9. Tarsus
Talus and Calcanus are scored.
The lesions can be located all over the
bones.
At least 75 % of each bone has to be preserved
in order 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 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 fusion of pits 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.
It is important that the edges of the hole and the trabecular bone
are sharp and have the same coloration as the surrounding bone,
or the lesion will be due to post-mortem changes and not tuberculosis.
Often there will be no reactive bone growth at the lesion, except
for a slight smoothing of the exposed trabecular bone.
Due to the lesions the overall look of the bone may look worn
out, and there can be eburnation at the articular surface at a
young age. The eburnation are not scored, it is only a part of the
general description of the lesions.
After the registration of Talus and Calcanus, the registrations are combined
under the title: Foot.
If at least one of the bones from each side is preserved a “0” is noted,
and if just one of the preserved bones are registered as” 1”, then foot
also is noted as “1”
