4.5mm shaft screws

Incomplete ossification of the humeral condyles (IOHC) is a problem most commonly seen in English Springer Spaniels and occasionally in other breeds. The condition is characterised by a failure for the condyles to fuse together and may contribute to forelimb lameness and condylar fracture.

Details

Until such time as we are able to reliably stimulate the humeral condyles to fuse together, it seems that the only practical means of managing the problem is to place a large trans-condylar stabilising screw. In that the incidence of fatigue failure is high, it seems sensible to use the strongest screw possible. We have manufactured a range of 4.5mm shaft screws from 32mm to 44mm specifically for this procedure. Andy Moores advises that the 4.5mm Shaft Screw has an AMI (bending resistance) 5 times greater than a standard 4.5m cortical screw. Please note that a tap and screwdriver are required for the shaft screws.
