production at the insertion of the ODSLs and is
generally considered to be an incidental radiographic
finding (arrows).

the palmar/plantar proximal aspect of P2 may proximally displaced (Fig. 1.661). Fragmentation
be encountered. With complete disruption of at the base of the PSBs represents avulsion of the
the distal sesamoidean ligaments, the PSBs are DSLs (Fig. 1.662).
