Kager’s Triangle Fat Pad Inflammation and Edema

Kager’s Triangle Fat Pad: This fat pad can have inflammation and edema develop. The most common cause is Achilles tendonitis or even more SEVERE damage.

What Is The Kager’s Triangle Fat Pad?

  • Kager’s fat pad is located above the back of the heel.
  • It is frequently effected by changes to the achilles tendon.
  • It is also effected by changes to the calcaneus & tibia.

 

Kager’s Fat Pad Edema:

  • Kager’s fad pad edema can occur when there is any damage at all to the Kager’s triangle and the fat pad within this.
  • The fat within this area does not really serve any anatomically purpose and it does not actually get sore by itself.
  • The main problem with this is that as the structures around this get sore you can get some swelling.

 

Kager’s Fat Pad Inflammation Treatment:

  • The best way to provide Kager’s fat pad inflammation treatment is to correct the problems causing the swelling and inflammation within this structure.
  • The number one most common cause is achilles tendonitis.
  • Wearing proper shoes, proper inserts and proper support can take care of this the quickest.
  • This is also known as heel bursitis, this is something that can very easily be treated.

 

Kager’s Triangle Fat Pad Has 3 Borders:

  • The calcaneus inferiorly.
  • The achilles tendon posteriorly.
  • The tibia and flexor hallucis longus anteriorly.
  • The retro-calcaneal bursa is sutated in the posterior inferior of the triangle.

 

Non-Achilles Tendon Changes In Kager’s Triangle Fat Pad:

Decreased appearance in:

  • Posterior ankle joint effusion.
  • Retrocalceanal bursitis, at the posterior inferior corner.
  • Os trigonum syndrome at the posterior talus.
  • Flexor hallucis longus tenosynovitis.
  • Fracture of the calcaneus.
  • Calcaneal bone tumors.
  • Any cortical disruptions in the area.

 

Achilles Tendon Changes In Kager’s Triangle Fat Pad:

  • Decreased appearance in:
  • Achilles tendon peritendinitis.
  • Fully ruptured or partially ruptured Achilles tendon.
  • Inflammation or degeneration of the Achilles tendon (tendinosis).
  • Positive Arner’s sign: tendo achilles deviates anteriorly due to rupture.
  • Toygar’s angle decrease: normally 150 degrees, but gets smaller after rupture. The skin becomes more concave and a dell is appreciated.
  • Ossification of the Achilles tendon.

 

 

Flexor Hallucis Longus Changes In Kager’s Triangle Fat Pad:

  • Os trigonum syndrome is the most common abnormal condition.
  • This is usually due to micro trauma & chronic inflammation of the cartilaginous synchondrosis.
  • The ossicle may be fractured.
  • This usually shows concurrent inflammation of the FHL.
  • There could also be full tears, partial tears and tenosynovitis.
  • Various sheath tumors are possible as well.
