We investigated the variables which determine the outcome after triple osteotomy of the pelvis for the treatment of congenital dysplasia of the hip. We reviewed 51 patients (61 hips) with a median age at operation of 23 years who were treated with a Tönnis triple osteotomy. The median follow-up was six years with a minimum of two years. Eight patients (eight hips) required a revision procedure....

Abstract Background Finite element analysis (FEA) has been previously applied for the biomechanical of acetabular dysplasia and osteotomy. However, until now, there have little reports on use FEA to evaluate effects pelvic tilt stress distribution in acetabulum. Methods We used Mechanical Finder Ver. 7.0 (RCCM, Inc., Japan) construct finite models based 3D-CT data patients, designed dysplasia, ...

OBJECTIVES To investigate whether adult patients with unilateral developmental dysplasia of the hip (UDDH) have pelvic asymmetry and what correlation existing between them. Methods: A total of 100 adult patients with UDDH were enrolled in the retrospective observational study in Shanghai Jiaotong University Affiliated Sixth People's Hospital, Shanghai, China, between January 2012 and February 2...

BACKGROUND Hip instability has classically been associated with developmental dysplasia of the hip (DDH) in newborns and children. However, numerous factors may contribute to hip instability in children, adolescents, and adults. PURPOSE This review aims to concisely present the literature on hip instability in patients of all ages in order to guide health care professionals in the appropriate...

We investigated effectiveness and potential use of early diagnosis of hip joint dysplasia in German Shepherd dogs by X-ray examination comparing the conventional extension position I with compression-distraction method. In addition to that we also used Ortolani palpation technique and X-ray examination of the hip joint in order to obtain view of its dorsal acetabular rim (DAR) and dorsal acetab...

The purpose of this study was to describe the physical activity level of adolescents with cerebral palsy (CP) and to investigate the associated factors. The physical activity level was measured by means of a questionnaire filled in by the parents of 72 adolescents with CP (12-16 years of age) and expressed in METs. Older age, female gender, and hip dysplasia were significantly associated with a...

Most osteoarthritis of the hip is associated with chronic abnormal hip mechanics,1 related to potentially treatable anatomic abnormalities.2 The rationale of mechanically-based measures to prevent or treat osteoarthrosis assumes the following: (a) the correctable mechanical abnormality is a major etiologic factor in osteoarthrosis; (b) relief of the mechanical abnormality can prevent or improve...

Introduction
 Developmental dysplasia of the hip (DDH) includes femoral head subluxation or dislocation and/or acetabular dysplasia. The gold standard treatment for DDH during walking age remains controversial. Treatment modalities that have been proposed to treat after are osteotomy and pelvic osteotomy. aim this study was assess radiographic results surgical age.

INTRODUCTION Developmental hip dysplasia represents the most common deformation of locomotor system in children. Developmental modulation of the hip is expressed during first year of life which is important for early diagnosis and treatment. Therefore, in the practice, it is very important to set a diagnosis early with application of simple and convenient methods (ultrasound) in order to achiev...

Abnormal hip development causes one-quarter to one-half of all hip disease. Dysplastic hips typically share characteristic anatomic abnormalities. The dysplastic acetabulum is typically shallow, lateralized, and anteverted with insufficient coverage anteriorly, superiorly, and laterally. The dysplastic proximal femur has a small femoral head with excessive femoral neck anteversion and a short n...
