This study will compare total shoulder arthroplasty (TSA) with an augmented glenoid component and reverse shoulder arthroplasty (RSA) procedures, in participants with advanced glenohumeral osteoarthritis aged 65 years and older, who also present with greater than 15 degrees of glenoid retroversion, in the context of a prospective, randomized controlled trial to determine the optimal treatment in this patient population.Read full original descriptionShow less
Study Evaluating Reverse Versus Anatomic Total Shoulder Arthroplasty in Shoulders With Greater Than 15 Degrees of Retroversion in the Treatment of Osteoarthritis: Protocol
This study will compare total shoulder arthroplasty (TSA) with an augmented glenoid component and reverse shoulder arthroplasty (RSA) procedures, in participants with advanced glenohumeral osteoarthritis aged 65 years and older, who also present with greater than 15 degrees of glenoid retroversion, in the context of a prospective, randomized controlled trial to determine the optimal treatment in this patient population.
Inclusion: Diagnosis of idiopathic shoulder OA; Patients who have failed standard non-surgical management of their shoulder OA who would benefit from a shoulder arthroplasty. Failed medical management will be defined as persistent pain and disability despite adequate standard non-operative management for at least 6 months. Medical management will be defined as: a) The use of drugs including analgesics and nonsteroidal anti-inflammatory drugs, b) Physiotherapy consisting of stretching, strengthening and local modalities (ultrasound, cryotherapy, etc.), c) Activity modification; Imaging, and intra-operative findings confirming advanced glenohumeral cartilage loss; Patients with a glenoid deficiency and >15 degrees of glenoid retroversion up to a maximum of 26 degrees of glenoid retroversion (i.e. -15.1, -17, -20…etc.); 65 years of age and older.
Exclusion: History of previous shoulder surgery on affected side; Active joint or systemic infection; Major medical illness (life expectancy less than 1 year or unacceptably high operative risk); Psychiatric illness that precludes informed consent; Rotator cuff arthropathy; Significant muscle paralysis; Charcot's arthropathy; Unable to understand the consent form/process; Pregnancy; Unwilling to be followed for the duration of the study; Retroversion cannot be surgically corrected to within 10 degrees of neutral; Rheumatoid arthritis in the affected shoulder.
