We undertook a comparative study of magnetic resonance imaging (MRI) vertebral morphometry of thoracic vertebrae of girls with adolescent idiopathic thoracic scoliosis (AIS) and age and gender-matched normal subjects, in order to investigate abnormal differential growth of the anterior and posterior elements of the thoracic vertebrae in patients with(More)
STUDY DESIGN A cross-sectional study of the balance control in adolescents with idiopathic scoliosis. OBJECTIVE.: To investigate the relationship among somatosensory function, balance control, and adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Balance control requires the contribution of somatosensory, visual, and vestibular inputs.(More)
STUDY DESIGN Conventional and phase-contrast magnetic resonance (MR) imaging were used to evaluate the morphology and cerebrospinal fluid (CSF) flow dynamics at craniocervical junction in adolescent idiopathic scoliosis (AIS). OBJECTIVES To determine the morphology of cerebellar tonsil, foramen magnum, and dynamic flow of CSF at the craniocervical(More)
STUDY DESIGN Magnetic resonance (MR) imaging and multiplanar reconstruction was used to evaluate the morphology and relative position of the spinal cord in adolescent idiopathic scoliosis (AIS). OBJECTIVE To determine the longitudinal and cross-sectional morphology of spinal cord in AIS subjects versus normal controls and their correlation with relative(More)
With the use of multiplanar reformat Magnetic Resonance imaging, AIS patients were found to have significantly reduced pedicle widths on concavity. Pattern of vertebral asymmetry was also exaggerated with smaller pedicle width, length and area on concavity. The cord appeared more roundish and was deviated to the concavity at apical vertebra in AIS. A(More)
In this pilot cross-sectional study, the effectiveness of rigid spinal orthoses in the correction of spinal curvature of 14 patients with moderate adolescent idiopathic scoliosis (AIS) at different recumbent positions (supine, prone, right and left decubitus) was investigated. Using magnetic resonance (MR) imaging and multi-planar reconstruction technique,(More)
OBJECTIVES To identify the diagnostic, therapeutic, and prognostic values of transforaminal epidural steroid injection as interventional rehabilitation for lumbar radiculopathy. SETTING Regional hospital, Hong Kong. PATIENTS A total of 232 Chinese patients with lumbar radiculopathy attributed to disc herniation or spinal stenosis received transforaminal(More)
STUDY DESIGN Magnetic resonance imaging (MRI) was used to compare quantitatively the position of the cerebellar tonsil in neurologically normal adolescents with that in idiopathic scoliosis (AIS) patients and age-matched healthy controls. OBJECTIVES To redefine the normal reference level of the cerebellar tonsil in healthy adolescents and to compare the(More)
BACKGROUND Accurate skeletal maturity assessment is important to guide clinical evaluation of idiopathic scoliosis, but commonly used methods are inadequate or too complex for rapid clinical use. The objective of the study was to propose a new simplified staging method, called the thumb ossification composite index (TOCI), based on the ossification pattern(More)
BACKGROUND The objective of this study is to evaluate the effects of the Multi-disciplinary Orthopaedics Rehabilitation Empowerment (MORE) Program on reducing chronic disability among injured workers and improving efficiency of work rehabilitation process. METHODS A cohort of patients with workplace injuries in the lower back were recruited from(More)
