Below-elbow cast sufficient for treatment of minimally displaced metaphyseal both-bone fractures of the distal forearm in children: long-term results of a randomized controlled multicenter trial

Pediatric and Adolescent Distal Radius Fractures: Current Concepts and Treatment Recommendations

Distal radius fractures are the most common skeletal injuries requiring intervention in children. These injuries are classified by fracture pattern, location, displacement, and angulation. While each unique fracture pattern warrants slightly modified treatment plans and follow-up, the goals of treatment remain constant. Successful outcomes depend on restoration of motion and function, and attaining acceptable sagittal and coronal alignment is a necessary first step. For displaced fractures, closed reduction is often necessary to restore alignment; well-molded cast application is important to maintain fracture alignment. Fractures with bayonet apposition, if well aligned, may not need formal reduction in some patients. Special attention should be paid to the physis-not only for physeal-involving fractures but also for all distal radius fractures-given that the proximity to the physis and amount of remaining skeletal growth help guide treatment decisions. Casting technique is essential in optimizing the best chance in maintaining fracture reduction. Surgical intervention may be indicated for a subset of fractures when acceptable alignment is not achieved or is lost at subsequent follow-up. Even among experts in the field, there is little consensus as to the optimal treatment of displaced metaphyseal fractures, illustrating the need for prospective, randomized studies to establish best practices.

Intrainstitutional Changes of the Treatment of Supracondylar Humerus Fracture in Children over a Period of 9 Years

To assess changes in treatment modalities for supracondylar humerus fractures (SCHFs) at a large pediatric university hospital, we analyzed patient data from 2014 to 2022. A total of 233 SCHFs treated surgically at our hospital were included. To evaluate postoperative outcome and quality of life, DASH and EuroQol-5D-Y questionnaires were sent to patients. In addition to a significant fluctuation in fracture severity, we found an increase in training interventions (more surgeries were performed by trainees) and a significant decrease in surgery times after 2016. From 2020, there was a significant shift in the type of surgical method away from closed reduction with elastic stable intramedullary nailing (ESIN) and towards closed reduction and crossed K-wire osteosynthesis (CRK). Surgeries performed in the morning and evening hours increased, while those performed in the afternoon and after midnight decreased. After a mean follow-up of 4 years, there was no difference in elbow function between ESIN and open reduction and K-wires (ORK). Treatment with ESIN was equivalent to ORK in terms of function, at least in the medium-term follow-up. In summary, the combination of shifting treatment from SCHF to daytime hours, increasing trainee participation and using cross K-wire fixation instead of ESIN had no negative impact on surgery times. In our setting, these measures have reduced resource utilization and increased efficiency without compromising patient care.

Below- versus above-elbow cast treatment of displaced distal forearm fractures in children: A systematic review and meta-analysis of randomized controlled trials

Objectives

Distal forearm fractures are the most common pediatric fractures. This study aimed to investigate the effectiveness of below-elbow cast treatment for displaced distal forearm fractures in children compared to above-elbow cast through meta-analysis of randomized controlled trials.

Methods

Several databases from January 1, 2000 until October 1, 2021 were searched for randomized controlled trials that assessed below versus above-elbow cast treatment of displaced distal forearm fractures in pediatric patients. The main meta-analysis comparison was based on the relative risk of loss of fracture reduction between children undergoing below versus above-elbow cast treatment. Other outcome measures including re-manipulation and cast-related complications were also investigated.

Results

Nine studies were eligible of the 156 articles identified, with a total of 1049 children. Analysis was undertaken for all included studies with a sensitivity analysis conducted for studies with high quality. In the sensitivity analysis, the relative risks of loss of fracture reduction (relative risk = 0.6, 95% confidence interval = 0.38, 0.96) and re-manipulation (relative risk = 0.3, 95% confidence interval = 0.19, 0.48) between the below and above-elbow cast groups were in favor of below-elbow cast and statistically significant. Cast-related complications were in favor of below-elbow cast but did not attain statistical significance (relative risk = 0.45, 95% confidence interval = 0.05, 3.99). Loss of fracture reduction was noted in 28.9% of patients treated with above-elbow cast and 21.5% in below-elbow cast. Re-manipulation was attempted in 48.1% versus 53.8% of children who lost fracture reduction in the below-elbow cast and above-elbow cast groups, respectively.

Conclusion

Below-elbow cast treatment was favored, with statistical significance, in terms of loss of fracture reduction and re-manipulation, and was not associated with a higher risk of cast-related complications. The accumulative evidence currently does not support above-elbow cast treatment and below-elbow cast treatment should be the mainstay for displaced distal forearm fractures in children.

Health-Related Quality of Life after Fractures of the Distal Forearm in Children and Adolescents—Results from a Center in Switzerland in 432 Patients

(1) Background: We aimed to evaluate the health-related quality of life (HRQoL) in children with fractures of the distal forearm and to assess if HRQoL was associated with fracture classification; (2) Methods: We followed up on 432 patients (185 girls, 247 boys) who sustained a fracture of the distal radius or forearm from 1/2007 to 6/2007, 1/2014 to 6/2014, and 11/2016 to 10/2017. Patients filled in the Quick-DASH (primary outcome) and the Peds-QL; (3) Results: The radius was fractured in 429 and the ulna in 175 cases. The most frequent injury of the radius was a buckle fracture (51%, mean age 8.5 years), followed by a complete metaphyseal fracture (22%, 9.5 years), Salter-Harris-2 fracture (14%, 11.4 years), greenstick fracture (10%, 9.3 years), Salter-Harris-1 fracture (1%, 12.6 years), and other rare injuries. The most common treatment was closed reduction and an above-elbow cast in 138 cases (32%), followed by a cast without reduction (30%), splint (28%), and K-wire fixation and cast (9%). Definite treatment was performed initially in 95.8%, a new cast or cast wedging was performed in 1.6%, and revision surgery was performed in 2.5%. There were no open reductions and no plate fixations. After a mean follow-up of 4.2 years, patients with buckle fractures had a mean Quick-DASH of 3.3 (scale of 0–100) (complete fracture: 1.5; greenstick: 1.5; SH-1: 0.9; SH-2: 4.1; others: 0.9). The mean function score of the PedsQL ranged from 93.0 for SH-2 fractures to 97.9 for complete fractures; (4) Conclusions: In this cohort of 432 children with fractures of the distal forearm, there was equally good mean mid- and long-term HRQoL when assessed by the Quick-DASH and the PedsQL. There was a trend for children with complete metaphyseal fractures reporting better HRQoL than patients with buckle fractures or patients with Salter-Harris II fractures, however, these differences were not statistically significant nor clinically relevant.
