Supracondylar Fractures of the Humerus in Children

Reliability of radiographic union score and correlation of clinical outcomes in children operated for supracondylar humerus fracture: A prospective study

Background

Supracondylar humerus fractures are common in childhood, and postoperative follow-up planning for surgically treated fractures is still controversial. This study aims to investigate the interobserver and intraobserver reliability of the Radiographic Union Score for Tibial Fracture in the postoperative radiological follow-up of pediatric supracondylar humerus fractures and to evaluate the clinical results with the scores obtained during follow-up.

Methods

In this prospective study, patients who were operated on for supracondylar humerus fractures were called for follow-up three times: postoperative splint removal, pin removal, and final control. A total of 58 patients, 34 boys and 24 girls, who provided regular follow-ups, were included in the study. During follow-ups, the Radiographic Union Score for Tibial Fracture was calculated by evaluating the patients' elbow anteroposterior and lateral radiographs, and the elbow joint range of motion was recorded with a goniometer. In two experiments, orthopedic surgeons evaluated intraobserver and interobserver reliability using the intraclass correlation coefficient at different times. The patients were evaluated at the last follow-up according to the Flynn criteria.

Results

The first follow-up Radiographic Union Score for Tibial Fracture (median (range) was 8 (7-10), the second follow-up was 11 (9-12), and the third follow-up was 12 (11-12). Range of motion was 40° at the first follow-up, 90° at the second follow-up, and 120° at the third follow-up. Radiographic Union Score for Tibial Fracture and range of motion increased significantly as the weeks progressed (p < 0.001). Interobserver intraclass correlation coefficient at first follow-up was 0.80 (95% confidence interval 0.69-0.87), second follow-up was 0.85 (0.77-0.91), and third follow-up was 0.79 (0.67-0.87). Intraobserver intraclass correlation coefficient was 0.92 (0.88-0.95) at the first follow-up, 0.93 (0.98-0.96) at the second follow-up, and 1.00 (1.00-1.00) at the third follow-up. Flynn score results are functional; the cosmetic results were excellent in 46 patients, good in 4 patients, fair in 5 patients, poor in 3 patients, and cosmetic results were excellent in 54 patients and good in 4 patients.

Conclusion

Our study determined that the radiographic union of fractures in pediatric supracondylar humerus fractures is reliably evaluated with the Radiographic Union Score for Tibial Fracture score. Radiographic Union Score for Tibial Fracture can be used to provide data-driven estimates of splint and pin removal.

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.

Does Sagittal Alignment Matter? A Biomechanical Look at Pinning Pediatric Supracondylar Humerus Fractures

OBJECTIVE

Closed manipulation and percutaneous pinning is standard of care for displaced supracondylar humerus fractures, yet the optimal pin configuration, particularly in the sagittal plane, is not well defined. This study evaluates how sagittal plane pin variations affect construct strength biomechanically.

METHODS

One hundred synthetic pediatric humerus models were used to emulate supracondylar humerus fracture. The models were pinned using 4 different configurations uniformly divergent in the coronal plane with variations in the sagittal plane: (1) 2 diverging pins with the lateral pin anterior (n = 25), (2) 2 diverging pins with the lateral pin posterior (n = 25), (3) 2 parallel pins (n = 25), and (4) 3 parallel pins (n = 25). The models were tested under bending (flexion, extension, and varus) and rotational (internal and external) forces, measuring stiffness and torque. Statistical analyses identified significant differences across configurations.

RESULTS

The 2-pin parallel configuration (9.68 N/mm in extension, 8.76 N/mm in flexion, 0.14 N-m/deg in internal rotation, and 0.14 N-m/deg in external rotation) performed similarly to the 3-pin parallel setup (10.77 N/mm in extension, 7.78 N/mm in flexion, 0.16 N-m/deg in internal rotation, and 0.14 N-m/deg in external rotation), with no significant differences in stiffness. In contrast, both parallel configurations significantly outperformed the 2-pin anterior (5.22 N/mm in extension, 5.7 N/mm in flexion, 0.11 N-m/deg in internal rotation and 0.10 N-m/deg in external rotation) and posterior (9.86 N/mm in extension, 8.31 N/mm in flexion, 0.12N-m/deg in internal rotation, and 0.11 N-m/deg in external rotation) configurations in resisting deformation. No notable disparities were observed in varus loading among any configurations.

CONCLUSIONS

This study illuminates the sagittal plane's role in construct stability. It suggests that, when utilizing 2-pins, parallel configurations in the sagittal plane improve biomechanical stability. In addition, it suggests avoiding the lateral anterior pin configuration due to its biomechanical inferiority. Further research should assess ultimate strength and compare various 3-pin configurations to better delineate differences between 2-pin and 3-pin configurations regarding sagittal plane alignment.

Comparative risk of ulnar nerve injury in pediatric supracondylar humeral fractures: a multicenter evaluation of Kirschner wire fixation techniques

PURPOSE

This multicenter, retrospective cohort study aimed to compare the risk of ulnar nerve injury in pediatric supracondylar humeral fractures treated with percutaneous lateral-pins, blinded-crossed-pins, and crossed-pins with a mini-incision.

METHODS

Data were collected from 1705 children treated between January 2010 and December 2023 at four orthopedic centers in Colombia. The incidence of postoperative ulnar nerve injury was compared among three fixation techniques: lateral-pin, blinded-crossed-pin, and crossed-pin with a mini-incision.

RESULTS

A statistically significant difference in nerve injury rates was observed between the lateral-pin and both blinded-crossed-pin and mini-incision crossed-pin techniques (p < 0.001), with the lateral-pin technique demonstrating a significantly lower risk of injury. No significant difference was found between the blinded-crossed-pin and mini-incision crossed-pin techniques (p = 0.67).

CONCLUSION

Crossed-pin fixation was associated with a higher incidence of ulnar nerve injury, regardless of the use of a mini-incision. The lateral-pin technique remains the safest option for minimizing iatrogenic nerve injury. There is insufficient evidence to support the mini-incision as a safer alternative to traditional crossed-pin fixation.

Management of Pediatric Elbow Fractures and Dislocations

Pediatric elbow fractures and dislocations have always been a challenge from a diagnostic and therapeutic point of view, primarily due to the complex nature of the pediatric elbow, especially its developmental anatomy. They must be diagnosed and treated on time to prevent numerous complications with long-term consequences. With the development of radiology and pediatric surgery and orthopedics, as well as the development of modern osteosynthesis materials, concerning current scientific and professional knowledge, the outcomes are getting better, with fewer acute and chronic complications. This comprehensive review aims to provide clinicians current knowledge about pediatric elbow fractures and dislocations so that in daily practice they have as few doubts as possible with the best possible treatment outcomes.

Serial Post-Operative Radiographs in Surgically Managed Pediatric Supracondylar Humeral Fractures: Are They Always Required?

Objective

 Supracondylar humeral fractures are among the most common pediatric fractures that require surgical intervention when displaced. Recent attention has been directed towards the utilization of serial radiographs in the post-operative period and their effect on decision-making. This study aimed to determine the usefulness of postoperative radiographs early post-operatively, with the goal of determining the optimal frequency for these radiographs.

Methods

Pediatric patients who sustained a supracondylar humeral fracture and underwent operative intervention over a 15-year period were included in this study. Data were collected, including the baseline characteristics of the patients, fractures, and operative interventions. In addition, the time until healing, the total number of X-rays before K-wire removal, and postoperative function were evaluated.

Results

A total of 122 pediatric patients were included, with a mean age of 5.33 ± 2.93 years. Most fractures were Gartland Type III (74.6%). Most fractures healed at 4 (36.1%) and 3 weeks (35.2%) after surgery. Of the cohort, 94.3% underwent four different x-rays before wire removal, with 4.9% requiring revision surgery. All revision cases were Gartland type 3, and for all cases, the decision to revise was made within three weeks of surgery.

Conclusion

Routine post-fixation radiography should not be performed for surgically treated supracondylar humeral fractures before healing. An exception is the Gartland type 3 fracture, for which earlier imaging may be indicated.

Minimally invasive surgical technique for unstable supracondylar humerus fractures in children (Gartland type III or IV)

Background

Achieving and maintaining anatomical reduction during the treatment of pediatric humerus fractures, classified as Gartland type III or IV, presents a clinical challenge. Herein, we present a minimally invasive surgical approach using a novel and simple K-wire push technique that aids in achieving and maintaining anatomical reduction.

Methods

We reviewed data of children receiving treatment for supracondylar fractures of the humerus at our hospital between January 2016 and December 2020. Patients were divided into two groups based on the method of treatment: Group 1 was treated with the K-wire push technique, and Group 2 was treated with the standard technique as described by Rockwood and Wilkins. The medical records and radiographic images were reviewed. In total, 91 patients with Gartland types III and IV fractures were included, with 37 and 54 patients in Groups 1 and 2, respectively.

Results

The postoperative reduction radiographic parameters and Flynn scores at final follow-up were not significantly different between the two groups.

Conclusion

The minimally invasive K-wire push technique for unstable supracondylar fractures in children is a safe and effective alternative for improving reduction. Using this technique, complications can be minimized, and the requirement for open reduction can be reduced.

Management of Pediatric Supracondylar Humerus Fractures Using Lateral Cross-Wiring Technique Under Fluoroscopic Guidance

BACKGROUND

 Supracondylar humeral fractures are the most prevalent elbow fractures in pediatric patients. Current treatment modalities typically involve closed reduction and fixation using percutaneous Kirschner wires. The lateral cross-wiring technique has demonstrated favorable functional and cosmetic outcomes, thereby reducing the incidence of ulnar nerve injury.

OBJECTIVES

 This study aimed to assess the efficacy of the lateral cross-wiring technique in achieving optimal functional and cosmetic recovery while mitigating the risk of ulnar nerve injury in pediatric patients with displaced supracondylar humeral fractures.

MATERIALS AND METHODS

A prospective analysis was conducted on 48 patients who underwent lateral cross-wiring for displaced supracondylar fractures (Gartland type III, including extension and flexion types) of the humerus. Follow-up assessments were performed over a minimum period of eight months post-surgery.

RESULTS

Among the 48 patients, all demonstrated satisfactory restoration of the carrying angle and functional ability postoperatively. Notably, no iatrogenic cases of radial or ulnar nerve injury were observed during the follow-up period.

CONCLUSION

 The lateral cross-wiring technique emerges as an effective treatment option for displaced supracondylar fractures of the humerus in pediatric patients. It facilitates both functional and cosmetic recovery while concurrently reducing the risk of ulnar nerve injury, thus warranting consideration in the management of such fractures.

Preliminary fracture reduction in children with type III supracondylar humerus fractures during the COVID-19 pandemic

During the COVID-19 pandemic, the time elapsed from injury to definitive surgery necessitated delay in type III pediatric supracondylar humerus fractures. Preliminary fracture reduction was recommended in these fractures while waiting for operative treatment. The purpose of this study was to evaluate whether preliminary reduction afforded a better treatment experience and improved outcomes. A retrospective cohort analysis of 161 type III supracondylar humerus fractures compared treatment with preliminary closed fracture reduction and delayed percutaneous pin placement (110 children) to delayed combined closed reduction and pin placement (51 children) in a children's medical center. Of the preliminary reduction group, 22 (20%) required analgesic pain relief, compared to 18 (35%) in the non-preliminary reduction group ( P  = 0.037), and the preliminary reduction group had statistically less pain (assessed using the Faces Pain Scale-Revised rating) the first night after injury and the first-night post-CRPP ( P  = 0.019, P  = 0.008). Cast splitting was more frequent in the non-preliminary reduction group, 11 patients (22%) than in the preliminary reduction group, 10 patients (9%; P  = 0.029). The operative times in the preliminary reduction group were shorter ( P  < 0.001). If delay is necessary for complete repair of type III supracondylar humerus fractures, a preliminary fracture reduction with a temporary cast can be recommended, as these children will experience a more comfortable interval, with less swelling and pain, and potentially a shorter operation. Level of Evidence: Level III-therapeutic study.

The effects of postoperative malrotation alignment on outcomes of Gartland type III/IV paediatric supracondylar humeral fractures treated by close reduction and percutaneous K-wire fixation

PURPOSE

In this study, we aimed to investigate the effects of postoperative malrotation alignment on the outcomes of Gartland type III/IV paediatric supracondylar humeral fracture (SCHF) treated by close reduction and percutaneous K-wire fixation.

METHODS

Between January 2014 and December 2021, 295 Gartland type III/IV paediatric SCHFs treated by close reduction and percutaneous K-wire fixation were selected for this retrospective study. The demographic, clinical and radiographic parameters of all cases were collected. The lateral rotation percentage (LRP) was measured on X-rays to evaluate postoperative malrotation alignment of the fracture. All cases were categorized into 4 groups according to LRP: LRP ≤ 10% (210, 71.2%), 10% < LRP ≤ 20% (41, 13.9%), 20% < LRP ≤ 30% (26, 8.8%) and LRP > 30% (18, 6.1%). The carrying angle, ranges of multidirectional motions, Mayo Elbow Performance Score (MEPS) and Flynn's Standard Score (FSS) of the injured elbow were assessed 6 months postoperation and compared among different groups. ROC analysis based on LRP and the excellent/good rate of FSS was performed to determine the acceptable maximum degree of postoperative malrotation alignment.

RESULTS

There was no difference in the demographic characteristics (age, sex, injured side and fracture type), postoperative Baumann angle, carrying angle or range of forearm rotation among the 4 groups (P > 0.05). The operation time and time from operation to K-wire removal were longer in the 20% < LRP ≤ 30% and LRP > 30% groups than in the LRP < 10% and 10% < LRP ≤ 20% groups (P < 0.001). The shaft condylar angle, range of elbow flexion, MEPS and FSS of the injured elbow 6 months postoperatively were lower in the 20% < LRP ≤ 30% and LRP > 30% groups than in the LRP < 10% and 10% < LRP ≤ 20% groups (P < 0.001). ROC analysis based on LRP and the excellent/good rate of FSS showed an area under the curve of 0.959 (95% CI 0.936-0.983), with a cutoff value of 26.5%, sensitivity of 95.3% and specificity of 90.1%.

CONCLUSION

A certain degree of residual malrotation alignment deformity of the SCHF may reduce the shaft condylar angle and extend the time from operation to removing the K-wire and affect elbow function, especially the range of elbow flexion. The acceptable maximum degree of residual malrotation deformity expressed as the LRP value was 26.5%.

Is Lateral Onset Cross Pin Technique Strong Enough? A Biomechanical Study

Objectives

It is aimed to compare biomechanically the 3 different pin techniques and the lateral onset cross-pinning (LXP) technique in supracondylar humeral fractures.

Methods

Biomechanical testing was performed on 52 synthetic humeriFour pin configurations techniques were tested: crossed pins (XP), 2 lateral pins (2LP), 3 lateral pins (3LP), and LXP technique. Biomechanical testing was performed on Shimadzu Autograph measuring machine. Each pin configuration was tested in a total of 13 humeri: 4 in varus bending, 4 in valgus bending, and 5 in flexion bending. Displacement (mm), and load (N) data were sampled at 10 Hz during each test.

Results

Varus values were statistically lower in 2 LP group comparing to XP, 3 LP, LXP groups (p=0.01, p=0.02, p=0.012, consequently). Flexion load values statistically lower in 2 LP group comparing to XP, 3 LP, LXP groups (p=0.03, p=0.001, p=0,031, consequently). There was no difference between the groups in terms of valgus values (p>0.05).

Conclusion

LXP technique is biomechanically similar to the traditional XP technique. In situations where orthopedic surgeons choose to use medial pins in addition to lateral pins such as distal humerus fractures with medial-sided defects.

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.

How Kirschner Wires Crossing Each Other at the Fracture Site Affect Radiological and Clinical Results in Children With Gartland Type 3 Supracondylar Humerus Fractures?

Background In this study, we compared two groups of children with Gartland Type 3 supracondylar humerus fractures with respect to the crossing point of Kirschner wires (K-wires) in terms of radiological and clinical results after closed reduction and fixation with the crossed-pin technique. We hypothesized that even if medial and lateral pins cross each other at the fracture line, satisfactory radiological and clinical results would be achieved with the crossed-pin technique. Methodology A total of 59 patients with Gartland extension Type 3 supracondylar humerus fractures who underwent closed reduction and percutaneous crossed-pin fixation were included in the study. K-wires were crossing each other proximal to the fracture site in the proximal crossing group and at the fracture level in the fracture site crossing group. Loss of reduction, Baumann angle, shaft condyle angle, range of motion, and carrying angle were compared between the two groups. Results There were 43 males and 16 females in this study, with a mean age of 5.3±2.4 years. The average follow-up duration was 21.9 ± 5.2 weeks. In terms of loss of reduction in the coronal and sagittal planes, there was no statistical difference between the two groups. When the Baumann angle and shaft condylar angle of both groups were analyzed, no statistically significant differences were found at both early postoperative examination and final follow-up. Conclusions Although the crossing point of K-wires has been shown to be an important factor in the protection of reduction in biomechanical studies, it was not a significant factor for loss of reduction in this study. Factors except for the crossing point of K-wires may play a more important role in the outcomes of crossed-pin fixation.

Gartland type III extension supracondylar humerus fracture in a 10-year-old child. A surgical case report of an infrequent technique of medial and lateral column stabilization

INTRODUCTION AND IMPORTANCE

Supracondylar humeral fractures in children are the most common fractures of the elbow accounting for 16 % of all pediatric fractures. The treatment depends on age, the degree of displacement, and the presence of additional injuries.

PRESENTATION OF CASE

A case reports a 10-year-old girl with a Gartland type III supracondylar humeral fracture accompanied by anterior interosseous nerve neurapraxia preoperatively. The patient was treated operatively with medial and lateral column cross-pinning using four K-wires due to unsatisfactory closed reduction and lateral pinning only. Follow-up examinations performed in 1 and 6 months postoperatively revealed a 10° flexion contracture of the elbow with good functional and radiological results otherwise.

CLINICAL DISCUSSION

The main intervention was not focused on the AIN neuropraxia itself but on unsatisfactory closed reduction followed by cross-fixation with lateral pinning only. A standard anterior approach to visualize the fracture line, free interposing tissues, and perform stabilization was utilized. The unusual use of an additional medial pin formed a cross-frame to adequately support the medial cortex.

CONCLUSION

Closed reduction and percutaneous pinning are the preferred treatment options for most displaced supracondylar fractures. The open reduction via anterior approach and pinning for Gartland type III fracture gives good outcomes. Medial pinning is mandatory in particular fracture patterns and in case of unsatisfactory closed reduction. In the presented case medial and lateral column cross-pinning technique using four K-wires guaranteed no subsequent displacement on follow-up assessment and good results.

Time of surgery and surgeon level in supracondylar humerus fractures in pediatric patients: A retrospective study

BACKGROUND

Supracondylar humerus fractures account for more than 60% of all elbow fractures and about 1/5 of all pediatric fractures. Unfortunately, these fractures can be associated with risk of complications including neurovascular injuries, malunions and limb deformities. Controversy exists regarding the effect of time of surgical intervention and/or level of surgeon performing the surgery on outcome of these fractures.

AIM

To determine whether time of surgical intervention and/or surgeon level influence the outcomes of surgically managed pediatric supracondylar humerus fractures.

METHODS

We retrospectively studied 155 pediatric patients presenting with a supracondylar humerus fracture in a level 1 trauma center from January 2006 to December 2019. The data extracted included demographic data, fracture characteristics, surgical data, and follow-up outcomes. The collected data was analyzed and P values of < 0.05 were considered statistically significant.

RESULTS

Of the cohort, 11% of patients had documented post-operative complications, of which the majority occurred in surgeries performed after day time working hours and in fractures requiring open reduction. While the lowest complication rate was found in surgeries performed by pediatric orthopaedic surgeons, this did not reach statistical significance.

CONCLUSION

In pediatric patients undergoing surgery for supracondylar fractures, we found a higher complication rate when surgeries were not performed during working hours. Surgeon level and training had no significant effect on the risk of post-operative complications.

Management of displaced supracondylar fractures in children and adherence to the BOAST guideline- experience in a District General Hospital, UK

Background

Supracondylar fracture is the most common elbow fracture in children. These fractures can be associated with significant complications, including nerve injury, vascular compromise, compartment syndrome and clinical deformity. The British Orthopaedic Association Standards for Trauma (BOAST) provide clear and comprehensive guidance for managing the supracondylar fracture.

Aims

We reviewed the management of displaced (Gartland type 2 and 3) supracondylar fractures and adherence to BOAST guidelines between 1st audit and re-audit following the introduction of supracondylar assessment proforma.

Methods

We retrospectively analysed the adherence to BOAST guidelines for 103 patients operated between 2014 and 2020. Documentation of vascular status and individual nerve functions were assessed during presentation to the emergency department, immediately before surgery, and postoperatively before discharge from the hospital. We also reviewed the documentation of the K-wire's size utilised for fixation, the medial wire fixation technique, and post-fixation stability during the operation. A new supracondylar fracture assessment proforma was designed and implemented after the 1st audit as part of the quality improvement measure. During the second stage of the audit cycle, we reviewed 22 patients and used the same methodology as the first audit to analyse the data.

Results

Results: We found significant improvements in the documentation of capillary refill time from 65 % to 95.5 % (p = 0.0038), radial pulse from 59.2 % to 95.5 % (p = 0.0009), and documentation of individual nerve function from 37.9 % to 72.7 % (p = 0.0040) in the emergency department during 2nd stage of the audit cycle. Individual nerve function documentation by the operating team immediately before surgery changed from 42.7 % to 50 %. The use of 2 mm K-wires improved from 53.3 % to 89.5 % (p = 0.0037) Documentation of medial wire fixation technique and post-fixation stability increased to 100 % from 82.9 % to 89.5 % from 42.7 % (p = 0.0002), respectively. Postoperatively, we noted improvement in both radial pulse and capillary refill time documentation from 27.2 % to 54.2 % (p = 0.0216) and the individual nerve function from 9.7 % to 50 % (p = 0.00005).

Conclusion

Poor adherence in stage 1 of the audit cycle to BOAST standards was significantly improved in stage 2 (Re-audit) after introducing a simple supracondylar fracture assessment proforma and focussed educational sessions.

Comparative analysis of pinning techniques for supracondylar humerus fractures in paediatrics: A systematic review and meta-analysis of randomized controlled trials

Purpose

Supracondylar humeral fractures (SCHFs) rank among the frequently observed fractures in children. Nonetheless, there exists a dearth of consensus regarding the optimal surgical approach. This meta-analysis aims to thoroughly evaluate and compare two distinct pinning techniques (cross pinning versus lateral pinning) for SCHFs, using data from Randomized controlled trials (RCTs).

Methods

Literature review was done using PubMed, CINAHL, Scopus, and The Cochrane Library for RCTs comparing the two pinning methods and providing information on at least one of the following: Loss of Baumann's angle, loss of carrying angle, elbow function assessed based on Flynn criteria, pin tract infection, and iatrogenic ulnar nerve injury. Random effect model was used to calculate standardized mean difference or Odds Ratio (OR) for the outcomes. Review Manager 5.4.1. was used to perform quality assessment and statistical analysis.

Results

A total of 22 RCTs were included. 20 studies reported data for iatrogenic ulnar nerve injury, the OR was calculated to be 3.76 (95% CI 1.75-8.06), showing a significantly lower risk of surgical ulnar nerve injury with the lateral technique. However, no significant difference was found between the pinning techniques in regard to the other outcomes.

Conclusion

In comparison to lateral pinning, the utilization of cross pinning technique exposes the patient to a heightened susceptibility of iatrogenic nerve injury. Therefore, it is recommended that surgeons prioritize the implementation of the lateral pinning technique whenever feasible, as it offers greater protection against iatrogenic ulnar nerve injury. For the other intraoperative and postoperative outcomes, both surgical techniques yield comparable results.

Assessment and Validation of Anterior Humeral Line for Diagnosing Supracondylar Humerus Fractures in the Pediatric Population

INTRODUCTION

Pediatric supracondylar humerus fractures are commonly evaluated using the anterior humeral line (AHL) on a lateral radiograph. Rotational variations in radiographic projection are common due to child discomfort and could lead to changes in management based on where the AHL intersects the capitellum. The purpose of this study was to establish whether rotational variations in elbow rotation leads to significant changes in AHL position and whether drawing the AHL based on the distal humerus versus shaft is more tolerant to rotation.

METHODS

Fifty children with nonoperative supracondylar humerus fractures were identified with sub optimally positioned injury and well positioned follow-up lateral radiographs. The proportion of the bone anterior to the intersection of the AHL and the capitellum was measured using the humeral shaft versus distal humerus to guide position of the AHL. This process was repeated on ten pediatric humerus dry cadaveric specimens which were imaged in 5-degree rotational increments along the axis of the humeral shaft from -20 to +20 degrees.

RESULTS

AHL position correlated poorly when measured on rotated lateral radiographs of clinical patients versus non-rotated lateral radiographs when using the distal humerus as a guide (intraclass correlation coefficient 0.14), compared with when using the humeral shaft as a guide (intraclass correlation coefficient 0.81). When assessing the pediatric humerus dry cadavers between the 2 techniques, there was greater statistically significant variation in rotated positions compared with the neutral position in the distal humerus AHL measurement approach compared with the humeral shaft AHL measurement approach, with the mean AHL within the central third of the capitellum for more rotational positions when using the shaft compared with the distal humerus.

CONCLUSIONS

With rotated lateral elbow radiographs in supracondylar humerus fractures, utilizing the humeral shaft provides more consistent AHL measurements than utilizing the distal humerus, and thus drawing the line starting at the shaft of the humerus is recommended for surgical decision making.

Extra Lateral Pin or Less Radiation? A Comparison of Two Different Pin Configurations in the Treatment of Supracondylar Humerus Fracture

BACKGROUND

Closed reduction and percutaneous fixation are the most commonly used methods in the surgical treatment of supracondylar humerus fractures. The pin configuration changes stability and is still controversial. The aim of this study was to investigate the relationship between surgical duration and radiation dose/duration for different pinning fixations.

METHODS

A total of 48 patients with Gartland type 2, 3, and 4 supracondylar fractures of the humerus were randomized into two groups-2 lateral and 1 medial (2L1M) pin fixation (n = 26) and 1 lateral 1 medial (1L1M) pin fixation (n = 22). A primary assessment was performed regarding surgical duration, radiation duration, and radiation dose. A secondary assessment included clinical outcome, passive range of motion, radiographic measurements, Flynn's criteria, and complications.

RESULTS

There were 26 patients in the first group (2L1M) and 22 patients in the second group (1L1M). There was no statistical difference between the groups regarding age, sex, type of fracture, or Flynn's criteria. The overall mean surgical duration with 1L1M fixation (30.59 ± 8.72) was statistically lower (p = 0.001) when compared to the 2L1M Kirschner wire K-wire fixation (40.61 ± 8.25). The mean radiation duration was 0.76 ± 0.33 s in the 1L1M K-wire fixation and 1.68 ± 0.55 s in the 2L1M K-wire fixation. The mean radiation dose of the 2L1M K-wire fixation (2.45 ± 1.15 mGy) was higher than that of the 1L1M K-wire fixation (0.55 ± 0.43 mGy) (p = 0.000).

CONCLUSIONS

The current study shows that although there is no difference between the clinical and radiological outcomes, radiation dose exposure is significantly lower for the 1L1M fixation method.

Medial-lateral versus lateral-only pinning fixation in children with displaced supracondylar humeral fractures: a meta-analysis of randomized controlled trials

BACKGROUND

Supracondylar humeral fractures (SCHFs) are frequent in children, and closed reduction with percutaneous pin fixation remains the standard surgical treatment for displaced SCHFs. Two pinning configurations, medial-lateral crossed entry pinning (MLP) and lateral-only entry pinning (LP), are widely used, but which one is superior to another one is still debatable. This meta-analysis aimed to compare the efficacy and safety of both pinning fixation methods.

METHODS

Randomized controlled trials (RCTs) were searched on PubMed, EMBASE, Web of Science, Cochrane library and Google Scholar. Relative risk (RR) and mean difference (MD) with corresponding 95% confidence interval (CI) were calculated for radiographical outcomes, functional outcomes and complications.

RESULTS

A total of 19 RCTs comprising 1297 Gartland type II and type III fractures were included. MLP had a decreased risk of loss of reduction (RR = 0.70, 95%CI 0.52-0.94, P = 0.018) but a higher risk of iatrogenic ulnar nerve injury (RR = 2.21, 95%CI 1.11-4.41, P = 0.024) than LP. However, no significant difference was observed for incidence of ulnar nerve injury if applying a mini-open technique in MLP group (RR = 1.73, 0.47-6.31, P = 0.407). There were no differences between both groups in loss of carrying angle (MD = - 0.12, 95%CI - 0.39 to 0.16), loss of Baumann angle (MD = 0.08, 95%CI - 0.15 to 0.30), excellent grading of Flynn criteria (RR = 1.06, 95%CI 0.99-1.14, P = 0.102) and pin tract infection (RR = 0.92, 95%CI 0.50-1.70).

CONCLUSIONS

MLP is more effective in maintaining fixation, while LP is safer with respect to ulnar nerve injury. MLP with a mini-open technique reduces the risk of ulnar nerve lesion and is an effective and safe choice.

Long-Arm Splinting Versus Above-Elbow Casting for Type 1 Supracondylar Fractures of the Humerus in Children: a Randomized Controlled Trial

Type 1 supracondylar humerus (SCH) fractures tend to heal well when immobilized by above-elbow casting or long-arm splinting. There is no consensus as to whether one treatment method is more effective than the other for this injury. The purpose of this study was to compare the radiographic and functional outcomes of long-arm splinting and above-elbow casting as the definitive treatment for children with type 1 SCH fractures. The study was set up as a randomized controlled non-inferiority trial. Patients between three and 12 years old presenting with a type 1 SCH fracture were randomized into splint or cast groups, or an observational arm. Baumann's angle, functional assessment scores, and Flynn's criteria score were measured at initial injury and at six months post-injury. In total, 34 patients were enrolled in the study with 13 in the randomized arm and 21 in the observational arm. Due to lack of follow-up data at 6 months post-injury, five splint patients and 10 cast patients were included in the final cohort for data analysis. The average change in Baumann's angle at 6-month follow-up was 3° or less for each treatment arm. The splint group obtained excellent Flynn's criteria scores while the cast group reported good and excellent scores. Complications reported in the splint group included device breakdown, a conversion to above-arm cast, and significant itchiness. Preliminary findings suggest functional and radiological outcomes with splinting are non-inferior to casting; however, a larger sample size is required to more accurately compare the two modalities. This study was registered with the U.S. National Institutes of Health (ClinicalTrials.gov, #NCT01912365).

Impact of Preoperative Neuropraxia on Surgical Duration Following Pediatric Supracondylar Fracture of the Humerus: A Retrospective Cohort Study

Background  Supracondylar fractures of the humerus (SCFHs) are the most common type of elbow fracture in children. Because of the influence on functional outcome, neuropraxia is one of the most common concerns at presentation. The impact of preoperative neuropraxia on surgery duration is not extensively probed. The clinical implications of several other risk factors associated with preoperative neuropraxia at presentation may contribute to longer surgical duration of SCFH. Hypothesis  Preoperative neuropraxia is likely to increase surgery duration in patients who sustained SCFH. Patients and Methods  This is a retrospective cohort analysis. Sixty-six patients who sustained surgical pediatric supracondylar humerus fracture were included in the study. Baseline characteristics including age, gender, the type of fracture according to Gartland classification, mechanism of injury, patient weight, side of injury, and associated nerve injury were included in the study. Logistic regression analysis was performed using mean surgery duration as the main dependent variable and age, gender, fracture type according to the mechanism of injury, Gartland classification, injured arm, vascular status, time from presentation to surgery, weight, type of surgery, medial K-wire use, and afterhours surgery as the independent variables. A follow-up of 1 year was implemented. Result  The overall preoperative neuropraxia rate was 9.1%. The mean surgery duration was 57.6 ± 5.6 minutes. The mean duration of closed reduction and percutaneous pinning surgeries was 48.5 ± 5.3 minutes, whereas the mean duration of open reduction and internal fixation (ORIF) surgeries was 129.3 ± 15.1 minutes. Preoperative neuropraxia was associated with an overall increase in the surgery duration ( p  < 0.017). Bivariate binary regression analysis showed a significant correlation between the increase of surgery duration and flexion-type fracture (odds ratio = 11, p  < 0.038) as well as ORIF (odds ratio = 26.2, p  < 0.001). Conclusion  Preoperative neuropraxia and flexion-type fractures convey a potential longer surgical duration in pediatric supracondylar fracture. Level of Evidence  Prognostic III.

Fully displaced pediatric supracondylar humerus fractures: Which ones need to go at night?

BACKGROUND

Challenges remain in determining which displaced supracondylar humerus fractures are safe to postpone surgical treatment until daylight hours. The purpose of this study is to determine which characteristics can be identified to guide the timing of treatment of supracondylar humerus fractures.

METHODS

225 completely displaced Gartland extension type 3/4 supracondylar humerus fractures in healthy patients that presented between 6 am and 7 am were identified. Data were collected retrospectively. Data analysis included univariate, multivariable logistic regression and classification and regression tree analysis.

RESULTS

5% (78/225) underwent surgical treatment the night they presented, while 65% (147/225) were treated the next day. Overall complication rate was 6%, with no difference based on timing of surgery. 12% (28/225) presented with a motor nerve injury, while 6% (14/225) a "pink pulseless" extremity. Statistical analysis found the most reliable radiographic predictor to be the maximum displacement on the anterior-posterior or lateral view. Classification and regression tree analysis developed a clinical algorithm; patients with a "pink pulseless" extremity or motor nerve injury were recommended for surgery overnight, while those with an anterior-posterior or lateral view < 25 mm were recommended for surgery the next day.

CONCLUSION

This study provides guidance on the timing of treatment for displaced supracondylar humerus fractures that present overnight. We provide a simple algorithm with three key clinical predictors for timing of treatment: presence of a "pink pulseless" arm, presence of a motor nerve injury, and displacement of any cortex by at least 25 mm (anterior-posterior or lateral view). This provides a step forward to help practitioners make safer evidenced-based timing decisions for their patients.

Gartland Type IIa Supracondylar Humerus Fractures: Outcomes of Attempted Nonoperative Management

BACKGROUND

The optimal treatment of Gartland type IIa supracondylar humerus fractures remains controversial. We report the results of a series of patients with type IIa fractures who underwent closed reduction and immobilization using conscious sedation in the emergency department. Our goal was to identify variables associated with fractures that were successfully managed nonoperatively.

METHODS

This was a retrospective cohort study of pediatric patients who underwent closed reduction of Gartland type IIa supracondylar humerus fractures with the use of conscious sedation in the emergency department. Prereduction and postreduction radiographs were reviewed to determine the degree of fracture extension, anterior humeral line index, Baumann angle, and splint flexion angle. The success of closed reduction was defined as a reduction that was maintained without the need for surgical intervention.

RESULTS

A total of 54 patients (54 elbows) were included in this study. The mean overall age was 5.2±2.5 years. Following the closed reduction in the emergency department, 38 (70%) patients were successfully managed nonoperatively with casting, and 16 (30%) patients required operative intervention. The degree of fracture extension on the injury radiograph was 13.2±8.4 degrees in the nonoperative group compared with 19.8±7.5 degrees in the operative group (P=0.008). The postreduction degree of fracture extension was 3.0±3.4 degrees in the nonoperative group and 10.0±7.2 degrees in the operative group (P<0.0001). The mean anterior humeral line index on the injury radiograph was 0.34 in the nonoperative group and 0.13 in the operative group (P=0.104). The mean anterior humeral line index on the postreduction radiograph was 1.2 in the nonoperative group and 0.38 in the operative group (P=0.0002). Patient age, prereduction and postreduction Baumann angle, and the postreduction splint flexion angle did not differ significantly between groups.

CONCLUSIONS

Closed reduction under conscious sedation in the emergency department is a viable treatment option for Gartland type IIa supracondylar humerus fractures. Increasing fracture extension on injury radiographs can help predict failure of nonoperative management following closed reduction.

Pediatric Supracondylar Humerus Fracture AAOS Appropriate Use Criteria: Does Treatment at a Pediatric Level I Trauma Center Comply?

BACKGROUND

The primary purpose of this analysis was to compare supracondylar humerus fracture (SCHF) treatment patterns at a single quaternary pediatric hospital relative to the American Academy of Orthopedic Surgeons (AAOS) appropriate use treatment recommendation(s).

METHODS

Among all fractures included in the cohort (n=571), the observed treatment approach was evaluated relative to the AAOS "Appropriate" treatment recommendation(s). The proportion, and corresponding 95% confidence interval, of cases that agreed with the "Appropriate" treatment recommendation was estimated. Demographics and clinical characteristics among cases that were managed in accordance with the "Appropriate," "May be Appropriate," or "Rarely Appropriate" were compared.

RESULTS

All fractures were treated according to the "Appropriate," "May be Appropriate," or "Rarely Appropriate" AAOS treatment guidelines. The observed treatment among fractures included in the cohort agreed with AAOS "Appropriate" recommendations in 92.1% [95% confidence interval (CI): 89.6%-94.2%] of the cases. Fracture type differed significantly between patients treated according to AAOS "Appropriate" recommendations compared to those treated according to "May be Appropriate," or "Rarely Appropriate" recommendation.

CONCLUSIONS

The treatment approach implemented at a single level 1 trauma center was in concordance with the appropriate use criteria treatment recommendations in a significant majority of cases. Fractures not treated according to "Appopriate" recommendations were primarily type IIA injuries, and were treated with closed reduction and casting instead of the recommended closed reduction and percutaneous pinning.

Gartland type III supracondylar fracture in children: is open reduction really a dangerous choice?

BACKGROUND

Type III supracondylar fractures represent a difficult injury to treat and there is no universal consensus regarding the best treatment. The purpose of this study is to assess the incidence of complication associated with open reduction and compare open reduction vs closed reduction, in order to determine which treatment lead to better clinical and radiological outcomes. Is open reduction really associated with a higher number of iatrogenic complication and worse clinical outcomes in comparison to closed reduction?

METHODS

A total of 55 patients, affected by type III supracondylar humerus fracture, were retrospectively selected and divided into two groups according to which type of treatment they received (open reduction or closed reduction). Major complications correlated with surgical procedure, such as infections, neurovascular iatrogenic lesions, elbow stiffness and painful scarring were assessed. The treatment outcomes and clinical features were compared among the two groups. A statistical analysis to find association between the type of reduction, the restored elbow anatomy and the clinical outcomes were performed. The follow-up varies between 1 year and 7 years.

RESULTS

No major complications occurred in our series of patients. Excellent and good outcomes were reported among all 26 patients that underwent an open reduction surgery and in 23 out of the 29 patients who received a closed reduction surgery. A higher number of patients in the open reduction group presented angles with normal values; moreover 3 out of the 6 patients with unsatisfactory outcomes presented with angles not in range, underlying the presence of a connection between the restored elbow anatomy and the clinical outcomes. There were no differences among the two groups regarding the presence of complications.

DISCUSSION

Open reduction should not be considered as a first line option of treatment in any pediatric patient with a type III supracondylar humerus fracture, but in several cases open surgery must be viewed as the choice with the best outcomes not only in presence of neurovascular lesion but also in case of irreducible fracture.

Comparative Effectiveness of Closed Reduction With Percutaneous Pinning and Open Reduction With Internal Fixation in the Operative Management of Pediatric Type III Supracondylar Fractures

Background

Supracondylar fracture with total displacement is classified as Gartland type 3. The operative management for this type of fracture can be closed reduction with percutaneous pinning (CRPP) or open reduction with internal fixation (ORIF). This study aims to determine whether CRPP or ORIF led to smaller changes in Baumann’s angle, the carrying angle, loss of motion, and complication when treating pediatric supracondylar fractures.

Methodology

In a retrospective cohort design, pediatric patients presenting with supracondylar fractures at a tertiary care hospital in Bahrain between March and October of 2021 were enrolled. The collected data included age, gender, nationality, mechanism of injury, neurovascular status, type of surgery performed, follow-up period, range of motion, complications, Baumann’s angle, carrying angle, and loss of motion. The changes in Baumann’s angle, carrying angle, and reduction sufficiency were compared to the literature using Flynn’s criteria for supracondylar fractures.

Results

This study included the records of 60 patients with supracondylar fractures. In total, 28 patients underwent CRPP (group A), whereas 32 underwent ORIF (group B). A statistically significant difference (p = 0.037) between group A and group B was noted when combining the loss of carrying angle scores and the loss of motion scores to form the final Flynn score. In group A, 26 (92.8%) cases had satisfactory results; 75% of these cases were excellent or good. According to Flynn’s criteria, all patients in group B were satisfactory; 93.75% of these cases were excellent or good. The loss of motion was significantly different between the two groups (p = 0.038). The mean loss of carrying angle was significantly different between the two groups, with 5.51 ± 3.03 degrees for group A and 4.23 ± 1.85 degrees for group B (p = 0.023). The study had only two cases with unsatisfactory ratings belonging to group A.

Conclusions

In pediatric patients presenting with type 3 supracondylar fractures, when compared to CRPP, ORIF was associated with less loss of motion, less loss of carrying angle, higher overall satisfactory results according to Flynn’s criteria, and fewer complications.

A NEW FLUOROSCOPY TECHNIQUE FOR SUPRACONDYLAR HUMERUS FRACTURES

Introduction

To compare two different intraoperative fluoroscopy techniques used for closed reduction and percutaneous pinning (CRPP) in pediatric patients with supracondylar humerus fractures (SHF).

Materials and Methods

Thirty-six patients who underwent SHF surgery from May 2011 to June 2019 were included in the study. During surgery, the classical fluoroscopy method (CFM) was used in 21 patients and the new fluoroscopy method (NFM) was used in the remaining 15 patients.

Results

The mean age was 5.14±1.13 years in the NFM group and 5.38±1.36 years in the CFM group. Mean operative time was 38.14±5.92 minutes in the CFM group and 21.54±3.48 minutes in the NFM group (p=0.001), while mean fluoroscopy times were 25.65±3.91 seconds and 39.84±7.50 seconds in the NFM and CFM groups, respectively (p=0.001). The NFM and CFM groups demonstrated similar functional capacity as measured by the Mayo Elbow Score (p=0.168). Direct radiographs obtained to measure Baumann's angle also showed that the two groups had similar results (p=0.848).

Conclusions

The NFM is a reliable and successful technique as it leads to shorter operative and fluoroscopy times, as well as providing improvement in functional scores and radiological outcomes in short-term follow-up. Level of Evidence III, Therapeutic Studies-Investigating the Results Level of Treatment.

Unicolumnar Pin Fixation of Type III Supracondylar Humeral Fractures Is Associated With Over 3 Times Higher Odds of Lost Reduction

OBJECTIVES

To compare the rate of lost reduction between 2 groups of non-age-segregated type III supracondylar humeral fracture patients: a unicolumnar versus bicolumnar fixation group.

DESIGN

Retrospective cohort study.

SETTING

Pediatric Academic Trauma Center.

PATIENTS

We identified 257 patients with type III supracondylar humerus fractures from surgical billing records over a 5-year period. There were 183 patients identified with bicolumnar fixation (71.2%) and 74 patients identified with unicolumnar fixation (28.8%).

INTERVENTION

Closed reduction percutaneous pinning of the distal humerus.

MAIN OUTCOME MEASURES

The primary outcome measure was difference in rate of lost reduction between patients with bicolumnar (lateral and medial column) and unicolumnar (lateral column only) fixation (Fig. 1). The reduction and fixation at the time of fluoroscopy was assessed using the Baumann angle, Gordon index, and anterior humeral line. Loss of reduction was assessed at time of healing, defined by a Baumann angle change ≥10 degrees and Gordon index of ≥50% (Fig. 2).

RESULTS

There were 183 patients with bicolumnar fixation and 74 patients with unicolumnar fixation included in the study (average age 5.8 years; range, 2-14 years). The rate of lost reduction in patients with bicolumnar fixation was 6.01% (11/183), whereas 17.57% (13/74) of patients with unicolumnar fixation experienced lost reduction. These rates were significantly different (P = 0.008) with a 3.3 times higher odds (95% confidence interval = 1.3-8.6) of lost reduction with unicolumnar fixation.

CONCLUSIONS

There is a statistically significant increase in the rate of supracondylar fracture loss of reduction for patients with unicolumnar fixation when compared with bicolumnar fixation.

Learning Curve of Closed Reduction and Internal Fixation for Supracondylar Fractures of the Humerus in Children

BACKGROUND

This study aimed to identify the threshold for success in supracondylar humeral fracture surgery by describing the learning curve for beginners and exploring the relationship between the learning curve and the prognosis of supracondylar fractures of the humerus.

METHODS

Surgical information was collected of the first 100 humeral fractures treated by four pediatric orthopedic surgeons. The relationship between operation time, wire placement success rate, and surgical experience was determined using the restricted cubic strip (RCS). The inflection point in the curve and other risk factors that may affect fracture prognosis were collected and subjected to multiple logistic regression to clarify the relationship between the learning curve and prognosis of supracondylar fractures of the humerus. After the training, the four fresh surgeons were interviewed in the form of questionnaires to get feedback from the trainees.

RESULTS

A total of 400 supracondylar fractures of the humerus from four pediatric orthopedists were included in the study. On an RCS analysis, 65 surgical experiences were the inflection point of the learning curve. Before and after these 65 surgical experiences, there were significant differences in the patients' anatomical reduction (186 vs. 122, P < 0.001), conversion to incision (33 vs. 6, P = 0.008), and supervising physician guidance (28 vs. 2, P < 0.001). In the multiple logistic regression analysis, functional recovery after supracondylar fractures of the humerus was significantly associated with surgical experience, intraoperative conversion to incision, and post-operative infection. Four surgeons and a supervisor were interviewed. They believed that self-confidence establishment requires the experience accumulation of about 30 operations. The most critical surgical technique is the reduction of fractures.

CONCLUSIONS

Although the accumulated experience of 30 operations can establish the self-confidence of trainers, fresh surgeons must accumulate experience with 65 operations to master closed reduction and internal fixation for supracondylar fractures. Surgical experience significantly impacts the post-operative recovery of patients with fractures.

Treatment and outcomes of pediatric supracondylar humeral fractures in Korle Bu Teaching Hospital

Objectives:

Supracondylar humeral fractures (SCHF) are the most common elbow injury in the pediatric population. The treatment, outcome, and health-related quality of life (HRQoL) following these injuries are described.

Methods:

Patients with SCHF who were treated depending on the fracture type were evaluated. Medical records stored in the REDCap database were reviewed to obtain information on demographics, mechanisms of injury, neurovascular status, infection rates, and postoperative complications. Outcomes were assessed using Flynn's criteria and Pediatric Quality of Life (PedsQL) version 4.0. Follow-up was for 6 months.

Results:

A total of 101 patients with a mean age of 5.2 years (SD ± 2.3) were seen. Most of the injuries occurred at home (64.3%). The left-arm (nondominant) was the most injured (62%), though 92% of patients were right hand dominant. Ninety-six percent of the fractures were the extension type. A total of 98% had satisfactory outcomes using Flynn's criteria and older patients were likely to sustain Gartland type III SCHF (P = .01). There was a significant difference in mean scores of PedsQL (all P values < .01) at 6 months.

Conclusions:

In this prospective study, the quality of life of patients following SCHF diminished at the time of the injury and returned to the population normal 6 months after. There was no significant difference in HRQoL scores between patients who presented early and those who presented late. The delayed presentation and management did not also affect the functional outcome and complications. Therefore, surgical management of these injuries after late presentation is still safe.

Efficacy of Antibiotics in Supracondylar Fractures

BACKGROUND

Controversy exists surrounding antibiotic use in the setting of pediatric supracondylar humerus fractures treated with closed reduction and percutaneous Kirschner wire (K-wire) fixation. While the reported incidence of infection in the literature is low, surgeons frequently administer preoperative antibiotics. The purpose of this study was to retrospectively review preoperative antibiotic use and incidence of infection in children with supracondylar humerus fractures treated with closed reduction and K-wire fixation. It was hypothesized that antibiotic administration will not affect the incidence of infection following this procedure.

METHODS

We performed a retrospective review of 1053 patients with supracondylar humerus fractures treated with closed reduction and K-wire fixation at 3 institutions between 2006 and 2016. Patient demographics, antibiotic administration and follow-up data were reviewed in 905 patients.

RESULTS

Of 905 patients, 755 patients received preoperative antibiotics and 150 patients did not. The incidence of infection was 2.5% (n=22) in the group that received preoperative antibiotics and 2.0% in the group that did not receive antibiotics with an overall incidence of infection of 2.4%. The difference between groups did not reach significance (P>0.5). The majority of infections were treated with oral antibiotics with or without early pin removal. Four patients, all in the preoperative antibiotic group, required surgical debridement and intravenous antibiotics.

CONCLUSIONS

Retrospective review of the incidence of infection in closed reduction and percutaneous pinning of supracondylar humerus fractures found no difference between patients who received preoperative antibiotics and those who did not receive preoperative antibiotics.

Comparison of lateral entry and crossed entry pinning for pediatric supracondylar humeral fractures: a meta-analysis of randomized controlled trials

Background

Closed reduction and pinning entry fixation have been proposed as treatment strategies for displaced supracondylar humeral fractures (SCHFs) in children. However, controversy exists regarding the selection of the appropriate procedure. Hence, this meta-analysis was conducted to compare the effect of lateral and crossed pin fixation for pediatric SCHFs, providing a reference for clinical treatment.

Methods

Online databases were systematically searched for randomized controlled trials (RCTs) comparing lateral pinning entry and crossed pinning entry for children with SCHFs. The primary endpoints were iatrogenic ulnar nerve injuries, complications, and radiographic and functional outcomes.

Results

Our results showed that iatrogenic ulnar nerve injuries occurred more commonly in the crossed pinning entry group than in the lateral pinning entry group (RR = 4.41, 95% CI 1.97–9.86, P < 0.05). However, its risk between the crossed pinning with mini-open incisions group and the lateral pinning entry group was not significantly different (RR = 1.58, 95% CI 0.008–29.57, P = 0.76). The loss of reduction risk was higher in the lateral pinning entry group than in the crossed pinning entry group (RR = 0.66; 95% CI 0.49–0.89, P < 0.05). There were no significant differences in the carry angle, Baumann angle, Flynn scores, infections, and other complications between these two groups.

Conclusions

The crossed pinning entry with mini-open incision technique reduced the loss of reduction risk, and the risk of iatrogenic ulnar nerve injury was lower than in the lateral pinning entry group. The crossed pinning entry with mini-open incision technique is an effective therapeutic strategy for managing displaced supracondylar humeral fractures in children.

Biomechanical Analysis of Sagittal Plane Pin Placement Configurations for Pediatric Supracondylar Humerus Fractures

Anterior to posterior (AP) pinning is the recommended sagittal pin configuration in divergent lateral entry coronal pinning of pediatrics supracondylar fractures. However, there was still a lack of evidence regarding alternative sagittal pins configurations. We aimed to compare the construct stiffness of alternative sagittal pin configurations by using synthetic bone models. Sixty synthetic pediatric humeri were osteotomized to create a supracondylar fracture. After the fracture reduction, all specimens were fixed in the coronal plane with divergent lateral entry pin configurations in four different patterns in the sagittal plane: AP, crossed, divergent and parallel sagittal pin configuration. Each configuration was tested with five loading patterns. The AP sagittal pin had significantly lower construct stiffness than the divergent (p = 0.003) and the parallel sagittal pin configuration (p = 0.005) in external rotation loading tests. The divergent sagittal pin had the highest construct stiffness in extension, valgus, and external rotation loads, but the parallel sagittal pin had lower construct stiffness under extension load than the divergent and crossed sagittal pin configurations. The divergent sagittal pin configuration provides greater construct stiffness than other sagittal pin configurations due to the maximal pin spreading distance at the fracture site and the pin angle lock mechanism.

Supracondylar Humerus Fractures in Older Children: Success of Closed Reduction and Percutaneous Pinning

BACKGROUND

The incidence of supracondylar humerus (SCH) fracture declines and fracture types change as children grow. Optimal treatment method is unclear in older children. The aim of the study was to determine if fracture type and configuration of distal humerus fractures changes as patients approach skeletal maturity, and to assess the success of closed reduction and percutaneous pin (CRPP) in extra-articular SCH fractures in this transitional age group.

METHODS

Inclusion criteria for this retrospective review were (1) distal humerus fractures with extension types 2 and 3, flexion type, T-type; (2) surgically managed, and (3) modified Sauvegrain score ≥1. Reviewed parameters included fracture type and configuration, grade of skeletal maturity, fixation technique, and loss of reduction. Primary analysis was to determine the distribution of fracture type and configuration with age or grade of skeletal maturity. Secondary analysis was used to determine the factors affecting treatment success of CRPP in extra-articular fractures.

RESULTS

A total of 142 patients were included (58 males and 84 females). Fracture types revealed significant changes with increased age (P=0.031) and skeletal maturity grade (P<0.005). Skeletal maturity was a better predictor of changing fracture type than chronological age. T-type fractures were only seen in patients with modified Sauvegrain score ≥6 and flexion-type fractures were only seen in patients with modified Sauvegrain score ≤4. Loss of reduction rate after CRPP was 5%. The success of CRPP was not affected by age, sex, modified Sauvegrain score, fracture type, direction of displacement, coronal fracture pattern, number of pins or medial pin use. Fracture obliquity in the sagittal plane (P=0.05), suboptimal pin spread (P<0.01), and lack of bicolumnar fixation (P<0.01) were found as statistically significant factors associated with failed CRPP.

CONCLUSION

The distribution of fracture type changed with increased age and skeletal maturity. CRPP of extra-articular fractures in older children is a reliable option regardless of the stage of skeletal maturity. Determinants of a good outcome include optimal pinning technique with adequate pin spread at the fracture site and bicolumnar fixation.

Open Supracondylar Humerus Fractures in Children

PURPOSE

Supracondylar humerus (SCH) fractures are the most common elbow fracture in children; however, they rarely occur as open injuries. Open fractures are associated with higher rates of infection, neurovascular injury, compartment syndrome, and nonunion. The purpose of this study was to evaluate the treatment and outcomes of open SCH fractures in children.

METHODS

Between 2008 and 2015, four children (1%) had open injuries among 420 treated for SCH fractures at a single center. The mean patient age was six years (range, four to eight years). Two patients had Gustilo-Anderson grade 1 open fractures and two had grade 2 fractures. Tetanus immunization was up-to-date in all. First dose of intravenous antibiotics was given on average 3hr 7min after onset of injury (range, 1hr 38min to 8hr 15min). Time from injury to irrigation and debridement (I&D) and closed reduction and percutaneous pinning (CRPP) was on average 8hr 16min (range, 4hr 19min to 13hr 15min). All patients received 24-hour intravenous antibiotics. Pins were removed at four weeks and bony union occurred by six weeks.

RESULTS

After an average follow-up period of 12 months (range, 6 to 22 months), there were no infections, neurovascular deficits, compartment syndromes, cubitus varus deformities, or range of motion losses. All outcomes were excellent according to the Flynn criteria. Due to the unstable nature of open SCH fractures, a medial pin was used in all four cases. No loss of reduction or ulnar nerve injury occurred.

CONCLUSION

 Open injuries occur in approximately 1% of all SCH fractures in children. The authors recommend urgent intravenous antibiotics, I&D, and CRPP involving a medial pin to treat open SCH fractures. Excellent outcomes based on the Flynn criteria were obtained in four cases.

Remodeling of Sagittal Plane Malunion After Pediatric Supracondylar Humerus Fractures

BACKGROUND

Pediatric supracondylar humeral fractures (SCHFs) can heal in hyperextension malunion after casting or surgical treatment. Here the authors present quantitative evidence concerning the ability of children to remodel sagittal plane malunion. Their null hypothesis was that like varus and valgus malunion, children have little capacity to remodel sagittal plane malunion after SCHFs.

METHODS

The authors performed a prospective longitudinal radiographic study of 41 children, aged 22 to 126 months, who were registered during the study interval. They calculated the percent displacement of the center of the capitellum behind the anterior humeral line (AHL) as the distance of the midpoint of the capitellum from the AHL, divided by the diameter of the capitellum, multiplied by 100. Longitudinal measurements were made using the embedded software on our institution's digital radiographic system. The primary outcome focus was the percent displacement of the center of the capitellum relative to AHL on the initial and on the latest radiograph.

RESULTS

The average initial displacement (hyperextension) of the capitellum behind the AHL for all patients was 61% (range, 23% to 134%). At an average follow-up of 21 months, 24 children (60%) had remodeled 100% the sagittal plane malunion, 12 children (30%) had remodeled such that the AHL passed through the central third of the capitellum, and 5 children (10%) had minimal or no remodeling.

CONCLUSIONS

The authors rejected their null hypothesis. Children do have the capacity to remodel radiographically measurable sagittal plane malunion of SCHFs. Children younger than 5 years of age can remodel 100% displacement of the center of the capitellum, whereas those over 8 years of age have minimal remodeling capacity.

Prevalence and Treatment Outcome of Displaced High-Long Oblique Supracondylar Humeral Fractures in Children

Aim: The treatment protocol for supracondylar humeral fracture has mainly been based only on the severity of displacement and percutaneous pinning has been recommend as a first treatment. However, a long oblique fracture line is difficult to fix by the traditional cross pinning. The purpose of this study is to assess the prevalence of high-long oblique supracondylar humeral (HLO) fracture and evaluate the surgical outcome of percutaneous pin fixation. Methods: We reviewed 690 children who had undergone an operation for the displaced supracondylar humeral fracture. HLO fracture was defined as having a fracture line starting from either cortex above the metaphyseal-diaphyseal junction and finishing at the opposite cortex around or below the olecranon fossa. Clinical and radiographic parameter outcomes were assessed. Results: There were 14 patients diagnosed with the HLO fracture (14/690) and all the patients were treated by pin fixation. The median age was 5 years 1 month (range, 2-11 years). The common mode of injury was direct contact injury to the elbow. There were 6 patients with lateral HLO fracture, and 8 patients had medial HLO type. In medial HLO type, medial pinning only was done in 3 patients due to the difficulty in lateral pin insertion. In addition, the lateral pin was not a bicortical fixation through capitellum entry in 2 patients who had it fixed by cross pinning. The final Baumann angle and lateral humero-capitellar angle were 20.5 (5-67.6) degrees and 49.3 (23.3-71.9) degrees, respectively, without statistical significance compared to the normal side. Flynn's cosmetic grade showed satisfactory results in all patients. Conclusion: The prevalence of HLO fractures was 2% in the displaced supracondylar humeral fracture. The mechanism of injury of HLO fractures may be direct contact injury. In medial HLO fractures, medial pinning is important for stability, and sometimes lateral pinning was impossible. Contrarily, lateral HLO fracture could easily be fixed by lateral-only pinning, but the correct lateral pinning is necessary because medial pinning is difficult. The HLO fracture is a difficult pattern to treat by traditional percutaneous pinning and another surgical option should be considered.

The Utility of the Early Postoperative Follow-up and Radiographs After Operative Treatment of Supracondylar Humerus Fractures in Children

BACKGROUND

Supracondylar humerus (SCH) fractures are common elbow injuries in pediatric patients. The American Academy of Orthopedic Surgeons published guidelines for the standard of care in the treatment of displaced SCH fractures, however, no recommendations for follow-up care were made. With the recent push to eliminate unnecessary radiographs and decrease health care costs, many are questioning postoperative protocols. The purpose of our study was to evaluate the utility of the 1-week follow-up appointment after closed reduction and percutaneous pinning (CRPP) of displaced SCH fractures.

METHODS

A retrospective review performed at a single institution from 2014 to 2016 included patients under 14 years of age with a closed, displaced SCH fracture treated with CRPP. Exclusion criteria included patients without complete clinical or radiographic follow-up. Variables examined included time to initial follow-up, change in treatment plan after 1-week x-rays, complications, demographics, fracture type, pin number and configuration, reduction parameters, immobilization, time to pin removal, duration of casting, and clinical outcome.

RESULTS

A total of 412 patients were divided into 2 groups based on time to initial follow-up. Overall, 368 had an initial follow-up at 7 to 10 days (group 1) and 44 at 21 to 28 days (group 2). There was no difference in age, sex, fracture type, pin configuration, or a number of pins between groups. Statistically significant findings included time to initial follow-up and days to pin removal (group 1 at 26.2 d vs. group 2 at 23.8 d), type of immobilization (group 1 with 5% circumferential casts and group 2 with 70%), and time to surgery (26.2 vs. 62.9 h, respectively). There was no significant difference in complication rates and only a 0.5% rate of change in management in group 1.

CONCLUSIONS

Early postoperative follow-up and radiographs did not change the patient outcome and might be eliminated in children with displaced SCH fractures treated with CRPP. Given the current focus of on efficiency and cost-effective care, eliminating the 1-week postoperative appointment would improve appointment availability and decrease medical cost.

Self-Mutilation of the Fingers After a Supracondylar Humerus Fracture: The Deleterious Effects of a Median Nerve Palsy: A Case Report

CASE

A toddler underwent percutaneous pin fixation for a type III supracondylar humerus fracture (SHF). At home, her cast fell off and her k-wires pulled out. Subsequently, she presented to the emergency department for biting the tip of her index finger off and chewing on her thumb and middle fingers. She was diagnosed with a median nerve (MN) palsy with associated paresthesia.

CONCLUSION

In very young children, it may be difficult to cope with the sensation of paresthesias after a MN palsy after a SHF. Self-mutilation of the fingers may be an unfortunate complication from these paresthesias.

Displaced Supracondylar Humerus Fractures in Toddlers

Gartland type III fracture is the most troublesome type of supracondylar humerus fracture. These injuries most often occur in school age children, but they are seen in pediatric patients of all ages. The goal of this study was to analyze toddlers with Gartland type III fractures to identify clinically significant differences compared with older children. A retrospective cohort study was conducted with 94 toddlers (<3 years) and 378 older children (3 to 12 years). Factors including demographics, mechanism of injury, additional injuries, location of trauma, pin configuration, postoperative complications, follow-up time, and compliance with the treatment plan were collected and compared. The study included 94 toddlers (59% girls, 2.11±0.64 years) and 378 older children (48% girls, 6.32±1.89 years), chosen at random, who were treated between 2000 and 2015. Among toddlers, fractures were more likely to occur at home (P<.001) and to be the result of suspected nonaccidental trauma (P<.001). Older children had more additional injuries (P<.001), but were no more likely to have an open fracture (P=.59) or a flexion-type fracture (P=.42). Older children were more likely to undergo open reduction (P=.03), whereas toddlers were more likely to be treated with a medial pin (P<.001). Toddlers experienced more cubitus varus (P<.001) and loss of reduction (P=.02). No difference was found in length of follow-up (P=.83) or compliance with the treatment plan (P=.11). This study provides novel insights into clinical differences between toddlers and older children with Gartland type III fractures. Knowledge of these differences can facilitate the delivery of targeted, age-specific care for patients with type III supracondylar humerus fractures. [Orthopedics. 2020;43(5);e421-e424.].

Pediatric Type II Supracondylar Humerus Fractures: Factors Associated With Successful Closed Reduction and Immobilization

PURPOSE

The debate on the treatment of type IIa supracondylar humerus fractures has yet to be resolved. The purpose of this study was to assess the factors associated with successful closed reduction and immobilization and to assess the efficacy of a novel radiographic "hourglass" angle measurement in the management of type IIa supracondylar humerus fractures within the pediatric population.

METHODS

An institutional review board-approved retrospective review of all children who underwent closed reduction and casting or splinting of an isolated type IIa supracondylar humerus fractures treated at 2 pediatric hospitals from January 1, 2009 to August 31, 2016. Analyzed radiographic parameters included Baumann angle (BA), humerocondylar angle (HCA), perpendicular distance (PD) from the anterior humeral line to the capitellum, and the hourglass angle (HGA). These parameters were measured on injury radiographs (XR), postreduction XR, and at the first and final follow-up XR. The success of closed reduction was defined as maintenance of an acceptable reduction without a secondary procedure. The interobserver reliability was calculated.

RESULTS

There were 77 elbows treated with closed reduction and long-arm cast or splint immobilization. Of those closed reductions, 76.62% of elbows (59/77) maintained their reduction alignment and did not require surgical treatment for percutaneous pinning. In this series, the BA was not significantly different following closed reduction ([INCREMENT]1.04 degrees; P=0.081); however, the PD ([INCREMENT]1.89 mm), HGA ([INCREMENT]7.38 degrees), and HCA ([INCREMENT]5.07 degrees) had significant improvement following closed reduction (P<0.001 for all). The use of procedural sedation during reduction was strongly associated with success, 83.05% (49/59) with sedation compared with 55.56% (10/18) success without sedation (P=0.025). Furthermore, fractures that underwent a secondary procedure had 6.20 degrees less HGA following a closed reduction (P=0.016) and required additional follow-up visits (P=0.0037). The success of type IIa supracondylar humerus fractures did not significantly differ based on sex (P=0.5684), laterality (P=0.6975), mechanism of injury (P>0.9999), location of care-emergency department versus clinic (P=0.1160), or type of fracture immobilization (P=0.7411). The mean HGA in normal elbows was 177.8 degrees. The interobserver reliability for HCA was poor [intraclass correlation coefficient (ICC)=0.342]; fair for BA (ICC=0.458); and excellent for both PD and HGA (ICC=0.769 and 0.805, respectively) (P<0.001 for all).

CONCLUSIONS

Improved and acceptable radiographic parameters were achieved by a closed reduction in the majority of minimally displaced type IIa fractures treated by closed reduction and immobilization in this series. HCA upon presentation was significantly greater in successful cases, and failure to improve and maintain HGA and PD following closed reduction was associated with loss of reduction. Procedural sedation during reduction was strongly associated with success. The HGA and PD were consistent parameters used to determine effective management of type IIa fractures. This study adds support for a nonoperative closed reduction under sedation with immobilization of selected type IIa supracondylar humerus fractures.

The use of a transolecranon pin joystick technique in the treatment of multidirectionally unstable supracondylar humeral fractures in children

Multidirectionally unstable supracondylar humeral fractures cause severe instability in both flexion and extension movements. The traditional closed reduction often fails to overcome this lack of stability. The aim of this study is to use a closed reduction technique with a transolecranon pin to achieve temporary stability. From 35 pediatric multidirectionally unstable supracondylar humeral fractures hospitalized between March 2012 and March 2018 at our hospital, 23 fractures (65.7%) were treated with closed reduction and percutaneous pinning (CRPP) (group 1) and the remaining twelve fractures (34.3%) were treated utilizing a transolecranon pin joystick technique of CRPP (group 2). Both groups were followed over 16 weeks. The outcomes of our analysis included surgical time, times of fluoroscopy, Baumann angle, postoperative range of motion and complications. The surgical time and times of fluoroscopy were significantly shorter for patients in group 2 when compared with group 1 (P < 0.05). All cases showed restoration of the normal anterior humeral line-capitellar relationship. However, the quality of reduction on the anteroposterior radiographic view was significantly better for patients in group 2 than that of group 1 (P < 0.05). No immediate postoperative complications were observed. The range of motion was similar in both groups during the last follow-up appointment. A transolecranon pin is a safe and effective method for closed reduction of multidirectionally unstable supracondylar humeral fractures in children. The joystick technique can shorten surgical time and improve quality of reduction with no increasing risk of complications. Level of evidence: level III.

Effectiveness of operative versus expectant management on recovery of nerve palsies in pediatric supracondylar fractures: a systematic review protocol

OBJECTIVE

The objective of this review is to evaluate the effectiveness of operative versus expectant management on recovery of nerve palsies after pediatric supracondylar fracture of the humerus or after surgery for supracondylar fracture of the humerus.

INTRODUCTION

Supracondylar humerus fractures are the most common fracture of the elbow in children. These fractures have a high risk of complications from both the trauma itself and the treatment. Up to 12% of patients will have associated nerve injury, but there is insufficient information regarding the timing of investigation of and intervention in a persistent nerve palsy. This review aims to summarize the evidence and guide clinicians regarding the timing of investigation and/or surgical intervention for persistent nerve palsies after supracondylar humerus fractures in the pediatric population.

INCLUSION CRITERIA

This review will include pediatric patients with ipsilateral upper limb nerve palsy after supracondylar fracture of the humerus or after surgery for a supracondylar fracture of the humerus without preexisting nerve palsies.

METHODS

A comprehensive database search will be undertaken in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. The trial registers to be searched will include PROSPERO and AllTrials. The search strategy will include the keywords pediatric/paediatric, supracondylar, nerve injury/palsy/palsies, fracture, and humerus. Titles and abstracts will be screened by independent reviewers for suitability against the inclusion criteria, with accepted publications then being assessed in full with data extraction, synthesis, and assessment of methodological quality, using standardized critical appraisal tools from JBI.

A Systematic Review of the Utility of Postoperative Imaging in the Management of Pediatric Supracondylar Humerus Fractures

BACKGROUND

Recently published studies call into question the clinical utility of postoperative radiographs in the management of pediatric supracondylar humerus (SCH) fractures. This topic has been addressed as part of the American Academy of Orthopaedic Surgeons Appropriate Use Criteria, although recommendations regarding serial radiographs were not included as part of the discussion. The purpose of this systematic review is to summarize the recent literature regarding the utility of postoperative radiographs as part of the management of SCH fractures.

METHODS

A systematic review of the literature published between January 1, 2000 and December 31, 2017 was conducted using PubMed/MEDLINE and SCOPUS databases to identify studies relevant to postoperative management of SCH. Eight studies met the inclusion criteria, from which data pooled estimates and an analysis of heterogeneity were calculated.

RESULTS

The pooled estimate of changes in fracture management on the basis of postoperative radiographs was 1% (0.98±0.33). Significant interstudy heterogeneity was observed with an I test statistic of 76%. Changes in fracture management included prolonged immobilization following pin removal and return to the operating room.

CONCLUSIONS

There is a paucity of articles focusing on the utility or appropriate use of postoperative radiographs in changing management of SCH fractures, one of the most common upper extremity fractures in children. There is a very low rate of change in management on the basis of imaging, and frequently authors commented that the management change could have been prompted without routine serial radiographs. The cumulate findings of these studies suggest routine postoperative radiographs after SCH fractures are infrequently associated with changes in management. Practitioners should consider postoperative protocols with the intention of identifying early postoperative alignment loss or when the complication is suspected to prevent excessive routine radiography in the management of pediatric SCH fractures.

Cost Analysis of Treating Pediatric Supracondylar Humerus Fractures in Community Hospitals Compared With a Tertiary Care Hospital

OBJECTIVE

In the current healthcare environment, providing cost-efficient care is of paramount importance. One emerging strategy is to use community hospitals (CHs) rather than tertiary care hospitals (TCHs) for some procedures. This study assesses the costs of performing closed reduction percutaneous pinning (CRPP) of pediatric supracondylar humerus fractures (SCHFs) at a CH compared with a TCH.

METHODS

A retrospective review of 133 consecutive SCHFs treated with CRPP at a CH versus a TCH over a 6-year period was performed. Total encounter and subcategorized costs were compared between the procedures done at a CH versus those done at a TCH.

RESULTS

Performing CRPP for a SCHF at a CH compared with a TCH saved 44% in costs (P < 0.001). Cost reduction of 51% was attributable to operating room costs, 19% to anesthesia-related costs, 16% to imaging-related costs, and 7% to supplies.

DISCUSSION

Performing CRPP for a SCHF at a CH compared with a TCH results in a 44% decrease in direct cost, driven largely by surgical, anesthesia, and radiology-related savings.
