Is there an optimal timing for surgical treatment of pediatric supracondylar humerus fractures in the first 24 hours?

Value-Driven Pediatric Supracondylar Humerus Fracture Care: Implementing Evidence-Based Practices

Supracondylar humerus fractures are high-volume injuries in children; therefore, value-driven treatment has far-reaching implications for patients and families as well as healthcare systems. Children younger than 5 years can remodel posterior angulation. Most Type IIa fractures will maintain alignment after closed reduction. Many patients with surgical fractures can safely wait for nonemergent fixation. Outpatient surgery is associated with shorter surgical time, lower costs, and fewer return visits to the emergency department with no increase in adverse events. Type III fractures treated the following day do not have higher rates of open reduction, and patients with associated nerve injuries have no difference in recovery time compared with those treated more urgently. Pediatric-trained surgeons generally provide more efficient care (shorter surgical time and less after-hours surgery); however, their outcomes are equivalent to non-pediatric orthopaedic surgeons. Community hospitals have lower costs compared with teaching hospitals; therefore, transferring patients should be avoided when feasible. Postoperative care can be streamlined in uncomplicated cases to minimize radiographs, therapy referrals, and multiple visits. Splinting offers safer, lower cost immobilization over casting. With staffing shortages and an increasingly burdened healthcare system, it is imperative to maximize nonsurgical care, use outpatient facilities, and minimize postoperative requirements without negatively affecting patient outcomes.

Effectiveness of an early operating room start time in managing pediatric trauma

BACKGROUND

The timing of operative treatment for pediatric supracondylar humerus fractures (SCHF) and femoral shaft fractures (FSF) remains controversial. Many fractures previously considered to be surgical emergencies, such as SCHF and open fractures, are now commonly being treated the following day. When presented with an urgent fracture overnight needing operative treatment, the on-call surgeon must choose whether to mobilize resources for a late-night case or to add the case to an elective schedule of the following day.

AIM

To describe the effect of a program allowing an early operating room (OR) start for uncomplicated trauma prior to an elective day of surgery to decrease wait times for surgery for urgent fractures admitted overnight.

METHODS

Starting in October 2017, patients were eligible for the early slot in the OR at the discretion of the surgeon if they were admitted after 21:00 the previous night and before 05:00. We compared demographics and timing of treatment of SCHF and FSF treated one year before and after implementation as well as the survey responses from the surgical team.

RESULTS

Of the 44 SCHF meeting inclusion criteria, 16 received treatment before implementation while 28 were treated after. After implementation, the mean wait time for surgery decreased by 4.8 h or 35.4% (13.4 h vs 8.7 h; P = 0.001). There were no significant differences in the operative duration, time in the post anesthesia care unit, and wait time for discharge. Survey results demonstrated decreased popularity of the program among nurses and anesthesiologists relative to surgeons. Whereas 57% of the surgeons believed that the program was effective, only 9% of anesthesiologists and 16% of nurses agreed. The program was ultimately discontinued given the dissatisfaction.

CONCLUSION

Our findings demonstrate significantly reduced wait times for surgery for uncomplicated SCHF presenting overnight while discussing the importance of shared decision-making with the stakeholders. Although the program produced promising results, it also created new conflicts within the OR staff that led to its discontinuation at our institution. Future implementations of such programs should involve stakeholders early in the planning process to better address the needs of the OR staff.

Preoperative vascular assessment of patients with a supracondylar humeral fracture and a perfused, pulseless limb

The 'pink, pulseless hand' is often used to describe the clinical situation in which a child with a supracondylar fracture of the humerus has normal distal perfusion in the absence of a palpable peripheral pulse. The management guidelines are based on the assessment of perfusion, which is difficult to undertake and poorly evaluated objectively. The aim of this study was to review the available literature in order to explore the techniques available for the preoperative clinical assessment of perfusion in these patients and to evaluate the clinical implications. A systematic literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered prospectively with the International Prospective Register of Systematic Reviews. Databases were explored in June 2022 with the search terms (pulseless OR dysvascular OR ischaemic OR perfused OR vascular injury) AND supracondylar AND (fracture OR fractures). A total of 573 papers were identified as being suitable for further study, and 25 met the inclusion criteria for detailed analysis. These studies included a total of 504 patients with a perfused, pulseless limb associated with a supracondylar humeral fracture. Clinical examination included skin colour (23 studies (92%)), temperature (16 studies (64%)), and capillary refill time (13 studies (52%)). Other investigations included peripheral oxygen saturation (SaO2) (six studies (24%)), ultrasound (US) (14 (56%)), and CT angiogram (two studies (8.0%)). The parameters of 'normal perfusion' were often not objectively defined. The time to surgery ranged from 1.5 to 12 hours. A total of 412 patients (82%) were definitively treated with closed or open reduction and fixation, and 92 (18%) required vascular intervention, ranging from simple release of entrapped vessels to vascular grafts. The description of the vascular assessment of the patient with a supracondylar humeral fracture and a pulseless limb in the literature is variable, with few objective criteria being used to define perfusion. The evidence base for decision-making is limited, and further research is required. We were able, however, to make some recommendations about objective criteria for the assessment of these patients, and we suggest that these are performed frequently to allow the detection of any deterioration of perfusion.

Early versus delayed treatment of lateral condylar fracture of the humerus with > 2 mm displacement in children: a retrospective study

BACKGROUND

The purpose of this study was to investigate the clinical and functional outcomes of early versus delayed treatment of pediatric lateral condylar fractures of the humerus with a displacement greater than 2 mm.

METHODS

Sixty-seven children treated surgically at our hospital from March 2016 to September 2021 for lateral condylar fracture of the humerus with displacement > 2 mm were retrospectively analyzed. The children were divided into two groups where early surgery consisted of patients being operated on within 24-h post-injury (n = 36) and delayed surgery consisted of children operated after 24-h post-injury (n = 31). Clinical and functional results were compared between the two groups.

RESULTS

There were no significant differences between the two groups in terms of operation time, blood loss and incidences of perioperative complications. However, mean length of incision was significantly greater (P < 0.0001) in the delayed treatment group (5.68 ± 1.08 cm) compared to the early treatment group (3.89 ± 0.82 cm). No differences were found in functional outcomes, consisting of the Baumann angle of the affected limb, the carrying angle, Mayo Elbow Performance Score, and Flynn's criteria at final follow-up.

CONCLUSIONS

Delay in surgery for more than 24 h after injury does not influence the clinical and functional results for lateral condylar fracture of the humerus with displacement > 2 mm in children. However, delayed open reduction and pinning may increase the incision length possibly due to increased edema.

Predictive factors for open reduction of flexion-type supracondylar fracture of humerus in children

Objective

The incidence of open reduction and internal fixation (ORIF) in flexion-type supracondylar humerus fractures (SCHF) in children is significantly higher than that of extension-type fractures. This study aimed to identify risk factors for ORIF in flexion-type SCHF.

Methods

One hundred seventy-one patients with Wilkins type III flexion-type SCHF from January 2012 to December 2021 were retrospectively enrolled in a tertiary paediatric hospital. Patients were divided into ORIF group versus closed reduction and internal fixation (CRIF) group. Then, patients data of age, sex, injury side, obesity, deviation of displacement, fracture level, rotation, nerve injury, and delay from injury to surgery were reviewed. Univariate analysis and multivariate logistic regression were used to identify independent risk factors and odds ratios (OR) of ORIF.

Results

Overall, 171 children with type III flexion-type SCHF were analyzed (average aged 7.9 ± 2.8 years). Displacement was lateral in 151 cases, medial in 20. 20 cases had combined ulnar nerve injury. The failed closed reduction rate was 20%. Univariate analysis indicated age, distal fracture fragment rotation, and ulnar nerve injury were significantly associated with ORIF. (P = 0.047, P = 0.009, and P = 0.001, respectively). Multivariate logistic regression analysis showed that distal fracture fragment rotation (OR, 3.3; 95%CI:1.1–9.5; P = 0.028) and ulnar nerve injury (OR, 6.4; 95%CI:2.3–18.3; P = 0.001) were independent risk factors; however, the age was not an independent one (OR, 1.5; 95%CI:0.6–3.5; P = 0.397) for ORIF in the Wilkins type III flexion-type SCHF.

Conclusion

Distal fracture fragment malrotation on initial x-rays and ulnar nerve injury were significant risk factors for ORIF in Wilkins type III flexion-type SCHF. Surgeons should prepare tourniquets or other open reduction instruments when treating these types of fractures.

Early Versus Delayed Treatment for Gartland Type III Supracondylar Humeral Fractures in Children: A Systematic Review and Meta-analysis

PURPOSE

The timing of treatment for Gartland type III supracondylar fractures has been an area of contention as it was previously thought to be a surgical emergency. The aim of this systematic review and meta-analysis is to clarify whether there is a difference in perioperative outcomes between early and delayed treatment for Gartland type III supracondylar humeral fractures in children.

METHODS

Literature search and study selection were performed according to the PRISMA process. The early surgery (ES) and delayed surgery (DS) groups were defined by the authors of each study included, based on the time to surgery. The primary outcome was the risk of conversion to open reduction. The secondary outcome was perioperative complication risks.

RESULTS

A total of 14 studies met the eligibility criteria (n = 1263 patients), of which 665 (52.7%) patients had undergone early surgery, while 598 (47.3%) had delayed surgery. On meta-analysis, there was no significant difference between ES and DS for the outcome of open reduction conversion risk. There was also no significant difference for the secondary outcomes of post-operative compartment syndrome, iatrogenic nerve injury, vascular injury, and surgical site infection.

CONCLUSION

Despite the limitations in the literature, evidence exists to support the notion that a delayed approach to the surgical treatment of Gartland type III supracondylar humeral fractures in children does not result in an increased risk of converting to open reduction and perioperative complications.

Pediatric Supracondylar Humerus Fractures: Should We Avoid Surgery during After-Hours?

Pediatric supracondylar humerus fractures occur frequently. Often, the decision has to be made whether to operate immediately, e.g., during after-hours, or to postpone until office hours. However, the effect of timing of surgery on radiological and clinical outcomes is unclear. This literature review with the PICO methodology found six relevant articles that compared the results of office-hours and after-hours surgery for pediatric supracondylar humerus fractures. The surgical outcomes of both groups in these studies were assessed. One of the articles found a significantly higher “poor fixation rate” in the after-hours group, compared with office hours. Another article found more malunions in the “night” subgroup vs. the “all groups but night” group. A third article found a higher risk of postoperative paresthesia in the “late night” subgroup vs. the “day” group. Lastly, one article reported increased consultant attendance and decreased operative time when postponing to office hours more often. No differences were reported for functional outcomes in any of the articles. Consequently, no strong risks or benefits from surgical treatment during office hours vs. after-hours were found. It appears safe to postpone surgery to office hours if circumstances are not optimal for acute surgery, and if there is no medical contraindication. However, research with a higher level-of-evidence is needed make more definite recommendations.
