Ankle Sprains
A common injury in
racquetball as well as in many sports is the sprained ankle. You're chasing down
a cross-court pass in the third game tiebreaker...you're tired and you're trying
to concentrated on the ball...your mind says execution but your body says I'm
tired and what often happens is your leg doesn't quite make the next step, your
shoe catches on the floor and your body drags over your ankle. The best thing
to do in this situation is roll with your fall...but too often you'll try to stop
your momentum using a "turned ankle" and subject it to excessive weight
and stretch...resulting in a soft-tissue injury or sprain.
What is a sprain?
A sprain is an injury to
a joint that results in the stretching or tearing of ligaments and possibly the
joint capsule and tendons.
Ligaments are sheets or bundles of fibers that form a connection between 2 bones.
They help strengthen the joint to reduce injury. When the ligament is forced beyond
its anatomical limit then injury occurs.
Causes of Ankle Sprains
Inversion sprains
- this happens when the sole of the foot is directed toward the body and the foot
is extended.
Eversion sprains - this happens when the sole of the foot is directed away from
the body and the foot is flexed.
Syndesmotic sprain - this can happen when there is a severe inversion or eversion
sprain. These severe sprains usually have an extreme rotation component causing
a tear or rupture of the ligaments.
Most Commonly Affected Ligaments
Outside or lateral side of the foot
These are called inversion
sprains. This is the most common place for an ankle sprain. The ligaments affected
are the anterior talofibular, calcaneofibular and posterior talofibular.
Inside of medial side of foot
These are called eversion
sprains. They represent only 5-10% of all ankle sprains. The ligaments affected
are the anterior tibiotalar, tibionavicular, tibiocalcaneal, and posterior tibiotalar.
Upper Ankle
These are called syndesmotic
sprains. This injury usually happens in conjunction with a severe inversion
and/or eversion sprain. The ligaments affected are the anterior tibiofibular
and posterior tibiofibular.
Sports and Sprains
Sports that have
a lot of side to side movement and jumping are prone to causing ankle sprains
(racquetball, basketball, tennis, rugby, volleyball, soccer, etc).
Immediate Care of Ankle Sprains
When an ankle sprain
occurs, the ligaments and tissues are torn causing blood to flow out from the
broken blood vessels and fill the spaces between the cells. This causes the
swelling and discoloration that is commonly seen. Swelling is the biggest
cause of pain and discomfort.
R.I.C.E. (Rest - Ice - Compression
- Elevation)
All of these reduce swelling
and ultimately help recovery.
Rest reduces the body's blood flow and reduces the amount
of blood loss from theh broken blood vessels. This means remain off your ankle
as much as possible and definitely do not return to strenuous activity for a minimum
of a week, depending on how severe the sprain is. If activity is started too soon,
you can end up with an even worse sprain or ankle discoloration. This is because
the ligaments are not healed enough. Ligaments do not have a good blood supply
and the healing time is therefore longer than you might expect. Even when you
can walk on your ankle without pain, it may still not be completely healed. Refer
to a trained physician to know when you can start activity again.
Ice constricts the blood vessels and reduces the blood flow to the injured
area. Ice should be applied as soon as possible after the injury.
Crushed ice is best because it forms nicely to the ankle. If a reuseable freezer
pack is available then be sure to use a towel between the skin and the pack. Reuseable
packs keep cool much longer than ice and can result in frostbite. Ice should be
applied directly over the swelling and painful area. You should "ice"
the site for 15-2- minutes and repeat this every hour.
Compression keeps the blood from expanding into the skin and forces it
back into the bloodstream. Use a 4-ince Ace wrap. These can be bought at the local
Walgreens or Walmart in the first aid department. The wrap should be snug but
not too tight as to cut off circulation. It should be tighter around the foot
and looser above the ankle. After you are done wrapping the injured ankle, squaeeze
your big toe nail and then let go and see if the bed returns to pink quickly (1-2
secs). If the nail bed does not return to pink quickly then the wrap is too tight.
Keep the wrap on during the day but never wear the compression wrap at night.
Elevation encourages the blood to flow back into the bloodstream. This
is the most effective way of reducing swelling. Keeping the ankle elevated above
the heart and preferably above 45° will help a lot. If you don't have ice
or a compression wrap, then you can still elevate the leg. Elevation while you
are sleeping will greatly reduce the amount of pain that you will have in the
morning.
Prevention
Strength Training
Keeping the lower leg and
ankle strongand flexible are very helpful in preventing ankle sprains. People
who are at a desk all week and only play a few games over the weeken are at greater
risk of injury than those who train 2-3 times a week.
Balance and Proprioreception
Having balance and
proprioreception is essential to athletes. Proprioreception is the ability to
determine where a joint is in space. This helps the brain know if the body is
off-balance.Proprioreception is especially important to athletes who have had
ankle injuries. When tissues tear the neurons also tear thereby decreasing the
ability to know where the joint is in space. Therefore, it is essential that the
athlete regains proprioreception by completing rehabilitation therapy. The lack
of balancing ability can result in a greater risk for injury or reinjury. Balance
and proprioreception can be increased by standing on one leg on a flat surface
or wobbly surfaces such as balance boards or trampolines. All exercises can be
made more difficult by closing your eyes.
Footwear
Proper footwear is very
important when playing a sport that has a lot of side-to-side movement and jumping.
The shoes for any particular sport are designed to decrease the forces placed
on the ankle by that particular sport. Running shoes are made for straight-ahead
activity and should not be used for activities such as racquetball which require
side-to-side movements. If you have a history of ankle sprains, then try using
high-top shoes. They offer a greater support than do low-cut shoes.
Ankle Braces
Lace-up supports and
semirigid ankle braces have been found to help decrease the number of recurrent
ankle sprains.
Effects of Repetative Sprains
Prevention and complete
rehabilitation of ankle sprains are the best ways to reduce the number of ankle
sprains you may receive. When a lot of ankle sprains are sustained, there is the
possibility for chronic inflammation of the tendons resulting in tendonitis, degeneration
of the ankle cartiage, and arthritis.
