A typical ankle sprain occurs when a patient steps onto an uneven surface and falls, causing injury to the supportive ligaments of the ankle. This causes instability of the ankle joint. Along the outside regions of the ankle, the supporting ligaments can become stretched or torn (partially or completely). Injuries to the ankle joint is one of the most common in the body. The inside region of the ankle is the medial malleolus. This bone is specifically the bottom, outside portion of the Fibula. The bone that sticks out along the outside of the ankle is the lateral malleolus. What is the Bone that sticks out on the side of your Ankle? They contribute to your ability to walk, push off, and/or pivot to change directions. These work together to allow for movement of the ankle and ankle. Many bones come together to form the various joints of the ankle/foot complex.
The 2 cuneiform bones (lateral and middle) join the calcaneus to form the Calcaneocuboid joint. The two bones, the Cuboid, and Navicular bones, then join 3 smaller bones of the Cuneiform (lateral, middle, and medial). Similarly, the calcaneus joins the outer region of the foot at the Cuboid bone to form the Calcaneocuboid joint. Moving forward, towards the top and inside regions of the foot, the Talus joins together to form the Talonavicular joint at the Navicular bone. This region where the Talus and the Calcaneus come together creates the Subtalar joint. Along the bottom aspect of the Talus, this bone sits on the top of the Calcaneus or heel of the foot. These two bottom portions of the lower leg bones sit on top of the Talus, which form the tibiotalar joint. Involving about 7 major bones, the bones in the ankle are the bottom portions of the 2 lower leg bones the Tibia and Fibula. The ankle joint is located above the foot, where the lower leg and the top of the foot come together. In the shoulder, it is common to develop rotator cuff tendinitis, which is a swelling of the tendons that support the rotator cuff.By Bridget Bigale, PTA What are the 7 Bones in the Ankle? Osteoarthritis is a common problem seen in the hip joints that occurs as the lubricating cartilage of the joint degenerates. Common ball and socket joints include the hips and shoulders. Since the rounded head can move freely within the cup, or socket, this allows for movement in all directions. There are six different types of synovial joints, including: Ball and Socket Jointsīall and socket joints are composed of one bone with a rounded head that fits into the cup of another bone. For this reason, we will be looking closely at the different types of synovial joints, where they are found in the body, and what problems or injuries commonly affect them.
When it comes to joint problems and injuries, synovial joints are affected far more than fixed or cartilaginous joints. Synovial joints are the most common joint in the body and are the type of joint that most people are familiar with. Diarthroses (freely movable), also known as synovial joints, are defined as containing synovial fluid that allows for all parts of the joint to move against each other.An example of cartilaginous joints are the vertebrae. Amphiarthrosis (slightly movable joints), also known as cartilaginous joints, are defined as two or more bones held together so tightly that movement is limited.An example of immovable joints are the plates of the skull. Synarthroses (immovable joints), also known as fixed or fibrous joints, are defined as two or more bones in close proximity that have no movement.Joints in the human body are defined by their movement (or absence of movement). Did you know that there are between 250-350 joints in the human body? The reason why this is not an exact number is because the number of joints can vary with age, the number of sesamoids can vary, and the definition of joints can either be the point at which two bones connect or the point where bones connect for the purpose of movement.
