Reasons for Implant Removal after Distal Radius Fractures

With new low profile locked volar plate designs for distal radius fractures, soft tissue complications are uncommon. However, there are still patients who request to have their implants removed. In this study, we retrospectively reviewed the reasons for this.

We reviewed the hospital operative records of patients who had operative fixation of wrist fractures between November 2008 and May 2009. We examined the clinical records of these patients in order to ascertain if there was a difference in patient demographics between those who eventually had their implants removed and those who had their implants retained. We also noted down the reasons for removal of implants.

In the period of study, 165 patients had operative fixation of their distal radius fractures, of which 44 (26.7%) had had their implants eventually removed. These patients tended to be younger (mean age of 37.1 years compared to 45.5 years in those who retained their implants). We also found a correlation between removal of implants and the presence of ulnar implants, as well as hand dominance. Reasons for implant removal were symptomatic irritation/implant prominence (15), joint stiffness requiring arthrolysis (6), infection (2), malunion (2), and patients who did not have a clinical reason (19).

Our results suggest the involvement of other psychosocial factors, such as cultural attitudes towards the presence of implants within the body. In light of our results, we also suggest that ulnar styloid fractures be treated non-operatively.
