[Identification of the best sites for the histopathological study of tarsitis in patients with spondyloarthropathies].

Background: Foot involvement in patients with spondyloarthropathies (SpA) includes a peculiar clinical spectrum ranging from tarsal swelling to bone ankylosis similar to axial disease in patients with ankylosing spondylitis. Hypothetically, the study of these lesions could help to explain phenomena that occur in the vertebral column.

Objective: To identify the best site for sampling foot tissues in cadavers with a view to implementing the procedure in patients with SpA.
