Early fixation of the humeral component in stemless total shoulder arthroplasty : a radiostereometric and clinical study with 24-month follow-up.

Aims: Stemless humeral implants have been developed to overcome stem-related complications in total shoulder arthroplasty (TSA). However, stemless implant designs may hypothetically result in less stable initial fixation, potentially affecting long-term survival. The aim of this study is to investigate early fixation and migration patterns of the stemless humeral component of the Simpliciti Shoulder System and to evaluate clinical outcomes.

Long Head of Biceps Tenotomy Is Not Inferior to Suprapectoral Tenodesis in Arthroscopic Repair of Nontraumatic Rotator Cuff Tears: A Multicenter, Non-inferiority, Randomized, Controlled Clinical Trial.

Purpose: To determine if long head of the biceps (LHB) tenotomy is not inferior to suprapectoral LHB tenodesis when performed in conjunction with arthroscopic repair of small- to medium-sized nontraumatic rotator cuff tears.

Methods: This multicenter, randomized, non-inferiority trial recruited 100 participants older than 50 years who had a supraspinatus and/or infraspinatus tear sagittally smaller than 3 cm and arthroscopically confirmed LHB pathology. During arthroscopic rotator cuff repair, we randomized 48 patients to undergo suprapectoral LHB tenodesis and 52 patients to undergo LHB tenotomy.

Reverse or Hemi Shoulder Arthroplasty in Proximal Humerus Fractures: A Single-Blinded Prospective Multicenter Randomized Clinical Trial.

Objectives: To compare outcomes between hemiarthroplasty (HA) and reversed shoulder arthroplasty (RSA) as a treatment for dislocated 3-part and 4-part proximal humerus fractures in the elderly population.

Design: Prospective multicenter randomized controlled trial.

Setting: Three Level-1 trauma centers.

Total ankle replacement outcome in low volume centers: short-term followup.

Background: The indication for total ankle replacement (TAR) as an alternative to ankle fusion continues to be a much-debated topic. The reported survival of TAR at midterm followup is approximately 90%. The aim of this study was to compare functional outcome and survival of TAR in low volume centers versus high volume centers.
