Stage-4 pressure ulcers are defined as ulcerations that violate the fascia and expose underlying bone, muscle, and tendon. Exposed bone is always colonized by bacteria, but this does not necessarily lead to osteomyelitis. The rates of osteomyelitis in exposed bone in stage-4 pressure ulcers range from 14% to 86%.There has been no evidence that the presence of osteomyelitis leads to higher complication rates following flap coverage. There has been no evidence that bone biopsy and preoperative treatment of osteomyelitis have any benefit before flap coverage.
四期压力性溃疡是指溃疡穿透筋膜，暴露深层的骨骼、肌肉和肌腱。暴露的骨骼总会被细菌定植，但这并不一定会导致骨髓炎。四期压力性溃疡中暴露骨骼的骨髓炎发生率为 14%至 86%。目前尚无证据表明骨髓炎的存在会导致皮瓣覆盖后并发症发生率升高。也没有证据表明在皮瓣覆盖前进行骨活检和骨髓炎的术前治疗有任何益处。
