Features of Angel Shoulder Replacement System
•The Asymmetrically fratures stem designed anterolateral wing: located at the fracture line, does not affect the reduction of the bone fragments, guides the correct reduction of the bone fragments, supports the large and small tuberosity bone fragments, facilitates the fixation of the bone fragments, guides the installation direction of the prosthesis, and determines the posterior tilt angle of the prosthesis.
•The Humeral Stem Platform Design with Spherical ConnectionInterface Enables seamless conversion to anatomic or reverse shoulder akhroplasty without stem removal. Allows intraoperative adjustment of prosthetic anatomical parameters.
•The glenoid component features a downward suspension designand a large-diameter glenosphere.
•The anatomic replicator allows independent adjustment of thehumeral head inclination by +/-7.5°, resulting in a neck-shaftangle range of 125°-140° and a version range of +/-7.5°.
Indication of Angel Shoulder Replacement System
•Primary Osteoarthritis (glenohumeral joint) with an intact, functioning rotator cuff.
•Rheumatoid Arthritis without significant rotator cuff erosion or deficiency.
•Post-Traumatic Arthritis (following previous fracture or dislocation).
•Avascular Necrosis (AVN) of the humeral head (e.g., post-Corticosteroid use, sickle cell disease, or trauma).
•Failed Hemiarthroplasty (painful previous partial replacement)
•Irreparable Rotator Cuff Tear with Pseudoparalysis (inability to lift the arm actively).
•Rotator Cuff Tear Arthropathy (arthritis combined with massive cuff tear).
•Complex Proximal Humerus Fractures (3-part, 4-part, or fracture-dislocations), especially in elderly patients (>70 years).
•Failed Anatomic Total Shoulder (revision surgery due to cuff failure or loosening).
•Severe Glenohumeral Arthritis with a Deficient Rotator Cuff.
