Loss of Ambulation Due to Calcific Myonecrosis: A Rare but Reversible Complication of Wilson's Disease.

We report two cases of established Wilson's disease (WD) presenting with calcific myonecrosis of the pelvic girdle in association with pelvic fractures. Despite initial improvement with chelation, subacute worsening of ambulation in both led to a consideration of neurologic deterioration on chelation therapy. However, evaluation revealed calcific myonecrosis of the hip joint and adjacent muscles as the cause.
