Patient-Perceived Outcomes After Nonoperative Treatment Of Distal Radius Fracture In Older Adults

Malunion after distal radius fracture is common in older patients; however, whether patient-perceived outcomes are influenced by radiologic outcome is controversial. This study evaluated patient-perceived outcomes according to radiologic parameters in older patients who underwent nonoperative treatment. The records of 167 patients older than 55 years who had a distal radius fracture were reviewed. All fractures were treated nonoperatively, and average length of follow-up was 7 years. Outcomes were evaluated using numeric rating scales for pain and satisfaction, as well as Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores. Radiographs were evaluated for dorsal tilt, radial inclination, and ulnar variance. Fifty-one patients (30%) developed malunion. The pain numeric rating scale score was 0.8 for patients with malunion and 0.4 for patients with acceptable alignment; this difference was not statistically significant. The QuickDASH score was higher for patients with malunion (14.9 vs 11.1 for patients with acceptable alignment); however, this difference was not clinically meaningful. Satisfaction scores were lower for patients with malunion than for patients with acceptable alignment (80.8 vs 92.3). Patients with malunion stated they would choose surgery rather than a cast (13.3% vs 7.2%) if they developed another fracture; this difference was not statistically significant. The subanalysis according to radiologic parameters showed dorsal tilt and ulnar variance affected patient satisfaction but not other outcomes. This study indicated nonoperative treatment in older adults obtained acceptable patient-perceived outcomes despite residual deformity. However, patients whose radiologic parameter exceeded the tolerable range were less satisfied.
