Hip Problems, Age 11 and Younger - Topic Overview
A hip problem can be hard to deal with, both for the child who has the problem and to the parent or caregiver. A child who has a hip problem may feel pain in the hip, groin, thigh, or knee. A child in pain may limp or be unable or unwilling to stand, walk, or move the affected leg. A baby in pain may cry, be fussy, and have other signs of pain. Hip problems may be present at birth (congenital) or may develop from injury, overuse, inflammation, infection, or tumor growth.
To better understand hip problems, it may be helpful to know how the hip works. It is the largest ball-and-socket joint in the body. The thighbone (femur) fits tightly into a cup-shaped socket (acetabulum) in the pelvis. The hip joint is tighter and more stable than the shoulder joint but it does not move as freely. The hip joint is held together by muscles in the buttock, groin, and spine; tendons; ligaments; and a joint capsule. Several fluid-filled sacs (bursae) cushion and lubricate the hip joint and let the tendons and muscles glide and move smoothly. The largest nerve in the body (sciatic nerve) passes through the pelvis into the leg.
Hip problems may develop from overuse, infection, or a problem that was present from birth (congenital). Oddly enough, a child who has a hip problem often feels pain in the knee or thigh instead of the hip. Hip problems that affect children include:
