OBJECTIVES To: 1) describe perceptions of satisfaction with and usability of the DEKA Arm and preferences for the DEKA Arm or personal prosthesis; 2) compare perceptions of satisfaction and usability by DEKA Arm configuration level; and 3) evaluate satisfaction and usability for study completers and non-completers; and for those who did and did not want to receive a DEKA Arm. METHODS The stud...

This clinical study was performed to analyze the midterm results and potential complications of the reverse prosthesis in different diagnosis. Forty-five consecutive patients with Grammont prosthesis were evaluated clinically and radiographically with a mean follow-up of 40 months (range, 24-72 months). The indication was a massive and irreparable cuff tear associated with arthrosis (CTA) in 21...

A simple unconstrained shoulder prosthesis has been used in 22 patients (25 shoulders) with incapacitating pain and severely damaged joints who, because of age or generalised rheumatoid disease, have limited functional requirements. All reported good and lasting pain relief. Improvement in range of movement was modest, but there was marked improvement in function. In this group of patients, rot...

Background and purpose - The number of patients where shoulder hemiarthroplasty (SHA) is an option is still substantial. Descriptive analyses performed by the Swedish Shoulder Arthroplasty Registry (SSAR) showed that while patients receiving SHA designs, i.e. resurfacing hemi (RH) and stemmed hemi (SH), reported similar shoulder functionality and quality of life, the revision rate for RH (12%) ...

The cybernetic interface within an upper-limb prosthesis facilitates a Human–Machine interaction and ultimately control of the limb. A coherent flow between phantom motion subsequent actuation limb to produce desired gesture hinges heavily upon physiological sensing source its ability acquire quality signals, alongside appropriate decoding these intent signals with aid signal processing algorit...

There are theoretical and practical advantages to modular rather than monoblock designs of prostheses for shoulder arthroplasty, but there are no reported studies which specifically compare the clinical and radiological results of their use. We have compared the results of unconstrained total shoulder arthroplasty for osteoarthritis using both types of implant. The monoblock design was used bet...
