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...

In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment of the femoral component in total knee arthroplasty (TKA). There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittal femoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line (DACL) ...

STUDY DESIGN A retrospective radiographic study. PURPOSE To verify the correlation of sagittal and coronal plane changes after selective thoracic fusion in main thoracic (MT) adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE Sagittal plane deformity is known to be essential in the evolution of scoliosis. METHODS Twenty-eight MT AIS patients treated by anterior selective thorac...

introduction: determining the proper angle for inserting central venous catheter (cv line) is of great importance for decreasing the complications and increasing success rate. the present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization.  methods: in the present case series study, candidate patients for catheterization of the right i...

STUDY DESIGN Retrospective analysis. OBJECTIVE To evaluate the correlation and reliability of cervical sagittal alignment parameters obtained from lateral cervical radiographs (XRs) compared with lateral whole-body stereoradiographs (SRs). METHODS We evaluated adults with cervical deformity using both lateral XRs and lateral SRs obtained within 1 week of each other between 2010 and 2014. XR...
