Are external fixators as effective as volar plates in multi-fragmented radius distal intra-articular fractures (AO type C)?

Abstract

Introduction: This study aimed to compare the radiological and clinical results of VP and EF applications in multi-fragmented radius distal intra-articular fractures (AO type C) in our clinic.

Methods: We retrospectively analysed 80 patients who underwent surgery for radius distal fracture (AO type C) between 2014 and 2020. Group 1 comprised patients who were treated with VP, and Group 2 comprised patients who were treated with EF. Radiological evaluation was performed by measuring radial inclination, radial length, volar tilt, intra-articular step-off and ulnar variance by two-way radiography. The clinical findings were evaluated using the Gartland and Werley scoring system, and complications were noted.

Results: There were no statistically significant differences between the two groups in terms of age, gender, side, fracture subtypes and follow-up time (p > 0.05). There were no statistically significant differences between the two groups in radiological parameters (based on cut-off values) (p > 0.05). The clinical evaluation did not reveal a statistically significant difference between the two groups (p = 0.613).

Conclusion: EF is as successful as VP in providing radiological cut-off values. EF treatment can be used as an effective and safe alternative method for multi-fragmented radius distal intra-articular fractures.
