Lateral spinal profile in school-screening referrals with and without late onset idiopathic scoliosis 10 degrees-20 degrees.
The aim of this report is a) to study the lateral spinal profile, (LSP), in school-screening referrals with and without late onset idiopathic scoliosis of small curves 10 degrees - 20 degrees Cobb angle and b) to validate LSP's aetiological importance in idiopathic scoliosis pathobiomechanics. ⋯ The observed differences of the LSP are mainly located at the lumbar spine, suggesting that factors acting on the lumbar spine in sagittal plane contribute to the development of AIS. The minor hypokyphosis of the thoracic spine and its minimal differences observed in the studied small curves with nonscoliotics in this report add to the view that the reduced kyphosis, by facilitating axial rotation, could be viewed as being permissive, rather than as aetiological, in the pathogenesis of idiopathic scoliosis.

Future progress in healthcare and medicine depends on today's investment in research, development, and education. We cannot leave such urgent issues to determine themselves, but rather must actively collaborate to ensure a stable healthcare system. This chapter describes efforts made by leading experts in industry, government, and academia to better ascertain future healthcare management. ⋯ Deliberating and reviewing plans before taking action will accelerate progress as it will (1) save costs, (2) encourage compliance, (3) improve clinical outcomes, and (4) ensure greater patient satisfaction. What we must resolve is: How can we invest a couple billion dollars to save hundreds of billions and, most importantly, increase human health in the future. A new branch of science, Biomechatronics, with millions of Intelligent Caring Creatures- is the answer.

Spine deformity correlates better than trunk deformity with idiopathic scoliosis patients' quality of life questionnaire responses.
To determine whether either spine or trunk deformity measurements correlate with patients quality of life questionnaire responses. ⋯ Spine deformity correlates well with quality of life questionnaire responses whereas trunk deformity magnitude does not. This is somewhat surprising as it is the trunk deformity that the patient can they themselves see. These findings illustrate the pitfalls of assuming what is important to the patient based on clinical measurements.

Study of the rib cage deformity in children with 10 degrees-20 degrees of Cobb angle late onset idiopathic scoliosis, using rib-vertebra angles--aetiologic implications.
The aim of the study is to compare the rib-vertebra angles (RVAs) between children with 10 degrees - 20 degrees of Cobb angle late onset idiopathic scoliosis (LOIS) and non-scoliotic children. ⋯ It has been reported that RVAs is an expression of the resultant muscle forces, which act on each rib. It was also suggested that RVA asymmetries by weakening the spinal rotation-defending system are aetiological for idiopathic scoliosis, (Burwell et al 1992). This study shows that scoliotic children with small curves have underdeveloped thoracic cage compared to nonscoliotic counterparts. The differences are more apparent in the scoliotic children with thoracic curves. It is suggested that the differences of the RVAs between right and left side in this group are an expression of asymmetric muscle forces acting on the thoracic cage. It is concluded that asymmetric muscle forces participate in the pathogenesis of idiopathic scoliosis on the thoracic cage, which deforms early.

Successful applications of haptic displays are limited to tool-based interfaces that simulate haptic effects on surgical and other medical instruments. However, no satisfactory haptic display exist so far, that enable the simulation of high fidelity palpation of human tissue or body segments. Existing approaches developed for medical training fail due to unrealistic haptic effects, time-consuming donning and doffing, and inconvenient use (e.g., mechatronic tactile and kinesthetic displays) or due to restricted function and adjustability (e.g., passive mannequins). ⋯ The new haptic display has been verified with a setup developed for the training of functional joint evaluation after knee injuries. Compared to classical approaches, this display is convenient to use, provides realistic tactile properties and can be partly adjusted to different system properties (e.g. pathological joint properties). This kind of new interface can be applied to many different medical applications, where the clinician directly touches human limbs or tissue, such as in obstetrics, reanimation, organ palpation, etc.
