Comparison of Two Methods of Subscapularis Management in Shoulder Arthroplasty: Tenotomy Versus Peel
This trial is active, not recruiting.
|Treatments||subscapularis tenotomy, subscapularis peel|
|Sponsor||Ottawa Hospital Research Institute|
|Collaborator||St. Joseph's Health Care London|
|Start date||August 2011|
|End date||April 2016|
|Trial size||80 participants|
|Trial identifier||NCT01404143, 2011-352|
What is the difference in subscapularis strength between two different methods of subscapularis mobilization: incision of the tendon (tenotomy) versus peel, as measured by a hand-held dynamometer in the belly-press position at one year post operative? It is the investigators' hypothesis that a peel of the subscapularis will result in greater strength, a higher healing rate, and a greater improvement in shoulder function and quality of life following shoulder replacement.
