Volar locking plate vs epibloc system for distal radius fractures in the elderly.

Purpose: To compare clinical outcomes of ORIF with volar locking plates and the Epibloc system (ES) in the treatment of distal radius fractures (DRFs) in patients aged over 65 years.
Methods: We retrospectively examined a consecutive series of 100 patients with intra-articular or extra-articular DRF who were admitted to our Department of Orthopaedics and Traumatology between January 2007 and January 2013. Fifty patients were treated using the Epibloc System; and the other 50 patients using ORIF with volar locking plates. In all patients, functional evaluation (wrist range of motion [ROM], grip strength and Disability of the Arm, Shoulder and Hand [DASH] Score) and radiographic assessment (radial inclination, volar tilt, ulnar variance and articular congruity) were performed at 2 and 6 weeks, and 3, 6 and 12 months postoperatively; then every 12 months thereafter.
Results: ORIF with volar locking plates was associated with better outcome than ES in the intra-articular and extra-articular DRF groups, generating higher average ROM, DASH and visual analogue scale (VAS) scores. Grip strength mean values, however, were quantified over the minimum level for a functional wrist (>60%) in both groups. There were no differences between the two techniques in X-ray parameters, and no further correlation was found with functional outcome and ROM.
Conclusions: In a low-functioning patient with multiple medical comorbidities, minimally-invasive surgery with the ES is a safe option, enables early mobilisation of the wrist and is likely to produce acceptable clinical outcomes.
