About the Biradial Saw Blade Cut
|
|
(U.S. Patent No. 4,955,888)
|
|
| The biradial saw blade has the same radius on
its inner edge and its outer edge. Because the inner and outer
diameter is matched, the two surfaces of the osteotomy will fit back
together perfectly.
This bone to bone contact provides greater stability and promotes faster
bone healing. |

About A Crescentic Saw Blade Cut
|
|
| A crescentic saw blade has an inner
edge radius that is smaller than the outer edge radius. Because the
inner and outer diameter is not the same, the two surfaces of the osteotomy do not match. |
 |
 |
 |
| Because the osteotomy on the inner edge of the
crescentic blade has a smaller radius, no matter how one manipulates the
osteotomy there will be areas without bone surface contact. This
is of special importance in osteotomies involving weight bearing bones,
such as the TPLO, as it can leave the tibial tubercle unsupported, delay
bone healing and
contribute to implant loosening. |
