In a random, placebo controlled, double blind study, collagenase injection therapy will be investigated for it's ability to lyse the adhesions associated with the shoulder capsule in adhesive capsulitis (frozen shoulder).~Treatment success may obviate the need for extensive physical therapy and/or shoulder arthroscopy (surgery) to correct this condition and restore normal and pain free shoulder motion.
The purpose of this study is to test collagenase injection therapy to dissolve adhesions causing frozen shoulder.
