Abstract
Introduction
The distal radius is the most frequently fractured bone in the forearm with an annual fracture incidence in the UK of about 9–37 in 10,000. Restoration of normal anatomy is an important factor that dictates the final functional outcome. A number of operative options are available, including Kirschner wiring, bridging or non-bridging external fixation and open reduction and internal fixation by means of dorsal, radial or volar plates. We designed this study to analyse the clinical and radiological outcome of distal radial fracture fixation using volar plating.
Materials/Methods
Thirty-seven patients with distal radius fractures undergoing open reduction and internal fixation using volar plates were included. Tilt of the fractured distal radial fragment was recorded from the initial radiograph and classification of fractures was done using the Orthopaedic Trauma Association system. The QuickDASH questionnaire was used for evaluation of symptomatic and functional outcome six months to one year after surgery. The radiological outcome was assessed using measurements of radial inclination, ulnar variance and volar tilt. Of the thirty-seven patients, 13 were male and 24 were female. The mean age was 55.6 years (range 18–87 years). According to the AO classification, there were 8 cases each of C2 and C3 fractures, 6 cases of C1 fractures and 3 cases each of class A2, A3, B1 and B3 fractures. There were 2 patients with class B2 fracture.
Results
Post-operatively, the average restoration of volar tilt was 6.47 degrees (range −12.4 to 20.3 degrees). Mean restoration of radial inclination was 23 degrees (range 12.5 to 30.0 degrees). Ulnar variance on average was 0.09 mm (range −5.0–6.7mm). The mean QuickDASH score was 9.8.
Conclusion
The results of this study indicate that fixation of displaced intra- and extra-articular distal radial fractures is achieved satisfactorily with restoration of both normal anatomy and function using volar plates.
