Consequences of removing marrow tissue from femurs?

Edit Post

Most doctors say that the bone marrow is simply fat tissue in adults and doesn't have many functions

My knowledge of biochemistry indicates the opposite, that the marrow tissue creates the majority of the cells in the body, blood, and immune

I am assuming the reason this surgery is hard on the body is because it physically removes a lot of the tissue that helps repair your body

Any insight on this? It's the main reason I am reluctant to get this surgery

one marrow definietly has some function. i think it has to do with stem cells...
noone really knows what the longterm consequences are. might just be unable to walk after 40 or 50 coz ur legs
deteriorate

I am looking at recovery rates and complications from bone marrow donation and they seem more common than LL complication rates

Google states that it takes 2-6 weeks to regenerate your bone marrow after a donation so I am assuming it will be 3-4 months for a larger amount in limb lengthening procedures

I will have some consultations with LL doctors to clarify the specifics on the removal of the marrow tissue

In the "long bones" like femurs and tibias, yes.

Marrow in other bones is doing that in adults.

Its perplexing to deceive patients about dysfunctions after bone marrow removals and if removing marrow will paralyze patients without elaborations,patients will accuse them of deceits and surgeons will owe more money.

Let's catch up on some basic human physiology here

1) There're 2 types of bone marrow, red and yellow. When doctors are referring to bone marrow being fat, they're referring to yellow marrows which covers most of your bone.

2) The end of big bones like your hip/upper femur, contains spongy tissues or red bone marrow. These host stem cells needed to grow red blood cell, white blood cells and platlets.

In your procedure, you will suffer significant internal bleeding, because the upper femur containing red bone marrow will be drilled through. However, most of the nail goes through parts of the bone with only yellow bone marrow which is just fat.

There is likely to be small, short term effects on your blood cell production capacity. I remember being pale and had low iron levels for a week after surgery. However, everything recovered fully in the coming weeks.

People who need bone marrow transplant aren't lacking marrow, but that their existing red marrow is defective, and can't produce blood cells in sufficient quantities.

If you're a healthy adult (children relies much more on their red marrow), you should recover any red marrow losses quickly and without much complication.

Great response!

Please say a word on TIBIA marrow, is the aforementioned Important red marrow only present in the Femur? Does the tibia play no part whatsoever in this marrow production cycle?

If there is red marrow in the tibia, i suppose the amount is insignificant compared to the one in the femur?

The tibias have very limited red marrow, therefore they don't play a big role in blood production.

Most of your stem cell production are from the red marrow in your hip bones and spines. They are also the most varied and complete in the types of cells they produce. This is why marrow donation are usually extracted from the hip or spines.

Below are the locations of your bone marrow. Note that infants need their entire skeleton to produce stem cells because they are growing rapidly. Eventually as our bones grow, most new bone marrow are yellow (fat).

People have died. I've heard that they get something signed before they operate on their patients. You think some potential deceit accusation after 30 years worries them?
