Joints
involved are usually insensitive to problems which may be occcuring
within those joints. Swelling is noted with deformity of the joint,
the swelling being intraarticular swelling. The joint changes can
be atrophic or hypertrophic (depending on the stage) or can be both
at the same time. There is an obvious amount of small bony fragments,
with bone destruction actually occuring transverse to the trabeculations
of the bones.
Obvious
dorsal dislocation of the navicular with swelling within
the joint and bony atrophy.

Diffuse
atrophy of the joints of the midfoot. The first metatarsal
has been amputated (left).
|
|
The atrophy and fracturing
of the calcaneus apparently began as a stress fracture of
the calcaneus which was not felt by the patient. This
fracture is transverse to the trabeculations of the
calcaneus.
|
Hypertrophic or healing
stage where the bones begin to reform but obviously not in
any way similar to the 'normal' alignment of the
foot.
|
Unaffected calcaneus, the
destruction being confined to the navicular, cuneiforms and
bases of the metatarsals.
