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.
