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 buttocks, 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
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.
A
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
clumsy walk.
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
socket.
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
surgery.
Review the Emergencies and Check Your Symptoms sections
to determine if and when your child needs to see a health professional.
Check Your Symptoms
If you answer yes to any of the following questions, click on the "Yes" in front of the question for information about how soon to see a health professional.
Review
health risks that may increase the seriousness of your
child's hip symptoms.
If your child has any of the
following symptoms, evaluate those symptoms first.
You may wait to see if your child's symptoms improve over the next 24 hours (or specified time period) if you answer "Yes" to
any of the following questions.
Does your baby have extra skin folds on the inner side of one thigh
compared with the other thigh so the skin folds do not look like the same
pattern on each thigh?
If you have answered "No" to the above questions, go back to Check Your Symptoms and continue to answer the questions to evaluate your symptoms.
If a visit to a health professional is not needed immediately, see the Home Treatment section for self-care information.
Home Treatment
Home treatment may help relieve your
child's hip pain, swelling, and stiffness. If your child will cooperate, use
the following tips. If your child becomes upset or will not cooperate, do not
force your child.
Rest. Have your child rest and protect the sore
hip. Have your child stop, change, or take a break from any activity that may
be causing pain or soreness.
Ice will help your child's pain and
swelling. Put
ice or cold packs on the sore area immediately. Put ice on for 20 minutes
out of every hour and do this 4 or more times in the first 1 to 2 days. If your
child is cooperative, use the ice often. If your child is not cooperative, use
the ice as much as you can without struggling with your child. Wrap the ice in
a wet towel. Do not put the ice right on the skin. Take the ice off if your
child falls asleep.
Put your child on the side that does not have a
problem for sleep.
Gently rub your child's hip to relieve pain and
help blood flow.
If the swelling is gone,
heat can be put on the area. Your child can carefully
begin normal activities. Moist heat with a hot water bottle, warm towel, or a
heating pad set on low may feel good to your child.
Medicine you can buy without a prescription
Try a nonprescription
medicine to help treat your child's fever or pain:
Talk to your child's doctor before switching back and
forth between doses of acetaminophen and ibuprofen. When you switch between two
medicines, there is a chance your child will get too much medicine.
Safety tips
Be sure to follow
these safety tips when you use a nonprescription medicine:
Carefully read and follow all labels on
the medicine bottle and box.
Give, but do not exceed, the maximum
recommended doses.
Do not give your child a medicine if he or she
has had an
allergic reaction to it in the past.
Most of the problems that can affect a
child's hips or cause a child to limp cannot be prevented. The following tips
can help keep your child's bones healthy and strong.
Keep bones strong
Have your child eat a nutritious diet with
enough
calcium and
vitamin D, which helps his or her body absorb calcium.
Calcium is found in dairy products, such as milk, cheese, and yogurt; dark
green, leafy vegetables, such as broccoli; and other foods.
Have
your child stay active. Play and sports are good ways for your child to
exercise.
Do not give your child caffeine, such as in soda pop.
This may increase calcium loss from his or her body.
You can help your health
professional diagnose and treat your child's condition by being prepared to
answer the following questions:
What are your child's main symptoms? How long
has your child had symptoms?
Has your child had this problem in the
past? If so, do you know what caused the problem at that time? How was it
treated?
Does your child limp or complain about pain when he or she
walks? Where is the pain felt? How far can your child walk without pain? Does
the pain get better or worse as he or she continues to walk?
Has
your child had any recent illness or fever?
What activities make
your child's symptoms better or worse?
What activities does your
child do? Has your child recently started a new activity?
What home
treatment measures have you tried? Did they help?
What prescription
or nonprescription medicines has your child taken? Did they
help?
Does your child have any
health risks that may increase the seriousness of his
or her hip symptoms?
