Evaluation of early functional outcome of arthroscopic decompression in chronic primary sub-acromial impingement syndrome

<b>Background:</b> Sub-Acromial Impingement Syndrome (SAIS) spectrum ranges from acute inflammation to chronic degeneration of the bursa and rotator cuff tendons in sub-acromial space. It may lead a full-thickness tear degenerative joint disease shoulder girdle leading functional loss disability if not treated early adequately. This study aimed determine outcome arthroscopic decompression SAIS due mechanical causes.<br /> <b>Material methods:</b> was prospective cohort study. Patients were operated on arthroscopically for between September 2018 March 2020. Thirty-five patients with range 20 65 years age diagnosed clinically primary impingement syndrome meeting inclusion criteria included this All under initially kept at least four weeks course conservative treatment persisted having symptoms surgically decompression. The UCLA (The University California Los Angeles) rating scale used assess function. assessment done pre-operative period, weeks, 12 16 post surgery.<br <b>Results:</b> Compared function score end non-operative treatment, showed statistically significant improvement 16th week post-arthroscopic subacromial (p<0.0001).<br <b>Conclusion:</b> concludes that provides good extrinsic causes such as shape slope acromion absence (total or near total) after follow-up.
