Introduction
Hip fractures are surgically repaired with a special type of metal plate and
screw, called a compression screw, for a couple of reasons. First, it helps
align the bone fragments and hold them in the proper position. Second, the
fixation device is strong enough to keep the bones in place as you begin to move
about. Before these devices were used, a patient needed to remain in bed usually
with traction to hold the bones in alignment. The fixation now holds the bones
in place while the bone heals. This allows you to get out of bed sooner because
the metal plate and screw are strong enough to hold the bone fragments in place
as you move.
The procedure requires a small incision on the side of the hip, and the plate
and screw usually provide a solid connection for the broken bones. Since
patients are able to get moving right away after surgery, they are more likely
to avoid the serious complications that can arise with being immobilized in
bed.
Surgical Procedure
Compression hip screw fixation can be an involved surgery with several
fragments of bone needing to be held together. There may also be substantial
blood loss during surgery, which could require you to have a blood transfusion
during the operation.
This operation can be done using either a general anesthetic or a spinal
block. A general anesthetic puts you completely to sleep. A spinal block puts
your body to sleep only from the waist down. The anesthesiologist will also give
you medications so that you won't be aware the operation is being done.
Once you have anesthesia, your surgeon will make sure the skin of your hip is
free of infection by cleaning the skin with a germ-killing solution.
With the patient lying flat on a special table, the foot and leg are
supported and the fractured bones are lined up. The surgeon checks the alignment
using a fluoroscope, a type of X-ray machine that shows the image on a TV
screen.
Next, the surgeon makes an incision over the side of the thigh. A large metal
screw is placed through the side of the hip into the top of the thighbone
(femoral head). With the help of the fluoroscope, the surgeon attaches a metal
plate to the side of the thighbone (femur) with four to eight small metal
screws. The procedure can usually be finished in less than an hour depending on
how many fragments of bone are involved in the fracture.
The soft tissues are put back in place, and metal staples or sutures are used
to close the incision.
Complications
Common complications after a hip fracture are sometimes the result of being
immobilized in bed. These may include pneumonia, bedsores, mental confusion, and
blood clots (deep vein thrombosis).
Complications that can result from the compression fixation surgery itself
include infection, nerve or blood vessel injury, or nonunion of the bones.
This is not intended to be a complete list of possible complications.
After Surgery
Your hip will be covered with a padded dressing. If your doctor used a
general anesthesia, a nurse or respiratory therapist will guide you in a series
of breathing exercises. You'll use an incentive spirometer, a breathing
exerciser to help improve your breathing and avoid possible problems with
pneumonia.
A physical therapist will direct your recovery after surgery. You'll be
encouraged to move from your hospital bed to a chair several times the first day
after surgery. You'll be encouraged to begin getting up and walking with your
crutches or walker, but you may need to avoid placing too much weight on your
foot while you stand or walk. You'll be ready to go home when you can move about
safely with your walker or crutches, are able to do your exercises, and your
caregiver has made all the necessary preparations for you at home.
Rehabilitation
Home Health Needs
Once discharged from the hospital, you may see a therapist for one to six
in-home treatments. This will help to ensure your safety in and about the home
and getting in and out of a car. Your therapist will make recommendations about
your safety, review an exercise program, and continue working with you on
walking and strength. In some cases, additional visits at home may be required
before beginning outpatient physical therapy.
Outpatient Physical Therapy
Additional outpatient physical therapy visits are sometimes needed for
patients who are still having problems walking or who need to get back to
physically heavy work or activities.
A therapist may use hands-on stretches for improving range of motion.
Strength exercises address key muscle groups including the buttocks, hips, and
thighs.
Therapists sometimes treat their patients in a pool. Exercising in a swimming
pool puts less stress on the hip joint, and the buoyancy makes movement and
exercise easier. An independent program may be assigned once the therapist has
taught you come pool exercises.
When it is safe to putt full weight through the leg, several types of balance
exercises can be chosen to further stabilize and control the hip. Finally, a
select group of exercises can be used to simulate day-to-day activities, such as
going up and down steps, squatting, and walking on uneven terrain. Specific
exercises may then be chosen to simulate work or hobby demands.
The therapist's goal is to help patients maximize hip range of motion and
strength, restore a normal walking pattern, and safely participate in certain
activities. When patients are well underway, regular visits to the therapist's
office will end.
