BACKGROUND: The Pavlik harness has been used for approximately a century to treat developmental dysplasia of the hip (DDH). Femoral nerve palsy is a documented complication of Pavlik harness use, with an incidence ranging from 2.5% to 11.2%. Rare reports of brachial plexus palsy have also been documented. The primary purpose of the current study was to evaluate the incidence of various nerve palsies in patients undergoing Pavlik harness treatment for DDH. Secondary aims were to identify patient demographic or hip characteristics associated with nerve palsy...

PURPOSE OF THE STUDY Different techniques have been reported to reconstruct the defi cient acetabulum during total hip arthroplasty (THA). The purpose of this study was to compare the biomechanical features of the bulk bone graft (BBG) technique (Harris acetabular plasty) and the Roof Step Cut (RSC) technique using fi nite element analysis. MATERIAL AND METHODS Based on a female patient's dysplastic hip CT scan, 3D models were assembled according to the two techniques. For the Harris technique, an irregular BBG was sculpted from a solid sphere, while for the RSC technique, the graft was sculpted into a step-cut shape with a similar size...

High body weight (BW), due to large size or excess body fat, has been associated with developmental and metabolic alterations, and degenerative diseases in dogs. Study objectives were to determine mean BW in young adult dogs of different breeds, including changes over a 10-year period. Body weight data from the official Swedish hip dysplasia screening program were used, including data from dogs screened at 1-2.5 years of age, in breeds with ≥ 15 individual observations/year during 2007-2016...

BACKGROUND: Developmental dysplasia of the hip (DDH) is a condition associated with hip pain and impairments. Periacetabular osteotomy (PAO) is a common surgical treatment for DDH. Outcomes following PAO have historically been based on radiology or patient reported outcomes, and not physical impairments. OBJECTIVE: To investigate differences in physical impairments in adults with DDH undergoing PAO compared with asymptomatic participants, and to investigate pre- to post-PAO changes in physical impairments...

PURPOSE OF THE STUDY Cementless stems in highly dysplastic hips are considered to increase the risk of femoral fracture and associated morbidity. Several authors speculated to use prophylactic cabling in this patient group to prevent intraoperative fractures. This study aims to reveal objective results regarding the perioperative complications in a large and consecutive patient group with respect to use of prophylactic cabling. MATERIAL AND METHODS A retrospective comparative study was planned. A total of 122 consecutive patients with dysplastic hips of Crowe type 3 or 4, operated on with total hip arthroplasty (THA) and shortening osteotomy using a rectangular femoral stem were included...

OBJECTIVE: To study the protective effect and mechanism of rutin on perfluorooctanoic acid(PFOA)-induced liver damage in mice. METHODS: A total of 24 male ICR mice were randomly divided into 3 groups, 8 in each group: control group(ctrl group: ddH_2O), perfluorooctanoic acid group(PFOA group: PFOA 20 mg/(kg·d)), rutin intervention group(rutin+PFOA group: PFOA 20 mg/(kg·d)+rutin 20 mg/(kg·d)), normal diet, oral gavage, daily observation, weighting, and recording...

In an ongoing Microbial Observatory investigation of the International Space Station (ISS), 11 Bacillus strains (2 from the Kibo Japanese experimental module, 4 from the U.S. segment, and 5 from the Russian module) were isolated and their whole genomes were sequenced. A comparative analysis of the 16S rRNA gene sequences of these isolates showed the highest similarity (>99%) to the Bacillus anthracis-B. cereus-B. thuringiensis group. The fatty acid composition, polar lipid profile, peptidoglycan type, and matrix-assisted laser desorption ionization-time of flight profiles were consistent with the B...

PURPOSE: Developmental dysplasia of the hip (DDH) is a congenital deformity which in severe cases leads to hip dislocation and in milder cases to premature osteoarthritis. Image-aided diagnosis of DDH is partly based on Graf classification which quantifies the acetabular shape seen at two-dimensional ultrasound (2DUS), which leads to high inter-scan variance. 3D ultrasound (3DUS) is a promising alternative for more reliable DDH diagnosis. However, manual quantification of acetabular shape from 3DUS is cumbersome...

The incidence of clinically significant avascular necrosis (AVN) following medial open reduction of the dislocated hip in children with developmental dysplasia of the hip (DDH) remains unknown. We performed a systematic review of the literature to identify all clinical studies reporting the results of medial open reduction surgery. A total of 14 papers reporting 734 hips met the inclusion criteria. The mean follow-up was 10.9 years (2 to 28). The rate of clinically significant AVN (types 2 to 4) was 20% (149/734)...

INTRODUCTION: Developmental dysplasia of the hip (DDH) can result in chronic pain, gait abnormalities and degenerative arthritis. Infants with a family history, Breech delivery or unstable/"clicking" of the hip on examination are at higher risk. The goal is to detect cases early enough for normal hip development and function by the end of adolescence, but clinical examination alone is ineffective. MATERIALS AND METHODS: All infants born at the West Middlesex University Hospital, Isle-worth, U...

PURPOSE OF THE STUDY: Developmental dysplasia of the hip (DDH) is a serious anatomical abnormality. The aims of the study were to compare the current views on general screening for DDH and, in a group of patients diagnosed for DDH both clinically and ultrasonographically, to analyse the results of their treatment with Wagner stockings. MATERIAL AND METHODS: In the years 2000 to 2001, a total of 3,221 children were examined at birth clinically and by ultrasonography using Graf's method...

OBJECTIVE: To document the quality of life of children who have been treated for developmental dysplasia of the hip (DDH) within the first 3 years of life successfully after a minimum follow-up period of 2 years, and compare their results with healthy age-matched children. METHODS: Thirty patients with DDH treated between 1998 and 2002 in Ankara Numune Education and Research Hospital, Ankara, Turkey and 19 age-matched healthy controls were included in this study with the approval of the ethical committee...

A colorimetric DNA-DNA hybridization for the genetic identification of mycobacteria, DDH MYCOBACTERIA 'KYOKUTO' (Kyokuto Pharmaceuticals, Tokyo) was evaluated for the clinical isolates of mycobacteria grown in Middlebrook 7H9 broth of MB/BacT (Organon Teknika, Durham, NC, U.S.A.). When the MB/BacT gave the positive interpretation, 10 ml of Middlebrook 7H9 broth was collected from the bottle. After centrifugation at 3,000 rpm for 10 min, two drops of acetone were added to the pellet, then let it stand for one hour at the room temperature...

AIM OF STUDY: To assess the effectiveness of a universal sonographic screening of developmental dysplasia of the hip (DDH) established in Germany since 1996. METHODS: Currently a national survey is being performed in Germany to identify infants and young children who receive inpatient treatment for DDH. Between May, 1997 and October, 1997 monthly questionnaires were sent to all pediatric orthopaedic surgeons (active surveillance) and they were asked to report all inpatient cases between 10 weeks of age and 5 years with current closed or open reduction and/or osteotomies due to DDH...
