Objective: To study the shoulder anatomy characteristics of the Chinese people and to design a new kind of humeral prosthesis, which could realize the adjustment in three-dimensional space and be adjusted repeatedly, based on Chinese humeral anatomy characteristics.
Methods: A double-gear structure as a rotating part was adopted to design the structure of this new kind humeral prosthesis.
Results: The humeral prosthesis could satisfy both the needs of Chinese individual shoulder characteristics and the Westerners' demands.
Conclusion: A novel concept of shoulder prosthesis design with a strong application value in design and development of the new prosthesis is proposed.

The Use of the Anterior Labral Circumferential Onlay Technique to Reconstruct the Anterior Labrum and Biomechanically Restore Glenohumeral Joint Stability.
Orthop J Sports Med
December 2024
Steadman Philippon Research Institute, Vail, Colorado, USA.
Background: A labral injury contributes to glenohumeral instability. The Anterior Labral Circumferential Onlay Technique (ALCOT) reconstructs the labrum using the long head of the biceps tendon.
Hypothesis: The ALCOT would restore glenohumeral joint stability in a cadaveric model without glenoid bone loss (1) comparable to the native state and (2) comparable to the Latarjet procedure.
The Rotator Cuff Footprint in Filipinos: A Cadaveric Study.
Acta Med Philipp
October 2023
Department of Orthopedics, Philippine General Hospital, University of the Philippines Manila.
Article Synopsis
- Rotator cuff tears are a common cause of shoulder pain, and proper repair requires understanding the anatomy of the rotator cuff footprint, especially after conservative treatments fail.!* -
- This study aimed to measure the dimensions of the rotator cuff footprint in Filipino cadavers, specifically looking at the supraspinatus, infraspinatus, subscapularis, and teres minor muscles.!* -
- The results indicated that the average dimensions of the rotator cuff footprint were smaller in this population compared to previous studies, though the shapes were consistent with existing research.!*
Inverted-bearing reverse shoulder arthroplasty: long-term survivorship, complications, clinical, and radiological outcomes.
J Shoulder Elbow Surg
January 2025
Department of Biomedical Sciences, Humanitas University, Pieve Emanuele, Milan, Italy; IRCCS Humanitas Research Hospital, Rozzano, Milan, Italy.
Background: Inverted-bearing reverse shoulder arthroplasty (IB-RSA) is characterized by a polyethylene glenosphere and a metallic humeral liner to minimize polyethylene wear and debris secondary to impingement between the humerus and glenoid neck. IB-RSA long-term survivorship, complication and revision rates, as well as clinical and radiographic outcomes have not been reported yet.
Methods: This is a monocentric retrospective study on a consecutive series of 151 patients who underwent primary IB-RSA from January 2009 to September 2015 and were evaluated clinically and radiologically at the minimum 8-year follow-up.

Bone tumors of the upper limb are a common cause of bone pain and pathological fractures in both old and young populations. Surgical reconstruction and limb salvage have become valid options for these patients despite this kind of surgery being challenging due to the need for wide bone resection and the involvement of surrounding soft tissues. Computer-assisted technology helps the surgeon in pre-operative planning and in designing customized implants.

Abteilung Kinderorthopädie, Kinderchirurgische Universitätsklinik, Inselspital Bern, Freiburgstraße 15, 3010, Bern, Schweiz.
Background: Fractures of the lateral condyle of the humerus in children are articular fractures with difficult diagnostics due to the incompletely ossified elbow joint. The aim of this study was to evaluate the method of treatment at initial presentation and to analyze the frequency of subsequent displacement during follow-up.
Material And Method: Retrospective analysis of the frequency of primary fracture dislocation and subsequent displacement of fractures of the lateral condyle of the humerus in children under 16 years of age between 2004 and 2021.
