Soft Tissue Injury Severity is Associated With Neurovascular Injury in Pediatric Supracondylar Humerus Fractures

Interfacility Transfer of Pediatric Supracondylar Elbow Fractures: Transfer by Ambulance Shows No Advantage in Speed of Transfer or Prevention of Complications

BACKGROUND

The treatment of supracondylar humerus (SCH) fractures is increasingly centralized in tertiary centers. Interfacility transfer from other facilities may occur by ground ambulance or privately owned vehicle (POV). The objective of this study was to determine if interfacility transfer by POV is equivalent in transfer time and perioperative complications compared with ground ambulance.

METHODS

This was a single-institution, retrospective study of SCH fractures with an intact pulse transferred by POV or ground ambulance. Transfer time points were collected to determine transfer time and speed. Associated injuries of ipsilateral fracture, skin at risk, and motor nerve palsy were recorded from orthopaedic documentation at the presentation. Insurance status and the Area Deprivation Index (ADI) were used as measures of socioeconomic disparity.

RESULTS

676 "urgent" Type III, IV, and flexion type SCH fractures and 167 "nonurgent" Type II SCH fractures were transferred by ambulance or POV. Open reduction was similar between urgent transfers transported by ambulance or POV (10% vs. 9%, P =0.344). There was no difference in transfer time ( P =0.391) or transfer speed ( P =0.416) between transfer groups. POV transfers were independently associated with no skin at risk (OR 2.1; 95% CI: 1.3-3.3, P =0.003), neurovascularly intact (OR 2.5; 95% CI: 1.4-4.4, P =0.001), and patients in the low (OR 1.9; 95% CI: 1.3-2.5, P =0.041) and moderate deprivation (OR 1.9; 95% CI: 1.1-3.5, P =0.034) compared with the high deprivation group. Medicaid insurance was associated with a lower odds ratio of private transport compared with commercial insurance (OR 0.54; 95% CI: 0.38-0.76, P =<0.001).

CONCLUSIONS

Interfacility transfer of nonemergent SCH fractures by privately owned vehicles has a similar speed of transfer and perioperative complication rate to transfer by ground ambulance. Our findings allow the triaging of nonemergent SCH fractures for potential interfacility transfer by privately owned vehicles and bring attention to disparities in interfacility transfer methods.

SUPRACONDYLAR FRACTURES IN CHILDREN: A SYSTEMATIC REVIEW OF TREATMENT OPTIONS

OBJECTIVE

To compare the outcomes of surgical stabilization of pediatric supracondylar humeral fractures with the use of crossed Kirschner wires versus divergent lateral pinning wires.

METHODS

This is a systematic review with meta-analysis carried out by searching the MEDLINE/PubMed, Science Direct and Scielo databases. In these, the search for journals was carried out between January and August 2023, where 695 studies were found. To assess the quality of the studies, the Jadad and the MINORS scales were used.. The selection and reading of relevant articles were carried out by the researchers and 11 studies met the selection criteria.

RESULTS

From the 11 selected studies, 963 patients who met the criteria for the surgical treatment of these fractures were grouped. After the statistical analysis, we found that the ulnar nerve injury had a higher incidence when the crossed-K wire technique was used; and the lateral fixation is safer for the ulnar nerve.

CONCLUSION

Both fixation techniques determine good functional results. However, fixation with lateral Kirschner wires proves to be safer considering the risk of iatrogenic injury to the ulnar nerve. Crossed-K wire fixation is more effective in terms of stability and maintenance of fracture reduction. Level of Evidence II, Systematic Review of Level II or Level I Studies with discrepant results.

Sequelae of childhood elbow fracture

Elbow fracture is frequent in children, and often requires surgery. There are many potential sequelae: neurovascular, ligamentous and osseous. Some are liable to be overlooked, due to young age and the cartilaginous nature of the joint. There is little bone remodeling in the elbow and displacement fracture, and especially supracondylar or lateral condyle fracture, has to be corrected rigorously, notably in older children. In case of lateral tilt in fracture of the neck of the radial head, on the other hand, remodeling is effective. Deformity in cubitus varus and cubitus valgus leads to neurological lesions and instability. Treatment should be early, with adapted surgery in expert hands. Post-traumatic stiffness is rare. Early intensive physiotherapy is unsuited to children and could worsen the stiffness due to inflammation. Lateral condyle non-union is a classic complication of fracture. Simple percutaneous screwing is a useful option. The equivalent in the medial epicondyle is well-tolerated, and simple monitoring now suffices. Late posterolateral rotational instability is a poorly known complication. It should be considered in case of cubitus varus that becomes painful after a long asymptomatic course. Radiocapitellar subluxation is seen on X-ray. Residual radial head dislocation after primary treatment (Monteggia lesion) responds well to the Bouyala technique of ulnar flexion osteotomy associated to annular ligament repair, without requiring ligament reconstruction.

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.

The Frequency and Outcomes of Nerve Palsies in Operatively Treated Supracondylar Humerus Fractures

BACKGROUND

A high index of suspicion for nerve palsy is essential in the setting of a displaced supracondylar humerus fracture (SCHF) with careful attention to the examination. We hypothesize that nerve injuries are more prevalent in higher energy type III and flexion SCHFs compared with type II fractures.

METHODS

A retrospective review was performed of 1085 operatively treated SCHFs in pediatric patients, aged 0 to 14 years, between January 1, 2015 and December 31, 2018. There were 979 patients eligible for analysis. Exclusion criteria included follow-up <3 weeks, polytrauma, pathologic fracture, and prior fracture of the ipsilateral elbow.

RESULTS

The overall rate of nerve injury was 10.6% (104/979). A significant difference in the rate of nerve palsy was identified between fracture types: 0.9% type II, 19.3% type III, and 10.7% flexion type SCHFs ( P <0.001). Median nerve palsy was the most common (n=65). An increased rate of ulnar nerve palsy was observed in flexion type SCHFs. The rate of nerve palsy was higher in the medial pin group (14.9%, P =0.035) but no significant association with iatrogenic ulnar nerve palsy was present. In type III and flexion SCHFs, operative time >60 minutes ( P =0.023) and the need for open reduction ( P =0.012) were significantly associated with postoperative nerve palsy. Referral to therapy was required in 30.8% of patients with a nerve palsy compared with 7.9% of patients without ( P <0.001).

CONCLUSION

Longer operative times, need for open reduction, and significantly higher rates of nerve palsy among type III and flexion SCHFs are best explained by the unstable nature of the fracture and greater degree of soft tissue trauma. Given prolonged duration of follow-up and more frequent need for therapy demonstrated in patients with a nerve palsy, these data can be used to improve counseling for families and patients after displaced SCHF.

Bruise Location in Supracondylar Humerus Fractures Predicts Specific Neurovascular Injuries

PURPOSE

The presence of soft tissue injury in pediatric supracondylar humerus fractures (SCHFs) has been shown to be an independent predictor of any neurovascular injury. Potentially expanding this concept, the specific neurovascular structure injured around the elbow is thought to be dependent upon the direction and magnitude of fracture displacement and subsequent soft tissue injury. Therefore, it was hypothesized that the bruise location following SCHF is indicative of the anatomic location of maximal soft tissue injury and therefore is a specific prognosticator of which neurovascular structure may be injured.

METHODS

Retrospective chart review of all SCHFs treated at a tertiary pediatric hospital from 2007 to 2017 collected information on bruise location, neurovascular injury patterns, and outcomes. Bruise location was classified as anterior, anterolateral, anteromedial, or posterior. Injury radiographs were reviewed by a blinded pediatric orthopaedic surgeon to neurovascular structure injured.

RESULTS

Of 2845 SCHFs identified, 267 (9.4%) had concomitant neurovascular injury-of which 128 (47.9%) met inclusion criteria. Among the vascular injuries, all bruising was anteromedial (28/45, 62.2%, P<0.05) or anterior (17/45, 37.8%, P>0.05). Fractures with anteromedial bruising correlated with median nerve injury (24/27, 88.9%, P<0.05), whereas fractures with anterolateral bruising correlated with radial nerve injuries (24/25, 96.0%, P<0.05). Bruising or radiographic evaluation correctly identified 60.2% and 64.1% of neurovascular injuries, respectively, whereas the combination identified 82.0% of neurovascular injuries correctly. Bruise location identified 23 neurovascular injuries not predicted by radiographic evaluation alone.

CONCLUSION

Bruise location is an important physical examination finding that can be used as an adjunct to improve the diagnostic accuracy of neurovascular injury in SCHFs in conjunction with neurovascular physical examination and radiographic evaluation. SCHFs with anterior or anteromedial bruising should raise concern for vascular injury. In addition, anteromedial bruising is predictive of a median nerve injury and anterolateral bruising is predictive of radial nerve injury. This adjunct diagnostic is particularly helpful in a noncooperative child or if performed by a clinician with limited experience in diagnosing neurovascular injuries or interpreting pediatric elbow radiographs.

A Mini-Open Approach to Medial Pinning in Pediatric Supracondylar Humeral Fractures May Be Safer Than Previously Thought

BACKGROUND

Displaced pediatric supracondylar humeral fractures (SCHFs) are stabilized after reduction by smooth pins. Although some SCHFs are biomechanically stable after lateral-only entry pinning (lateral pinning), an additional medial entry pin (cross-pinning) confers superior stabilization in some SCHFs. There is a recognized risk of iatrogenic ulnar nerve injury with medial entry pinning. The best existing evidence has estimated an iatrogenic ulnar nerve injury rate of approximately 3.4% in cross-pinning. In similar studies, the rate of iatrogenic nerve injury (all nerves) in lateral pinning is estimated at 1.9%. This study aimed to use a large, single-center, single-technique (mini-open) retrospective case series to determine the rate of iatrogenic ulnar nerve injury in cross-pinning.

METHODS

Patients undergoing percutaneous cross-pinning via the mini-open technique for SCHFs from 2007 to 2017 were retrospectively reviewed. Injury characteristics, operative variables, fixation technique, and complications, such as iatrogenic nerve injury, were recorded. Patients who underwent operative treatment at another hospital, had no postoperative follow-up, or died due to polytrauma were excluded.

RESULTS

In this study, 698 patients undergoing cross-pinning during the study period were identified. Patients treated with cross-pinning had severe fractures, including a total of 198 preoperative neurovascular injuries (28.4%), 32 patients (4.6%) with skin tenting, and 19 patients (2.7%) with open fractures. Iatrogenic nerve injury was reported in 3 cases (0.43%), all of which affected the ulnar nerve. In 2 of 3 cases of iatrogenic nerve injury, the ulnar nerve symptoms resolved at a mean follow-up of 15 weeks.

CONCLUSIONS

The mini-open approach for medial pin insertion is safer than previous estimates. Here, in the largest single-center study of cross-pinning for SCHFs, the iatrogenic ulnar nerve injury rate of 0.43% was nearly 10 times lower than estimated rates from recent meta-analyses. Considering all nerves, the iatrogenic injury rate for this cross-pinning cohort was also lower than the estimated iatrogenic nerve injury rate for lateral pinning.

Evaluating Perioperative Complications Surrounding Supracondylar Humerus Fractures: Expanding Indications for Outpatient Surgery

BACKGROUND

Supracondylar humerus (SCH) fractures are one of the most common pediatric orthopaedic injuries. Described using the Wilkins modification of the Gartland Classification system, current practice guidelines give moderate evidence for closed reduction and percutaneous pinning of type 2 and 3 injuries, but little evidence exists regarding the appropriate surgical setting for fixation. The goal of this study was to evaluate the perioperative complication profile of type 3 fractures with maintained metaphyseal contact and determine their suitability for outpatient surgery.

METHODS

Skeletally immature patients with type 2 and 3 SCH fractures treated at a single, Level-1 trauma institution from March 2019 to January 2000 were retrospectively reviewed. A total of 1126 subjects were identified. Open, concomitant injuries, incomplete physical examination, initial neurovascular compromise, flexion-type fractures, ecchymosis, skin compromise, and those managed nonoperatively were excluded. Type 3 fractures were categorized as either "3M" versus type "3" ("M" denoting metaphyseal bony contact). Demographic data, neurovascular changes, and postoperative complications were collected. Categorical variables were evaluated using χ2 or Fisher exact tests, and continuous variables analyzed using analysis of variance, with significance defined as a P-value <0.05.

RESULTS

A total of 485 patients (189 type 2, 164 type 3M, 132 type 3) met inclusion criteria. Sex and length of stay did not differ among groups. The incidence of neurovascular change between initial presentation and surgical fixation was significantly greater for type 3 fractures compared with other groups (P=0.02). No child in the 3M group had preoperative neurovascular examination changes, compared with 3 patients with type 3 injuries. When directly compared with the 3M group, type 3 fractures had a higher incidence of neurovascular examination changes that trended towards significance (P=0.08). There was no difference in postoperative complication rate between groups (P=0.61).

CONCLUSIONS

Our findings demonstrate that Gartland type 3 SCH fractures lacking metaphyseal bony contact, compared with types 3M and 2, are more likely to experience neurovascular examination changes between initial presentation and definitive surgical fixation. Type 3M fractures clinically behaved like type 2 injuries and, accordingly, could be considered for treatment on an outpatient basis.

Internal Rotation Stress Test Reduces Cross-Pinning and Improves Outcomes in Displaced Pediatric Supracondylar Humeral Fractures

Stabilization of the medial column is vital in preventing the loss of fixation and malunion in displaced pediatric supracondylar humeral fractures (SCHFs). The preferred percutaneous pin configuration for medial column fixation remains controversial between medial pinning (cross-pinning) and additional lateral-based pinning. The intraoperative internal rotation stress test (IRST) has been proposed to reliably determine the optimal fixation strategy for each unique fracture. This study evaluated the impact of implementing the IRST on both the choice of pin configuration and institution-wide complications in pediatric patients treated operatively for SCHFs.

Methods

Pediatric patients undergoing percutaneous pinning for SCHFs between 2007 and 2017 at a single center were retrospectively reviewed. The IRST was made a universal institutional practice in 2013. Patients were divided into 2 groups for analysis: (1) patients who underwent treatment before the IRST was implemented in 2013 (the pre-IRST group), and (2) patients who were treated after the IRST was implemented in 2013 (the IRST group). Subgroup analysis was completed for patients in the IRST group who were treated with cross-pinning or 3 lateral-based pins.

Results

In this study, 820 patients in the pre-IRST group and 636 patients in the IRST group were included. After the IRST implementation, the rate of loss of fixation fell from 1.2% to 0% (p = 0.003), and the reoperation rate fell from 3.3% to 0.2% (p < 0.001). No cases resulted in a loss of fixation after the adoption of the IRST. The number of patients treated with cross-pinning decreased significantly from 53.2% to 31.6% (p < 0.001) after the IRST implementation, yet cross-pinning continued to be used for more severe fractures. Complication rates within the IRST group were not significantly different (p > 0.05) between cross-pinning and 3 lateral-based pins.

Conclusions

In the largest cohort reported on to date, to our knowledge, institutional implementation of the IRST resulted in a significant reduction in the use of cross-pinning. Although the usage of cross-pinning decreased, cross-pinning was still used frequently in the most severe fractures. The IRST use also resulted in significantly fewer complications such as loss of fixation after institution-wide implementation of the IRST for treating pediatric SCHFs.

Pediatric Musculoskeletal Trauma: Upper Limb

Pediatric upper extremity injuries, acute and chronic due to overuse, are commonly encountered in the clinical setting. However, interpretation of imaging studies is often challenging in pediatric patients because of changing postnatal skeletal development and the broad spectrum of pathology that can potentially occur. This article discusses normal skeletal development and the pathomechanics of skeletal injuries in pediatric patients. It also outlines a framework for imaging as it pertains to the pediatric upper extremity, with specific emphasis on acute and chronic injuries to the shoulder, elbow, forearm, and wrist.

Manejo da fratura supracondiliana do úmero na criança

Supracondylar humeral fracture represents ∼ 3 to 15% of all fractures in children. It is the fracture that most requires surgical treatment in the pediatric population. Advances in treatment and care have contributed to a reduction in the most dramatic complication: Volkmann ischemic contracture. Nevertheless, the risks inherent to the fracture remain. Absence of palpable pulse in type-III fractures is reported in up to 20% of the cases. Careful sensory, motor, and vascular evaluation of the affected limb is crucial in determining the urgency of treatment. Older children, male patients, floating elbow, and neurovascular injury are risk factors for compartment syndrome. Medial comminution can lead to varus malunion, even in apparently innocent cases. The recommended treatment of displaced fractures is closed reduction and percutaneous pinning. Technical errors in pin placement are the main cause of loss of reduction. There is enough evidence for the addition of a third lateral or medial Kirschner wire in unstable fractures (types III and IV). Medial comminution may lead to cubitus varus even in mild displaced fractures. Based on current concepts, a flowchart for the treatment of supracondylar humeral fracture in children is suggested by the authors.

Medial tenderness revisited: Is medial ankle tenderness predictive of instability in isolated lateral malleolus fractures?

INTRODUCTION

Determining deltoid ligament incompetence in supination external rotation (SER) injuries commonly relies on stress radiography, given several studies demonstrating low predictive value of physical examination. Stress radiography can be difficult to obtain and may result in suboptimal radiographs with equivocal determination of stability. This study revisits the concept of medial ankle tenderness and its association with mortise instability.

METHODS

Patients who presented with an isolated lateral malleolus fracture underwent prospective data collection. VAS scores were recorded with palpation at the lateral malleolar fracture site, anterior deltoid ligament, and posterior deltoid ligament. Three non-weightbearing radiographs of the ankle and a gravity stress view were obtained. Statistical analysis was performed to determine a correlation between tenderness and instability defined as MCS widening > 4 mm on gravity stress x-ray.

RESULTS

51 patients met inclusion criteria. Group I (stable) and Group II (unstable) demonstrated no difference in tenderness over the lateral malleolus (p = 0.94) or anterior deltoid (p = 0.12), but patients in Group II reported significantly more tenderness over the posterior deltoid (p = 0.03). Taking the higher pain score from either anterior or posterior deltoid palpation, patients with unstable ankle fractures reported significantly more tenderness with medial palpation (p = 0.02). The relative risk of having an unstable ankle fracture with any tenderness to palpation over either the anterior or posterior deltoid ligament was 1.77 (95% CI 1.03 - 3.06, P = 0.039). When comparing no pain versus the presence of any pain with palpation medially, the sensitivity for any medial tenderness to detect an unstable ankle fracture was 0.76 (specificity 0.59, PPV 0.79, NPV 0.56).

CONCLUSION

Patients with any medial tenderness were at significantly higher risk of having an unstable SER ankle fracture in this study, but strict reliance on the presence or absence of medial tenderness without stress radiographs would lead to an unacceptable number of both false positive and false negative determinations of instability. However, our findings suggest that medial tenderness is associated with instability. The 0.79 PPV of any medial tenderness for instability may be useful to cast doubt on equivocal stress radiography and prompt surgeons to repeat stress radiography or shorten the interval for radiographic follow up.

Local Hematoma Block as Postoperative Analgesia in Pediatric Supracondylar Humerus Fractures

Purpose

Supracondylar humerus fracture (SHF) is the most common type of fracture in children. The aim of this study was to evaluate the efficacy of local hematoma block with 0.25% bupivacaine as postoperative pain control in patients with pediatric SHF who underwent closed reduction pin fixation.

Methods

We performed an institutional review board–approved, prospective cohort study of 65 patients with SHF treated with closed reduction percutaneous pin fixation. For 6 months, all patients were randomly divided into 2 groups. The treatment group (35 patients) received an intraoperative local hematoma block using 0.25% bupivacaine whereas the control group (30 patients) did not receive a local hematoma block as postoperative pain management adjuvant. After surgery, all patients were prescribed opioid pain medication. To evaluate the efficacy of the hematoma block, postoperative morphine equivalent consumption and the Faces Pain Scale–Revised (FPS-R) survey were blindly recorded during postoperative day 1. Demographic data, surgical details, clinical neurovascular examination during the hospital stay, and complications were also evaluated.

Results

Comparison of the control group with the treatment group showed similar morphine equivalent consumption and Face Pain Scale–Revised Survey results. No hematoma block-associated complications were reported.

Conclusions

The result of this study do not favor the use of local hematoma block to improve pain control and decrease the need for opioid use on postoperative day 1 in pediatric SHF after patients undergo closed reduction percutaneous pin fixation. These results can lay the foundation for future studies while suggesting new, novel opioid-free pain control strategies in patients with SHF.

Skin Puckering in a Tibial Fracture

Skin puckering is a feature observed in fractures that undergo large displacements at the time of initial injury and occur as a result of adherence of the dermal tissues to the underlying fracture fragment. Herein, we discuss the interesting case of a 47-year-old male who suffered a comminuted tibial shaft fracture which resulted in marked pretibial skin puckering prior to fracture reduction with striking corresponding images noted on computerised tomography (CT) scanning. 

Epidemiological Analysis of Displaced Supracondylar Fractures

INTRODUCTION

 Supracondylar fractures are one of the most common fracture patterns sustained by children, and one of the most common injuries requiring operative fixation. Understanding the complications associated with supracondylar fractures is vital for the practicing orthopedic surgeon. This analysis of supracondylar fractures examined the clinically important aspects including vascular injury, compartment syndrome, neurological injury, brachialis entrapment, associated injuries, and etiologies of injury. Recent advances in technology have resulted in a myriad of new forms of recreational equipment for children to play with. The purpose of this study is to compare the historical literature, the current literature, and a single surgeon's sample of supracondylar fractures. In addition, this study aims to evaluate if any changes in epidemiology or etiology have occurred due to the development of new recreational equipment.

OBJECTIVE

 The purpose of this study is to evaluate and provide a qualitative overview of the epidemiology of displaced supracondylar fractures, to compare historically reported numbers to more recent literature as well as a single surgeon sample, and to evaluate if changes in epidemiology or etiology have occurred due to the new recreational equipment that children use.

METHODS

Some 75 displaced supracondylar elbow fractures were reviewed. Data elements recorded from the electronic medical record (EMR) included patient age, gender, height, weight, handedness, date, time, location, mechanism, Gartland classification, concurrent injuries, and neurovascular status.  Results: In this study, there were 42 males and 33 females. The average age was six years. Some 70 of the 75 patients were older than the age three. One fracture was open, nine fractures had a pucker sign, seven presented with a nerve palsy, four presented without a pulse, and seven patients presented with an additional ipsilateral distal radius fracture. All fractures were the result of a fall. Falls from playground equipment resulted in 29 fractures. There were 10 from falls off of furniture, six from falls during sports, three from falls on the stairs, and three from fall off of bikes. The remaining fractures resulted from running, tripping, falling from a toy ball, sled, tree, wagon, fence, bounce house, van, deck, power wheels car, ATV, and a go-cart. Some 64 fractures were transferred from 27 different outside hospitals. Eleven fractures presented directly to the ED. Twenty-six fractures occurred during the summer, 20 occurred in the autumn, 6 occurred in the winter, and 23 occurred during the spring. Some 35 fractures occurred at home, 30 on the school grounds, four in a gymnasium, four in a park, one at a farm show, and one in a parking lot. Some 25 fractures were treated between midnight and 8 am, 16 were treated between 8 am and 5 pm, and 34 were treated between 5 pm and midnight.  Conclusion: Pediatric supracondylar fractures are common in children, and many of them require operative intervention. This study examined the most important aspects of supracondylar fractures. This update provides a look at the clinically important aspects of supracondylar fractures and compares them to previous teachings and canon. Despite the advancement and changes in recreational equipment that children are using, children are still sustaining supracondylar fractures in the most common ways including falls from playground equipment and falls from standing.

Delaying Surgery in Type III Supracondylar Humerus Fractures Does Not Lead to Longer Surgical Times or More Difficult Reduction

OBJECTIVE

To determine if delay in surgical treatment of type III supracondylar humerus fracture would affect the length of operative time.

DESIGN

Retrospective cohort study.

SETTING

Level 1 trauma center.

PATIENTS/PARTICIPANTS

This is a series of 309 modified Gartland type III supracondylar fractures treated operatively from 2011 to 2013.

INTERVENTION

Fifteen hours was defined as the cutoff between early and delayed treatment. A total of 53.7% (166/309) fractures were treated early, and 46.4% (143/309) were delayed.

MAIN OUTCOME MEASUREMENTS

Surgical time was defined as "incision start" to "incision close." Fluoroscopy time was used as a surrogate for difficulty of reduction.

RESULTS

Time from injury to operating room was shorter for high-energy fractures (fractures with soft-tissue or neurovascular injury) versus low-energy fractures (12.9 vs. 15.3 hours, P < 0.0001); however, surgical time (37.3 vs. 31.8 minutes, P = 0.004) and fluoroscopy time (54.6 vs. 48.6 seconds, P = 0.027) were longer in high-energy fractures versus low-energy fractures. Among low-energy fractures, no significant difference was detected in the surgical time between the early and delayed treatment groups or in the fluoroscopy time. In addition, there was no statistically significant difference found in the surgical or fluoroscopy time with the presence of a surgical assistant.

CONCLUSIONS

Delay in surgery did not result in a longer surgical time or more difficult reduction for type III supracondylar humerus fracture. Patients with low-energy fractures still underwent a shorter operative time even with delay from injury to surgery.

Pediatric Orthopedic Trauma: An Evidence-Based Approach

The management of pediatric fractures has evolved over the past several decades, and many injuries that were previously being managed nonoperatively are now being treated surgically. The American Academy of Orthopaedic Surgeons has developed clinical guidelines to help guide decision making and streamline patient care for certain injuries, but many topics remain controversial. This article analyzes the evidence regarding management of 5 of the most common and controversial injuries in pediatric orthopedics today.
