HIP STABILITY AND TENSEGRITY SYSTEM ⠀ [FUNCTIONAL ANATOMY] ⠀ The hip joint also known as the femoroacetabular joint is the largest spheroidal joint in the human body and is capable of creating tremendous forces. ⠀ The function of the hip joint is dependent on its local stability, which is governed by the passive ligamentous capsule and labrum as well as the active muscle pulleys. ⠀ In the first picture, the arrows represent the muscles that effect the hip joint/proximal femur directly. They all balance each other’s pull through a tensegrity system. They are: 1. Psoas Major 2. Iliacus 3. Pectineus 4. Adductor Longus/Brevis 5. Gluteus Minimus 6. Gluteus Medius 7. Piriformis 8. Obturator Externus ⠀ These muscles (with Obturator internus and gemelli) work as a team to stabilize the femur and the pelvis so the larger muscles can produce torque (glute max, hamstrings, quads). If one “arrow” pulls more or less than the others, a potential disruption in joint centration ensues, directing forces in unnatural directions and stressing the joint surfaces. ⠀ Balanced tissue tension → joint centration → optimal hip function. ⠀ Know your functional anatomy, not just what the books say. It will make you a better doctor, therapist or coach. ⠀ Picture credit: @anatomylinks #anatomy #biomechanics #functionalanatomy #doc #tensegrity #anatomia #chiropractic #osteopathy #physicaltherapy #physiotherapy #acupuncture #dryneedling #hip #muscles #fascia #yoga #joints #yogaanatomy #squats #function #triggerpoint #physiology #pilates #medicine #crossfit #human #fascia #therapy #doctor #training #stability https://www.instagram.com/p/CRQ8XI7Ax_C/?utm_medium=tumblr

CORACOID TENSEGRITY [FUNCTIONAL ANATOMY & BIOMECHANICS] The coracoid process of the scapula is an anchor point for a number of muscles and ligaments. These soft tissues all provide a certain amount of tension in their own specific vector to balance the forces on the coracoid process. These structures also have a role in stabilizing the forces on their other attachments. The tissues include muscles: 1. Biceps brachii short head 2. Coracobrachialis 3. Pectoralis Minor Ligaments: 4. Conoid ligament 5. Trapezoid ligament 6. Coraco-glenoid ligament (posterior to coracoid, not visible) 7. Coraco-acromial ligament posterior 8. Coraco-acromial ligament anterior 9. Coraco-humeral ligament anterior band 10. Coraco-humeral ligament posterior band The coraco-clavicular ligaments (conoid, trapezoid) resist superior translation of the clavicle with the conoid also resisting anterior translation and the trapezoid resisting posterior translation of the clavicle. The coraco-acromial ligaments manage the space between the coracoid and the acromion which houses the subacromial bursa (star). The bursa is cradled inferiority by the coraco-humeral ligament. If the tensional balance on all of these tissues is disturbed from injury, fibrosis or spasm, the net result is a disturbed position of the clavicle, scapula and humerus along with alteration of all spaces between the bones. This will also lead to common biomechanical dysfunctions such as “subacromial impingement” of the subacromial bursa and supraspinatus tendon. While most focus on the rotator cuff in rehabilitating impingement syndromes, one can’t forget the coracoid complex and it’s role in shoulder girdle function. Conceptualizing where the structures are located and then precisely palpating them will be the only way to effectively treat these important tissues.

FOOT TENSEGRITY ⠀ [FUNCTIONAL ANATOMY & BIOMECHANICS] ⠀ The bones of the body are not totally solid objects like stone columns. They are, however, similar to reinforced concrete in their internal design. Like all tissues in the body, the bones are made of specialized fascia with the outer layering being periosteum and the interior being effectively hollow. ⠀ What gives the bones their strong compression resistant qualities is the architecture of the interior. Specifically, the varying lines of forces in gravity create interlocking lines of micro bone formation called trabeculae. ⠀ The trabecular system is similar to the idea of iron rebar rods that are threaded through concrete to give it greater stability. These lines of the trabecular system match common lines of force in the body and link other bones together to make joints. ⠀ The picture of the foot shows the force of the body’s weight (100%) going down from the tibia and into the talus. You can see the forces follow the trabecular lines the whole way through the metatarsals and into the toes, allowing force to flow joint to joint, bone to bone. This force is then returned via ground reaction force through the same “train tracks”. But much like train tracks, they only allow the train (force is the train in this case) to move along them if they link together in line. ⠀ This validates the ideas of “proper joint alignment” or centration in treatment or training. If a person has an anterior position of the talus from a previous ankle sprain, their trabecular system is no longer as stable and the soft tissues need to undertake more of the force to keep the joints stable (tensegrity). ⠀ Force transmission is compromised making movement less efficient when trabecular lines aren’t connected. Tensegrity is about the balance between compression elements and tension elements. The trabecular system supplies the compression support, deloading soft tissues such as cartilage and ligaments. ⠀ The foot is the boss of the kinetic chain!🦶 ⠀ Credit: @anatomylinks #anatomy #biomechanics #functionalanatomy #doc #tensegrity #anatomia #chiropractic #osteopathy #physicaltherapy #physiotherapy #acupuncture #dryneedling #hip #muscles (hier: Germany) https://www.instagram.com/p/CE_pH8lBbW6/?igshid=2rn533kjbeum

QUADRATUS PLANTAE MUSCLE PAIN ⠀ [PATHOLOGY AND SELF-TREATMENT] ⠀ The quadratus plantae (QP) is a muscle in the foot that extends from the anterior (front) of the calcaneus (heel bone) to the tendons of the flexor digitorum longus muscle in the leg. It assists the flexor digitorum longus with toe flexing. The muscle brings the pulley of the flexor digitorum longus in line with the length of the foot. The QP muscle also increases stability of the foot by resisting extension of the toes. For more information about this muscle check my previous posts! ⠀ When the muscle is not functioning properly - is tense or carries trigger points (TP’s) - it can be a cause of heel pain and claw toe deformity. Diabetic polyneuropathy (a type of nerve damage that may occur as a complication of diabetes) may cause pain and tingling in the muscle. ⠀ Tensions in the QP muscle often lead to foot pain and local sensitivity to pressure. TP“s can trigger pain in the area of the heel as you can see in the red marked zones on picture 1. ⠀ Self-massage of the QP muscle with a @Blackroll Ball 08: ▪️Place the Blackroll Ball under your foot in sitting or standing position. ▪️Now roll the ball in the area of the QP (plantar midfoot), use the weight of your leg for pressure. ▪️Execute short and slow movements over the entire length of the muscle and look for painful tensions & TP’s. ▪️Once you find one, move a few times from just before to just behind the painful spot until you feel it eases in the tissue. ⠀ Check and subscribe my YouTube channel for more information about treatment and exercises: www.youtube.com/stefanduell ⠀ #anatomy #flatfeet #footpain #foot #fascia #soccer #biomechanics #biotensegrity #running #football #functionalanatomy #functionalrehab #sprint #yoga #bigtoe #turftoe #bunion #chiropractic #massage #physicaltherapy #acupuncture #dryneedling #arch #yogaanatomy #strongfeet #tensegrity #footarch #physiotherapy #osteopathy #sport https://www.instagram.com/p/B_pSZ7HpUO6/?igshid=q4auh3wo8f1w

MUSCLES IN THE ANTERIOR COMPARTMENT OF THE LEG - PART 2 ⠀ [CADAVER DISSECTION ANATOMY] ⠀ There are four muscles in the anterior compartment of the leg; tibialis anterior, extensor digitorum longus, extensor hallucis longus and fibularis tertius. Collectively, they act to dorsiflex and invert the foot at the ankle joint. The extensor digitorum longus and extensor hallucis longus also extend the toes. The muscles in this compartment are innervated by the deep fibular nerve (L4-S1), and blood is supplied via the anterior tibial artery. ⠀ In this post we will focus on extensor hallucis longus and fibularis tertius. ⠀ Extensor Hallucis Longus (Video 1-3) The extensor hallucis longus is located deep to the EDL and TA. It originates from the medial surface of the fibular shaft.  The tendon crosses anterior to the ankle joint and attaches to the base of the distal phalanx of the great toe. Actions: Extension of the great toe & foot dorsiflexion. ⠀ Fibularis Tertius (Video 4,5) The fibularis tertius muscles arises from the most inferior part of the EDL. It is not present in all individuals, and is considered by some texts as a part of the extensor digitorum longus. Because one part of the EDL attaches onto the 5th metatarsal and not an actual toe („digit“), it is renamed as a separate muscle. The third fibularis muscle, in other words, fibularis tertius. It originates with the extensor digitorum longus from the medial surface of the fibula. The tendon descends with the EDL, until they reach the dorsal surface of the foot. The fibularis tertius tendon then diverges and attaches to metatarsal V. Actions: Foot eversion & dorsiflexion. ⠀ #anatomy #biomechanics #functionalanatomy #doc #tensegrity #anatomia #chiropractic #osteopathy #physicaltherapy #physiotherapy #acupuncture #dryneedling #hip #muscles #fascia #yoga #joints #yogaanatomy #squats #function #triggerpoint #physiology #pilates #medicine #crossfit #human #sport #therapy #doctor #training (hier: Los Angeles, California) https://www.instagram.com/p/B9kDI1Wh54N/?igshid=1dwstsgnwh74f
