Abstract
PURPOSE Lateral humeral condyle nonunion in children is a rare condition. The treatment protocol for nonunion of lateral humeral condyle remains controversial due to the potential complication. This study reports long-term functional outcomes of the nonunion of the lateral humeral condyle fracture. In addition, we identified the prognostic factors for nonunion of the lateral humeral condyle fracture. METHODS We conducted a multicentre retrospective cohort study of nonunion of lateral humeral condyle between January 1995 and December 2022. The patient's preoperative demographic information was reviewed. Potential risk factors of poor functional outcome, such as age, duration from initial injury, and fracture displacement, were retrieved. Functional outcomes at the latest follow-up visit were evaluated using the Mayo Elbow Performance Score (MEPS). Multivariable linear regression was deployed to evaluate the association of potential risk factors with the functional outcome. RESULTS A total of 63 patients from eight medical centers were included, of which 60 were surgically treated. Patients' average age was 7.3 years old, with a mean follow-up duration of seven years. All nonunion cases were successfully treated, resulting in a normalized humeroulnar angle. The rate of AVN was 16.7%. All patients reported excellent range of motion and MEPS at the latest follow-up. Multivariable linear regression demonstrated that Fracture displacement (β = -0.88, 95% CI -1.55 to -0.22, p = 0.010) and duration from initial injury (β = -0.09, 95% CI -0.17 to -0.02, p = 0.010) were statistically significant factors influencing functional outcome of lateral humeral condyle nonunion. CONCLUSIONS Initial fracture displacement and duration from the initial injury are statistically significantly associated with elbow function in lateral humeral condyle nonunion. However, the effect size for these factors is relatively small and does not reach clinical significance. Despite this, the functional outcome is excellent in all patients, with an average follow-up duration of seven years.

UNFALLCHIRURGIE (HEIDELBERG, GERMANY) 2024:10.1007/s00113-024-01432-2.

Abstract
BACKGROUND Fractures of the lateral condyle of the humerus in children are articular fractures with difficult diagnostics due to the incompletely ossified elbow joint. The aim of this study was to evaluate the method of treatment at initial presentation and to analyze the frequency of subsequent displacement during follow-up. MATERIAL AND METHOD Retrospective analysis of the frequency of primary fracture dislocation and subsequent displacement of fractures of the lateral condyle of the humerus in children under 16 years of age between 2004 and 2021. Conventional radiographs in two planes at the time of the accident and in the follow-up after 5-7 days were evaluated. RESULTS A total of 285 fractures of the lateral condyle of the humerus were evaluated. The average age was 5.3 years. Of the fractures 109 (38.3%) were directly surgically treated in cases of primary displacement and 176 fractures (61.7%) were not primarily displaced and were initially treated conservatively. During follow-up, subsequent displacement was evident in 46 fractures (26.1%). A total of 130 fractures (45.6%) were treated conservatively and 155 fractures (54.4%) were treated surgically using open joint visualization and screw osteosynthesis or K‑wire osteosynthesis. CONCLUSION Fractures of the lateral condyle of the humerus occur more frequently in a certain age group and require targeted radiological diagnostics. Nondisplaced fractures can be treated conservatively but essential radiological follow-up shows a high number of subsequent displacements, so that open surgical stabilization is often necessary.

Abstract
BACKGROUND Lateral condyle fracture of the humerus in children should be diagnosed and treated quickly to avoid the complications of malunion and varus deformity of the elbow. Worldwide, pediatric orthopedic departments experienced delays in patient diagnosis and treatment during the COVID-19 pandemic. This retrospective study from a single center in Turkey aimed to compare outcomes from early treatment, elective treatment, and delayed treatment in 140 children with lateral condyle fracture of the humerus between 2013 and 2021. MATERIAL AND METHODS In the study, 140 patients with Milch type 2 fractures were included. Patients underwent fixation with K-wires or screws after open or closed reduction. Data collected included age, sex, trauma details, surgery timing, operating conditions, perioperative issues, and rehabilitation outcomes. Fracture union and complications were monitored through clinical examinations and X-rays. Clinical outcomes were evaluated using the Mayo Elbow Performance Score (MEPS). RESULTS There were 58 patients in the early group, 52 in the elective group, and 30 in the delayed group. Surgery durations varied among the groups (P=0.000). The early and delayed groups as well as the early and elective groups had significantly different incision sizes (P=0.000 for both). The early and delayed groups and the early and elective groups had significantly different MEPS scores (P=0.002 and P=0.011, respectively). CONCLUSIONS In patients with late-presenting lateral condyle fractures, although complications increase, surgical treatment does not yield worse outcomes. Standardization of fracture management should be maintained during periods such as COVID-19.

Abstract
Lateral humeral condyle fractures are frequently seen in pediatric patients and have a high risk of unfavorable outcomes. A fall on the outstretched arm with supination of the forearm is the most common trauma mechanism. A physical examination combined with additional imaging will confirm the diagnosis. Several classifications have been described to categorize these fractures based on location and comminution. Treatment options depend on the severity of the fracture and consist of immobilization in a cast, closed reduction with percutaneous fixation, and open reduction with fixation. These fractures can lead to notable complications such as lateral condyle overgrowth, surgical site infection, pin tract infections, stiffness resulting in decreased range of motion, cubitus valgus deformities, 'fishtail' deformities, malunion, non-union, avascular necrosis, and premature epiphyseal fusion. Adequate follow-up is therefore warranted.

Abstract
Introduction Delayed presentations and nonunion of lateral condyle of Humerus (LCH) fractures in children are common. It is recommended to gain elbow movements before placing single screw for late presenting LCH fractures. We examined the efficacy of a percutaneously placed screw in delayed presenting LCH fractures and LCH nonunion in children who presented with varying degree of elbow stiffness without waiting for improvement in elbow movements. Material and Methods Sixteen children with LCH fractures presenting after six weeks of fracture, without signs of union, and with frank nonunion were treated with percutaneous placement of the cancellous screw. There was a delay of 1.5 to18 months before presenting to us. The results were assessed by Dhillon criteria. Results All the patients at presentation had flexion deformity (avg 290) and restricted flexion ((avg 1000). Successful radiological union was achieved in fifteen patients. All the patients had full recovery of extension. Fifteen patient regained full flexion and one patient has only 100 flexion restriction (p value < 0.001). At the final follow-up, fifteen patients had excellent and one had a good overall Dhillon score. There was no clinically evident varus or valgus deformity. Conclusion We could achieve union in a majority of the patients with delayed presentation and established nonunion of LCH fractures with simple percutaneous screw placement, thereby avoiding open surgery, big scar, bone grafting, and AVN of LCH. We did not wait for an improvement in elbow movements before screw fixation and still all our patients regained full elbow movements with improved Dhillon scores.

Diagnosis and Treatment of Children with a Radiological Fat Pad Sign without Visible Elbow Fracture Vary Widely: An International Online Survey and Development of an Objective Definition. CHILDREN 2022; 9:children9070950. [PMID: 35883933 PMCID: PMC9319871 DOI: 10.3390/children9070950] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/20/2022] [Accepted: 06/22/2022] [Indexed: 11/21/2022]
Abstract
Children often present at the emergency department with a suspected elbow fracture. Sometimes, the only radiological finding is a ‘fat pad sign’ (FPS) as a result of hydrops or haemarthros. This sign could either be the result of a fracture, or be due to an intra-articular haematoma without a concomitant fracture. There are no uniform treatment guidelines for this common population. The aims of this study were (1) to obtain insight into FPS definition, diagnosis, and treatment amongst international colleagues, and (2) to identify a uniform definition based on radiographic measurements with optimal cut-off points via a receiver operating characteristic (ROC) curve. An online international survey was set up to assess the diagnostic and treatment strategies, criteria, and definitions of the FPS, the probability of an occult fracture, and the presence of an anterior and/or posterior FPS on 20 radiographs. Additionally, the research team performed radiographic measurements to identify cut-off values for a positive FPS, as well as test–retest reliability and inter-rater reliability via intraclass correlation coefficients (ICC). A total of 133 (paediatric) orthopaedic surgeons completed the survey. Definitions, further diagnostics, and treatments varied considerably amongst respondents. Angle measurements of the fat pad as related to the humeral axis line showed the highest reliability (test–retest ICC, 0.95 (95% CI 0.88–0.98); inter-rater ICC, 0.95 (95% CI 0.91–0.98)). A cut-off angle of 16° was defined a positive anterior FPS (sensitivity, 1.00; specificity, 0.87; accuracy, 99%), based on the respondents’ assessment of the radiographs in combination with the research team’s measurements. Any visible posterior fat pad was defined as a positive posterior FPS. This study provides insight into the current diagnosis and treatment of children with a radiological fat pad sign of the elbow. A clear, objective definition of a positive anterior FPS was identified as a ≥16° angle with respect to the anterior humeral line.
