All About Your Hip Joints

Most of us think about our “hips” as the entire pelvic area—front, back, and sides. For example, when we take our hip measurements to determine our pants size, we put the tape measure all around the widest part of pelvis. But when medical professionals talk about hip problems or breaking a hip, they are typically referring to the hip joint itself, where your pelvis connects to your thighbone. Here is an illustration:Like your shoulder joint (see All About Your Shoulders), your hip joint allows a large range of motion. It is a joint is a synovial joint, which means it connects your pelvic bone and thighbone (femur) together with a joint capsule (a sock-like sleeve of connective tissue that holds the two bones relatively close together). The inner lining of this capsule is lined with synovial membrane, which secretes a lubricating liquid that allows the bones to move over each other more smoothly. Think about that the next time you’re moving in and out of a yoga standing pose or even just walking down the street. (For more on the anatomy of the hip joint, see Arthritis of the Hip Joint.) Here’s a list of all the movements you can make from your hip joints!
1. Flexion: This means moving your leg in toward the front of your lower torso or bringing the front of your lower torso toward your leg (a forward bend in your hips). For example, lifting your leg up in Standing Hand to Foot pose (Hasta Padangustasana) or Reclined Standing Hand to Foot pose (Supta Padangusthasana), stepping one leg forward and bending that knee as in Warrior 1 (Virabrdrasana 1) or tipping the hips forward over the leg Pyramid pose (Pasvottanasana). 
2. Extension: This means moving your leg back toward the back of your lower torso or bringing the back of your lower torso toward your leg (a backbend in your hips). For example, when you step your back leg back into Warrior 1 or lift your legs up in Locust pose (Salabasana). 
3. Abduction: This means moving your leg to the side, away from the midline of your body. For example, when you step both legs out to the sides from Mountain pose (Tadasana) into the wide-leg stance for a standing pose such as Triangle pose (Trikonasana).
4. Adduction: This means moving one leg across the other, as in Eagle pose (Garudasana), or moving a leg that was out to the side back toward the midline of the body, such as stepping back into Mountain pose from a wide-leg stance. 
5. External Rotation: This means turning your leg out within your hip socket so the leg turns away from the midline of your body. For example, when setting up your front foot position for Triangle pose, you externally rotate your front leg as you turn your front foot out to 90 degrees before entering the full pose. This movement is almost always combined with one or more of the others listed above.
6. Internal Rotation: This means turning your leg in within your hip socket so the leg turns toward the midline of your body. For example, when you are setting up your back foot position for Triangle pose, you internally rotate your back leg as your turn your back foot slightly inward. This movement is almost always combined with one or more of the others listed above.
As with the shoulder joint, the hip joint structure that provides so much range of motion also creates certain vulnerabilities. For example, arthritis of the hip joint is a particularly common in those who are aging. So, keeping your hips happy and healthy should be a regular component of your yoga for healthy aging practice. Generally, this means practicing both stretching and strengthening the muscles around the hip joint, unless you are someone who is hypermobile, in which case, you should focus just on strengthening.
Here’s the information we have on the blog that help you figure out how to practice whether your hip joints are currently healthy or you are having a problem with them.
