Interference screws are used as back-up fixation in anterior cruciate ligament reconstructions. Historically these were composed of metal, but recently surgeons have switched to using bioabsorbable screws as they cause less symptoms and are biomedically advantageous. Usually these screws are absorbed by the body within one to two years after surgery.
A 32-year-old male presented with aseptic extrusion of his intact tibial bioabsorbable interference screw eight years following successful anterior cruciate ligament reconstruction.
Patient underwent laboratory evaluation and magnetic resonance imaging to rule out infection as an underlying cause. He went on to heal the wound without complication.
Late aseptic extrusion of tibial interference screw can occur; however, infectious etiologies should be carefully ruled out.
在膝关节前交叉韧带重建手术中，挤压螺钉用作辅助固定。过去这些螺钉由金属制成，但最近外科医生已转而使用生物可吸收螺钉，因为它们引起的症状较少且具有生物医学优势。通常这些螺钉在术后一到两年内会被身体吸收。
一名32岁男性在成功进行前交叉韧带重建手术八年后，出现完整的胫骨生物可吸收挤压螺钉无菌性挤出。
患者接受了实验室评估和磁共振成像检查，以排除感染作为潜在病因。他随后伤口愈合，未出现并发症。
胫骨挤压螺钉可能会出现晚期无菌性挤出；然而，应仔细排除感染性病因。
