Evaluating the Utility of Follow-up Radiographs for Isolated Radial Head Fractures Undergoing Initial Nonoperative Treatment

Which radial head fractures are best treated surgically?

Despite the common occurrence of radial head fractures, there is still a lack of consensus on which radial head fractures should be treated surgically. The radial head is an important secondary stabilizer in almost all directions. An insufficient radial head can lead to increased instability in varus-valgus and posterolateral rotatory directions, especially in a ligament-deficient elbow. The decision to perform surgery is often not dictated by the fracture pattern alone but also by the presence of associated injury. Comminution of the radial head and complete loss of cortical contact of at least one fracture fragment are associated with a high occurrence of associated injuries. Nondisplaced and minimally displaced radial head fractures can be treated non-operatively with early mobilization. Displacement (>2 mm) of fragments in radial head fractures without a mechanical block to pronation/supination is not a clear indication for surgery. Mechanical block to pronation/supination and comminution of the fracture are indications for surgery. The following paper reviews the current literature and provides state-of-the-art guidance on which radial head fractures should be treated surgically.

The Utility of Routine Follow-up Radiographs in the Nonoperative Management of Proximal Humerus Fractures in Patients 65 Years and Older

Whereas prior studies have aimed to define the utility of routine radiographs for the closed treatment of upper extremity fractures, it remains uncertain whether routine radiographs influence management decisions for nonoperative treatment of proximal humerus fractures (PHFs). The purpose of this investigation was to assess the utility of routine radiographic monitoring of closed PHFs in elderly patients initially indicated for nonoperative treatment. We identified all patients 65 years and older who had a PHF from 2016 to 2019. We excluded cases of pathologic fractures or peri-prosthetic fractures, nonunion, malunion, cases with insufficient follow-up, and cases for which surgery was indicated either in the emergency department or at the first orthopedic visit. After applying these exclusion criteria, 402 cases remained. We recorded baseline demographics and fracture descriptions and noted any conversion to operative treatment after the initial office visit. Two-part fractures were most common (56%). Of the 402 fractures indicated for nonoperative treatment, 21 (5%) were converted to operative management during the follow-up period. Nine fractures (2%) were converted to operative management within 30 days of the first office visit. Eight cases (2%) were converted to operative treatment more than 120 days after the initial office visit: 6 due to nonunion and 2 due to posttraumatic arthritis. For patients 65 years and older who undergo initial nonoperative treatment of a PHF, routine follow-up radiographs do not appear to alter management decisions. Given the risk and cost associated with routine radiographs, surgeons should consider forgoing these images in the absence of clinical concern. [Orthopedics. 2023;46(4):e244-e248.].

Low-value injury care in the adult orthopaedic trauma population: A systematic review

OBJECTIVES

Fifteen potentially low value practices in adult orthopaedic trauma care were previously identified in a scoping review. The aim of this study was to synthesise the evidence on these practices.

METHODS

We searched four databases for systematic reviews, randomised controlled trials (RCTs), cohort studies and case series that assessed the effectiveness of selected practices. Methodological quality was evaluated using the Measurement Tool to Assess Systematic Reviews version 2 (AMSTAR-2) for systematic reviews and the Critical Appraisal Checklist for Case Series. We evaluated risk of bias with the Cochrane revised tool for RCTs and the risk of bias in non-randomised studies of interventions tool for observational studies. We summarised findings with measures of frequency and association for primary outcomes.

RESULTS

Of the 30,670 records screened, 70 studies were retained. We identified high-level evidence of lack of effectiveness or harm for routine initial imaging of ankle injury, orthosis for A0-A3 thoracolumbar burst fracture in patients <60 years of age, cast or splint immobilisation for suspected scaphoid fracture negative on MRI or confirmed fifth metacarpal neck fracture, and routine follow-up imaging for distal radius and ankles fractures. However, evidence was mostly based on studies of low methodological quality or high risk of bias.

CONCLUSION

In this review, we identified clinical practices in orthopaedic injury care which are not supported by current evidence and whose use may be questioned. In future research, we should measure their frequency, assess practice variations and evaluate root causes to identify practices that could be targeted for de-implementation.
