    Notes: Abstract In a study the results recorded in 34 surgically treated patients with specific or unspecific spondylodiscitis after dorsoventral one-stage instrumentation with CDI and anterior grafting (group 1) were compared with those obtained in a group of 38 patients treated with anterior CDH instrumentation in combination with anterior grafting (group 2). The mean observation periods were 48.4 (19–82) months in group 1 and 29.0 (8–54) months in group 2. In both groups the infection healed after fusion without a secondary operation. In group 1 the mean values for blood loss, operating time, length of hospital stay and fusion length (3.5 segments) were significant higher than those in group 2; in particular, the fusion length was shorter (1.3 segments) in group 2. Only 8 patients in group 1 were treated with postoperative external support. The mean preoperative segmental angle of 18.2° (group 1) was corrected by a mean of 11.9°, and the reposition loss during follow-up amounted to an average of 2.7°. Group 2 showed a mean preoperative segmental deformity angle of 13.4°, which was corrected by 11.6°, and the loss of reposition was 2.9° on average. Even in florid spondylodiscitis a short-range anterior fusion of the affected spinal segment can be performed with a primarystable implant, avoiding a second operation without an increased risk of infection-related dislocation. In the authors' own experience a secondary dorsal operation can be avoided except in the case segment L-5/S-1, the fast mobilization without external support allows a up-to-date treatment in this severe spinal disease.

    Description / Table of Contents: Zusammenfassung Der Begriff „okkulte Fraktur“ kennzeichnet das Fehlen sichtbarer Frakturzeichen in der zur Erstdiagnose durchgeführten konventionellen Radiographie bei dennoch vorhandener Fraktur. Die Diagnosestellung gelingt erst im Verlauf oder mittels weiterführender Diagnostik. Die hierzu durchgeführten Szintigraphie- und CT-(Computertomographie)Untersuchungen verfügen jedoch nur über eine mäßige Sensitivität und Spezifität. Mit der Magnetresonanztomographie (MRT) steht ein Verfahren zur Verfügung, das sowohl die Frühdiagnose der „okkulten Fraktur“ als auch die Diagnose etwaiger chondraler und ligamentärer Begleitverletzungen erlaubt. In der vorliegenden Studie berichten wir über 23 Patienten mit einer traumatischen Fraktur in 5 verschiedenen anatomischen Regionen, bei denen die Diagnose bei negativem Röntgenbefund mit der MRT gestellt werden konnte.
    Notes: Summary The term “occult fracture” defines the lack of visible fracture signs in conventional radiography although a fracture exists. The diagnosis is made in the sequel or through further diagnostic procedures. The use of scintigraphy and CT examinations is limited by their moderate sensitivity and specificity. In contrast, MRI is a diagnostic tool that allows early diagnosis of a fracture and of accompanying chondral or ligament damage. We report on 23 patients with traumatic fractures at 5 different anatomical sites, all of which were negative by x-ray, but the diagnosis could subsequently be made with MRI.
