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.

Surgical outcomes of simple distal femur fractures in elderly patients treated with the minimally invasive plate osteosynthesis technique: can percutaneous cerclage wiring reduce the fracture healing time?
Achieving adequate reduction is difficult when performing minimally invasive plate osteosynthesis (MIPO) in elderly patients with simple distal femur fracture. This study aimed to evaluate the elderly patients who had undergone percutaneous wiring-assisted reduction with MIPO for simple distal femur fractures to determine the effect of this technique on reduction quality and fracture union. ⋯ Surgical treatment of simple spiral distal femur fractures with percutaneous cerclage wiring-assisted reduction and the MIPO technique in elderly patients resulted in better reduction and faster union time. Therefore, this technique could be a good solution if used in accordance with the indication.

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.

Comparative StudyThe accuracy of external calibration markers in digital templating using the double marker and single marker method: a comparative study.
Digital templating is an essential step in the preoperative planning of total hip arthroplasty (THA). Previous studies have suggested that templating with the double marker method may be more accurate than a single marker method in the general population and in obese patients. The purpose of this study was to compare the accuracy in the preoperative component selection between the King Mark calibration device and the conventional metal ball method. Additionally, we examined whether King Mark offered any advantage over the standard metal ball in the preoperative selection of component sizes for obese patients. ⋯ Our study found no difference between the King Mark method and the conventional metal ball method in the ability to accurately predict component sizes. In the subgroup of obese patients, the King Mark technique offered no advantage for accurately predicting component sizes.
