Anterolateral rotatory instability of the elbow: a possible etiology of primary osteoarthritis.

Background: The purpose of this study is to describe anterolateral rotatory instability (ALRI) as a possible etiology of primary osteoarthritis (OA) of the elbow.

Methods: We examined 76 fresh frozen cadaveric elbows (male:female, 56:20; mean age, 81 years) for patterns of cartilage erosion that could be due to ALRI. These included erosions on the lateral trochlear ridge (LTR) lesion, crescent rim of the radial head (RC) lesion or the ventral capitellum (VC) lesion.

TikTok and frozen shoulder: a cross-sectional study of social media content quality.

Purpose: This study aimed to assess the validity and informational value of the material provided on TikTok regarding frozen shoulders. The hypothesis was that the video content on this platform would not provide adequate and valid information.

Methods: The current study focused on frozen shoulder videos on the TikTok social media platform.

Reverse Shoulder Arthroplasty for Proximal Humeral Fractures: Is the Bigliani-Flatow Stem Suitable for Tuberosity Fixation and Healing?

: The aim of the study was to investigate the clinical, functional, and radiographic results of patients affected by three- or four-part proximal humeral fractures treated with reverse total shoulder arthroplasty, to investigate whether a prosthetic stem nonspecifically designed for fractures (i.e., the Bigliani-Flatow stem) promotes tuberosities' healing, and to evaluate the impact of tuberosity fixation and healing on the outcomes.

TikTok content as a source of health education regarding epicondylitis: a content analysis.

Purpose: This study aimed to assess the validity and informational value of TikTok content about epicondylitis. The hypothesis tested herein was that TikTok video content would not provide adequate and valid information.

Methods: The term "epicondylitis" was used as a keyword to comprehensively search for TikTok videos, and the first 100 videos that were retrieved were subsequently included for analysis.

A Rare Case of Open (Gustilo II) Periprosthetic Fracture (Vancouver B2) in a Polytraumatized Patient.

Periprosthetic femoral fracture is the third most frequent complication after total hip replacement (THR). It is mainly caused by low-energy trauma in the elderly. Open periprosthetic fractures are significantly rarer and are caused by high-energy trauma.
