BACKGROUND: Relationships between low back pain (LBP) and the hip in patient cohorts have been described primarily in patients with moderate to severe hip osteoarthritis (OA). Less is known about the links of LBP with hip radiographic findings of hip deformity and minimal OA. OBJECTIVE: The objectives were to 1) describe the incidence of radiographic hip deformity or hip OA, 2) describe and compare spine and hip related pain and function in the subset of patients who were found to have radiographic hip deformity or hip OA, and (3) compare patients with evidence of radiographic hip deformity or hip OA to patients without hip radiographic findings...

REVIEW
Robin W Paton
Screening for Developmental Dysplasia of the Hip (DDH) is a controversial subject. Screening may be by universal neonatal clinical examination (Ortolani or Barlow manoeuvres) with the addition of sonographic imaging of the hip (selective 'at risk' hips or universal screening in the neonate). In the UK, the NIPE guidelines recommend universal neonatal clinical assessment of the hip joints, a General Practitioner 6-8 week clinical 'hip check' and assessment clinically with sonographic imaging at 4-6 weeks for certain 'at risk' hips for pathological DDH...

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the most common congenital defects in the newborn. When its severe form is not corrected, it is associated with long-term morbidity. Closed reduction with casting is the standard primary treatment and reduction is confirmed by magnetic resonance imaging (MRI). We reported our experience on the reliability of MRI in postreduction assessment of DDH. METHODS: All children who underwent closed reduction for Graf type IV DDH at our institution between September 2010 and June 2016 were retrospectively reviewed...

A bacterial strain, TH1-2(T), was isolated from cyanobacterial aggregates in the eutrophic Lake Taihu, Jiangsu Province, China. Cells were observed to be Gram-negative, slightly curved and rod-shaped. Optimal growth was obtained at pH 7.0 (range 5.5-8.5) and 30 °C (range 20-37 °C) in trypticase soy broth (TSB) without NaCl. Growth was not observed in TSB with 1.0% (w/v) NaCl added. The cells were found to be positive for oxidase and catalase activities. The major fatty acids were identified as 3-hydroxy hexadecanoic acid (C16:0 3-OH), C16:1 ω5c and summed feature 8 (consisting of C18:1 ω6c and cis-11-Octadecenoic acid (C18:1 ω7c)...

Developmental dislocation of the hip(DDH) is one of the most serious hip diseases. Patients with unilateral DDH are prone to secondary osteoarthritis, low back pain, gait disturbance and compensatory scoliosis because of the leg length discrepancy. Total hip arthroplasty(THA) is the highly effective treatment for patients with hip pain or dysfunction caused by unilateral DDH, thus decrease the demand for hip-preserving surgeries such as capsular arthroplasty which may postpone or avoid hip replacement. However, the failure rate of THA for young patients is high and the majority of young patients may require one or more revision arthroplasties throughout their lifetime...

BACKGROUND: Developmental dysplasia of the hip (DDH) occurs in 3-5 of 1000 live births and is associated with known risk factors. In most countries, formal practice for early detection of DDH entails the combination of risk factor identification and physical examination of the hip, while the golden standard diagnostic instrument is hip ultrasonography (US). This practice is commonly referred to as selective screening. Infants with positive US findings are treated with a Pavlik harness, a dynamic abduction splint...

BACKGROUND: A high rate of postoperative dislocation in total hip arthroplasty (THA) for Crowe IV developmental dysplasia of the hip (DDH) has been reported, 1 of the main reasons being higher true acetabular anteversion. If the cup is fixed with normal anteversion, the anterior rim will be excessively exposed, which reduces the contact areas of the cup and bone, affects prosthesis stability, and leads to iliopsoas tendinitis and persistent hip pain after THA. The aim of this study was to demonstrate that when cup anteversion is larger, adjusting femoral anteversion to bring the combined anteversion (CA) into the "safe zone" might prevent dislocation...

Developmental dysplasia of the hip (DDH) is a complex disorder of the hip joint affecting 1-5‰ of newborns. While genetic influence on DDH has been long known, DDH has not been ascribed to any specific genetic event. The present study reported on variants contributing to DDH susceptibility in a family with four individuals affected across three generations. Whole-exome sequencing was performed in three affected and two unaffected individuals of a pedigree with DDH. Candidate variants were confirmed by Sanger sequencing and then validated in available family members and 37 sporadic DDH patients...

Introduction: Hip spica casting is an important component of treatment for developmental dysplasia of the hip (DDH) and popular treatment method for femur fractures in children. Breakage at the hip region is a relatively common problem of this cast. We have developed a three-slab technique of hip spica application using fibreglass as the cast material. The purpose of this review was to evaluate the physical durability of the spica cast and skin complications with its use. Methodology: A retrospective review of children with various conditions requiring hip spica immobilisation which was applied using our method...

Developmental dysplasia of the hip (DDH) is a relatively common malady that has profound consequences in the infant if left untreated. Effective and early treatment of DDH has been praised as one of the most successful ventures of modern pediatric orthopedics. Yet, before the modern management of DDH came into existence, there were extensive technological developments in the field of harnesses, casts, and traction methods. This paper aims to identify the centuries-old history of advancement in DDH treatment and the many important people involved...

BACKGROUND: The prevalence of developmental dysplasia of the hip (DDH) is unknown in China. We aimed to determine the prevalence of DDH in Chinese adults. METHODS: In this study, we performed a cross-sectional survey of a nationally representative sample of Chinese adults. All participants underwent questionnaire investigation, physical examination, and X-ray examination. Factors associated with DDH were analyzed with logistic regression. RESULTS: We invited 29,180 individuals aged 18 years and over to participate, randomly selected from 18 primary sampling units (street districts in urban areas and townships in rural areas)...

BACKGROUND: Developmental hip dysplasia (DDH) may lead to severe acetabular and femoral abnormalities that can render total hip arthroplasty (THA) challenging, especially in DDH patients with a small physique. Most conventional cemented or cementless femoral components are often difficult to implant in the narrow femoral canal and require slight version correction during surgery. The aim of this study was to present the mid-term results of THA in the treatment of DDH patients with a small physique using a cementless Wagner cone prosthesis (Zimmer®, US)...

Developmental dysplasia of the hip (DDH) is the commonest 'congenital' disease of the locomotor system throughout the world. According to the World Health Organisation (WHO) Bone & Joint Decade (2000-2010) 10%-15% of patients who are under the age of 50 when they require a hip replacement do so because of infant hip dysplasia.The background; technique and common mistakes; results; debate and politics; and the challenges of infant hip sonography are reviewed.

INTRODUCTION: Developmental dysplasia of the hip (DDH) refers to the spectrum of abnormalities of maturation and development of the hip. Breech presentation is associated with DDH. This risk factor can be modified by external cephalic version (ECV). The aim of this study is to evaluate the incidence of DDH in patients who successfully underwent ECV, as well as to evaluate need for these children (breech for a period during gestation) to be included in the DDH screening protocol. MATERIAL AND METHODS: A prospective cohort study was conducted in the Hospital Universitario de Vigo from January 1, 2015 to December 31, 2015...

Developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) are separate causes of premature osteoarthritis. There is a paucity of literature describing potential ways in which an individual can be predisposed to FAI. This hypothesis aims to outline how subclinical DDH may predispose a patient to FAI. In DDH the acetabular malformation of the hip joint alters the weight distribution superiorly in the loading axis. In accordance with Wolff's Law, we propose that this change in loading may result in the formation of protrusions on either the acetabular rim or femoral head and neck, predisposing to impingement of the hip during to certain movements and consequently, FAI...

BACKGROUND: Concern for increased risk of osteonecrosis in hips with an absent ossific nucleus has led some surgeons to delay reduction in the treatment of developmental dysplasia of the hip (DDH) until the ossific nucleus is present. A previous meta-analysis reported a potential protective effect against high-grade osteonecrosis (II to IV) when the ossific nucleus was present. With a greater number of publications on this topic, revisiting this analysis is warranted. The aim of this meta-analysis was to systematically review and analyze the best clinical evidence regarding the association between the status of the ossific nucleus and development of osteonecrosis following the treatment of DDH...

BACKGROUND: Total hip arthroplasty (THA) through the direct anterior approach (DAA) is known to cause less muscle damage than other surgical approaches. However, more complex primary cases, such as developmental dysplasia of the hip (DDH), might often cause muscle damage. The objective of the present study was to clarify the muscle damage observed 1 year after THA through the DAA for DDH using magnetic resonance imaging. METHODS: We prospectively compared the muscle cross-sectional area (M-CSA) and fatty atrophy (FA) in muscles by magnetic resonance imaging and the Harris hip score before and at 1-year follow-up after THA through the DAA in 3 groups: 37 patients with Crowe group 1 DDH (D1), 13 patients with Crowe group 2 and 3 DDH (D2 + 3), and 12 patients with osteonecrosis as a control...

BACKGROUND: A meta-analysis concluded that there was no effect of the femoral head ossification and the incidence of osteonecrosis in the treatment of developmental dysplasia of the hip (DDH), unless only osteonecrosis grades II-IV were considered. The meta-analysis, limited due to the small number of studies available at that time, identified a need for an update as further research emerges. We observed a trend in recent years towards delaying treatment of DDH in the absence of an ossified nucleus...
