Kirschner wires are frequently employed in orthopedic procedures. While most complications are minor, rare instances of distant pin migration can occur. Such migration is more prevalent in the shoulder region but has been reported elsewhere.
A 50-year-old Persian male with a right femoral neck fracture (Garden type IV) underwent closed reduction and internal fixation with three cannulated screws. During the procedure, a guide pin broke and remained lodged. Follow-up radiographs revealed the migrated pin in the patient's chest wall near the 11th rib, necessitating surgical removal via thoracotomy.
This case underscores the potential for orthopedic implant migration. While often associated with smaller pins, the risk exists for all sizes. The timeframe for diagnosis varies significantly and in some cases it can be asymptomatic and discovered incidentally.
克氏针常用于骨科手术。虽然大多数并发症都比较轻微，但偶尔会出现远处的针迁移。这种迁移在肩部更为常见，但也有其他部位的报道。
一名 50 岁的波斯男性，右侧股骨颈骨折（Garden 类型 IV），行闭合复位和三根空心螺钉内固定术。手术过程中，导针断裂并残留。随访 X 线片显示患者 11 肋附近的胸壁有迁移的针，需要通过开胸手术取出。
本例强调了骨科植入物迁移的可能性。虽然通常与较小的针相关，但所有尺寸的针都存在风险。诊断的时间框架差异很大，在某些情况下可能无症状且偶然发现。
