Background:
The results for nonunion surgery usually have been judged in terms of bony union, time to union, infection rate, range of motion for the adjacent joints, and muscle strength. The goal of this study was to assess the improvement of patient-oriented physical and mental functional outcomes.
Methods:
The functional status of 23 patients with nonunion of the lower extremity was assessed using the Short-Form Health Survey (SF-36) questionnaire. The SF-36 subscores were compared with preoperative values and with the average values for the U.S. population.
Results:
Of the 23 patients, 21 healed. The functional status for nonunions of the lower extremity was greatly improved 1 year after operative intervention in this study. Nevertheless, the results show that it did not reach the level of the average U.S. population.
Conclusion:
The results of this study can be used to guide patients' expectations regarding the functional outcome of treatment for a nonunion of the lower extremity.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
