What is Peroneal Insertional Tendonitis?

Tendons are soft tissues that connect the bones and muscles, and they help with our movement while also absorbing the tension caused while moving. When overused, these tendons can get inflamed causing tendonitis. Peroneal insertional tendonitis is inflammation of the peroneal tendons that exist in the foot. People who are into sports are known to are known to suffer the most from peroneal insertional tendonitis.

Peroneal Insertional Tendonitis:

As mentioned above, the peroneal tendons in the foot get inflamed or irritated because of overuse leading to this condition. There exist two peroneal tendons, viz. peroneus brevis and the peroneus longus. These tendons are there to help with the foot’s and the ankle’s stability and to keep them from spraining.

But sports persons owing to the sport they play and the training they undergo tend to overuse their tendons, in the process inflaming them, and thus tendonitis.

It is usually the peroneus brevis that gets inflamed and experiences this tendonitis problem. Sometimes, the peroneus longus may also experience tendonitis or in some cases, both the brevis and the longus muscles can get inflamed, and if abnormal load is placed on the tendon, it eventually develops into tendonitis.

Symptoms:

Let us look at the symptoms that are exhibited by the person suffering from the syndrome.

  • When the peroneus brevis is the one that is injured, then one experiences severe pain at the point where this tendon inserts into the fifth metatarsal.
  • If the peroneus longus is the one that is injured, then pain is felt at the bottom towards the arch.
  • Initially, the pain might seem very mild, and may be present when an activity is begun. But the pain would gradually subside once into the activity.
  • There is no swelling or redness associated with this problem.
  • The problem can be either an acute or a chronic one. Chronic injuries lead to an unstable ankle, subluxation and inversion injuries.

Treatment:

Peroneal insertional tendonitis takes a long time to heal, as the blood supply to tendons is affected. So, massaging and exercising the peroneal tendons becomes very important.

  • Anti-inflammatory drugs are required, as the tendons get inflamed.
  • The injured foot should also be rested properly.
  • A surgery may be required if the injury is a severe one.
