Arthroplasty without HADM
Arthroplasty with HADM
Three - five (3 - 5) subjects with Eaton stage III-IV thumb CMC osteoarthritis undergo the basilar joint arthroplasty procedure without using a spacer constructed from human acellular matrix (HADM). Their postoperative DASH scores, grip strength, pinch strength, pain scale scores and quality of life questionnaires are compared to their preoperative scores. These subjects will be compared with a group of twenty-five (25) similar subjects who received the arthroplasty procedure with the use of the HADM spacer.
Twent-five (25) subjects with Eaton stage III-IV thumb CMC osteoarthritis undergo the basilar joint arthroplasty procedure with an interposition arthroplasty technique using a spacer constructed from human acellular matrix (HADM). Their postoperative DASH scores, grip strength, pinch strength, pain scale scores and quality of life questionnaires are compared to their preoperative scores. These subjects will be compared with a group of three - five (3 - 5) similar subjects who received the arthroplasty procedure without the use of the HADM spacer.
