Radiation Reduction Strategies in Pediatric Orthopaedics

Safety and reliability of ultrasound-assisted reduction in the conservative management of completely displaced paediatric distal radius fractures

PURPOSE

To assess the efficacy of ultrasound-assisted reduction in the conservative management of completely displaced pediatric distal radius fractures.

METHODS

The efficacy of ultrasound-assisted reduction versus conventional reduction was compared in a single-centre, retrospective, cross-sectional study involving 51 consecutive paediatric patients with completely displaced distal radius fractures, following manual reduction, from May 2021 to May 2023. The study group received ultrasound-assisted reduction (n = 24), while the control group underwent conventional blind manual reduction (n = 27). Comparative analysis included general clinical data, initial reduction success rates, frequency of exposure to radiation during reduction, post-reduction alignment rates, post-reduction angulation, re-displacement rates, conservative treatment failure rates, pain scores, and wrist joint scores at the last follow-up.

RESULTS

All enrolled cases underwent manual reduction and conservative management. In the study group, all 24 patients underwent successful initial reduction procedures, with only one exposure to radiation during the entire process. Notably, no patient experienced re-displacement while in plaster, and the conservative treatment proved effective. The reduction and positioning rates were impressive, with success rates of 86.63 ± 3.65% in the coronal plane and 94.79 ± 3.06% in the sagittal plane. Furthermore, the post-reduction angulation was only 3.58 ± 0.65 degrees in the coronal plane and 8.70 ± 1.45 degrees in the sagittal plane. By contrast, within the control group comprising 27 patients, only 15 achieved successful initial reductions. Unfortunately, 12 patients required multiple exposure to radiation throughout the procedure. Furthermore, nine patients underwent re-displacement while in plaster and seven did not achieve successful conservative treatment. The alignment rates of the control group were similar to those of the study group (84.67 ± 4.35% in the coronal plane and 82.56 ± 5.45% in the sagittal plane). Similarly, the post-reduction angulation remained consistent, measuring 3.93 ± 0.87 degrees in the coronal plane and 12.03 ± 1.32 degrees in the sagittal plane. There were no statistically significant differences in pain scores during the process of fracture reduction and in wrist joint function scores at the final follow-up (P > 0.05).

CONCLUSION

Ultrasound-assisted reduction in the conservative management of completely displaced paediatric distal radius fractures can enhance the initial reduction success rate, decrease the risk of subsequent redisplacement, minimize patient exposure to radiation, and yield favorable clinical outcomes. It is a safe and reliable approach.

Pediatric Orthopaedic Surgeons Manage Pediatric Diaphyseal Clavicle Fractures Differently Than Nonpediatric Orthopaedic Specialists

BACKGROUND

Pediatric clavicle fractures are often managed by physicians with and without pediatric subspecialty training. The aim of this study is to identify if variability of practice exists between pediatric orthopaedic surgeons versus nonpediatric orthopaedic specialists during management of pediatric diaphyseal clavicle fractures.

METHODS

Patients ≤18 years of age with an acute, closed diaphyseal clavicle fracture treated between January 2018 and July 2023 by a large hospital-employed multispecialty orthopaedic practice (in a regional and academic health network) were retrospectively reviewed. The study involved 26 orthopaedic surgeons (including 3 pediatric, 8 sports medicine, and 6 general) and 11 nonoperative sports medicine physicians, all of which accept patients ranging 0 to 18 years of age. Exclusion criteria included open or impending open fractures and insufficient data. Demographic, radiographic, and outpatient treatment parameters were recorded. Age groups were separated into <10 and ≥10 years old to control for age-associated differences.

RESULTS

Among 560 pediatric clavicle fractures, 385 met inclusion criteria (43.6% of which were treated by a pediatric orthopaedic surgeon), and 361 were treated nonoperatively. Follow-up averaged 48.8 days until orthopaedic discharge and 16.9 months until the most recent well-child visit (80% had a well-child visit after orthopaedic discharge). No patient <10 years of age had elective surgery, but pediatric orthopaedic surgeons demonstrated lower surgical rates in adolescent patients than nonpediatric specialties (4.3% vs. 14.4%, OR=3.8, P=0.027). Among the 169 nonoperative patients <10 years of age, pediatric orthopaedic surgeons completed fewer outpatient visits (2.1±0.8 vs. 2.4±0.8, P<0.037), shorter follow-up durations (28.5±18.9 vs. 41.8±22.6 d, P<0.001), less radiographic series (2.1±0.8 vs. 2.4±1.0, P<0.047), and less total radiographs (4.3±1.8 vs. 5.0±2.3, P<0.013) than nonpediatric specialists.

CONCLUSIONS

The surgical rate of acute, closed diaphyseal clavicle fractures is lower among pediatric versus nonpediatric orthopaedic surgeons in adolescents. During nonoperative management of pediatric clavicle fractures, pediatric orthopaedic surgeons treat young patients (but not adolescents) with less outpatient visits and radiographs than nonpediatric orthopaedic physicians.

MRI as the optimal imaging modality for assessment and management of osteochondral fractures and loose bodies following traumatic patellar dislocation: a systematic review

PURPOSE

To assess the imaging modalities used for diagnosis, as well as the management decisions of patients with osteochondral fractures (OCF) and loose bodies following traumatic patellar dislocation.

METHODS

According to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA), MEDLINE, EMBASE, Web of Science, and PubMed were searched for results from January 1, 2000, to May 18, 2021, in two subsequent searches for English language studies that presented data on traumatic patellar dislocation. Quality of selected papers was assessed using the Methodological Index for Non-Randomised Studies (MINORS) and the Risk of Bias (RoB) 2.0 protocol. Results were qualitatively synthesised, and descriptive statistics were calculated.

RESULTS

Forty studies totalling 3074 patients (1407 females) were included for the analysis. The mean age was 18.9 years (range 0-69). The population included 2446 first-time dislocations. The imaging modalities used were: 71.1% MRI, 52.6% plain radiography, 12.1% CT, and 0.68% ultrasound. In the 25 studies that reported the number of OCF, a total of 38.3% of patients were found to have OCF. 43.3% of patients with a first-time dislocation, and 34.7% of patients with previous dislocations, had at least one OCF. In the included paediatric studies (maximum age ≤ 18), the presence of OCF was detected by plain radiography in 10.1% of patients, MRI in 76.6% of patients, and CT in 89.5% of patients. For management of an OCF, the surgical options include fixation for larger pieces, excision for smaller pieces, and conservative management on a case-by-case basis.

CONCLUSIONS

Based on the current available evidence, assessment and management of patellar dislocations and subsequent OCFs vary, with radiography and MRI as the main imaging modalities on presentation and particular benefit for MRI in the paediatric population. Findings from this study suggest the highest rate of OCF detection with MRI, and thus, surgeons should consider routinely ordering an MRI in patients with first-time patellar dislocation. Regarding management of OCFs, the main indication for fixation was large fragments, while smaller and poor-quality fragments are excised. Few studies choose conservative management of OCFs due to later requirements for surgical management. Future work should focus on large, high-quality studies, and implementation of randomised control trials to form guidelines for imaging patellar dislocations and management of OCFs.
