Bado III Monteggia in children - treatment options and outcome: an ultrasound control study.
Journal of pediatric orthopedics. Part B(2023)
Abstract
The Bado III Monteggia lesion is an uncommon fracture in children. Radial head dislocation can occur due to intra- or extra-articular fractures of the olecranon. In extra-articular ulnar fractures, heterogeneous operative methods are proposed in different case reports. The objective of this study is to determine if closed reduction of the ulnar fracture, either without osteosynthesis or by using TEN, is a safe treatment option. In a multicenter study, we retrospectively analyzed 26 children who were treated for an extra-articular proximal metaphyseal ulnar fracture with dislocation of the radial head. These patients underwent a follow-up examination after an average of four years. The investigation included a physical examination, visualization of the elbow anatomy, and specifically, the radial head retention in the joint by ultrasound. Of the 26 patients, 18 were treated by closed reduction and intramedullary osteosynthesis (TEN), 7 were treated by closed reduction and cast immobilization without osteosynthesis, and 1 child was treated by open reduction of the ulna and plate osteosynthesis. In the follow-up examination, 25 children showed an excellent outcome, as well as inapparent sonography. Although this is a retrospective study with different types of treatment, closed reduction of the ulna with or without osteosynthesis appears to be effective. We believe that the correct primary reduction is the key to an excellent long-term outcome. Regarding the invasiveness of the treatment, reduction without or with TEN osteosynthesis should be the preferred approach in extra-articular pediatric Bado III fractures.
