Hemiarthroplasty for proximal humerus fractures and for fracture sequelae: did not differ in their outcomes.

Background: The role of hemiarthroplasty (HA) in the management of proximal humerus fractures (PHFs) and their sequalae has evolved with the development of contemporary internal fixation techniques and the widespread use of the reverse total shoulder arthroplasty. However, HA may still have a role in certain acute PHFs as well as select fracture sequalae. The aim of this investigation was to evaluate the outcomes of HA when used in acute fractures and fracture sequelae.

Primary reverse shoulder arthroplasty using contemporary implants is associated with very low reoperation rates.

Background: The early results of reverse shoulder arthroplasty (RSA) were influenced to some extent by the use of first-generation implants and surgeons' learning curves, resulting in relatively high reoperation rates. The purpose of this study was to quantify the burden of and identify the indications for reoperation after primary RSA using contemporary implants and techniques.

Methods: A retrospective review of 1649 primary RSAs implanted consecutively between 2009 and 2015 at a single institution was conducted.

Intraobserver and interobserver reliability of the modified Walch classification using radiographs and computed tomography.

Background: The Walch classification was introduced to classify glenoid morphology in primary glenohumeral osteoarthritis. A modified Walch classification was recently proposed, with 2 additional categories, B3 (monoconcave glenoid with posterior bone loss leading to retroversion > 15° or subluxation > 70%) and D (excessive anterior subluxation), as well as a more precise definition of subtypes A2 and C. The purpose of this study was to evaluate the intraobserver and interobserver agreement of the modified Walch classification system using both plain radiographs and computed tomography (CT).
