Wrist hemiarthroplasty for irreparable DRF in the elderly.

Abstract

The authors update their results of wrist hemiarthroplasty for irreparable distal radius fracture in the elderly, at a minimum of 2-year follow-up. Between 2011 and 2018, 25 consecutive independent elderly patients (24 female, 27 wrists) were treated with wrist hemiarthroplasty for distal radius fracture at a single institution. The average age was 77 years (range 65-88). They all were independent at home. A total of 19 wrists were treated at the acute stage, and 8 secondary procedures. The average follow-up was 32 months (range 24-44). There was no dislocation, loosening, infection nor removal of the implants. We observed 3 CRPS. At final follow-up, the average VAS pain was 1/10, mean forearm pronation/supination arc was 150°, and mean active flexion-extension arc was 60°. Average wrist extension was 36°. Mean grip strength was 68% of contralateral side. Mean Lyon wrist score was 74%. Mean Quick DASH score was 26%, and mean PRWE score was 25%. Our data suggest that treatment of acute irreparable distal radius fracture in the independent elderly patient with a bone-preserving primary wrist hemiarthroplasty may be a viable option. Longer-term follow-up are needed to confirm these preliminary data.
