Abstract
PURPOSE We explored the risk factors for avascular necrosis (AVN) after surgery using open reduction, pelvic osteotomy, and femoral osteotomy for Tönnis grade IV developmental dysplasia of the hip (DDH). METHODS In this retrospective study, we collected data of patients with Tönnis grade IV DDH treated with open reduction and pelvic osteotomy combined with femoral osteotomy from January 2012 to May 2020. The patients were divided into the AVN group and non-AVN group using the Kalamchi-MacEwen classification system. The clinical and imaging data of the two groups were collected, and the possible risk factors were included in the analysis. Univariate and multivariate logistic regression analyses were used to identify the independent risk factors and odds ratios of AVN. RESULTS In all, 254 patients (mean age; 2.6±0.9 years, 278 hips) were included. The mean follow-up time was 3.8±1.5 years. A total of 89 hips (32%) were finally classified as AVN (Kalamchi-MacEwen II-IV). Univariate analysis showed significant associations with AVN for age (p=0.006), preoperative femoral neck anteversion (FAV) (p<0.001), femoral osteotomy length to dislocation height ratio (FDR) <1 (p<0.001), and the epiphyseal ossific nucleus diameter to the neck diameter ratio (ENR) <50% (p=0.009). Multivariate logistic regression analysis showed that only excessive preoperative FAV (OR: 1.04; 95% CI: 1.02-1.05; p<0.001) and FDR<1 (OR: 3.58; 95% CI: 2.03-6.31; p<0.001) were independent risk factors for femoral head necrosis. CONCLUSION Excessive preoperative FAV and FDR<1 are important risk factors for femoral AVN after open reduction, pelvic osteotomy, and femoral osteotomy for Tönnis grade IV DDH. For children with DDH with high dislocation and excessive FAV, clinicians should fully evaluate their condition and design more personalized treatment programs to prevent AVN.

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
BACKGROUND Patients with developmental dysplasia of the hip (DDH) have complex proximal femoral deformities, and orthopedic surgery lacks objectivity. Expectations for surgical outcomes are often not achieved, and postoperative problems are common. Using 3D-printed technology in orthopedics offers a novel approach to precise and individualized treatment in modern orthopedics. The aim of this study was to investigate the value of the application of 3D-printed osteotomy guide plates in femoral osteotomy. The clinical indices of femoral osteotomy in children with DDH using 3D-printed osteotomy guide plates were compared with those of traditional osteotomy. METHODS The clinical data of children with DDH who underwent open reduction and Salter pelvic osteotomy combined with femoral osteotomy from September 2010 to September 2020 were retrospectively collected and analyzed. Based on the inclusion and exclusion criteria, a total of 36 patients were included in the study: 16 in the guide plate group and 20 in the conventional group. Operation time (total), operation time (femoral side), X-ray fluoroscopy times (total), X-ray fluoroscopy times (femoral side) and intraoperative blood loss were analyzed and compared between the two groups. Comparison of treatment-related indicators such as postoperative neck-shaft angle, postoperative anteversion angle, hospitalization time, and hospitalization expenses is made between the two groups. The two groups of patients were evaluated at the last follow-up using the McKay clinical evaluation criteria. RESULTS Between the two groups, there were significant differences in operation time (total), operation time (femoral side), X-ray fluoroscopy times (total), X-ray fluoroscopy times (femoral side) and intraoperative blood loss (P < 0.05). The postoperative neck-shaft angle, postoperative anteversion angle, hospitalization time and hospitalization expenses did not differ significantly (P > 0.05). The MacKay clinical evaluation did not significantly differ at the most recent follow-up (P > 0.05). CONCLUSIONS Children with DDH undergoing proximal femoral osteotomy using 3D-printed osteotomy guide plates benefit from a simpler surgical procedure, shorter operative time, less bleeding and less radiation exposure during surgery. This technique is of great clinical value.

Abstract
Introduction: Developmental dysplasia of the hip (DDH) is commonly managed in a tertiary centre and regularly involves surgical treatment. The aim of this study is to determine the surgical outcome of DDH patient treated with either open reduction alone or combined with bony procedures in our institution. Methods: Medical records of DDH patients treated surgically were reviewed. Patients were divided into two groups: Group A: underwent open reduction (OR) only; and Group B: underwent open reduction with additional bony procedures (ORB), such as pelvic or femoral osteotomy. Modified McKay classification was used to evaluate the clinical outcome, and Severin classification for the radiological outcome. Presence of avascular necrosis and other post-operative complications were recorded. Results: A total of 66 patients (76 hips) were reviewed with the mean age of 11.9 ± 4.8 years. Mean duration of follow up was 8.6 ± 4.7 years (ranged 2 to 23 years). From our sample, 50/66 patients (75.8%) achieved satisfactory clinical outcome, whereas 48/66 patients (72.7%) had satisfactory radiological outcome. A higher proportion of patients achieved satisfactory outcomes in the OR group compared to the ORB group (p < 0.05), but no difference was seen in terms of radiological outcome (p = 0.80). Overall, 23 hips (34.8%) developed radiographic evidence of avascular necrosis (AVN). Nineteen hips had undergone ORB, although they were mainly (63.2%) Grade I AVN. Incidence of AVN was comparable in both groups (p = 0.63), but presence of AVN led to a higher proportion of unsatisfactory clinical and radiological outcome (p < 0.05). Other complications included redislocation/subluxation (13.6%) and bleeding (0.1%). Conclusions: Good overall outcome of DDH surgery was achieved in our centre. The OR group may produce a better clinical outcome, but with similar radiological results and AVN rate with the ORB group. The presence of AVN is associated with unsatisfactory clinical and radiological outcomes.

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
The aims of the present study is to evaluate the roles of collagen I and III in the hip capsule in the postoperative clinical function of patients with developmental dysplasia of the hip (DDH). Hip capsules from 155 hips of 120 patients were collected during surgery. The patients were divided into three groups according to age: I: 2-3.5 years; II: 3.5-5 years; and III: 5-6 years. Patient clinical function and radiographic outcomes were evaluated with the McKay scores and Severin classification. The expression of collagen I and III was detected through immunohistochemistry and quantitative reverse transcription polymerase chain reaction (RT-PCR) and analyzed according to age, sex, degree of dislocation and McKay classification. All patients received open reduction and pelvic osteotomy and/or femoral shortening osteotomy and achieved good results on the basis of postoperative X-ray imaging. The average follow-up time was 3.4 years (range 2-4.3 years). There were no changes in the expression of collagen III in the different groups. The expression of collagen I according to age and sex was not significantly different. Lower expression of collagen I was observed in DDH patients with a higher degree of dislocation according to the Tonnis grade. The highest expression of collagen I was detected in the group with poor clinical function according to the McKay classification. Collagen I is correlated with the degree of dislocation and is a risk factor for poor clinical function in DDH patients. Collagen I is correlated with the degree of hip dislocation and poor clinical function in DDH patients.

A randomized controlled trial. INTERNATIONAL ORTHOPAEDICS 2021; 46:589-596.

Abstract
PURPOSE To investigate the necessity of performing capsulorrhaphy during open reduction of DDH. METHODS A single-centre, prospective, randomized controlled trial was conducted between 2015 and 2020. The study included 82 hips in 67 patients with developmental dysplasia of the hip (DDH) who were treated with open reduction via the anterior approach. Patients were randomized into two equal groups (41 hips in each group); group A (capsulorrhaphy was done) and group B (capsulorrhaphy was not done). Dega osteotomy was performed in all cases, while femoral derotation shortening osteotomy was performed only in four hips in group A and four hips in group B. The mean age at the time of surgery was 33 ± 22.3 months. The follow-up period was 24 months for all patients. At the final follow-up, maintenance of reduction was chosen as the primary outcome and was assessed radiologically by the Severin's grading system. Secondary outcome measures were functional evaluation (by using the modified McKay's criteria), Shenton line assessment, acetabular index measurement, and complications. RESULTS According to the Severin's grading system, concentric reduction was achieved in 36 hips in group A and 37 hips in group B, subluxation occurred in three hips in each group, and redislocation was encountered in two hips in group A and one hip in group B. There was no statistically significant difference between both groups (p-value = 0.239). According to the modified McKay's criteria, the results were satisfactory (excellent and good) in 34 hips (82.9%) in group A and 36 hips (87.8%) in group B. The difference was statistically insignificant (p-value = 0.352). The rate of complications was higher in group A (17.1%) than group B (12.2%) (p-value = 0.532). CONCLUSION The stability of the hip joint after open reduction depends mainly on adequate removal of soft tissue obstacles that impede reduction and proper correction of the bony configuration of the hip using pelvic and/or femoral osteotomy. So, the authors believe that capsulorrhaphy is not necessary in the surgical management of DDH, provided that adequate soft tissue and bony gestures are combined.

Abstract
BACKGROUND Developmental Dysplasia of Hip (DDH) presenting at walking age is not uncommon, particularly in developing countries. The available treatment modalities in this age group are closed reduction (CR), open reduction (OR), OR with additional femoral and/or pelvic osteotomy. This study was done in patients who presented between 12 and 36 months of age to assess the following: 1) Percentage of hips amenable for successful CR, 2) failure rate after CR and OR in walking age DDH and 3) the need for secondary procedures to address subluxation and residual dysplasia within first 2 years. METHOD ology: After IRB approval, the institutional database was searched for patients admitted with a diagnosis of DDH from January 2009 to January 2019. We identified 142 patients, of which 65 patients with 84 hips formed the study cohort after applying inclusion and exclusion criteria. Demographic details, details of the interventions, brace wear, revision procedures and radiological data were collected from Hospital Information System. We divided the patients in three groups: Group I - CR, Group II -OR, and Group III - OR with an additional bony procedure in the form of femoral and/or pelvic osteotomy. RESULTS The mean age at presentation was 20.1 months. We had 10 (11.9%) hips in group I, 39 (46.4%) hips in group II and 35 (41.6%) hips in group III. The mean follow-up was 44.8 months (24-132 months). In Group I, 5 (50%) had re-dislocation and 2 (20%) needed revision intervention for residual dysplasia. In Group II, 4 (10%) had re-dislocation and 4 (10%) needed revision intervention. In Group III, 5 (14.2%) hips needed revision intervention for residual dysplasia. The mean final AI was 24.6°in Group I, 28.2° in Group II and 26.3°in Group III. There was no significant difference in the final AI between the groups (p > 0.05). CONCLUSIONS An attempted closed reduction has a 50% failure rate, and we recommend a low threshold for open reduction. There is a 10% rate of re-dislocation following open reduction with or without additional bony procedure. About 50% of the dysplastic hips treated without pelvic osteotomy at the time of index procedure fail to remodel and have residual acetabular dysplasia.

Abstract
Background To evaluate and quantify the intraoperative effect of capsulorrhaphy on the deep seating of femoral head within the acetabulum as measured by medial joint space, a surrogate measure of acetabular-head contact. Methods In order to determine the exact effect of capsulorrhaphy, we prospectively scrutinized a consecutive sample of 18 patients with unilateral dysplastic hips aging > 18 months and followed them for a period of at least 12 months. The procedure of open reduction is described in detail. Two pediatric orthopedists carried out the operations from August 2014 to January 2019 at a tertiary pediatric hospital. Intraoperatively, AP radiographs of the pelvis were obtained before and after capsulorrhaphy. The distance between the inferomedial edge of the proximal femoral metaphysis and the lateral edge of the obturator foramen was recorded. To determine if there were differences in medial joint space due to capsulorrhaphy, a generalized linear model was run on the study sample. All patients were followed for at least 12 months to determine the rate of re-dislocation. Results Mean age (±standard deviation) of the participants was 37.5 (±24.7) months. All cases underwent Salter osteotomy, 5 cases needed femoral shortening (27.8%) and none needed derotational osteotomy. Capsulorrhaphy lead to a statistically significant decrease in the mean medial joint space from 1.59 cm before (95% CI: 1.12–2.05) to 0.76 cm after (95% CI: 0.50–1.02) the capsulorrhaphy (P < 0.001). When we took the effect of age into account the corresponding figures were 1.47 (95% CI: 1.22–1.75) and 0.67 (95% CI: 0.39–0.94), respectively (P < 0.001). After follow up periods of 1 to 5.5 years, none of the patients experienced instability or re-dislocation. Conclusions Capsulorrhaphy, independently, of age was associated with a 1-cm decrease in the mean medial hip joint space and a more deeply seated femoral head. Furthermore, this study presents a successful experience with capsulorrhaphy to prevent hip instability.

Abstract
PURPOSE 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.

Abstract
Purpose This study was performed to assess the clinical and radiological outcomes following one-stage hip reconstruction, consisting of open reduction femoral shortening and pelvic osteotomy, for neglected developmental dislocation of the hip (DDH). Materials and Methods This is a retrospective analysis of 77 hips in 65 patients (46 females and 19 males; 12 had bilateral dislocations), operated at a Ghurki Trust Teaching Hospital in Pakistan between 2013 and 2015. The average age at surgery was 11.02±3.43 years. According to the Tönnis classification, there were 10, 14, 22, and 31 patients in grades 1, 2, 3, and 4, respectively. The pelvic procedure utilized in this study was triple osteotomy (47 hips) followed by double and Salter osteotomy (18 and 12 hips, respectively). Postoperative evaluations were conducted using the modified MacKay's scoring system (functional outcomes) and Severin's scoring method (radiological assessment). Results Postoperatively, there were 38 (49.4%), 19 (24.7%), 14 (18.2%), and 6 (7.8%) hips in Severin grade I, II, III and IV, respectively. According to the modified McKay criteria, there were 22 hips (28.6%) in excellent condition, 44 (57.1%) in good condition, 9 (11.7%) in fair condition and 2 (2.6%) in poor condition. Both patients with poor outcomes had an unstable, painful hip with evidence of avascular necrosis of the femoral head. Conclusion Based on the results presented here, we recommend the single stage procedure of open reduction, femoral shortening and pelvic osteotomy for treatment of DDH in older children with good to excellent functional and radiological outcomes.

Abstract
PURPOSE Patients with late-presenting developmental dysplasia of the hip (DDH) are more likely to require an open reduction. Since many developing countries do not have mandated screening, there continues to be a relatively high incidence of late-presenting DDH. We report the clinical and radiographic outcomes of open reduction in a series of patients who presented late. PATIENTS AND METHODS This was a retrospective review of 712 hips in 645 patients that underwent open reduction, alone or in combination with a pelvic osteotomy. In all, 91 hips had open reduction alone and 621 had open reduction and pelvic osteotomy. Femoral shortening was performed in 221 hips. The mean age at the time of surgery was 2.1 years (1 to 6.5) and the mean follow-up time was 9.3 years (6 to 14). We used the Children's Hospital Oakland Hip Evaluation Score (CHOHES) to determine functional outcomes and the Severin classification was used to evaluate radiographic outcomes. The rate of avascular necrosis (AVN) and the need for a reoperation were also recorded and analyzed. RESULTS In all 80% (570 hips) had good radiographic outcomes (Severin type I or II) and 87% had a CHOHES score of > 90 at final follow up. There was a 14% rate of AVN and only a 2% rate of redislocation. Better radiographic outcomes and lower reoperation rates were seen with patients who underwent both an open reduction and pelvic osteotomy. A trend was observed towards worse outcomes in older patients. CONCLUSIONS There was a high rate of good clinical and radiographic outcomes at a minimum six-year follow-up in patients with late-presenting DDH who underwent open reduction. Those who underwent open reduction in combination with a pelvic osteotomy had a higher rate of good radiographic outcomes and a lower rate of complications, particularly reoperation.

Abstract
Objective: To document the clinical presentation of neglected DDH and evaluate the outcome of triple procedure. Methods: It was a descriptive case series study, conducted at the Department of Orthopedic Surgery, National Institute of Rehabilitation Medicine (NIRM), Islamabad over a period of 8-years. It included children aged >1 and <9 years who underwent the triple procedure of open reduction, femoral shortening and Salter’s osteotomy. Clinical evaluation was performed using McKay’s criteria. Tonnis classification and Severin’s scoring system were employed for the radiological evaluation. Results: There were 193 children with 213 DDH affected hips. The mean age was 3.31±1.6 years. The preoperative severity of the femoral head dislocation per Tonnis classification was Grade-I in 7.98%(n=17), Grade-II in 48.35%(n=103) and Grade-III in 43.66%(n=93) hips. The postoperative MacKay criteria was ’Good’ to ’Excellent’ in 193(90.61%) hips. The postoperative Severin’s class was I in 113(53%) hips, II in 48(22.53%) hips, III in 43(20.18%) and IV in 9(4.22%) hips. The preoperative acetabular index ranged from 39° to 51° with a mean of 43.91±3.69°. The mean postoperative AI was 18.42±2.99°. The postoperative centre edge angle ranged from 21° to 26° with a mean 23.18 ±1.35°. Conclusions: The single stage triple procedure offers the surgical remedy of choice with favourable results for managing neglected and late diagnosed DDH among children aged 1-8 years.

Abstract
INTRODUCTION Bernese-type triple pelvic osteotomy (BTPO) combines periacetabular and triple innominate osteotomy techniques. However, studies that evaluate the clinical and radiographic outcomes of BTPO are scarce. The aim of this study is to report on the clinical and radiographic outcomes of ambulatory children with developmental dysplasia of the hip (DDH) or Legg-Calvé-Perthes disease (LCPD) managed with BTPO that were older than five years of age at the time of surgery. MATERIALS AND METHODS We retrospectively reviewed the records of 27 consecutive patients with DDH or LCPD (mean age 7.6 ± 1.8; 28 hips) who were treated with the reported technique. All patients had regular clinical and radiographic follow-up. Post-operatively, changes in the acetabular index (AI) and centre-edge angle of Wiberg (CEA) were measured in all patients. The presence/absence of avascular necrosis of the femoral epiphysis was also noted in patients with DDH. Final radiographic results were evaluated with the Severin and Stulberg classifications. The Harris hip score was used in the functional evaluation of all patients. RESULTS In patients with DDH, the mean age at the time of surgery was 7.5 ± 1.8 years and the mean follow-up time was 22.2 ± 10.7 months. Prior to surgery, the mean AI was 37.9° ± 7.6°. At their final follow-up visit, the mean AI and CEA were 10.8° ± 5.4° and 40.9° ± 8.6°, respectively. Moreover, 66.7% of hips (14/21) were graded as Severin type I, and 33.3% (7/21) were graded as type II. The overall AVN rate was 14.3% (3/21). The mean Harris score was 92.1 ± 7.7. In patients with LCPD, the mean age at the time of surgery was 7.9 ± 1.8 years, and the mean follow-up time was 18.4 ± 6.1 months. Prior to surgery, 85.7% of hips were graded as Herring C, and 14.3% were graded as grade B. Prior to surgery, the mean AI and CEA were 19.4° ± 5.3° and 19.1° ± 12.6°, respectively. At the final follow-up visit, the mean AI and CEA were 5.8° ± 3.4° and 50.3° ± 12.0°, respectively, and 57.1% of hips were graded as Stulberg II. The mean Harris score was 94 ± 5.4. Ischial osteotomy non-unions were recorded in three patients (10.7%). CONCLUSIONS BTPO through a modified anterior Smith-Peterson approach is an alternative treatment for DDH and LCPD in older children who are skeletally immature. It not only provides for a large acetabular correction but also achieves good biomechanical stability.

Abstract
BACKGROUND Anterior open reduction is commonly used to treat hip subluxation or dislocation in developmental dysplasia of the hip (DDH) in walking-age children. Pelvic and/or femoral osteotomy may be used in addition, but it is unclear how this affects avascular necrosis (AVN) risk and radiological and clinical results. QUESTIONS/PURPOSES The purpose of this study was to review studies of walking-age patients treated either with an open reduction alone or combined with pelvic and/or femoral osteotomies and determine whether there is a difference between groups in the proportion of patients: (1) developing clinically relevant femoral head AVN (Kalamchi & MacEwen Types II to IV or equivalent); (2) achieving a satisfactory radiological result (Severin Grade I/II or equivalent); (3) achieving a satisfactory clinical result (McKay excellent or good rating or equivalent); and (4) requiring further nonsalvage surgery. METHODS MEDLINE, Embase, the Cochrane Centre Register of Controlled Trials, and ClinicalTrials.gov were searched for studies of anterior open reduction for DDH in children aged 12 months to 6 years old. We assessed AVN, clinical and radiological results, and requirement for further procedures. The effect of failed conservative management, traction, age at operation, and followup duration was also assessed. Eighteen studies met the review eligibility criteria. RESULTS Open reduction alone had a lower risk of AVN than open reduction combined with pelvic and femoral osteotomy (4% versus 24%), but there was no significant difference compared with open reduction with either pelvic (17%) or femoral osteotomy (18%). More hips treated with open reduction alone had satisfactory radiological results than open reduction combined with pelvic and femoral osteotomy (97% versus 83%) and satisfactory clinical results than all other interventions. More hips treated with open reduction alone required further surgical management (56%) compared with open reduction and pelvic osteotomy (11%) and combined pelvic and femoral osteotomies (8%). CONCLUSIONS Open reduction with concomitant pelvic osteotomy is the most appropriate option to provide durable results with the lowest risk of AVN and best radiological and clinical results. There is no evidence that addition of a femoral osteotomy provides any additional benefit to the patient, although it may be necessary to achieve reduction. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
The term “developmental dysplasia of the hip” (DDH) includes a wide spectrum of abnormalities that affect the hip during its growth, ranging from dysplasia to joint dislocation and going through different degrees of coxofemoral subluxation. The incidence of DDH is variable, and depends on a number of factors, including geographical location. Approximately one in 1,000 newborn infants may present hip dislocation and around 10 in 1,000 present hip instability. Brazil has an incidence of five per 1,000 in terms of findings of a positive Ortolani sign, which is the early clinical sign for detecting the disorder. The risk factors for DDH include: female sex, white skin color, primiparity, young mother, breech presentation at birth, family history, oligohydramnios, newborns with greater weight and height, and deformities of the feet or spine. Hip examinations should be routine for newborns, and should be emphasized in maternity units. Among newborns and infants, the diagnosis of DDH is preeminently clinical and is made using the Ortolani and Barlow maneuvers. Conventional radiography is of limited value for confirming the diagnosis of DDH among newborns, and ultrasound of the hip is the ideal examination. The treatment of DDH is challenging, both for pediatric orthopedists and for general practitioners. The objectives of the treatment include diagnosis as early as possible, joint reduction and stabilization of the hip in a secure position. Classically, treatment options are divided according to different age groups, at the time of diagnosis.

Abstract
INTRODUCTION A combined procedure including open reduction, femoral shortening osteotomy, and an acetabular procedure is often necessary to obtain a desirable result in children of walking age who have a high-riding hip dislocation. STEP 1 SURGICAL APPROACH A careful approach to the femoral head and acetabulum is required to avoid injury to nerves, vessels, and cartilage. STEP 2 EXPLORE THE HIP JOINT Make sure to find the true acetabulum and remove all obstacles to femoral head reduction. STEP 3 FEMORAL HEAD REDUCIBILITY Check the reducibility of the femoral head in different positions through a full range of hip motion. STEP 4 FIRST FEMORAL OSTEOTOMY Expose the proximal part of the femur subperiosteally and make necessary markers for determining the amount of shortening and rotation at the time of osteotomy. STEP 5 HIP JOINT STABILITY Check femoral head reduction stability with the proximal end of the osteotomized femur. STEP 6 FEMORAL SHORTENING Decide the amount of shortening and rotation for the best femoral head reduction. STEP 7 PEMBERTON ACETABULOPLASTY In cases with a dysplastic acetabulum and inadequate femoral head coverage after reduction, perform a Pemberton osteotomy. STEP 8 POSTOPERATIVE MANAGEMENT Apply a hip spica cast, which the patient wears for six weeks; then switch to a hip abduction brace. RESULTS The patient shown in Figures 26 through 29 and Video 5 was a three-year and six-month-old girl with bilateral developmental dysplasia of the hip that was discovered late (Figs. 26 and 27).IndicationsContraindicationsPitfalls & Challenges.

Abstract
Background The one-stage procedure for treatment of older developmental dislocation of the hip (DDH) is used widely. However, the best age group for this operation is still unknown. The aims of our study were to evaluate middle-term outcomes of one-stage surgical treatment of a large number of patients with late-diagnosed DDH, and to explore the best age group for treatment. Methods We retrospectively reviewed 652 patients with a total of 864 hip joints with DDH, all aged >18 months. All the hip joints were treated with one-stage procedures including open reduction, pelvic osteotomy, and femoral shortening. The patients were divided into three groups according to age at surgery: Group I: 1.5–2.5 years; Group II: 2.5–8 years; and Group III: >8 years. The latest clinical and radiographic outcomes, complications and avascular necrosis (AVN) of the femoral head were evaluated and compared among the three groups. Results The mean age at surgery was 5.8 years (range: 1.5–13.2 years). The average time of follow-up was 6.2 years (range: 3.2–8.9 years). A total of 79.4% of good or excellent outcomes were obtained for clinical functional evaluation according to the McKay classification. For radiographic outcomes, 732 hips (84.7%) were classified as good or excellent according to the Severin classification. A total of 27.4% of all hips had a poor outcome according to the Kalamchi and MacEwen classification for AVN. The poorest outcomes were observed for clinical, radiographic and AVN results in Group III (p < 0.001). Compared with Group I, the better results for clinical and AVN outcomes were found in Group II (p < 0.001). However, similar clinical outcomes were observed between Groups I and II (p > 0.05). A significantly higher incidence of redislocation and residual acetabular dysplasia was observed in Tonnis grade II and III hip dislocation (p < 0.001). Conclusions One-stage treatment of late-diagnosed DDH had a good outcome in young and middle group. Younger patients achieved better results than older patients. However, the best age group was 2.5–8 years. Tonnis grade II and III DDH is a risk factor for redislocation and residual acetabular dysplasia after the one-stage operation.

Abstract
Despite the screening programs for newborn children with hip ultrasonography, neglected developmental dysplasia of the hip (DDH) is still continuing to be a problem in the east and southeast parts of our country. The main complications are redislocation, avascular necrosis, and joint stiffness. We present an unusual complication, femoral neck fracture during passive motion under general anesthesia, of a six-year-old girl with neglected DDH treated by open reduction and Pemberton osteotomy without femoral shortening. The fracture was treated by open reduction and internal fixation combined with proximal femoral shortening. After 5 years the patient had excellent clinical results, no avascular necrosis was seen, and the radiologic appearance was type IA according to modified Severin classification. In conclusion older children with neglected DDH are more likely to have joint stiffness after open reduction. If there is even a little doubt about joint stiffness after open reduction, one should not refrain from femoral shortening. Also passive motion under general anesthesia should be applied very carefully with fluoroscopic control.

Abstract
BACKGROUND The surgical management of developmental dysplasia of the hip (DDH) in older children has been the subject of controversy. The purpose of this study was to evaluate the outcome in patients with neglected DDH who underwent individual procedures based on using three-dimensional computed tomography. METHODS Forty-seven patients (59 hips) were treated using Pemberton osteotomy or Dega plus Pemberton osteotomy. Subtrochanteric transverse femoral shortening and derotation osteotomy were performed for all patients. The average age at the time of surgery was 10.5 y for group 1 (bilateral dislocation, 24 hips) and 11.2 y for group 2 (unilateral dislocation, 35 hips). Mean follow-up was 5.3 y for group 1 and 5.8 y for group 2. RESULTS At the end of follow-up, 13 hips (54.2%) were rated excellent, eight hips (33.3%) were good, and three hips (12.5%) were fair in group 1. In group 2, 20 hips (57.1%) were rated excellent, 10 hips (28.6%) were good, and five hips (14.3%) were fair. There were five patients who had a limb length discrepancy of approximately 1.5 cm in group 2. Six hips in group 1 and seven hips in group 2 had osteonecrosis of varying severity. CONCLUSIONS We believe that preoperation three-dimensional computed tomography evaluation, personalized operation plans, and experience with the surgical procedure are the main reasons for the satisfactory therapeutic effects achieved in this study in older children with DDH.

Abstract
Objectives to evaluate the radiographic results from patients with bilateral developmental dysplasia of the hip (DDH) who underwent surgical treatment by means of open reduction and Salter osteotomy, with or without associated femoral shortening as described by Ombrédanne. Methods this was a retrospective descriptive study in which 21 patients with bilateral DDH (42 hips) were analyzed. They were treated at Hospital Infantil Joana de Gusmão (HIJG), with operations between August 1997 and October 2009. To evaluate the radiographic results, the acetabular index and the Wiberg center-edge angle were measured, and the Severin and Kalamchi–MacEwen classifications were used. Descriptive and parametric statistical analyses were used to evaluate the data. Results we did not observe any statistically significant difference in analyzing the radiographic parameters, making comparisons regarding the side affected, the order of the procedures and whether femoral shortening was performed, although there was a significant difference between them from before to after the operation. Conclusion open reduction in association with iliac osteotomy as described by Salter presented significant improvements in the radiographic parameters analyzed, comparing the pre- and postoperative values. This improvement occurred independently of whether Ombrédanne femoral shortening was performed. The most prevalent complication in the study group was avascular necrosis of the femoral head.

Abstract
UNLABELLED We evaluated treatment results of 22 children (32 hips) with idiopathic hip dislocation after walking age in two Dutch academic hospitals. The Tönnis classification was used preoperatively. Outcome was measured using the Severin and Kalamchi classification. The mean age at treatment was 24 months and the mean follow-up was 6.8 years. In 24 hips (73%), a perfect outcome was found (Kalamchi score≤1 and Severin score of 1). A fair or a poor outcome according to Severin (≥3) was found in five hips (15%). Treatment of a hip dislocation beyond 18 months of age usually results in adequate hip development with limited avascular necrosis. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND The principles of treatment of congenital dislocation of hip in old children are different than those of infants and neonates. The purpose of this study is to evaluate the radiographic and functional results of one-stage treatment (open reduction, femoral shortening derotation, and Salter's osteotomy) of DDH in older children. MATERIALS AND METHODS Between January 2005 and June 2010, 25 patients (30 hips) underwent one-stage triple procedure of open reduction, femoral shortening derotation, and Salter's osteotomy for the treatment of DDH. Preoperatively, they were classified according to the Tönnis class. Clinical outcomes were assessed using the modified McKay's criteria to measure pain symptoms, gait pattern, Trendelenburg sign status, and the range of hip joint movement. Radiographic assessment was made using Severin's scoring method to measure the centre-edge angle and dysplasia. RESULTS The mean age at the time of operation was 3.9 years (range 1.6-8 years), and the average duration of followup was 4.1 years (range 2-7.6 years). The McKay's score was excellent in 13 hips, good in 14 hips, fair in 2, and poor in 1 hip. The Severin's class I and II was found in 25 (83.3%) hips at the time of final evaluation as compared to none at the time of presentation. CONCLUSIONS Young children having DDH can safely be treated with an extensive one-stage triple procedure of open reduction, femoral shortening derotation, and Salter's osteotomy, without increasing the risk of AVN. Early diagnosis and intervention is the successful treatment of patients suffering from DDH.

Abstract
Objective Using biomechanical studies, this research aims to compare hip capsulorrhaphy in rabbits, carried out with two different techniques: capsulorrhaphy with simple sutures and with anchors. Method Thirteen New Zealand Albino (Oryctolaguscuniculus) male rabbits, twenty-six hip joints, were used. First, a pilot project was performed with three rabbits (six hip joints). This experiment consisted of ten rabbits divided into two groups: group 1 underwent capsulorrhaphy on both right and left hips with simple suture using polyglycolic acid absorbable thread, and group 2 underwent capsulorrhaphy with titanium anchors. After a four-week postoperative period, the animals were euthanized and the hip joints were frozen. On the same day of the biomechanical studies, after the hip joints were previously unfrozen, the following parameters were evaluated: rigidity, maximum force, maximum deformity and energy. Results There was no relevant statistical difference in rigidity, maximum force, maximum deformity and energy between the simple suture and anchor groups. Conclusion Through biomechanical analyses, using parameters of rigidity, maximum force, maximum deformity and energy, it has been shown that capsulorrhaphy with simple suture and with anchors has similar results in rabbit hip joints.

Abstract
BACKGROUND The favorable results of Pemberton acetabuloplasty in children with developmental dysplasia of the hip have been well reported. We reviewed our long-term results related to osteonecrosis of the femoral head after this surgery, especially with regard to the effect of excessive inferior displacement of the femoral head. METHODS From 1993 to 1997, we performed 167 Pemberton acetabuloplasties in patients with developmental dysplasia of the hip who were eighteen months of age or older. Patients who had had prior treatment or developmental dysplasia of the hip due to neuromuscular disease were excluded. We selected patients who had unilateral developmental dysplasia of the hip, had undergone simultaneous open reduction and Pemberton acetabuloplasty between the ages of eighteen and thirty-six months, and had been followed for a minimum of ten years. Forty-nine patients met these criteria. The patients were divided into osteonecrosis-absent and osteonecrosis-present groups according to the criteria described by Kalamchi and MacEwen. Preoperative, interim follow-up and final radiographs were available for evaluation, as were the results of clinical examination. We used the femoral head inferior displacement percentage, measured on the radiographs, to quantify the amount of excessive correction postoperatively. Outcomes were measured with use of the McKay criteria and the Severin criteria. RESULTS The mean age at the time of surgery was 20.8 months, and the mean duration of follow-up was 134.6 months. Twenty-four patients (49%) were classified as not having osteonecrosis (the osteonecrosis-absent group) and twenty-five patients (51%), as having osteonecrosis (the osteonecrosis-present group). There were no significant differences between the two groups in terms of sex, age, laterality, Tönnis grade, or preoperative acetabular index. Seven of the cases of osteonecrosis were type I, thirteen were type II, one was type III, and four were type IV. The inferior displacement percentage revealed significant differences between the two groups (p < 0.0001). In the osteonecrosis-absent group, 96% of the patients had a radiographically satisfactory result (Severin class I or II); however, only 76% of the patients in the osteonecrosis-present group had a radiographically satisfactory result (p < 0.0001). According to the McKay criteria, there were significant clinical differences between the groups (p < 0.0001). CONCLUSIONS Our results showed significant correlation between excessive reduction of the femoral head and the development of osteonecrosis. In light of the high prevalence of type-II osteonecrosis, we postulated that the lateral epiphyseal branch of the medial circumflex artery was vulnerable to compression with increased inferior displacement of the femoral head. The latest radiographic and functional results corresponded to the severity of the osteonecrosis.

Abstract
OBJETIVO: Avaliar os resultados do tratamento cirúrgico da Displasia do Desenvolvimento do Quadril na idade da marcha. MÉTODOS: Avaliamos 33 quadris operados entre novembro de 1992 e setembro de 1997. A média de idade foi 4 anos e 5 meses na ocasião da cirurgia e 11 anos e 7 meses quando avaliamos os resultados. O seguimento médio foi de 10 anos e 2 meses. Realizamos o encurtamento femoral, redução cruenta e osteotomia pélvica (Salter ou Chiari). Radiograficamente avaliamos: grau da luxação, índice acetabular; ângulo acetabular; arco de Shenton; linha de Hilgenheiner; coeficientes c/b, c/h, centro-acetábulo e cabeça-acetábulo; largura da cartilagem trirradiada; relação cabeça trocânter; esfericidade da epífise femoral; ângulo de Wiberg; necrose avascular e anisomelia. Os parâmetros radiográficos foram avaliados nos períodos pré-operatório, pós-operatório imediato e tardio. RESULTADOS: Verificamos estatisticamente melhora significante destes no momento pré-operatório para o pós-operatório imediato (p=0,0001) porém não houve variação significante entre o pós-operatório imediato e o tardio (p=0.5958). CONCLUSÃO: Pela classificação utilizada para avaliação dos resultados observamos 23 (69,70%) bons, 5 (15,15%) regulares e 5 (15,15%) maus resultados.

Abstract
BACKGROUND Joint-preserving reconstructive surgeries in children and adolescents remain challenging for orthopaedists with regard to indication and surgical technique. Besides skeletal maturity and tissue quality at the time of surgery, the kind and degree of deformity, the causative pathologies in secondary dysplasias, and the prognosis have to be considered when deciding for or against a surgical procedure. Developmental dysplasia of the hip (DDH) is the most frequent deformity that indicates reorienting surgery on the hip joint in children and adolescents. The aim of these procedures is to prevent early secondary osteoarthritis. For patients and families as well as for the orthopaedist, risk-benefit analysis is of major interest. METHODS In this study, the surgical techniques and specialties of different reconstructive operations are presented. Based on a review of the literature, the results of defined surgical methods are discussed and compared with own experiences. RESULTS Only limited information is available about the clinical long-term outcome after defined reconstructing surgery on the hip joint in children and adolescents. The degree of the deformity, the age of onset, and the surgical experience of the orthopaedist are crucial factors in decision making for or against a surgical treatment. In early childhood, acetabuloplasty and Salter osteotomy are widely accepted to correct DDH. Triple and periacetabular osteotomies are preferred and have shown promising results in late adolescence and young adults. When the triradiate cartilage (growth plate) is closed, good outcomes can be achieved by the Ganz osteotomy. Intertrochanteric varus and derotation osteotomies of the femur may serve as additional procedures for pelvic osteotomies and are rarely indicated as a single procedure today. CONCLUSION Reconstructive surgery on the hip joint improves function and may prevent early osteoarthritis and delay progression of cartilage degeneration in most patients when the indication and surgical technique are appropriate.

Abstract
UNLABELLED The surgical treatment of patients with neglected developmental dysplasia of the hip (DDH) has been the subject of controversy. We asked if age affected outcome in patients with neglected DDH with unilateral or bilateral dislocation who underwent one-stage combined procedures. We retrospectively reviewed the results of 40 patients (51 hips) treated with a one-stage combined procedure consisting of open reduction, pelvic osteotomy, and femoral shortening. The average age at the time of surgery was 5.4 years for Group I (bilateral dislocation, 22 hips) and 6.7 years for Group II (unilateral dislocation, 29 hips). Mean followup was 5.4 years for Group I and 6.7 years for Group II. According to the modified score system of Trevor et al, 13 hips rated excellent, three were good, and six were fair in Group I; the ratings were 14, nine, and six hips respectively in Group II. Four patients had a limb-length discrepancy of approximately 1.5 cm in Group I. Twelve hips in Group I and 18 hips in Group II had osteonecrosis of varying severity. Our data suggest the outcomes of the children who were 5.5 years or younger in Group I and 8 years or younger in Group II were better. LEVEL OF EVIDENCE Level IV, case series.
