Results A 21 year old primigravid woman admitted to our clinic with suspicion of cervical incompetence at 22 weeks of gestation. She complained of light vaginal bleeding and a vaginal mass. She did not have any pain. Her past medical history was uneventful. A detailed abdominal 2D ultrasound scan was performed to verify the presence of the pregnancy and research for associated anomalies. The US...

The ratio of the sagittal diameter of the cervical canal to the corresponding diameter of the vertebral body has been described as a reliable means for assessing stenosis of the canal and detecting those at risk of cervical neuropraxia. The use of ratio techniques has the advantage of avoiding variation in magnification when direct measurements are made from plain radiographs. We examined the r...

Study Design Retrospective cohort study. Objective The objective was to measure the change of flavum ligament diameter during positional changes of the cervical spine using kinetic magnetic resonance imaging (MRI) and to examine the correlational diameter changes of the flavum ligament, disk bulging, and the spinal canal from extension to flexion positions. Methods One hundred eight-nine patien...

Background: Abnormal uterine bleeding (AUB) is one of the most common clinical problems in gynecology. Transvaginal sonography (TVS) and hysteroscopy are two diagnostic methods for patients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done in clinic with minimal discomfort and much lower expense than operative room. Materials and Methods: In our clinical trial stu...

OBJECTIVE To quantify changes in the diameter of the vertebral canal with flexion and extension in the cervical vertebral column. STUDY DESIGN Cadaveric biomechanical study. SAMPLE POPULATION Cadaveric canine cervical vertebral column (n = 16 dogs). METHODS All vertebral columns were evaluated with MRI. Group 1 consisted of 8 normal vertebral columns. Group 2 included 8 vertebral columns ...

STUDY DESIGN A cross-sectional study. OBJECTIVE This study aims to investigate the correlation of the cervical canal and spinal cord size, and evaluate whether the size of the spinal cord relative to the spinal canal is a risk factor for development of cervical spinal cord compression (SCC). SUMMARY OF BACKGROUND DATA There is little knowledge regarding the relationship between cervical bon...

embryo transfer and its related factors received little clinical attention and had been, until recently, the most inefficient step in in-vitro fertilization (ivf). factors which appear to influence implantation rates are: contamination of the catheter tip with cervical bacteria, stimulation of uterine contractions during the procedure, the type of catheter, ultrasound guidance during the transf...

Background The aim of this study was to determine the incidence of coexisting symptomatic lumbar canal stenosis (LCS) in patients after surgery for cervical spondylotic myelopathy (CSM) and identify possible predictive factors associated with it. Materials and methods We retrospectively reviewed patients with CSM at our institution between January 2005 and December 2015. Clinical and radiogra...

Cervical spondylosis was defined by Brain (1948), by Brain, Northfield, and Wilkinson (1952), and by Frykholm (1951). Its essential features are protrusion of the annulus fibrosus and changes in the adjacent vertebral margins. The size of the cervical spinal canal may play a major part in the neurological manifestations of cervical spondylosis. The antero-posterior diameters of the cervical can...
