Preserving Locally Generated Bone During Surgical Procedures
Autologous bone graft remains widely regarded as the preferred grafting material for many spinal fusion procedures because it possesses osteogenic, osteoinductive, and osteoconductive properties while eliminating concerns associated with immunogenicity and disease transmission.
During many orthopedic and spine procedures—including decompression, laminectomy, facetectomy, and spinal fusion—bone is removed as part of the normal surgical technique. When appropriate, surgeons may choose to preserve this locally generated bone for potential use as autologous graft material.
What Is Autologous Bone Graft Collection?
Autologous bone graft collection refers to the recovery of the patient's own bone generated during surgery for potential use during the same procedure.
Unlike iliac crest bone graft harvesting, collecting locally generated bone does not require creating an additional surgical site. The approach may help preserve bone that would otherwise be discarded while avoiding donor-site harvesting.
Sources of Local Bone
During orthopedic and spine surgery, locally generated bone may originate from:
-
Lamina
-
Spinous processes
-
Facet joints
-
Osteophytes
-
Other bone removed during decompression or preparation
The quantity and suitability of local bone depend on the individual patient, surgical procedure, and surgeon's clinical judgment.
Why Local Bone Is Important
Published literature continues to support the use of local autologous bone in appropriately selected spinal fusion procedures.
Potential advantages discussed in the literature include:
-
Preservation of the patient's own bone
-
Elimination of donor-site morbidity associated with iliac crest harvesting
-
Excellent biological characteristics
-
Reduced need for additional graft harvesting
-
Integration into standard surgical procedures
Clinical decisions regarding graft selection remain the responsibility of the treating surgeon.
Methods of Autologous Bone Graft Collection
Several techniques are used to recover locally generated bone during surgery.
These may include:
-
Manual collection
-
Collection from surgical instruments
-
Bone mills
-
Specialized bone graft recovery devices
-
Suction-based collection systems
The selection of a collection method depends on surgeon preference, procedure type, and institutional practice.
Bone Graft Recovery Devices
Modern bone graft recovery devices are designed to collect locally generated autologous bone during surgical procedures while integrating into the surgical suction pathway.
These systems are intended to assist surgeons in recovering bone particulate generated during drilling, decompression, and other bone-removal procedures.
Rimmedtech™ Bone Dust Trap
The Rimmedtech™ Bone Dust Trap is a patented intraoperative bone graft recovery device designed to collect locally generated autologous bone particulate during orthopedic and spine surgical procedures.
Key features include:
-
53 cc internal collection volume
-
Dual-stage filtration
-
Compact operating room footprint
-
Sterile, single-use design
-
Designed to integrate into established surgical suction workflows
The device is intended to support intraoperative recovery of locally generated autologous bone in accordance with its Instructions for Use.
Frequently Asked Questions
-
What is autologous bone graft?
Autologous bone graft is bone obtained from the same patient receiving the graft.
-
What is local bone?
Local bone refers to bone removed during the surgical procedure itself, such as bone from decompression or preparation of the operative site.
-
Why is local bone used?
Local bone provides autologous graft material without requiring a separate donor-site harvest. The decision to use local bone depends on the clinical situation and surgeon judgment.
-
Is local bone different from iliac crest bone graft?
Yes. Iliac crest bone graft is harvested from the pelvis through a separate procedure. Local bone is generated during the primary surgical procedure.
-
What is a bone graft recovery device?
A bone graft recovery device is designed to collect locally generated autologous bone during surgery for potential intraoperative use.
Scientific Literature
Published studies continue to support the use of autologous bone graft and increasingly describe local bone as an important graft source in appropriately selected spinal fusion procedures. Literature has also reported reduced donor-site morbidity compared with iliac crest harvesting while maintaining high fusion rates in many single-level procedures.
