AI Article Synopsis
- The study evaluated the dimensions of the proximal humerus in 81 patients (41 men and 40 women) to determine if gender-specific prostheses could optimize fit during glenohumeral arthroplasty.
- Significant differences in size were found for the humeral head height, width, and distance to the greater tuberosity between genders, but not in the anatomical relationships.
- The relationship between the humeral head-greater tuberosity distance and humeral head inclination was significant for both men and women, indicating important shared anatomical features across genders.
Article Abstract
Background: During glenohumeral arthroplasty, not only should the dimensions of the prosthesis match the normal anatomy but also the relationship of the humeral head-greater tuberosity and humeral head inclination should be replicated to avoid muscular dysfunction. To date there is no evidence whether fit could be optimized with gender-specific prostheses.
Materials And Methods: Magnetic resonance (MR) arthrography imaging was used to evaluate 81 proximal humeral scans for 5 different anatomic parameters. The study group included 41 men and 40 women, aged 20 to 62 years. Anatomic parameters, including the humeral head height, humeral head width, humeral head-greater tuberosity distance, humeral head inclination, and glenoid version were measured using Horizon Rad Station 11.0 to evaluate the MR imaging.
Results: The humeral head height, width, and distance to the greater tuberosity were significantly different in size between genders. However, none of the anatomic relationships were different. The humeral head-greater tuberosity distance significantly correlated with the humeral head inclination in both men (r = 0.338; P < .05) and women (r = 0.448; P < .005).
Conclusion: We conclude that there are no significant differences in glenohumeral relationships between genders.

Reverse shoulder arthroplasty in revision surgery-Indications and results.
PLoS One
January 2025
Division of Arthroscopic and special Joint Surgery / Sports Injuries, Department of Orthopedics, Trauma and Plastic Surgery, University of Leipzig, Leipzig, Germany.
Background: The number of reverse shoulder arthroplasty (RSA) procedures performed worldwide has increased over the last 10 years, with a corresponding increase in revision shoulder arthroplasty (SRSA). SRSA is often used for post-traumatic revision surgery in cases of infections and failure of anatomical prostheses. Data on outcomes with specific detail for each indication for the prosthetic solution as a secondary treatment are scarce, and inhomogeneous.

Background: Arthroscopic repair with the biceps rerouting (BR) technique has been determined to lead to promising clinical and biomechanical outcomes for treating large-to-massive rotator cuff tears (LMRCTs). However, the in vivo effects of BR on glenohumeral kinematics during functional shoulder movements have not been fully elucidated.
Purpose: To investigate whether BR provides a better restoration of shoulder kinematics compared with conventional rotator cuff repair (RCR).

Introduction: Stress shielding remains a concern following total shoulder arthroplasty using press-fit short humeral stems. While the effect of alterations in implant geometry, positioning, and sizing on stress shielding have been investigated, the effects of coverage of the cortical boundary of the resection plane have not yet been fully explored. The purpose of this study was to quantify the effect of improved cortical coverage using elliptical vs.

Aims: Hemiarthroplasty (HA) and total shoulder arthroplasty (TSA) are often the preferred forms of treatment for patients with atraumatic avascular necrosis of the humeral head when conservative treatment fails. Little has been reported about the survival of HA and TSA for this indication. The aim of this study was to investigate the differences in revision rates between HA and TSA in these patients, to determine whether one of these implants has a superior survival and may be a better choice in the treatment of this condition.

The humeral head is the second most common anatomical site of osteonecrosis after the femoral head. Studies have reported satisfactory clinical outcomes after shoulder arthroplasty to treat osteonecrosis of the humeral head (ONHH). However, there are concerns regarding implant longevity in relatively young patients.
