Document Summary

Dislocation of one thumb (left), subluxation of the other (right) Steroids and anti-inflammatory drugs, finger implants (synthetic joints), medical botox (temporary) not as far along as the previous.

Crippling deformity so there is disuse, bone density decreases (osteopenic/fractures) Will be bilateral (will be both hands) Progresses towards trunk then to every joint. Inflammation of synovial membrane causes erosion of articular cartilage underlying bony cortex and ligaments: can develop ankyloses: bony fusion across joint.
