Assessment of variable angle volar locking plate as a tool for treatment of unstable intra articular distal radius fractures

Abstract

Background: Distal radius fractures are one of the common fractures, more so in geriatric age group. Functional outcome is of paramount importance, thus efficacy of newer implant systems remains to be evaluated in terms of patient satisfaction and functional results. Methods: This prospective study involves 35 patients, all having unstable distal radius fractures and treated with Open reduction and Internal Fixation using Variable Angle Locking Plate system. The mean age of patients was 54 years. The PRHWE score was used for evaluation, and radiological assessment as a tool for fracture healing and union. At the time of final evaluation outcome was assessed as per Gartland and Werley scoring system. Results: Average Range of motion as achieved in the present study was recorded as Pronation 79.35 Degree, Supination 82.32 Degree, Palmar flexion 59 Degree, Dorsiflexion 61.8 Degree & Ulnar deviation 3.30 Degree. Radiological parameters as measured at final evaluation were: Volar tilt 5.55 Degree, Radial inclination 18 Degree & Ulnar variance -0.52 mm. At 6 months mean PRHWE score was 6.85 (SD±2.87). At 12 months mean PRHWE score was 4.52 (SD±2.30) Out of 35 patients, 32 patients had final score between 0 to 5 which was statistically significant (P
