The association between Radiological indices and functional outcomes in distal radius fracture

One of the factors affecting the prognosis of distal radius fracture is anatomical correction. Several studies conducted in connection with the reconstruction of anatomical and functional consequences, which have had conflicted results. This study has been designed and implemented aimed to investigate the relationship between radiological index (anatomical) after displaced distal radius fractures with function and clinical outcomes.

This is a retrospective cohort study to assess the association of radiological indices with clinical and functional outcomes of distal radius fractures. In this study, radiological indices, including the radius, volar tilt, tear drop angle, articular cavity depth and AP Distance were investigated. Pinch and grip strength were measured and Quick DASH questionnaire evaluated the performance.

Pain score significantly correlated with radial shortening (P=0,038), but it was not independent of treatment method. Patients’ satisfaction rate was significantly lower in patients with abnormal articular depth, independent of age and treatment method (P=0.004). Quick-DASH score significantly correlated with radial shortening and articular cavity depth, independent of treatment method and age (P=0.006). Percutaneous pinning associated significantly with less pain, less disability and more satisfaction (P<0.05).

Radial shortening, articular cavity depth had a correlation with the clinical and functional outcomes. While Some studies suggested radiological indices in the elderly is not necessarily have a correlation with functional outcomes, in this study correlation of radiologic indices with clinical and functional outcome was independent of age.
