Radiological and Clinical Outcomes of Pediatric Patients with a Supracondylar Humerus Fracture Surgically Treated with Closed Reduction and Percutaneous Pinning

Abstract

Objectives: It was aimed to evaluate the clinical and radiological results of patients operated on with closed reduction and pinning due to pediatric supracondylar humerus fractures. Materials and methods: The radiological and clinical results of 100 patients operated on with closed reduction and percutaneous pinning for pediatric supracondylar humerus fractures in the Department of Orthopedics and Traumatology were examined between January 2015 and February 2022. Clinical results were evaluated by performing cosmetic and functional scores defined by Flynn. Closed reduction and percutaneous pinning techniques were used in surgical treatment. Results: In our study, 59 patients were male (59%), and 41 were female (41%). The average age of all patients is 6.21 +/- 2.85 years. According to the Gartland classification, 21 patients' fractures were type IIA (21%), 12 patients' fractures were type IIB (12%), 51 patients' fractures were type III (51%), and 16 patients' fractures were type IV (16%). The average number of pins used in the treatment is 2.55 +/- 0.50. The elbow bearing angle of the operated side of the patients was an average of 6.53 +/- 3.29 degrees, the humerocapitellar angle was an average of 41.97 +/- 3.08 degrees, and the lateral humerocapitellar angle was an average of 50.17 +/- 3.58 degrees. Fifty-one patients had stage 0 (51%), 23 patients had stage 1 (23%), 23 patients had stage 2 (23%), and three patients had stage 3 (3%) residual sagittal plane deformity. According to the Flynn criteria, 92 patients had excellent functional results (92%), seven patients had good results (7%), and one patient had fair results (1%). Regarding cosmetic results, 91 patients had excellent results (91%), six patients had good results (6%), and three patients had fair results (3%). Conclusion: Supracondylar humerus fractures are common in children and can cause serious complications. Closed reduction and percutaneous pinning techniques are effective treatment methods in the treatment of displaced supracondylar humerus fractures.
