Abstract
Introduction: 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.
Case presentation: 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.
Conclusion: 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.
导言：骨科手术中经常使用克氏针。虽然大多数并发症都很轻微，但也有极少数情况下会发生远处针移位。这种移位在肩部区域更为常见，但在其他部位也有报道：一名 50 岁的波斯男性因右侧股骨颈骨折（Garden IV 型）接受了闭合复位术，并用三枚套管螺钉进行了内固定。在手术过程中，一枚导针断裂并被卡住。随访X光片显示，移位的导针位于患者胸壁第11根肋骨附近，因此必须通过开胸手术将其取出：本病例强调了骨科植入物移位的可能性。结论：本病例强调了骨科植入物移位的可能性，虽然通常与较小的植入物有关，但所有尺寸的植入物都存在移位风险。诊断的时间范围差异很大，在某些情况下，可能没有症状，只是偶然发现。
期刊介绍：
JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
