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:
An inflammatory reaction, such as
transient or toxic synovitis. This generally occurs
after the child has had a cold or other upper respiratory infection. This is
the most common cause of hip pain in children.
slipped capital femoral epiphysis. This occurs when
the upper end of the thighbone (head of the femur) slips at the growth plate
(epiphysis) and does not fit in the hip socket correctly.
An inward twisting of
the thighbone (femoral anteversion). This condition causes the knees and feet
to turn inward. The child will have a "pigeon-toed" appearance and may have a
Developmental dysplasia of the hip (DDH). This condition is caused by a problem in the development of the
hip joint. The top of the femur does not fit correctly into the hip socket
(acetabulum) so the femur can partially or completely slip out of the
In rare cases, cancer of
the bone, such as osteosarcoma.
Treatment for a hip problem depends on the location, type,
and severity of the problem as well as the child's age, general health, and
activity level. Treatment may include first aid measures; application of a
brace, cast, harness, or traction; physical therapy; medicines; or
Severe pain (8 to 10): The pain
is so bad that the child can't stand it for more than a few hours, can't sleep,
and can't do anything else except focus on the pain. No one can tolerate severe
pain for more than a few hours.
Moderate pain (5 to 7): The pain is bad enough to disrupt the child's normal activities and
sleep, but the child can tolerate it for hours or days.
Mild pain (1 to 4): The child notices and may complain of the pain,
but it is not bad enough to disrupt his or her sleep or activities.
Symptoms of infection may
Increased pain, swelling, warmth, or redness in or
around the area.
Red streaks leading from the area.
Pus draining from the area.

Severe pain (8 to 10): The

constantly no matter what you do. The baby may kick, make fists, or
Moderate pain (5 to 7): The baby is
very fussy, clings to you a lot, and may have trouble sleeping but responds
when you try to comfort him or her.
Mild pain (1 to 4): The baby is a little fussy and clings to you a little but responds
when you try to comfort him or her.
