To analyze a prototype mobile C-arm image amplifier (Iso-C3D) in the evaluation of different joint fractures of the upper and lower limbs using multiplanar reconstruction (MPR). Different cadaver joint specimens (n = 14) were examined with a prototype (Iso-C3D, Siemens AG, Erlangen, Germany), plain radiographs (CR), and spiral computed tomography (CT). The motorized C-arm provides fluoroscopic images during a 190 degrees orbital rotation computing a 119-mm data cube. These three-dimensional data sets yielded MPR images, which were evaluated by two readers for the detection and extent of fracture lines. Initial data show that fractures were easily depicted and correctly classified on MPR images with the Iso-C3D and that there was no difference between the Iso-C and CT in the detection of fractures. The preliminary results suggest a remarkably good detection of joint fractures with the Iso-C3D. Studies in an adequate number of patients are required to elucidate whether these promising results can also be obtained in a clinical setting.

“…Auch die Weiterentwicklung der CT unter Anwendung von Spiraltechniken und dreidimensionallen (3D-)Rekonstruktionen erlaubt dem Unfallchirurgen eine genaue Darstellung von Knochenfrakturen im 3D-Raum mit beliebigen Rotationsmöglichkeiten und der Ansicht von allen Seiten [9,14].…”

Complete visualization of the joint surface is essential for correct assessment of tibial head fractures. Conventional tomography, computed tomography (CT), and magnetic resonance imaging (MRI) are compared in this prospective study. We examined 27 patients (19 suffering from B fractures and 8 from C fractures) from 1 January 1995 to 11 November 1998. Conventional tomography underestimated the fractures in 3 of the 19 cases of B fractures. Computed tomography underestimated two of these cases. MRI could not exactly depict the essential structures in three of the eight cases of C fractures because of edema and effusions. MRI identified complete cruciate ligament rupture in 6 of the 27 cases (18%) and 10 meniscal ruptures in 9 cases (33%: 6 medial meniscus, 4 lateral meniscus). Complete ruptures of the lateral collateral ligament were detected in five cases and medial collateral ligament ruptures in two cases. According to this, 63% of the patients suffered from relevant accompanying soft tissue injuries. The rate of soft tissue injuries increased up to 92% including the partial collateral ligament ruptures. Local hospital conditions permitting, X-ray-loaded conventional tomography should no longer be used in tibial head fractures. X-ray-free MRI is most efficient in cases of B fractures, which can in most cases be treated with a minimum of invasive techniques. Computed tomography is to be used in cases of C fractures that are regularly managed by open surgery accompanied by direct visualization of the inside of the knee joint.

“…Frakturen im proximalen, metaphysären Bereich der Tibia stellen bei der operativen Versorgung aufgrund anatomischer Besonderheiten eine spezielle Herausforderung dar. Die Schwierigkeit liegt unter anderem darin, dass diese Frakturen zur dorsalen Abkippung neigen und das proximale Tibiafragment leicht disloziert [1].…”
