Are Shoulders with A Reverse Shoulder Prosthesis Strong Enough? A Pilot Study
BACKGROUND It has been suggested that limited active ROM of reverse shoulder prostheses relates to lack of strength. However, the postoperative strength has not been quantified. QUESTIONS/PURPOSES We therefore measured joint torques in patients with reverse shoulder prostheses and correlated torques with functional scores. METHODS We recruited 33 patients (age, 72 ± 8 years) with a reverse ...
متن کاملBiomechanical considerations of the normal and rotator cuff deficient shoulders and the reverse shoulder prosthesis
ont matter & 2006 006.10.004 thor. [email protected] Summary The treatment of combined glenohumeral arthritis and massive rotator cuff deficiency remains a unique challenge. Prosthetic reconstruction is aimed at restoring the normal kinematics of the glenohumeral joint. The reverse shoulder prosthesis medialises the centre of rotation of the glenohumeral joint, thereby lengthening the deltoid lev...
متن کاملDesign rationale for a posterior/superior offset reverse shoulder prosthesis.
INTRODUCTION A computer model quantified and compared muscle lengths and moment arms of two different reverse shoulder arthroplasty humeral tray designs during two different motions. METHODS The computer model simulated internal/ external rotation and abduction in the scapular plane for the normal shoulder, the 38 mm non-offset, and the 38 mm posterior-superior offset reverse shoulders. Muscl...
متن کاملEvolution of the reverse total shoulder prosthesis.
Over the last decade, reverse total shoulder arthroplasty has gained significant popularity due to its ability to address difficult reconstructive shoulder problems that could not be adequately treated in the past. The concept of the reverse shoulder prosthesis was introduced in the 1970s, but the initial attempts were associated with high complication and implant failure rates. The pioneering ...
متن کاملSix-year experience with the Delta III reverse shoulder prosthesis.
PURPOSE To report the clinical and radiographic results and complications of the Delta III reverse prosthesis. METHODS 24 women and 2 men aged 62 to 84 (mean, 75) years underwent total shoulder replacement using the Delta III reverse prosthesis. Patient diagnoses were massive rotator cuff tear (n=20), disabling sequelae of proximal humeral fractures (n=3), and failure of an unconstrained arth...
