Figure 2 The pressure ulcer repair process in the study group patient. A: A 5 cm diameter skin defect with purulent exudate was observed in the scapular region, surrounded by erythema and swelling; B: Postoperative view following the encouragement-based intervention (Watson’s theory), sequestrectomy of the scapula, synovectomy of the shoulder joint, and application of vacuum sealing drainage. The wound bed shows the growth of fresh granulation tissue. The ulcer area at this stage measured 7 cm × 7 cm; C: Postoperative view after surgical ulcer repair and capsular modification, showing the wound closed with absorbable sutures and one negative pressure drain in place.
