Editorial Comment on the Article by A.O. Farion et al. “Migration of a Kirschner Wire Into the Urinary Bladder: A Case Report”

The article “Migration of a Kirschner Wire into the Bladder: Case Report” describes a rather rare but serious complication after osteosynthesis of a medial femoral neck fracture performed with wires, that is a fatigue fracture of a Kirschner wire with migration of its proximal fragment into the bladder. It is stated in the commentary that such complications do occur and the results of their successful treatment have been published in the modern scientific literature. The author of the commentary draws attention to the tactical and organizational aspects of treating patients with femoral neck fractures related to this case. It is pointed out that there are standard replicable osteosynthesis techniques for fractures of a number of localizations that provide good clinical results. Proximal femur is one of these localizations, and the methods of surgical treatment of its fractures are described in details in current clinical guidelines. Possible reasons for the long-term persistence of pseudarthrosis of the femoral neck are also analyzed. Conclusions: when choosing a method of surgical treatment, it is necessary to follow the approved clinical guidelines to reduce the risks of nonunion of femoral neck fractures. Hip arthroplasty should be performed without delay in cases of fracture nonunion after osteosynthesis.
