Introduction Sagittal spinal deformity can be defined as pathological deviations of the posterior (kyphosis) or anterior (lordosis) physiological curve of the spine on the sagittal plane due to structural alterations of discs, ligaments, and bony structures as well as myofascial tensional imbalances. Deviations can present as either excessive (thoracic hyperkyphosis or curved back, lumbar hyperlordosis), reduced (flat back, concave back, hypolordosis, lumbar kyphosis) or altered in their normal distribution (lumbar kyphosis, cervico-dorsal kyphosis) and may have various aetiologies (Shelton, 2007). It is necessary to distinguish between structured curves and correctable functional curves in pubescent subjects, even though correctable curves (curved back, postural hyperkyphosis, postural lumbar hyperlordosis) can potentially evolve in terms of stiffness and structural changes. In adults, hyperkyphosis is mostly structural and cannot be completely reversed. In reference to the Cobb angle measured on X

One of the main topics of the last Fascia Research Congress (Washington, 17e21 September 2015) was the terminology about fascia. Many researchers are convinced that the indiscriminate use of the term “fascia” in reference to various types of connective tissue often leads to confusion. Furthermore, inconsistent use of anatomical terms makes it difficult to compare results across research studies and to draw generalized conclusions (Langevin, 2014). This situa- tion may be comparable to a time in anatomy history described by Adstrum (2014): “more than 50,000 terms were used to identify 5000 structures, so, anatomical ter- minology was in a state of chaos, incoherent, full of
