Ectopic/aberrant cervical thymic tissue is a rare cause of neck mass and usually detected incidentally. Aberrant thymic tissue can occur anywhere in the course of thymic descent from the angle of the mandible to the superior mediastinum. We report a case of aberrant cervical thymus demonstrated by ultrasound.

Anterior cervical surgery is commonly used for cervical vertebral body lesions. However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk (CST) ganglia in Chinese cadaver specimens. A total of 32 adult cadavers were studied. We delin...

The associations between dimensions of the first cervical vertebra, atlas, and a representative set of craniofacial and postural variables were studied on cephalometric radiographs of a sample of 103 adult males aged 22-30 years, recorded in the natural head position (mirror position). Atlas morphology was expressed by nine variables, linear and angular craniofacial dimensions by 27 variables, ...

[Purpose] The present study aimed to conduct a comparative analysis of changes in mechanical characteristics of cervical muscles and cervical posture in patients with cervicogenic headache following exercise program intervention in order to present effective treatment methods for such patients. [Subjects and Methods] A total of 30 patients with cervicogenic headache were recruited and 15 patien...

STUDY DESIGN The motion of each cervical vertebra during simulated rear-end car collisions was analyzed. OBJECTIVES To clarify the mechanism of zygapophysial joint injury during whiplash loading. SUMMARY OF BACKGROUND DATA The zygapophysial joint is the suspected origin of neck pain after rear-end car collision. However, no studies have been conducted on the mechanisms of zygapophysial join...

BACKGROUND Knowledge of the morphometric anatomy of cervical pedicles is essential for the safe and accurate placement of pedicle screws during instrumentation of the cervical spine. Screw placement in the lumbar and thoracic vertebrae is considered as a safe practice, unlike the cervical vertebrae due to the risks involved. There are few reports on this technique. The little available informat...

A computational analysis of flow in simplex fuel atomizers using the arbitrary-Lagrangian–Eulerian method is presented. It is well established that the geometry of an atomizer plays an important role in governing its performance. We have investigated the effect on atomizer performance of four geometric parameters, namely, inlet slot angle, spin chamber convergence angle, trumpet angle, and trum...

STUDY DESIGN Prospective study. OBJECTIVES To analyze the sagittal balance after single-level cervical disc replacement (CDR) and range of motion (ROM). To define clinical and radiologic parameters those have a significant correlation with segmental and overall cervical curvature after CDR. SUMMARY OF BACKGROUND DATA Clinical outcomes and ROM after CDR with Mobi-C (LDR, Troyes, France) pros...

STUDY DESIGN Technique description and retrospective data analysis. PURPOSE To describe the technique of cervical kyphosis correction with partial facetectomies and evaluate the outcome of single-stage posterior decompression and kyphosis correction in multilevel cervical myelopathy. OVERVIEW OF LITERATURE Kyphosis correction in multilevel cervical myelopathy involves anterior and posterior...

Introduction: To determine whether the examination of uterocervical angle anterior, posterior, cervical length, and combination can be used as a predictor successful delay in labor patients with threatened preterm birth (PTB). Methods: This is prospective cohort analytical observational study 44 women admitted to our hospital gestational age 28-36 weeks diagnosed birth. Cervical anterior angle,...
