Introduction: Osteogenesis Imperfecta (OI) is a connective tissue disorder, which is the most common cause of genetic osteoporosis characterized by long bone deformities and fractures. The key defect is the qualitative and quantitative lack of type I collagen. The primary target in these patients is to fix deformities and to prevent fractures. The surgical application is often a basic surgical ...

Objectives: The aim of this study was to determine the prevalence of flat foot in a population of 7-12 year old students and to investigate the relationship between flat foot and age and sex. Methods: In this cross-sectional study, a total of 945 students (460 girls and 485 boys) were examined. The presence of flatfoot and the degree of its severity according to Tachdjian's system of grading...

Poliomyelitis is an infectious disease caused by a neurotrophic virus targeting anterior horn cells of lower motor neurons resulting in flaccid paralysis and represents a common condition in developing countries, and even nowadays, most of both treated and untreated cases result in foot deformities. Between 1994 and 2007, 27 patients were treated by classic ring Ilizarov fixator, aiming at prod...

[Purpose] The purpose of this study was to investigate the changes in muscle activation of the trunk and lower extremities and plantar foot pressure due to backpack loads of 0, 10, 15, and 20% of body weight during level walking in individuals with flatfoot. [Methods] Fourteen young flatfoot subjects and 12 normal foot subjects participated in this study. In each session, the subjects were assi...

Previous studies have shown that the effective rocker shape of the physiologic ankle-foot system during standing and fore-aft swaying is much flatter than that used during walking, which indicates a more stable base of support for the standing/swaying activity. Previous work suggests that flat regions within the effective rocker shapes of prosthetic ankle-foot systems could provide enhanced sta...

Postburn severe edge ankle dorsiflexion contractures are the result of deep burn of the lateral joint surface. The contracture affects the foot motions, impairs the lower extremity function and slows down its development in pediatric patients; scars and tissue defects cause severe deformities. Therefore, early reconstruction is needed. Review of literature shows that ankle scar contractures are...

OBJECTIVES In this study, we evaluated the effects of the distance of the legs from the midline on alignment and angles of the lower extremities in orthoroentgenograms. PATIENTS AND METHODS Between March 2012 and April 2013, 95 limbs of 56 patients with varus deformity who underwent orthoroentgenogram to identify the amount of joint laxity in two positions were included in this study. The ini...

[Purpose] The purpose of the study was to discover why people who have flat feet show a higher risk of damage to the musculoskeletal system than those who have normal feet. Furthermore, we examined the kinematic differences in the lower extremity between flat feet and normal feet in individuals on an ascending slope using three-dimensional gait analysis. [Subjects] This study was conducted on 3...

[Purpose] The purpose of this study was to evaluate the correlation between intrinsic patellofemoral pain syndrome (PFPS) in young adults and lower extremity biomechanics. [Subjects] This experiment was carried out with sixty (24 men and 32 women), who are normal university students as subjects. [Methods] All subjects underwent 3 clinical evaluations. For distinguishing the intrinsic PFPS from ...
