Closure of fascia and subcutaneous tissues is done to eliminate dead space to minimize the risk of hematoma formation and the development of infection. While studies report that the strength of a fascial repair increases slowly over several months, the empiric convention is to suture this tissue with either running or interrupted braided absorbable material. Subcutaneous closure, either continuous or interrupted, helps provide eversion of the tissue and prolonged wound support.83 Despite the lack of scientific basis to justify closure of subcutaneous fatty tissue because of poor suture holding qualities, many surgeons place sutures at this site without significant difference in the incidence of subcutaneous hematomas in hip replacement surgery, with authors of one study recommending careful hemostasis.84
Biomechanical modelling and simulation of foot and ankle
Published in Youlian Hong, Roger Bartlett, Routledge Handbook of Biomechanics and Human Movement Science, 2008
Cheung et al.11 developed a linearly elastic FE ankle-foot model from MR images, which took into consideration large deformations and interfacial slip/friction conditions, consisted of 28 bony structures, 72 ligaments and the plantar fascia embedded in a volume of encapsulated soft tissue. A sensitivity study was conducted on the Young’s modulus (0–700 MPa) of plantar fascia, which was found to be an important stabilizing structure of the longitudinal arch during weight-bearing. Decreasing the stiffness of plantar fascia reduced the arch height and increased the strains of the long and short plantar and spring ligaments. Fasciotomy increased the strains of the plantar ligaments and intensified stress in the midfoot and metatarsal bones. Fasciotomy did not lead to the total collapse of foot arch even with additional dissection of the long plantar ligaments. The effect of partial and complete plantar fascia release was also investigated7 and it was implicated that plantar fascia release may provide relief of focal stresses and associated heel pain. However, these surgical procedures, especially complete fascia release, were compromised by increased strains of the plantar ligaments and intensified stress in the midfoot and metatarsal bones and may lead to arch instability and associated midfoot syndromes.
Functional Anatomy and Biomechanics
Published in Emeric Arus, Biomechanics of Human Motion, 2017
These fasciae are fibrous membranes which cover, support, and separate muscles. Fascia may be a superficial or subcutaneous matter which allows free movement of the skin, or it may be a deep, enveloping and binding sheet of connective tissue over the muscles. Here are several fasciae:

A compartment is generally referred to as a group of muscles, blood vessels, organs, bones, and nerve fibers held together by a thin but tough membrane known as the fascia. It not only holds the internal parts together but also acts as a protective layer [1]. The body contains three types of fascia: visceral fascia, superficial fascia, and deep fascia. The superficial fascia is located just beneath the skin in the outermost layer. Bones, muscles, nerves, and blood vessels are primarily associated with deep fascia. The connective tissue present within the deep fascia restricts the ability of its muscles to change form. The visceral fascia contains organs such as the heart, lungs, and abdomen that are located within cavities [1,2].
Assessment of the thigh skin and fascia strains during knee flexion-extension: an ex-vivo study

Fascia is a fibrous connective tissue present all over the body. This study focuses on the deep fascia that is overlying muscles of the outer thigh. Indeed, fascia lata is involved in various pathologies, such as iliotibial band syndrome, inflammatory lesions, traumatic injuries etc. (Huang et al. 2013). This fascia has a sheathing effect on muscles and a stabiliser effect on the knee and hip joints during movements (Eng et al. 2014); however, these sheathing and stabiliser effects have not been quantified yet.
