“…Division of Foot & Ankle Surgery, West Penn Hospital, 4800 Friendship Avenue, N1, Pittsburgh, PA 15224, USA Selective arthrodesis of the talonavicular joint (TNJ) and subtalar joint (STJ) through a single medial approach has been developed as an alternative surgical option to help avoid or diminish the incidence of complications sometimes encountered with triple arthrodesis. [8][9][10][11][12][13][14][15][16] Indications for this procedure include end-stage adult-acquired flatfoot (stage III or IV) when deformity is usually severe and nonreducible. The authors especially prefer this procedure with severe transverse plane deformity, where an Anteroposterior (AP) radiograph demonstrates severe subluxation or dislocation of the TNJ.…”
