Distant migration of a broken guide pin following femoral neck fixation: a case report.

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. [ABSTRACT FROM AUTHOR]
