Functional Outcome of Intra-articular Fracture of Distal Radius Using External Fixator

Abstract

Introduction: Distal radius fractures commonly occur in the upper limb after highvelocity trauma and can be managed by several methods. External fixation using the principle of ligamentotaxis aims to restore radial length, volar tilt, and radial inclination. This study assesses outcomes of ligamentotaxis-based external fixation for intraarticular distal radius fractures.

Materials and Methods: In this prospective interventional study, 50 patients with distal radius fractures were treated with external fixation. Included were patients aged 15–79 years, with Frykman types III–VIII fractures, failed closed reduction with casting, Gustilo–Anderson grade I–II open fractures, and those fit for surgery. Outcomes were measured by the Demerit Point System of Gartland and Werley, modified by Sarmiento.

Results: Among the 50 patients, most were male and the mean age was 40.28 years (SD ±13.64). Anatomical outcomes were rated excellent to good in 80% of cases. Functional outcomes were excellent to good in 64% of patients. A small number experienced persistent pain.

Conclusion: External fixation employing ligamentotaxis is a suitable option for managing intraarticular distal radius fractures, yielding satisfactory anatomical and functional outcomes in most patients.
