The findings in stage 2BPTTD are similar to those in stage 2A,the addition of lateral pain (sinustarsi,subfibular,cuboid),more severe valgus deformity,collapse of the medial longitudinal arch,and obvious abduction of the forefoot on the rearfoot. Forefoot supinatus may be present in stage 2B.There may also be decreased subtalar joint motion.Contracture of the posterior muscle group is typical. Radiographs show an increase in the talo-firstmeta-tarsal angle on AP and lateral viewsas well as peritalar subluxation.Degenerative changes are usually absent.MRI and ultrasound findings are similar to those found in stage 2A, al though they may also reveal complete tendon rupture.
