G-BONE SYNTHETIC & G-BONE MODIFIED HA

Uses: For all kind of Bone Replenishment

FAQs about G-Bone HA

1. Q . How good are G-Bone bone grafting materials in comparison with autologous bone graft.

A . Any bone graft from “outside body” will be always inferior in comparison with autologous bone graft. More over bone graft from iliac crest is a complete bone, whereas G-Bone ceramic bone grafts are only inorganic constituents of bone.

G-Bone, bone-grafting products are only adjunct to Autologous bone graft. It is not a direct replacement of autologous bone graft.

2. Q . What kinds of results are expected from G-Bone bone grafting products?

A . The results with any bone grafting material from outside body will be inferior in comparison with autologous bone graft.

3. Q . Which are the areas where, G-Bone is most suitable?

A . Almost everywhere, where a bone graft is required.

4. Q . Which are the type of cases where it is most suitable?

A . The cases which require small quantity of bone grafting material i.e. less than 20 cc & cavities with more than 3 side walls, best are cavities with 5 side walls

There is a very interesting usage pattern with G-Bone. When the G-Bone is first introduced to surgeons they use it very cautiously and in small quantity. The results are good. They develop confidence. They start using it in more quantities. Results are OK. They are happy. They develop more confidence. Then they use 5-10 packets of G-Bone in one case, results are bad and surgeons are unhappy. Then they compare it with imported brands, but they never used many packets of imported brands in one patient, because it is very expensive and they start saying that G-Bone is not as good as imported brands.

5. Q . how to use it in cases where large quantity of bone grafting material is required?

A . If one has to use more than 20 cc of bone graft material, ratio of autologous bone to be mixed with G-Bone should be increased. For example up to 20 cc size of bone grafting 5-10% of graft should be from autologous bone in more than 20 cc 20-30% should be from autologous bone. In cases where one has to use more than 50 cc, 50-60% may come from autologous bone.

Quality of results will deteriorate as the quantity of bone graft increases.

In cases where large quantity is to be used, a low-pressure suction may be required to remove serous discharge.

6. Q . Which is better G-Bone Modified HA or G-Bone synthetic/ G-Graft for cavity filling purposes?

A . G-Bone synthetic/ G-Graft should give better results for filling of cavities/gaps.

7. Q . Should one-use blocks or granules?

A . Almost 5 years of usage experience has shown that granules are good for very small 1-5 cc of bone grafting. For more than 5 cc of grafting blocks have proved to be better. For larger areas granules have disadvantages such as:

- It gets spilled over and is difficult to contain.

- Granules offer large surface area and serous discharge is more with granules.

- Granules come out with serous discharge before integration.

8. Q . What is the maximum quantity one can use?

A . Larger the quantity poorer are the results . More than 20 cc should be used with great caution.

9. Q . How much time does G-Bone Modified HA take to integrate with host bone?

A . Noticeable absorption of G-Bone Modified HA should be visible after three months. Significant integration with host bone may take 12 months or more. Actual time will vary greatly upon local conditions and condition of patient.

10. Q . How much time does G-Bone synthetic take to integrate with host bone?

A . G-Bone synthetic should take almost 3-6 months to integrate with host bone.

11. Q . What about serous discharge after implantation of G-Bone?

A . Serous discharge after implantation of G-Bone is very common. It is body's reaction to the chemical nature of material. More is the quantity greater is problem of serous discharge. In cases where one has to use more than 20 cc, a low-pressure suction drainage for 10-15 days may be required to remove the discharge.

12. Q . When serous discharge will be more?

A . When granules are used, when larger quantity of G-Bone is used (more than 5 cc) and when graft is directly under skin.

13. Q . How to manage serous discharge?

A . By frequent change of dressing. Large discharge may require low-pressure suction drainage.

14. Q . When the serous discharge will stop?

A . Normally it subsides within 10-30 days.

15. Q . Is the serous discharge due to some kind of infection?

A . NO. It is body's response to irritation by chemical nature of grafting material.

16. Q . What is present status of use of G-Bone?

A . G-Bone bone grafting materials are becoming very popular. Currently G-Bone is also exported to many countries around the world. Its use is spreading almost everywhere in India. There has been almost 40% growth every year.

17. Q . Will integration occur, if there is a gap between host bone and bone graft or some soft tissue is in-between?

A . No, there will not be any integration, if G-Bone is not in direct contact with host bone.

18. Q . Is it safe to use G-Bone directly under skin in bones such as shin of tibia or ulna?

A . Use of granules directly under skin may create problems. It is advisable to use blocks under skin. Try to avoid over fill, slight 5-10% under fill is desirable.

19. Q . Is there any specific contraindications

A . Any kind of bone graft should not be used in infected or potentially infected area.
