Abstract：
Necrotizing soft tissue infections (NSTIs), characterized by extensive soft tissue destruction, are rare but life-threatening. We present a case of a NSTI in a healthy 65-year-old woman following a closed distal radius fracture. The patient presented with severe pain, fever, and lethargy 4 days after her index injury, with physical examination of the right upper limb revealing erythema and swelling to the mid-humeral level and blisters of the fingers and hand. Multiple surgical debridements were required to control the infection, which was caused by Streptococcus pyogenes. This case highlights the rapid progression and devastating consequences of NSTI, which can occur even in the setting of closed injuries in patients without comorbidities. Prompt diagnosis, early surgical intervention, and appropriate antimicrobial therapy are crucial in managing this pathology.Level of Evidence: Level 5.
摘要：
坏死性软组织感染（NSTIs），以广泛的软组织破坏为特征，罕见但有生命危险.我们介绍了一名健康的65岁女性在闭合性桡骨远端骨折后发生NSTI的情况。患者出现剧烈疼痛，发烧,在她受伤4天后昏昏欲睡，对右上肢进行身体检查，发现红斑和肱骨中部肿胀，手指和手起泡。需要多次手术清创术来控制感染，是由化脓性链球菌引起的.这个案例凸显了NSTI的快速进展和破坏性后果，即使在没有合并症的患者的闭合性损伤中也可能发生。及时诊断,早期手术干预，和适当的抗菌治疗是至关重要的管理这种病理。证据等级：5级。
