To investigate kinetic differences in the coronal plane between healthy individuals wearing shoes with lateral-offset soles and shoes with lateral-wedge insoles while walking, hip abduction, knee adduction, and ankle abduction moments were estimated using a 3-dimensional motion analysis system under 3 different conditions: wearing conventional shoes (control), wearing lateral-offset sole shoes ...

INTRODUCTION Legg-Calvé-Perthes Disease (LCPD) represents idiopathic avascular necrosis of femoral head in pediatric population. Indications for treatment depend mostly on prognosis about femoral head sphericity and hip congruence at the end of growth. The aim of this review is to highline prognostic factors of LCPD. METHODS Bibliographic search in PubMed allowed selection of 33 articles conc...

Aim: To explore an accurate method to calculate acetabular cup anteversion after total hip arthroplasty. Method: 1) A 3D coordinate system was established with the center of the hip joint rotation center base as coordinate center. The acetabular exit plane and Pettersson formula acetabular anteversion and Riten Pradhan formula acetabular anteversion and acetabular true anteversion were drawn; 2...

Developmental dysplasia of the hip refers to a continuum of abnormalities in the immature hip that can range from subtle dysplasia to dislocation. The identification of risk factors, including breech presentation and family history, should heighten a physician's suspicion of developmental dysplasia of the hip. Diagnosis is made by physical examination. Palpable hip instability, unequal leg leng...

BACKGROUND Acetabular component orientation influences joint stability in total hip arthroplasty (THA). The purpose of this study was to evaluate the effect of cup orientation and other variables on hip dislocation risk and to define a posterior approach specific safe zone. METHODS A cohort of 1289 posterior approach primary THA cases was prospectively followed and component position measured...

Abstract Background Leg length (LL) and offset (OS) are important factors in total hip arthroplasty (THA). Because most LL OS callipers used THA depend on fixed points the pelvis femur, limb position could affect measurement error. This study was conducted a simulator to clarify effects of lower iliac pin errors determine permissible range for accurate measurement. Methods An instrument used. T...

OBJECTIVE To compare differences in hip and knee kinematics and kinetics in male and female recreational runners. DESIGN Gait analysis of 20 men and 20 women recreational runners. BACKGROUND Female runners are reported to be more likely to sustain certain lower extremity injuries compared to their male counterparts. This has been attributed, in part, to differences in their structure and it...

STUDY DESIGN Cross-sectional. OBJECTIVES To investigate whether females seeking physical therapy treatment for unilateral patellofemoral pain syndrome (PFPS) exhibit deficiencies in hip strength compared to a control group. BACKGROUND Decreased hip strength may be associated with poor control of lower extremity motion during weight-bearing activities, leading to abnormal patellofemoral moti...
