Abstract Background: The evaluation of the articular cartilage status of the distal humeral epiphysis is difficult. Ultrasound of the elbow is increasingly used to confirm the integrity of the articular cartilage of minimally displaced lateral humeral condyle fractures in children in minimally displaced fractures. The aim of this study was to assess the correlation between ultrasound with arthrography for predicting the integrity of the cartilage hinge and describe the utility of ultrasound in directing the need for pre-treatment. Methods: 39 patients with minimally displaced lateral humeral condyle fractures and underwent ultrasound and arthrography examinations before operation from May 2018 to December 2019 were included in this study. The ultrasound and arthrography predictors of the cartilage hinge status were independently measured. Result of ultrasound and arthrography were compared.Results: The mean displacement of fractures was 3.1 mm (range, 2.0～5.0 cm). The arthrography showed an incomplete fracture in 24 patients (61.5%) and complete in 15 patients (38.5%). The ultrasound showed an incomplete fracture in 25 patients (64.1%) and complete in 14 patients (35.9%). The ultrasound and arthrography evaluations of the integrity of the articular surface were consistent in 92.3% of the cases, including 23 were predicted to have an intact articular surface, and 13 were predicted to have incongruity articular surface. There was no correlation between displacement and the fracture being complete on ultrasound. The Pearson coefficient value of ultrasound and arthrography for assessing the integrity of the articular surface was 0.837. Conclusions: Ultrasound and arthrography assessments of the integrity of the cartilage hinge status appear to be highly consistent. Ultrasound can be used as a complementary tool with arthrography to predict the integrity of the cartilage hinge status of patients with minimally displaced lateral humeral condyle fractures in children.Level of evidence: Retrospective study; level Ⅳ.

Background: Lateral humeral condyle fracture is the second most common intra-articular fracture in pediatric elbow. Objectives: The present study aimed to analyze the differences between X-ray and magnetic resonance imaging (MRI) in the evaluation of the stability of pediatric lateral humeral condyle fracture and the degree of fracture displacement. Methods: A total of 78 patients with acute elbow trauma were selected and hospitalized in our orthopedic department from July 2018-July 2019. All patients were examined with X-ray and MRI. The sensitivity and specificity of X-ray and MRI in the diagnosis of lateral humeral condyle fracture and the integrity of the trochlear cartilage chain fracture were calculated. The X-ray and MRI were examined respectively to check the value of lateral and posterior fracture space of lateral humeral condyle fracture. Results: Callus repair was observed according to the observation of fracture line during operation or the follow-up imaging examination of conservative treatment. It was confirmed that out of 78 patients with elbow joint trauma, 72 cases were diagnosed with the fracture of lateral condyle of humerus, and the other 6 patients were cured without fracture signs. The sensitivity of MRI in the diagnosis of pediatric lateral condylar fracture was 100%, which was significantly higher than that of X-ray (88.89%) (P<0.05). The results of X-ray and MRI in the diagnosis of pediatric lateral condylar fracture were generally consistent (kappa value = 0.465;< 0.01). Among the 72 confirmed cases, 35 subjects had a fracture of trochlear cartilage chain. The sensitivity of MRI in the diagnosis of pediatric fracture of lateral condyle of humerus was 97.14%, which was significantly higher than that of X-ray (62.86%) (P<0.05). The difference was statistically significant (P<0.05). The sensitivity of 3d-fs-fspgr or 3d-fspgr was significantly higher than that of fs-t2wi and fs-pdwi (P< 0.05). Conclusion: As evidenced by the obtained results, MRI was superior to X-ray in the diagnosis of pediatric humeral epicondylar fracture stability and evaluation of fracture displacement. Furthermore, 3d-fs-fspgr or 3d-fspgr was the best MR sequence to show the pediatric humeral epicondylar fracture. These findings can provide theoretical basis for the establishment of clinical treatment plan.

Unstable Fractures

Fractures of the lateral humeral condyle run a great risk of subsequent displacement. This is also true—although to a lesser extent—for primarily non-displaced or minimally displaced (≤2 mm) fractures. The present retrospective investigation aimed at defining radiographic criteria in order to predict the stability of non-displaced or minimally displaced fractures in 159 children. The fractures were classified according to radiographic criteria into 3 groups considered to represent stable, ambiguous and unstable fractures. Additional displacement while immobilized in plaster occurred in 2.6 per cent of the fractures classified as stable and in 44.4 per cent of those classified as unstable (p<0.001); in the ambiguous group subsequent displacement occurred in 24.1 per cent. It is concluded that the radiographic criteria should be useful to predict the stability of non-displaced or minimally displaced fractures of the lateral humeral condyle in children.
