In obtaining the graft, a circular motor-driven saw can be used to expedite the process. For significant bone loss cases, a medullary graft is superior; however, in less severe instances where non-union is the primary concern, an inlay graft may yield better results. The Albee technique involves exposing and freshening fragments before making longitudinal incisions with twin motor saws to create grooves for the graft. This method requires precise alignment and use of salt solution to prevent overheating. After preparing the site, a graft from the tibia is inserted into the prepared groove using kangaroo tendon sutures for stabilization. Albee also employs this technique in recent fractures, utilizing a modified inlay graft with twin motor saws and doweling machines for better fixation without foreign material. This method offers an alternative to traditional Lane plates.

Bone grafting can also address congenital bone absence or disease-related defects, such as replacing the upper end of the humerus with the fibula. The knee joint has been successfully grafted from a freshly amputated leg in extreme cases.
<Callout type="risk" title="Risk of Infection">Immediate reduction of exposed fragments can lead to infection and suppuration if not properly cleaned and sterilized.</Callout>
The treatment of compound fractures and dislocations involves thorough washing and removal of devitalized tissue. Immediate internal fixation should be avoided unless the wound is aseptic, as it may introduce harmful bacteria.

Key Takeaways
- Medullary and inlay graft techniques are effective for treating non-unions.
- Motor saw equipment is crucial for precise bone graft preparation.
- Immediate reduction of exposed fragments can lead to infection if not properly sterilized.
Practical Tips
- Use motor-driven tools like twin saws for accurate bone cutting.
- Ensure thorough cleaning and removal of devitalized tissue in compound fractures.
Warnings & Risks
- Avoid immediate internal fixation unless the wound is aseptic to prevent infection.
- Improper use of antiseptics can harm living tissues and reduce resistance to infection.
Modern Application
While modern surgical techniques have advanced, historical methods like bone grafting remain relevant. The principles of precise cutting, thorough cleaning, and proper fixation are still applicable today. However, advancements in sterilization and materials science have improved outcomes and reduced risks.
Frequently Asked Questions
Q: What is the Albee technique for bone grafting?
The Albee technique involves using twin motor saws to create precise grooves in fractured bones where a graft will be inserted. This method uses kangaroo tendon sutures to stabilize the graft and avoid foreign material within the wound.
Q: Why is immediate reduction of exposed bone fragments discouraged?
Immediate reduction can lead to infection if the exposed fragment or articular surface is considered infected, potentially causing suppuration in the surrounding tissues due to improper sterilization.
Q: What are the key steps in treating compound fractures and dislocations?
Key steps include thorough washing of the wound with sterile salt solution, removal of devitalized tissue, prompt drainage if infection occurs, and cultivation of granulation tissue for proper healing.
