Abstract
OBJECTIVES To assess the treatment and outcomes of supracondylar humeral fractures (SHFs) in children older than 10 years of age at the time of injury. METHODS The study analyzed clinical data from 60 patients who sustained SHF, all over the age of 10 years, were analyzed. The patients included 49 males and 11 females with a mean age of 10.9 ± 0.9 years (range, 10 to 14.5). All patients underwent surgical treatment under general anesthesia. Closed reduction (CR) and percutaneous fixation were the primary treatment, with open reduction and internal fixation being employed only in cases CR was unsuccessful. The study assessed the healing of fractures by measuring the radiographic angles, including the carrying angle (RCA), Baumann's angle (BA), and metaphyseal-diaphyseal angle (MDA) on anteroposterior radiographs of the elbow joint. In addition, the study evaluated whether the anterior humeral line (AHL) appropriately passed through the middle third of the capitellum. The final follow-up visit used the Mayo Elbow Performance Index score (MEPI) and Flynn's criteria to analyze the recovery of elbow function. RESULTS There were 15 (25%) SHF type II, 17 (28.3%) type III and 28 (46.7%) type IV. Of the 60 patients, 56 (93.3%) underwent successful CR, whereas 4 (6.7%) required open reduction and internal fixation because of an unsuccessful CR. The final follow-up showed the average BA as 72° ± 5.3°, the average MDA as 88.3° ± 2.8°, and the average RCA as 9.6° ± 3.9°. The AHL bisected accurately the capitellum in 59 cases (98.3%). The average range of elbow flexion-extension was 146.6° ± 8.6°, whereas the average MEPI score was 99.9 ± 0.6; 98.3% (n=59) were rated as excellent and 1.7% (n=1) were rated as good. According to Flynn's criteria, 86.7% had an excellent outcome (n=52), 10% had a good outcome (n=6), and 3.3% had a poor outcome (n=2). Only 1 patient (1.7%) experienced redisplacement. Eight cases of nerve injury were reported, with 7 involving the radial nerve and 1 involving the ulnar nerve; all resolved spontaneously. CONCLUSIONS CR and percutaneous fixation have been shown to be effective in treating SHF in 93.3% of children aged 10 years old and older at the time of injury, with favorable radiographic and functional outcomes and a low risk of secondary displacement. Open reduction should only be considered when CR is ineffective.

Abstract
There are several methods for the assessment and follow-up of reduction of supracondylar humerus fractures, which offer the possibility of evaluation in different planes. The Gordon lateral rotation index (GLRI) is one of the methods used to assess the axial plane. This study aims to evaluate the validity, reliability, and applicability of the GLRI to assess rotational alignment. The study included 50 patients with Gartland type 3 supracondylar humerus fracture. After closed reduction, fixation with 2 lateral pins and 1 medial pin was applied to all patients. Eight observers made measurements using follow-up radiographs in the early postoperative period and at the 3rd week. Gordon lateral rotation percentage (GLRP) significantly decreased from baseline to week 3 in all participants (P < 0.01). When the intraclass correlation coefficient (ICC) between the GLRP measurements of the observers in the early postoperative period was examined, a moderate agreement of 0.453 was seen between measurements of the observers (ICC = 0.453; P = 0.001; P < 0.01). When the ICC between the 3rd week GLRP measurements of the observers was analyzed, poor agreement of 0.294 was seen (ICC = 0.294; P = 0.001; P < 0.01). The GLRI has moderate validity, applicability, and reliability in the early postoperative period, and low validity, applicability, and reliability in the follow-up period. Consequently, GLRI is an objective method that can be used to assess rotational alignment in the early postoperative period of supracondylar humerus fractures. It is, however, not recommended for follow-up periods.

Abstract
OBJECTIVES The study aimed to determine relevant radiographic lines and angles of children's elbow. METHODS DESIGN A retrospective cross-sectional study. SETTING Tertiary pediatric trauma center. PATIENT SELECTION CRITERIA X-rays of healthy children's elbows 0-18 years of age in whom the radiographic image of the elbow in 2 projections was read without signs of fracture and possible indirect signs of fracture, whereas the exclusion criterion was a clearly visible poor image projection. OUTCOME MEASURES AND COMPARISONS Gender, age [patients were divided into 6 groups-group 1 (0-3 years), group 2 (4-6 years), group 3 (7-9 years), group 4 (10-12 years), group 5 (13-15 years), group 6 (16-18 years)], side, intersection of the radiocapitellar line in the anteroposterior (AP) projection, intersection of the radiocapitellar line in the lateral projection, intersection of the anterior humeral line, Baumann angle, carrying angle, lateral capitellohumeral angle, shaft condylar angle, intersection of the coronoid line and radioulnar overlap. RESULTS Two hundred elbows were evaluated. The radiocapitellar line in AP and lateral projections passed through the middle third of the capitellum in 74.5% and 93%, respectively. The anterior humeral line passed through the middle third of the capitellum in 88.5% of cases. When observing the proportion of radiocapitellar lines passing through the middle third of the capitellum in the AP, with increasing age an increasing proportion of lines pass through the middle third of the capitellum [from 8.3% in group 1 (0-3 years) to 94.1% in group 6 (16-18 years), P = 0.001] and lateral projection (from 50% in group 1%-100% in group 6, P = 0.023) and anterior humeral line (from 25% in group 1%-100% in group 6, P = 0.0001). The mean Baumman angle, carrying angle, lateral capitellohumeral angle, shaft condylar angle were 71.59 degrees, 10.97 degrees, 50.84 degrees, and 55.31 degrees, respectively. With age, the shaft condylar angle records the greatest increase (from 41.6 degrees in group 1-68.2 degrees in group 6, P = 0.000). A correlation was observed between Baumann angle and carrying angle (r = -0.674) and between Baumann angle and radioulnar overlap (r = 0.542). CONCLUSIONS Considering the anatomical variability of children's elbow, radiologic measurements and their interpretation, in the context of timely diagnostics, must be approached with great caution, especially in younger age groups, because it is with them that the largest proportion of lines and angles do not follow established principles. LEVEL OF EVIDENCE Diagnostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Current literature on pin migration is inconsistent and its significance is not understood. We aimed to investigate the incidence, magnitude, predictors, and consequences of radiographic pin migration after pediatric supracondylar humeral fractures (SCHF). We retrospectively reviewed pediatric patients treated with reduction and pinning of SCHF at our institution. Baseline and clinical data were collected. Pin migration was assessed by measuring the change in distance between pin tip and humeral cortex on sequential radiographs. Factors associated with pin migration and loss of reduction (LOR) were assessed. Six hundred forty-eight patients and 1506 pins were included; 21%, 5%, and 1% of patients had pin migration ≥5 mm, ≥10 mm, and ≥20 mm respectively. Mean migration in symptomatic patients was 20 mm compared to a migration of 5 mm in all patients with non-negligible migration ( P < 0.001). Pin migration > 10 mm was strongly associated with LOR [odds ratio (OR) = 6.91; confidence interval (CI), 2.70-17.68]. Factors associated with increased migration included increased days to pin removal ( β = 0.022; CI, 0.002-0.043), migration outwards versus inwards ( = 1.02; CI, 0.21-1.80), and BMI > 95th percentile (OR = 1.63; [1.06-2.50]). Factors not associated with migration included cross-pinning, number of pins, and fracture grade. In summary, we identified a 5% incidence of radiographic pin migration ≥ 10 mm and determined the factors associated with it. Pin migration became radiographically significant at >10 mm where it was strongly associated with LOR. Our findings contribute to the understanding of pin migration and suggest that interventions targeting pin migration may decrease the risk of LOR.

Abstract
BACKGROUND In supracondylar humerus fractures (SCHF), the most frequently used method to calculate rotation is the Gordon lateral rotation percentage (GLRP) defined by Gordon et al. However, this technique includes only typical fractures (49%-80% of all fractures) from the Johns Hopkins (J-H) fracture classification system. PURPOSE The aim of the study was to investigate (1) is Gordon criteria useful for John Hopkins subgroups of supracondylar fractures and (2) is Gordon criteria affected by internal and external rotation. MATERIAL AND METHODS This study was designed using four pediatric left humerus bones obtained from the Sawbone© company. For each bone, an osteotomy was made to mimic each of the J-H coronal fracture patterns. The cut bones were placed in a wooden rotation apparatus. The GLRP measurements were taken by five blinded observers. RESULTS In the repeated measurements of the observers, <20° rotation typical and <30° medial oblique and lateral oblique fracture pattern were measured as within the limits of an acceptable amount of rotation according to the Gordon criteria. However, for high fracture pattern (HFP), ≤30° internal rotation and <60° external rotation were determined to be within the acceptable rotation criteria according to the Gordon criteria. CONCLUSIONS All fracture patterns have different characteristics; however, based on the data of this study, the Gordon criteria can be used safely for typical, medial oblique, and lateral oblique fracture patterns but it is necessary to lower the acceptable rate of 50% for HFP.

Abstract
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.

Abstract
Objective The incidence of open reduction and internal fixation (ORIF) in flexion-type supracondylar humerus fractures (SCHF) in children is significantly higher than that of extension-type fractures. This study aimed to identify risk factors for ORIF in flexion-type SCHF. Methods One hundred seventy-one patients with Wilkins type III flexion-type SCHF from January 2012 to December 2021 were retrospectively enrolled in a tertiary paediatric hospital. Patients were divided into ORIF group versus closed reduction and internal fixation (CRIF) group. Then, patients data of age, sex, injury side, obesity, deviation of displacement, fracture level, rotation, nerve injury, and delay from injury to surgery were reviewed. Univariate analysis and multivariate logistic regression were used to identify independent risk factors and odds ratios (OR) of ORIF. Results Overall, 171 children with type III flexion-type SCHF were analyzed (average aged 7.9 ± 2.8 years). Displacement was lateral in 151 cases, medial in 20. 20 cases had combined ulnar nerve injury. The failed closed reduction rate was 20%. Univariate analysis indicated age, distal fracture fragment rotation, and ulnar nerve injury were significantly associated with ORIF. (P = 0.047, P = 0.009, and P = 0.001, respectively). Multivariate logistic regression analysis showed that distal fracture fragment rotation (OR, 3.3; 95%CI:1.1–9.5; P = 0.028) and ulnar nerve injury (OR, 6.4; 95%CI:2.3–18.3; P = 0.001) were independent risk factors; however, the age was not an independent one (OR, 1.5; 95%CI:0.6–3.5; P = 0.397) for ORIF in the Wilkins type III flexion-type SCHF. Conclusion Distal fracture fragment malrotation on initial x-rays and ulnar nerve injury were significant risk factors for ORIF in Wilkins type III flexion-type SCHF. Surgeons should prepare tourniquets or other open reduction instruments when treating these types of fractures.

Abstract
INTRODUCTION The supracondylar humerus fracture (SCHF) is one of the most common pediatric injuries. Highly displaced fractures can be very challenging. If closed reduction fails, the therapy algorithm remains controversial. MATERIALS AND METHODS In total, 41 patients (21 boys and 20 girls) with irreducible Gartland type III SCHF, treated with open reduction through three different approaches and cross-pin fixation, were retrospectively evaluated. The mean follow-up was 46 months (min.: 12, max.: 83, SD: 23.9). The Mayo elbow performance score (MEPS) as well as the quick disabilities of arm, shoulder and hand (qDASH) score were used to assess the functional outcome. Baumann's angle and the anterior humeral line (AHL, Roger's line) were obtained from follow-up radiographs. Time to surgery, postoperative nerve-palsy, rate of revision surgery, and complication rate were examined. RESULTS Two revision surgeries were reported. One due to inadequate reduction and one due to secondary loss of reduction. In this context, the AHL was a sufficient tool to detect unsatisfactory reduction. According to the MEPS the functional outcome was excellent (> 90) in 37/41 patients and good (75-89) in 4/41 at the final visit. Fair or poor results were not documented. The qDASH score was 1.8 (min.: 0, max.: 13.6, SD: 3.4). There were no significant differences between the utilized surgical approaches. An iatrogenic injury of the ulnar nerve was not reported in any case. Overall, one heterotopic ossification without impairment of the range of motion and one preliminary affection of the radial nerve were documented. CONCLUSION In the rare case of an irreducible SCHF, an anatomical reduction can be achieved by open approaches with excellent functional outcome and a high grade of patient satisfaction. All described open approaches can be utilized with a high safety-level.

Abstract
The objective of this study was to understand postoperative resorption of the anterior osseous fragment following closed reduction and percutaneous pinning (CRPP) of pediatric supracondylar humerus fractures and its effect on final range of motion (ROM). Eighty-six patients that underwent CRPP had sagittal and or axial plane deformities resulting in an anterior fragment. Humerocapitellar angle (HCA), anterior humeral line (AHL) and angle of rotation (AoR) were measured. A total of 11 (12.8%) patients failed to resorb the anterior fragment, 10 (90.9%) had satisfactory ROM. HCA initially was acceptable in 40 (46.5%) patients, and 37 (92.5%) demonstrated acceptable ROM. Final HCA was acceptable in 44 (51.2%) patients and 42 (95.4%) had acceptable final ROM. AHL was in the anterior third of the capitellum in 35 (40.6%) patients and 33 (94.3%) had acceptable ROM. Final AHL was in the anterior third of the capitellum in 43 (50.0%) patients and 41 (95.3%) had acceptable final ROM. No difference was found between acceptable ROM and HCA or AHL at either follow-up. Sixty-five and 21 patients had an AoR of 0° and between 23 and 36°, respectively. A total of 59 (90.7%) patients with an AoR of 0°, and 18 (85.7%) patients with an AoR of 23-36° displayed acceptable ROM. A total of 57 (87.7%) patients with an AoR of 0° and 18 (85.7%) with an AoR of 23-36° resorbed the anterior fragment. No association was found between rotational deformity and postoperative ROM or fragment resorption. Postoperative sagittal and axial plane alignment, HCA, AHL, AoR and resorption of the anterior osseous fragment does not correlate with final ROM.

Abstract
BACKGROUND After displaced supracondylar humerus fractures (SCHF) in children, residual deformities are common with cubitus varus (CV) being the clinically most visible. Distal fragment malrotation may lead to instability, fragment tilt and subsequent CV. Detection and assessment of malrotation is difficult and the fate of post-traumatic humeral torsion deformity is unknown. The aim of this study was to evaluate the incidence of humeral torsion differences in children with surgically treated SCHF and to observe spontaneous changes over time. METHODS A cohort of 27 children with displaced and surgically treated SCHF were followed prospectively from the diagnosis until twelve months after trauma. Clinical, photographic, sonographic and radiological data were obtained regularly. Differences in shoulder and elbow motion, elbow axis, sonographic humeral torsion measurement and radiological evaluation focusing on rotational spur were administered. RESULTS Six weeks after trauma, 67% of SCHF children had a sonographically detected humeral torsion difference of > 5° (average 14.0 ± 7.6°). Of those, 44% showed a rotational spur, slight valgus or varus on radiographs. During follow-up, an average decrease of the difference from 14° (six weeks) to 7.8° (four months) to 6.5° (six months) and to 4.9° (twelve months) was observed. The most significant correction of posttraumatic humeral torsion occurred in children < 5 years and with internal malrotation > 20°. CONCLUSION After displaced and surgically treated SCHF, most children had humeral torsion differences of both arms. This difference decreased within one year after trauma due to changes on the healthy side or correction in younger children with severe deformity. LEVEL OF EVIDENCE/CLINICAL RELEVANCE Therapeutic Level IV.

PURPOSE Supracondylar fractures are common injuries accounting for approximately 15% of all fractures in children with a large body of literature on this subject. METHODS This article critically appraises the available evidence to provide an overview of the treatment options including the role and timing of surgery, the geometry of wire fixation and the management of nerve and arterial injury. CONCLUSION Management decisions are based on a number of considerations particularly fracture stability. Closed reduction and percutaneous K-wire stabilisation are commonly recommended for an unstable displaced fracture. These techniques are however associated with the potential for iatrogenic neurological injury. Vascular injury is also rare but must be recognised and treated promptly to avoid significant permanent morbidity.

Abstract
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.

Abstract
Radiographic parameters are commonly used to determine the need for surgical supracondylar humeral (SCH) fracture reduction and the postoperative quality of reduction. We studied whether such parameters are correlated with mid-term patient-reported outcome (PRO) scores in pediatric patients.We retrospectively reviewed data from 213 patients (104 girls) treated surgically for Gartland type-II (n = 84) or type-III (n = 129) SCH fractures from 2008-2016. Mean (± standard deviation) age at surgery was 5.1 ± 2.1 years. Mean time from initial treatment to outcome survey completion was 5.0 ± 2.1 years (range, 2.0-10 years). We evaluated preoperative radiographs for coronal/sagittal fracture displacement, presence of impaction/comminution, Gartland classification, and rotation. Patients, parents were asked via telephone to complete the QuickDASH (Quick Disability of the Arm, Shoulder, and Hand) and PROMIS (Patient-Reported Outcomes Measurement Information System) Strength Impact, Upper Extremity, and Pain Interference questionnaires. Parents were also asked whether the previously fractured arm appeared normal or abnormal. We evaluated postoperative radiographs for coronal/sagittal deformity, Baumann angle, and rotation and classified reductions as near complete/complete or incomplete. Anterior humeral line through the capitellum, Baumann angle in the 7.5th to 92.5th percentile of the sample, or rotation ratio between 0.85 and 1.15 were considered near complete/complete reductions; all others were considered incomplete. Bivariate analysis was used to determine whether radiographic parameters and arm appearance were associated with QuickDASH and PROMIS scores.Patients with Gartland type-III fractures had significantly greater disability on the QuickDASH at follow-up compared with those with Gartland type-II fractures (P < .01). It is unknown if this statistical difference translates to clinical relevance. No other preoperative or postoperative radiographic parameter was significantly associated with PRO scores. There was no association between fractured arm appearance at follow-up and PRO scores.Radiographic parameters that are used to evaluate the need for and quality of pediatric SCH fracture reduction are not significantly associated with mid-term PROMIS and QuickDASH scores.LOE: Prognostic Level III.

Abstract
BACKGROUND Rotation of the humerus out of the coronal plane is presumed to alter the Baumann angle (BA) value. Identifying the rotational limits of the humerus at which the BA can be accurately and reliably measured will circumvent repeated radiographs and unnecessary exposure to radiation, may improve patient comfort, and save time and medical resources. METHODS A retrospective chart review was performed to identify patients under the age of 18 who underwent an elbow computed tomography (CT) scan without any humeral pathology and with an open distal humeral physis. For each patient, a 3-dimensional (3D) computerized model was generated with 30% transparency to mimic a plain radiograph. These models were rotated in 10-degree increments and the BA was measured on each position. In addition, the measurements were taken on an anteroposterior radiograph for each patient. Analysis of variance and the Pearson tests were performed to locate differences and define associations. RESULTS Fifteen 3D CT reconstructions were generated from 14 patients. The mean BA on the neutral position was found to be 72.2±3 degrees, which correlated with the 70.6±5.91 degrees measurement obtained on radiographs. The most extreme rotational positions on which the BA values were consistent with the neutral position values were +40 external rotation (70.97±7.01 degrees, P=1) and -70 degrees internal rotation (68.4±7.47 degrees, P=0.14). A negative correlation was found between the BA values and the extent at which the humerus was rotated from the neutral position. The variability of the BA between patients, implied by the SD of measurements on each position increased with increasing rotation from the neutral position (r=1, P<0.05). CONCLUSIONS On the basis of 3D CT images, the BA is the most accurate when the arm is positioned at an exact anteroposterior position. It is reliable to measure the BA when the humerus is rotated no more than +40 degrees external rotation to -70 degrees internal rotation. This range of rotation can act as an "accurate zone" and help avoiding multiple radiographs. LEVEL OF EVIDENCE Level III.

Abstract
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.

Abstract
Supracondylar humeral fractures in older children have different biomechanical characteristics and surgical outcomes when compared to the same fractures in younger children. We aimed to analyze the fracture's architecture in a large group of older children and investigate the correlation between patients' variables, fracture patterns, fixation techniques and the rate of loss of reduction (LOR). A retrospective review study was conducted. We collected the records of 240 consecutive patients aged 8-14 years that sustained Gartland type 2/3 supracondylar humeral fractures between 2004 and 2014 and were operated at our hospital. We excluded patients with intra-articular or pathological fractures. Following the radiographical analysis and chart review, we conducted a multivariable regression analysis. Fracture obliquity on the sagittal plane ( > 20°) occurred in 33% of the cases and was found to be the only factor related to LOR (P = 0.01). Gartland type 3 fractures and more than two lateral pin configuration did not correlate to fixation failure (P = 0.69 and 0.14, respectively). The incidence of flexion-type fractures (5.8%) was found to be higher than in the total pediatric population. The sagittal oblique supracondylar humeral fracture is common and is related to fixation instability and LOR. This pattern needs to be considered when investigating different pin configurations, complication rates, and biomechanical properties. Subclassifying Gartland type 2/3 supracondylar humeral fractures as 'oblique' or 'transverse' might offer more comprehensive information about the anticipated operative results, lead to applying more stable pin constructs to these fractures and allow improved outcomes following surgical fixation.

Abstract
OBJECTIVE The incomplete supracondylar fracture of distal humerus poses difficulty for diagnosis. A shaft-condylar angle and a lateral capitellohumeral angle, which can be measured from a routine lateral view of plain film of the injured elbow, may be a clue to assist in the diagnosis. Nevertheless, no literature explains about the accuracy of these angles for diagnosis. Our goal is to investigate the accuracy, sensitivity, specificity, positive predictive value and negative predictive value of the shaft-condylar angle and the lateral capitellohumeral angle for diagnosis of the incomplete supracondylar fracture. METHODS The retrospective study in tertiary care hospital was performed from January, 2014, to January, 2018. The patients aged below 15 years with elbow injury were recruited. The patients with complete fracture were excluded. The rest of the patients were divided into four groups which consisted of incomplete fracture and non-fracture group. With the shaft-condylar angle at 40° and the lateral capitellohumeral angle at 50°, the diagnostic accuracy of both angles were calculated. RESULTS A total number of patients were 53. For the SCA, the accuracy was 92%, the sensitivity was 76%, the specificity was 93%, the positive predictive value was 92% and the negative predictive value was 93%. For the LCHA, the accuracy was 70%, the sensitivity was 55%, the specificity was 72%, the positive predictive value was 67% and a negative predictive value was 72%. CONCLUSION The shaft-condylar angle less than 40° in lateral elbow film might be a useful tool for diagnosis of the incomplete supracondylar fracture in pediatric patients with elbow injury.

Abstract
PURPOSE The objective of this study was to explore whether there were any differences between the theoretical recommendations for children's supracondylar humeral fractures (CSHF) according to the American Academy of Orthopaedic Surgeons (AAOS) guidelines and the treatments they actually received in our institution. METHODS We retrospectively reviewed the medical charts and radiographs of all CSHFs at our hospital between January 2015 and December 2018. In all, 301 children meeting our inclusion criteria were identified and evaluated using the AAOS-Appropriate Use Criteria (AUC) application for supracondylar humerus fractures. Actual treatment was then compared with the treatment recommended by the AUC. RESULTS Actual operative management was undertaken in 0/58 (0%) Gartland type I fractures, 61/108 (56.5%) type II fractures and 98/135 (72.6%) type III fractures. Actual nonoperative management was undertaken in 58/58 (100%) Gartland type I fractures, 47/108 (43.5%) type II fractures and 37/135 (27.4%) type III fractures. Surgeon decisions for nonoperative treatment were in agreement with the AUC recommendations 100% of the time, whereas surgeon decisions for surgery matched the AUC recommendations 65.4% of the time. Predictors of actual operative management were age (p =0.003), fracture classification (p =0.000), associated orthopaedic injury requiring surgery (p =0.025) and anterior humeral line (AHL) not intersecting the capitellum (p =0.008). CONCLUSION We found low agreement between actual treatments and the AUC-recommended 'appropriate' treatments. The AUC favoured operative intervention more frequently largely on the basis of fracture classification while we emphasized age, fracture classification, associated orthopaedic injury requiring surgery and alignment of the AHL with the capitellum in our operative decision-making process.

Abstract
OBJECTIVES The aims of this paper were: (i) to examine the intra-observer and inter-observer reliability of the shaft-condylar angle (SCA) and the lateral capitellohumeral angle (LCHA); (ii) to study the influence of experience level on the inter-observer and intra-observer reliability; and (iii) to determine the influence of the the age of the patients on reliability. METHOD A retrospective cohort study was conducted. The study reviewed 81 elbow radiographs. The patients were aged between 2 and 13 years. All the images taken between 2000 and 2017 were independently measured by a senior pediatric orthopaedic surgeon, a pediatric orthopaedic surgeon, a pediatric orthopaedic fellow, an orthopaedic chief resident, a general practitioner, and a pediatric orthopaedic research assistant. Measurement was performed two times within a 2-week interval. Inexperienced observers (general practitioner and research assistant) were supervised by senior pediatric orthopaedic surgeons for at least 30 radiographs before performing the measurement. Inclusion criteria were as follows: (i) age 2-13 years; and (ii) no previous elbow fracture. EXCLUSION CRITERIA elbow radiographs do not show true lateral view. The intraclass correlation coefficient (ICC) was used to calculate the reliability. RESULTS The mean values of SCA and LCHA were 43° and 48°, respectively. For SCA, intra-observer reliability was excellent (ICC = 0.85) for one observer, good (range = 0.73-0.76) for three observers, and moderate (0.59) for one observer. Inter-observer reliability was moderate (0.48, 0.58), whereas the reliability categorized by age group showed excellent agreement (0.88-0.94). For LCHA, intra-observer reliability was excellent (0.84-0.89) for three observers and good (0.66-0.80) for two observers. Inter-observer reliability was moderate (0.44-0.45). Conversely, the reliability classified by age group showed excellent agreement (0.83-0.91). CONCLUSION Intra-observer reliability for LCHA and SCA were excellent to good for most observers. Inter-observer reliability was moderate for LCHA and SCA. Reliability classified by age group showed excellent to good agreement. Reliability was influenced by the level of experience, especially for non-medical staff.

Conservative versus surgical treatment of Gartland type 2 supracondylar humeral fractures: What can help us choosing? J Orthop 2019; 16:31-35.

Abstract
Background Pediatric supracondylar humeral fractures (PSHF) are most common elbow fractures among children and adolescents. While there is substantial agreement on treating type 1 and type 3 fractures (conservatively and surgically, respectively), the debate on optimal treatment of Gartland type 2 fractures is still open.We wanted to review our cases, analyzing outcomes and seeking for parameters that could help surgeons treating these injuries. Methods We retrospectively reviewed 41 patients treated with reduction and casting (group A) and matched to 38 patients treated with closed reduction and percutaneous pining (CRPP, group B) for Gartland type 2 fractures between 2009 and 2013. At a mean follow-up of more than 6 years patients were analyzed by an accurate clinical exam and evaluation scales. Radiographic parameters at time of cast or pins removal were studied too. Results There were no statistically significant differences in clinical exam and evaluation scales between groups. Two patients in group A developed a cubitus varus deformity and one patient in group B had a superficial pin-tract infection. Baumann angle (BA) was out of normal range in two cases of conservative group and anterior humeral line (AHL) bisected capitellum in 42.1% of patients in group A and 73.2% in group B (p < .05). Conclusion It is reasonable to expect satisfactory outcomes both after conservative and surgical treatment of type 2 fractures, if cornerstones of both treatments are applied. Parameters that should be focused are probably two: complications (2 cases of cubitus varus in group A versus one superificial pin-tract infections in group B) and the better trend in surgical group in regards to loss of flexion and hyperextension of the affected elbow, likely related to the other notable datum, that is the percentage of cases in which AHL bisects capitellum. We think that, in absence of vascolonervous lesions and important swelling, BA and AHL are the most important parameters that can help us choosing the optimal treatment, as clarified in the algorithm we developed. Level of evidence Level III - retrospective comparative study.
