Dystonia (limb) triggered by ulnar fracture and casting

This woman was well until she sustained an ulnar fracture playing racquetball, requiring a cast. After the cast was removed, she noted a dystonic deformity of her right hand. This peripherally induced dystonia subsequently progressed to segmental and then generalized dystonia. (Contributed by Dr. Joseph Jankovic.)
