Background: The paediatric age group between 5 to 7 years encounters supracondylar fracture of humerus as the commonest fracture due to trauma following fall on an outstreached hand. There are different methods of pinning configurations for K wire insertion to stabilize a displaced fracture. The present study is aimed to assess the outcomes of different pinning techniques among children with supracondylar fracture humerus. Methods: This hospital based cross sectional study was conducted among 60 children aged 4 to 14 years presenting with Gartland type III supracondylar fracture of humerus. During the reduction surgery four type of Kirshner wire insertion techniques were performed on different children. Patients were followed upto 6 weeks post surgery. The radiological and functional outcomes were assessed by comparing the Carrying angle, Baumann’s angle, anterior humeral line, movements of elbow joint and union of the fracture line. All the data was compiled in Microsoft excel and analysed using SPSS 26.0. Results: With a mean age of 8.6(±2.6) years and age ranging between 4-14 years, total 60 children were included in the study. 17 (28.3%) cases were operated by two cross K-wire, 18 (30%) were by two lateral K-wire divergent, 15 (25%) were by two lateral K-wire parallel and 10 (16.7%) cases were operated by three-pin techniques. Cross pinning showed 6 cases of ulnar nerve injury and no differences were found in ROM, carrying angle, Baumann’s angle and anterior humeral line between the four methods of pinning. Position of the anterior humeral line also showed no significant difference. Flynn’s crietria of outcome also showed no significant difference. Conclusion:This study suggests that there are no significant differences in functional and radiological outcomes among the four types of Kirshner wire fixation inGartlandtype III supracondylar humerus fractures in children.
