Abstract:

Objective　To observe the clinical effects of arthroscopicacromiaoplasty and rotator cuff repair for treatment of Subacromiai Impingement and Rotator Cuff Tear.　Methods　from  2007 ,20 cases of Subacromiai Impingement and Rotator Cuff Tear, there were 8 male and 12 female,aged 25～72 years old，with an average of 45 years old. 16 cases had nontraumatic history，and 4 cases had traumatic history．Patients had the symptoms of shoulder pain at night, and Restricted activities，positive Neer sign ,positive pain arc and impact injection test．Preoperative MRI scans showed high signal in the rotator cuff in T2:10 cases with massive large rotator cuff tear,6 eases with middle tear，4 cases with small tear can be seen under the scope. They are treated with arthroscopic acromiaoplasty. 13 cases of rotator cuff tears were repaired with suture anchor．In preoperative and final follow-up，shoulder ASES score and Constant-Mureley score were used for function evaluation.　Results　The follow-up of 24 months(10 to 32)months．The excellent and good rate of ASES score was 85％，the excellent and good rate of Constant-Murley score was 90％．Postoperative scores were significantly different(ASES：P<0.001，t=11.343；Constant-Murley：P<0.001,t=14.356). Conclusion Subacromiai Impingement and Rotator Cuff Tear is the common casue of shoulder pain and dysfunction, which can be effectively treated with Arthroscopic Acromioplasy and Rotator Cuff Repair.
