Accuracy and reliability of spinal navigation: An analysis of over 1000 pedicle screws.
To estimate the rate of pedicle screw malpositioning associated with placing pedicle screws using intraoperative computed tomography (CT)-guided spinal navigation. ⋯ Using O-arm-based intra-operative three-dimensional scans for navigation can improve the reliability, accuracy, and safety of pedicle screw placement, reducing the risk for reoperation and hospitalization due to implant-related complications. Further improvement may be achieved by adequate consideration of potential sources of errors.

Dual plate fixation results in improved union rates in comminuted distal femur fractures compared to single plate fixation.
The treatment of distal femur fractures with extensive metaphyseal comminution is frequently complicated by high rates of nonunion and varus collapse. Dual plating with lateral and medial locking plates for these types of fractures has shown promising results in the recent literature. We hypothesize that dual plating of comminuted distal femur fractures leads to higher union rates and lower revision rates compared to an isolated lateral locking plate. ⋯ Level 3. Retrospective Cohort Study.

Fracture-related infections in HIV infected patients: A systematic review and meta-analysis.
To conduct a systematic review and meta-analysis comparing the incidence of fracture-related infections (FRI) following surgical management of closed and open fractures in HIV-positive and HIV-negative patients. ⋯ While there are few large prospective studies, the available data suggests that before the introduction antiretroviral therapy HIV infection was associated with a greater risk of FRI. In the post-antiretroviral era HIV infected patients did not show an increased risk of FRI.
