Single-Dose Intravenous Tranexamic Acid Does Not Increase Venous Thromboembolic Rate or Complication Rate During Hip Arthroscopy.

Purpose: To determine whether tranexamic acid (TXA) is safe to administer preoperatively in patients undergoing hip arthroscopy by comparing the venous thromboembolic rate and complication rate between patients who did and did not receive TXA preoperatively.

Methods: This was a multicenter consecutive-cohort series of patients who underwent arthroscopic hip surgery between 2014 and 2021. The 2 cohorts comprised patients who did and did not receive TXA preoperatively (single dose of 1-2 g), after a practice change.

Surface Evaluation of Gyroid Structures for Manufacturing Rubber-Textile Conveyor Belt Carcasses Using Micro-CT.

Gyroid structures are among the most widely used three-dimensional elements produced by various additive manufacturing technologies. This paper focuses on a metrological analysis of Flexfill 92A material specimens with a relative density (25 to 85%) using industrial computer tomography. The results show that for a given structure, the best method is to use surface determination with the closure of internal defects in the material.

Identification of the Natural Frequencies of Oscillations of Perforated Vibrosurfaces with Holes of Complex Geometry.

The reliability of perforated vibrosurfaces is one of the main parameters of the efficiency of their operation in many technological processes. Existing methods for studying vibrosurfaces with standard single holes and the corresponding results cannot be used to study the reliability of vibration surfaces with holes of complex geometric shapes. The proposed method is based on the experimental modal identification of the parameters of natural oscillations, the parallel creation of a numerical model using the finite element method, and the comparison of the results.

Not All Proximal Humerus Fractures Do Well Without Surgery: Anterior Translation Predicts the Need for Surgery.

Objectives: To evaluate the effect of translation on a large series of low-energy proximal humerus fractures initially treated nonoperatively.

Design: Retrospective multicenter analysis.

Setting: Five level-one trauma centers.

Early Outcomes of Proximal Humerus Fractures in Adults Treated With Locked Plate Fixation Compared with Nonoperative Treatment: An Age-, Comorbidity-, and Fracture Morphology-Matched Analysis.

Objectives: To compare patient-reported outcomes (PROs), range of motion (ROM), and complication rates for proximal humerus fractures managed nonoperatively or with open reduction internal fixation (ORIF).

Design: Retrospective cohort.

Setting: Academic level 1 trauma center.
