks, she was classified as Graf I for left (alpha: 67°; beta: 42°) and right (alpha: 66°; beta: 42°) hips. PRACTICAL IMPLICATIONS The intervention seemed to accelerate the acquisition of stability of dysplasic hips in a preterm infant. The outcome supports further investigation of hip approximation maneuvers as part of early stimulation in preterm infants with DDH during hospital stay.

Abstract
Varus derotation femoral osteotomy (VDFO) is a commonly used surgical procedure in association with pelvic osteotomy for dislocated hip in developmental hip dysplasia. Several types of internal fixation devices were described in the literature, but none of them showed a superiority or a lower rate of complication over the others. Different types of external fixator were also described for proximal osteotomy fixation with good results. We describe the surgical technique of the VDFO using a modular external fixator with an illustrative case.

Abstract
AIM Hip dysplasia is one of the most common skeletal disorders. As a late consequence 20-25% of the patients are at risk to develop secondary osteoarthritis and may require total hip replacement early in life. The treatment principles of hip dislocation are (1) concentric reposition, (2) retention, i.e., plaster in human post or Pavlik harness and (3) maturation in abduction flexion orthesis. The Tübingen splint was introduced as a further development of abduction devices for the treatment of (residual) hip dysplasia with stable hips. The advantages are easy handling, adjustment according to growth and safe limitation of abduction. The aim of this study was to determine the success of treatment of unstable hips with use of the Tübingen splint from early diagnosis until final end of therapy hence normal ultrasound findings. METHODS From January 2003 to August 2016 79 children with 109 sonographic unstable hips were treated with the Tübingen splint initially consequently 24 h/day. Inclusion criteria were diagnosis of type D, type III a/b or type IV hips according to Graf and beginning of treatment at an age of less or equal 6 weeks, without limitation of abduction on clinical examination. RESULTS At the time of diagnosis 51 type D (46.8%), 46 type III (42.2%) and 12 type IV (11.0%) hips were noticed. In 30 patients (38.0%) bilateral hip dysplasia (type D-IV) was diagnosed. 104 of 109 hips (95.4%) treated with the Tübingen splint could be transferred in a type I hip after a mean treatment period of 88.9 days (SD ± 26.0). In 5 cases (4.6%, 1 type III and 4 type IV hips) the treatment failed. CONCLUSION Our data show, that successful treatment of unstable hips in neonates with the Tübingen splint is a comparably successful treatment modality relative to the Pavlik harness and Fettweis plaster.

Abstract
OBJECTIVE To investigate the significance of early screening of pediatric developmental dysplasia of the hip (DDH) and congenital muscular torticollis (CMT) using ultrasonography and establish a simultaneous screening model for pediatric DDH and CMT. METHODS From January, 2013 to January, 2016, a total of 5060 pediatric patients with suspected DDH and CMT underwent ultrasonic examinations. The diagnostic results of the two diseases were classified into different clinical types, and Chi-square test was used to analyze the one-way relationship between different types of DDH and CMT; correspondence analysis was used for multivariate analysis of the variables. Chi-square test was used to analyze the difference between the detection rates in suspected CMT patients and the normal population. RESULTS GrafIIa type DDH was associated with mass-type CMT in the children (χ2=331.800, P<0.001). DDH of GrafIIb, GrafIIc, Graf III, and Graf IV types were related with non-tumor type of CMT. The children with a suspected diagnosis of CMT showed a significantly higher detection rate of DDH than the normal subjects (χ2=321.889, P<0.001). CONCLUSION DDH is closely related with CMT. Early simultaneous screening of DDH and CMT can help to improve the early diagnosis rate of CMT in children.

Abstract
Developmental dysplasia of the hip (DDH) is a common condition predisposing to osteoarthritis (OA). Especially since DDH is best identified and treated in infancy before bones ossify, there is surprisingly a near-complete absence of literature examining mechanical behavior of infant dysplastic hips. We sought to identify current practice in finite element modeling (FEM) of DDH, to inform future modeling of infant dysplastic hips. We performed multi-database systematic review using PRISMA criteria. Abstracts (n = 126) fulfilling inclusion criteria were screened for methodological quality, and results were analyzed and summarized for eligible articles (n = 12). The majority of the studies modeled human adult dysplastic hips. Two studies focused on etiology of DDH through simulating mechanobiological growth of prenatal hips; we found no FEM-based studies in infants or children. Finite element models used either patient-specific geometry or idealized average geometry. Diversities in choice of material properties, boundary conditions, and loading scenarios were found in the finite-element models. FEM of adult dysplastic hips demonstrated generally smaller cartilage contact area in dysplastic hips than in normal joints. Contact pressure (CP) may be higher or lower in dysplastic hips depending on joint geometry and mechanical contribution of labrum (Lb). FEM of mechanobiological growth of prenatal hip joints revealed evidence for effects of the joint mechanical environment on formation of coxa valga, asymmetrically shallow acetabulum and malformed femoral head associated with DDH. Future modeling informed by the results of this review may yield valuable insights into optimal treatment of DDH, and into how and why OA develops early in DDH.

Abstract
BACKGROUND Many children with developmental dislocation of the hip especially in underdeveloped countries reach walking age and still remain undiagnosed, which can be detrimental to their growth and development. Because of the lack medical services often encountered in these regions, it would be attractive to find a cheap and effective treatment. Our work evaluated the results of treatment of these children by closed reduction with or without adductor tenotomy in a prospective study. METHODS We included 20 patients in this study with 29 affected hips (15 right and 14 left). Nine patients (45%) had bilateral DDH and 11 (55%) had unilateral DDH. There were 18 girls (90%) and two boys (10%) who were followed up for a mean of 21 mo (18-24 mo). Ages ranged from 9 to 36 mo (mean age 18.3 mo). Patients were divided according to age into two groups: between 9-18 mo and from 19-36 mo. The first group included nine patients (14 hips) while the second had 11 patients (15 hips). RESULTS In the first group, closed reduction failed in two patients (two hips) during the follow-up period (14.3%) and this necessitated shift to open reduction, while in the second group only one patient (bilateral DDH) had a similar failure (13.3%). We identified four hips with avascular necrosis. Three of them required no further treatment, the remaining hip was openly reduced. CONCLUSIONS Closed reduction in older children offers a valid and reproducible treatment modality in the hands of an experienced pediatric orthopaedic surgeon as long as there is close follow-up and thorough knowledge of possible complications and their management including the ability to shift timely to open reduction.

Abstract
Specialised DDH (developmental dysplasion of the hip) clinics are developing around Ireland but are, however, variable in how they are operated. A DDH clinic was set up in the South-east of Ireland in 2002 with the goal of achieving an integrated care pathway between the orthopaedic surgical team and nursing team, working to an explicit protocol while also fostering a strong collaboration with the ultrasound department. This paper aims to explore the effectiveness of this dedicated clinic in the Southeast of Ireland.

Abstract
Objective: To evaluate the knowledge on developmental dysplasia of the hip (DDH) by professionals involved in its diagnosis. Methods: This is a cross-sectional study using questionnaires to assess the knowledge about DDH. Orthopedic surgeons and pediatricians, residents and medical students from a tertiary teaching hospital were included in the study. Results: We evaluated 142 medical students, eight orthopedic residents, ten pediatric residents, seven pediatricians, and nine orthopedic surgeons; 50% declared not having examined any DDH case in the last year and only three had diagnosed more than 10 cases during their career. Regarding self-assessed knowledge (0-10), the average score was 4.25 [n=186; SD=2.43]. Nineteen percent of the participants ignored semiological tests and 26.1% of pediatricians (specialists and residents), were unaware of how to perform them. The most acknowledged and neglected risk factor was pelvic presentation (68%) and CMT (9.3%), respectively. None of the participants were able to identify all the risk factors. The average number of risk factors identified was two (n=186; SD=1.58). Forty seven point three percent of the participants failed to recognize the time of birth as the ideal moment for diagnosis; 17% reported it was after the first month. Regarding neglected severe DDH, 45.3% failed to recognize its natural history. Conclusion: Knowledge on DDH among health professionals who are involved in screening is flawed.

Abstract
The aim of the study was to assess the clinical value of ultrasound screenings for the developmental dysplasia of the hip (DDH) and explore its etiology in high-risk infants with cerebral palsy in follow-up visits. A group of 98 cases of infants at high-risk of cerebral palsy who received rehabilitation treatment between July, 2009 and July, 2010 were selected. Infants included 58 men and 40 women, aged <6 months and not lost to follow-up visits. Ultrasound (using Graf static inspection) screening of hips was performed and the infants with abnormalities were given clinical intervention, and 1- to 2-year-old infants were given outpatient follow-ups. The results were analyzed and there were 40 abnormal cases among the 98 cases of infants at high risk of cerebral palsy, including 18 cases of unstable hip joint, and 22 cases of DDH (12 cases of hip dysplasia, 3 cases of hip subluxation and 7 cases of hip dislocation). Early clinical intervention for infants with hip dysplasia and outpatient follow up for infants aged 1–2 years was carried out and had ischemic necrosis of femoral head, with the exception of 1 case of femoral detorsion that was poorly restored. In conclusion, the probability of DDH was higher in infants at high-risk of cerebral palsy compared to the normal infants. Hip ultrasound is a safe, simple, and effective screening method for these infants, which is of great clinical significance for an earlier diagnosis and treatment of DDH in infants with cerebral palsy.

Abstract
Developmental dysplasia of the hip (DDH) describes the spectrum of structural abnormalities that involve the growing hip. Early diagnosis and treatment is critical to provide the best possible functional outcome. Persistence of hip dysplasia into adolescence and adulthood may result in abnormal gait, decreased strength and increased rate of degenerative hip and knee joint disease. Despite efforts to recognize and treat all cases of DDH soon after birth, diagnosis is delayed in some children, and outcomes deteriorate with increasing delay of presentation. Different screening programs for DDH were implicated. The suspicion is raised based on a physical examination soon after birth. Radiography and ultrasonography are used to confirm the diagnosis. The role of other imaging modalities, such as magnetic resonance imaging, is still undetermined; however, extensive research is underway on this subject. Treatment depends on the age of the patient and the reducibility of the hip joint. At an early age and up to 6 mo, the main treatment is an abduction brace like the Pavlik harness. If this fails, closed reduction and spica casting is usually done. After the age of 18 mo, treatment usually consists of open reduction and hip reconstruction surgery. Various treatment protocols have been proposed. We summarize the current practice for detection and treatment of DDH, emphasizing updates in screening and treatment during the last two decades.
