The ankle joint consists of three bones: the fibula, tibia and scree. The first two form a dome that fits the top of the third. It includes, in particular, the forward and backward rotation movements, which are flexion and extension movements of the foot. In the lateral direction of the foot of the fibular ankle and the medial ankle, which are two bone appendages, continue to immobilize the fibula and tibia on both sides, which prevents the movement of full lateral rotation, but allows it to start.
The talis rests on the calcaneus, forming an articular rather flat, without much movement. The subtalar joint is a source of conflict and supports the transfer of forces to the weight of the control body and the subtle movements of the stability of the foot. When cartilage degrades this compound, arthritic degeneration and pain occur, which sometimes requires surgery to suppress or treat.
Interestingly, given their importance in the production of sports injuries, an attachment or a tail in scree. On foot, twitching backwards, like a place to strike to force a ball, the highlight of the bones switched, collided with the back of the tibia and broke. The fracture is sometimes tolerable, but others require surgery, removal of the broken one, so that the athlete can continue to hit the ball without pain. It should not be confused with the anatomical variant, the ozone triggered scree, which offers an X-ray image of a friable scree, often indistinguishable from a fracture.
The talis expresses, following the direction leading to the fingers, with a rook and a cuboid, located in the area inside and outside the leg, respectively. There are three spots between the pinniped and the line formed by metatarsals. Metatarsals are almost flat bases and a spherical head for articulation with the first finger joints.
Ankle ligaments
The joint connection is necessary to maintain the adhesion of the bones, which are formed, preventing its displacement, dislocation and allowing other movements of your hand. The description of all ligaments of the ankle and foot will be highly specialized due to their number and complexity.
The joint capsule surrounds the joint, creating an enclosed space and helps the connections in the stabilizer of its mission.
- External lateral ligament. Starting from the tip of the external ankle, it is divided into three parts (fibular posterior talar, calcaneal fibular and anterior talaric fibular) that holds the ankle. If they break, it is easy to catch the ankle in the movements of the foot attachment.
- Deltoid ligament. In contrast, it is a ligament of the medial ankle and the ankle inside the ankle.
- syndemic ligament, syndesmosis or tibiophilar ligament. Tie the distal part of the tibia and fibula to hold them together in the role that claims to the articular surface of the dome talus. His failure causes many problems. Healing takes a long time and can leave the permanent effects of pain and instability requiring surgical intervention. The ligament connects the two bones to the very end of their junction, and not just in front of the ankle. Therefore, when it breaks, you can leave a hanging fringe joint and pain in the back of the ankle.
- In the back of the ankle there is also a network of ligaments connecting the tibial bone and the fibular (posterior tibiofecular), tibia and scree, etc. We must emphasize the transverse ligament, which is damaged by the same syndemosis mechanism, which can be considered further expansion.
Muscle
The external muscles of the foot are responsible for the movement of the ankle and foot. Despite the fact that they are in the leg, training their traction pulls bony inserts of the ankle and foot. Control the movement of dorsiflexia, plantar flexion, nesting and foot elimination.
- The internal muscles of the legs - those that are located on the same support, receive finger movements: flexion, stretching, abduction and adduction.
- Plantar flexors. These are the ones that pull the leg back. Thus, they are located in the rear of the calf's legs. They are the soles and twins with the Achilles tendon, which is common to both.
- Spinal flexors are those that raise the leg and are located in front of the leg. These are the anterior part of tibialis, the perineal tertius, and the dic ticum extensor.
- Investor. Front tibial inserts in the first metatarsal and first wedge.
- Evertor leg. The pernual long and intermediate brevi is inserted into the first cuneiform and first metatarsal base, while the front peroneal is inserted into the bases of the fourth and fifth.
“The plantar fascia is a structure that should be born anatomically in mind, because when it is inflamed, a terrible plantar fasciitis occurs, very disturbing and disabling. This is the structure that forms the floor of the plantar arch and is inserted into the lower part of the calcaneus.
