Autologous Bone Graft – Obtaining Techniques

7f96b48eff9b7a8f8ebe955363b7b260 2

Autologous bone graft is used in various situations in orthopedics, traumatology and mainly in reconstructions of orthopedic oncological surgeries.
In bone defects, it is certainly what promotes the best and fastest bone consolidation, has the best integration and fastest remodeling.
Secondly, we can resort to homologous bone graft, bone from a tissue bank, obtained from a cadaver, which has the disadvantage of antigenicity, has a higher rate of infection, takes longer to incorporate and structural fragility can occur in the integration process. Lastly, we can mention artificial freeze-dried products, which aim to be osteoinductive.
Our objective is to publicize the technique we use to obtain the greatest amount of bone graft with the lowest morbidity.
We believe that, whenever it is possible to use the autologous graft, we will be providing the alternative that allows the best result.
When we need a small amount of graft, we don’t question its indication too much. As an example, in the case of the need to resect the proximal 3/4 of the radius, due to a tumor lesion, which we intend to resolve by performing a distal radio-ulnar “synostosis”, figures 1 to 4.

When we need Reconstruction with opening of the distal radio-ulnar syndesmosis, interposition of an autologous bone graft and fixation with two fragmentary Inter screws, figure 2. Three years after performing the distal radio-ulnar synostosis, we can verify the consolidation, the total integration of the graft and observe that the radius and ulna phases continue with symmetrical growth, with good function, figures 3 and 4.

Figura 6: Radiografia da pelve evidenciando área mais escura na asa do ilíaco, correspondente à baixa densidade óssea. Pelve com trans iluminação mostrando que naquela área central as tábuas interna e externa se fundem. Nesta zona NÃO há enxerto.
Figure 6: X-ray of the pelvis showing a darker area on the iliac wing, corresponding to low bone density. Pelvis with trans lighting showing that in that central area the inner and outer boards merge. There is NO graft in this area.
The need to obtain grafts in quantity, to make major biological reconstructions viable, made us improve the surgical technique to obtain autologous grafts with less morbidity and in significantly greater quantities. Is it possible to obtain an autologous bone graft to fill a large bone defect, of just one internal plate of the iliac, like the one in figure 7? Let’s demonstrate that yes, it is possible, figure 8.
Figura 7: É possível obter enxerto ósseo autólogo para preencher toda esta falha óssea, de apenas uma tábua interna do ilíaco?
Figure 7: Is it possible to obtain an autologous bone graft to fill this entire bone gap, from just one internal table of the iliac bone?

The graft obtained must be applied in the reconstruction in order to avoid the formation of pseudoarthrosis lines, which will be explained later. The key points and technique for obtaining a good graft from the iliac bone are described in figures The incision must be superficial, only in the skin and subcutaneous tissue, so as not to damage the lateral femoral cutaneous sensory nerve. Before proceeding with the dissection, we carefully cauterized the subcutaneous vessels with electrocautery. figures 9 and 10.
Figura 9: Ampla incisão superficial, apenas na pele e tecido subcutâneo, para não lesar o nervo sensitivo fêmur cutâneo lateral, para obtenção de enxerto ósseo.
Figure 9: Wide superficial incision, only in the skin and subcutaneous tissue, so as not to damage the lateral femoral cutaneous sensory nerve, to obtain a bone graft.

Figure 10: Hemostasis with careful cauterization of the subcutaneous vessels.
Figura 11: Realiza-se o descolamento do sub-cutâneo lateral e medialmente, nova hemostasia e com o bistuti elétrico desinserimos os músculos oblíquo do abdomem e ilíaco.
Figure 11: The lateral and medial subcutaneous tissue is detached, new hemostasis is achieved and the abdominal oblique and iliac muscles are removed using an electric scalpel.
Figura 12: Esta desinserção inicia-se anteriormente por sobre a crista ilíaca e vai desviando para lateral póstero-inferiormente à crista.
Figure 12: This disinsertion begins anteriorly above the iliac crest and deviates laterally postero-inferior to the crest.
Figura 13: Desinserimos o músculo ilíaco da espinha ilíaca antero superior e rebatemos cuidadosamente o nervo sensitivo fêmoro cutâneo lateral da coxa.
Figure 13: We detach the iliacus muscle from the anterior superior iliac spine and carefully retract the lateral femorocutaneous sensory nerve of the thigh.
Figura 14: Com uma gase "ruginamos" o perimísio do músculo ilíaco, separando-o da tábua interna.
Figure 14: Using gas, we "roar" the perimysium of the iliac muscle, separating it from the internal table.
At this stage, with the detachment of the thin periosteum, there are a large number of nutrient vessels that begin to flow blood. These must be obliterated with bone tissue hemostatic, aiming to buffer them. We need to notice that there is a small area of ​​the iliac bone where the external and internal plates are very close, almost fused. In this small “island” there is no graft (marked by the yellow arrow), figure 15. After this adequate hemostasis, we place the tip of a compress in the greater sciatic notch and leave it over the sacroiliac, to dam the blood and the graft . We begin with an osteotome to remove the upper cortex of the iliac crest. We must begin graft removal with controlled hemostasis, figure 16.
Figura 15: Hemostasia da tábua interna. Calibrosa artéria nutrícia, que é obliterada com cera para osso, seta vermelha. A seta amarela assinala a região clara, onde a tábua interna e a externa se fundem. NÃO HÁ ENXERTO AÍ!

Figura 16: Retirada da cortical superior da crista ilíaca, com osteótomo. Boa hemostasia, sangramento controlado.
Figure 16: Removal of the upper cortex of the iliac crest, with an osteotome. Good hemostasis, controlled bleeding.
With curved and sharp osteotomes, modeled on the anatomy of the region, we remove the inner cortex in the thinnest layer possible. Exposure of the spongy tissue allows blood to drain. This blood should not be aspirated, it should be allowed to collect at the bottom, forming a clot. This collected blood has potent toti cells. It will be collected with a compress and placed in a vat where we will store the obtained graft, nourishing and preserving it, figures 17 to 19.
Figura 17: Retirada da cortical interna em camada a mais fina possível. Coágulo ao fundo proveniente do sangue que escorre ao retirar-se a cortical. NÃO deve ser aspirado.
Figure 17: Removal of the inner cortex in the thinnest possible layer. Clot at the bottom originating from the blood that drains when the cortex is removed. It should NOT be vacuumed.
Figura 18: Esquema ilustrativo da retirada da cortical da tábua interna do ilíaco. Vamos retirando a cortical que não está coberta pelo coágulo coletado no fundo.
Figure 18: Illustrative diagram of the removal of the cortex from the internal table of the iliac. We are removing the cortex that is not covered by the clot collected at the bottom.

Figure 19: Scheme illustrating the internal cortex removed, bypassing the area without a graft, so as not to perforate the iliac bone.

After removing the entire inner cortex, we store the graft in a vat, soaked by the collected clot, thus preserving the totipotent cells, which will also be placed in the bone defect. Next, with a sharp chisel and WITHOUT using a hammer, we proceed with the removal of the spongy iliac bone, figures 20 to 23.

Figura 20: Tábua interna do ilíaco com todo o osso esponjoso exposto, após a retirada da cortical interna.
Figure 20: Internal plate of the iliac bone with all the cancellous bone exposed, after removal of the internal cortex.
Figura 21: Devemos retirar o enxerto esponjoso "RASPANDO" o osso com formão afiado, com ligeiros movimentos de pressão e rotação. Não se deve bater com martelo.
Figure 21: We must remove the cancellous graft by "SCRAPPING" the bone with a sharp chisel, with slight pressure and rotation movements. Do not hit with a hammer.
Figura 22: Osso esponjoso sendo recolhido com pinça. Não se aspira o sangue, coleta-se o coágulo com compressa, à medida que houver necessidade de visualizar a profundidade, para coletar mais enxerto.
Figure 22: Cancellous bone being collected with forceps. The blood is not aspirated, the clot is collected with a compress, as there is a need to visualize the depth, to collect more graft.
Figura 23: Após o emprego de formões afiados, completamos a raspagem com curetas.
Figure 23: After using sharp chisels, we completed the scraping with curettes.
With this care in collecting the graft, without the use of a hammer, by “scraping” the internal table, already decorticated, we do not drill the bone and maintain the iliac anatomy as much as possible, figure 24. The graft obtained is placed in a vat together with the collected blood, preserving the nutrition of the totipotent cells by imbibition, figure 25. This graft must be fixed, mixing the cortical bone material obtained with the spongy part, to be placed in the bone gap, figure 26. In the gaps segments, we must obtain splinters and intertwine them, making a tie, as a bricklayer lays bricks when building a wall, avoiding the formation of traces of pseudarthrosis, figure 27.

Figure 27: In segmental reconstructions, the graft must be placed interlaced, to avoid lines of possible pseudarthrosis.
Note in figures 28 and 29, x-ray and photo of the iliac bone, the evidence of the absence of a graft in the area indicated by the yellow arrows. On the radiograph, the rarefaction area and the transparency of this region are highlighted by transillumination.

Figure 29: Iliac bone by trans illumination, we can see the absence of graft in this "island", indicated by the yellow arrow.
When the patient needs to be positioned in the prone position, as in spinal surgeries, we can obtain an autologous graft more easily, exposing the iliac bone. In this approach, the best incision is horizontal, at the level of the posterior superior iliac spine. This incision is more cosmetic and can be easily hidden by a bikini, in addition to facilitating both the exposure of the iliac crest and the posterior column, figures 30 and 31.
Figura 30: Incisão horizontal, na altura da espinha póstero-superior, para exposição da tábua externa e retirada de enxerto do ilíaco posterior.
Figure 30: Horizontal incision, at the level of the posterosuperior spine, to expose the external table and remove the posterior iliac graft.

Figure 31: Asepsis and antisepsis for horizontal incision, at the level of the posterosuperior spine, to expose the external table and remove the posterior iliac graft.
We incise the skin and subcutaneous cellular tissue, perform careful hemostasis and remove the perimysium of the gluteus maximus muscle. We place Hohmann retractors supported on the iliac crest and reflect the subcutaneous tissue superiorly, Figure 32. The same detachment is performed distally and we support a Bennet retractor on the greater sciatic notch and remove the external cortex, Figure 33.

Figure 33: External cortex removed and exposed for removal of the cancellous graft. Yellow arrow highlighting the "island", which must be preserved. Blue arrow marks Bennet's retractor, supported on the greater sciatic notch.
We scrape the spongy bone with sharp chisels and remove the graft from the sacroiliac region, crest and posterior column. We perform hemostasis of the nutrient vessels with bone wax, figure 34. The graft obtained is chopped into thin sticks, to facilitate reabsorption and reintegration, figure 35.

Figure 35: Bone graft chopped into thin sticks.

It is important to remember the concept of repairing bone defects with bone grafts: IN A BIOLOGICAL RECONSTRUCTION, EVERY BONE GRAFT  PLACED TO FILL CAVITIES OR SEGMENTAL FAULTS GOES THROUGH A  REABORTION PHASE  TO  BE LATER REINTEGRATED , REPAIRING THE BONE LOSS. The graft must be intertwined and go beyond the level of the osteotomy, avoiding pseudarthrosis, as exemplified by this case of chondrosarcoma in figures 36 to 38, blue arrows.

The iliac bone is also a rich source of structural graft, with better quality in terms of integration than the fibula. Obtaining this type of graft deforms the anatomical contour of the pelvis, as there is a need to remove the iliac crest together with the internal and external cortex, forming a triangular block, as exemplified by the cases of simple bone cyst, shown in figures 50 to 60.

The fibula can also be used vascularized in reconstructions, including with the growth plate to replace the one that will be resected due to the tumor. It is a fibula autotransplantation with the physeal plate, performing osteosynthesis with the extensible internal fixation device, figures 63 and 64.
