Modelling the Trunk Responses to Lumbar Manipulative Forces
Published in J. Middleton, M. L. Jones, G. N. Pande, Computer Methods in Biomechanics & Biomedical Engineering – 2, 2020
As previously mentioned, the data for the material properties of the intervertebral joints were based on published data11,18,19,20, assuming the responses to be linear. These data come from experiments that have involved relatively small numbers of cadavers and so their relation to responses of living subjects is not clear. Rib and costal cartilage property data were based on those values developed by Roberts & Chen15 but were assumed to be constant along the length of any one rib. The sacro-iliac joints were each modelled with 2 beams and their properties adjusted to match the behaviour of the joints that has been observed21. The properties of the superficial soft tissues were obtained by fitting a linear approximation to the published compressive behaviour16, 17 corresponding to the approximate range of pressures expected in this context.

Cartilage is composed of low-density chondrocytes and a relatively large portion of extracellular matrix (ECM), which is a flexible connective tissue and plays a vital role in absorbing the impact applied between joints in the bones [1]. The cartilage-related diseases include degenerative arthritis, osteomalacia, and costochondritis, etc. mostly occurring due to aging, obesity, and trauma etc. Depending on the symptoms of disease, additional problems such as severe pain and physical disability can occur [2]. Articular cartilage is difficult to regenerate when damaged and its regeneration ability is also lower compared to other tissues, because it has no blood vessels, nerves, and lymphatic vessels [3–5]. Therefore, in case of severe damage, tissue replacement for cartilage is needed and tissue engineering studies has been conducted. The cells enable healing in cartilage damage are used such as chondrocytes, bone marrow-derived stem cells, and adipose stem cells etc. [6]. We have used costal chondrocyte in this study. The costal cartilage composed of hyaline cartilage such as articular cartilage, is easy to acquire cells regardless of age, with an advantage of excellent cell division ability [7,8].
Study on chest injury and bulletproof vest protection under the combined action of blast wave and fragments

With the addition of the bulletproof board, the fragments hit the board, so the stress of skeleton and lung did not increase steeply and the stress rise was relatively moderate, as shown in Figure 8a and b. The stress of sternum and costal cartilage decreased and the damage was reduced, but the stress of rib increased and the damage aggravated. For the lung, since the blast wave first acted on the lung side through both sides of the bulletproof plate, the stress response time of the lung side was the earliest and was first injured, followed by the front and back of the lung.

Three markers are used to determine manubrium orientation in space: two placed on the median axis of the body at the upper extremity of manubrium (Mid1) and at the Louis’ Angle (Mid2), and one placed on the right first rib anterior extremity beneath clavicula (RA1). The same arrangement is used to determine the sternum orientation: two median markers at Louis’ Angle (Mid2) and lower extremity of the sternum body (Mid3) and one lateral on the second rib costal cartilage (RA2).
