Review Comparative Study
Surgical fixation of Vancouver type B1 periprosthetic femur fractures: a systematic review.
Vancouver type B1 periprosthetic femur fractures occur around a stable implant and are typically treated with open reduction and internal fixation (ORIF). Different fixation techniques are described in the literature, and there is a lack of consensus regarding the best operative fixation strategy. The purpose of this investigation was to systematically review and compare the most commonly used fixation strategies for these fractures. ⋯ In total, 333 patients identified with an overall rate of 5% nonunion, 6% malunion, 5% infection, 4% hardware failure, 9% reoperation, and 15% total complications. When comparing outcomes for different modes of fixation, compared with cable plate/compression plate systems, locking plates had a significantly higher rate of nonunion (3% vs. 9% P = 0.02) and a trend toward a higher rate of hardware failure (2% vs. 7%, P = 0.07). There are limitations to this study, and further investigation with high-quality randomized controlled trials is needed to effectively compare treatment strategies.

The null hypothesis of this study states that routine axial computed tomography (CT) images are obtained at a consistent and reproducible orientation relative to the sacrum. The secondary null hypothesis states that there is no difference in the measurement of the safe zone for placement of iliosacral screws when using routine axial CT images and standardized reconstructions in defined planes perpendicular and parallel to the sacrum. ⋯ Our null hypotheses were rejected: routine axial CT images were found to be at widely ranging orientations relative to the sacrum, and standardized CT images (CT inlet and CT outlet) demonstrated statistically significant differences in measurements of safe zones compared with routine axial CT images. Furthermore, the CT inlet and CT outlet views provide additional information regarding sacral landmarks that could be useful for preoperative planning.

Proximal humerus fractures have rarely been associated with injuries to the axillary artery. Most of the fractures described have been Neer 2-part surgical neck fractures with medialization of the shaft fragment and resultant laceration or thrombosis of the axillary artery. No intraoperative deaths have been reported. ⋯ There were 2 mortalities, 1 intraoperative. After a thorough review of the English literature, we identified an additional 11 cases of axillary artery injury associated with proximal humerus fracture. The purpose of this study was to heighten the clinical suspicion of this vascular injury in patients with proximal humerus fracture dislocations and surgical neck fractures with shaft medialization, as well as to review pathogenesis and guide management decisions.

Stable fixation of displaced type II distal clavicle fractures presents a challenge to the surgeon because of distal fragment comminution and the large deforming forces created by the weight of the arm. We hypothesized that suture fixation around the coracoid and interfragmentary suture fixation would adequately counteract these forces and lead to a high rate of union and restoration of function. ⋯ Therapeutic level IV.
