No decay in outcomes at a mean 8 years following surgical treatment for aseptic fracture nonunion

•Patients successfully treated for an aseptic fracture nonunion recover self reported baseline function at one year, and this recovery is maintained throughout longterm follow up.•Complications related to aseptic fracture nonunion surgical repair are not seen beyond one year following surgical repair.•Patient reported pain and associated joint range of motion also remained stable over time. : The purpose of this study is to compare medium to long term patient reported outcomes to one-year data for patients treated surgically for an aseptic fracture nonunion. : 305 patients surgically treated for a fracture-nonunion were prospectively followed. Data collected included pain scores measured by the Visual Analog Scale (VAS), clinical outcomes assessed by the Short Musculoskeletal Functional Assessment (SMFA), and range of motion. 75% of patients in this study had lower extremity fracture nonunions and 25% had upper extremity fracture nonunions. Femur fracture nonunions were the most common. Data at latest follow-up was compared to one-year follow-up using the independent t-test. : Sixty-two patients were available for follow-up data at an average of eight years. There were no differences in patient reported outcomes between one and eight years according to the standardized total SMFA (p = 0.982), functional index SMFA (p = 0.186), bothersome index SMFA (p = 0.396), activity index SMFA (p = 0.788), emotional index SMFA (p = 0.923), or mobility index SMFA (p = 0.649). There was also no difference in reported pain (p = 0.534). Range of motion data was collected for patients who followed up in clinic for an average of eight years after their surgical treatment. 58% of these patients reported a slight increase in range of motion at an average of eight years. : Patient functional outcomes, range of motion, and reported pain all normalize after one year following surgical treatment for fracture nonunion and do not change significantly at an average of eight years. Surgeons can feel confident in counseling patients that their results will last and they do not need to follow up beyond one year, barring pain or other complications. : Level IV
