Objective To investigate and analyze the clinical effect of shoulder joint impingement syndrome treated with shoulder arthroscopy combined with drugs.MethodsFrom January 2015 to December 2016, 20 patients suffering from impingement syndrome in People's Hospital of Fenghua District were selected as the subjects in this study.Randomly selected patients were divided into the control group and the experimental group two groups, each group of patients were 10 cases.The control group in patients with arthroscopic exploration plus subacromial decompression molding, experimental group was given drug treatment on the basis of the control group, before the end of surgery in patients with intra-articular injection of sodium hyaluronate and Compound Betamethasone Injection.The therapeutic effects of the experimental group and the control group were compared.ResultsAfter the corresponding treatment, there were no complications in the experimental group and the control group.The VAS scores, shoulder abduction and external rotation angles of the experimental group and the control group were significantly higher than those of the control group, with statistical difference (P<0.05).After treatment, the VAS score of the experimental group was (1.7±0.3) points, the external rotation angle was (36.5±13.5) degrees, and the shoulder abduction was (110.5±3.7) degrees.The score of VAS in the experimental group was significantly lower than that in the control group, and there was a statistical difference (P<0.05).ConclusionThe clinical effect of arthroscopic subacromial impingement syndrome combined with drug treatment, can effectively relieve the pain of the patients, improve the patient's shoulder to a certain extent, with further clinical promotion and application significance.
