OBJECTIVE To evaluate the forward shifting of cervical spinal cords in different segments of patients with Hirayama disease to determine whether the disease is self-limiting. METHODS This study was performed on 11 healthy subjects and 64 patients. According to the duration, the patients were divided into 5 groups (≤1 year, 1-2 years, 2-3 years, 3-4 years, and ≥ 4 years). Cervical magnetic res...

OBJECTIVE Cervical laminoplasty has been widely accepted as one of the major treatments for cervical myelopathy and various modifications and supplementary procedures have been devised to achieve both proper decompression and stability of the cervical spine. We present the retrospectively analyzed results of a modified unilateral open-door laminoplasty using hydroxyapatite (HA) spacers and mall...

Background: Cervical ectopic pregnancy is a rare condition with an incidence of less than 0.1% in all ectopic pregnancies. This life-threatening condition is associated with a high morbidity and mortality rates. Recently, the recommended protocol for the treatment of cervical ectopic pregnancy is fertility preservation rather than invasive surgery and hysterectomy. The aim of t...

Few studies have been conducted specifically on the dense connective tissue located in the posterior medial part of the cervical epidural space. This study was undertaken to examine the presence of this connection between the cervical dura mater and the posterior wall of spinal canal at the level of C1-C2. 30 head-neck specimens of Chinese adults were used. Gross dissection was performed on the...

Introduction: A typical vertebra has a ventral body, vertebral arch, and foramen, where the spinal cord, meninges, related vessels occupy. Depending on position amount of narrowing that occurs over time, nerve or cord may get compressed, causing pain, tingling, numbness, and/or weakness. This study was aimed at to access anteroposterior transverse diameter canal.
 Methods: All together 75 ...

A technique of cervical gastrostomy is described. Cervical gastrostomy as an alternative to the use of an indwelling nasogastric tube after cervical oesophagogastrostomy after resection for cancer has been used in six patients and appears to have certain advantages in terms of effective gastric decompression, avoiding discomfort to the patient, and simplification of postoperative nursing. It ma...

Adjunct cervical CT epidurography (CCTE) can be used to image impingement in patients with cervical brachalgia undergoing fluoroscopic-guided cervical transforaminal injection (TFI) of steroid/local anaesthetic where magnetic resonance imaging (MRI) is contraindicated. CCTE images of the 9 patients on whom the authors performed CCTE post TFI over 6 years from 1998 to 2003 were retrospectively r...

BACKGROUND Laminar screws and lateral mass screws have been increasingly used in the treatment of cervical diseases. The purpose of this study is to determine the morphological characteristics of the posterior anatomical structures of the subaxial cervical vertebrae in a northeastern Chinese population. METHODS Sixty-one consecutive patients underwent cervical spine computed tomography (CT). ...

We investigated the MR appearance and incidence of low-signal areas within the CSF of the spinal canal. Nonuniform areas of decreased signal intensity in intracranial CSF have been named the CSF flow-void sign (CFVS) and appear to be due to spin dephasing secondary to pulsatile CSF motion. Similar areas are seen in the spinal canal. The MR scans of 50 randomly selected patients, constituting a ...

OBJECTIVE In order to provide normal values of the pediatric sub-axial cervical spinal canal and vertebral body growth pattern using computed tomographic scans, a total of 318 patients less than 10 years old were included. METHODS The growth of the vertebral body and canal space was investigated using four different age groups. The Torg ratio (TR) was calculated and all patients were classifi...
