Percutaneous cross-pinning versus two lateral entry pinning in Gartland type III pediatric supracondylar humerus fractures

Authors

Abstract

Background
Supracondylar humerus fracture is the most common elbow fracture in children aged 5–7 years, affecting boys more than girls and the majority of fractures are of the extension type. These fractures are usually associated with a number of complications including neurovascular injuries, malunion, and elbow stiffness. Gartland type III fractures are usually treated by closed reduction and percutaneous pinning.
Patients and methods
A prospective study was carried out on children with Gartland type III extension-type supracondylar humerus fractures. The patients were randomized to undergo fixation either with crossed pinning (group A) or two lateral pinning (group B). We compared both groups with regard to their passive elbow range of motion, Flynn’s criteria, Baumann’s angle, change in Baumann’s angle, and Skaggs method of grading of loss of reduction and complications.
Results
Group A included 33 patients with a mean age of 5.4 years and group B included 34 patients with a mean age of 4.9 years. Group B had a statistically significant shorter operative time and radiation time. At final follow-up, there were no statistically significant differences between group A and group B with respect to the average Baumann’s angle, change in the Baumann angle, range of elbow motion, Flynn’s grade, or Skaggs criteria. There were no cases of iatrogenic ulnar nerve injury in both groups.
Conclusion
If a standardized operative technique is followed in each method, then the result of both methods will be same in terms of safety and efficacy. Orthopedic surgeons treating unstable pediatric supracondylar humerus fractures should be familiar with both pinning techniqus.
