Abstract
AIM: To clarify the diagnostic value of the calcification in the Achilles tendon for Werner syndrome. METHODS: Calcification of the Achilles tendon in the plain radiograph was investigated in 92 patients with Werner syndrome provided from the nationwide secondary survey in 2010. And the same investigation was performed for 2151 feet in 1853 patients without Werner syndrome, who underwent foot and ankle surgeries at the department of orthopaedic surgery in Nara Medical University from 2004 to 2015. RESULT AND CONCLUSION: Achilles tendon calcification was observed in 70 (76.1%) out of 92 patients with Werner syndrome, whereas that was observed only in 19 feet (0.88%) without Werner syndrome, accompanied by 1 to 4 calcified masses with a maximum diameter ranging from 9.7mm to 63.2mm. The frequency of Achilles tendon calcification in patients with Werner syndrome is far higher than that of patients without Werner syndrome. Achilles tendon calcification could be included in the diagnostic criteria for Werner syndrome. Geriatr Gerontol Int 2020; ••: ••-••.
