🔈 PELVIS TENSEGRITY
⠀
The pelvis is the center of gravity and the largest bony complex in the human body.
The pelvis and sacrum are linked via strong ligaments and muscles, creating a tension system that works with the compression-bearing bones to create a local tensegrity system.
⠀
These ligaments are visualized in the picture, they include the posterior SI ligaments (Iliotransversosacral, Axile, Zaglas, Bichat), anterior SI ligaments, the iliolumbar ligaments and the sacrotuberous and sacrospinous ligaments.
⠀
Locally, these ligaments need to have balanced tension to maintain SI joint integrity and normal bone positions in space.
If one of these ligaments is injured and loses its optimal tension/quality, disruption of the tensegrity balance ensues.
This leads to increased compression stress in the pelvis/SI and hip joints, but also leads to distortion of the global tensegrity of the body.
⠀
For example, in the picture we can see a normal, balanced pelvis icosahedron on the left with the horizontal balance beams through L4 and the greater trochanter did the femurs.
On the right, we can see the consequence of an injury to the right SI joint/ligament complex. This leads to pelvic and sacral shifting, unleveling of L3 (blue dot) and functional scoliosis, anterior-inferior shift of the left ilium, valgus stress in the left knee, and pronation stress in the left foot-ankle.
The white arrow represents the downward compressive force of gravity. If the tensegrity is balanced, the body can adequately resist gravity without breakdown.
⠀
Disruption of this tensegrity system is the source of joint degeneration and pain, all results of decreased space/compression in the joints.
⠀
This is but one example of how loss of connective tissue tension/quality leads to compression stresses as well as local and global distortions of the tensegrity system.
⠀
In biotensegrity, micro affects macro, local affects global!
