referring to the Eclipse shoulder prosthesis
In case of a massive rotator cuff lesion associated with a severe arthrosis (rotator cuff tear arthropathy) the application of an inverse prosthesis is suggested since the engine keeping constant the rotation centre of the humeral head in the glenoid cavity cannot be used.
The inverse prosthesis usually represents the last attempt to regain range of motion in the shoulder.
Dr. Costouros specializes in the comprehensive treatment of shoulder disorders using both arthroscopic and open surgical techniques. He is Board-Certified by the American Board of Orthopedic Surgery, a Fellow of the American Academy of Orthopaedic Surgeons and the American College of Surgeons, and has a Certificate of Added Qualification (CAQ) in Sports Medicine. He has particular expertise in traditional and reverse shoulder replacements, stemless shoulder arthroplasty, rotator cuff repair, the treatment of shoulder instability, revision shoulder surgery, and the treatment of sports injuries and fractures of the clavicle and shoulder girdle. He has developed innovative techniques and devices which are FDA-approved and in clinical use worldwide.
He is Past President of the Northern California Orthopaedic Society, Northern California Chapter of the Western Orthopaedic Association, and the Leroy C. Abbott Orthopaedic Society. He is an active member of the society of American Shoulder and Elbow Surgeons (ASES), American Academy of Orthopaedic Surgeons (AAOS), Arthroscopy Association of North America (AANA), European Shoulder and Elbow Society (SECEC), and International Society of Arthroscopy, Knee Surgery, and Sports Medicine (ISAKOS). His research is focused on enhancing clinical outcomes using molecular mediators, stem cells, biologics, and the design of state-of-the-art implants used in shoulder surgery.
Eclipse Stemless Shoulder Arthroplasty - Arthrex
Dr. Costouros specializes in the arthroscopic and open treatment of shoulder and elbow disorders derived from sports injuries, arthritis, fractures, compressive neuropathies, and failed prior surgeries. He has made significant award-winning research discoveries in the molecular etiology and treatment of arthritis and cartilage injuries.
He has special expertise in the reverse total shoulder replacement, management of massive and irreparable rotator cuff tears, revision surgery, tendon transfers, fractures of the shoulder girdle, and the treatment of sports-related disorders and instability of the shoulder in overhead athletes using arthroscopic techniques.
His research focuses on improving our understanding of cartilage injury and arthritis at the cellular level, specifically the development of methods to modulate programmed cell death or apoptosis. He also is involved in the development of cell-based strategies in improving outcomes following rotator cuff repair and better understanding the causes of rotator cuff disease.
Dr. Costouros continues to be interested in the development of instruments to analyze surgical outcomes and the creation of registries which allow surgeons to better understand patient-specific outcomes, implant longevity, wear mechanisms, and how surgeons can consistently deliver the best results following shoulder and elbow surgery.
A Prospective, Randomized, Multicenter Study comparing the Safety and Effectiveness of Arthrex's Eclipse™ Shoulder to the Univers™ II Shoulder Prosthesis in patients with a degenerative joint disease.
The Arthrex Eclipse Prosthesis (Arthrex, Naples, USA) ..
Arthroscopic repair of posterior shoulder instability is becoming an accepted method of treatment. Most surgeons perform this procedure with the patient in a lateral decubitus position to facilitate access to the posterior glenoid. We have developed an accessory portal placed through the midportion of the rotator cuff that allows easy and complete viewing of the posterior glenohumeral joint when the patient is in a beach chair position and does not require the use of traction. This portal provides a superior-to-inferior view of the posterior glenoid rim and capsule and allows use of anterior and posterior routine portals for posterior Bankart repair. In this study, the technique of posterior labral repair in the beach chair position with use of the trans-cuff portal is described, and preliminary results in 5 patients at an average follow-up of 24 months are presented. Through this approach, we were able to place 3 anchors, with the lowest at the 7 o'clock position (for a right shoulder), in all patients. Mean American Shoulder Elbow Surgeons (ASES) score improved from 53 +/- 15 preoperatively to 87 +/- 8 postoperatively (P
