1. [Three-dimensional fluoroscopy-based navigation with the VBS® cage for defect augmentation of the pelvis due to metastatic tumor treated].

Abstract

Destruction of the sacrum due to metastatic tumors may lead to a significant instability of the posterior pelvic ring. This often causes pain, immobility, and subsequently a loss of quality of life. The surgical treatment options are limited. A new technique is presented using a cement augmented expandable cage placed percutaneously using 3D fluoroscopy-based navigation with or without an additional osteosynthesis.

Abstract

We compared in a prospective study including 82 patients treated with ORIF of an intraarticular calcaneus fracture the quality of fluoroscopy, intraoperatively Iso-C(3D) and postoperative CT-scans. Therefore the posterior facet of the calcaneus (PFOC) was divided into three sectors. Joint steps and fracture gaps were detected by two independent investigators and statistically analysed. Another focus was to evaluate if the findings due to intraoperatively Iso-C(3D) assessment performed by the surgeon were correct and subsequently influenced the surgical procedure. There were no statistically differences between the Iso-C(3D)- and CT findings concerning joint steps or fracture gaps in PFOC sectors I-III. With fluoroscopy an assessment of the PFOC sectors I and II was not possible. In six cases (7.3%), intraoperative reduction was redone after performing an Iso-C(3D) scan. In ten cases, 12 malpositioned screws were replaced (12.2%/14.6%). These results suggest that intraoperative 3D Iso-C(3D) imaging provides a high diagnostic reliability. By careful assessment of the images the surgeons receive information which could lead to a change of the operative strategy.

Abstract

In distal intraarticular humerus fractures primary stable osteosynthesis is essential for early mobilization of the elbow joint. Double-plate osteosynthesis techniques using different configurations are the gold standard. In the literature plate position is sometimes discussed controversially. In cases of distal humerus fractures (type AO 13C3) with metaphyseal comminution, as well as in elderly patients with poor bone quality, utilizing locking plates with angular stability was found to have increased structural properties with regard to primary fixation stability. The dorsal approach with osteotomy of the olecranon seems to be very effective in open reduction and internal fixation of this type of fracture. One new development is the anatomically preformed plate-fixation systems such as the LCP-System for distal humerus (Synthes). This study presents our first experience with this system in 11 cases of open reduction and internal fixation of type AO 13C3 distal humerus fractures. The system-specific features and intraoperative options were analyzed.
