Abstract
Introduction: Fracture of the lateral condyle of distal humerus in the pediatric population is a common problem. In children less than 13 year the distal humerus is only partially ossified and it is sometimes impossible to assess whether a fracture extends to the articular surface of distal humerus and whether or not there is a step off. Classic recommendations were to perform an open reduction in order to ensure perfect reduction. There are sporadic reports on use of arthrography or MRI studies
Aim of the Study: Retrospective study- intended to evaluate the clinical and radiographic outcome in children in whom the articular surface of distal humerus was evaluated by arthrography . Uppon arthrography results undisplaced fractures were percutaneously pinned and displaced fractures underwent formal open reduction and internal fixation.
Patients and Methods: 11 children mean age 7.8 (1.5–15) were enrolled in the study. Inclusion criteria was a fracture of lateral condyle of humerus suspected to be type II according to Jakob (the fracture is complete but is not diplaced out of the elbow joint). The mean follow up was 2.4y (13m-5.2y). Range of motion. Carrying angle were and neurovascular status were noted and compared with controlateral elbow. Actual X-rays were reviewed.
Results: The patient sample represent around 8% of the whole number of children treated in our Institution during 2000–2005. In 7 patients we were able to avoid open reduction and still to achieve excellent results. In 4 cases that were finally managed by open reduction the intraoperative findings fitted the arthrographic findings.
In Conclusion: Arthrography may prevent unnecessary open reductions for lateral condyle fractures in children.
