The Hip
Compared to such complex areas of the body as the back and knee, the hip region is straightforward and sturdy. It takes great force to cause hip injuries. In addition, the large, strong muscles of the thighs and buttocks - which help support and move the hips and knees - are usually able to withstand an enormous amount of abuse.
However, sports-related injuries and problems do occur - particularly in female runners - and there are also problems specific to young men and pregnant women. The elderly are subject to the most serious problems - life-threatening hip fractures that are often due to osteoporosis.
Though not as common as in other areas of the body, the muscles and tendons of the hip and groin region are subject to wear and tear and overuse injuries – leading to hip pain. The usual causes of muscle strain and tendinitis are inadequate warm-up and stretching before physical activity or a burst of exercise after being sedentary.
