    Nice study, and interesting that it concludes that there is continuity observed between the fibers of the Achilles tendon and the plantar fascia (in young people)
     
  5. I already knew that, maybe I'd read it somewhere, maybe I'd seen it in dissections, maybe someone told me...

    I'm probably being a bit slow here but is the correlation between age and inferior TA insertion significant in traction apophysitis?

    Yep I've read it in a few previous studies from memory. Can only find one other in my library though. Attached.

  8. Would be interesting to compare with age matched habitual barefooters. That is, is it age, or the length of time for which shoes have been worn?

    Anatomy of the Achilles tendon and plantar fascia in relation to the calcaneus in various age groups.
    Snow SW, Bohne WH, DiCarlo E, Chang VK.

    Hospital for Special Surgery, New York, New York 10021, USA.

    Abstract
    Ten adult cadaver feet, three neonatal feet, and the feet of two fetuses were dissected to investigate whether an anatomical continuity exists between the fibers of the Achilles tendon and the plantar fascia. Histologic sections of the feet were done in three age groups: neonate, persons in their mid-20s, and the elderly. As the foot ages, there appears to be continued diminution of the number of fibers connecting the Achilles tendon and plantar fascia. The neonate has a thick continuation of fibers, while the middle-aged foot has only superficial periosteal fibers that continue from tendon to fascia. The elderly feet show simply an insertion of fibers of both structures into the calcaneus with periosteum in between.

    PS Dr. Bohne is a very smart and experienced orthopedic surgeon

  10. There is a great video around which shows the fascia to achilles connection through discection. They also show how there a single soft tissue connection from the plantar fascia up the posterior leg to the back which ends on the eye brows I think.

    Ill see if I can find it when I get back to Sweden. or maybe someone else can post it up.

    Hi Michael
    Is this one of the anatomy trains ones?

    Nice study.
    I'm surprised at the 55% superior number.
    I would have guessed much less. My surgical experience tells me most insert in the middle.
    It would be interesting to further break this down as to foot type and overall shape variations of the posterior surface.

  13. Notsure Ian got sent to me years ago and then the computer died. I'll try and sourse it in the next couple of weeks.
     
  14. Yes it is Ian. Sorry it took more than a few days....

    You need Quick time media player for these- If you don´t have it follow the instructions worked for me, takes a couple of minutes http://www.anatomytrains.com/explore/dissection

    Look on the right side under multi-media click on and play - this http://www.anatomytrains.com/explore/galleries/show/id/24 shows the fascia connection between the Plantar fascia and Achilles tendon.
