Giorgi V, Apostolo G, Bertelè L. Treatment of developmental hip dysplasia with manual therapy following Pavlik harness failure: a case report with long-term follow-up. J Man Manip Ther 2024; 32:352-361. [PMID: 38706305 PMCID: PMC11216241 DOI: 10.1080/10669817.2024.2349334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 04/24/2024] [Indexed: 05/07/2024] Open
Abstract
BACKGROUND Developmental dysplasia of the hip (DDH) is a common musculoskeletal disorder in newborns, ranging from mild dysplasia to complete dislocation. Early detection and intervention are crucial for managing DDH. However, in some cases, standard orthopedic treatments such as the Pavlik harness fail, and alternative approaches are needed. Our study explores the possibility that manual therapy, specifically the Mézières-Bertelè Method (MBM), could be beneficial in cases of DDH that are resistant to conventional treatments. CASE DESCRIPTION We present a case of a 20-month-old female who had been suffering from persistent DDH (Graf's type IIIC on the left), pain and limping, despite previous conventional treatments, including the Pavlik harness. The patient received daily MBM sessions for six months, followed by maintenance sessions every two months. OUTCOMES After undergoing the MBM treatment, the patient showed clinical improvements, such as normal neuromotor development and restored hip joint parameters. We observed normal walking and running abilities, and X-ray parameters returned to normal levels. The patient sustained positive outcomes during long-term follow-up until the age of 7. CONCLUSION The MBM manual therapy was used to treat a challenging case of DDH resistant to conventional treatment. This case report suggests a possible correlation between manual therapy and improved outcomes in resistant DDH and highlights the potential relevance of addressing the inherent musculoskeletal components of the condition.

Comparison of clinical and radiological outcomes for the anterior and medial approaches to open reduction in the treatment of bilateral developmental dysplasia of the hip: a systematic review protocol. Syst Rev 2024; 13:72. [PMID: 38396003 PMCID: PMC10885537 DOI: 10.1186/s13643-023-02444-6] [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: 01/19/2023] [Accepted: 12/21/2023] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Developmental dysplasia of the hip (DDH) affects 1-3% of newborns and 20% of cases are bilateral. The optimal surgical management strategy for patients with bilateral DDH who fail bracing, closed reduction or present too late for these methods to be used is unclear. There are proponents of both medial approach open reduction (MAOR) and anterior approach open reduction (AOR); however, there is little evidence to inform this debate. METHODS We will perform a systematic review designed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocol. We will search the medical and scientific databases including the grey and difficult to locate literature. The Medical Subject Headings "developmental dysplasia of the hip", "congenital dysplasia of the hip", "congenital hip dislocation", "developmental hip dislocation", and their abbreviations, "DDH" and "CDH" will be used, along with the qualifier "bilateral". Reviewers will independently screen records for inclusion and then independently extract data on study design, population characteristics, details of operative intervention and outcomes from the selected records. Data will be synthesised and a meta-analysis performed if possible. If not possible we will analyse data according to Systematic Review without Meta-Analysis guidance. All studies will be assessed for risk of bias. For each outcome measure a summary of findings will be presented in a table with the overall quality of the recommendation assessed using the Grading of Recommendations Assessment Development and Evaluation approach. DISCUSSION The decision to perform MAOR or AOR in patients with bilateral DDH who have failed conservative management is not well informed by the current literature. High-quality, comparative studies are exceptionally challenging to perform for this patient population and likely to be extremely uncommon. A systematic review provides the best opportunity to deliver the highest possible quality of evidence for bilateral DDH surgical management. SYSTEMATIC REVIEW REGISTRATION The protocol has been registered in the International Prospective Register of Systematic Reviews (PROSPERO ID CRD42022362325).

Abstract
OBJECTIVE The Pavlik harness (PH) has been widely used as the standard treatment for infants with developmental dysplasia of the hip (DDH). When the initial application of the PH fails, alternative treatments, such as closed reduction, open reduction, and reapplication of the PH will be considered. Compared with other treatments, reapplication of the PH offers certain advantages, including simplicity and reduced physical, and psychological stress, on both infants and caregivers. This study aims to investigate the effectiveness of reapplying the PH in patients with DDH. METHODS This study included patients with DDH (complete dislocation) who were treated by reapplication of PH between 1988 and 2012. Patients who were able to follow-up for more than 5 years were included. We examined the reduction rate and several factors to identify indicators associated with successful reduction during reapplication, including age, sex, side of hip dislocation, and the presence of the Ortolani sign. At the final follow-up, hip development was assessed using the Severin classification, whereas avascular necrosis (AVN) was evaluated using the Kalamchi classification and the Salter criteria. RESULTS A total of 56 patients (48 females and 8 males) and 57 hips were included in this study. The mean age at first and second application of PH was 4.2 months old (range: 0.12 to 6.4), and 5.8 months old (3.0 to 11.4), respectively. The reduction rate was 49% (28 out of 57 hips). Among the successfully reduced hips, the AVN rate was 3.6% (1 out of 28 hips). The Severin classification revealed 27 hips in class I and 1 hip in class III. Statistical analysis indicated a significantly higher proportion of left hip involvement in the reduction group (85% vs 41%, χ 2 test, P < 0.001). Although not statistically significant, the rate of positive Ortolani sign tended to be higher in the reduction group (61% vs 38%, χ 2 test, P = 0.06). CONCLUSION The reapplication method demonstrated a 49% reduction rate and a low AVN rate of 3.6% in our study. It is worth considering for patients who fail the initial PH treatment, particularly in cases of left-side dislocation and a positive Ortolani sign during the initial application.

Abstract
BACKGROUND Established associated factors for DDH include female sex, breech presentation, family history, congenital malformations, oligohydramnios, and maternal hyperthyroidism. However, evidence for environmental factors that may contribute to DDH is limited and inconsistent. METHODS A systematic review of medical literature was conducted to collect data on environmental factors, including latitude, longitude, average yearly precipitation, average yearly temperature, minimum monthly temperature, and maximum monthly temperature, from all institutions that published articles on DDH. Univariate linear regression analysis was used to examine the correlation between environmental factors and DDH incidence, while multiple regression analysis was conducted to identify significant associated factors for DDH incidence. RESULTS Data from a total of 93 unique manuscripts were analyzed, revealing a significant negative correlation between DDH incidence and temperature, including average yearly temperature (r = -0.27, p = 0.008), minimum monthly temperature (r = -0.28, p = 0.006), and maximum monthly temperature (r = -0.23, p = 0.029). Additionally, there was a significant positive correlation between DDH incidence and latitude (r = 0.27, p = 0.009), and a significant negative correlation between DDH incidence and average yearly precipitation (r = -0.29, p = 0.004). In the final multiple regression analysis, temperature, including average yearly temperature, minimum monthly temperature, and maximum monthly temperature, were identified as significant associated factors for DDH incidence. CONCLUSION The findings of this study suggest an association between cold weather and DDH incidence. Further research should explore the link between cold weather and DDH incidence, offering insights into potential interventions for cold climates.

Acetabular index as an indicator of Pavlik harness success in grade I developmental dysplasia of the hip: A retrospective study. J Child Orthop 2023; 17:598-606. [PMID: 38050594 PMCID: PMC10693839 DOI: 10.1177/18632521231199519] [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: 01/19/2023] [Accepted: 08/16/2023] [Indexed: 12/06/2023] Open
Abstract
Purpose Some articles have focused on the effectiveness of the Pavlik harness treatment for unstable and dislocated hips, yet data on monitoring its effectiveness with the acetabular index remains elusive. Therefore, this study aimed to assess Pavlik harness effectiveness in infants ≤6 months diagnosed with grade I developmental dysplasia of the hip using acetabular index improvement and identify the possible predictors of successful Pavlik harness treatment. Methods A retrospective review of infants with grade I acetabular dysplasia treated with a Pavlik harness and monitored with anteroposterior pelvis X-rays at presentation and follow-up. Successful treatment was defined as achieving an acetabular index <30°. Results A total of 231 infants with acetabular dysplasia were treated with a Pavlik harness. A successful outcome was achieved in 135 infants (58.4%). Younger age, lower initial acetabular index, and patients with unilateral developmental dysplasia of the hip were significant predictors of a successful outcome. An age of 4.5 months or older was found to be the threshold for an unsuccessful result following Pavlik harness treatment, with a sensitivity of 65.2% and specificity of 57.3%. An initial acetabular index of 35.5° was found to be the threshold for an unsuccessful result, with a sensitivity of 83.7% and specificity of 61.5%. Conclusion Pavlik Harness's success in correcting the acetabular index in acetabular dysplasia patients was related to unilateral cases, a younger age at presentation, and a lower initial acetabular index. The thresholds for unsuccessful treatment were an age of 4.5 months or greater and an acetabular index of 35.5° or higher.

Abstract
Objectives The aim of this study was to report the incidence of femoral nerve palsy in developmental dysplasia of the hip children treated with Pavlik harness, to identify any possible associated risk factors, and to evaluate its outcome without any specific strap release. Methods A retrospective chart review was conducted on all cases of femoral nerve palsy in a consecutive series of children who underwent Pavlik harness treatment for developmental dysplasia of the hip. In unilateral cases, the developmental dysplasia of the hip was compared to the contralateral side. All hips with femoral nerve palsy were compared to the remaining hips of the series and any possible risk factor for paralysis was recorded. Results In total, 53 cases of femoral nerve palsy of various severity were identified from a group of 473 children with 527 hips treated for developmental dysplasia of the hip at an average age of 3.9 months. However, 93% occurred during the first 2 weeks of treatment. Femoral nerve palsy was more common in older and larger children with the most severe Tonnis type, and a hip flexion angle in the harness above 90° (p < 0.03 for all). All of them resolved spontaneously before completion of treatment without any specific measures. We found no correlation between the presence of femoral nerve palsy or the time taken for spontaneous resolution and treatment failure using the harness. Conclusion Femoral nerve palsy is most observed with higher Tonnis types and high hip flexion angles in the harness, but its presence by itself is not predictive of treatment failure. It resolves spontaneously before completion of treatment and does not require any strap release or harness discontinuation. Level of evidence Level III.

Known risk factors of the developmental dysplasia of the hip predicting more severe clinical presentation and failure of Pavlik harness treatment. BMC Pediatr 2023; 23:148.

Abstract
PURPOSE Developmental dysplasia of the hip (DDH) varies from mild instability of the hip to subluxation or total dislocation of the joint. Well-known risk factors of DDH include pre-natal breech position, female sex, positive family history, hip side, primiparity and the mode of delivery. Aim of the present study was to further evaluate known risk-factors of DDH, find associations with more severe dysplasia (characterized with Ortolani positivity) and find risk factors of failure of the Pavlik harness treatment. MATERIAL AND METHODS All children with the diagnosis of DDH treated in Tampere University hospital in the years 1998-2018 were retrospectively identified for the study and the data was collected from the medical records. Teratological dislocations (n = 3) were excluded from the analysis. Total of 945 patients were included. RESULTS Breech presentation was strongly associated with Ortolani positivity (p < 0.001). Breech presentation was not associated with ending up for spica casting and/or operative treatment (p = 0.291) despite the association with Ortolani positivity. Ortolani positivity (p = 0.002), positive family history (p = 0.013) and girl sex (p = 0.029) were associated with ending up for spica casting and/or operative treatment. CONCLUSION Breech presentation seems to increase the risk of Ortolani positive DDH. However, these infants are likely to recover with initially started Pavlik harness treatment, as it was not associated with elevated risk for undergoing more robust treatments. Positive family history and girl sex are associated with the most severe cases of developmental dysplasia of the hip, and it may predispose to the failure of the Pavlik harness treatment.

J Orthop Sci 2022; 27:1067-1072.

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
PURPOSE To investigate the impact of failed Pavlik harness (PH) treatment on the outcomes following closed reduction (CR) or open reduction (OR) in developmental dysplasia of the hip (DDH). METHODS Ninety-three DDH patients treated with CR or OR were enrolled. One group of which received previous PH treatment (F group) and the other (L group) not. The clinical outcomes were evaluated according to McKay's criteria. Radiographs were evaluated for acetabular index (AI) and the degree of dislocation of the hips. RESULTS A higher rate of CR was found in F group (P = 0.034). Before CR/OR, the mean AI in F group was significantly lower than that in L group (P = 0.000), while at the last follow-up, the AIs in both groups were all improved. In F group, there were 7 (16.67%), 18 (42.86%) and 17 (40.48%) hips were classified as Graf type II, III and IV pathologic changes, respectively, when PH treatment started, while the corresponding data were 17 (40.48%), 17 (40.48%) and 8 (19.05%) after PH treatment (P = 0.024). At the last follow-up, no significant difference was found concerning the complications between the two groups (P > 0.05). CONCLUSIONS PH treatment, even if failed, may have the ability of accelerating the development of the acetabulum and increasing the rate of successful CR. Thus we advocate a trial of PH treatment for all DDH patients less than 6 months of age. Meanwhile, a close monitoring by dynamic ultrasonography is required due to the risk of AVN.

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 Pavlik harness (PH) treatment is successful in treating over 90% of newborns with developmental dysplasia of the hip (DDH). There is a need for close supervision, frequent adjustments, size changes, and monitoring of complications. This paper aims to provide a safe criterion for remote follow-up of DDH patients treated in a PH to reduce the risk of COVID-19 (coronavirus disease 2019) exposure to patients, parents, and health practitioners. METHODS All infants with stable hips (Graf I, IIa/b/c/d, treated III/IV) with consenting parents after appropriate counseling were enrolled in a virtual clinic. Clinics were conducted using the NHS "Attend anywhere" virtual link service by an extended scope practitioner-specialist physiotherapist and a clinical nurse specialist. The virtual clinic group was compared with a matched cohort of patients from 2018/2019. RESULTS A total of 141 patients were referred to the neonatal hip clinic; 45 patients were eligible for harness treatment and 20 patients were selected for virtual clinics. In total, there were 35 virtual clinic appointments. Each of the patients had an average of 1.7 virtual appointments ranging from 1 to 3 (26.3% of total number of clinics). Age at presentation of the treated group was 7±4.2 weeks and control group 5.7±5.5 weeks (P=0.59). PH duration of the study group was 9±2.6 weeks and the control group, 7.8±2.5 weeks (P=0.12). There were no missed complications at the follow-up face-to-face appointment. Patients saved an average of 76 km total travel distance. CONCLUSIONS This study demonstrates adequate evidence that children requiring routine follow-up appointments involving PH adjustment, skincare, and identification of clinical anomalies, can be treated and followed up safely using virtual clinics. Clinical triage of suitable patients for virtual clinic provision must always be made by experienced clinicians. Children presenting with Graf IIa, IIb, IIc, IId, as well as those with stable and improving Graf III at initial diagnoses, had successful treatment with virtual clinic follow-up appointments in this study.

Abstract
PURPOSE A consistent relationship between CMT and DDH has been established. However, whether the presence of CMT has effect on clinical outcomes of DDH remains unanswered. This study aimed to evaluate clinical features and management of DDH in patients with CMT. METHODS We reviewed the medical records of 54 patients (91 hips) simultaneously diagnosed with DDH and CMT and included 54 patients (97 hips) with only DDH by random number method as the control group. Clinical and examination outcomes were recorded and compared, respectively. RESULTS The mean follow-up was 18.1 ± 14.5 months (range, 2 to 72 mo). In the DDH and CMT group, the age of initial treatment was lower (100.8 ± 92.3 vs. 229.0 ± 157.4 d, P < 0.001), and the rate of male significantly increased (42.6% vs. 11.1%, P < 0.001). Before treatment, development degree of hip was better than that of the DDH group. Therefore, patients with CMT had approximately 14 times greater odds of conservative treatment success than children in the DDH group (OR, 13.84; 95% CI, 3.16 to 60.60). CONCLUSION We concluded that CMT was not the risk factor for the failure of treatment. On the contrary, the identification of CMT may be beneficial to early discovery and treatment of DDH when we remain vigilant to perform physical exam and screen imaging of DDH for patients with CMT.

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
PURPOSE This study aimed to explore the docking of the femoral head into the acetabulum after gradual reduction (GR) using traction for developmental dysplasia of the hip (DDH) and the impact on subsequent acetabular development. METHODS A total of 40 patients with DDH (42 hips) undergoing GR using overhead traction and spica casting were retrospectively reviewed. The presence of inverted labrum and the coronal and axial femoral-acetabular distances (FADs) were compared between MRI immediately and five weeks after spica casting. The change in the acetabular index on anteroposterior pelvic radiographs were compared between hips with inverted labrum (residual group) and with normally-shaped labrum (normalized group) on follow-up MRI. RESULTS The mean age at reduction was 13.1 months (7 to 33) and the mean follow-up duration was 7.7 years (4 to 11). The rate of inverted labrum and the FADs significantly decreased between the MRI scans (all p-values < 0.001), and previous Pavlik harness failure had no negative effect on these decreases. The acetabular indices at the ages of three and five years in the residual group were significantly larger than those in the normalized group (both p-values < 0.001). Residual acetabular dysplasia was seen in 84.2% of the residual group compared with 34.8% of the normalized group (p = 0.002). CONCLUSION The docking phenomenon can occur during spica casting following GR using traction in children with DDH between the ages of six months and three years. The remaining inverted labrum at the cast removal may negatively affect subsequent acetabular development. LEVEL OF EVIDENCE III - retrospective comparative study.

Abstract
Bracing is considered a gold standard in treating Developmental Dysplasia of the Hip (DDH) in infants under 6 months of age with reducible hips. A variety of braces are available that work on similar principles of limiting hip adduction and extension. This paper summarises the current evidence regarding bracing in DDH. Most of the literature pertains to the Pavlik harness (PH) and there are few studies for other brace types. Bracing eliminates dislocating forces from the hamstrings, the block to reduction of the psoas and improves the muscle line of pull to stabilise the hip joint. Recent studies have shown no benefit in bracing for stable dysplasia. The rates of PH treatment failure in Ortolani-positive hips have been reported to be high. Barlow positive hips have lower Graf grades and are more amenable to PH treatment. There is consensus that the earlier the diagnosis of DDH and initiation of PH treatment, the better the outcome. Failure rates due to unsuccessful reduction and AVN are higher with treatment initiated after age 4-6 months. Studies have shown no benefits of staged weaning of braces. While there is no maximum time in brace, current consensus suggests a minimum of 6 weeks. The key to successful bracing lies in education and communication with the family.

Abstract
PURPOSE To investigate the success rate of the Tübingen hip flexion splint (THFS) for the treatment of developmental dysplasia of the hip (DDH), of different severity as per the Graf classification, among infants younger than six months of age. The type and incidence rate of complications associated with THFS treatment were also evaluated. METHODS The following databases were searched using keywords and limited for age less than six months: PubMed, Embase, Web of Science, Cochrane Library, and SinoMed, between inception and July 2020. Articles were screened and extracted by two researchers, and the quality of the included literature was evaluated (methodological index for non-randomized studies criteria). R studio 1.3 was used for statistical analysis. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS After screening, eight articles were included in the analysis, contributing 1211 hips (875 patients). The overall success rate of THFS treatment is 91% (95% confidence interval (CI) 0.82 to 0.95). The success rate by Graf type is as follows: type-II, 98% (95% CI 0.94 to 1.00); type-III, 96% (95% CI 0.88 to 1.00); and type-IV, 32% (95% CI 0.18 to 0.47). Complications (24/1211, 2%) included transient femoral nerve palsy (n = 1); avascular necrosis of the femoral head (n = 9) and residual acetabular dysplasia (n = 14). CONCLUSION THFS treatment is successful for Graf type-II and -III, but low for type-IV, with a low rate of complication. THFS may be an effective treatment option for DDH among infants less than six months of age. However, those with Graf type-IV require close monitoring. LEVEL OF EVIDENCE III.

Abstract
Developmental dysplasia of the hip (DDH) encompasses a wide spectrum of hip disorders, including neonatal instability, acetabular dysplasia, hip subluxation, and frank dislocation of the hip. It is a common disorder, with a reported incidence of between 0.1% and >10% of live births.
Coordinated, interdisciplinary care is important to achieving successful outcomes. This starts with accurate assessment of risk factors in the prenatal period, thorough clinical examination by the primary care provider at all well-child visits, and early referral to a pediatric orthopaedic surgeon for prompt diagnosis and treatment. Early diagnosis and prompt treatment is critical for an excellent outcome. Ongoing, open communication between clinicians is essential for the effective coordination of care. Treatment options vary depending on the age of presentation. A Pavlik harness (dynamic hip abduction orthosis) is used for children up to 6 months of age. A more rigid abduction orthosis may be used if treatment with a Pavlik harness is unsuccessful, with a closed reduction and spica cast being the next step if needed for children up to 18 months of age. Finally, open reduction with possible concomitant femoral and/or pelvic osteotomies is the surgical option in an older child, when necessary. In general, the later the child is diagnosed with and treated for DDH, the greater the risk of a nonoptimal outcome. Depending on the severity of the condition, children with DDH may need to be followed closely until skeletal maturity so as not to miss the diagnosis of asymptomatic residual hip dysplasia, which can predispose patients to early hip arthritis.

Abstract
Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (<2500 g [5.5 lb]) and 10% were born preterm (gestational age of <37 completed weeks). Many of these infants and others with congenital anomalies, perinatally acquired infections, and other disease require admission to a NICU. In the past decade, admission rates to NICUs have been increasing; it is estimated that between 10% and 15% of infants will spend time in a NICU, representing approximately 500 000 neonates annually. Approximately 3600 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome International Classification of Diseases, 10th Revision (R95), ill-defined deaths (R99), and accidental suffocation and strangulation in bed (W75). Preterm and low birth weight infants are particularly vulnerable, with an incidence of death 2 to 3 times greater than healthy term infants. Thus, it is important for health care professionals to prepare families to maintain their infant in a safe sleep environment, as per the recommendations of the American Academy of Pediatrics. However, infants in the NICU setting commonly require care that is inconsistent with infant sleep safety recommendations. The conflicting needs of the NICU infant with the necessity to provide a safe sleep environment before hospital discharge can create confusion for providers and distress for families. This technical report is intended to assist in the establishment of appropriate NICU protocols to achieve a consistent approach to transitioning NICU infants to a safe sleep environment as soon as medically possible, well before hospital discharge.

Abstract
BACKGROUND Frankly dislocated hips occur in ∼1% to 3% of infants with developmental dysplasia of the hip and are often difficult to treat. In the most severely dislocated hips, the femoral head is positioned outside the posterior/lateral rim of the acetabulum and is irreducible, that is, the femoral head will not reduce by positioning the leg. The purpose of this study was to determine risk factors, using univariate and multivariate analyses, for Pavlik harness failure in infants who initially presented with irreducible/dislocated hips (confirmed by dynamic sonography). METHODS Following institutional review board approval, 124 infants (170 hips) with frankly dislocated hips treated using a Pavlik harness between 2000 and 2018 were evaluated. Patients' demographic characteristics, clinical findings, dynamic sonographic findings (dislocated-fixed vs. dislocated-mobile), age at onset of Pavlik harness treatment, duration of harness usage, and follow-up treatments were recorded. Univariate analyses were used to determine risk factors for treatment failure. RESULTS In frankly dislocated hips (confirmed by dynamic sonography to be positioned outside the posterior/lateral rim of the acetabulum), Pavlik harness treatment was successful in 104 of 170 hips (61%) while it failed in 66 hips. Mean follow-up was 4.86±4.20 years. Univariate analysis determined the risk factors to be onset of treatment after the seventh week of age (P=0.049) and initial mobility (dislocated-fixed group) (P<0.001) by dynamic sonography. In addition, multivariate analysis (P=0.007) showed infants of multigravida mothers (non-firstborn) to be another risk factor for failure. Six percent of hips with no risk factors failed Pavlik harness treatment, those with 1 risk factor had 42% failure, 2 risk factors had 69% failure, and all 3 risk factors had 100% failure. CONCLUSIONS In our patients with frankly dislocated irreducible hips, 39% of hip failed Pavlik harness treatment. Independent multivariate, logistic regression analysis, and multivariate analysis determining the risk factors for failure of Pavlik harness treatment were onset of treatment after the seventh week of age, infants of multigravida mothers, and initial hip mobility (fixed-dislocated hips) by dynamic sonography.

Abstract
Infant positioning in daily life may affect hip development. While neonatal animal studies indicate detrimental relationships between inactive lower extremities and hip development and dysplasia, no research has explored infant hip biomechanics experimentally. This study evaluated hip joint position and lower extremity muscle activity of healthy infants in common body positions, baby gear, and orthopedic devices used to treat hip dysplasia (the Pavlik harness and the Rhino cruiserabduction brace). Surface electromyography(EMG) and marker-based motion capture recorded lower extremity muscle activity and kinematics of 22 healthy full-term infants (4.2±1.6 months, 13M/9F) during five conditions: Pavlik harness, Rhino brace, inward-facing soft-structured baby carrier, held in arms facing inwards, and a standard car seat. Mean filtered EMG signal, time when muscles were active, and hip position (angles) were calculated. Compared to the Pavlik harness, infants exhibited similar adductor activity (but lower hamstring and gluteus maximus activity) in the Rhino abduction brace, similar adductor and gluteus maximus activity (but lower quadriceps and hamstring activity) in the baby carrier, similar but highly variable muscle activity in-arms, and significantly lower muscle activity in the car seat. Hip position was similar between the baby carrier and the Pavlik harness. This novel infant biomechanics study illustrates the potential benefits of using inward-facing soft-structured baby carriers for healthy hip development and highlights the potential negative impact of using supine-lying container-type devices such as car seats for prolonged periods of time. Further study is needed to understand the full picture of how body position impacts infant musculoskeletal development.

Abstract
BACKGROUND Developmental dysplasia of the hip (DDH) is one of the most common pediatric conditions. The current gold-standard treatment for children under six months of age with a reducible hip is bracing, but the orthopedic literature features several splint options, and each one has many advantages and disadvantages. The aim of this review is to analyze the available literature to document the up-to-date evidence on DDH conservative treatment. METHODS A systematic review of PubMed and Science Direct databases was performed by two independent authors (C.d.C. and A.V.) using the keywords "developmental dysplasia hip", "brace", "harness", "splint", "abduction brace" to evaluate studies of any level of evidence that reported clinical or preclinical results and dealt with conservative DDH treatment. The result of every stage was reviewed and approved by the senior investigators (V.P. and G.T.). RESULTS A total of 1411 articles were found. After the exclusion of duplicates, 367 articles were selected. At the end of the first screening, following the previously described selection criteria, we selected 29 articles eligible for full text reading. The included articles mainly focus on the Pavlik harness, Frejka, and Tubingen among the dynamic splint applications as well as the rhino-style brace, Ilfeld and generic abduction brace among the static splint applications. The main findings of the included articles were summarized. CONCLUSIONS Dynamic splinting for DDH represents a valid therapeutic option in cases of instability and dislocation, especially if applied within 4-5 months of life. Dynamic splinting has a low contraindication. Static bracing is an effective option too, but only for stable hips or residual acetabular dysplasia.

Abstract
BACKGROUND Closed reduction is generally attempted on children under 18 months of age who present as older infants or who fail nonoperative management for developmental dysplasia of the hip (DDH). However, many of these patients will not achieve concentric reduction by closed means and will ultimately require open reduction (OR). Limited evidence exists to predict which patients can be adequately closed reduced versus those who will need open treatment. METHODS Prospectively collected data from 4 select centers of an international multicenter study group sharing a common treatment approach were reviewed for all DDH infants under 18 months old that required operative management. Patients were categorized into 2 groups: those whose hips were successfully closed reduced or those who ultimately required OR. Factors were compared between the closed reduction and OR groups for 2 separate cohorts-those presenting early in life with ultrasound (US) data, and those presenting later with radiographic data. RESULTS A total of 154 patients (166 hips) were included in the analysis. Overall, 87.3% were female. In the early-presenting cohort, purposeful entry multivariate regression revealed that patients with Graf IV hips on US had 3.8 times higher odds of requiring an OR. For the later cohort, hips that were clinically irreducible (ie, negative Ortolani sign) had 3.3 times higher odds of requiring OR. Patients with International Hip Dysplasia Institute (IHDI) grade IV hips had 2.5 times higher odds of needing an OR versus those with grade III hips and 15.4 times higher odds than those with grade II hips. Children with an IHDI grade IV hip and a negative Ortolani sign had 4.4 times higher odds of needing OR. CONCLUSION Children younger than 18 months with dislocated hips who require OR are more likely to have a high-grade radiographic dislocation (IHDI grade IV), negative preoperative Ortolani sign, and a Graf IV classification on initial US. This information may help surgeons budget the use of operating room time and better counsel parents about intraoperative expectations. LEVEL OF EVIDENCE Level III-Prognostic.

Abstract
BACKGROUND Developmental dysplasia of the hip is effectively treated with a Pavlik harness (PH) within the first 6 months of life. Over 80% of unstable hips in the newborn period will naturally stabilize by 2 months of age. If there is no difference in the effectiveness of initiating PH treatment at 1 week compared with 4 weeks of age, waiting may allow the hips to naturally stabilize and avoid treatment. The purpose of this study is to evaluate whether the timing of PH implementation influences its effectiveness in the treatment of developmental dysplasia of the hip. METHODS A retrospective review was conducted between 2004 and 2010. Patients were included if PH therapy was prescribed for hip instability or dislocation at or before 6 months of age. PH failure was defined as requiring any operative procedure for definitive management. Groups were divided based on the age at which the PH was initiated-group1=<30 days, group 2=30 to 60 days, group 3=>60 days. RESULTS A total of 176 children were included with 38 (21.6%) failing PH treatment. The mean age at PH initiation was 1.3 months (SD=1.3) in the successfully treated children and 1.4 months (SD=1.2) in the failures (P=0.77). There was no difference in the failure rates by age with group 1=19.1% (18/94), group 2=22.5% (9/40), and group 3=26.2% (11/42) (P=0.87). There was no statistical difference with respect to sex or breech positioning in the success or failure groups; however, there was a higher percentage of bilateral involvement in the failure group (P=0.04). CONCLUSIONS Patients who had PH initiation before 30 days of age were no more or less likely to fail than when PH was initiated after 30 days of age. Parents can be counseled that waiting until after 30 days of age is appropriate before PH implementation. By avoiding swaddling during this period, the hips may stabilize without treatment and allow for more parental-infant bonding before implementation of PH. LEVEL OF EVIDENCE Level III-therapeutic, case control study.

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
PURPOSE The aim of this article is to review the current concepts in the indications, results and failure causes of the treatment of developmental dysplasia of the hip (DDH) with the Pavlik harness. METHODS The reported variables influencing the outcome in the Pavlik harness treatment were analyzed. RESULTS Significant discrepancies about the clinical and radiological outcomes, the rates of failure and complications as well as the variables influencing the treatment outcome occur in the published studies due to the heterogeneity of the data and the differences in the methods used. The overall short-, mid- or long-term success rate of the treatment ranges from 45% to 100% and it is commonly over 75%. The rate of osteonecrosis of the femoral head ranges from 1% to 30%. Age, gender, laterality, radiological or clinical severity of the initial hip pathology and parents' compliance are the commonly reported determinants of failure of the treatment. CONCLUSION The failure in treatment with the Pavlik harness is multifactorial, initial type of hip dysplasia being the most prominent followed by the treatment initiation age. This type of treatment cannot be considered as the best option in Graf IV hips (hip ultrasonography) or highly dislocated hips (plain radiography) and in infants older than three months of age, as the risk of failure and development of complications including osteonecrosis and femoral nerve palsy seem to increase in such circumstances. Large-scale, comparative studies including homogenous data are needed to answer the unsolved questions concerning indications.

Abstract
Developmental dysplasia of the hip (DDH) in infants under 6 months of age is typically treated by the Pavlik harness (PH). During successful PH treatment, a subluxed/dislocated hip is spontaneously reduced into the acetabulum, and DDH undergoes self-correction. PH treatment may fail due to avascular necrosis (AVN) of the femoral head. An improved understanding of mechanical factors accounting for the success/failure of PH treatment may arise from investigating articular cartilage contact pressure (CCP) within a hip during treatment. In this study, CCP in a cartilaginous infant hip was investigated through patient-specific finite element (FE) modeling. We simulated CCP of the hip equilibrated at 90 deg flexion at abduction angles of 40 deg, 60 deg, and 80 deg. We found that CCP was predominantly distributed on the anterior and posterior acetabulum, leaving the superior acetabulum (mainly superolateral) unloaded. From a mechanobiological perspective, hypothesizing that excessive pressure inhibits growth, our results qualitatively predicted increased obliquity and deepening of the acetabulum under such CCP distribution. This is the desired and observed therapeutic effect in successful PH treatment. The results also demonstrated increase in CCP as abduction increased. In particular, the simulation predicted large magnitude and concentrated CCP on the posterior wall of the acetabulum and the adjacent lateral femoral head at extreme abduction (80 deg). This CCP on lateral femoral head may reduce blood flow in femoral head vessels and contribute to AVN. Hence, this study provides insight into biomechanical factors potentially responsible for PH treatment success and complications.

Abstract
BACKGROUND Pavlik harness is the initial treatment for the infants with developmental dysplasia of the hip who have not yet begun walking. OBJECTIVES The present study evaluates the variables which affect the duration of PH treatment for patients successfully treated. STUDY DESIGN Cross-sectional study. METHODS Pavlik harness was employed for 140 hips of 87 patients with developmental dysplasia of the hip in our institution between 2010 and 2013. In all, 55 hips of 46 patients who were treated successfully with Pavlik harness were included in this study. According to Graf's sonographic classification, 23 hips were Type IIC, 26 were Type IID, and 6 were Type III. The studied variables were (1) alpha angle, (2) age at the start of treatment, (3) laterality, and (4) gender. The variables were compared with the duration of Pavlik harness treatment. RESULTS A highly significant inverse correlation was observed between Pavlik harness application time and alpha angle at the start of the treatment ( r = -0.050; p < 0.001). Bilateral involvement has statistically longer duration, when compared with unilateral involvement ( r = 0.28; p = 0.036). No statistically significant difference was present between duration of treatment and age at the start of Pavlik harness treatment ( r = -0.034; p = 0.804). There was no statistical significance between gender and duration of Pavlik harness ( r = 0.201; p > 0.05). CONCLUSION The duration of treatment was negatively correlated with the initial alpha angle. A change of 1 degree in alpha angle may alter the duration of treatment as 0.89 week calculated by the formula (Application time (Week) = 56.6 - 0.89 × alpha angle). Bilateral involvement may need longer Pavlik harness treatment. Clinical relevance Pavlik harnes generally is the first treatment method for the infants with DDH. This study suggest conclutions about how long time is the Pavlik harness should be kept on the infants? The main indicator is initial alfa angle which is negatively correlated with the duration of treatment.

Abstract
Performing surgical procedures often requires a surgeon to develop a skill to create 3-dimensional (3D) mental model on patient's anatomy. Question remains whether the touching on the 3D printed model can facilitate learning of patient anatomy than viewing the rendered virtual on-screen model. The printed and the virtual 3D model were developed from CT films taken from a 4-year-old girl, who had dysplasia of the hip in the left hip. Eleven subjects were called to report measures on six key anatomical features on the hips. The reporting time and the accuracy were compared between the two models, along with the gaze characteristics of subjects while inspecting the models. The variables were analysed using a 2 × 2 within subject ANOVA to examine the difference between viewing the models (on-screen vs. printed-out) and the side of the hip (right vs. left). Interacting with the printed 3D model required shorter times and yielded more accurate visual judgments than viewing the virtual models on most of the anatomical features. Subjects performed a fewer number of fixations but with a longer mean fixation duration when interacting the printed than inspecting the virtual on-screen 3D model. Results confirmed the value of the printed 3D model on improving the clinical judgement on patient anatomy. Confidence in collecting information from the physical world and the cross-model sensor integration may explain why participants performed better with the printed model compared to the virtual model.

Abstract
PURPOSE OF REVIEW Our understanding of the epidemiology, diagnosis, and management of developmental dysplasia of the hip (DDH) is evolving. This review focuses on the most up-to-date literature on DDH in patients from birth to six months of age. RECENT FINDINGS Well known risk factors for DDH include family history, female sex, and breech positioning. Recent evidence suggests higher birth weight is a risk, whereas prematurity may be protective. Screening includes physical examination of all infant hips and imaging when abnormal findings or risk factors are present. Treatment in the first six months consists of a harness, with 70-95% success. Failure risk factors include femoral nerve palsy, static bracing, irreducible hips, initiation after seven weeks of age, right hip dislocation, Graf-IV hips, and male sex. Rigid bracing may be trialed if reduction with a harness fails and closed reduction is indicated after failed bracing. If the hip is still irreducible, nonconcentric, or unstable, open reduction may be required following closed reduction. Evidence does not support delaying hip reduction until the ossific nucleus is present. SUMMARY DDH affects 1-7% of infants. All infants should be examined and selective screening with imaging should be performed for abnormal physical exams or risk factors. Early treatment is associated with optimal outcomes.

Abstract
In the UK, the Pavlik harness is generally the accepted treatment technique for the treatment of neonatal and infant pathological developmental dysplasia of the hip. In 2013, the success rate of the Pavlik harness became an outcome measure from the British Society of Children's Orthopaedic Surgery for appraisal and revalidation with the GMC for paediatric orthopaedic surgery. The standard set requires an 80% success rate, with less than 20% requiring surgery. This study evaluated the outcomes of Pavlik harness treatment in neonates/infants with 'pathological hips' diagnosed by ultrasound imaging in a district general hospital setting. In a 10-year prospective observational longitudinal cohort study, modified Graf type III and IV hips (excluding those presenting with irreducible hip dislocation) were classified as pathological and splinted. A total of 2826 neonates/infants underwent ultrasound assessment in the paediatric orthopaedic 'screening clinic'. Neonates and infants were referred as 'at-risk' or as clinically unstable by the Paediatric Department and by general practitioners. Thirty-one Graf type III and 95 Graf type IV hips were identified and treated with a Pavlik harness. One Graf type III (30/31=success rate 96.8%) and three clinically unstable Graf type IV hips progressed to irreducible hip dislocations (92/95=96.8%). The success rate of the Pavlik harness in Graf type III and IV dysplasia was 96.8%, with 3.2% requiring surgery because of progression of the condition, confirming acceptable results for this technique in a district general hospital setting.

Abstract
Developmental dysplasia of the hip (DDH) encompasses a wide spectrum of clinical severity, from mild developmental abnormalities to frank dislocation. Clinical hip instability occurs in 1% to 2% of full-term infants, and up to 15% have hip instability or hip immaturity detectable by imaging studies. Hip dysplasia is the most common cause of hip arthritis in women younger than 40 years and accounts for 5% to 10% of all total hip replacements in the United States. Newborn and periodic screening have been practiced for decades, because DDH is clinically silent during the first year of life, can be treated more effectively if detected early, and can have severe consequences if left untreated. However, screening programs and techniques are not uniform, and there is little evidence-based literature to support current practice, leading to controversy. Recent literature shows that many mild forms of DDH resolve without treatment, and there is a lack of agreement on ultrasonographic diagnostic criteria for DDH as a disease versus developmental variations. The American Academy of Pediatrics has not published any policy statements on DDH since its 2000 clinical practice guideline and accompanying technical report. Developments since then include a controversial US Preventive Services Task Force "inconclusive" determination regarding usefulness of DDH screening, several prospective studies supporting observation over treatment of minor ultrasonographic hip variations, and a recent evidence-based clinical practice guideline from the American Academy of Orthopaedic Surgeons on the detection and management of DDH in infants 0 to 6 months of age. The purpose of this clinical report was to provide literature-based updated direction for the clinician in screening and referral for DDH, with the primary goal of preventing and/or detecting a dislocated hip by 6 to 12 months of age in an otherwise healthy child, understanding that no screening program has eliminated late development or presentation of a dislocated hip and that the diagnosis and treatment of milder forms of hip dysplasia remain controversial.

Abstract
BACKGROUND Patients with developmental dysplasia of the hip (DDH) whose hips are dislocated but reducible (Ortolani positive) are more likely to experience Pavlik harness treatment failure than are patients with dysplastic and reduced but dislocatable (Barlow positive) hips. However, data regarding factors associated with failure are limited and conflicting. QUESTIONS/PURPOSES We asked: (1) What is the frequency of Pavlik harness treatment failure among Ortolani-positive hips, Barlow-positive hips, and dysplastic hips? (2) What are the factors predictive of failure of Pavlik harness treatment for Ortolani-positive hips? METHODS In this retrospective study we identified 150 patients who underwent the Pavlik harness method for treatment of DDH between August 2011 and July 2015. Six patients initially treated at an outside facility, four patients with associated conditions, and three who pursued treatment elsewhere were excluded. A total of 137 patients (215 hips) with a median age at the time of Pavlik placement of 30 days (range, 4-155 days) were included. Of the 215 hips, 78 (36.3%) were Ortolani positive, 60 (27.9%) were Barlow positive, and 77 (35.8%) were stable, with the diagnosis of dysplasia made on ultrasound. All patients were treated with the Pavlik harness method. The primary outcome was failure of the Pavlik harness to achieve and maintain concentric hip reduction assessed by examination and ultrasound. All patients were followed after completion of Pavlik treatment for a minimum of 2 months (mean, 3 months; range, 2-4 months). In addition, 90% (122 of 137) of the patients were followed for a minimum of 6 months. Patient-specific data including family history, breech versus cephalic presentation at birth, age, sex, laterality, and hip abduction were recorded. Ultrasound data at the time of diagnosis included Graf classification, alpha angle, and percentage of femoral head coverage. RESULTS The Pavlik harness method failed in 27% (21 of 78) of hips that were Ortolani positive, 8% (six of 77) with dysplasia, and 5% (three of 60) that were Barlow positive. After controlling for potential confounding variables, such as range of hip abduction, male sex (adjusted odds ratio [OR], 6.9; 95% CI, 2.0-24.2; p = 0.002) and Graf Type IV ultrasound classification (dislocated hip with alpha angle less than 43° and labrum displaced downward) (OR, 4.4; 95% CI, 1.3-15.4; p = 0.019) were identified as independent predictors of failure of Pavlik treatment among Ortolani-positive hips. CONCLUSIONS Ultrasound imaging of the hip should be part of the initial assessment for Ortolani-positive hips, as the ultrasound classification was found to have prognostic implications. Parents of male infants with Graf Type IV hips should be counseled regarding the higher risk of Pavlik failure. Future well-designed prospective controlled studies are necessary to establish whether alternative strategies to the Pavlik harness might improve the early outcomes of DDH in males with Graf Type IV hips.

Abstract
BACKGROUND Treatment of developmental dysplasia of the hip (DDH) using the Pavlik harness has been a widely used method in patients between 0 and 6 months of age for many years. However, the factors influencing the success rate of this treatment modality have still not exactly been determined as a result of the limited number of clinical studies with higher level of evidence. QUESTIONS/PURPOSES We, therefore, asked whether (1) patient-related variables such as age, gender, and laterality; coexisting risk factors including family history, breech presentation, intrauterine packing, first-born girl, oligohydroamnios, and swaddling; and (2) the severity of hip dysplasia, defined by ultrasonography, are associated with differences in the success rate of Pavlik harness treatment in infants with DDH. METHODS Between 2012 and 2014, we treated 153 children (≤ 6 months of age) with DDH using the Pavlik harness. Hip dysplasia apart from coexisting neuromuscular disorders, congenital abnormalities, or syndromes was our inclusion criteria. Of patients thus treated, 130 (85%) were available for the evaluation of patient- and hip-related variables against the success of Pavlik harness treatment. Mean age of these patients on day of diagnosis and initiation of treatment was 108 days. The diagnostic and followup examinations of the hips were made by ultrasonography using Graf's method. Pavlik harness treatment was initiated in Graf Type IIa- and worse hips and treatment was considered "successful" when a Graf Type I hip was achieved. Pavlik harness treatment was successful in 92 (71%) patients (130 of 181 hips [72%]). RESULTS Age was the only patient-related variable influencing the success rate of the treatment; the mean age of children in whom Pavlik harness treatment succeeded (97 ± 38 days; 95% confidence interval [CI], 90-112) was lower than the age of those who failed (135 ± 37 days; 95% CI, 123-147; p < 0.001). The highest success rate was obtained in children younger than age 3 months (37 of 40 [93%]) and the lowest one older than age 5 months (nine of 24 [37%]) (p < 0.001). The threshold age value related to an increased risk of failure was found to be 4 months and older, which had a sensitivity of 66% and a specificity of 77% (p < 0.001). A higher initial α angle was observed in the hips in which the treatment succeeded (53° ± 6°; 95% CI, 51°-53°) than in those that failed (47° ± 7°; 95% CI, 45°-50°; p < 0.001). The threshold α angle value related to an increased risk of treatment failure was 46° and less, which had a sensitivity of 47% and a specificity of 86% (p < 0.001). Dislocated hips (Graf Type III and IV hips) had the lowest rate of treatment success (five of 19 [26%] and two of four [50%], respectively), whereas Graf Type IIa- hips had the highest (27 of 29 [93%]) (p < 0.001). CONCLUSIONS We conclude that Pavlik harness treatment is less effective in children at and over the age of 4 months at the time the harness is first applied as well as in hips with complete dislocations and hips with severely deficient acetabular bony roofs. In such older patients and worse hip types, the use of initial Pavlik harness treatment needs to be revisited. Future studies, comparing the outcomes of the Pavlik harness treatment and other types of interventions in such patients and hip types, are needed. LEVEL OF EVIDENCE Level III, therapeutic study.

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.

Abstract
BACKGROUND It is believed that bilateral developmental dysplasia of the hip (DDH) has poorer outcomes with higher rates of avascular necrosis (AVN) and reintervention, compared with unilateral DDH. However, there is limited evidence in the literature, with few studies looking specifically at bilateral cases. METHODS A retrospective review of 36 patients (72 hips) with >4 years of follow-up. Patient population included surgically treated DDH including late presentations and failures of conservative treatment. The dislocated hips underwent either simultaneous closed or 1 open and 1 closed, or sequential open reduction. AVN and secondary procedures were used as endpoints for analysis as well as clinical and radiologic outcomes. RESULTS At the last follow-up, 33% of hips had radiologic signs of AVN. Those hips that had no ossific nucleus (ON) at the time of surgery had an odds ratio of developing AVN of 3.05 and a statistically significant association between the 2 variables, whereas open/closed or simultaneous/sequential reduction did not increase the risk for AVN. In addition, 45.8% of those hips required further surgery. The estimated odds ratio of needing additional surgery after simultaneous reduction was 4.04. Clinically, 79.2% of the hips were graded as McKay I, whereas radiologically only 38.8% were Severin I. CONCLUSIONS The AVN rate in bilateral DDH treated surgically is greater than the rate noted in unilateral cases from the same institution undergoing identical protocols. There was no difference in AVN rates between simultaneous and sequential or between the first and second hip to be sequentially reduced. Presence of ON decreases the risk for AVN, suggesting that in bilateral cases, awaiting the appearance of the ON is an important tool to reduce the incidence of AVN. LEVEL OF EVIDENCE IV.

Abstract
INTRODUCTION Orthopaedic treatment of developmental dysplasia of the hip (DDH) has a high success rate in cases that are diagnosed early. However, the outcomes of these patients are not really known when they are subsequently diagnosed with some type of cerebral impairment. MATERIALS AND METHODS A retrospective observational study was conducted on cases of DDH with a poor outcome after orthopaedic treatment, being unknown if they had any type of psychomotor disorder. The patients were clinically and radiologically assessed, and afterwards received neurological valuation by the Child Neurology Unit. RESULTS Of the 325 cases of DDH diagnosed in 293 patients, 10 patients (3%) with 16 hips with DDH were diagnosed of any cerebral impairment. All them were initially treated orthopedically. Clinical and radiologically evolution was succesful only in 4 cases (25%) being necessary any surgical procedure in the remaining 12 cases. After surgical treatment we got an improvement in the Acetabular Index (p=0.005) and Reimers Extrusion Index (p=0.042). Neck-shaft angle and Wiberg CE angle also improved but this difference was not statically significant. Cerebral impairment was diagnosed at 2,5 years of age and the begining of walking was delayed at 2.4 years of age. CONCLUSIONS Cerebral impairment can lead to an unfavourable outcome in the treatment of DDH, with the relative risk of a poor outcome being 7.2 times higher in these patients. An unfavourable outcome with conventional treatment of DDH must make us suspect the presence of some type of neurological disorder, particularly if there is a delay in walking.

Abstract
BACKGROUND Predictors of failure of the Pavlik harness in reducing and stabilizing an Ortolani-positive hip remain 'unclear'. The purpose of this study is to investigate the success of the Pavlik harness when treating Ortolani-positive hips, to look for predictors of failure of the harness and to analyze the arthrographic findings among these failures. MATERIALS AND METHODS The medical records of 39 consecutive patients with an Ortolani-positive hip treated initially with a Pavlik harness were reviewed. Data regarding birth order, problems during pregnancy, presentation at birth, delivery, family history of DDH, gender, side involved, bilaterality, onset of treatment, problems related to use of the harness, and time until the harness reduced and stabilized the hip or was abandoned because of a failure were recorded. The presence of plagiocephaly, torticollis or foot deformity was also noted. We looked for predictors of failure among these aspects and report the arthrographic findings of the failures. RESULTS The mean age when the harness was started was 16.7 days. The mean time until success or failure of the harness in reducing and stabilize the hip was 18.5 days. There were 8 (20.5 %) failures. Multigravida (p = 0.026) and foot deformity (p = 0.023) were associated with failure of the harness. On the other hand, problems during pregnancy (p = 1), presentation at birth (p = 0.078), c-section (p = 0.394), family history of DDH (p = 1), gender (0.313), torticollis (p = 1), bilaterality (p = 1) and onset of treatment (p = 0.485) were not associated. Arthrographic abnormalities were found in all failures. CONCLUSION The Pavlik harness failed to reduce and stabilize the hip in 20.5 % of the newborns with an Ortolani-positive hip. Multigravida and foot deformity were statistically associated with failure of the harness. An anatomical obstacle for reduction was found in all hips with a harness failure. A more teratological than mechanical hip dislocation could be the reason for failure of the Pavlik harness. LEVEL OF EVIDENCE IV, Retrospective case series.

Abstract
BACKGROUND Existing radiographic classification schemes (eg, Tönnis criteria) for DDH quantify the severity of disease based on the position of the ossific nucleus relative to Hilgenreiner's and Perkin's lines. By definition, this method requires the presence of an ossification centre, which can be delayed in appearance and eccentric in location within the femoral head. A new radiographic classification system has been developed by the International Hip Dysplasia Institute (IHDI), which uses the mid-point of the proximal femoral metaphysis as a reference landmark, and can therefore be applied to children of all ages. The purpose of this study was to compare the reliability of this new method with that of Tönnis, as the first step in establishing its validity and clinical utility. METHODS Twenty standardized anteroposterior pelvic radiographs of children with untreated DDH were selected purposefully to capture the spectrum of age (range, 3 to 32 mo) at presentation and disease severity. Each of the hips was classified separately by the IHDI and Tönnis methods by 6 experienced pediatric orthopaedists from the United States, Canada, Mexico, United Kingdom, and by 2 orthopaedic senior residents. The inter-rater reliability was tested using the Intra Class Correlation coefficient (ICC) to measure concordance between raters. RESULTS All 40 hips were classifiable by the IHDI method by all raters. Ten of the 40 hips could not be classified by the Tönnis method because of the absence of the ossific nucleus on one or both sides. The ICC (95% confidence interval) for the IHDI method for all raters was 0.90 (0.83-0.95) and 0.95 (0.91-0.98) for the right and left hips, respectively. The corresponding ICCs for the Tönnis method were 0.63 (0.46-0.80) and 0.60 (0.43-0.78), respectively. There was no significant difference between the ICCs of the 6 experts and 2 trainees. CONCLUSIONS The IHDI method of classification has excellent inter-rater reliability, both among experts and novices, and is more widely applicable than the Tönnis method as it can be applied even when the ossification centre is absent.

Abstract
BACKGROUND Avascular necrosis (AVN) of the femoral head is an irreversible complication seen in the treatment of developmental dysplasia of hip (DDH) with the Pavlik harness. Its incidence is reported to be low after successful reduction of the hip but high if the hip is not concentrically relocated. We aim to investigate its incidence after failed Pavlik harness treatment. METHODS We prospectively followed up a group of children who failed Pavlik harness treatment for DDH treated at our institution by the senior author between 1988 and 2001 and compared their rates of AVN with a group of children who presented late and hence were treated surgically. AVN was graded as described by Kalamchi and MacEwen and only grade 2 to 4 AVN was considered significant and included in the analysis. RESULTS Thirty-seven hips were included in the failed Pavlik group (group 1) and 86 hips in the no Pavlik group (group 2). Ten hips in group 1 developed AVN (27%), whereas only 7 hips in group 2 (8%) developed AVN; the odds of developing AVN after failed Pavlik treatment was 4.7 (95% confidence interval, 1.3-14.1) (P=0.009) with a relative risk of 3.32 (range, 1.37 to 8.05). CONCLUSIONS There was no statistically significant association observed with duration of splintage and severity of AVN (Spearman's correlation, -0.46; P=0.18). However, there was a positive correlation noted with age at presentation and severity of AVN. Therefore, we advise close monitoring of hips in the Pavlik harness and discontinue its use if the hips are not reduced within 3 weeks. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Developmental dysplasia of the hip (DDH) is rarely encountered in the native sub-Saharan African population. We present a retrospective review of the incidence of symptomatic DDH in Malawi and a systematic review of the role of back-carrying as a potential influence of prevalence in this population group. METHODS We retrospectively reviewed the diagnosis and management of all infants seen at the Beit CURE International Hospital, Malawi and its mobile clinics, from November 2002 to September 2012. In addition, methodical review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist and algorithm was performed. RESULTS A total of 40,683 children aged less than 16 years were managed at our institute over a 10-year period, of which 9842 children underwent surgery. No infant presented with, or underwent surgical intervention, for symptomatic DDH. CONCLUSIONS The majority of mothers in Malawi back-carry their infants during the first 2 to 24 months of life, in a position that is similar to that of the Pavlik harness. We believe this to be the prime reason for the low incidence of DDH in the country. In addition, there is established evidence indicating that swaddling, the opposite position to back-carrying, causes an increase in the incidence of DDH. There is a need for the establishment of a large clinical trial into back-carrying and prevention of DDH in non-African population groups. LEVEL OF EVIDENCE Level II.

Abstract
Developmental dysplasia of the hip (DDH) encompasses a spectrum of physical and imaging findings. The child's hip will not develop normally if it remains unstable and anatomically abnormal by walking age. Therefore, careful physical examination of all infants to diagnosis and treat significant DDH is critical to provide the best possible functional outcome. Regardless of the practice setting, all health professionals who care for newborns and infants should be trained to evaluate the infant hip for instability and to provide appropriate and early conservative treatment or referral.

Abstract
The diagnosis and treatment of developmental dysplasia of the hip in the infant are uniform, with consensus that diagnostic ultrasound and Pavlik harness management are standard procedures. Sequential procedures for failed early treatment, residual dysplasia and late diagnosis are dependent on the age and the severity of the dysplasia. This paper reviews the treatment of developmental dysplasia of the hip from birth to subsequent follow-up procedures, with particular reference to some of the senior authors' research and the Southampton approach to the management of hip dysplasia.

Abstract
Developmental dysplasia of the hip (DDH) is common because it is present in 1 of 100 newborns. Failure to diagnose DDH and treat in infancy can result in significant long-term disability. Early diagnosis can be accomplished through a quick but careful physical examination of all newborns. Further selective screening by ultrasound is indicated for those children with risk factors for DDH, which include family history, breech presentation, and unstable hip examination at the initial newborn examination. Continued examination of the hip at all routine well-child checkups is mandatory through the first year of life because late presenting DDH may occur. Treatment with a Pavlik harness is not typically instituted in the neonate because many unstable hips stabilize without intervention, but it is indicated in children older than 2 weeks with hip instability. Ultrasound screening for infants with risk factors for DDH is recommended at age 6 weeks. Pavlik harness treatment for children with unstable hips or significant dysplasia on ultrasound is continued until the hips stabilize and show concentric reduction on imaging. With time, diagnosis and treatment evolve to accommodate the growing child. Infants who fail to respond to nonoperative management may require more extensive interventions. At any time when treatment is initiated, a DDH specialist should be involved in the patient's care. If DDH is recognized early, treatment is less invasive, and long-term effects are minimized.

Abstract
We present a systematic review of the use of the Pavlik method in developmental dysplasia of the hip. Our aims were to evaluate treatment protocols, reported results and factors associated with successful outcomes. We found 218 relevant citations, of which 62 fulfilled our inclusion criteria. Our results have shown satisfactory clinical and radiological outcomes with the use of the harness at long-term follow-up. However, failures of harness use have been reported along with episodes of avascular necrosis. Ultrasound plays a key role in the early detection of such cases. Alternative methods of splintage have been described but larger comparative studies are required to change current practice.

Abstract
BACKGROUND In children over 6 months of age with developmental dysplasia of the hip (DDH), achieving a concentrically reduced hip while avoiding avascular necrosis (AVN) is challenging. The utility of gradual reduction (GR) using traction has insufficient evidence. We therefore report the long-term outcome of GR using overhead traction (OHT). METHODS We retrospectively reviewed 67 patients with DDH (75 hips) treated with GR using OHT over 6 months of age. The age at reduction ranged from 7 months to 4 years. All patients were followed up until skeletal maturity with a mean duration of 15.6 years. Pelvic radiographs were used to assess AVN, acetabular development, and the Severin classification. We determined the factors affecting the outcome at skeletal maturity. RESULTS Seventy-two hips (96%) were successfully reduced, 2 required subsequent closed reduction and 1 underwent open reduction. AVN occurred in 2 hips (2.7%). Among 48 hips (64%) with residual acetabular dysplasia, 31 were treated with Salter innominate osteotomy (SIO) between 5 and 6 years of age. Finally, 62 hips (82.7%) showed satisfactory outcome (56 in Severin class I and 6 in class II), whereas 13 showed unsatisfactory outcome (class III). Although we found no significant factors affecting the outcome, most of the hips treated with SIO were included in the satisfactory group. CONCLUSIONS GR using OHT could effectively minimize the risk of developing AVN in patients with DDH over 6 months of age at presentation. SIO at preschool age may play a beneficial role in the long-term outcome of GR using OHT.

Abstract
Developmental dysplasia of the hip (DDH) denotes a wide spectrum of conditions ranging from subtle acetabular dysplasia to irreducible hip dislocations. Clinical diagnostic tests complement ultrasound imaging in allowing diagnosis, classification and monitoring of this condition. Classification systems relate to the alpha and beta angles in addition to the dynamic coverage index (DCI). Screening programmes for DDH show considerable geographic variation; certain risk factors have been identified which necessitate ultrasound assessment of the newborn. The treatment of DDH has undergone significant evolution, but the current gold standard is still the Pavlik harness. Duration of Pavlik harness treatment has been reported to range from 3 to 9.3 mo. The beta angle, DCI and the superior/lateral femoral head displacement can be assessed via ultrasound to estimate the likelihood of success. Success rates of between 7% and 99% have been reported when using the harness to treat DDH. Avascular necrosis remains the most devastating complication of harness usage with a reported rate of between 0% and 28%. Alternative non-surgical treatment methods used for DDH include devices proposed by LeDamany, Frejka, Lorenz and Ortolani. The Rosen splint and Wagner stocking have also been used for DDH treatment. Surgical treatment for DDH comprises open reduction alongside a combination of femoral or pelvic osteotomies. Femoral osteotomies are carried out in cases of excessive anteversion or valgus deformity of the femoral neck. The two principal pelvic osteotomies most commonly performed are the Salter osteotomy and Pemberton acetabuloplasty. Serious surgical complications include epiphyseal damage, sciatic nerve damage and femoral neck fracture.
