Hi @bobbi AVN is Avascular Necrosis (also known as osteonecrosis and other names) It is the death of bone tissue due to a lack of blood supply.. it leads (or did in my case and I'm sure many others) to tiny breaks in the bone and the eventual collapse of the bone/joint. The hip is the most common joint for AVN, but the knee and shoulder are also often involved. It's more prevalent among youngish men, probably because trauma (such as a break or dislocation) is one of the main causes of the interruption of blood flow and youngish men are the ones that indulge in behaviours more likely to risk trauma! There are other reasons, alcoholism (not me)
steroid over use (not me)
SLE or Lupus or RA (testing under way for me) ... or the old "idopathic" meaning they don't' really know why (probably me!!)
which accounts for about 15% of cases
There is a great article in the library regarding different approaches, here's a link, lateral is more closely related to Anterior, in that it disturbs less soft tissue giving a generally quicker and "easier" recovery with less restrictions, Posterior involves cutting (well separating) the gluteal muscles and cutting the capsule that protects the hip... more soft tissue to heal and why Posterior Approach THRs are more prone to dislocation (which is what the restrictions, or precautions, are designed to reduce the already low risk of) Sometimes you don't get to choose which approach you get, I had to have Posterior because it gives a better field of view which was needed in my case, you go with the best recommendations of your OS for the best outcome for you :cool:
