- Bone Grafting for Tibial Fracture:.
- - See: - Bone Graft Harvest Technique: - Papineau Technique: - Posterolateral Bone Grafting: - Tibial Non Unions: - Tibial Defects - Discussion: - upto 60% of high energy open tibial will fail to heal by 20 weeks, and therefore the surgeon must decide which fractures require early bone grafting and which do not; - large defects: - w/ defects less than 6 cm iliac crest bone grafting may be sufficient; - tibial-fibular synostosis using cancellous bone may be indicated in some cases; - w/ defects greater than 6 cm, free fib transfer from contralateral leg is indicated; - see free fibular harvest; - open frx: - indications for bone grafting include segmental defects (more than 2 cm of bone loss may require bone transport), and/or loss of more than 50% of the cortical surface; - after soft tissue coverage is adressed, consider bone grafting; - open fractures treated w/ external fixation: - delayed union is so common that some almost always plan early elective bone grafting at 2-3 weeks post injury; - timing: - as soon as soft tissue envelope is closed and non-infected, bone grafting may be considered; - some recommend bone grafting 5-7 days after debridement, but others argue that early bone grafting may result in resorption of the graft and/or increase in the rate of infection; - grafting options: - osteogenic proteins - some recommend adding powered antibiotic to the cancellous graft; - pure cancellous bone - occasional indication for free fibular graft; - Posterolateral Bone Grafting: - used most in middle and distal third fractures; - advantages: - allows a virgin approach to be used which avoids subjecting previously traumatized area to more insult; - has been successful in treating infected non unions & can be performed w/o disturbing anteromedial soft tissue defects; - allows a large amount of cancellous bone graft to be applied; - Posteromedial Bone Grafting: - may be indicated in proximal third fractures, where posterolateral bone grafting cannot be used due to risk of neurovascular injury; - Anterolateral Bone Graft: - not typically utilized due to the following disadvantages: - risk of increasing compartment pressure and therefore only small amounts of bone graft may be added; - in fractures that were originally open, anterolateral grafting may require an incision adjacent to or thru the original incision site (which can result in wound healing problems or may stir up a chronic nidus of infection); - references: - Anterolateral approach in bone grafting for ununited fractures of the tibia. ...

3. JöG: Grafting seedlings
- www.algonet.se
- Grafting seedlings .
- There are several situations where grafting young plants can be useful: when the species is difficult to grow on its own roots, when you find an albino or monstrose seedling in the batch, or when some catastrophic event occurs (Sciara larvae eat the roots; too much heat destroys the base of the plants). ...
- But, to be honest, I don't do much grafting. ...
- They need to be in active growth when the grafting takes place; the success of it all depends on the top part of the stock being soft and juicy! .
- Classic grafting stock plants include Eriocereus (Harrisia) jusbertii, Trichocereus pachanoi, Trichocereus spachianus and Myrtillocactus. ...
- For seedling grafting, Pereskiopsis is the stock usually mentioned, but I don't have access to it, and to be honest, I think my epiphyte is an adequate alternative. ...
- A sharp knife isn't enough for grafting seedlings. ...
- The grafting .
- A Harrisia martinii (ironically, a rather useful grafting stock) grafted onto 'Jan Kask' survives after years, but hasn't grown more than a couple of centimeters. ...
- A Trichocereus pachanoi (another good grafting stock) on the same stock went adult in a few months, thick and healthy. ...

5. Grafting Australian Native Plants
- www.anbg.gov.au
- Home > ANBG > Horticulture > Grafting First published in the Proceedings of the IV National Workshop for Australian Native Flowers, 28-30 September 1996, University of Western Australia, Perth. ...
- Grafting Australian Native Plants.
- This paper reviews published information and records from the Australian National Botanic Gardens on grafting Australian native plants. ...
- Grafting of desirable forms or species on to different rootstock has been used for centuries to address these problems for other crops. ... Many species that do not root well from cuttings may be vegetatively propagated by grafting. ...
- Generally grafting has been most successful with plants which are very important horticulturally (eg roses, apples), which have a dormant period, and where there has been a long term commitment to trials. ... Other factors that may have contributed to the relative neglect of grafting are the skill level required, the cost and time required for production, problems of re-shooting of rootstock, and the lack of good information on suitability of rootstock. ...
- Some nurseries have been quite successful in grafting Australian plants but this is still on a small scale and for only a limited number of genera (eg Boronia and Darwinia ). ...
- Research into grafting Australian plants has usually been small scale, piecemeal, often poorly controlled from the scientific standpoint, and poorly communicated. ... Most published papers only describe initial successes with grafting and do not revisit plants some years later. ... For example, the general tone of most published information on Banksia grafting might lead one to expect that it had been extremely successful. ...
- Experience at ANBG from the late 1960s to the present serves as a good example of the benefits of grafting, and we are fortunate to have an excellent record keeping system to study the long term survival of our plants. Grafting was a response to the difficult climatic and soil conditions at Canberra which are generally not ideal for a national collection. ...
- Under these environmental conditions grafting allows the cultivation of species that otherwise would not grow on the site. ...
- However by grafting Prostanthera nivea, for example, on to Westringia fruticosa some plants have survived 24 years so far. ...
- Apart from allowing the cultivation of plants that either will not survive at all or are short lived, another major reason for grafting at ANBG has been to propagate and conserve rare or threatened species. ...

- Grafting solves many horticultural problems. ...
- If a friend or neighbour has a particular type of apple you have always admired, why not try grafting a few twigs from that tree onto your own. ...
7. Grafting
- www.ces.ncsu.edu
- Grafting and Budding Nursery Crop Plants.
- Grafting .
- Unlike budding, which can be performed before or during the growing season, most grafting is done during winter and early spring while both scion and rootstock are still dormant. Containerized plants may be moved indoors during the actual grafting process; after grafting, these plants are placed in protected areas or in unheated overwintering houses. ... Indoor winter grafting is often referred to as bench grafting because it is accomplished at a bench.
- For best results, harvest only as much scion wood as can be used for grafting during the same day. ...
- NOTE: In grafting, as well as budding, the vascular cambium of the scion or bud must be aligned with the vascular cambium of rootstock. ...
- One of the simplest and most popular forms of grafting, cleft grafting (Figure 2), is a method for top working both flowering and fruiting trees (apples, cherries, pears, and peaches) in order to change varieties. Cleft grafting is also used to propagate varieties of camellias that are difficult to root. This type of grafting is usually done during the winter and early spring while both scion and rootstock are still dormant. Cleft grafting may be performed on main stems or on lateral or scaffold branches.
- The rootstock used for cleft grafting should range from 1 to 4 inches in diameter and should be straight grained. ...
- In cleft grafting, one scion is usually inserted at each end of the cleft, so prepare two scions for each graft. ... Using a sharp, clean grafting knife, start near the base of the lowest bud and make two opposing smooth-tapered cuts 1 to 2 inches long toward the basal end of the scion. ...
- Thoroughly seal all cut surfaces with grafting wax or grafting paint to keep out water and prevent drying. ...
- NOTE: The temperature of grafting wax is critical. ...

- Four-flap Grafting of Pecans .
- Four-flap Grafting of Pecans.
- The four-flap is a simple grafting procedure that does not require sophisticated materials. Nursery managers, commercial growers, and homeowners can use this grafting method efficiently. ...
- The four-flap graft is successful because more cambium contact is made between the scion and the stock than with any other grafting procedure. ...
- Optimum stock (rootstock) and variety size for grafting is 3/8-1" diameter.
- Grafting is often unsuccessful because graft-wood is not collected and stored properly. ...
- Grafting may be started when buds begin breaking and the bark slips freely (from April to August in New Mexico). Grafting may be continued for several weeks. ...
- When grafting a considerable amount of seedlings, it is better to use a device available in the market that can make the four cuts (or three if preferred) mechanically. ...
- Wrap the cut areas with grafting tape. ...
- Covering the entire scion at this time may improve the chances for grafting survival. ...

11. FNR-105
- www.ces.purdue.edu
- Grafting Black Walnut.
- Black walnut is an unusually difficult species to propagate vegetatively, and until recently, interest in grafting black walnut has been mostly academic with the exception of the grafting of a few nut varieties. For example, since 1968, many grafting and cultural practices have been attempted through Purdue University's black walnut tree improvement program. From the annual accumulation of successes and failures over those years, researchers now can provide a fairly reliable, rapid, but unfortunately, expensive method for grafting and after-care of black walnut which can be used by walnut growers as well as hobbyists. ...
- As long as proper temperature and lighting can be maintained in a greenhouse, grafting can begin as early as February and continue until mid-June. ...
- Collection of the scionwood (grafting wood) should be completed between January and early March. Temperature at time of collection has no effect on eventual grafting success. However, grafting wood should not be collected when wet unless the surface is allowed to dry thoroughly before storage. ...
- Grafting .
- An extremely sharp grafting knife is a must. ...
- If the scion is much smaller than the rootstock at the point of grafting, then be certain that one edge of the scion lines up with one edge of the stock. ...
- The graft union wrapped with a grafting rubber to hold it in .
- Parafilm*, a plasticized paraffin with paper backing may be used to seal the grafting area so that the scion does not dry out before the union is formed (Figure 5). ...
- Paraffin or grafting wax can be used in place of Parafilm. Paraffin wax can be melted and brushed over the entire area of grafting and the scion. ...
- The most crucial condition required to promote grafting success in black walnut is the proper temperature during callusing and early growth. ... Temperature stability is the major reason a greenhouse is an expensive necessity for consistent grafting success. ... Applications of fungicides, hormones, water, and fertilizer to the cut scion, stock, or developing graft have not improved grafting success. ...
