Importance:
Casting is recommended for adults older than 65 years with distal radius fractures (DRFs) because similar long-term outcomes are achieved regardless of treatment. However, physiologically younger adults could benefit from operative DRF management despite advanced chronologic age.
Objective:
To examine how chronologic age compares with measures of physiologic age in DRF treatment recovery.
Design, Setting, And Participants:
This retrospective secondary analysis of the Wrist and Radius Injury Surgical Trial (WRIST) was performed from May 1 to August 31, 2022. WRIST was a 24-center randomized clinical trial that enrolled participants older than 60 years with unstable DRFs from April 1, 2012, to December 31, 2016.
Interventions:
Participants selected casting or surgery. Patients who selected surgery were randomly assigned to volar lock plating, percutaneous pinning, or external fixation. Participants were stratified by chronologic age, number of comorbidities, and activity status.
Main Outcomes And Measures:
The primary outcome was Michigan Hand Outcomes Questionnaire (MHQ) score assessed at 6 weeks, 3 months, 6 months, and 1 year. Partial correlation (PC) analysis adjusted for confounding.
Results:
The final cohort consisted of 293 participants (mean [SD] age, 71.1 [8.89] years; 255 [87%] female; 247 [85%] White), with 109 receiving casting and 184 receiving surgery. Increased chronologic age was associated with increased MHQ scores in the surgery group at all time points but decreased MHQ scores in the casting group at 12 months (mean [SD] score, -0.46 [0.21]; P = .03). High activity was associated with improved MHQ scores in the surgical cohort at 6 weeks (mean [SD] score, 12.21 [5.18]; PC = 0.27; P = .02) and 12 months (mean [SD] score, 13.25 [5.77]; PC = 0.17; P = .02). Comorbidities were associated with decreased MHQ scores at all time points in the casting group. Clinically significant differences in MHQ scores were associated with low physical activity, 4 or more comorbidities, or increased age by 15 years.
Conclusions And Relevance:
In this retrospective secondary analysis of WRIST, chronologic age was not associated with functional demand. These findings suggest that physicians should counsel active older adults with few comorbidities on earlier return to daily activities after surgery compared with casting.

01:27Fractures: Bone Repair
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...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
