Distal Radius Extra-Articular Fractures: The Impact of Anatomical Alignment on Patient’s Perceived Outcome (A Single Center Experience)

Purpose: The effects of the anatomical alignment of distal radial extra-articular fractures on the patient's perceived outcome have been drawing much attention recently, and much controversy exists in the literature. The primary purpose of this study was to explore the relationship between the radiological parameters of reduction (radial inclination, radial length, and radial tilt) and the patient's perceived functional outcome, which was quantified using the DASH questionnaire. Methods: The study included one hundred twenty-four patients with distal radial extra-articular fractures managed by closed reduction and casting. Their radiological (anatomical) outcome was determined by measuring the radial inclination, tilt, and length. Subjective functional outcome was quantified using the DASH score, calculated from the Arabic-translated DASH questionnaire at three months and six months after cast removal. Results: the mean DASH score was 31.56 SD± 9.1 at three months and 29 SD± 3.89 at six months, and the acceptable radiological results for radial tilt, radial inclination, and radial length (according to McDermid's criteria for acceptable reduction) were 77.4%, 88.7% and 74.4%, respectively. There was a significant linear correlation between two radiological parameters (radial tilt and radial length) and the DASH score at three-month follow-up, which was more profound among patients under 70 years old and with diabetes mellitus. At the six-month follow-up, there was no significant relationship between the radiological parameters and the DASH score. Conclusion: This study confirmed that radiological outcome affects the early patient-perceived outcome, with a more significant effect among patients under 70 and diabetics. Nonetheless, over time, there will be no significant relationship between the quality of reduction and patients' perceived outcomes. And this phenomenon requires further investigation.
