First Bone Mill Capable of Meeting
the Required Grading Criteria* for
IMPACTION BONE GRAFTING
Bone: Frozen bovine femoral head;
Blade: 3-8 mm, for impaction grafting.

Innovative Technology and Design
for Creating Ideal Bone Graft
The design of the Universal Bone mill is based on the design of our HR500 Spinal Bone Mill and the findings of N.T. Brewster et al*. The authors found that the particle size distribution profile of a well-graded bone graft, one having optimal mechanical property, is similar to the Fuller or modified Fuller curve, depicted in the graph.
Significant innovation was required to meet the Brewster's grading requirements.
As the technology leader in the industry our HR500 Spinal Bone Mill, introduced in 2014, has successfully provided superior bone grafts for patients, in the USA and overseas.

Washed re-milled graft
Milled femoral head
In a gathering of professors and hip surgeons, Cenna Medical had the opportunity to demonstrate the performance capability of The Universal Bone Mill.
Using reciprocating saw, with three consecutive slices the femoral head was cut in 5 pieces. Using 3-8 mm blade, the cut pieces were milled and re-milled. Milling time was less than 2 seconds per piece.
A portion of the milled graft was washed to reveal the aggregates.
The outstanding accuracy, speed and milling power of The Universal Bone Mill for hip surgeons surprised the observers in the THA lab.
