Intrapelvic migration of Kirschner wires causing bladder perforation without peritonitis: A case report.

Kirschner wire (K-wire) migration is a rare but potentially serious complication of orthopedic fixation. We report a 49-year-old man presenting with chronic lower abdominal pain two years after femoral neck fracture fixation. Computed tomography revealed multiple migrated K-wires within the pelvis, including one perforating the urinary bladder. Exploratory laparotomy confirmed both intra- and extraperitoneal bladder perforations without peritonitis or urine leakage. All wires were successfully removed, and the bladder perforations were repaired with suprapubic cystectomy. The patient recovered uneventfully. This case highlights the importance of long-term follow-up and timely removal of K-wires to prevent serious complications.
