[Fractures of the distal radius in patients over 70 years old: Volar plates or K-wires?].

In a growing elderly osteoporotic population, the management of distal radius fractures remains without consensus as to volar distal plate versus K-wires. The goal of this retrospective study was to evaluate these treatments in elderly people. In a series of 38 patients over 70 years, 21 were treated by a volar plate and 17 by percutaneous K-wire fixation. Follow-up was at least 6 months. Results were analyzed using the disabilities of the arm, shoulder and hand (DASH), patient-rated wrist evaluation (PRWE) and Herzberg score by an independent operator. Radiological parameters were radio-ulnar variance, radial inclination and palmar or dorsal tilt. Radio-ulnar variance was better for the plate group (-0.7mm versus -0.1mm in K-wires). Mean functional outcomes were good but there were more satisfied patients in the plate group (67% versus 39% for the K-wire group). Secondary displacements were frequent in both groups but more with K-wires (50% versus 37% in case of plates). Six articles about surgical treatment of elderly radius distal fractures were published up to 2009 showing similar results. However, they analyze only global mean scores. Volar plates give more stability and a higher rate of satisfaction, with similar results of wrist mobility and grasp strength. The main advantage of the plates is earlier return to daily activities.
