Thermogravimetric analysis of cancellous bone of humerus head in patients undergoing total shoulder arthroplasty

Use of PROMIS for Patients Undergoing Primary Total Shoulder Arthroplasty

BACKGROUND The Patient-Reported Outcomes Measurement Information System (PROMIS) consists of question banks for health domains through computer adaptive testing (CAT). HYPOTHESIS For patients with glenohumeral arthritis, (1) there would be high correlation between traditional patient-reported outcome (PRO) measures and the PROMIS upper extremity item bank (PROMIS UE) and PROMIS physical funct...

Failure of Anatomic Total Shoulder Arthroplasty with Revision to Another Anatomic Total Shoulder Arthroplasty

Background: While outcomes of primary anatomic total shoulder arthroplasty (aTSA) are generally favorable, resultsafter revision procedures are less reliable. This study examines the functional outcomes, complications, and implantsurvival in patients who underwent revision of aTSA to aTSA.Methods: Patients who underwent revision aTSA were identified from 2008-2015. Demographic, clinical, surgic...

Reverse Total Shoulder Arthroplasty in Proximal Humerus Fractures

Bone Remodelling of the Humerus after a Shoulder Arthroplasty

In this work computational models are developed to analyze bone remodeling of the humerus after a shoulder arthroplasty using either a cemented or press-fit stem. Bone is modelled as a porous material, characterized by its local density. The bone remodelling model is based on a global optimization criterion by the minimization of a function which takes into account both structural stiffness and...

Increasing Use of Reverse Total Shoulder Arthroplasty for Proximal Humerus Fractures in Elderly Patients.

This study described surgical treatment patterns for proximal humerus fractures among elderly patients, focusing on reverse total shoulder arthroplasty (TSA), and evaluated how the type of fixation affects inpatient factors (cost, length of stay), transfusion rates, and patient disposition (home vs skilled nursing facility). With Nationwide Inpatient Sample data from 2011 to 2013, the authors i...
