Key Takeaway
Note that while after-hours surgery reduces time to surgery, it is associated with more frequent alignment complications.

This meta-analysis evaluated the impact of surgical timing on outcomes for pediatric patients with supracondylar humeral fractures (SCHFs). The analysis included 913 patients and compared after-hours surgical fixation to daytime surgical fixation. The primary finding was a statistically significant reduction in time to surgery for the after-hours group (P < 0.001).

Other outcomes, including operative time (P = 0.11), medial pin fixation (P = 0.70), and open reduction (P = 0.80), showed no significant differences between the two groups. However, alignment-related complications were more frequent in the after-hours group (P = 0.04). Rates of pin migration, infection, and iatrogenic postoperative nerve injury were reported as comparable between the daytime and after-hours cohorts.

While after-hours surgery provides faster access to surgical intervention, the increased frequency of alignment-related complications suggests that surgical timing alone may not be the primary determinant of clinical outcomes. The results indicate that while logistical benefits exist for after-hours care, clinical precision remains a factor in surgical outcomes for SCHFs.

A review of data from 913 pediatric patients with supracondylar humeral fractures looked at the differences between surgeries performed during the day versus after-hours. The study compared several factors, including the time it took to perform the surgery, the time until the surgery began, and the risk of complications like infection or nerve injury.

The results showed that children who had surgery after hours were operated on sooner than those in the daytime group. However, there was no significant difference in the actual time spent in surgery or the rates of infection and nerve injury between the two groups. One notable finding was that alignment-related complications were more frequent in the after-hours group.

Because this was a meta-analysis of existing data, the results show a link between timing and outcomes rather than a direct cause. It is important to note that surgical timing alone may not be the main factor determining the final outcome for a child's recovery. Patients and families should discuss these findings with their surgical team to understand how timing affects their specific case.

What this means for you:
After-hours surgery for certain arm fractures may be faster but is linked to more alignment complications.

Common questions

Is surgery performed after hours safer for children with arm fractures?

The study found that while surgery performed after hours was started sooner, it was linked to more frequent alignment-related complications. However, there were no significant differences found between daytime and after-hours surgery regarding infection rates or nerve injuries.

How does the timing of surgery affect the procedure's duration?

The analysis of 913 patients showed no significant difference in the actual operative time between daytime and after-hours surgeries. While the timing of the start of the surgery differed, the time spent in the operating room was comparable for both groups.

Are there more complications with after-hours surgery?

The study found that alignment-related complications were more frequent in the after-hours group. Other complications, such as pin migration, infection, and nerve injury, were comparable between the daytime and after-hours groups.

BACKGROUND: Pediatric supracondylar humeral fractures (SCHFs) are among the most common elbow injuries in children and frequently require operative fixation. Although after-hours surgery is often unavoidable due to emergency presentation patterns, many centers now reserve nighttime intervention for urgent indications such as vascular compromise. Concerns nevertheless persist regarding the potential impact of after-hours surgery on surgical efficiency, technical decision-making, and postoperative outcomes. METHODS: A systematic search of PubMed, Scopus, the Cochrane Library, and Google Scholar was conducted from database inception through December 15, 2025. Comparative studies evaluating operative treatment of pediatric SCHFs performed during daytime working hours versus after-hours were included. Outcomes assessed comprised perioperative characteristics (operative time, time to surgery), intraoperative decision-making (medial pin fixation, open reduction), and postoperative complications (pin migration, alignment-related complications, infection, and iatrogenic postoperative nerve injury). RESULTS: Seven studies encompassing 913 pediatric patients met the inclusion criteria. Operative time did not differ significantly between daytime and after-hours surgery ( P =0.11). Time to surgery was shorter in the after-hours group ( P <0.001). No significant differences were observed in rates of medial pin fixation ( P =0.70) or open reduction ( P =0.80). Postoperative complications, including pin migration, infection, and iatrogenic postoperative nerve injury, were comparable between groups, whereas alignment-related complications were more frequent in the after-hours group ( P =0.04). CONCLUSIONS: Operative fixation of pediatric SCHFs showed broadly comparable perioperative efficiency, technical outcomes, and complication rates when performed during daytime or after-hours, although alignment-related complications were more frequent in the after-hours group. These findings suggest that surgical timing alone may not be the primary determinant of outcome.
