The gluteus medius is a particularly important muscle that we have not paid much attention to in the past for hip protection and strengthening. Professor Ganz, an orthopaedic master from Switzerland, came to China to give lectures, repeatedly emphasizing the primary role of the gluteus medius in hip protection and hip health, and teaching himself the secrets of training the gluteus medius. The gluteus medius is the most important muscle to maintain the stability of the pelvis and normal posture for hip health and protection. If the gluteus medius is trained well, the walking posture will be normal, but if it is not trained well, the walking posture will be abnormal, for those who do not have hip problems, but even more so for those who have hip problems, especially those who have undergone surgery. If the gluteus medius is abnormal, you will walk like a duck, swaying and wobbling. Where is the gluteus medius muscle located in our body? Look at these two anatomical diagrams above. The gluteus maximus is located behind the hip joint and is mainly responsible for the extension of the hip joint. The gluteus medius is located on the outside of the hip joint, and its posterior half is located below the gluteus maximus, like a fan, hence the name pectus carinatum. The medical terminology describes it as: the gluteus medius is located outside the iliac wing. The posterior portion of the gluteus medius is located deep in the gluteus maximus muscle and ends at the greater trochanter of the femur. The main function of the gluteus medius is to abduct the thigh during pelvic fixation; the anterior part of the gluteus medius is to flex and internally rotate the thigh; the posterior part of the gluteus medius is to posteriorly extend and externally rotate the thigh; the middle part of the gluteus medius is also the most important part of the gluteus medius, and its role is to abduct the thigh while stabilizing the pelvis and hip joint. The gluteus medius is an important muscle for maintaining good posture when we walk and stand in our daily lives. When we walk, the gluteus medius keeps the trunk straight and the hips relatively fixed. The gluteus medius plays a strong role in stabilizing the pelvis during forward strides. When we stand, it can stabilize the pelvis and then the trunk. The gluteus medius plays an extremely important role in our daily life trunk activities, such as bending, standing upright, walking, squatting, etc. The gluteus medius is very susceptible to strain. When we suddenly change our position, the gluteus medius is more likely to be injured. The clinical manifestation is soreness of the hip, which is painful late at night, in the morning and during activities, and is aggravated by exertion and shade. 50% of patients feel diffuse pain in the thigh, which often manifests as chronic attacks. On physical examination, the doctor may find pressure points in the gluteus medius muscle, and there may be painful tendon bundles, and the pressure points may be one or more, and pressure points may appear in the anterior, middle and posterior parts of the gluteus medius muscle. Local and diffuse area pain may appear when pressing on the painful points, and hip and thigh pain may appear on the side of hip disorder when straight leg elevation is performed. When an orthopedic surgeon performs any kind of hip surgery, the gluteus medius muscle is easily disturbed or stimulated due to the surgical incision and intraoperative pulling, thus causing postoperative changes in the strength of the gluteus medius muscle and even a state of gluteus medius weakness. Therefore, it is necessary to train the gluteus medius before and after any kind of hip surgery. In order to protect the hip, regardless of whether there is a hip disorder or not, and for the sake of our healthy life, everyone should train the gluteus medius: standing position training gluteus medius: standing before surgery without holding an abductor, standing after surgery with a double abductor. Stand on one leg, raise the affected leg laterally by 20° to 30°, pause for 10 seconds after the lateral raise, retract to a double-legged standing position, raise laterally again and pause for 10 seconds. Progressively until you do 30 each time. Lateral position training gluteus medius: lie on the sofa or bed on your side, tilt your upper body forward by 10°, put a small pillow on your lower back to keep your pelvis in a standard lateral position, straighten your legs, raise the affected leg laterally by 20° to 30°, pause for 10 seconds when raising it and then retract it to present your legs in a straight position, pause for 10 seconds when raising it again. Gradually until you do 30 at a time. If both hips are affected, you can rotate the left and right gluteus medius. If the affected hip is unilateral, you can also rotate between the healthy side and the affected side. Even for healthy people without hip problems, learning the secrets of gluteus medius training will benefit them for life.
