IntroductionThe value of routine radiographs during follow-up after distal radius fractures is unclear. The aim of this study was to evaluate whether routine radiographs performed during the follow-up period in patients with a distal radius fracture influenced clinical decision making.MethodsThis retrospective cohort study included patients aged ≥18 years who were treated for a distal radius fracture at four hospitals in The Netherlands in 2012. Demographic and clinical and radiographic characteristics were collected from medical records.Results1042 patients were included. In 121 (14%) of the 841 radiographs, a clinical indication was reported. Treatment was affected by 22 (2.6%) radiographs, including 11 (1.5%) radiographs that were categorized as routine, 9 (1.2%) of which led to prolonged cast immobilization and 2 (0.2%) to surgery for conservatively treated patients.ConclusionAlthough it is common practice to take radiographs after distal radius fractures, the study results indicate that routine radiographs seldom affect treatment. This finding should be weighed against the high health care costs associated with these fractures. We hope that the results of our study will trigger the awareness among surgeons that in the current practice, many radiographs are taken on routine without influencing clinical decision making and can probably be omitted.Level of evidenceLevel III.

Currently, the routine use of radiographs for uncomplicated ankle fractures represents good clinical practice. However, radiographs are associated with waiting time, radiation exposure, and costs. Studies have suggested that radiographs seldom alter the treatment strategy if no clinical indication for the imaging study was present. The objective of the present study was to evaluate the effect of routine radiographs on the treatment strategy during the follow-up period of ankle fractures. All patients aged ≥18 years, who had visited 1 of the participating clinics with an eligible ankle fracture in 2012 and with complete follow-up data were included. The data were retrospectively analyzed. The sociodemographic and clinical characteristics and the number of, and indications for, the radiographs taken were collected from the medical records of the participating clinics. We assessed the changes in treatment strategy according to the radiographic findings. In 528 patients with an ankle fracture, 1174 radiographs were performed during the follow-up period. Of these radiographs, 936 (79.7%) were considered routine. Of the routine radiographs taken during the follow-up period, only 11 (1.2 %) resulted in changes to the treatment strategy. Although it is common practice to take radiographs routinely during the follow-up period for ankle fractures, the results from the present study suggest that routine radiographs seldom alter the treatment strategy. This limited clinical relevance should be weighed against the health care costs and radiation exposure associated with the use of routine radiographs. For a definitive recommendation, however, the results of our study should be confirmed by a prospective trial, which we are currently conducting.

BackgroundExtremity fractures such as wrist and ankle fractures are a common and costly healthcare problem. The management of these fractures depends on fracture type and loss of congruity of the joint, resulting in cast immobilization or operative treatment. Loss of congruity or displacement leading to uneven joint loading, osteoarthritis and an increased probability of a poor functional outcome should be identified within the first 2 weeks post-trauma, based upon radiographs to determine optimal treatment. After this period, routine radiographs are scheduled for monitoring the bone-healing process. Current protocols describe imaging at 1, 2, 6 and 12 weeks post-trauma. However, it is questionable whether routine radiography following the initial follow-up ( 2-weeks post-trauma) is cost effective.The aim of this study is to determine whether a modification of the radiographic follow-up protocol can be conducted with no worse outcome and less cost than the current standard of care for patients with a wrist or ankle fracture.Methods/designIn a multicenter randomized controlled trial, 697 patients aged 18 years or older will be included: 385 wrist fracture- and 312 ankle fracture patients. Patients will be randomized into two groups: Group 1 receives usual care, consisting of radiographs 1, 2, 6 and 12 weeks post-trauma; Group 2 receives radiographs beyond the initial follow-up only when clinically indicated. The primary outcome is the overall extremity-specific function. For wrist fractures, this includes the Disabilities of the Arm, Shoulder and Hand Score; for the ankle fractures, this includes the Olerud and Molander ankle score. Secondary outcomes include: healthcare cost, the specific function measured with the Patient Rated Wrist and Hand Evaluation for wrist fractures and American Academy of Orthopaedic Surgeons foot and ankle questionnaire for ankle fractures, pain-intensity, health-related quality of life, self-perceived recovery, and complications. Both groups will be monitored at 1, 2, and 6 weeks and 3, 6, and 12 months.DiscussionThis study will provide data on (cost) effectiveness of routine radiography in the follow-up of wrist and ankle fractures, and could pave the way for a change in (inter)national protocols.Trial registrationNetherlands Trial Register NTR4610, registration date 22 June 2014.
