Incidence for volar locking plate removal following distal radius fracture surgery.

INTRODUCTION

Distal radius fracture is the most common fracture in adults. The most common treatment for distal radius fracture is non-operative cast immobilization, although there are injuries that require surgical treatment. During the past decade, studies have reported a large increase in the surgical treatment of distal radius fractures with open reduction and internal fixation using volar locking plates. The aim of this study was to investigate the incidence and trends for plate removal after plate fixation of distal radius fractures.

MATERIALS AND METHODS

The study covered all patients 18 years of age and older who had a surgically treated distal radius fracture with open reduction and internal fixation in Finland between 1998 and 2016. Patient data were obtained from the Finnish National Hospital Discharge Register. The association between increased number of platings and plate removals was examined by calculating the removal rates. The study population comprises all patients on a national level, and therefore we did not use statistical testing to analyze the data.

RESULTS

A total of 18,298 patients had surgically treated distal radius fracture with volar plate in Finland during the 19-year study period from January 1, 1998 to December 31, 2016. The number of plate removal operations over the same time period was 2560. The removal rates decreased from over 20% in 1998 to less than 12% in 2016. The mean time period between plating and plate removal operations was 367 days. Most of the plate removals (n = 2235; 87.3%) were conducted during the first 2 years after plating.

CONCLUSION

Plate removals have not increased as rapidly as plating operations. The removal rate has declined markedly during the last decade. Nowadays, approximately 11% of distal radius plates are removed.
