Background: Deficits in upper body movement have received little attention during gait in cerebral palsy (CP) children with crouch gait pattern (CGP).Objective: Purpose of this research is to describe the correlation of trunk movement with the excessive knee flexion and ankle kinematic in CP children with CGP.Methods: Gait analysis data from 57 limbs of diplegic CP children with CGP and 26 limb...

normal axial alignment restoration in lower extremities is crucial for surgeons performing reconstructive surgeries. since reference normal values of axial alignment are affected by age, sex, and ethical issues, we tried to scrutinize these parameters in iranian adults and compare them with normal values in literatures. through a cross-sectional design, standing axial alignment views of lower e...

Introduction: Acetabular dysplasia is common in our country. The experience with periacetabular “Ganz” osteotomy is relatively low. We would like to report our short‐term experience in a small group of patients who received such a surgery. Materials and Methods: In a descriptive study, 15 patients with dysplastic acetabula who had undergone “Ganz” pelvic osteotomy were evaluated for their clini...

Leg-length inequality is an extensively studied complication of total hip arthroplasty in normal patients. However, few studies have focused on the pelvic obliquity of coronal pelvic malrotation. We hypothesized that pelvic obliquity with a fixed abduction/adduction contracture deformity of the hip may intraoperatively affect the release of soft tissues, ultimately resulting in a leg-length ine...

OBJECTIVE While several radiographic parameters have been established to describe the geometry and pathology of the hip, their reference values and clinical significance remain a matter of dispute. The present study tests the hypothesis that age has a relevant impact on radiographic hip parameters. METHOD Pelvic antero-posterior views were measured for CE angle, Sharp's angle, acetabular dept...

The oblique magnetic rotator is a satisfactory model describing the general properties of the magnetic Ap stars. The inferred rotation periods are almost always considerably longer than those of the normal A stars. The loss of angular momentum is plausibly the result of magnetic coupling with external gas during some epoch in the star’s life. The same Maxwell stresses that brake the stellar rot...

Finite element method is employed to analyze the spherical vessel intersected by an oblique cylindrical nozzle. In this survey the stress and strain distributions on acute and obtuse sides of the connection under internal pressure are studied widely although axial and moment loadings on the nozzle are also studied briefly. Stress concentration factors for a wide range of geometrical ratios in t...
