An intuitive and simple technique for accurate insertion point selection and precise Poller (blocking) screw insertion.
Although indirect reduction with intramedullary (IM) nailing is the gold standard for long bone fractures, IM nailing in meta-diaphyseal fractures often results in malalignment. Placement of Poller (blocking) screws is an attractive and useful technique in these situations; however, the selection of accurate placement points and the placement process itself are often complicated. This paper proposes an intuitive, simple, and clear technique for selecting the location of Poller screw placement that can be used in either the anteroposterior or lateral view regardless of the fracture type and discusses techniques for Poller screw placement that enable displacement correction.

Local osteo-enhancement of osteoporotic vertebra with a triphasic bone implant material increases strength-a biomechanical study.
The aim of this study was to assess the biomechanical properties of intact vertebra augmented using a local osteo-enhancement procedure to inject a triphasic calcium sulfate/calcium phosphate implant material. ⋯ This biomechanical study shows that a local osteo-enhancement procedure using a triphasic implant material significantly increases the load at failure and displacement at failure in cadaveric osteoporotic vertebra.

Evaluation of fetuin-A as a predictor of outcome after surgery for osteoporotic fracture of the proximal femur.
In the elderly, osteoporotic fractures of the femur are associated with high morbidity and mortality. At the time of hospitalization and during pre-operative care identification of patients at risk for poor outcome despite an otherwise good clinical condition is challenging. We hypothesized that the serum concentration of fetuin-A during post-operative recovery might serve as a biomarker. ⋯ Our results are in favor of fetuin-A as an important factor for fracture healing but do not support an association between fetuin-A at time of follow-up examination and either SSO or oPP.

Double-plate compound osteosynthesis for pathological fractures of the proximal femur: high survivorship and low complication rate.
Management of pathological fractures of the proximal femur is often challenging. Compound double-plate osteosynthesis has been specifically developed for surgical treatment of these pathological fractures. To our knowledge, this study represents the largest series to date of double-plate compound osteosynthesis with the longest follow-up. ⋯ Double-plate compound osteosynthesis is a valuable treatment option for pathological fractures in proximal femur with good functional results.

Results of plate fixation for humerus fractures in a large single-center cohort.
This study aims to describe the results of plate fixation in one of the largest single-center cohorts that employs plate fixation as the golden standard. Additionally, risk factors related to a negative outcome were identified. ⋯ Plate fixation for humeral shaft fractures has low risks of complications. It should be emphasized that the complications can be further minimized with a greater surgical expertise and by refraining from performing a surgery during out-office hours.
