Routine imaging after operatively repaired distal radius and scaphoid fractures: a survey of hand surgeons

The value of routine radiographic follow up in the postoperative management of canine medial patellar luxation

OBJECTIVE

To determine the influence of radiographic examination on the recommendations made at the time of planned re-evaluation of dogs after medial patellar luxation (MPL) surgery.

STUDY DESIGN

Retrospective multi-institutional case series.

ANIMALS

Client-owned dogs (N = 825) that underwent MPL surgery.

METHODS

Records of 10 referral institutions were searched for dogs that had been treated surgically for unilateral MPL and underwent a planned follow-up visit, including radiographs. The frequency of, and reasons for, changes in further recovery recommendations were investigated.

RESULTS

Follow up was performed at a median of 6 (range, 4-20) weeks postoperatively. Isolated radiographic abnormalities were identified in 3.3% (27/825) of dogs following MPL surgery and led to a change in recommendations in 3% (13/432) of dogs that were presented without owner or clinician concerns. Lameness, administration of analgesia at follow up, and history of unplanned visits prior to routine re-examination were associated with a change in postoperative plan (P < .001). In the absence of owner and clinician concerns, the odds of having a change in convalescence plans were not different, whether or not isolated radiographic abnormalities were present (P = .641).

CONCLUSION

Routine radiographs at follow up did not influence postoperative management of most dogs after MPL surgery in the absence of abnormalities on clinical history or orthopedic examination.

CLINICAL SIGNIFICANCE

Dogs that were presented for routine follow up after unilateral MPL surgery without owner concerns, lameness, analgesic treatment or a history of unplanned visits, and for which examination by a surgical specialist was unremarkable, were unlikely to benefit from radiographs.

Routine x-rays after the osteosynthesis of distal radius and ankle fractures—a prospective randomized controlled trial on the necessity of routine imaging

BACKGROUND

The utility of routine x-rays after the osteosynthesis of distal radius fractures and ankle fractures is questionable. We performed a trial to determine whether such x-rays are justified in patients who have undergone standardized imaging with C-arm fluoroscopy during surgery.

METHODS

Patients requiring surgery for a distal radius fracture or an ankle fracture were candidates for inclusion in this prospective, randomized, controlled, non-blinded trial. Standardized intraoperative images were obtained with C-arm fluoroscopy and stored at the end of the operation. The next day, patients in the control group underwent imaging with a standard postoperative x-ray, while those in the intervention group did not. The primary endpoint was a change in the treatment plan, defined as additional imaging or a second operation. The secondary endpoints included the range of motion, pain as rated on the Visual Analog Scale, and a functional outcome analysis (PRWE/FAOS).

RESULTS

316 patients were included in the trial (163 in the control group, 153 in the intervention group), of whom 202 (64%) had radius fractures and 114 (36%) had ankle fractures. The treatment plan changed in twelve patients (3.8%; four in the control group and eight in the intervention group), seven of whom (2.2%; three in the control group and four in the intervention group) underwent a second operation. The frequency of changes in the treatment plan and of reoperations was comparable in the two groups (p = 0.36). On follow-up at six weeks and one year, the results with respect to functional outcomes and pain were comparable.

CONCLUSION

In this trial, routine postoperative x-rays after the osteosynthesis of distal radial fractures and ankle fractures did not improve the care of patients who had undergone standardized intraoperative imaging.

Intraoperative fluoroscopy alone versus routine post-operative X-rays in identifying return to theatre after fracture fixation

BACKGROUND

Post-operative imaging aims to assess fracture reduction and fixation with better resolution than intraoperative fluoroscopy (IF). However, this routine practice may increase costs and delay the discharge of patients. The aim of this study is to assess the role of post-operative imaging in identifying patients that require a return to theatre following the use of IF.

METHODS

A retrospective cohort study was conducted in a single health network comprising of two hospitals over 1 year. All fracture fixations that required IF were included. Patients who had post-operative imaging were identified and complications requiring a return to theatre were obtained. Non-trauma patients and those who did not have IF were excluded.

RESULTS

A total of 1319 patients had IF. Of these patients, 1131 patients had post-operative radiographs within 7 days of their operation. In total, 12 patients (1.1%) returned to theatre as a result of a finding identified in their post-operative imaging. The calculated number of X-rays required to be taken to identify a complication was 94. The main reasons identified for these cases to require a return to theatre despite having had IF included: (i) insufficient quality/views of IF, (ii) loss of position/new injury occurring in post-operative period and (iii) poor reduction/fixation demonstrated intraoperatively that was missed/accepted.

CONCLUSION

The use of post-operative radiographs can identify significant complications despite the use of IF in trauma patients. However, further consideration needs to be made regarding the benefits and costs of this practice in evaluating its clinical effectiveness.

Saving time in the fracture clinic: 2 weeks post-operative plain films following open reduction and internal fixation of distal radius fractures do not affect management

INTRODUCTION

Distal radius fractures represent up to one in every sixth treated fracture. The majority of these are intra-articular and require operative management. Many recent studies advocate for the use of volar plating fixation. Following fixation, most patients attend the fracture clinic at 2 and 6 weeks post-operatively and may get repeat imaging at both visits, resulting in longer wait times and repeat exposure to radiation. Revision surgery is however rarely performed in the 2- to 6-week period, raising the question of the necessity of plain film at 2 weeks.

AIM

Improve patient satisfaction in the fracture clinic by reducing wait time in fracture clinic and limiting exposure to radiation.

METHOD

The number of distal radius open reduction and internal fixation (ORIF) over a 12-month period was retrieved using theatre logbooks. Patient details were used to check whether a plain film radiograph had been performed 2 weeks post-operatively. Subsequently, patients' records were used to determine if revision surgery was performed or planned.

RESULTS

In total, 123 distal radius ORIF were performed between January 2018 and January 2019. Two-week check radiographs were performed for 82 patients (67%). One patient (0.8%) underwent revision surgery following review of intra-operative imaging. No patients underwent revision ORIF following 2-week plain film.

CONCLUSION

Repeat imaging at 2 weeks following distal radius ORIF did not change management of distal radius fractures in this study. Therefore, our data suggests 2-week plain films should not routinely be ordered for these patients which will reduce wait time and exposure to radiation.

Influence of radiographic examination findings on recommendations made during routine clinical re-evaluation of dogs with uncomplicated tibial plateau leveling osteotomy

OBJECTIVE

To determine the influence of follow-up radiographic examination on recommendations made during routine clinical re-evaluation of dogs that had undergone uncomplicated tibial plateau leveling osteotomy (TPLO).

STUDY DESIGN

Retrospective multi-institutional case series.

ANIMALS

Client-owned dogs (N = 1010) that underwent uncomplicated TPLO.

METHODS

Records from 11 institutions were searched for dogs that had been treated with unilateral TPLO and had no history of postoperative complications before their routine follow-up examination. The frequency of change in further clinical recommendations resulting from client- or clinician-voiced concerns or radiographic abnormalities was investigated.

RESULTS

Follow-up evaluation was performed at a median of 6 (range, 4-15) weeks after TPLO. Radiographic examination findings contributed to a change in recommendations in 4.15% (38/915) of dogs presented without client concerns and without abnormalities at orthopedic examination. Abnormal radiographic findings alone influenced the management of 3.76% (38/1010) of dogs. An association was detected between clinical features and radiological findings leading to a change in recommendations (P < .0001). Administration of analgesia at the time of follow-up was associated with radiographic abnormalities (P = .017) and change in postoperative plans (P = .0007).

CONCLUSION

Radiographic examination findings at follow-up did not influence the management of most dogs with uncomplicated TPLO.

CLINICAL SIGNIFICANCE

Radiographic examination findings are unlikely to influence the treatment of dogs that seem to be recovering uneventfully from an uncomplicated TPLO without concerns from clients, analgesia, or abnormal findings on thorough orthopedic examination by a surgical specialist, at the time of the planned clinical re-evaluation.

The Role of Early Post-Operative Radiographs Following Distal Radius Fracture Fixation with a Volar Locking Plate: Time for Change?

Background: The role of early radiographic imaging in the management of distal radius fractures (DRFs) is unclear. The aim of this study was to assess whether early post-operative radiographs for DRFs influences the ongoing management of this patient group. We hypothesize that routine early radiographs do not influence the management of DRFs. Methods: This was a retrospective review of patients undergoing open reduction and internal fixation using a volar locking plate between 2012 and 2017 at our institution. Patients were identified using hospital electronic databases. Clinical information was gathered from the electronic health records and PACS systems and analysed on a spreadsheet. An early post-operative radiograph was defined by the authors as imaging on a patient's first postoperative visit. Results: 237 patients were identified. The median number of days patients were reviewed post-operatively was 13 (interquartile range 9-16). 172 (73.1%) patients had early post-operative radiographs, with 100 (58.1%) intra-articular and 72 (41.9%) extra-articular fractures. Of patients who underwent imaging, 7 (4.0%) had their post-operative fracture management altered (7 intra-articular, 0 extra-articular) with 1 (0.58%) requiring immediate surgical revision as indicated by imaging. Conclusions: Our study questions the value of routine early post-operative radiographs in the management of distal radius fracture fixations, in particular if the fracture is extra-articular. This is of importance in the setting of constrained resources and represents a poor use of limited healthcare facilities, as well as unnecessary radiation exposure.

Reduction of routine radiographs in the follow-up of distal radius and ankle fractures: Barriers and facilitators perceived by orthopaedic trauma surgeons

RATIONALE, AIMS, AND OBJECTIVES

Studies suggest that routine radiographs during follow-up of distal radius and ankle fractures result in increased radiation exposure and health care costs, without influencing treatment strategies. Encouraging clinicians to omit these routine radiographs is challenging, and little is known about barriers and facilitators that influence this omission. Therefore, this study aims to identify barriers and facilitators among orthopaedic trauma surgeons that might prove valuable towards the design of a deimplementation strategy.

METHODS

A mixed-method approach was used. First, interviews were conducted with orthopaedic trauma surgeons and patients (n = 16). Subsequently, a questionnaire was developed. This questionnaire was presented to 228 orthopaedic trauma surgeons in the Netherlands. Regression analyses were performed in order to identify which variables were independently associated to the decision to stop performing routine radiographs 6 and 12 weeks after trauma if proven not effective in a large randomized controlled trial.

RESULTS

In total, 130 (57%) respondents completed the questionnaire. Of these, 71% indicated they would stop ordering routine radiographs if they were proven not effective. Three facilitators were independent predictors for the intention to omit routine radiographs: This will "lead to lower health care costs" (Odds Ratio [OR]: 5.38 and 4.38), the need for "incorporation in the regional protocol" (OR: 3.66 and 2.66), and this will "result in time savings for the patient" (OR: 4.84).

CONCLUSIONS

We identified three facilitators that could provide backing for a deimplementation strategy aimed at a reduction of routine radiographs for patients with distal radius and ankle fractures.

Radiologic evaluation of fracture healing

While assessment of fracture healing is a common task for both orthopedic surgeons and radiologists, it remains challenging due to a lack of consensus on imaging and clinical criteria as well as the lack of a true gold standard. Further complicating this evaluation are the wide variations between patients, specific fracture sites, and fracture patterns. Research into the mechanical properties of bone and the process of bone healing has helped to guide the evaluation of fracture union. Development of standardized scoring systems and identification of specific radiologic signs have further clarified the radiologist's role in this process. This article reviews these scoring systems and signs with regard to the biomechanical basis of fracture healing. We present the utility and limitations of current techniques used to assess fracture union as well as newer methods and potential future directions for this field.

Do Immediate Postoperative Radiographs Change Patient Management After Fracture Fixation? A Systematic Review

OBJECTIVES

To evaluate whether immediate (0-3 days) postoperative radiography leads to alterations in the management of patients postfracture fixation.

DATA SOURCES

Systematic review of English-language articles in the MEDLINE (1946-2016), EMBASE (1974-2016), CDSR (2005-2016), CENTRAL (1948-2016), and Google Scholar databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

STUDY SELECTION

Randomized or non-randomized controlled trials and prospective or retrospective cohort studies that addressed surgical management of the upper extremity, lower extremity or hip fractures were eligible for review. All included studies needed to have performed radiography within 0-3 days of surgery and reported any directly resulting management changes.

DATA EXTRACTION

Data were independently extracted by 2 reviewers using a standardized data collection form with predefined data fields for demographics, interventions, study methods, complications, and management outcomes.

DATA SYNTHESIS

A random-effects model was applied, and pooled effects for absolute benefit increase (ABI) and number needed to treat (NNT) were calculated.

CONCLUSIONS

Combining the 11/12 articles that reported by patient numbers, the ABI of immediate postoperative radiography for management change was 0.13% [95% confidence interval (CI), 0.00078%-0.60%; NNT = 753]. The ABI for identification of complications was 0.22% (95% CI, 0.0015%-1.24%; NNT = 453). Current literature suggests that immediate postoperative radiography does not lead to management change in most patients after fracture fixation. More comprehensive reporting, along with further prospective comparative research, is encouraged.

Use of Postoperative Radiographs following Operative Fixation of Distal Radius Fractures

BACKGROUND

Recent studies show that routine postoperative films after open reduction and internal fixation for distal radius fractures rarely alter clinical management. This population study evaluates the use of postoperative radiographs after distal radius fracture fixation.

METHODS

The authors studied insurance claims from the Truven MarketScan databases to identify patients aged 18 years and older who underwent open reduction and internal fixation for a distal radius fracture between 2009 and 2011. Two years of postoperative data were collected to determine the number and timing of postoperative radiographs and related clinical events, including complications and reoperation. The authors also compared outcomes between cohorts who did and did not undergo radiography on the day of surgery.

RESULTS

The authors identified 20,041 patients who met study criteria. On average, 3.8 ± 2.1 radiographs per patient were obtained during the 2-year follow-up, with 3.0 ± 1.4 being obtained within the first 3 months; 59, 81, and 91 percent of patients did not undergo further imaging after 3, 6, and 12 months postoperatively, respectively. Radiographs were obtained on the day of surgery in 47 percent of patients (n = 9372), and more were obtained overall for these patients in the postoperative period (4.4 versus 3.2). Early reoperation rates (within 14 days) following distal radius fractures between patients who did and did not undergo same-day radiography were 5 percent versus 3 percent.

CONCLUSIONS

On average, four radiographs per patient were obtained following open reduction and internal fixation for a closed distal radius fracture. Nearly 50 percent of individuals underwent radiography on the day of surgery, despite low reoperation rates in the early postoperative period. An evidence-based approach to postoperative radiography has the potential to reduce distal radius fracture-related health care use.

Routine follow-up radiographs for distal radius fractures are seldom clinically substantiated

INTRODUCTION

The 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.

METHODS

This 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.

RESULTS

1042 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.

CONCLUSION

Although 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.
