Functional Improvement after Sub-Acromial Corticosteroid Injection in Patient with Shoulder Impingement Syndrome

Background: Sub-acromial impingement syndrome (SAIS) is the most common disorder of shoulder. Conservative treatment is the first choice, often with corticosteroid injection or different physiotherapy interventions, or both. So we aimed to assess the mean reduction in shoulder pain and disability index (SPADI) score after administration of sub-acromial corticosteroid injections for management of SAIS. Objectives: To determine the mean reduction in SPADI score after administration of Sub-acromial corticosteroid injections for management of sub-acromial impingement syndrome. Material and Methods: The Quasi – experimental study was conducted in Department of Orthopedic Surgery, Mayo Hospital Lahore from November 2013 to august 2014. 150 cases were enrolled in this study. Then baseline SPADI score was noted. Patients were injected with sub-acromial injections of 40 mg triamcinolone acetonide mixed with 4.5 ml of 2% lignocaine under aseptic measures. All patients did exercises, consisting of pendulum and range of motion under care of physiotherapist. Each patient was followed-up in OPD for assessment of shoulder function according to SPADI score at 1, 3 and 6 weeks after administration of injection. The result was analyzed by using SP-SS version 16. Results: The mean age of the patients was 44.58 ± 11.48 years. There were 46.67% males and 53.33% females in this study. The mean SPADI score of the patients at baseline was noted as 75.94 ± 7.73 which was reduced to 46.25 ± 5.62 after 6 weeks. Conclusion: Our study results concluded that Sub-acromial corticosteroid injection is effective in treatment of shoulder impingement syndrome.
