Fig. 1 (A) Anteroposterior, (B) lateral, and (C) hindfoot alignment radiographs showing the radiographic variables. A smaller negative heel alignment angle indicates a greater lateral or valgus deviation of the calcaneus. Abbreviations: CP, calcaneal pitch; HA, heel alignment (angle); TMT, talo-first metatarsal (angle); TNC, talonavicular coverage (angle).

Fig. 2 Anteroposterior and hindfoot alignment radiographs of a 59-year-old female with flexible flatfoot deformity associated with varus ankle osteoarthritis and peritalar instability: (A and B) preoperatively and (C and D) 29 months postoperatively. Note that mortise-plasty osteotomy addressed the supramalleolar and intraarticular varus deformities, and calcaneocuboid distraction arthrodesis corrected the inframalleolar valgus deformities.
