Abstract
Acetabular underdevelopment (acetabular dysplasia) is a common finding in children with hip dislocation, and residual acetabular dysplasia can remain after hip reduction. Residual dysplasia leads to unsatisfactory long-term outcomes and osteoarthritis. Dynamics of acetabular dysplasia [measured as Acetabular Index (AI)] in a pediatric cohort that underwent open (OR) or closed reduction are reported. Retrospective data from six tertiary pediatric orthopedic centers were gathered. Hips were classified as having 'Critical', 'Monitoring', or 'Normal' acetabular dysplasia based on age-adjusted normative AI measurements. From 193 hips, 108 (56%) underwent open reduction. Children younger than 24 months had a strong AI decline but children > 24 months did not. Among 78 hips with critical dysplasia at time of OR, 36 (46.2%) remained critical and 19 (24.4%) underwent an acetabular osteotomy (AO) during follow-up. CR hips had a similar AI decline in patients younger and older than 12 months. Among 51 hips with critical dysplasia at the time of CR, 13 (25.5%) remained critical and 21 (41.2%) underwent AO during follow-up. Acetabular dysplasia improves with AI decreasing in children who undergo OR and CR under the age of 2 years with slower acetabular remodeling afterwards. Around 2/3 of patients with AI in the critical range at CR or OR either underwent AO or had significant acetabular dysplasia at final follow-up. Our data supports considering simultaneous AO at the time of OR for hips with AI in the critical range or children who undergo hip open reduction after 24 months of age. Level of Evidence: Level III.

A modified angled plate for fixation of proximal femoral varus osteotomy in neuromuscular hip dislocation: Mechanical and clinical study. Orthop Traumatol Surg Res 2024; 110:103674. [PMID: 37666326 DOI: 10.1016/j.otsr.2023.103674] [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: 01/13/2023] [Revised: 08/25/2023] [Accepted: 08/29/2023] [Indexed: 09/06/2023]
Abstract
INTRODUCTION Proximal femoral osteotomy is an important step in the management of paralytic hip dislocation. Fixation by the angled plate is demanding and carries the risk of many complications. In this study, we made certain modifications for the angled plate. Does this plate provide a stable fixation for proximal femoral varus osteotomy? The main objective of this study was to assess the results of the modified plate in fixation of proximal femoral varus osteotomy in patients with neuromuscular hip dislocation. HYPOTHESIS This new system would offer significant advantages over the existing systems in terms of easy application and stable fixation. MATERIAL AND METHODS Twenty patients with paralytic hip dislocation were included in this study. The ages ranged from 5 to 15 years with a mean of 8.88±2.92 years. There were 12 boys and 8 girls. Seventeen patients had cerebral palsy and 3 had meningocele disease. Preoperative radiographs were done, and the migration percentage (MP), acetabular index (AI), and neck-shaft angle (NSA) were measured. All patients were treated with open reduction, pelvic osteotomy, and proximal femoral varus osteotomy. The femoral osteotomy was fixed by the modified angled plate in all cases. RESULTS The osteotomy sites united in all patients and the mean time of union was 2.9±0.65 months. The acetabular index, migration percentage, and neck-shaft angle were reduced postoperatively. This reduction was statistically significant. The hips remained stable throughout the period of follow-up in all patients. No cases were complicated by non-union or implant failure. CONCLUSION The modified angled plate (canulated interlocking blade Plate 90°) is a good method for the fixation of proximal femoral varus osteotomy in the management of neuromuscular hip dislocation. It provides a stable fixation. LEVEL OF EVIDENCE IV; case series.

Abstract
Background Traction is used at our hospital before open reduction in infants with developmental dysplasia of the hip. Theoretically, it reduces soft-tissue tension, allowing an easier surgical reduction and therefore lower surgical complications. Owing to extended hospital stays, potential complications, and lack of evidence, the use of traction has decreased. This study aims to quantify whether traction is safe and whether it has any demonstrable effect. Methods The perioperative course of 80 patients undergoing preoperative traction and hip open reduction were reviewed. The height of hip dislocation was classified using the International Hip Dysplasia Institute classification system on both radiographs taken before and after traction. Any complications related to traction were recorded, along with the requirement for femoral shortening osteotomies, incidence of re-dislocation, and longer-term rate of avascular necrosis. Results Traction lowered the resting position of the majority of hips, with the median International Hip Dysplasia Institute grade before traction improving from 4 to 3, a statistically significant improvement (p < 0.00001). There were no neurovascular complications. Two babies were complicated with broken skin sores; however, surgery still progressed uneventfully. Zero hips in the cohort required femoral shortening osteotomies to achieve a tension-free reduction, and the re-dislocation rate was 0%. However, 96% of hips were Severin 1 or 2 at 6-year follow-up. Conclusion Notably, 1 week of preoperative traction significantly improves the resting position of the hip in high dislocations. It is safe when used in infants weighing <12 kg, and subsequent surgical outcomes are excellent, thus supporting its use ahead of developmental dysplasia of the hip open reduction surgery. Level of evidence Level IV.

Abstract
INTRODUCTION The current published evidence for the treatment of developmental dysplasia of the hip (DDH) with failed closed reduction (CR) following failed Pavlik harness (PH) treatment is still limited. This study aimed to determine whether an one-stage open reduction (OR) would lead to a similar outcome to a two-stage OR in these patients. Meanwhile, the occurrence of femoral head avascular necrosis (AVN) and further surgery (pelvic osteotomy, PO) within the follow-up period was investigated. MATERIALS AND METHODS A consecutive series of DDH patients who failed CR following failed PH treatment and received OR finally between January 2008 and December 2020 were studied. The patients were divided into two groups. One group of which received OR immediately after failed CR (one-stage OR group, Group A), and the other received a delayed OR (two-stage OR group, Group B). The McKay's criteria, acetabular index (AI) and the degree of dislocation of the hips were evaluated for the final outcomes. RESULTS At the last follow-up, 54 (84.4%) of the 64 hips in Group A and 26 (83.9%) of 31 hips in Group B were in excellent or good condition. Comparison between the two groups revealed that there were no differences in terms of McKay grading (P = 0.950), AI (P = 0.783), incidence of AVN (P = 0.745), and also incidence of PO (P = 1.000). However, a significant lower mean AI was found in Group A, when the OR was performed in Group B (31.06 ± 4.45° vs. 33.87 ± 4.12°, P = 0.004). CONCLUSION Both of the one- and two-stage OR may acheive favorable outcomes. Moreover, one-stage OR is of without the general anesthesia risk associated with two-stage OR. We therefore advocate that an OR should be performed in appropriate DDH patients during the same session once a failed CR is detected.

Abstract
OBJECTIVES Despite the success rate of the Pavlik method in the treatment of developmental dislocation of the hip, there is a subset of hips that do not reduce with harness use. The purpose of this study was to determine the outcomes after closed reduction (CR), open reduction (OR) and combined open reduction and pelvic osteotomy (OR+PO) in patients with infantile hip dislocations who initially failed the Pavlik method. METHODS This was a retrospective cohort study of patients with infantile hip dislocations who failed the Pavlik method and subsequently underwent a secondary procedure for persistent hip dislocation. The primary outcome measure was the Severin classification of the involved hip 3 years after the secondary procedure. Other outcomes assessed included rates of redislocation, residual acetabular dysplasia and proximal femoral growth disturbance. RESULTS Twenty-three patients were included; seven subsequently underwent CR, three underwent isolated OR and 13 proceeded directly to OR+PO. The overall successful outcome rate at final follow-up (as determined by radiographic Severin class I or II) was 11/23 (48%). However, patients undergoing OR+PO had significantly higher rates of successful outcomes (77%) compared with CR (15%) and OR (0%), P < 0.05. The rate of residual acetabular dysplasia and proximal femoral growth disturbance was significantly lower in patients treated with OR+PO compared with CR and isolated OR, P < 0.05. CONCLUSION Patients with dislocated hips who failed Pavlik harness treatment had better radiographic outcomes 3 years after OR+PO in comparison to patients undergoing CR or isolated OR.

Abstract
BACKGROUND The primary objective was to report our early results after a one-stage procedure [open reduction (OR), Dega pelvic osteotomy (DPO), and femoral osteotomy (FO) when needed] for surgical management of a cohort of patients with developmental dysplasia of the hip (DDH). The secondary objective was to compare the functional, radiological, and complications among patients younger and older than 30 months. MATERIALS AND METHODS This prospective cohort study included 71 hips with DDH in 61 patients with a mean age of 34.3 ± 19.5 months. All patients underwent one-stage surgical procedures, including OR + DPO and FO, if needed. Functional and radiographic assessment at the last follow-up was conducted using the modified Severin grading system and the Severin classification system, respectively, in addition to assessing the acetabular index (AI), osteotomies healing, and presence of complications. We divided patients into two groups, younger than 30 months (group I) and older than 30 months (group II). RESULTS We included 35 hips in group I and 36 in group II. All hips received OR + DPO, while 25 (69.4%) hips in group II had FO. The operative time was significantly longer in group II (103.19 ± 20.74 versus 72.43 ± 11.59 min, p < 0.001). After a mean follow up of 21.3 ± 2.3 months, the functional outcomes were satisfactory in 62 (87.3%) hips (94.3% in group I and 80.6% in group II, p = 0.35). There was a significant improvement in the AI in all patients compared with preoperative values (27.2° ± 2.9 versus 37° ± 4.2, p < 0.05). Furthermore, 63 (88.7%) hips had satisfactory radiographic outcomes (94.3% in group I and 83.3% in group II, p = 0.26), and all osteotomies showed radiographic healing. The overall complications incidence was significantly lower in group I compared with group II (5.7% versus 30.6%, p < 0.05), and avascular necrosis occurred in 4 (5.6%) hips, all in group II (p = 0.06). CONCLUSION One-stage procedure entailing open reduction, Dega pelvic osteotomy, and femoral osteotomy when needed for managing DDH in patients younger than eight years old revealed acceptable clinical and radiological outcomes. However, there was a higher need for a concomitant femoral osteotomy in patients older than 2.5 years, and complications were more frequent. LEVEL OF EVIDENCE III

Abstract
BACKGROUND Although there are several predominantly single-center case series in the literature, relatively little prospectively collected data exist regarding the outcomes of open hip reduction (OR) for infantile developmental dysplasia of the hip (DDH). The purpose of this prospective, multi-center study was to determine the outcomes after OR in a diverse patient population. METHODS The prospectively collected database of an international multicenter study group was queried for all patients treated with OR for DDH. Minimum follow-up was 1 year. Proximal femoral growth disturbance (PFGD) was defined by consensus review using Salter's criteria. Persistent acetabular dysplasia was defined as an acetabular index >90th percentile for age. Statistical analyses were performed to compare preoperative and operative characteristics that predicted re-dislocation, PFGD, and residual acetabular dysplasia. RESULTS A cohort of 232 hips (195 patients) was identified; median age at OR was 19 months (interquartile range 13 to 28) and median follow-up length was 21 months (interquartile range 16 to 32). Re-dislocation occurred in 7% of hips (n=16/228). The majority (81%; n=13/16) occurred in the first year after initial OR. Excluding patients with repeat dislocation, 94.5% of hips were IHDI 1 at most recent follow-up. On the basis of strict radiographic review, some degree of PFGD was present in 44% of hips (n=101/230) at most recent follow-up. Seventy-eight hips (55%) demonstrated residual dysplasia compared with established normative data. Hips that had a pelvic osteotomy at index surgery had about half the rate of residual dysplasia (39%; n=32/82) versus those without a pelvic osteotomy with at least 2 years follow-up (78%; n=46/59). CONCLUSIONS In the largest prospective, multicenter study to date, OR for infantile DDH was associated with a 7% risk of re-dislocation, 44% risk of PFGD, and 55% risk of residual acetabular dysplasia at short term follow-up. The incidence of these adverse outcomes is higher than previous reports. Patients treated with concomitant pelvic osteotomy had lower rates of residual dysplasia. These prospectively collected, multicenter data provide better generalizable information to improve family education and appropriately set expectations.

Abstract
BACKGROUND This investigation aimed to determine the degree of correlation among 3 functional scales for evaluating the hip in pediatric patients and determine the correlation between measures of global function and outcome. METHODS We performed a prospective study of 173 consecutive patients (M age = 13 ± 3 y) being followed for developmental dysplasia of the hip (n = 122, 71%), slipped capital femoral epiphysis (n = 31, 18%), or Legg-Calve-Perthes disease (n = 20, 12%). We evaluated patients clinically, and we compiled scores for the Iowa Hip Score (IHS), Harris Hip Score (HHS), and Children's Hospital Oakland Hip Evaluation Scale (CHOHES). Patients concomitantly completed the Pediatric Outcomes Data Collection Instrument (PODCI) at the same clinic visit. We assessed Global Functioning Scale the and the Sports and Physical Functioning Core Scale of the PODCI. We determined the degree of correlation between the functional hip scales and between each scale and the PODCI scales using Spearman rank correlation coefficients. RESULTS The correlations between the IHS, HHS, and CHOHES scores were robust (IHS and HHS ρ = 0.991; IHS and CHOHES ρ = 0.933; HHS and CHOHES ρ = 0.938; all P < 0.001). The correlation between the Global Functioning Scale of the PODCI and the 3 hip scores was ρ = 0.343 for the IHS, ρ = 0.341 for the HHS, and ρ = 0.352 for the CHOHES (all P < 0.001). The correlation between the sports and physical functioning core scale of the PODCI and the 3 hip scores was ρ = 0.324 for the IHS, ρ = 0.329 for the HHS, and ρ = 0.346 for the CHOHES (all P < 0.001). CONCLUSIONS In a pediatric population with diverse hip pathology, there was a very strong correlation between scores on the IHS, HHS, and CHOHES. However, none of these 3 most commonly used hip scores correlated strongly with the global functioning scale or sports and physical functioning core scale of the PODCI. The most frequently used scores to determine the outcome of pediatric patients with hip pathology correlate strongly with each other but do not necessarily relate to global functional results.

Abstract
Background Due to various policy and health infrastructure issues, it is not uncommon to present developmental dysplasia of hip(DDH) at walking-age in India. The purpose of this study was retrospective analysis of operated cases of walking-age DDH with "inferior over-reduction". Methods "Inferior over-reduction" was defined as break in the Shenton's arc inferiorly in an operated hip which otherwise appears reduced. After Ethical Committee approval, we searched children operated for walking-age DDH. Children suggestive of syndromic association were excluded. We collected demographic data, follow-up, procedures performed, inferior over-reduction and complications. The IHDI grade, Acetabular Index(AI), Smith's ratio for superior (h/b) & lateral displacement(c/b) of femur, and clinical outcome (Modified McKay criteria) were evaluated. The outcomes of cases with inferior over-reduction(Group A) were compared with those without(Group B). Results 42 patients with average follow-up of 23 months were enrolled. 21 hips belonged to Group A. By 6 months follow up, all these cases recovered. On comparison of Smith's ratio, group A had significantly higher c/b for the operated hip at 3-month follow-up(p < 0.05). Patients undergoing acetabuloplasty had significantly lower c/b versus all other groups(p < 0.05). Correlation between h/b or c/b with age did not show any significant finding. 15 cases in group A and 14 cases in group B had excellent outcome as per modified McKay's criteria. None of the patients had inferior over-reduction, inferior or obturator dislocation at final follow-up. Three patients with group B had re-dislocation with poor outcome. we recorded 3 hips with AVN (7%). Conclusions This study highlights that after OR of walking-age DDH, the inferior over-reduction may be noted in as much as 50% of the cases. However, this is transient, and all cases recover by the 6 months follow up. There is no significant difference between group A & B in functional outcome, AVN rate. Long-term studies are required to see outcome differences between two groups.

Abstract
BACKGROUND Children undergoing DDH correction surgery may experience gait abnormalities following soft tissue releases and bony procedures. The purpose of this study was to compare the residual gait changes, radiological outcomes, and functional outcomes in children who underwent DDH surgery with those in healthy controls. METHODS Inertial motion sensors were used to record the gait of 14 children with DDH and 14 healthy children. Pelvic X-ray was performed to determine the Severin classification and the presence of femoral head osteonecrosis (Bucholz-Odgen classification). For functional evaluation, the Children's Hospital Oakland Hip Evaluation Scale (CHOHES) was used. RESULTS There was no difference in spatial parameters between the two groups. In terms of temporal parameters, the DDH-affected limbs had a shorter stance phase (p < 0.001) and a longer swing phase (p < 0.001) than the control group. The kinematic study showed that the affected limb group had smaller hip adduction angle (p = 0.002) and increased internal rotation (p = 0.006) with reduced upward pelvic tilt (p = 0.020). Osteonecrosis was graded II, III, and IV in five, three, and one patients, respectively. Five patients had no AVN changes. The Severin classification was grade I, II, and III for six, three, and five patients, respectively. Most patients had good functional outcomes on the CHOHES, with a mean total score of 96.64 ± 5.719. Multivariate regression analysis revealed that weight, height, and femoral osteotomy were independent predictors for gait, radiological and functional outcome. CONCLUSION Despite good functional scores overall, some children had poor radiological outcomes and gait abnormalities. Our results identified the risk factors for poor outcomes, and we recommend specified rehabilitative strategies for long-term management.

Abstract
BACKGROUND A fundamental tenent of treating developmental dysplasia of the hip is to identify patients with dislocated hips early so as to avoid the long-term sequelae of late diagnosis. The aim of this study was to develop a readily useable triage tool for patients with suspected hip dislocation, based on the clinical history and examination findings of the referring practitioner. METHODS All primary care referrals (n=934) over a 3-year period for suspected developmental dysplasia of the hip to a tertiary pediatric center were evaluated. Defined parameters with respect to history and clinical examination were evaluated. Multivariable logistic regression was used to establish predictors of hip dislocation, and from this a predictive model was derived which incorporated significant predictors of dislocation. An illustrative nomogram translated this predictive model into a usable numerical scoring system called the Children's Hip Prediction score, which estimates probability of hip dislocation. RESULTS There were 97 dislocated hips in 85 patients. The final predictive model included age, sex, family history, breech, gait concerns, decreased abduction, leg length discrepancy, and medical/neurological syndrome. The area under receiver operating curve for the model is 0.761. A Children's Hip Prediction score of≥5 corresponds to a sensitivity of 76.3% and a score of≥15 has a specificity of 97.8%, corresponding to an odds ratio of 27.3 for increased risk of dislocation. CONCLUSION We found that a novel clinical prediction score, based on readily available history and examination parameters strongly predicted risk of dislocations in hip dysplasia referral. It is hoped that this tool could be utilized to optimize resource allocation and may be of particular benefit in less well-resourced health care systems. LEVEL OF EVIDENCE Level II.

Abstract
Developmental dysplasia of the hip (DDH) is the most common congenital abnormality in newborns. Untreated DDH can cause significant impairments, including chronic hip pain, osteoarthritis, limb length discrepancy, altered gait, and joint contractures. Treatment outcomes are significantly worse with increasing delay in presentation, making early screening and detection critical. The purpose of this review is to provide a comprehensive guide for the pediatric primary care provider on the cause, diagnosis, and management of DDH. Screening practices, physical examination, imaging modalities, and treatment will be discussed. A missed hip dislocation in a walking-age child is a devastating but preventable event; pediatric primary care providers should have a high index of suspicion for DDH and promptly refer any patient with concerning findings to a pediatric orthopedic surgeon.

Abstract
INTRODUCTION No consensus exists about the open reduction of developmental dysplasia of the hip (DDH; age of surgery and the need for additional bone surgery). We report clinical and radiological outcomes of a large monocentric study. The objectives are to analyze outcomes and to give recommendations. MATERIALS AND METHODS This was a retrospective review of 414 hips (301 patients) operated on for DDH between 2010 and 2018. The mean age at the time of surgery was 34.6 months (14-96 months). In all, 72 hips had open reduction (OR) alone, 130 had OR with femoral osteotomy, 37 had OR with pelvic osteotomy, and 175 hips OR was associated with femoral and pelvic osteotomy. The mean follow-up was 6.5 years (3-10 years). Clinical outcomes were evaluated according to Mckay's classification. The acetabular index was measured, and Severin classification was used for radiological outcomes. Reduction failure and residual dysplasia were noted, and avascular necrosis of femoral head (AVN) was assessed according to Kalamchi and MacEwen classification. RESULTS At the last follow-up, 331 hips (80.2%) had good clinical results, and 319 (77%) had satisfactory radiological results. The AI measured on the last follow-up radiograph was ≤25° in 350 hips. AVN was noted in 83 hips (20%). Redislocation was founded in 53 hips (12%). Overall: 293 hips (72%) had stable reduction without AVN with good clinical and radiological outcomes. DISCUSSION Clinical outcomes are better and the risk of AVN decreases significantly when a femoral osteotomy is performed. There were better radiological results when pelvic osteotomy was performed. The rate of residual dysplasia was higher when pelvic osteotomy was not performed. We recommend a femoral shortening osteotomy for high dislocations (Tönnis 3 or 4) for children over 18 months and a pelvic osteotomy for children over 36 months or over 18 months with an acetabular index > 25°.

Abstract
BACKGROUND The Petit-Morel method allows the treatment of developmental hip dysplasia in toddlers by combining gradual traction to achieve reduction followed by immobilisation during which pelvic osteotomy is performed. The objective of this study was to assess the radiographic and clinical outcomes in a retrospective cohort of patients. HYPOTHESIS The Petit-Morel method is associated with low rates of avascular necrosis and residual acetabular dysplasia at skeletal maturity, as well as with satisfactory medium-term clinical outcomes. MATERIAL AND METHODS We conducted a single-centre retrospective study of 34 patients (35 hips) treated between 1997 and 2014. The radiological assessment criteria included an evaluation for avascular necrosis classified according to Kalamchi and MacEwan, the vertical centre edge (VCE) angle, femoral head sphericity according to Mose, and acetabular dysplasia at skeletal maturity according to Severin. Hip function was assessed by determining the Postel-Merle d'Aubigné (PMA) score. RESULTS Mean age at treatment was 19±4 months (range, 14-29). Mean follow-up was 11 years (range, 5-20). There were two failures including one case of recurrent dislocation requiring surgical reduction. Group II avascular necrosis occurred in 1 (3%) patient. Tönnis Grade IV dysplasia was significantly associated with resolving irregularity of the ossification centre, seen in 19 (54%) cases (p=0.002). In the 18 patients followed-up to skeletal maturity, with a mean follow-up of 15 years (range, 12-20 years), 17 hips were Severin Class I. The mean VCE angle was 29° (range, 15°-38°), and the head was spherical for 34 (98%) hips. The PMA score at last follow-up was excellent (17-18). The mean VCE angle was greater in all 5 patients who experienced pain during long walks (35° [range, 32°-37°]) than in the asymptomatic patients (28° [range, 15°-38°]) (p=0.009). DISCUSSION The Petit-Morel method is a reliable treatment that provides good clinical and radiological outcomes. Overcorrection of the VCE angle was noted in the patients who experienced walking-related pain in adulthood. LEVEL OF EVIDENCE IV, retrospective observational cohort study.

Abstract
BACKGROUND The purpose of this narrative review was to survey the literature for common complications following treatment of DDH in children less than 4 years old. METHODS The Pubmed database was queried. Search result titles were reviewed to identify papers that were pertinent to the topic. Abstracts for these papers were obtained and read, and a subset of these were selected for review of the complete manuscript. RESULTS 92 manuscripts were reviewed. Residual dysplasia, redislocation, and osteonecrosis are the primary complications of treatment in this age group. In the long term, hips without complications related to DDH treatment tend to do well, although a significant percentage of them will inevitably require joint replacement surgery. CONCLUSION Although there is excellent potential for a good outcome when DDH is diagnosed and treated under age 4 years, osteonecrosis continues to be a concern with all treatment methods. A subset of patients from this young cohort will continue to have residual dysplasia or recurrent dislocation requiring return to the operating room.

Abstract
INTRODUCTION The best treatment option in children with late detected DDH is still a subject of much controversy and only few studies have investigated the long-term outcome of treatment in such patients. We performed a systematic review to assess long-term outcome of late detected DDH hips treated after walking age. METHODS Studies met inclusion criteria if they: (1) reported at least 30 hips treated; (2) included children aged between 9 months and 12 years; (3) treatment indication was late detected DDH after walking age; (4) presented a minimum follow-up of 10 years; (5) reported a clinical or radiological outcome. The Kaplan-Meier method was used to evaluate long-term survival according to clinical and radiological outcomes. The rate of total hip replacement (THR) was retrieved. RESULTS From a total of 6561 articles, 13 articles with grade IV level of evidence were included in our review. A total of 988 hips in 800 patients with a mean follow-up of 27.9 years (range 10-67) were included. The mean age at surgery was 3.3 years (range, 9 months-12 years). The rate of THR increased according to the length of final follow-up. In particular, all studies reported no case of THR at 23.5 years of follow-up, a rate of 10.2% of THR between 30 and 40 years of follow-up and a rate of 35.6% of THR in patients with follow-up more than 40 years. CONCLUSIONS In patients with late detected DDH, most THR became necessary more than 30 years after the index procedure and their number increased further after 40 years and more of follow-up. Late detected DDH diagnosed after walking age is a life-long disease.

Abstract
PURPOSE OF THE STUDY The purpose of the present study is to determine the outcome success of anterior open reduction with Pemberton osteotomy in patients under 18 months of age with developmental dysplasia of the hip. METHODS We retrospectively reviewed the clinical and radiological results of 27 developmental hip dysplasia patients under 18 months of age (26 girls, 1 boy) who underwent anterior open reduction with Pemberton osteotomy. Bilateral surgery was performed in 18 patients and unilateral in nine patients. At the final follow-up, the clinical results were evaluated according to the McKay's clinical evaluation criteria, the radiological results according to the Severin's radiological evaluation criteria, and the presence of avascular necrosis according to the Kalamchi-MacEwen's classification criteria. RESULTS We treated 36 hips of 27 patients who were younger than 18 months of age (range 10-18 months) at the time of surgery and followed up a minimum of 5 years (mean 6.5 years). At the final follow-up, 34 (94.4%) were assessed clinically as excellent, one hip (2.7%) as good and one hip (2.7%) as fair according to the McKay's clinical classification. Radiological classification revealed that, 97.2% of the hips were Severin Type-1 and 2.8% Severin Type-3. Avascular necrosis was observed in 5 of 36 hips (13.8%). Two hips were assessed as Type-2, two hips Type-3 and one hip Type-4 according to the Kalamchi-MacEwen's classification. CONCLUSION We conclude that Pemberton osteotomy with anterior open reduction is useful technique for developmental hip dysplasia treatment of patients under the age of 18 months with good clinical and radiological results as well as with low complication rates.

Abstract
PURPOSE Avascular necrosis (AVN) may occur following treatment for developmental dysplasia of the hip (DDH). The primary aim of this study was to identify the incidence of AVN in a cohort of patients treated for DDH. Secondary aims were to classify AVN using available classification systems, analyze the correlation between the systems and investigate their relationship with the age at diagnosis of DDH. METHODS An 11-year retrospective study was carried out at a single tertiary centre, using data from the clinical portal (patient records database) and IMPAX (system used to store plain radiographic images). Clinical details (patient demographics and outcomes) and plain radiographic images were used to identify cases of DDH and categorize cases of AVN using available classification systems: Tonnis and Kuhlmann, Kalamchi and McEwen, Bucholz and Ogden and Salter. Severin was used to assess final clinical outcome. RESULTS In total, 405 (522 hips) cases of DDH were identified, of which 213 resolved without treatment, 93 were treated conservatively and 99 surgically. Only treated cases were included in the analysis (n = 192). AVN (45/99; 45.5%) was found to occur only postoperatively. A positive correlation was present between age at presentation and severity of AVN as classified according to Salter's criteria (chi-squared p value < 0.01). CONCLUSION AVN incidence was 23.4% (45/192) and only occurred in surgically treated patients. Older age at diagnosis was associated with a higher incidence of AVN, as defined according to Salter's criteria. The classification systems appeared to show no correlation amongst each other (p-value < 0.01). LEVEL OF EVIDENCE III - Retrospective cohort study.

The presence of the ossific nucleus and its relation to avascular necrosis rates and the number of secondary procedures in late-presenting developmental dysplasia of the hip.

Abstract
Late-presenting developmental dysplasia of the hip (DDH) has an incidence reported between 0.07 and 2:1000 live births. Avascular necrosis (AVN) of the femoral head secondary to treatment of DDH is a feared complication and may lead to adverse long-term sequelae. This study aims to investigate the relationship between the ossific nucleus (ON) presence and AVN in late-presenting DDH. This is a retrospective study of prospectively collected data over a 24-year period, at a single UK centre. Late-presenting DDH who were treated surgically with a closed or open reduction were included in the series. The presence of ON was monitored, and outcomes measured included AVN and whether delaying surgery affected the number of secondary procedures. Seventy-six patients with 79 hips (mean age at presentation 13.8 months) were included in the analysis. The mean age at presentation was 13.8 months. About 45.5% of hips with no ON present developed clinically significant AVN (Kalamchi and MacEwen grades 2-4, P = 0.12), compared to 20.6% of hips with the ON present. Delaying surgery did not affect AVN rates or the number of secondary procedures. Looking at long-term outcomes, 86.7% of hips had a Severin grade of I or II and 13.3% had a grade ≥III. Factors that affected long-term outcomes were absent ON (P = 0.04) and open reduction (P = 0.03). In the multiple logistic regression model, only open reduction could increase AVN rates (P value 0.027). The presence of ON at the time of surgery may have an impact on the rate and significance of AVN. Absence of the ON at the time of reduction negatively affects long-term outcomes in late-presenting DDH.

Abstract
BACKGROUND Open reduction with or without pelvic and femoral osteotomy is the accepted treatment option for children older than 18 months with developmental dislocation of the hip (DDH). However, few studies have investigated hip function in children with late DDH treated by open reduction. Therefore, we performed a retrospective study investigating the risk factors potentially associated with unsatisfactory hip function. HYPOTHESIS We hypothesized that some risk factors can be associated with unsatisfactory hip function in patients with late DDH treated by open reduction. PATIENTS AND METHODS We retrospectively reviewed the clinical and radiographic data of 79 children (98 hips, mean age 39.7±18.6 months; range, 19-95.3) with late-detected DDH treated by open reduction. Acetabular index (AI), Tönnis grade, Center Edge Angle (CEA), avascular necrosis of the femoral epiphysis (AVN), and Severin radiographic grade were evaluated on radiographs. Hip function was rated according to modified Outcome Evaluation Standard for Congenital Dislocation of the Hip with a maximum score of 15. According to type of surgery, patients were divided into four groups: open reduction alone (Group A), open reduction in conjunction with pelvic osteotomy (Group B), and open reduction in conjunction with femoral osteotomy and Pemberton/Salter (Group C) or Bernese-type triple pelvic osteotomy (Group D). Analysis of variance (ANOVA), t-test, chi-square test, and multivariate regression analysis were used to evaluate the independent risk factors of unsatisfactory hip function. RESULTS The mean hip function score was 10.8±2.8 (4.5-15); 61 hips (62.2%) had satisfactory function (23 [23.5%] excellent and 38 [38.8%] good), while 37 hips (37.8%) had unsatisfactory function (16 [16.3%] fair and 21 [21.4%] poor). Spearman correlation analysis indicated that age at surgery was negatively correlated with function score (r=-0.326, p=0.001). The age of patients with satisfactory hip function (34.5±14.2 months; range, 19.4-74.8) was significantly lower than those with unsatisfactory function (43.7±21 months; range, 20.6-95.3) (p=0.011). The hip function score in Group A (14.2±0.8; range, 12.8-15) was significantly higher than in the other three groups (p<0.001). Hip function score in patients with type III or IV AVN was significantly lower than those without AVN, or with type II AVN (p=0.001). Multivariate regression analysis confirmed age at surgery, type of surgery and AVN were negatively correlated with hip function score. Logistic regression analysis and chi-square test confirmed age and type of surgery, and AVN were independent risk factors of unsatisfactory hip function. Multivariate regression analysis found ability to squat and amount of hip flexion and abduction, significantly decreased with age at surgery; while presence of limping, amount of hip flexion, abduction, adduction and external rotation significantly decreased with type of surgery. DISCUSSION Age at surgery, type of surgery and severe AVN are independent risk factors for unsatisfactory hip function in patients with late-detected DDH treated by open reduction. The ability to squat, the amount of hip flexion and abduction are the main functional parameters affected by age and surgery. LEVEL OF EVIDENCE IV, case series.

Abstract
INTRODUCTION Developmental dysplasia of the hip (DDH) is a common hip disorder and its association with other musculoskeletal, genetic, and neurological diseases were well described in the literature. Juvenile idiopathic arthritis (JIA) is a rare rheumatological condition, and its presence in a Developmental dysplasia of the hip (DDH) child makes this a very challenging case. PRESENTATION OF THE CASE This case report is describing the presentation of 9 months old girl to orthopedic service referred from the pediatric rheumatology clinic after diagnosing her and starting the treatment for Juvenile idiopathic arthritis (JIA). Bilateral neglected Developmental dysplasia of the hip (DDH) - International Hip Dysplasia Institute (IHDI) type 4- was detected during her clinical and radiological assessment, necessitating surgical management after controlling her Juvenile idiopathic arthritis (JIA). The surgical procedure and its clinical and radiological outcomes more than four years after her surgical treatment are described in detail in this report as well. DISCUSSION The management of Developmental dysplasia of the hip (DDH) associated with Juvenile idiopathic arthritis (JIA) has no established guidelines in literature. Here, we share our experience in managing such rare cases. We believe that medical control of Juvenile idiopathic arthritis (JIA) before proceeding for open reduction of Developmental dysplasia of the hip (DDH) is the key to successful results. CONCLUSION The reported case is uniquely having both Developmental dysplasia of the hip (DDH) and Juvenile idiopathic arthritis (JIA) treated with open reduction, pelvic osteotomy, and femoral shortening resulting in outstanding clinical and radiological outcomes.

Abstract
PURPOSE Despite the early diagnosis and treatment of developmental dysplasia of the hip (DDH), some older children still need open reduction. It is usually difficult to get a satisfactory reduction particularly in patients with acetabular defect. The purpose of this study was to evaluate the short-term outcomes of acetabulum reaming and sartorius muscle pedicle iliac bone grafting in the treatment of older children with DDH and acetabular defect. METHODS The records of 15 patients with DDH (mean age 113.9 months (sd 29); 17 hips) who were treated with the reported technique between February 2015 and January 2017 were retrospectively reviewed. All patients acquired regular clinical and radiographic follow-ups, and alterations in the acetabular index, centre-edge angle and acetabular head index were measured. Joint function and radiographic results were evaluated with McKay and Severin modified criteria, respectively. RESULTS A total of 15 patients were followed up for mean 32.4 months (sd 6.9). The percentages of excellent and good conditions were 94.1% (16/17) according to the Severin modified criteria and 88.2% (15/17) according to the McKay modified criteria. Avascular necrosis of the femoral head and redislocation only occurred in one hip. No cases of ankylosis or bone graft absorption occurred during the follow-up. CONCLUSION Reaming the acetabulum and sartorius muscle pedicle iliac bone grafting for repairing the acetabular defect can recover the arcuate structure by increasing the volume of the acetabulum, which is beneficial for achieving a concentric reduction. The short-term outcome was satisfactory, while the long-term results need to be further observed. LEVEL OF EVIDENCE IV - retrospective study.

[PMID: 32434526 PMCID: PMC7238660 DOI: 10.1186/s13018-020-01700-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 05/06/2020] [Indexed: 11/10/2022] Open
Abstract
Purpose The anterior and medial approaches in open reduction for developmental dysplasia of the hip (DDH) had been widely used. The former could not directly approach the intra-articular interposition, while the latter had been associated with injury to blood vessel and avascular necrosis (AVN) of the femoral head. Meanwhile, the bikini incision had also been mentioned in some studies. The purpose of this study was to introduce a modified anterior approach through a mini-bikini incision and report its short-term outcomes. Methods Data of DDH patients younger than 2 years at the time of surgery who had received this mini-bikini incision between June 2013 and December 2018 were collected. The surgical technique, operation duration, intraoperative blood loss, and length of incision were recorded in detail. In the latest follow up, the objective measurement of the scar and the subjective feeling towards the scar were collected. X-ray and magnetic resonance imaging (MRI) were performed at the last follow-up, and the incidence of residual dysplasia, redislocation, and femoral head AVN was analyzed. Results Forty-three cases (49 hips) were included with an averaged follow-up of 43 months. The operation duration was 22 min, and the blood loss was 9.8 ml on average. The length of the scar averaged 2.6 cm. The mean University of North Carolina “4P” scar scale (UNC4P) for the scar was 0.92, and no patients complained numbness. Overall, all the parents were satisfied with the cosmetic appearance. The mean acetabular index (AI) was 27.42° ± 6.41° in dislocated hip in the last follow-up. One hip redislocated soon after the operation and was reduced in a closed manner right away. MRI showed improved coverage but still some residual dysplasia that was in accordance with the post-operative recovery nature. Four hips (8%) had signs of AVN in X-ray. Conclusion Open reduction through the anterior approach with the mini-bikini incision was a safe procedure with comparable outcomes to classical approaches. It would be a complementary approach for DDH patients younger than 2 years old who need an open reduction.

Abstract
» The treatment of developmental dislocation of the hip after walking age continues to be controversial.» Success can be considered in terms of the rates of osteonecrosis or proximal growth disturbance, the rate of recurrent dislocation, and residual dysplasia.» Case series are small and have many confounders.» The rate of residual dysplasia is lowest after an open reduction and pelvic osteotomy.
