I not only think you do not need hip graft bone for Sinus Lifts but it is actually contra-indicated. Autogenous bone from the hip has a high turnover rate and seems to resorb over time. I utilized this bone graft for Sinus Lifts back in the early to mid 1990's. Although we had success, over the following 10 years of follow up there appeared to be tremendous resorption of the grafted bone in the sinus not immediately next to the implant. My own theory is that autogenous bone not "loaded" by the implant was resorbed. This does not happen with cortical-cancellous allograft or Xenograft materials.
Hip grafts for other edentulous areas, not the sinus, may be effective when over corrected and mixed with a low turnover bone product.

I cant believe there are people doing that. I use a xenograft works awesome without invasive surgery of taking a hip.

I agree, it is overkill.

Dr. Holtzclaw, I could not agree with you more! When you consider the cost, morbidity and outcome, you have to ask yourself............... Why?

I usually save this for extreme jaw recon's. I dont see the advantages of taking a hip anymore with so many products that can achieve similiar goals.

With all of the lit on sinus lifts, there is absolutely no reason to go to the hip for bone.  None!  In my opinion, this borders on malpractice!  When I bring this point up to "hipsters", they can never cite any lit to back up their position. 

Bone grafts from the hip for augmentation vary widely in results for several reasons. When travecular bone is used as the graft, resorption of 50% or more can be observed during the first 6 months. Therefore a barrier membrane should be used maintain the space. Cortical grafts from a femur resorb much less and volume reductions of 10% to 20% are common, although one quarter of the time less than 10% is observed.

The harvested bone takes more than 1 year to become mature bone. Re-entry at 2 months is too early- it alters the blood supply are a critical time to the graft, the implant surgery does not stop the resorption (it will continue and the implant may become compromised) and a cortical graft may become destroyed during implant insertion.

Re-entry at 6 months is optimal, although experienced clinicians may be able to use a 4 month time frame. At 6 months most of the resorption is complete, so you can evaluate if additional augmentation is needed before or during the implant insertation is required and although the graft is not all mature bone, enough bone has turned over to insure the process will continue. The implants are usually allowed to integrate for 6 months which means its host bone is in place 1 year prior to loading. Since regrafting is possible at implant insertion, an experienced surgeon familiar with augmenting procedures is suggested for implant insertion. If not, a CT and longer time frames are beneficial.

Why would anyone do a hip graft for simple augmentation especially a sinus lift. Buy some bio-oss alot cheaper and less invasive to the patient. You will probably get better results.

Hip grafts are only needed in severe resorption cases.
