2021 :  New INC (elbow incongruity) grading protocol

Anu Lappalainen was the principal researcher for this study, which was undertaken at the University of Helsinki, Finland. 

"One aim of the study was to develop a radiographic screening programme for short-limbed breeds. The imaging method and grading scheme for elbow dysplasia applied by the Finnish Kennel Club [and other country's Kennel Clubs] today are not suitable for short-limbed breeds as such since they do not take incongruity of the elbow joint into consideration."

  • With effect from 1st January 2021, only elbow evaluations using the new INC grading scheme are accepted by the Finnish Kennel Club for chondrodystrophic (dwarf) breeds.

  • Breeders resident outside Finland can now also make use of this new, more breed appropriate forelimb screening protocol, by visiting the INCOC website, to 'Order grading'.

  • In May 2022, the UK's Breed Health and Conservation Plan (BHCP) was published, listing PCDU as a 'Priority' health issue and calling for monitoring of the uptake of the INC grading scheme by UK breeders.

  • For more information about PCDU (premature closure of the distal ulna) and INC (elbow incongruity) grading, please see the 'PCDU and INC grading' presentation.
