Complications With Surgical Treatment of Pediatric Supracondylar Humerus Fractures: Does Surgeon Training Matter?

Pediatric orthopedic surgeons may perform better in terms of surgical outcomes in type 3 supracondylar humerus fractures: a comparative analysis

Supracondylar fractures of the humerus represent the most common surgical fractures in pediatric patients. There is a discourse regarding the influence of the surgeon training on treatment. Different studies show equivocal effect of subspecialty training. We conducted a single center case control study to evaluate the outcomes of type 3 fractures (fully displaced) comparing pediatric-trained orthopedic surgeons (PTOS) and non-pediatric trained orthopedic surgeons (NTOS). In this retrospective study, we investigated the surgical outcomes of type 3 supracondylar fractures of the humerus in children treated between the years 2012 and 2019, divided by surgeon type. During the research, a policy reform at our department was established and PTOS became the only surgeons for those injuries starting from September 2017. Patients' demographics, perioperative details, and postoperative course were recorded. Primary outcome was reoperations, and secondary outcomes were open reductions, infections, length of surgery, and neurological deficits. 1175 patients were diagnosed with supracondylar fractures at our Level I trauma center, and 346 cases were diagnosed with radiologically confirmed type 3. Overall, 312 cases were analyzed; 113 cases were diagnosed before 1 September 2017 and treated by NTOS, and 199 cases were treated by PTOS until 31 December 2019; 7.1% (8) of the patients treated by NTOS had to be reoperated compared to 1.5% (3) of the patients treated by PTOS ( P  = 0.014). There was significant difference looking at postsurgical complications and surgery length. This study's findings suggest that PTOS achieve superior outcomes when treating patients with type 3 supracondylar humerus fractures. Level of evidence: Level III.

Pediatric Supracondylar Humerus Fractures: Treatment by a Pediatric Orthopedic Surgeon Versus a Non-pediatric Orthopedic Surgeon

INTRODUCTION

Supracondylar humerus fractures are the most common surgically treated fracture in children. National trends have demonstrated an increase in transfers of supracondylar fractures to pediatric hospitals due to the perception that supracondylar fractures need to be treated by pediatric specialists. The objectives of the study are to compare the outcomes of surgically treated pediatric supracondylar humerus fractures (PSCHF) between a pediatric orthopedic surgeon and a non-pediatric orthopedic surgeon at a single academic medical center; to assess radiographic reduction, the number of pins used, surgical time, Flynn criteria outcomes, and complications associated with PSCHF treatment by both types of surgeons; to determine if there is a significant difference in outcomes between pediatric and non-pediatric orthopedic surgeons in the treatment of PSCHF.

METHODS

Forty-seven consecutive pediatric patients, with an average age of 5.5 years old, who had undergone surgical correction for supracondylar humerus fractures during 2019 were included in this study. The intervention performed was closed reduction and percutaneous pinning. The main outcome measured: radiographic reduction on the AP and lateral X-ray view, number of K wires used, use of a medial K wire, time of surgery, the Flynn criteria, and complications. The Human Research Protection Program (HRPP) at Penn State approval was obtained.

RESULTS

Radiographic reductions as measured by Bauman's angle and the position of the anterior humeral line were excellent and similar between surgeons. The pediatric orthopedic surgeon used more medial K wires (p=0.0007), fewer K wires (p=0.0065), and the length of surgery was shorter (p=0.019). The Flynn criteria were similar with equal excellent and good results. For both surgeons, no complications such as loss of reduction, infection, iatrogenic nerve injury, compartment syndrome, or cubitus varus occurred.

CONCLUSIONS

Outcomes of treatment of displaced PSCHF by the pediatric and non-pediatric orthopedic surgeons were equal. The results of this study reaffirm the assertion that both pediatric and non-pediatric orthopedic surgeons have sufficient training and skill to treat these common fractures, thereby contributing to a more informed decision-making process in clinical practice.

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.

Which pediatric supracondylar humerus fractures are high risk for conversion to open reduction?

Supracondylar humerus fractures are common pediatric injuries encountered by orthopedic surgeons. Displaced fractures are treated operatively with closed reduction and percutaneous pinning or open reduction of injuries that cannot be adequately closed reduced. The purpose of this study is to identify preoperative injury characteristics associated with open reduction. Retrospective chart review was performed on all AO type 13A (Gartland type) supracondylar humerus fractures in patients 2-13 years old treated surgically at a single level 1 trauma center over 6 years. Preoperative demographics and radiographic parameters were obtained for all patients. Primary outcomes were closed reduction or conversion to open reduction of fractures prior to k-wire fixation. Initial bivariate analysis was done using Chi-square tests. Final multivariate analysis with Bonferonni correction was performed using a backward, stepwise regression model including potential predictor variables identified in the bivariate analysis. A total of 211 patients received surgical treatment and 18 of those patients (8.5%) failed closed reduction and underwent open reduction. Final multivariate analysis demonstrated that only flexion type [relative risk (RR), 10.2] and coronal displacement more than 7 mm (RR, 4.49) were significant preoperative factors for conversion to open reduction. Patients with significant coronal displacement and flexion-type injuries are markers of challenging reduction and are at high risk for conversion to open reduction.

Impact of Pediatric Orthopaedic Fellowship Training on Pediatric Supracondylar Humerus Fracture Treatment and Outcomes: A Meta-analysis

BACKGROUND

Supracondylar humerus (SCH) fractures are common pediatric injuries, typically requiring closed reduction and percutaneous pinning or open reduction. These injuries are managed frequently by both pediatric-trained (PTOS) and nonpediatric-trained (NTOS) orthopaedic surgeons. However, some literature suggests that complications for pediatric injuries are lower when managed by PTOS. Therefore, this meta-analysis sought to compile existing literature comparing patients treated by PTOS and NTOS to better understand differences in management and clinical outcomes.

METHODS

Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) methodology, a systematic review was conducted for all articles comparing SCH fractures managed by PTOS and NTOS in 4 online databases (PubMed, Embase, CINAHL, Cochrane). Study quality was assessed through the use of the Newcastle-Ottawa Scale. Meta-analyses were then performed for postoperative outcomes using pooled data from the included studies. Statistics were reported as odds ratios and 95% CI.

RESULTS

This search strategy yielded 242 unique titles, of which 12 underwent full-text review and 7 met final inclusion. All studies were retrospective and evaluated patients treated in the United States. There were a total of 692 and 769 patients treated by PTOS and NTOS, respectively. PTOS had shorter operative times [mean difference, 13.6 min (CI, -23.9 to -3.4), P=0.01] and less frequently utilized a medial-entry pin [odds ratios, 0.36 (CI, 0.2 to 0.9), P=0.03]. There were no differences in time to treatment, the necessity of open reduction, postoperative Baumann angle, or complications including surgical site infection or iatrogenic nerve injury.

CONCLUSIONS

Despite shorter operative times and lower frequency of cross-pinning when treated by PTOS, pediatric SCH fracture outcomes are similar when treated by PTOS and NTOS. These findings demonstrate that these fractures may possibly be treated safely by both PTOS and experienced fellowship-trained academic NTOS who are comfortable managing these injuries in pediatric patients.
