Peroneus Brevis Tendonitis

Peroneus Brevis Tendonitis

Welcome to the Peroneus Brevis Tendonitis Complete Diagnosis and Treatment Guide.


What Is Peroneus Brevis Tendonitis?

The Peroneus Brevis is a muscle that forms half of the peroneal tendons and when inflamed can cause peroneus brevis tendinitis.

  • The peroneus brevis courses down the outside of your foot starting from the outside of your leg.
  • It continues down the outside of your ankle to the outside bottom of your foot.
  • The muscle and tendon is responsible for turning your foot up and out.
  • If there is overuse of this motion, the tendon can become irritated and lead to pain over time.
  • This motion is especially necessary for keeping your balance during athletics & standing!

Causes of Peroneus Brevis Tendon Injury:

The Peroneus Brevis muscle is the primary muscle responsible for turning  the foot up and out.

  • Although this motion doesn’t seem like one that  would be overworked too often.
  • It is needed in almost any athletic  activity to keep you balanced on your foot.
  • It is even needed to stand for long periods of time.
  • The peroneal tendons can also be damaged any time you roll your ankle as they can become stretched and elongated as your foot buckles inward.


Peroneaus brevis tendon anatomy
The Peroneus Brevis and Longus can frequently be injured by sports that cause ankle joint inversion.

Who Is At Risk?

  • Overuse injury.
  • Standing very long periods at work.
  • Overuse during athletics.
  • Inversion ankle injury (“rolled” your ankle).
  • Injury to subtalar joint or tarsal coalition.
  • High Arch foot.
  • If you have “clicking” it may be a subluxed peroneus brevis.


Peroneus Brevis Tendonitis
A high arched foot can frequently lead to inversion ankle sprains, this can then cause chronic irritation of the peroneus brevis.



Progression Of Injury If No Treatment:

  • The peroneal tendons normally glide through their fibro-osseous tunnel very smoothly.
  • But if overworked inflammation (called tenosynovitis) will set in.
  • This will cause swelling and pain.
  • This will lead to more friction and the situation just starts to get worse before things start to get better.
  • In the end stage a condition called tendinosis occurs where the tendon begins to weaken and eventually degenerate.



Peroneus Brevis Insertion and Origin:


Peroneus Brevis Tendonitis
The Peroneus Brevis starts at the outside of the leg. It then courses around the back of the outside ankle. It then attaches to the base of the 5th metatarsal.


  • The Peroneus Brevis originates from the middle to distal fibula.
  • It courses down the outside of your foot.
  • It attaches on into the styloid process of the fifth metatarsal.
  • if you palpate with your finger, the pain can be felt here.


Symptoms of Peroneus Brevis Muscle Pain

  • Pain in the outer part of your ankle directly behind your outside ankle bone.
  • Pain worsens with overuse but initially gets better after rest when your blood gets flowing.
  • Swelling and redness on the outside of your leg, ankle and foot.
  • If you have “clicking” it may be a subluxed peroneus brevis.


Diagnosis of Peroneus Brevis Tendonitis

  • Swelling and redness on the outside of your leg, ankle and foot.
  • The pain is palpated along the course of the tendon.
  • Pain on turning your foot up and out against tension.
  • Ruling out other problems than peroneus brevis tendonitis on Xray.
  • Ruling out other problems through meidcal history.
  • If a partial tear is suspected an MRI may be ordered if the peroneus brevis tendonitis is severe.


Home Treatment Of Peroneus Brevis Tendonitis:



Peroneus Brevis Tendonitis

It may not always be possible for some athletes, but switch it up to biking or swimming for a little while!

  • No athlete wants to hear it.
  • Any high impact activity will prolong the healing time. try to find an activity that puts less strain on the peroneus longus tendon.
  • These include swimming or biking for at least a week or two.
  • At least until the inflammation calms down.


2) Cryotherapy:

Peroneus Brevis Tendonitis

Nothing as dramatic as an ice bath, but icing for 15-20 mins will help relieve the soreness & speed healing time!

  • This is most beneficial after activity & soreness.
  • Icing 2-3x per day for about 15-20 minutes will decrease the flow of inflammatory cells into the muscle.
  • Afterwards the arteries will vasodilate further flushing out inflammatory cells from the region.
  • Ice has deeper penetrating power than heat.
  • Do not use heat after activity or further irritation of the region.



  • If possible elevate your leg while watching TV.
  • This prevents stasis of the venous backflow within the leg.
  • This is not as essential as cryotherapy, but if possible, it will help!



Peroneus Brevis Tendonitis

Compression socks & stockings can really help out. This increases blood flow & decreases swelling.

  • This is similar to the elevation treatment.
  • Compression socks & stockings are available that could really help you out!
  • It will increase the backflow of venous blood and help flush out inflammatory cells.
  • Use an ACE bandage or any other type of compression wrap.
  • It should not be so tight that it cuts off blood flow!

5)Topical anti-inflammatories or analgesics:

Peroneus Brevis Tendonitis

Topical anti-inflammatory gels work very well in helping to decrease inflammation!

  • There are anti-inflammatory creams that can be prescribed by your podiatrist that can decrease the inflammation and speed up your healing time.
  • Over the counter include Capsaicin.
  • Voltaren or any diclofenac gel works great.
  • Biofreeze or anything with menthol in it.


6)Oral NSAIDs:

Peroneus Brevis Tendonitis

Anti-inflammatory medication can really jump start the healing process. Use it for a 1-2 weeks until the inflammation decreases & your body can start healing.

  • These include Ibuprofen & aspirin.
  • This can be over the counter or prescription.
  • Do not take these unless instructed to do so by your physician or podiatrist.
  • Take a 1-2 week course to attempt to decrease the inflammation and speed up your healing time.
  • Take 2-3x doses per day as instructed, this builds up anti-inflammatory enzyme levels in your system.
  • Taking just 1-2 pills and then stopping does nothing for inflammation!


7) Get Good Shoes:

 Peroneus Longus Tendonitis

Get a good running shoe that fits properly & has a stiff sole.

  • Use a brannock device to fit your shoes properly.
  • Make sure your toe and pinky toes fit properly.
  • Make sure it is a rigid soled shoe (that does not twist very easily).
  • Fit your shoes at night when they are the most swollen.


 8) OTC Orthotics:

Peroneus Brevis Tendonitis

A proper orthotic will aid in controlling biomechanics & decreasing stress on your peroneus longus.

  • Some biomechanical abnormality is causing this strain in the first place.
  • If your foot is off balance, there is abnormal tension your you peroneus longus muscle.
  • An orthotic can counteract this abnormal biomechanical positioning.
  • This will prevent excess strain on your peroneus longus tendon.


9)Physical Therapy:

Peroneus Brevis Tendonitis

Physical therapy will target your sore muscles & strengthen the weakness!

  •  There is a great deal of scientific evidence showing that this will greatly improve healing time.


10) Podiatrist:

Peroneus Brevis Tendonitis
If no conservative treatments have been effective, it may be time to see your podiatrist!

A podiatrist can assess your biomechanical abnormalities & get to the root of the problem!



Peroneus Brevis Tendon Surgery.

  • Surgery is usually not necessary for simple Peroneus Brevis muscle and tendon inflammation.
  • But if there is subluxation then occuring the patient will hear a “clicking noise”.
  • If you hear this clicking noise and the tendon is popping out of its groove you may need Peroneus Brevis Tendon Repair.


Peroneus Brevis Tendon Repair.

  • This procedure may be needed if there is a split tear in the peroneus brevis tendon.
  • A surgical process called intubulation is then empoyed.
  • This consists of taking the two pieces of longitudinally split tendon fibers and suturing them together.


Split Tear Peroneus Brevis Tendon.

  • A suturing technique known as intubulation is employed to suture together the split or torn peroneus brevis tendon.
  • This technique is utilized only for longitudinal tears.



Other Causes of Pain Around the Peroneus Brevis Tendon:

Skin Problems:

Calluses are thick patches of skin that appear in sites of friction against the shoe, the floor or any other part of the foot. The danger is a blister can form underneath the callus!

A corn looks like a little pebble that can form, they usually even occur with a callus around them. This can be exceptionally painful.

Follow our at home pain relief guides, how to trim your nails properly and even how to remove them permanently.

These occur from stubbing your toe, so learn how to deal with them properly! Is it broken or is it just bruised, find out with this guide.


Bone and Joint Problems:

This is when you toe looks really big and as if though its popping out at the base.

This is when you have a crooked or curved toe.
