How How The Bone Graft Delivery System Improved?

25 Jul 2019

As days go by, the spinal market and bone grafting technology are shifting towards more uncomplicated and less invasive surgeries. A past study also shows that most people are moving from traditional bone grafts to substitutes grafts in the United States.bone grafting

This has caused several challenges in the delivery of graft to the required area during the surgery process. For instance, expandable cages adversely limit a practitioner’s ability to pre-fill it with graft before placement. Such problems have pushed the appropriate parties involved to come up with the latest bone graft delivery system to ease the process. Bone graft manufacturers have come up with unique bone funnels, cannulas, and syringes to counter these problems.

Why New GDS Usage Should Be Urgent</h3

Traditional procedures for bone grafting have been common for quite a while until recently when most surgeons have opted for less invasive surgery techniques. Bone grafting technology has to speed up to produce devices that are less invasive to the area of injury, delivering graft material, and packing it in altogether.

Take, for example, spinal fusions, which is a common bone grafting procedure performed today. In this process, the affected area needs to remain in place for the longest time possible, which is why surgeons use the open technique to access a small region of the spine.

With new technology, the surgeon will only need to use a tubular retractor by passing it through a small opening at the spinal column. The tool carrying the material can pass through the small opening and can also bend when necessary.

The Past and the Present

Bone grafting is an advancing process, as seen from devices used years back when the process was gaining popularity. Today’s tools can distribute three primary bone grafts during surgery which include:

  • Allograft- the patient’s bone
  • Autograft- a donor’s bone, usually not the patient
  • Synthetic bone graft- graft substitutes

More often than not, surgeons will use these bone grafting delivery devices during the entire process:

  1. Bone funnel: This is where bone-graft material gets mixed with blood, bone marrow, plasma, or any other appropriate fluid for use in this process. A plunger helps quickly push this mixture into the area of concern.
  2. Syringe: A syringe helps push the mixed fluid in the bone funnel through the cannula.
  3. Cannula: This is a short, thin tube that borders the syringe and makes sure the graft material gets deposited in the appropriate target place.

For the above devices, funnels are often made of stainless steel material and need sterilization before and after each use. The disposable plastic syringes and cannulas are usually pre-sterilized so no need for sterilization before use.

To save on time used for surgery, practitioners bring the devices in the surgery room already filled with graft material. Most clinicians also prefer wider and easy-to-curve cannulas to access even the most profound parts during the surgical process.
