| Abstract |
Purpose
The purpose of the study was to analyze the radiologic and clinical outcomes of volar locking plate leveraging technique comparing to conventional technique and to prove the effect of volar locking plate leveraging technique on restoring volar tilt of distal radius fractures.
Methods
From January 2011 to December 2015, 196 patients (50 males and 146 females) who underwent operative treatment of distal radius fracture met the inclusion criteria and retrospectively analyzed. We defined group 1 (n=93, 23 males and 70 females) as patients who were operated by conventional method, and group 2 (n=103, 27 male and 76 females) as patients who were operated by volar locking plate leveraging technique. Postoperative radiographic parameters including radial inclination, radial length, and volar tilt were measured as radiologic outcomes and range of motion, pain visual analogue scale, grip strength, shortened disabilities of arm, shoulder and hand questionnaire were measured as clinical outcomes.
Results
Postoperative radial inclination, radial length, and volar tilt in group 1 was 24.22°, 12.02 mm, and 9.31°, in group 2 was 25.64°, 12.40 mm, and 11.48°. There was statistically significant difference in postoperative volar tilt (p=0.008). There were no statistic differences in other radiologic parameters and clinical outcomes.
Conclusion
Volar locking plate leveraging technique is reliable and predictable technique for restoration of anatomical parameters of distal radius fracture, especially volar tilt. |
