Patients with juvenile spondyloarthropathy who carry HLA B27 antigen or have a family history of ankylosing spondylitis may have marked tarsometatarsal arthritis. This may be associated with hindfoot involvement and result in a supination deformity. Spontaneous fusion with complete obliteration of the tarsometatarsal joints may occur.
