Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.
Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”

Bone scans are used to detect and monitor infection, fracture, or disorders in the bone. A small amount of radioactive material is injected into the bloodstream and will collect in the bones, particularly in areas with some abnormality. Scanner-generated images can be used to identify specific areas of irregular bone metabolism or abnormal blood flow, as well as to measure levels of joint disease.

These exercises can be done three to five times per week; be sure to build in a rest day here or there to allow your hip muscles to recover. Working to strengthen your knees and ankles can be done as well to be sure you completely work all muscles groups of your lower extremities. Remember, your ankle and knee muscles help control the position of your hips, just as your hip muscles control the position of your knees and ankles. They all work together in a kinetic chain.

Vertebroplasty and kyphoplasty are minimally invasive treatments to repair compression fractures of the vertebrae caused by osteoporosis. Vertebroplasty uses three-dimensional imaging to assist in guiding a fine needle through the skin into the vertebral body, the largest part of the vertebrae. A glue-like bone cement is then injected into the vertebral body space, which quickly hardens to stabilize and strengthen the bone and provide pain relief. In kyphoplasty, prior to injecting the bone cement, a special balloon is inserted and gently inflated to restore height to the vertebral structure and reduce spinal deformity.
