Dysplasia Of The Hip

Developmental dysplasia of the hip (DDH) is a one of the most common congenital abnormalities. It presents with the wide spectrum of anatomical features due to the mild or incomplete formation of the acetabulum leading to laxity of the joint capsule, secondary deformity of the proximal femur head and irreducible hip dislocation. It present with an estimated incidence ranging from 1.4 to 35.0 per 1000 newborns with higher prevalence in Asian, Mediterranean, Caucasian, and American populations with a sex-ratio of girls to boys as 4-10:1. The risk of complications after treatment is associated with the type of reduction and also depends of previous treatment and immobilization, degree of dislocation, patient’s age at surgery. This study is a cross-sectional study with DDH patients born between January 2018 and December 2019, in the city of Al Najaf, Iraq. Ethnicity, gender, fetal presentation, time of diagnosis, affected side of the hip, family history and avascular necrosis of the femoral head (AVN) complications were considered. Post-operative clinical and radiological evaluation was preformed depending on McKay’s criteria and Severin’s classification. A total of 49 DDH patients were identified with female:male ratio of 7,2:1. Among girls, the time of diagnosis was 2,68 ±1,14 years, in the group of boys this indicator was 3,4 ±1,02 years, р=0,231. In both gender group the bilateral process was most common (66,7% in male group and 58,9% in female group). In 30% patient the family history was positive. Normal vaginal delivery was in 69,4% cases (67,4 and 83,3% girls and boys). Breech presentation was observed exclusively in female group. In 14% cases a combination of DDH with other malformations was revealed, in most cases it was joint laxity, less common minor congenital malformations. In 30% patients the closed bilateral reduction was performed. 46 patients were undergoing open reduction. Complications of DDH were detected in 29% cases. Most common was avascular necrosis in varying degrees (35%), 14% patients had early osteoarthritis, 21% local infections. The post-operative clinical McKay’s criteria showed prevalence of excellent and good results. Findings of the post-operative radiographic assessment (Severins grade method) were excellent in 21 hips, good in 14 hips. Сonsequently, late diagnosis of DDH leads worth outcomes, requires surgical interventions and causes increasing frequency of complications.

Objective Closed reduction (CR) is a noninvasive treatment for developmental dysplasia of the hip (DDH), and this treatment is confirmed intraoperatively. This study aimed to develop a preoperative estimation model of the probability of requiring open reduction (OR) for DDH. Methods The study design was cross-sectional by screening all patients younger than 2 years who had attempted CR between October 2012 and July 2016 by a single surgeon. Potential diagnostic determinants were sex, age, side, bilaterality, International Hip Dysplasia Institute (IHDI) grade, and acetabular index (AI). An intraoperative arthrogram was the reference standard. A logistic regression equation was built from a reduced model. Bootstrapping was performed for internal validity. Results A total of 164 hips in 104 patients who met the inclusion criteria were analysed. The prevalence of CR was 72.2%. Independent factors for OR were older age, higher IHDI grade, and lower AI. The probability of OR = 1/[1 + exp − (−2.753 + 0.112 × age (months) + 1.965 × IHDI grade III (0 or 1) + 3.515 × IHDI grade IV (0 or 1) − 0.058 × AI (degrees)]. The area under the curve was 0.79. Conclusion This equation is an objective tool that can be used to estimate the requirement for OR.

Dysplasia Of The Hip

The term ‘developmental dysplasia of the hip’ (DDH) includes a wide spectrum of hip alterations: neonatal instability; acetabular dysplasia; hip subluxation; and true dislocation of the hip. DDH alters hip biomechanics, overloading the articular cartilage and leading to early osteoarthritis. DDH is the main cause of total hip replacement in young people (about 21% to 29%). Development of the acetabular cavity is determined by the presence of a concentrically reduced femoral head. Hip subluxation or dislocation in a child will cause an inadequate development of the acetabulum during the remaining growth. Clinical screening (instability manoeuvres) should be done universally as a part of the physical examination of the newborn. After two or three months of life, limited hip abduction is the most important clinical sign. Selective ultrasound screening should be performed in any child with abnormal physical examination or in those with high-risk factors (breech presentation and positive family history). Universal ultrasound screening has not demonstrated its utility in diminishing the incidence of late dysplasia. Almost 90% of patients with mild hip instability at birth are resolved spontaneously within the first eight weeks and 96% of pathologic changes observed in echography are resolved spontaneously within the first six weeks of life. However, an Ortolani-positive hip requires immediate treatment. When the hip is dislocated or subluxated, a concentric and stable reduction without forceful abduction needs to be obtained by closed or open means. Pavlik harness is usually the first line of treatment under the age of six months. Hip arthrogram is useful for guiding the decision of performing a closed or open reduction when needed. Acetabular dysplasia improves in the majority due to the stimulus provoked by hip reduction. The best parameter to predict persistent acetabular dysplasia at maturity is the evolution of the acetabular index. Pelvic or femoral osteotomies should be performed when residual acetabular dysplasia is present or in older children when a spontaneous correction after hip reduction is not expected. Avascular necrosis is the most serious complication and is related to: an excessive abduction of the hip; a force closed reduction when obstacles for reduction are present; a maintained dislocated hip within the harness or spica cast; and a surgical open reduction.Cite this article: EFORT Open Rev 2019;4:548-556.

Dysplasia Of The Hip

Introduction: Besides an effective screening method for developmental dysplasia of the hip, there is certain number of children in whom the condition has been overseen or they have never been screened and the parents have noticed the odd walking pattern in their toddler. Treatment of such patients is controversial. One of the recommended treatment methods because of the short-term hospitalization, but often considered unsuccessful is closed reduction of the hip followed by cast immobilization. Hypothesis: Closed hip reduction in late diagnosed developmental dysplasia of the hip gives good results.  Aim: Our aim in this retrospective study was evaluation of the success of the treatment with closed reduction of hip dislocation in children older than 12 months.  Patients and methods: In the study, we included 20 patients treated at our clinic from June 2004 to May 2017. Of these 20 patients, 8 had bilateral involvement, 12 had unilateral, in a total of 28 hips. In all patients we noted preoperatively the range of movement, the presence of limp, any limb inequality, and hip pain. We used clinical and radiological parameters for evaluation. Clinically, we examined the range of movement, limb inequality as well as limb function and we classified it according to the modified McKay’s criteria. Same examinations were done at 1, 3, and 5 years after closed reduction. Results: At the last follow-up examination, using McKey’s criteria for clinical evaluation we rated the hips in two patients (7%) as grade III, i.e. fair grade, 10 hips (36%) were grade II – rated good, and 16 hips (57%) were evaluated as grade I. In four hips, there were signs of avascular necrosis of the hip, while in one patient the avascular necrosis developed after the closed reduction. Radiographic assessment (Figs 3, 4) using Severin’s scoring system showed no hips with types V and VI, type IV was observed in 7%, type III in 21%, type II in 29%, while most of the hips (12, 43%) were type I. Conclusion: We concluded that the procedure was justified. An advantage of this method is that it is inexpensive; it entails no direct operative changes of the bone structures and gives good results.

BACKGROUND: Studies investigating the association between developmental dysplasia of the hip (DDH) and risk factors in Saudi Arabia are rare. OBJECTIVE: Investigate the association between DDH and several risk factors among Saudi children. METHODS: The medical records of 82 children born in or admitted to King Abdul Aziz Medical City in Riyadh, Saudi Arabia with clinical suspicion of hip dislocation (HD) were included. The association between DDH and the following risk factors was investigated: age < 3 y, female-gender, twinning, first-born child, C-section, breech presentation, prematurity, positive family history and presence of associated abnormalities. RESULTS: HD was confirmed in 73 (89%) children (Positive HD) and excluded in 9 (11%) children (Negative HD). Eleven (13.4%) children were excluded from the positive cases as it was confirmed that they have paralytic hip dislocation not DDH. DDH was confirmed in 62 children (75.6%). The Chi square test (χ2) and odds ratios (OR) revealed that the positive family history, female-gender, age < 3 years, and presence of associated abnormalities had significant associations with the presence of DDH with P values and OR equal 0.00 (16.4), 0.002 (3.1), 0.005 (2.6), and 0.04 (1.9) respectively. Breech presentation, twinning, first-born children, prematurity, and C-section were not associated with DDH with P values and OR equal 0.93 (1.1), 0.46 (0.4), 0.11 (0.4), 0.08 (0.3), and 0.002 (0.3) respectively. CONCLUSIONS: Positive family history, female-gender, age < 3 years, and presence of associated abnormalities had approximately 16, 3, 2.5, and 2 times increased risk for DDH.

Introduction The aim of this study was to define the clinical indications and demographic characteristics of patients undergoing open reduction for developmental dysplasia of the hip (DDH), and determine the proportion due to preventable failures of contemporary clinical screening and early management. Methods Case notes were reviewed of consecutive primary open reductions performed for non-teratologic hip dislocation at the Great Ormond Street Hospital for Children over a five-year period. Forty-eight patients (64 hips) were suitable for inclusion. A telephone survey confirmed selective hip ultrasonography screening protocols were employed in all maternity hospitals in our referral base. Results There were no cases of open reduction for unilateral DDH following Pavlik treatment commenced by six weeks of age, highlighting the importance of early detection and treatment. Eleven cases (23%) may have been avoided by appropriate implementation of existing selective ultrasonography screening protocols. Thirty-four cases (71%) presented after four months of age, suggesting open reduction is associated with late diagnosis rather than failure of primary management. None of these patients had neonatal hip ultrasonography and only 12% (4 patients) had a risk factor that should have triggered a scan. Conclusions Compared with published results, the contemporary screening practices in our referral base are failing to eliminate late presenting DDH and the need for open surgical reduction. Changes in strategy and implementation are required to significantly improve screening efficacy.

Dysplasia Of The Hip

Developmental dysplasia of the hip (DDH) is one of the most prevalent congenital malformations. It has a wide spectrum of anatomical abnormalities of the hip joint and is characterized by mild or incomplete formation of the acetabulum leading to laxity of the joint capsule, secondary deformity of the proximal femur and irreducible hip dislocation. It is the leading cause of early hip osteoarthritis in young individuals. Both genetic and environmental factors have been proposed to play an important role in the pathogenesis of DDH. A high prevalence is present in Asian, Caucasian, Mediterranean and American populations, with females being more frequently affected. We evaluated a variety of genetic studies indexed in the PubMed database. Several susceptive genes, including WISP3, PAPPA2, HOXB9, HOXD9, GDF5, TGF Beta 1, CX3CR1, UQCC, COL1A1, TbX4 and ASPN have been identified as being associated with the development of DDH. Moreover, genetic association has also been reported between hip dysplasia and other comorbidities. Even though genetic components are a crucial part in the aetiology of DDH, several DDH susceptibility genes need further investigation. The purpose of this review is to present current literature evidence regarding genes responsible for DDH development. Cite this article: EFORT Open Rev 2019;4:595-601.

Clinical Overview

Introduction The most common musculoskeletal evaluation in the neonatal period and infancy is assessing the child's hips. Treatment of hip dislocation is most successful when begun early, making it imperative that all children undergo repeated, careful hip examinations beginning in infancy until walking age. Those physicians entrusted with the initial examination should have a clear understanding of the etiology, prevalence, and presentation of developmental dysplasia of the hip as well as the appropriate physical examination for this entity. Historically, the term "congenital dislocation/dysplasia of the hip" (CDH) has been used. Reports illustrating cases of late diagnosis of hip abnormalities in patients who previously have had normal clinical and/or radiographic examinations as well as recognition of the wide spectrum of abnormalities from dislocation to dysplasia have led the orthopedic and pediatric communities to adopt the term developmental dislocation/dysplasia of the hip (DDH). This term now is preferred. Definitions and Categorization Hip dislocation can be categorized as "typical" or "teratologic." Teratologic dislocations are uncommon and usually are associated with neuromuscular abnormality, arthrogryposis, or myelomeningocele and typically are high, fixed dislocations. In contrast, "typical" DDH occurs in neurologically normal infants and encompasses a wide spectrum of deformity and presentation. It is important to recognize that previously stable hips may become unstable during infancy, and repeated examinations are needed until the child is of walking age.

INTRODUCTION The objective of this study was to assess if there is a significant learning curve in the treatment of developmental dysplasia of the hip. PATIENTS AND METHODS We followed up cases of developmental dysplasia of the hip treated by a single surgeon over a 12-year period. There were 96 cases, 56 treated by open reduction and 40 treated by closed reduction. Assessment was made of the incidence and degree of avascular necrosis in the treated hips, as a radiological outcome measure. RESULTS Plotting the cumulative percentage of satisfactory outcomes demonstrated an increasingly high percentage of satisfactory results with increasing number of procedures performed, i.e. as the surgeon progressed up the ‘learning curve’. CONCLUSIONS This study demonstrates a learning curve in the treatment of developmental dysplasia of the hip. It may be possible to draw parallels to other treatments, and also support for the growing trend to specialisation.
