Bado III Monteggia in children - treatment options and outcome: an ultrasound control study

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.

Pediatric Monteggia fractures: a single-center study of the management of 40 patients

INTRODUCTION

Early identification and conservative management of pediatric Monteggia fractures has been shown to correlate with good results. Nevertheless, several authors advocate more aggressive management with open reduction and internal fixation (ORIF) for unstable fractures. We herein present the experience of a tertiary pediatric hospital in the management of Monteggia fractures.

METHODS

Forty patients with Monteggia fractures (26 male and 14 female) were admitted and treated over a period of 20 years (1989 to 2009). The age of the patients ranged between 3 and 14 years (mean 7.5 y). On the basis of the Bado classification, 28 fractures were type I, 3 were type II, 8 type III, and 1 fracture was classified as type IV. Out of the 40 patients, 32 were managed with manipulation under anesthesia (MUA) and above-elbow plaster, whereas 8 underwent ORIF of the ulna.

RESULTS

To assess outcomes, the Bruce, Harvey, and Wilson scoring system was used. Range of movement, pain, and deformity were evaluated to class an outcome as excellent, good, fair, or poor. Patients were followed up for an average of 4.6 years (range, 1 to 7 y). All patients in the MUA group had excellent results. In the ORIF group, 8 out of 9 patients had good results.

DISCUSSION AND CONCLUSIONS

According to our recorded experience, conservative management of Monteggia fractures, when indicated, results in excellent outcomes. In cases where emergency MUA fails to achieve or maintain reduction, the choice of ORIF has also demonstrated good results. Early diagnosis and management are of paramount importance as mismanaged cases demonstrate less satisfactory results.
