We used three-dimensional (3D) MRI to assess the sphericity of the cartilaginous femoral head in developmental dysplasia of the hip. We assessed 21 children using 3D-MRI. The smallest sphere including the femoral head cartilage was drawn, the diameter was measured, and the center of the sphere was defined. We compared the diameters of the femoral heads between unaffected and diseased sides. The diameter of the affected side was smaller, with flattening at the posteromedial area and proximoposterior areas. 3D-MRI showed that the shape of the dislocated femoral head was aspherical with focal growth failure...

PURPOSE: Excessive in-spica abduction is a risk factor for oste-onecrosis after surgical reduction for developmental dysplasia of the hip (DDH). The traditional method for radiographically measuring hip abduction using axial imaging does not reflect the true angle, which usually lies in an oblique plane. The purpose of this study was to describe a novel method for measuring true hip position using advanced imaging. METHODS: A trigonometric model was derived to define hip position based upon the femoral axis angular deviation from midline as measured on axial and coronal sequences of MRI studies...

BACKGROUND: The purpose of this study was to investigate the 3-dimensional (3D) morphological features of the true acetabulum in patients with developmental dysplasia of the hip (DDH). METHODS: Seventy-nine hips-53 in patients with developmental dysplasia of the hip (DDH) and 36 normal hips-were included in the present study. According to the Crowe classification, 26 hips were graded as Class I, 31 were Class II or III, and 22 were Class IV. The anterior pelvic plane was defined to standardize the measurements in the study...

AIM: There is no evidence on the effect of universal ultrasound screening on developmental dysplasia of the hip. We examined the impact of adding an ultrasound examination to a one examiner clinical screening strategy on treatment, follow-up rates and the number of cases detected late in a low-prevalence population. METHODS: All eligible babies born at Kongsberg Hospital, Norway, from 1998-2006 (n=4,245) underwent both clinical and ultrasound hip examinations within three days of life...

Developmental dysplasia of the hip (DDH) is a congenital or developmental deformation or misalignment of the hip joint that is affected by environmental and genetic factors. Recently, polymorphisms in both TGFB1 and IL-6 have been identified as being significantly associated with hip osteoarthritis in Caucasians. In this study, we conducted a case-control study involving 4,206 Han Chinese individuals to investigate the effects of TGFB1 and IL-6 on the disease status and severity of DDH. A total of 32 single-nucleotide polymorphisms (SNPs) were selected to ensure coverage of the two genetic loci...

Several reports have shown good long-term results with the Birmingham hip resurfacing (BHR) arthroplasty, but little is known about the results in Asian countries where there is a high prevalence of osteonecrosis and developmental dysplasia of the hip, and many females with small femoral head sizes. Therefore, we retrospectively evaluated the long-term clinical results of the BHR in 112 Japanese patients (53 males and 59 females-130 hips) with an average age of 52 years. Implant survivorship was analyzed using the Kaplan-Meier method with the endpoint being revision for any reason...

PURPOSE: Developmental dysplasia of the hip (DDH) presents a considerable surgical challenge in total hip arthroplasty (THA). Although the usefulness of computed tomography (CT)-based navigation in cup alignment has been reported, few reports have evaluated three-dimensional (3-D) cup positioning against the acetabulum specifically in patients with DDH. The purpose of this study was to evaluate the efficacy of a CT-based navigation system for alignment and spatial positioning of the cup in THA for patients with DDH...

BACKGROUND: Redislocation is a dreaded complication after reduction of developmental dysplasia of the hip (DDH) in young children. While early detection facilitates urgent reoperation, delayed revisions are more complicated. Despite the weak evidence, an axial postoperative imaging tool is recommended. This study's goal is to compare the effectiveness of conventional pelvic radiography alone and axial imaging. METHODS: Data were collected retrospectively between 2012 and 2016...

Background and Aims Developmental dysplasia of the hip is a common cause of osteoarthritis. Periacetabular osteotomy can restore femoral head coverage; however, it is reserved for patients with minimal articular degeneration. We examined the relationship between delays in diagnosis and outcomes. Methods We identified patients presenting to a hip specialist with a new diagnosis of hip dysplasia. The time taken between patients presenting to their general practitioner and attending the young adult hip clinic was established...

PURPOSE: Early detection and intervention for developmental dysplasia of the hip (DDH) is important for normal hip development. Previous studies have shown disparities in access to paediatric specialty care among different racial and socioeconomic backgrounds. This study aims to identify whether these factors are related to timely referral for infants with DDH. METHODS: A retrospective cohort study of patients seen and treated for DDH between July 2006 and June 2011 at a single institution were reviewed...

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, shortening, abnormal gait, and pain. Many authors have suggested proximal femoral valgus osteotomy for the treatment of unstable hip joints. Ilizarov modified this technique and performed a double-level osteotomy. In addition to proximal femoral valgus extension osteotomy, he introduced a distal femoral varus osteotomy which would lead to limb lengthening and correction of mechanical axis of the leg...

BACKGROUND: Flare-ups of the hips are among the most feared and disabling complications of fibrodysplasia ossificans progressiva (FOP) and are poorly understood. In order to better understand the nature of hip flare-ups in FOP, we evaluated 25 consecutive individuals with classic FOP (14 males, 11 females; 3-56years old, median age, 17years old) who presented with acute unilateral hip pain. RESULTS: All 25 individuals were suspected of having a flare-up of the hip based on clinical history and a favorable response to a four day course of high-dose oral prednisone...

Biomechanics of the hip joint describes how the complex combination of osseous, ligamentous, and muscular structures transfers the weight of the body from the axial skeleton into the appendicular skeleton of the lower limbs. Throughout history, several biomechanical studies based on theoretical mathematics, in vitro, in vivo as well as in silico models have been successfully performed. The insights gained from these studies have improved our understanding of the development of mechanical hip pathologies such as osteoarthritis, hip fractures, and developmental dysplasia of the hip...
