The objective of this retrospective study was to correlate the Bado and Jupiter classifications with long-term results after operative treatment of Monteggia fractures in adults and to determine prognostic factors for functional outcome. Of 63 adult patients who sustained a Monteggia fracture in a ten-year period, 47 were available for follow-up after a mean time of 8.4 years (5 to 14). According to the Broberg and Morrey elbow scale, 22 patients (47%) had excellent, 12 (26%) good, nine (19%) fair and four (8%) poor results at the last follow-up. A total of 12 patients (26%) needed a second operation within 12 months of the initial operation. The mean Broberg and Morrey score was 87.2 (45 to 100) and the mean DASH score was 17.4 (0 to 70). There was a significant correlation between the two scores (p = 0.01). The following factors were found to be correlated with a poor clinical outcome: Bado type II fracture, Jupiter type IIa fracture, fracture of the radial head, coronoid fracture, and complications requiring further surgery.

Bado type II Monteggia fractures, and within this group, Jupiter type IIa fractures, are frequently associated with fractures of the radial head and the coronoid process, and should be considered as negative prognostic factors for functional long-term outcome. Patients with these types of fracture should be informed about the potential risk of functional deficits and the possible need for further surgery.

Intro: Traumatic atlanto-occipital dislocation (AOD) remains a seldom and severe injury which function-ally separates the head from the upper cervical spine and thus can lead to neurological compromise or death. We report on a survivor after AOD, who came back to sportive activity after operative sta-bilization C0–C2.

Case Report: The 32 year old polytraumatized racing-bicyclist was addmitted to our insitution after a crash. Initially, due to the lack of hard diagnostic signs the diagnosis AOD was missed. Thoroughly reevaluation and craniocervical diagnostics particluar dynamic roentgenogramms revealed the atlanto-occipital instability. Thus the patient underwent posterior fusion C0–C2 using a pedicular-rod-based cranio-cervical hardware-system (CerviFix). The patient gained full recovery and after 2 years of active physiotherapy he showed a favourable functional outcome and came back to sportive-cycling.

Discussion: Missing atlanto-occipital dislocation as well as secondary dislocation with conservative treatment of this rare entity can cause serious sequelae or lead to death. Thus a thorough diagnostic scheme has to be installed for cervical spine fractures including dynamic roentgenogramms contrary to fear of neu-rological compromise in this technique as well as CT and MRI. The knowledge based in literature suggest that any concomittant ligamentous instability in case of C0–C1 injury has to be stabilized by operative fusion as there is unsure clinical course, if treated in conservative manner predisposing for secondary hits, epecially in sportive individuals

Conclusion: Actually due to the lack of large single institution series, theres no evidence or proper guidelines concerning diagnostics and treatment of AOD. We recommend CT and dynamic roentgenogramms of the cervical spine in case of a suspected AOD. Dynamic x-rays clearify masked cervical spine in-stabilities including AOD and thus should be performed to reveal AOD prefering to MRI. The treatment of AOD utilizing anchor stable posterior rod-based systems enable early postoperative physiotherapy, rehabilitation and secure healing.
