Nonunion after a periprosthetic femoral fracture associated with total hip arthroplasty occurs rarely.
There is little information, to our knowledge, regarding the prevalence of this complication, its treatment, and the functional outcomes of treatment.
The purpose of this study was to identify the patterns and frequency of nonunions of femoral fractures around total hip prostheses and to evaluate the results and problems associated with treatment of this complication in a consecutive series of patients.
The study included twenty-three non-unions of periprosthetic femoral fractures in twenty-three patients with an average age of fifty-five years (range, twenty-two to eighty-five years) at the time of the initiation of treatment of the nonunion.
Thirteen of the fractures occurred during or after a primary total hip arthroplasty, and ten occurred during or after a revision total hip arthroplasty.
According to the classification system of Duncan and Masri, there were six B1 fractures (associated with a well fixed prosthesis), seven B2 fractures (associated with a loose stem), and ten B3 fractures (associated with very poor proximal bone).
Ten patients were managed with revision to a long-stem prosthesis.
Six patients had revision to a proximal femoral replacement prosthesis. (...)
