Introduction:
The association between body mass index (BMI) and functional outcomes is unknown in elderly individuals with distal radius fracture (DRF).
Objective:
The aim of this study is to evaluate if there is association between BMI and functional outcomes in patients older than 60 years with DRF treated conservatively.
Materials And Methods:
A prospective observational study was performed. A total of 228 patients with extra-articular DRF were prospectively recruited. All patients were categorized by their BMI as normal, overweight, or obese. Functional outcomes were assessed after cast removal and at 1-year follow-up. The Disabilities of the Arm, Shoulder and Hand Outcome Measure (DASH), and Patient-Rated Wrist Evaluation (PRWE) questionnaires were used to assess upper limb and wrist/hand function, respectively, while the Jamar Dynamometer was used to assess grip strength.
Results:
Of the total number of patients, 184 were female (80.7%), 87 were overweight (38.2%), and 111 were obese (48.7%). After cast removal, the correlations between BMI and functional outcomes were DASH 0.06 (p = 0.578), PRWE 0.04 (p = 0.692), and grip strength - 0.02 (p = 0.763). At 1-year follow-up, the correlations were DASH 0.55 (p = 0.036), PRWE 0.32 (p = 0.041), and grip strength - 0.21 (p = 0.043).
Conclusion:
This study suggests that at 1-year follow-up, there was a low-to-moderate association between BMI and poor functional outcomes in elderly patients with extra-articular DRF treated conservatively.
Level Of Evidence:
Level IV, observational prospective study.
