22 APPENDIKS
4. Articulatio sacroiliaca
Facies auricularis of the Os coxae, as well
as of the Os sacrum are scorede.
The lesion is mostly located at the posterior
half of the joint surface.
At least 75 % of each Facies auricularis
has to be preserved for the area to be
scored
/ The bone is missing, or the bone is preserved less than 75 %

Normal smooth bone, which have no lesions as described below,
but there may be other lesions related to post-mortem damages
or other pathological conditions.
The lesion evolves through various steps, which all can be present
at the same time. The first step is the presence of an erosive
area, which can be more or less grained. Later the grained
area evolved into a cluster of edgy pits. The combination of clusters
will perforate the bone surface and cause an oval, circular or
coalesced shaped hole at the bone surface, and the trabecular
bone will be exposed. The step of perforation is mostly supplemented
by bone bumps and irregularly, rounded exostoses. (ill.
12) The reactive bone growth which causes the exostoses also
tends to smoothen out the lesions edges.
There can be penetrations without the exostoses, but exostoses
without penetration is NOT a lesion, only an indication of age.
After the registration of Facies auricularis, the registrations are combined
under the title: Sacro-iliac
If at least one Facies auricularis from each side is preserved a “0” is
noted, and if just one of the preserved Facies auricularis are registered
as” 1”, then Sacro-iliac also is noted as “1”
