Are the Clinical Results of Locking Plate Fixation for Distal Radius Fractures Inferior in Patients over 80 Years of Age? A Multicentre (TRON Group) Study

Introduction With the aging of the population, the proportion of distal radius fracture patients who are > 80 years of age is increasing. In this study, we compared the postoperative clinical and radiographic outcomes between super-elderly patients (age: >= 80 years) and middle-elderly (age: 65-79 years) who were treated with volar locking plate (VLP) fixation for distal radius fractures. Patients and Methods Patients of > 65 years of age with distal radius fractures treated by VLP fixation between 2015 and 2019, and who were followed for at least 6 months after surgery were included in our database (named TRON). Patients with open fractures, multiple-trauma, or who received fixation with implants other than a VLP were excluded. We evaluated postoperative complications, Mayo wrist score (MWS), and radiographic outcomes. Results We identified 589 patients in this study; 452 were 65-79 years of age (Group A) and 137 were & GE; 80 years of age (Group B). After propensity score matching, we evaluated 309 patients in Group A and 103 patients in Group B. The mean follow-up period was 10.7 +/- 4.6 months. Twenty-eight patients (9.1%) in Group A and 5 patients in Group B (4.9%) experienced post-operative complications (non-significant: p = 0.212). The postoperative MWS at 1, 3, and 6 months, respectively, was 65.4 +/- 11.7, 75.2 +/- 11.0, and 79.6 +/- 10.5 in Group A and 67.1 +/- 9.61, 75.7 +/- 10.7, and 80.6 +/- 9.7 in Group B (non-significant: p = 0.418, 0.893, 0.452, respectively). The differences in volar tilt, radial inclination, ulnar variance between the postoperative and last follow-up radiographs did not differ between the two groups to a statistically significant extent (p = 0.053, 0.437, 0.529, respectively). Conclusion Our study showed that the clinical and radiographic outcomes of distal radius fractures treated with VLP in super-elderly patients were comparable to those in middle-elderly patients.
