Short Term Effectiveness of Intraatricular Injection of Methylprednisolone Acetate in Subacromial Impingement Syndrome in a tertiary care hospital.

Objective: To determine mean decrease in VAS pain score of intraarticular injection of methyl prednisolone acetate in patients of subacromial impingement syndrome. Methods: Its Descriptive Case Series/ Quasi experimental study. Study was conducted in department of Orthopedics UnitI, Jinnah hospital Lahore. Study completed in Six months i.e. from June 2014 to December 2014.After taking an informed consent, 70 newly diagnosed cases of Subacromial impingement syndrome by history and examination (described by the patient as pain in subacromial space when the humerus was elevated or internally rotated and tested by having the patient place his hand on the unaffected shoulder and gradually forward flexing the shoulder (positive impingement sign)which have not received any kind of treatment were included. Results: Effectiveness of intraarticular injection of methyl prednisolone acetate was measured on visual analogue scale (VAS) from 0 to 10 by VAS score after 6 weeks. 70 patients with mean age of 36.2 ± 10.6 years were included. 61 patients (75.7%) were male, 10 patients (14.3%) had gout and 20% were diabetic. Mean pretreatment VAS score was 5.03 ± 1.58 while mean post-treatment VAS score was 3.86 ± 0.839. Mean reduction was 1.17 ± 1.57 ranged from 2 to 6. There was non-significant association of age and diabetes with mean reduction in VAS score while female gender and gout were significantly and negatively associated with treatment outcome. It is concluded that mean reduction in VAS score after 6 weeks of treatment of subacromial impingement syndrome after intra articular methylprednisolone injection is 1.17 ± 1.57 and acceptable. Conclusion: It is concluded that intraatricular injection of methyl prednisolone injection is efficacious and effective for treatment of Subacromial impingement syndrome in Pakistani population.
