Outcomes and cost of care for patients with distal radius fractures

Abstract

This study was designed to evaluate treatment patterns in open treatment and percutaneous fixation of distal radius fractures, compare morbidity rates for the 2 types of treatment, and compare costs associated with the procedure and treatment of complications up to 1 year after surgery. From a 5% sample of nationwide Medicare claims records (1997-2009), patients with distal radius fractures were identified with International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM), codes. Patients who underwent percutaneous fixation and open treatment were tracked with appropriate Current Procedural Terminology codes. Complications were identified at 3 and 12 months. Medicare charges and payments associated with the treatment groups were compiled from the claims data. The rate of surgical treatment increased from 44.7 to 82.0 surgeries per 100,000 persons (+83.0%) over the study period. A total of 9343 procedures met the inclusion criteria between 1998 and 2008. The proportion of open treatment procedures increased from 25.5% in 1998 to 73.4% in 2008. Percutaneous fixation was associated with lower adjusted risk of carpal tunnel syndrome and release and mononeuritis at 3 and 12 months. The percutaneous fixation group had lower adjusted risk of malunion/nonunion at 3 months and tendon rupture at 12 months. Average charges were lower in the percutaneous fixation group for the index operation as well as for treatment of morbidities at 3 and 12 months. The operative fixation rate for distal radius fractures in the Medicare population continues to rise, with a significant trend toward open fixation. Charges and payments associated with open treatment are significantly higher than those for percutaneous fixation.
