KEY BONES AND HANGING BONES.
“In the treatment of posture errors, the fundamental aim must be to make the mechanism of the body as perfect as possible, because it is precisely on this that the excellent state of health and the resistance of the disease depend” A. Benichou (1988)
These bones have their own peculiarity, they are closely connected to the fascial system, it seems that the organization of our body has decided to consider them structural shock absorbers, what does this definition mean? The body has decided to discharge its tensions on these structures to maintain its functionality and cushion the internal tensions of our body and the external ones gravity, the force of the ground and of course any external force.
The characteristics between key bones and hanging bones are totally different.
The key bones are: The cuboid, fibula, pubis, clavicle and zygomaticus.
The suspended bones are: the patella, the sacrum, the sternum and the hyoid.
The key bones are fascial relays, what do we mean by this phrase, their role is to maintain the correct physiology of the fascia allowing the body to maintain its fluid and nervous physiology.
If there are important or even continuous fascial strain at the fascial level, the body prefers to create a major somatic dysfunction and also lose most of its movement. We can say that in order to be able to maintain a standard of quality of the functions of the fluids of our body, it prefers to go into somatic dysfunction, these dysfunctions always have a very bad quality of movement, the key and suspended bones will have to allow physiology between the various body districts.
By analyzing them, we can also give other functional readings.
The cuboid is the key bone of the foot, its physiology associated with the scaphoid to be able to manage the dynamism of the movement of the foot, the calcaneus and talus have the function of loading and allowing the leg to move above, the front part of the foot is the push, the momentum in walking, the cuboid and the scaphoid as an area of cushioning must adapt to allow the physiology of the movement of the foot.
Let’s not forget the distant correlations of the cushioning areas, its dysfunction can be the compensation of the diaphragms that are above, Fulford lozenges
The cuboid is closely connected to the external surface chain, so we can find it dysfunctional also because of the chain.
The fibula is the key bone of the lower limb, all the fasciae in the leg are inserted on it. It will adapt to the loss of quality of movement of the ankle and knee, it is common in traumas.
It is also closely connected with the external surface chain and the cushioning area of the knee.
In the patient who has chronic pain due to knee and ankle dysfunctions tends to walk in an analgesic scheme, this movement strategy will tend to exploit the intra-osseous membrane of the leg, as the fulcrum of walking, with this movement strategy the fibula will go into dysfunction.
There are two other causes that disturb the physiology of the intra-osseous membrane and consequently the movement of the fibula: balance and respiration, which require a strong compensatory tension to the intra-osseous membrane.
The pubis is the key bone of the pelvis, it is closely connected to the anterior superficial fascial chain and the urogynecological tissues, its dysfunctions are the demonstration of a problem of the pelvis or contents, or a compensation in relation to the areas of cushioning.
The clavicle is the key bone of the trunk, its connections are with the rib cage, with the upper limb, with the pleural dome and the cervical fascia, it is a fundamental element of the upper thoracic outlet.
At the cranial level we have the cheekbone as a key bone, all the exocranial fasciae are inserted on it.
Suspended bones have a different characteristic of suspended bones, they must maintain this characteristic of suspension, mobility and plasticity. But I often find them hypomobilious and dense, a sign of lack of compensation.
They have a strong neurovegetative and emotional correlation, so the manual approach must be courteous.
The patella adapts to problems related to the knee, the quadriceps contracts to compensate for the dysfunctions of the knee itself. The problems of balance, the patient who puts weight on the heels, even the movement of the muscles of the eyes, if it is not synergistic with each other, the functions of the two excretions, lung and kidney, disturb it and make it lose its mobility.
The sacrum, always dysfunctional, tries to live suspended, but does not succeed, has intimate correlations with the other bones of the pelvis, the posterior superficial fascial chain, the visceral fascial structures of the pelvis and pelvis and finally the dura mater. It is difficult for him to maintain his suspended role.
At the level of the thorax we have the sternum, a structure that has relations with the anterior superficial fascial chain, inside the structures of the mediastinum and respiratory functions, more correctly called the central, mixed and peripheral deep fascial chains. The sternum is emotionally linked to anxiety and panic, in these subjects its structure will be very dense.
The hyoid is suspended in the throat, it is part of the cushioning area together with the mandible, it involves all the fascial structures of the anterior neck on it, puny and weak, emotionally it is linked to our oral communication.
Key and suspended bones must always be checked, corrected, but the fundamental point is to understand why they have lost mobility. Definitely for a fee, so you have to go look elsewhere.
Their role is to allow the body to maintain an adaptability to maintain homeostasis, even at the expense of almost totally losing their mobility.
