The purpose of this study was to test the hypothesis that the presence of a subaortic ridge associated with a ventricular septal defect (VSD) is related to a malaligned ventricular septum caused by anterior or posterior deviation of the infundibular septum with or without obstructive lesions of the aortic arch. Thirty-two of 295 patients in whom a diagnosis of VSD was made by two-dimensional ec...

BACKGROUND For large scale epidemiological studies clinical assessments and radiographs can be impractical and expensive to apply to more than just a sample of the population examined. The study objectives were to develop and validate two novel instruments for self-reported knee malalignment and foot rotation suitable for use in questionnaire studies of knee pain and osteoarthritis. METHODS T...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

Background: There are numerous etiologies relating to physeal arrest. The clinical manifestations of arrest may include limb length discrepancy (LLD) and bone malalignment, especially in younger children with more growth ahead them.

STUDY DESIGN Retrospective study. OBJECTIVE To assess the relationship between sagittal alignment of the cervical spine and patient-reported health-related quality-of-life scores following multilevel posterior cervical fusion, and to explore whether an analogous relationship exists in the cervical spine using T1 slope minus C2-C7 lordosis (T1S-CL). SUMMARY OF BACKGROUND DATA A recent study ...
