Neurovascular complications after supracondylar humerus fractures in children.
Ontology highlight
ABSTRACT: Background
Supracondylar fractures of the humerus are a common injury in pediatric traumatology. The most common operative therapy is closed reduction and percutaneous pinning using K-wires. Common complications associated with this entity are neurovascular lesions, especially of the brachial artery and the median nerve.Methods
We report two cases of patients treated in our trauma-center with supracondylar fracture of the humerus (AO IV°) and neurovascular complications.Results
Both patients underwent open revision and recovered completely in their further course.Conclusion
We recommend detailed neurovascular examination initially and after reposition of the fracture. The threshold for open reduction in cases of irreducible fractures should be low. In the presence of neurovascular impairment an open revision is mandatory, even months after the initial Trauma.Level of evidence: Level V (case report).

Project description:PurposeThe 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.MethodsRetrospective 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.ResultsOf 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.ConclusionBruise 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.Level of evidenceLevel IV, case series.

Project description:Background and purpose - The long-term outcome of pin-fixed supracondylar humerus fractures (SCHF) in children is not well known. We assessed the 7- to 12-year outcome in 168 children. Patients and methods - During 2002-2006, 210 domestic children (age 7 (1-14) years) with SCHF (Gartland III 79%, Gartland II 19%, and flexion type 2%) were pin fixed in Helsinki. 36 (17%) patients had a nerve palsy. Radiographic alignment was regarded as satisfactory in 81% of patients (Baumann angle (BA) within ±10? of normal range and whose anterior humeral line (AHL) crossed the capitulum). After a mean follow-up of 9 (7-12) years, 168 (80%) patients answered a questionnaire regarding elbow appearance (scale 0-10), function (scale 0-10), and pain (scale 0-10), and symmetry of range of motion (ROM) and carrying angle (CA). 65 (31%) patients also attended a clinical follow-up examination. Results - Mean subjective score for appearance was 8.7 (2-10) and for function 9.0 (2-10) (n = 168). Elbow ROM asymmetry was experienced by 28% and elbow CA asymmetry by 17% of the patients. Elbow pain was reported by 14%, and was more common in children with nerve injuries. Long-term outcome was good or excellent in 60/65 and CA in 56/65 of the follow-up visit patients using Flynn's criteria. BA exceeding normal values by 10? was associated with lower subjective outcome; AHL crossing point with the capitulum was not associated with outcome. Interpretation - Long-term subjective outcome is satisfactory with few exceptions if elbow ROM and CA are restored within 10° of the uninjured elbow. Radiographs at fracture union have little prognostic value. Nerve injuries can cause long-term pain.

Project description:BackgroundSupracondylar humerus fractures (SHF) are the second most common fracture in children and the most common fracture in children under seven years. Subtle neurovascular lesions in displaced SHF may be underdiagnosed clinically, but their sequelae can mean life-long symptoms. Here we show that color-coded duplex ultrasound (DUS) could help to identify these patients.MethodsWe reviewed records of 229 children who had recovered from SHF. Ninety patients were available for detailed questionnaires, in-depth neurovascular examinations, and DUS.ResultsIn 90 examined patients, only two had been known to have suffered from vascular complications before our study. Only one still complained spontaneously about perfusion-induced symptoms. Qualitative changes in blood flow in duplex-sonography were detectable in both. Another two patients showed similar changes in blood flow at the fracture site. Both reported load-induced pain and paresthesia on detailed inquisition when no vascular impairments had been known before. Thus, duplex-sonography identified two patients with vascular affections that had not been noticed before in routine clinical examinations.ConclusionDUS can be a sensitive tool in diagnosing vascular impairments in patients with SHF. It could reduce diagnostic insecurity, especially in anesthetized or otherwise hard to examine children, and thus help avoid the therapeutic delay that otherwise might foster life-long sequelae for the patients. More studies are needed to establish age-adjusted reference values for duplex-sonography of children's arms. Level of Evidence: Level III, Study of nonconsecutive patients (without consistently applied reference).

Project description:BACKGROUND:The treatment of supracondylar humerus fracture in children (SHFC) is associated with complications such as functional deficit, residual deformity, and iatrogenic neurological damage. The standard treatment is closed reduction and percutaneous Kirschner wire fixation with different configurations. Despite this fact, there is still no consensus on the most effective technique for the treatment of these fractures. OBJECTIVE:The aim of this systematic review will be to evaluate the effect of surgical interventions on the treatment of Gartland type II and III SHFC by assessing function, complications, and error as primary outcomes. Clinical outcomes such as range of motion and pain and radiographic outcomes will also be judged. METHODS:A systematic review of randomized controlled trials or quasi-randomized controlled trials evaluating the surgical treatment of SHFC will be carried out in the Cochrane Central Register of Controlled Trials, PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde, and Excerpta Medica Database. The search will also occur at ongoing and recently completed clinical trials in selected databases. Data management and extraction will be performed using a data withdrawal form and by analyzing the following: study method characteristics, participant characteristics, intervention characteristics, results, methodological domains, and risk of bias. To assess the risk of bias of the included trials, the Cochrane Risk of Bias Tool will be used. Dichotomous outcome data will be analyzed as risk ratios, and continuous outcome data will be expressed as mean differences, both with 95% confidence intervals. Also, whenever possible, subgroup analysis, sensitivity analysis, and assessment of heterogeneity will be performed. RESULTS:Following the publication of this protocol, searches will be run and included studies will be deeply analyzed. We hope to obtain final results in the next few months and have the final paper published by the end of 2018. This study was funded by a government-based noncommercial agency, Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP). CONCLUSIONS:This study may provide surgical treatment effects evidence for SHFC. The results will assist clinical practice by demonstrating the effectiveness and potential complications of these interventions and might serve as a reference for future clinical trials on the topic.

Project description:BackgroundThis 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.MethodsSurgical 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.ResultsA 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.ConclusionsAlthough 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.Level of evidenceLevel III.

Project description:Socioeconomic status, race, and insurance status are known factors affecting adult orthopaedic surgery care, but little is known about the influence of socioeconomic factors on pediatric orthopaedic care. The purpose of this study was to determine if demographic and socioeconomic related factors were associated with surgical management of pediatric supracondylar humerus fractures (SCHFs) in the inpatient versus outpatient setting. Pediatric patients (<13 years) who underwent surgery for SCHFs were identified in the New York Statewide Planning and Research Cooperative System database from 2009-2017. Inpatient and outpatient claims were identified by International Classification of Diseases-9-Clinical Modification (CM) and ICD-10-CM SCHF diagnosis codes. Claims were then filtered by ICD-9-CM, ICD-10-Procedural Classification System, or Current Procedural Terminology codes to isolate SCHF patients who underwent surgical intervention. Multivariable logistic regression analysis was performed to determine the effect of patient factors on the likelihood of having inpatient management versus outpatient management. A total of 7079 patients were included in the analysis with 4595 (64.9%) receiving inpatient treatment and 2484 (35.1%) receiving outpatient treatment. The logistic regression showed Hispanic (OR: 2.386, p < 0.0001), Asian (OR: 2.159, p < 0.0001) and African American (OR: 2.095, p < 0.0001) patients to have increased odds of inpatient treatment relative to White patients. Injury diagnosis on a weekend had increased odds of inpatient management (OR: 1.863, p = 0.0002). Higher social deprivation was also associated with increased odds of inpatient treatment (OR: 1.004, p < 0.0001). There are disparities among race and socioeconomic status in the surgical setting of SCHF management. Physicians and facilities should be aware of these disparities to optimize patient experience and to allow for equal access to care.

Project description:A recent study reported a higher incidence of pre-operative ulnar nerve symptoms in patients with flexion-type supracondylar fractures than in those with the more common extension supracondylar fractures and a greater need for open reduction (Kocher in POSNA paper #49 2006). We have encountered a specific pattern of flexion supracondylar fractures that often require open reduction with internal fixation (ORIF) due to entrapment of the ulnar nerve within the fracture.Medical records and X-rays from 1997 to 2005 at our children's hospital were examined to identify flexion supracondylar fractures that required open reduction. The operative reports were reviewed to identify cases that had the ulnar nerve blocking the reduction.During the 8 years examined, 1,650 supracondylar fractures had been treated by means of closed reduction and percutaneous pinning. Of these, only 1.8% or 30 cases could not be reduced closed and required open reduction internal fixation, excluding 11 open fractures. Of the 30 fractures requiring open reduction internal fixation, 24 were of the extension type needing ORIF because of interposed periosteum/muscle. The other 6 patients had flexion-type supracondylar fractures that failed closed reduction. All had a persistent medial gap at the fracture site. All 6 fractures had interposed periosteum or muscle, while in 3 cases the ulnar nerve was also entrapped within the fracture site (Figs. 1, 2)Flexion-type supracondylar fractures remain a relatively uncommon variant (2-3%) of supracondylar fractures. Recent reports have noted that open treatment of these fractures is required more frequently than for extension fractures. In our series, 20% of the open cases were flexion-type fractures and in half of these the ulnar nerve was found to be entrapped in the fracture, preventing reduction.

Project description: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).

Project description:BackgroundOutdoor play and risk-taking behaviors, including play at heights, are important to children's physical, social, and cognitive development. These aspects of play are important to consider when informing prevention policies for serious injuries that commonly occur on play structures. Supracondylar fractures of the humerus (SCH) are the most common type of elbow fractures that result from falls on an outstretched hand among healthy children. Despite being one of the leading causes of admission to the hospital and surgical intervention, the details surrounding the cause of these injuries are often not recorded. Previous research has correlated decreased overall playground safety with higher rates of SCH fractures. Play structure height and the type of undersurface have been identified as potential risk factors for severe injuries, including SCH fractures, in part due to low compliance with safety standards. This paper explores the challenges we encountered designing the study and the resulting insights and methodological modifications we made.ObjectiveThe aim of this paper is to discuss the challenges related specifically to clinical research in pediatrics and strategies developed to conduct a study that prioritizes the engagement and perspective of children and their families.MethodsTo explore the link between the severity of SCH fractures and children's behavioral, environmental, and mechanistic factors, we conducted a mixed-methods study.ResultsDuring phase 1 (the original methodology) from April 2017 to July 2018, there were 58 eligible study participants and 17 were recruited. For phase 2 (the revised methodology) between October 2018 and October 2019, there were 116 eligible participants and 47 were recruited.ConclusionsThe changes in methodology made following the first phase of data collection were effective in our ability to recruit participants. By identifying and addressing challenges pertaining to recruitment and resource limitations, we were able to collect data in a concise manner while not compromising the quality of the data and make for an easily adoptable methodology for other sites interested in participating in the study. We hope that future studies that plan to employ a similar methodology can gain insight through the methodological challenges we have encountered and the way we adapted the methodology to build a more pragmatic approach.International registered report identifier (irrid)DERR1-10.2196/21816.
