To assess facial form, one has to determine the size, position, orientation, shape, and symmetry of the different facial units. Many of these assessments require a frame of reference. The customary coordinate system used for these assessments is the 'standard anatomical frame of reference', a three-dimensional Cartesian system made by three planes: the sagittal, the axial, and the coronal. Cons...

STUDY DESIGN A prospective imaging study. PURPOSE To characterize the distribution of the global sagittal postural patterns in asymptomatic Chinese adults using Roussouly classification. OVERVIEW OF LITERATURE The norms of sagittal parameters in asymptomatic Chinese population have been previously described, but no report described their global sagittal postural patterns as characterized by...

BACKGROUND Previous studies report an increase in thoracic kyphosis after anterior approaches and a flattening of sagittal contours following posterior approaches. Difficulties with measuring sagittal parameters on radiographs are avoided with reformatted sagittal CT reconstructions due to the superior endplate clarity afforded by this imaging modality. METHODS A prospective study of 30 Lenke...

In a canine model of global cerebral ischemia, 6 dogs received a saline placebo prior to the event and 5 received 12.5 mg/kg ibuprofen. Cerebral venous outflow from the confluence of the sagittal and transverse sinuses, systolic and diastolic arterial pressure, cardiac output, pH, Paco2, Pao2, and arterial and sagittal sinus thromboxane B2 and 6-keto-PGF1 alpha were measured at intervals up to ...

The goal of any ambulatory patient is to maintain a horizontal gaze with the least amount of energy expenditure. With progressive deformity, and in particular sagittal malalignment, significant compensatory mechanisms must be used to achieve this goal. Each pelvis dictates the amount of lumbar lordosis required through its morphometric parameter pelvic incidence. The pelvis may compensate for d...

OBJECTIVE To investigate the relationship between prevalence of cardiopulmonary resuscitation (CPR) related thoracic injury and patients' volume dimensions. STUDY DESIGN Observational study. PLACE AND DURATION OF Kartal Dr. Lutfi Kirdar City Hospital, Istanbul, Turkey, from August 2015 to 2019. METHODOLOGY Patients, who were in hospital due a non-traumatic cause, had experienced cardiac arrest ...

restoration of the sagittal alignment is one of the fundamental goals in scoliosis correction surgery. having an increase in popularity of segmental spinal instrumentation, thoracic kyphosis (tk) is often sacrificed to achieve frontal and axial plane correction. patients with a lenke type 1 deformity underwent selective thoracic fusion (lowest instrumented vertebra of t12 or l1) using correctiv...

To make artificial knee joints have lower long-term wear rate, a new method for reformed design of sagittal femoral condylar geometry based on TRIZ (Theory of Inventive Problem Solving) was proposed. Firstly, according to the development history of sagittal femoral condylar geometry and evolution theory of TRIZ, future state of the evolution line of femoral condylar geometry in sagittal plane w...

The purpose of this study was to determine the incidence and degree of sagittal plane deformity that occurs during limb lengthening of the femur. Twenty-one patients (25 limbs) were identified who underwent femoral lengthening. The limbs were lengthened a mean of 6.1 cm, and mean follow-up was 1.5 years. The immediate postoperative deformity in the sagittal plane was 8.3°; this deformity did no...

background and objective: magnetic resonance imaging (mri) is the most sensitive technique to detect multiple sclerosis (ms) plaques in central nervous system. in some cases, the patients who were suspected to ms, whereas mri images are normal, but whether patients don’t have ms plaques or mri images are not enough optimized enough in order to show ms plaques? the aim of the current study is ev...
