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.

Results of a Highly Porous Metal-Backed Cementless Patella Implant: A Minimum 5-Year Follow-Up.

Initial design cementless metal-backed patellar implants failed due to multiple reasons including implant design, use of first-generation polyethylene, and surgical technique. This study evaluates clinical outcomes and survivorship of total knee arthroplasty (TKA) using a current generation highly porous metal-backed patellar component. One-hundred twenty-five consecutive primary cementless TKAs with a compression molded highly porous metal-backed patella were reviewed.

Manipulation Following Primary Total Knee Arthroplasty is Associated With Increased Rates of Infection and Revision.

Background: Stiffness following total knee arthroplasty (TKA) is a disabling complication and manipulation under anesthesia (MUA) is often performed as an early intervention. Few studies have focused on the revision risk, infection risk, demographics, and clinical outcomes in Medicare patients undergoing MUA following primary TKA.

Methods: We reviewed 142,440 patients who had primary TKA from a national database and identified 3,652 patients (2.

Rifampin and tobramycin combination with PMMA antibiotic cement.

Rifampin is a powerful antibiotic used in the treatment of biofilm-forming bacteria with studies supporting its use in PMMA cement. However, it has not been widely accepted for its use in PMMA cement due to a perception that it is unable to solidify in a timely manner. The technique described consists of ratio of aminoglycoside and rifampin that reduces time to solidification to approximately 15-20 min.

Comparative Analysis of Bibliometric, Authorship, and Collaboration Trends Over the Past 30-Year Publication History of the Journal of Orthopaedic Trauma and Injury.

Objectives: In the scientific and medical field, authorship has become increasingly important for tenure and career advancement in addition to improvement in medical care. It was the purpose of this study to investigate changes in bibliometric variables, authorship, and collaboration trends in the Journal of Orthopaedic Trauma (JOT) and Injury over a 30-year period.

Methods: A bibliometric analysis was completed for all manuscripts meeting the inclusion criteria and published throughout 1 representative year of each decade over the past 30 years.

MMP14 is a novel target of PTH signaling in osteocytes that controls resorption by regulating soluble RANKL production.

Parathyroid hormone (PTH) affects the skeleton by acting on osteocytes (Ots) in bone through yet unclear mechanisms. We report that matrix metalloproteinase 14 (MMP14) expression/activity are increased in bones from mice with genetic constitutive activation (ca) of the PTH receptor 1 (PTH1R) in Ots (caPTH1R) and in bones from mice exposed to elevated PTH levels but not in mice lacking [conditional knockout (cKO)] the PTH1R in Ots (cKOPTH1R). Furthermore, PTH upregulates MMP14 in human bone cultures and in Ot-enriched bones from floxed control mice but not from cKOPTH1R mice.

Bibliometric Analysis of Female Authorship Trends and Collaboration Dynamics Over JBMR's 30-Year History.

In academia, authorship is considered a currency and is important for career advancement. As the Journal of Bone and Mineral Research (JBMR) is the highest-ranked journal in the field of bone, muscle, and mineral metabolism and is the official publication of the American Society for Bone and Mineral Research, we sought to examine authorship changes over JBMR's 30-year history. Two bibliometric methods were used to collect the data.
