Incidence and Skeletal Features of Developmental Cervical and Lumbar Spinal Stenosis.

Study Design: Cross-sectional study.

Purpose: To report the prevalence and relationship of developmental cervical and lumbar spinal stenosis (DCSS and DLSS) with the bone parameters of the skull and extremities.

Overview Of Literature: DCSS and DLSS are found occasionally in daily practice.

The new imaging findings: "Passing spine" without kissing.

Case-control studies by examining the lumbar spine computed tomography (CT) findings focusing on the spinous processes."Passing spine" was defined as a lumbar degenerative change observed on CT images. In contrast, kissing spine, which is also an image finding, has been acknowledged as an established clinical condition.

Pedicle Screw System May Not Control Severe Spinal Rotational Instability.

Study Design: An in vitro biomechanical study.

Objective: The purpose of this study is to discuss whether pedicle screw systems can control spinal rotational instability in a functional spinal unit of lumbar spine on human cadaver.

Summary Of Background Data: Rotational experiments using deer lumbar cadaveric models showed that rotational range of motion (ROM) of the model fixed by a pedicle screw system with crosslinking after total facetectomy for both the sides was larger than that in the intact model, and stated that spinal rotational instability could not be controlled using a pedicle screw system.

A survey of workplace violence against physicians in the hospitals, Myanmar.

Objective: Workplace violence in hospitals is recently becoming a major global concern in many countries. However, in Myanmar, we have felt that patients and their families have rarely made unreasonable complaints in hospitals, and then, the purpose of this study is to report the current state of workplace violence in hospitals in Myanmar. Participants are 196 physicians (108 males and 88 females) in hospitals in Myanmar.

Biomechanical Stability of a Cross-Rod Connection with a Pedicle Screw System.

BACKGROUND Surgery with pedicle screw instrumentation does not provide sufficient torsional stability. This leads to pseudoarthrosis, loosening of the pedicle screws, and, ultimately, implant failure. MATERIAL AND METHODS Functional spinal units from 18 deer were evaluated using a 6-axis material testing machine.

Tumoral calcinosis in the cervical spine: a case report and review of the literature.

Background: Tumoral calcinosis is rarely located in spine. A 55-year-old Japanese woman with cervical tumoral calcinosis is presented, along with a review of the literature relating to tumoral calcinosis in the spine. We discussed the etiology, diagnosis, and management of this condition.

Characteristics of Patients with High Lie Scores in a Personality Test.

Background: It is reported that persons with high Lie score (L score) of a personality test are aggressively self-confident and are also related to depression or schizophrenia In this study, we examined the characteristics of patients with high L scores on the Maudsley Personality Inventory (MPI) and examined the significance of the L score.

Materials And Methods: We collected the data of 10789 subjects and examined the relationship between L score or the number of characteristic biased persons and the parameters of age, sex, education level, occupation, and degree of pain. Furthermore, we examined the changes in extraversion-introversion (E score), neuroticism (N score), and L scores at approximately 1 year after surgery in 1711 patients who underwent surgery at our university hospital or affiliated hospitals.

Relief of Lower Back and Leg Pain after Myelography.

Introduction: It is well-known that many patients will have adverse reactions such as headache and nausea after undergoing myelography, but we have often seen cases where symptoms such as lower back pain and leg pain were alleviated following myelography. To the best of our knowledge, such clinical cases of post-myelographic alleviation have not been reported.

Materials And Methods: A total of 325 patients with a degenerative lumbar spinal disorder who underwent myelography were prospectively investigated at four hospitals from April 2012 to March 2014 to survey the post-myelographic alleviation of lower back and leg pain prospectively.

Biomechanical study of rotational micromovement of the pedicle screw.

Background: In regard to the fixation using a pedicle screw (PS) and rod system, the mechanism from the onset of the clear zone up to the development of loosening of the pedicle screw is not completely clarified. The purpose of this study is to determine the cause of the pedicle screw loosening by performing a biomechanical study with three-dimensional movie analysis.

Methods: Ten PS fixation model of the lumbar spines (L3-4) of boar cadavers were used.
