FIBULA TENSEGRITY ⠀ [FUNCTIONAL ANATOMY & BIOMECHANICS] ⠀ The fibula is called a floating bone that is not directly weight bearing but has huge contribution to the locomotor system. It works with its neighboring tibia to create an important tensegrity relationship that allows for progression in the gait cycle. ⠀ During the gait cycle, bodyweight is transferred from leg to leg and this transfer of energy is initially enabled by the pronation phase of the lower extremity. Upon heel strike, the friction of the calcaneus on the ground begins a chain reaction of joint dynamics. The downward force of the bodyweight pushes the fibula inferior and laterally, while the tibia is also pushed into the ground and medially. This widens the syndesmosis of the ankle, making space for the talus to slide relatively posterior in the ankle mortise and creating ankle dorsiflexion. ⠀ As in other tensegrity relationships, the tension balances the compression and builds in the soft tissues such as the interosseous membrane (light blue), anterior superior tib-fib ligament (green), Barkow ligament (dark blue) and anterior inferior tib-fib ligament (purple). These soft tissues help convert the downward compressive forces from the bodyweight into tension forces and stored potential energy as they’re stretched. ⠀ This stored energy is then released “up the chain” into the superior joints helping efficiently complete the gait cycle (see C. Weinhart study in Developmental Dynamics for more). ⠀ One can imagine the ill-effects of a lateral ankle sprain or a tib-fib joint fixation and it’s disruption of these fibular mechanics and subsequent total system stress. Back pain is often linked to ankle function. Keep all the soft tissues hydrated and elastic to maintain efficiency in locomotion. ⠀ Credit: @anatomylinks #anatomy #fascia #tensegrity #biomechanics #foot #softtissue #ankle #anklesprain #chiropractic #knee #physicaltherapy #physiotherapy #massage #yoga #running #yogaanatomy #physiology #inversiontrauma #supinationtrauma #osteopathy #orthopedics #knowledge #medicine #doctor #medstudent #student #biotensegrity #manualtherapy #kneepain #footpain (hier: Germany) https://www.instagram.com/p/CE6GiMBh61C/?igshid=1tqpmgx3v1s27
