INTRODUCTION: In pediatric spinal deformity the gold standard for curve surveillance remains standing full-column radiographs, but repeated exposure to ionizing radiation motivates us to look for nonradiographic solutions. This study tests a modern system of surface topography (ST) to determine whether it is reliable and reproducible. METHODS: Patients from 6 pediatric spinal deformity clinics were recruited for enrollment. Inclusion criteria were age 8-18; diagnosis of scoliosis measuring ≥10 and <50 degrees or increased kyphosis of ≥45 degrees...

BACKGROUND: Direct vertebral rotation (DVR) has gained increasing popularity for deformity correction surgery. Despite large moments applied intraoperatively during deformity correction and failure reports including screw plow, aortic abutment, and pedicle fracture, to our knowledge, the strength of thoracic spines has been unknown. Moreover, the rotational response of thoracic spines under such large torques has been unknown. PURPOSE: Simulate DVR surgical conditions to measure torsion to failure on thoracic spines and assess surgical forces...

STUDY DESIGN: Retrospective review and analysis of lateral long cassette radiographs. OBJECTIVE: The purpose of this paper is to assess whether certain radiographic features routinely seen on lumbar radiographs can predict a structural thoracic deformity. SUMMARY OF BACKGROUND DATA: Obtaining proper sagittal alignment is an essential factor contributing to favorable clinical outcomes following spinal deformity surgery. The majority of patients treated with lumbar fusions do not undergo long cassette radiographs, and therefore physicians must rely upon clinical examination to determine the presence of a structural thoracic kyphotic deformity...

Mikihiko Kumashiro, Masaki Sakai
We found that the genitalia of the male cricket Gryllus bimaculatus are equipped with an autocleaning system. The cricket keeps its genitalia clean by removing foreign matter and endogenous waste. Morphological study showed that the membrane complex consists of a median pouch and a genital chamber floor covered by small scales, each of which has a base of approximately 10 µm in width and a fringe with 5-10 spines 3-20 µm in length. The scales are arranged symmetrically about the midline, curving gradually in the lateral direction and continuing to the lateral pouch serving as a trash container...

PURPOSE: The Cobb angle as an objective measure is used to determine the progression of deformity, and is the basis in the planning of conservative and surgical treatment. However, studies have shown that the Cobb angle has two limitations: an inter- and intraobserver variability of the measurement is approximately 3-5 degrees, and high variability regarding the definition of the end vertebra. Scoliosis is a three-dimensional (3D) pathology, and 3D pathologies cannot be completely assessed by two-dimensional (2D) methods, like 2D radiography...
