突然发生的固定会在骨关节上产生意外的外力，是压疮的潜在原因。在这里，我们报告两例深压疮急性单关节炎患者的结果焦磷酸钙（CPP）晶体沉积（假性痛风）。患者为80岁的女性，可自行进行日常生活活动。他们在住在自己家里时患上了压疮。由于已知急性CPP结晶性关节炎在相对健康的老年患者中发生，因此患者和护理人员预计不会突然发生固定。此外，较大的关节优先参与急性CPP晶体关节炎，导致患者无法改变自己的立场。因此，急性CPP结晶性关节炎应被认为是压疮的潜在病因。该病例报告进一步强调了“疾病特异性意外外力”的新概念，这有利于预防压疮。
Sudden‐onset immobilisation generates unexpected external forces over bony prominences and is a potential cause of pressure ulcers. Here, we report two cases of deep pressure ulcers in patients with acute monoarthritis as a result of calcium pyrophosphate (CPP) crystal deposition (pseudogout). The patients were women in their 80 who could perform activities of daily living by themselves. They developed pressure ulcers while living in their own home. Because acute CPP crystal arthritis is known to develop in relatively healthy elderly patients, patients and caregivers do not expect sudden‐onset immobilisation. In addition, larger joints are preferentially involved in acute CPP crystal arthritis, leading to the inability of patients to change positions themselves. Therefore, acute CPP crystal arthritis should be recognised as a potential causal disease for pressure ulcers. This case report further highlights a new concept of “disease‐specific unexpected external force”, which is beneficial for the prevention of pressure ulcers.
