title: Thiemann's disease.
abstract: Two cases of Thiemann's disease in children are reported for the first time from North America. A history of swollen, tender proximal interphalangeal joints with radiographic evidence of irregularities of the epiphyses leading to premature fusion and subsequent shortening of the middle phalanges resulted in this diagnosis. Recognition of these features should lead to its more frequent diagnosis.
