Strained Ankle Tendon & Ligaments

Strained Ankle Tendon & Ligaments: Find out what muscles are strained & what ligaments are sprained in your ankle.

 

Strained Ankle Tendon vs Sprained Ankle Ligaments:

 

  • Tendons: are muscular attachments to the bone.
  • Tendons experience strains.
  • Ligaments: are the attachments between bone and bone.
  • Ligaments experience sprains.

Tendons In Ankle:

There are 2 major tendons that can be strained in the lateral ankle.

  • These are the peroneus brevis & the peroneus longus muscles.

There are ligaments on the medial & lateral ankle which are commonly damaged.

  • 5 major medial ankle ligaments.
  • 3 major lateral ankle ligaments.
  • The lateral ankle ligaments are most commonly damaged.

 

Strained Ankle Tendon & Ligaments

There are 5 (Deltoid) medial & 3 lateral ankle ligaments:

 

Strained Ankle Tendon & Ligaments

3 Lateral Ankle Ligaments:

  1. Anterior talofibular ligament.
  2. Calcaneofibular ligament
  3. Posterior talofibular ligament.

 

5 (Deltoid) Medial Ankle Ligaments:

  • 1-2) Superficial & deep tibiotalar ligaments.
  • 3) Tibiocalcaneal ligament
  • 4-5) superficial & deep tibionavicular ligaments.

 

 

Lateral Ankle Ligaments:

Strained Ankle Tendon & Ligaments

3 Major Lateral Ankle Ligaments:

 

1) The Anterior Talofibular Ligament.

  • The anterior talofibular ligament is the most commonly damaged ligament in ankle sprains.
  • This ligament protects against inversion & plantarflexion.
  • If any ligaments are damaged during an inversion ankle sprain, this one is usually included!

2)The Calcaneofibular Ligament.

  • This is the second most common ligament damaged in any ankle injury.
  • This ligament protects against inversion & dorsiflexion.
  • If the calcaneofibular ligament is damaged, then the anterior talofibular ligament is also damaged.

3)The Posterior Talofibular Ligament.

  • The posterior talofibular ligament is rarely ruptured.
  • Both the calcaneofibular ligament & talofibular ligament will be damaged.

 

 

 

 

5 Major Medial Ankle Ligaments:

Strained Ankle Tendon & Ligaments

There are 5 medial ankle tendons:

  • 1)Superficial tibiotalar ligament.
  • 2)Deep tibiotalar ligament.
  • 3)Tibiocalcaneal ligament.
  • 4)Superficial tibionavicular ligament.
  • 5)Deep tibionavicular ligament.

 

 

2 Major Tendons In Ankle:

There  2 major lateral ankle tendons:

  • The Peroneus Brevis Muscle Tendon.
  • The Peroneus Longus Muscle Tendon.

 

Strained Ankle Tendon & LigamentsThere are two major lateral ankle tendons. The peroneus brevis & the peroneus longus.

 

1) The Peroneus Brevis.

  • The peroneus brevis muscle tendon.
    • This muscle is involved in eversion & dorsiflexion of the foot.
    • This muscle originates at the top of the outside leg.
    • It inserts at the base of the 5th metatarsal bone.
    • It can frequently avulse the base of the 5th metatarsal.
    • This avulsion fracture is known as a Jones fracture.

 

 

2) The Peroneus Longus.

  • The peroneus longus muscle tendon.
    • This muscle is involved in eversion & plantarflexion of the foot.
    • This muscle originates at the middle outside of the leg.
    • It runs to underneath the foot and inserts to the base of the 1st metatarsal.
    • This muscle can have an accessory bone.
    • This accessory bone is called an os peroneum.
    • This accessory bone can cause irritate on the bottom of the outside of the foot.
