Correlation Between Radiological Parameters and Functional Outcomes in Patients Older Than 60 Years of Age With Distal Radius Fracture.

The relationship between radiographic and functional outcomes is controversial in the elderly. The objective of this study is to determine whether there is a correlation between functional outcome and acceptable distal radius fracture (DRF) alignment in patients older than 60 years of age. This correlation study was carried out at the Central Metropolitan Health Service of Chile. A total of 180 patients diagnosed with extra-articular DRF, according to the AO classification, were prospectively recruited. Radiological parameters, including radial inclination, residual dorsal angulation, ulnar variance, and articular step-off, were evaluated to assess the results of orthopedic reduction. Functional outcome was assessed immediately following cast removal and again at the 6-month follow-up. The Disabilities of the Arm, Shoulder and Hand (DASH) and Patient-Rated Wrist Evaluation (PRWE) questionnaires were administered to assess upper extremity function, and the visual analog scale (VAS) was used to assess pain intensity. Only 68 patients (37.8%) showed acceptable DRF alignment. After cast removal, the correlations between alignment and the functional outcome measures were as follows: DASH 0.071 ( = .546), PRWE 0.03 ( = .823), and VAS 0.12 ( = .631). At the 6-month follow-up, the correlations between alignment and the functional outcome measures were as follows: DASH 0.029 ( = .768), PRWE 0.014 ( = .895), and VAS 0.09 ( = .614). There was no significant correlation between acceptable alignment according to radiological parameters and short- or medium-term functional outcome in patients older than 60 years with extra-articular DRF treated conservatively.
