Images displaying the procedural method of proximal row carpectomy with interposition arthroplasty using capsular and dermal allografts. (A) The dorsal capsule (black arrow), which is based proximally, is lifted from the carpometacarpal joints to the distal articular boundary of the radius. (B) Four all-suture anchors were inserted into the articular margin of the radius. (C) Dermal allograft interposition (arrowheads) was carried out at each corner using four suture anchors. Subsequently, dorsal capsular interposition arthroplasty (arrow) was performed
