JUST Ossenhan Reverse Shoulder System Approved by NMPA
On January 28, 2026, the Ossenhan Reverse Shoulder System, part of the JUST Shoulder Reconstruction Product Line, officially received approval from the National Medical Products Administration (NMPA) of China.
This approval represents a significant milestone for JUST Medical Devices and marks an important breakthrough in the field of shoulder arthroplasty. It reflects the company’s continuous commitment to innovation, independent R&D, and the development of high-end orthopedic implants.
With the increasing demand for effective treatment of complex shoulder disorders in an aging population, the Ossenhan Reverse Shoulder System provides a reliable, high-quality domestic solution for shoulder joint reconstruction.
Product Features and Clinical Value
The Ossenhan Reverse Shoulder System is designed to enhance implant stability, improve range of motion, and support long-term clinical outcomes:
Titanium and Hydroxyapatite (HA) Composite Coating
Applied to both humeral and glenoid components, the composite coating offers high bonding strength, excellent corrosion resistance, superior biocompatibility, and strong osteoconductivity, promoting long-term osseointegration.
Vitamin E–Blended Highly Cross-Linked UHMWPE Liner
Optimized material formulation improves wear resistance and oxidation stability, effectively extending implant service life.
Eccentric Glenoid Design
The eccentric spherical glenoid increases adduction angle, improves shoulder range of motion during adduction and abduction, and reduces the risk of mechanical impingement and scapular notching.
135° Neck–Shaft Angle Humeral Stem
Compared with conventional 155° designs, the 135° neck–shaft angle enables better anatomical reconstruction, enhances the deltoid lever arm, improves joint stability, increases mobility, and reduces inferior scapular contact.
Osseointegration Performance
A 26-week bone implantation study evaluated 12 implant sites. The results demonstrated abundant new bone formation at the implant interfaces, with tight bonding between the coating and newly formed bone. No fibrous capsule formation or inflammatory cell infiltration was observed.
The approval of the Ossenhan Reverse Shoulder System further enriches the JUST Shoulder Reconstruction Product Line and strengthens the company’s portfolio in advanced orthopedic solutions, offering clinicians and patients a dependable domestic option for shoulder reconstruction.
