: This study utilized a computational biomechanical model and applied the least energy path principle to investigate two pathways for closed reduction of high grade infantile hip dislocation. The principle of least energy when applied to moving the femoral head from an initial to a final position considers all possible paths that connect them and identifies the path of least resistance. Clinical reports of severe hip dysplasia have concluded that reduction of the femoral head into the acetabulum may occur by a direct pathway over the posterior rim of the acetabulum when using the Pavlik harness, or by an indirect pathway with reduction through the acetabular notch when using the modified Hoffman-Daimler method...

National Health Service Quality Improvement Scotland (NHS QIS) published a health technology scoping report in 2006 acknowledging that there are serious concerns within Scotland in relation to Developmental Dysplasia of Hip (DDH) as there is no formal screening program in place and there are significant variations between NHS boards leading to confusion for staff and parents. NHS QIS identified need for audit work to improve hip screening in Scotland. The aim of this study is review of current practice of selective screening for DDH...

BACKGROUND: We asked whether patient-specific factors and ultrasound (US) measurements of hip dysplasia severity at initial examination influence short-term residual acetabular dysplasia in patients successfully treated with Pavlik harness for developmental hip dysplasia. METHODS: After IRB approval, 134 hips (84 patients) successfully treated by the Pavlik method between August 2011 and October 2014 with follow-up at 12 months of age were identified. Early successful treatment was defined as normal examination and US after approximately 12 weeks of Pavlik treatment...

BACKGROUND: The Pavlik harness is the most common initial treatment for developmental dysplasia of the hip worldwide. During treatment, parents are required to re-apply the harness at home. Teaching parents how to apply the harness is therefore paramount to success. While simulated learning for medical training is commonplace, it has not yet been trialed in teaching parents how to apply a Pavlik harness. METHODS: A group of parents underwent a simulated learning module for Pavlik harness application...

BACKGROUND: Simulation-based learning is increasingly prevalent in many surgical training programs, as medical education moves toward competency-based curricula. In orthopaedic surgery, developmental dysplasia of the hip is a commonly treated condition, where the standard of care for patients less than six months of age is an orthotic device such as the Pavlik harness. However, despite widespread use of the Pavlik harness and the potential complications that may arise from inappropriate application, we know of no previously described formal training curriculum for Pavlik harness application...

PURPOSE: The purpose of this study was to identify and evaluate risk factors of avascular necrosis (AVN) after closed treatment for developmental dysplasia of the hip (DDH). METHODS: A retrospective review of children diagnosed with DDH at a tertiary-care children's hospital between 1986 and 2009 was performed. The presence of AVN was assessed according to Salter's classification system. RESULTS: Eighty-two affected hips in 70 children with an average age of 10 months at closed reduction (range 1-31 months) and 5 years (range 2-19 years) of follow-up met the inclusion criteria...

We used a three-dimensional rigid body spring model (RBSM) to compare the contact force distributions on the acetabular surface of the infant hip joint that are produced by three orthopedic treatments for developmental dysplasia of the hip (DDH). We analyzed treatments using a Pavlik harness, a generic rigid splint, and a spica cast. The joint geometry was modeled from tomography images of a 1-year-old female. The articular cartilage was modeled as linear springs connecting the surfaces of the acetabulum and the femoral head, whereas the femur and the hip bone were considered as rigid bodies...

Developmental dysplasia of the hip (DDH) requires precise evaluation and rapid treatment/referral to specialists to optimize results. The incidence of DDH ranges between 4/1,000 and 133/1,000 newborns depending on patient risk factors (female gender, breech birth, and family history). Multiple associations have been identified including metatarsus adductus, oligohydramnios, and muscular torticollis. Classic physical examination results are well known by pediatricians, but can be difficult to elicit. Ultrasound screening is a useful test in defining early dysplasia and dislocation, but can generate misleading results if used inappropriately...

Developmental dysplasia of the hip is a spectrum disorder of hip development that ranges in severity from abnormal acetabular morphology to complete hip dislocation. While treatment with a Pavlik harness is highly effective in infants younger than 6 months, older infants and children and those with orthotic failure often warrant surgical reduction and placement of a spica cast, which limits subsequent imaging evaluation. Magnetic resonance (MR) imaging has been described in the evaluation of the adequacy of hip reduction for more than 2 decades, but the practice is still not widespread and is performed routinely at relatively few centers...

BACKGROUND: Patients with developmental dysplasia of the hip (DDH) whose hips are dislocated but reducible (Ortolani positive) are more likely to experience Pavlik harness treatment failure than are patients with dysplastic and reduced but dislocatable (Barlow positive) hips. However, data regarding factors associated with failure are limited and conflicting. QUESTIONS/PURPOSES: We asked: (1) What is the frequency of Pavlik harness treatment failure among Ortolani-positive hips, Barlow-positive hips, and dysplastic hips? (2) What are the factors predictive of failure of Pavlik harness treatment for Ortolani-positive hips? METHODS: In this retrospective study we identified 150 patients who underwent the Pavlik harness method for treatment of DDH between August 2011 and July 2015...

Developmental dysplasia of the hip (DDH) describes the spectrum of structural abnormalities that involve the growing hip. Early diagnosis and treatment is critical to provide the best possible functional outcome. Persistence of hip dysplasia into adolescence and adulthood may result in abnormal gait, decreased strength and increased rate of degenerative hip and knee joint disease. Despite efforts to recognize and treat all cases of DDH soon after birth, diagnosis is delayed in some children, and outcomes deteriorate with increasing delay of presentation...

INTRODUCTION: Because of the risk of developmental dysplasia of the hip in infants born breech-despite a normal physical exam-the American Academy of Pediatrics (AAP) guidelines recommend ultrasound (US) hip imaging at 6 weeks of age for breech females and optional imaging for breech males. The purpose of this study is to report US results and follow-up of infants born breech with a normal physical exam. METHODS: The electronic medical record for children born at 1 hospital from 2008 to 2011 was reviewed...

BACKGROUND: Up to 4% of all neonates in Central Europe are born with congenital hip dysplasia (CHD), the most common congenital disease of the musculoskeletal system. However, in this retrospective analysis the outcomes of infants with CHD (type D, III or IV according to Graf) have been considered, with Pavlik therapy starting within the first 12 weeks of life. Connections between the start of therapy or the first finding according to Graf`s classification and the ultrasound result achieved, as well as the X-rays taken after 1 and 2 years, were evaluated...

BACKGROUND: Management of developmental dysplasia of the hip (DDH) with a Pavlik harness is a well-known treatment.Follow-up until skeletal maturity is recommended as long-term studies mention late sequelae.The purpose of this study was to determine whether such a follow-up is necessary in patients treated successfully under a strict protocol. METHODS: A retrospective review of a consecutive series of normal infants treated for DDH between January 1995 and July 2004 was undertaken...

BACKGROUND: Osteogenesis imperfecta (OI) is a heritable skeletal disorder characterized by bone fragility and short stature that is usually due to mutations in 1 of the 2 genes that code for collagen type I α-chains. The association between hip dysplasia and OI has not been systematically investigated. In this single-center study, we retrospectively reviewed all cases of OI associated with hip dysplasia to describe clinical characteristics and the effect of therapy. METHODS: We reviewed the charts of 687 patients with OI who were seen at the Shriners Hospital for Children in Montreal between 1999 and 2013 to identify patients with a diagnosis of hip dysplasia...

This study was performed to determine whether overgrowth occurs when treating infantile femoral shaft fractures with a Pavlik harness. Twenty-three patients, aged less than 1 year, treated with a Pavlik harness for a femoral shaft fracture were included. Shortening at the time of injury was recorded on radiographs and compared with those obtained at the follow-up visit 18 months or later. Average overgrowth was 5 mm (1-18 mm). Overgrowth occurs in infants following treatment of femoral fractures with a Pavlik harness...

The best screening method for developmental dysplasia of the hip is controversial. Ultrasonography is sensitive, but cost-effectiveness may limit its use. This study assessed whether ultrasound screening would increase in effectiveness if targeted toward infants with established risk factors for developmental dysplasia of the hip and normal findings on physical examination. All ultrasound scans performed at the authors' institution from January 2007 through January 2011 to screen for developmental dysplasia of the hip were reviewed...
