[Cortical hyperostosis of the pisiform bone in stage I Dupuytren contracture in chronic alcoholics].

The author examined the carpalia of 40 male alcoholics suffering from Stage I of Dupuytren's contracture. In four subjects he observed a cortical hyperostosis of the right pisiform bone on the tangential films. The hyperostosis can be ascribed to the ethanol-induced hyperlipoproteinemia type II/B. The lipoids leaving the vascular paths infiltrate the connective tissue capsule of the pisiform bone and stimulate the formation of osteoblasts at the border between bone and soft tissue. The ossification must be regarded as enteropathic hyperostosis.
