Though the pathogenesis of Legg-Calve-Perthes disease (LCPD) is unknown, repetitive microtrauma resulting in deformity has been postulated. The purpose of this study is to trial a novel upright MRI scanner, to determine whether any deformation occurs in femoral heads affected by LCPD with weightbearing. Children affected by LCPD were recruited for analysis. Children received both standing weightbearing and supine scans in the MROpen upright MRI scanner, for coronal T1 GFE sequences, both hips in field of view. Parameters of femoral head height, width, and lateral extrusion of affected and unaffected hips were assessed by two independent raters, repeated at a one month interval. Inter- and intraclass correlation coefficients were determined. Standing and supine measurements were compared for each femoral head.Aims
Methods
There is increasing evidence that flexible flatfoot (FF) can
lead to symptoms and impairment in health-related quality of life.
As such we undertook an observational study investigating the aetiology
of this condition, to help inform management. The hypothesis was
that as well as increased body mass index (BMI) and increased flexibility of
the lower limb, an absent anterior subtalar articulation would be
associated with a flatter foot posture. A total of 84 children aged between eight and 15 years old were
prospectively recruited. The BMI for each child was calculated,
flexibility was assessed using the lower limb assessment scale (LLAS)
and foot posture was quantified using the arch height index (AHI).
Each child underwent a sagittal T1-weighted MRI scan of at least
one foot. Aims
