Heel Fat Pad Syndrome
(HFPS) refers to damage or
disruption of the fatty pad that sits under our heel bone (calcaneous). This structure is approximately one inch
thick and is made up of fatty tissue enclosed by ligamentous chambers. The purpose of this structure is to absorb
shock and cushion the heel bone. If the
fat pad is displaced or thins, then its ability to protect the heel bone from
impact is decreased, which can result in heel pain.
HFPS is
commonly misdiagnosed as plantar fasciitis.
Plantar fasciitis symptoms tend to be located towards the inner front
portion of the heel and can extend into the arch of the foot, whereas symptoms
of HFPS are characteristically located
in the centre of the heel and described as a deep, dull ache that feels like a
bruise. Other symptoms characteristic of
HFPS include central heel pain that
is aggravated by prolonged periods of standing and barefoot walking on hard
surfaces. It is also possible to have both
plantar fasciitis and HFPS present
at the same time.
There
are several factors that can contribute to the development of HFPS.
Trauma to the heel from high impact sports or a forceful blow to the
heel from a fall can cause injury to the fat pad. Repetitious chronic overload from activities
such as running, jumping or prolonged walking and standing can also cause
injury which can be exacerbated by the use of improper footwear. It is known that the fatty heel pad breaks
down as we get older which can make an individual susceptible to this
condition. Carrying extra pounds can
also break down the protective fatty tissue under the heel bone.
Self-care strategies
for reducing the pain of HFPS
include: relative rest from any painful activities; ice application; and gentle
stretching of the achilles tendon, and calf muscles. Gel or “donut pads” placed under the affected
heel(s) in shoes may also provide relief.
Long-term strategies may include activity modification and weight loss
where applicable.
HFPS that does
not respond to self-care strategies may require professional treatment. This can include electrotherapeutic
modalities to assist in healing, manual and soft tissue therapy to supporting
structures, therapeutic taping of the heel, and specific rehabilitative exercises for the muscles and joints of the
lower leg and foot. Supporting the foot
with proper footwear and correcting faulty foot mechanics can decrease
excessive strain on the fat pad. A
custom made orthotic with a deep heel cup design to cradle and cushion the fat
pad may also be helpful for decreasing symptoms.
It is important to
establish an accurate diagnosis of HFPS. Other causes of heel pain may include stress
fractures, achilles tendonitis/bursitis, arthritis, gout, or nerve irritation. If you are having difficulty with heel pain,
a qualified health professional can determine the cause of your pain and
prescribe appropriate therapy and rehabilitation strategies specifically for
your circumstance. For more information,
