Intrapelvic migration of a threaded Steinmann pin in Parkinson's disease

Intrapelvic migration of a threaded Steinmann pin complicated internal fixation of a displaced femoral neck fracture in an elderly man with untreated Parkinson's disease. Parkinsonian tremors may have contributed to this unusual complication. This case, in the light of a review of the literature, suggests that transfixation pins and wires should not be used in patients with Parkinson's disease. Endoprosthetic replacement combined with chemotherapy is better tolerated by femoral neck fractures in patients with Parkinsonism.
